Chapter 5: An Overwrought Relief

---

Later that afternoon, the entire party of Ylissean soldiers marched on the broad dirt road that led them back home and away from the woods where Frederick had attempted to train the young princesses. The bright green grass of the meadows flanked the long line of knights, sorcerers and healers who rode calmly back to the castle, for even despite the injuries sustained by some on the caravans, all of them would eventually recover thanks to the arts of the magical healers. As on the way there, Frederick and Sully leaded the line of mounted fighters, both of them still clad in their usual enormous pieces of armor; but this time Sully gazed upon Robin and Cynthia whenever she had the chance, trying to confirm her suspicions on what had exactly happened to Lucina earlier that day. And the couple rode behind them, acting overly affectionate as usual.

"I'm so glad you made it back then, Robin!" she chirped with cheerful liveliness. "Not like any of them could've bested me, but seeing how you cast that spell… Kapeeeew! You just blasted them into bits!" she declared excitedly as her boyfriend drew a shy smile on his face.

"The Fire Tome has the potential to turn any man to ashes, quite literally…" he said, unsure of what to say. He never knew exactly how to respond to compliments other than thanking, but to hear one coming from Cynthia certainly warmed him on the inside.

"You've GOT to stop being so cute!" she said puffing her cheeks. Cynthia loved it when Robin smiled, and she could read his mood depending on how his lips shifted. And right now, his facial expression was so gentle she also felt a warm sensation flourishing on her chest.

"A-Ah, Cynthia!" said Robin, who blushed slightly before his girlfriend started pinching his cheeks as if to a child.

"Hehe, sorry! I can't help it!" Chuckled the princess, caressing his face lovingly.

"Hey, you two lovebirds! Clam it up back there!" cried an annoyed Sully in front of them. "Geez, they're worse than Chrom and Sumia…" she muttered in a low voice only Frederick could hear, and he gasped loudly when he heard his wife speak like that of the King. But Sully pretended not to have said anything at all before the captain burst into his usual declamation on the honor and might of the royal family, making the red-headed fighter roll her eyes slightly irritated.

So they rode on the vanguard of the caravan, Frederick elicited a lengthy amount of deeds done by Chrom in an attempt to restore his honor in the eyes of an annoyed Sully while Cynthia and Robin cuddled the other as best as they could considering they were still riding their horses. The soldiers around them couldn't speak their minds, but it was easy to see they were entertained by the barter between their commanders, and their mood was more than jolly. Behind them, two wooden wagons rolled, pulled by heavy horses and carried most of the wounded, who laid in packs of hay while magicians dressed in white robes casted healing spells on them with a comforting chant, and streams of white light emerged from their hands and closed the open wounds on their bodies; and their healing arts comforted their minds from anguish and concern as their limbs regained their spent energy.

It was in this section of the line that Lucina rode quietly on her silver mare, next to the wagons and behind a group of young knights in copper armor. From that safe distance she could see the vanguard of the caravan where Cynthia and Robin shared another of the intimate moments the elder princess yearned for. But there was no way she would allow another incident to occur because of the complex feelings she had developed for both of them; the lovely way they shared every moment they spent together, the sweet tone Robin used when he spoke to Cynthia and how her younger sister reciprocated and delivered sweet pecks on his lips filled Lucina with a warm glow. Without realizing, she paddled her mare on the sides with the heels of the Pegasus Knight boots, closing the distance between them as she stared at them longingly, absent. She felt naturally attracted to the way they loved each other… and it was agonizing to see it from close by. And no one could ever know she harbored such feelings for them, which was the reason she had decided to stay away from them for the rest of the journey, or at least keep a respectable distance from them hoping none of the soldiers would notice anything strange going on.

She let out a low anxious sigh and shook her head, trying to collect herself. Lucina had been on longer horseback rides by distance during campaigns, including some after devastating losses to the Grimleal and yet somehow this one felt like the longest she'd ever endured. Sure, some of her compatriots had doubtless noticed she was now wearing a Pegasus Knight uniform instead of her own soaked clothes, but only Cynthia knew she was without underwear. The only thing preventing her backside from becoming a scandal at the moment was a lack of wind and the fact that Cynthia's own generous proportions meant there was enough material for Lucina to push under her bum for coverage. If the wind did pick up… Lucina shuddered at the thought again.

Unfortunately for the thoroughly over stimulated princess, when she shut her eyes thinking about exposing her backside, all she could see was her sister's; her tush bouncing rhythmically with each step when she walked, not a care in the world to be had when she egged Lucina on to fondle her. To compound the sense of frustration that was never far away, she heard Cynthia's salacious giggles as though she were only feet away. When Lucina's horse slowed its pace jerkily, the elder princess opened her eyes and saw that the giggles she heard were not just figments of her imagination. Cynthia was riding as close to Robin as possible without their mounts bumping into each other. Lucina's lusty frustrated feelings were extinguished and replaced by the familiar lonely jealousy she often felt when observing her sister's carefree whirlwind romancing from afar. 'Maybe it was one of the privileges of being a younger sibling that you were allowed to be more carefree,' Lucina reasoned.

"Hey Robin?" playfully said Cynthia.

"Yes, Cynthia?"

"When we went through that last thicket back there, I felt some branches land on my back. Can you brush them off for me, pretty please?" she pleaded, making eyes at the tactician.

"Sure thing, Cyn-" but when he approached her from behind and saw her bottom, he realized he had fallen into one of the teases that tortured Lucina so badly. "…You little devil." he muttered with a smile on his face.

"Hmm?" Cynthia acted innocently.

"Riding around bare-assed? I should give that a big smack. That way the world knows that ass is mine." Robin growled.

"What if that's exactly what I want?" she taunted him with one of her devilish grins. "What if as soon as we are back in Ylisstol, I swap out my horse here for something else to ride? Namely that big throbbing bulge in your pants, hmm?"

Cynthia raised the bet, proving she enjoys teasing not only to poor Lucina, but even her boyfriend in front of everyone. The younger princess leaned forward to expose more of her butt to his view, daring and bolder, and used the firm muscles of her thighs to shake her voluptuous cheeks up and down, displaying the jiggling motions of her bouncing bum. Although she was being discrete, as if leaning forward to reach for something, it didn't prevent Robin from staring at her arse agape and exhaling in lust. His erection got harder, and he found himself unable to utter a single word.

"You'd like to see more of this, wouldn't you?" she taunted.

"Oh… yeah…" muttered the tactician, gulping.

"And I'd bounce them for you…" she whispered seductively after a brief giggle. "Like this."

Giving a demonstration of sheer lust, she raised her bare butt up allowing Robin to see its glorious curvaceous glory and slammed it down on her saddle, and the slapping sound of her cheeks against the leather seat was enough to make his cock twitch inside his pants. But she didn't stop, but continued slapping her cheeks against the leather seat over and over. And every single time her arse bounced on the saddle, he felt the bulge between his legs grow larger, HARDER.

Amused, Cynthia couldn't help but giggle again, and this time she turned around to see the motions of her jiggling cheeks and make sure nobody unwanted was checking her out. But when she saw Lucina looking in her direction, the grin on her lips turned wider. She took the reins and directed her horse a little to the left, allowing her sister full frontal view of the erotic show she meant only for Robin. But having Lucina watching was an unexpected bonus.

And as expected, it was tortuous for the elder princess to see the almost obscene motions of Cynthia's wide bum. So fleshy, jiggling delightfully all over as she shook it in vertical movements that became more and more abrupt by the second. It took merely a moment before Lucina felt her skin turn feverishly hot just as the familiar tingling sensation stemming from her crotch coursed throughout her body, becoming more and more intense at her lips, her earlobes, her nipples and groin.

'No… not again, please not again!' She thought and shut her eyes tight, but the lewd movements of her sister remained burned in her retina, and she could still see them even with her eyes shut, tricked by her own desire. She began salivating and swallowed the entirety of it, and she realized she was grinding against the saddle unconsciously, easing a bit of her lust by rubbing her groin against the hard end of the saddle. "Hah… hah… hah…" her breathing became more and more intense, and she couldn't help but open her eyes again to see the immense bouncing cheeks of her sister shaking up and down, slapping as they collided one against the other. She couldn't avoid even fantasizing on how Cynthia's thick arse would make the same slapping noise when bouncing on Robin's cock, causing her to wet herself uncontrollably.

But her loud panting had almost turned into a moan, and it took Robin out of Cynthia's curvaceous figure for a moment causing him to turn his head in Lucina's direction. As soon as she saw Robin's white hair turn, she tried to look away and hold her breath, pretending nothing had happened dismayed by her embarrassment. But the tactician was no fool, and he realized Lucina was watching the same as he was, or she wouldn't be that blushed and agitated. He blinked confused, unsure if his deduction was correct, and turned back to his girlfriend to find her sitting on the saddle no longer shaking her bum… possibly intentionally. Cynthia even whistled while looking at the afternoon sky, feigning a casual innocence.

'Lucina… was aroused…?' he said to himself, genuinely astonished. Why else would Cynthia be acting so casual out of the sudden? She enjoyed teasing him, and doing what she wasn't allowed to in the direct situation. So why would she stop like that?

The slight shivering on Lucina's hands left the young tactician thinking… while she herself thought a lot to herself.

It was remarkable to Lucina that nobody else saw the display, or even heard just how filthy the conversation between Robin and her sister was. Not that it was anybody else's business but to be so open about which pieces of furniture were going to become covered in bodily fluids and the methods for doing so was bizarre to the older, more immodest princess. Still, she felt both conflicted and aroused at them just as she had for the last couple of weeks, and to see them at it again merely fueled her desire and sparked her to fantasize about them. Anyone else would've thought Lucina absentmindedness was due to her concerns about the bandits they had faced previously, or fulfilling her duties as a princess; but the truth was she had found herself in such intense situations, be that spying on them, watching from afar, or being teased to the point of torture by Cynthia, that every time she had a moment to spare her mind began making fantasies on its own, turning her on to the point she felt she was boiling on the inside.

Even though Cynthia's voluptuous figure seemed more slender in a regular Pegasus Knight uniform, she could tell Robin desired her the same. But now he knew she wasn't wearing anything beneath the uniform, and she wished Robin looked at her just as he was looking at Cynthia. After all, she wasn't wearing any underwear either! Maybe it'd arouse him too…

'You wouldn't complain if Robin noticed you were currently without panties, and you'd be a damned liar if you said you wouldn't be open to being thrown down on a bed, and fucked until you couldn't shout from release anymore.' said a sultry voice in Lucina's head that matched Cynthia's tone by the lake.

'But I'd only want Robin to notice. Even I can see Cynthia is exposing herself…' Lucina argued with her inner dialogue.

'Only because you are riding within earshot. If you weren't so curious about the naughty things that she's planning, you'd be way further back and your sister's big, round, slappable arse wouldn't even be on your radar. Let us not forget those bosoms either, that you'd fondle in a heartbeat if you wouldn't get caught.' retorted her inner voice growing impatient with Lucina's waffling.

Blood rushed to her face turning her cheeks redder by the second, and she shook her head trying to regain composure. Lucina desperately craved to live in the flesh of the sexual intensity of the couple, but at the same time she felt glad she wasn't noticed. Maybe she wanted only Robin to notice her. The princess thought her jealousy could turn into a crime if she can't try to step up her game and perhaps do something to get the tactician's attention; but she knew it was wrong to even think of doing something like that to Cynthia: it was Cynthia's boyfriend for Naga's sake!

She sighed, flustered. Who else could Lucina find without being afraid of exposure?

A horse neighed loudly behind her and she turned frightened, not because of the horse itself, but because if anyone got close enough, and if the hem of her skirt rose, they could see her naked bottom. A young squire in dark leather armor had lost control of his steed, and the beast was trotting at increasing speed outside the formation of the rest of the riders.

'Get away, get away, please get away!' a paranoid Lucina said to herself squeezing her eyes shut tight, but she heard the squire's voice closer to her.

"Calm down boy! Easy!" he yelled.

The elder princess couldn't take any risk: she had to help him, or be exposed in front of the rest of the army in case the squire collided against her. When the young man rode past her, she extended her arm in an attempt to calm the beast down. Instead, it tried to buck its rider off. The horse was the same color of a hazelnut, and it raised its hindquarters into the air while kicking out with its hind legs alarming the rest of the horses around it, but fortunately its movements drove it closer to Lucina's mare and the princess could get a hold of the reins before without much effort. But then the hazelnut beast bucked to the other side and the princess was forced to wield the leather reins with a strength only the men who had seen her engaged in combat were used to, for she pulled them with one hand and pulled the boy with the other right before he fell. Her silver mare neighed in discomfort and for a moment and dashed forward while at the same time the squire's horse bucked, pushing him too far to the right, so his head ended up falling behind the princess' back.

A sharp yelp escaped Lucina's lips.

"I'm sorry milady!" the squire exclaimed dumbfounded.

He rode so clumsily he lost balance again and his hand ended on Lucina's saddle, just as the princess was forced to lean forward to pull the other horse's reins harder separating her bottom from her own saddle. It all occurred in a matter of seconds, and before he knew what to look at intentionally, the princess royal bum was close to him: two round cheeks, firm and perky partially hidden by the hem of her skirt. The boy gasped quietly at the revelation, his heart racing in his chest as his face blushed; but Lucina reared back alarmed and nearly knocked the squire off. His horse bucked forward one final time and the boy lunged forward as well, but this time he could stop himself by placing his hands against the plates on the horse's neck.

"Ooof! Ugh…!" Though it hurt, he was okay, and he groaned a bit from hitting his chest on the horse's protective plates ahead that he used to grasp.

"Are you okay?" asked Lucina.

"I think so, thank you milady" he said after breathing heavily, his cheeks darker than pink.

"What happened here?" said a serious voice. Sully was reaching them from the vanguard, having heard the ruckus of the bucking horse. She leered in disapproval at the squire, for she had seen the entire episode as she was galloping towards them. "Oi! Pip-squeak! Is this the first time you ride? You just let this horse buck you all over!"

"I-I…" muttered the boy, but the red-haired fighter wasn't done.

"What are you recruits doing for training? I've seen your swordplay too. Mediocre at best! And now you're telling me you can't ride either? You got to step up your game kid, or you won't last around!" she reprimanded him, her words filled with the discipline only a veteran soldier could have.

"I…" he seemed dismayed and his eyes darted off to the ground. "…yes Lady Sully. I'm sorry. I will train harder."

"Good!" exclaimed Sully abruptly and left for the front of the caravan, but not before staring into Lucina's sky-blue eyes to check if she was okay.

The princess didn't break eye contact, and once Sully was far enough, she let out a sigh of relief. But seeing how the squire looked disheartened, she couldn't help to ask him if he was okay. "Is this your first battle?"

"Y-Yes, Lady Lucina" he admitted, ashamed.

Lucina nodded and tried to find the words to comfort him, but she couldn't really think of anything nice to say to him, so she remained silent for a moment. It was an awkward silence, especially because she wasn't sure if anyone had taken a look at her while she was trying to help him, so it felt good when he spoke again.

"Call me a fool, but I joined the army to impress a girl. The girl I love…" he said and his eyes went off to the distance ahead of him. "Isn't it silly? I wanted to train until I could be her guard, and get closer to her… but I think I've shamed myself now."

"I wouldn't say that." she said, trying to lift his spirits. "You may be just starting, but it's up to you to get better every day. As long as you keep trying hard, I'm sure you can achieve your dreams; to be strong and be with the one you love."

"Well… thank you, thank you for those kind words, lady Lucina." said the squire. "But that's not what I meant. I shamed myself because I'm training to be a knight, an exemplar of virtuous strength… and I just saw a princesses' bare bottom."

Lucina turned to him at such speed that could've snapped her own neck; her eyes opened wide in shock and her mouth half-open, but the squire merely kept seeing the horizon with a slight blush on his cheeks. 'D-Did he? Did he?!' she thought maddened with embarrassment as her face turned red as a tomato.

"S-Sorry. There's nothing to gain for me here, I'm just trying to…" said the boy, but what was he trying to do… or say for that matter? He clearly hadn't thought anything before confessing to her and it was only by his good heart he had done so. "I won't say anything to anyone, please. I just want to continue my path as a knight…"

But the princess was so embarrassed she could die right there on the spot. Did everything she hated had to happen to her?! Just how unlucky could anyone be?! She felt so enraged and ashamed she thought she could rant out at length, scream at the top of her lungs or even have him executed if she felt such an outrage. But in turn, the boy looked awkward and seemed to feel incredibly guilty about the incident, possibly the end of his days as a soldier serving for the Ylisstol army. Lucina's eyes were tightly shut and she squirmed from the humiliation. For now, all she wanted was to get home and reach the comfort of her chambers, where she could safely change her outfit.

"You… will keep this secret remained... or you will be finished. I'll make sure of it." she uttered in a tone more reminiscent of Cynthia's emotional outbursts than her own usual serene voice. The squire shivered so much his entire armor seemed to shake and rattle, and he nodded as fast as he could while his face lost all semblance of blushing, turning paler than paper.

Not completely satisfied with the resolution of the incident, Lucina pressed on and her mare rushed to the front of the caravan at a steady pace; she remained there but still keeping a safe distance from Cynthia and Robin, who kept talking to each other, while the younger princess occasionally pushed her boyfriend on the shoulder in a playful manner and Sully and Frederick led the riders on the front with the aid of the scouts who rode several yards away from the front of the caravan. As the sun hid beyond the horizon on the west, the familiar shape of the castle with its high spires reaching the skies appeared contoured by the beautiful lights of the twilight, and Lucina felt a comforting wave of relief course throughout her body.

---

Half an hour later, Lucina finally got back to the barn with her mare and after checking that she was alone, dismounted without a worry about the flourish of her riding skirt. She exhaled, never imagining she'd be so relieved to put on underwear. She was about to leave for the nearest royal laundry room when she heard a familiar, friendly, and at this moment completely unwelcome voice.

"Lucina, is that you? In Pegasus uniform garb?"

Wondering just how much worse her day could get, she turned to face her friend, a handsome young man with silver hair and a playful smirk on his lips.

"Yes Inigo, I forgot to pack a spare uniform and got drenched in mud. So Cynthia loaned me hers." said Lucina in the most casual tone she was able to mutter.

"I see…well you do look rather dashing."

"Thank you, Inigo"

Lucina had instinctively backed up against the door of the barn, both hands behind her. If there was one man she least wanted to see her bare bottom it was Inigo. Friend or not, he was a notorious skirt chaser and right now she mightn't be desperate enough to take him up on an offer for quick relief.

"Is something wrong?" he asked.

"No, I was just leaving!"

"Oh? And why would a beauty like you be in such a rush?" he wondered playfully.

"Now is really not the time, Inigo. Could you please just let me out?"

Though her words were polite, the skillful warrior sensed the veiled fury of the princess beneath her voice. And he knew better than to piss off King Chrom's firstborn, no matter how attractive she was.

"But of course. Carry on, my lady." he said in a gentlemanly fashion as he bowed before her, leaving her space to exit the stables. 'That's the fire I like in my women. Oh Lucina, you've got more than enough to ignite this heart's burning passion!' he thought excitedly as she passed through.

There was no question about it. He had to check her out, no matter if he was risking his neck on it. As soon as there was a certain distance between him at the entrance of the stables and Lucina walking towards the castle on the paved road, he glanced at her from behind, and what he saw marveled him beyond words. Peeking from the lower end of her skirt, Lucina's bottom was half exposed, her perky and firm cheeks flabbing softly at every step. At first he couldn't believe the precious sight bestowed accidentally upon him, and he blushed furiously at the glorious vision of the princess arse.

But then a soft wind bellowed by and her skirt flapped about and exposed more of it to him. Lucina gasped and brought her hand down to cover herself before turning her head to see Inigo in agape. Possibly seen, no… she knew he had seen it and with blood rushing to her face, she ran pell-mell away, embarrassed till he couldn't see her beyond the castle walls.

He stood there for a while in disbelief for what he saw while wondering why Lucina was without underwear. All the same, it was his lucky day, though maybe momentarily if she decides to have him punished by her father if she ever reports him. He then realized there was a bulging erection growing rapidly on the lower end of his pelvis. Still in disbelief, he tried to cover it as best as he could with both hands before entering hurriedly into the castle, trying to act casual and not draw any attention to himself.

The castle's lobby was crowded with nobles and commoners alike, all of them welcoming the party of soldiers from their expedition, the citizens concerned for the wellbeing of their kin; the highborn curiously expecting to hear the details of the elder princess' accident. Frederick and Sully strode inside leading the line of soldiers followed closely by Cynthia and Robin, and as soon as they entered, a swarm consisting of the heads of the main families, judges and ministers drowned them with questions.

"By Naga! Is it true, lord Frederick? Were you attacked by raiders?" asked a man with a thick white mustache.

"You must have been so scared!" yelped a girl the same age as Cynthia, part of one of the noble families.

"Of course not my dear, she's Princess Cynthia of the Pegasus Knights!" intervened a woman who was obviously her mother, judging by their looks. "Besides, Lord Robin aided them with an entire battalion!"

"Please, please…" began explaining Frederick. "The most important thing is we are all fine. We suffered no casualties, and the raiders were absolutely crushed thanks to the timely intervention of our tactician."

"But what about Princess Lucina? Is it true?" continued the young noble.

"Did she really get hurt?"

"I'm sure we can talk about it later. We've all had a really long day…" said Robin in a calming manner, but the nobles were distracted by something behind his back.

Lucina had just entered through the front gate of the castle, brooding over her unlucky circumstances earlier and as soon as they set eyes on her, the nobles and magistrates flocked towards her and began asking questions all at the same time. "Are you alright, Princess?"

"Is it true you were unconscious?"

"The raiders must have been terrifying! I was praying to Naga the entire time!"

"There's no way the raiders could have defeated Chrom's daughter! The blood of the Hero-King flows strong in their veins!"

But Lucina couldn't deal with them, even less after going through the entire day being overly careful so no one would take any suspicion of her and her attire. She took a lock of hair and made a gesture to place it behind her ear so it would cover he bruise on the side of her forehead, but still tried to remain formal and polite in front of the inhabitants of the royal castle.

"Please, my lords and ladies, it's been a really long day…" she said, pressing her legs together in an attempt to maintain her skirt low, embarrassed to even think what would occur if anyone found out she was without any undergarment.

"But…!"

"If you'll excuse me, please…" she murmured as she bypassed the cluster of people that blocked the way to the grand staircase.

"Really, it's always hard to talk after such a battle." said Cynthia in a surprisingly concerned voice standing between her sister and the number of people who overcrowded the lobby.

"I think we could all use some rest" said Robin in a comforting voice, and Frederick nodded signaling he agreed with him. "I'm sure we can all talk about the incident in the morning after a good night's sleep. Let her pass, everyone. Clear her way!" he added, and the people dispersed back to the main hall where diner was about to be served guided by Cynthia.

"I…T-Thank you Robin… you didn't have to do that…" said Lucina shyly now that everyone was away. They stood at the foot of the staircase, where the stained glass let the dying lights of the evening in.

"It's no problem." said Robin merrily. "We're almost kin after all now, remember?" he said with one of his typical gentle smiles. "Just take the rest of the day off. If there's someone who needs to take a break, it should be you."

It was as if he was doing it on purpose just to trick her as Cynthia had teased her non-stop for the last couple of days! Acting all charming and caring for her was more than enough to make her heart race inside her chest, and light a fire that burned inside of her rather sooner than later. "Thank you, I… It means a lot." she said, grateful, feeling a warm sensation stemming from her chest all throughout her body. She waved goodbye and climbed the first steps of the staircase.

Robin stood there seeing her leave up the stairs, and his heart skipped a beat when he realized. Although accidentally, the Pegasus Knight skirt was so short, he couldn't help but gaze upon Lucina's perky bottom! Her cheeks were smaller than Cynthia's but they seemed firm and round, and it was completely bare! A combination of dread and wonder filled his senses, but he couldn't look away and couldn't even move, awestruck at the sight of the princess' glorious bottom. His face was turning increasingly redder by the second. And this is how his girlfriend found him when she returned to the lobby after dispatching the nobles to the dining room, but Robin was so stunned he didn't realize she was there until she snapped her fingers in front of him, causing him to blink owlishly as he came back to his senses.

"You alright? Is Lucy okay?" she asked, seeing how he seemed petrified.

"S-She…well…I…" stammered Robin, unsure of what to say, but the second a mischievous grin appeared on Cynthia's lips, he knew she had pieced things together.

"Oh…so you know…" she said delightedly.

"I…it was an accident I swear!" he replied in an apologetic tone. But the gears in his brain were already turning at full speed. So this was the reason Lucina was having so much trouble focusing on their ride back home. Was she maybe without her underwear for the entire journey? Was this the reason she struck her head? And how could Cynthia know? "But hold on, how do you know?"

"Huh?! Me?! Well…" but it was too difficult for Cynthia to find the right words to tell what had happened. If it hadn't been for her incessant teasing Lucina would have been perfectly fine, and it still weighed on her conscience the fact that her older sister had ended up hurt because of her own actions. "It's a little complicated Robin…"

"Oh…" he knew he had to take things seriously when she called him by his name and not by any of the playful nicknames she had for him. He stepped closer and grabbed her hand. "You know you can tell me anything, Cynthia. I'm not one to judge."

Cynthia took a deep breath before responding, not sure of how her boyfriend would react. "Well…Lucina knows about us Robin. And I don't mean she knows we're together. Everybody knows… but she's actually seen us. As in… fool around in the library... and the stables… aaaaaaaand ummm… I've been teasing her a bit, just for fun! But I didn't mean to harm her!"

"H-Hold on…" stammered Robin, absolutely shocked as his face turned the reddest Cynthia had ever seen. "Cynthia, are you serious!? Why would you do something like that!?"

"Hush! Don't speak so loud!" begged Cynthia pulling him closer to the archway that stood between the lobby and the staircase. "Please Robin, I never meant for her to get hurt! It was just a silly game! Can we talk about this later?"

Robin didn't feel horrified at her actions. Knowing Cynthia, he knew she only tried to play a cat and mouse game with her sister, but he was utterly surprised to see how far she could take it. Unsure of how to react he stared into Cynthia's grey eyes, and he saw only regret in them. But before he could say anything, the loud steps of a soldier's boots hitting the stone floor made them both turn their heads to see Sully striding towards them with a severe expression on her face.

"Cynthia, a word?" she said, and without waiting for a response and not caring about Robin being there, she let out all of her thoughts plainly. "I know there's something going on between you and your sister. You two are always competing for something, and to be frank, I don't really care what. Robin, I really hope you're not caught in the middle of all of this." she said.

The tactician felt butterflies flapping around in his stomach. The suspicion rises in Sully and he'd been too distracted to think of her. He felt he underestimated her.

"It's none of my business, and I don't really care about your personal problems. Just one thing; keep it to your damn selves. Lucina must be completely focused the next time there's trouble. I can tell she's all a mess right now."

"Please Sully, I'm sure we can-" began Robin, but Sully cut him off with her hand up.

"…I'm off to report to Chrom. I'll see you two later."

The two lovers remained at the feet of the staircase, seeing her walk away towards the royal chambers, and they could only turn and peer into each other's faces unsure of what to say or what to do next.

---

Lucina walked the castle corridors as fast as she could, making sure nobody was following her as she trekked all the way back to the safety of her quarters. Every time she turned a corner, she peered her head over the edge to be sure nobody was around. And when she walked, she pulled the lower end of her tiny skirt so her bare bottom wouldn't be exposed, and the thought of it was mortifying her every step.

"Please don't let it be Father! Please don't let it be Father!" she said to herself desperate when she heard a rustling of voices as she approached the corner of the hallway. The soft echo of male voices indicated that a small crowd was on the next corridor, and she waited; hidden on the other side of the corner until silence reigned in the hallway before venturing there where she saw a group of ministers and nobles walking down on the other end of the hallway. The shivering princess had to walk their way, nervous, almost shaking until she reached the door to her room. And once inside, the first thing she did was run straight to the bathroom and remove Cynthia's godforsaken Pegasus Knight uniform to put back on her usual blue tunic, that she had really grown to miss over the course of the day.

She sat on a comfortable couch back in her bedroom and reflected on all the terrible moments she had endured in the last hours. Not only had Cynthia flaunted and taunted her without mercy, but she had even done it in the open where anyone could've seen! The way she bounced her thick arse, slapping it wildly against the hard leather of her saddle was enough to send the shivers down Lucina's spine. How could she be like that? How could anyone behave as such simply for the sake of having fun, or teasing? Cynthia definitely had to be crazy, and yet, so bold that jealousy was growing inside Lucina's heart. But she just couldn't do that, or be like her younger sister, the elder princess had a more reserved personality, and though she was well liked by everyone, she'd certainly never gather the courage or boldness to do something that dangerous for her reputation and image as the King's firstborn merely for the sake of fun… no matter how tortuous it felt for her to be on the receiving end, and how much she craved the perversion her sister brought.

Lucina shook her head, unsure of herself. The princess felt she was losing herself more and more to this perversion of fantasy by watching her sister and longed to enjoy the pleasures of the flesh she had shown her… but at the same time, she felt she couldn't just submit to her desire and discard everything she knew about behavior and reputation. At least, not how she was at the moment, no matter how much she really craved it as evidenced by the warm fuzzy feeling stemming from between her legs that hadn't stopped intensifying as she climbed the stairs back to her room.

When she felt her skin turn hot for Robin, it became almost impossibly difficult for her to approach him, or even acknowledge him without acting so nervous she would even stutter, a very uncharacteristic trait in such a determined and courageous warrior, and she even had increasing difficulty sleeping without dreaming about him. And when her heartbeats raised because of Cynthia, the images of the voluptuous curves of her naked body came rushing to her mind, and she remembered the soft touch of her enormous breasts, how savagely her buttocks jiggled on top of the horse, or how naughty her facial expression was every time Robin thrust his rod inside of her it was easy to see why the elder princess was losing her mind wishing to experience carnal pleasure all by herself. Even thinking about all of this was enough to get a soft buzz going around her body, but she was too tired to even think about acting out on impulse.

Though her feelings seemed opposite, they all made a heavy burden on the princess' heart. Just what had she gotten herself into?!

After an hour passed, Lucina stood up to grab a small mirror that rested on her wooden vanity table and took a look at her reflection. She looked mostly fine, though there were small bags under her eyes, and the little piece of bandage that covered the side of her forehead remained hidden behind a lock of blue hair, thankfully. "So no one noticed it… thank heavens…" sighed the princess, rubbing the area softly to feel a tiny bump there and a stinging pain. She took a small bottle of lotion and applied it on the bruised area of her forehead before placing the bandage again when she heard the door creaking as it opened. Apparently, Cynthia allowed herself in without even knocking first.

"How are you doing Sis?" she asked casually, as if stepping into the middle of a tea party.

Lucina didn't even know where to begin. "How am I doing? HOW AM I DOING?!" she exclaimed, losing all composure. "Do you have any idea how difficult it was for me to get back? I had to avoid everyone, Cynthia! And it's not fun walking around the castle without undergarments!" She glared at her knowing she was responsible for not packing a spare for her at the lake.

"Hehe... uhh… sorry?" Cynthia giggled nervously upon the realization. She then went back to tease her for the umpteenth time. "Well, I think it's really fun! Such a thrill to be in total risk at all times! But hey, Robin doesn't like it either… at least until I come up to him and-"

"Stop! I'm serious, Cynthia!" yelled Lucina, completely blushed. "It was mortifying! I had to keep pulling the skirt down every step of the way, and I'm not even sure that really did the trick!"

"Huh?" mumbled Cynthia, who seemed much more interested in the folded clothes that made up her Pegasus Knight uniform.

"The castle grounds are full of people, you know?" argued Lucina both enraged and embarrassed. "There was no way to ensure my safe trek home without worry! Now I've already been exposed to TWO people I encountered on our way back!"

"Well… three if you count Robin." she said mindlessly, as she pressed on the skirt of the uniform, eager to get rid of all the wrinkles on the cloth.

"R-Robin?! Gah! Robin saw me too?!" if her face was blushed before, it certainly seemed about to explode now.

"Mmhm!" muttered her younger sister, nodding with her eyes closed. "Just as you were going up the stairs." She added with a smile.

"I-I…I…" stuttered the elder princess. Lucina felt like dying of embarrassment. Despite secretly wanting Robin to notice her just as he noticed Cynthia, she didn't really want it to happen… or did she? "I could just die now…" she replied at last with a gasp of defeat.

"I think Robin liked seeing them, along with mine." teased Cynthia with one of her mischievous smiles, obviously referring to both princesses bare bottom. She giggled at her own perversion, and Lucina shut her eyes trying to turn her head away, but the images of Cynthia's huge butt shaking the cheeks up and down came rushing to her mind and she had to gulp hard.

"I still can't believe you flaunted like that out in the open…" sighed a dismayed Lucina, her eyes hidden under long locks of blue hair.

"I can't believe you were staring at my boingy bits during the ride. You must really like them, as much as you like seeing my big bouncing booty, just like Robin does."

The elder sister was about to argue back, but she didn't quite understand what Cynthia was referring to. "Boingy bits?"

"Yeah. I got that from Nowi. She claims mine are just like Tharja's." she replied.

Tharja? What did she have to do with all this? The only time Tharja had come up into the situation was when they talked about who had the biggest breast size among the female members of the army… and Lucina recalled Cynthia's enormous mounds boinging up and down when the sisters were galloping, prompting her skin to blush furiously once more. "I-I'm sorry…" apologized Lucina, who was about to die from the embarrassment.

"Hey, no worries, Lu. It's fine," simply smiled Cynthia.

"No, it's not fine at all!" insisted Lucina. "I know I haven't been myself lately. I don't know what's gotten into me… It's like a fire I just can't put out! And it's consuming me all over…"

"Well, you've certainly been distracted an awful lot…" agreed Cynthia. She then bounced her two mounds to point out, "You've been so stressed about these two, you didn't even notice the branch that hit your head, did you?"

"Branch?!" let out poor Lucina. "There were soldiers around! What are they going to think about me now? About their leader?"

"Don't worry Lu, they've all seen how hard you train." said Cynthia in a comforting tone. "You wouldn't be the first knight to fall off their horse out of exhaustion. And I saved your skin by telling them how hard it's been for you to rest after the training spars and exercises. They might even give you a break soon!"

"Well… that's true…" conceded the elder princess. Lucina could comply with the narrative, after all she had a rough time every night when she went to bed, but for reasons she hoped Cynthia hadn't found out. The only thing she could agree with Cindy was the thought of her huge and soft breasts had haunted her dreams recently. "I haven't been sleeping much as of late."

"How come?" wondered Cynthia instantly amused, peering into her sky-blue eyes, but Lucina shuddered and looked away, but she found her sister's face everywhere she looked and ended up shaking her head even harder, this time shutting her eyelids close. "Is it about what we did last night?" wondered the younger princess as she smirked, and when she heard her words, the only thing Lucina could do was bury her face in her palms with a sigh of defeat. But Cynthia rubbed her upper back slowly, in a comforting way. "Lu, It's okay… don't shut yourself out. Nothing good can come out of it."

"It's not okay! What we're doing is forbidden under Naga's eyes…" Lucina complained, finally looking at her sister's face. "And I haven't been acting the same since. I'm sloppy. I'm distracted… and it's taking a toll on me. Can't you see? It's like I'm losing myself, falling deeper and deeper… and there is no end to it."

"Well… that's just the more reason to tackle the issue as we should!" exclaimed a surprisingly diligent Cynthia.

"I don't know, Cynthia. I don't feel so sure." replied Lucina awkwardly, and her eyes darted to the richly decorated carpet that covered the floor of her room. "More training? I'm not really sure that's going to cut it. I'm starting to think it's risky. And I don't just mean we could get caught… it's like a fire burning up inside of me and… I don't want to be consumed by it. Or you…"

Though the words Lucina had just pronounced did more to fuel Cynthia's lust than putting it out, the younger princess relished only on the inside, being careful not to show explicitly how pleasant and thrilling she found Lucina's struggles. "Well I've got an idea of what to do."

Someone knocked on the door, prompting a loud gasp from Lucina's mouth. "Oh please don't let it be Father! I just can't talk to him right now!" begged the elder princess.

"It's not father…" said Cynthia as she went for the door. From Lucina's point of view, all she could see was Cynthia and her thick bottom peeking at her while she snuck her head out of the gap between the door and the frame, and exchanged a couple of whispered words with the person on the other side before fully opening the door.

And just like that, the King's tactician entered the princess bedroom, dressed in a casual yet adequate tunic of a brown shade, and a typical cotton shirt underneath. Robin looked much more relaxed after washing himself and brushing his snow-white hair, and Lucina detected the faint scent of blueberries when he closed the distance between them to greet her. The older princess felt butterflies flying erratically inside her stomach, and her heart raced in her chest as all of her thoughts became one single jumbled mess.

"R-Robin! What is he doing here?" questioned Lucina, surprised, her eyes wide open.

"Well I just had this teeny, tiny idea bursting in my mind…" teased the younger sister, holding her boyfriend's and sister's hands as a devilish grin appeared on her lips and a faint pink blushed her cheeks. Lucina could only dread…

---

Now that he had returned to the comfort of the castle, Robin thought he could finally find some alone time with his girlfriend, who had been teasing him non-stop the entire journey. Now they were sitting in his quarters as the dying lights of the evening entered through the wide window panels in the chamber, which was located on the lowest level of the castle in a chamber quite distant from the main hall and the rest of the most crowded areas, and instead close to the library. And the idea Cynthia presented him was wild, to say the least.

"I just needed to assert that if I am sharing this, any woman or man understands I am the alpha female" she let out, admiring the blush on Robin's face before switching to a more serious tone. "I also think Lucy has forever been too prudish and needs to awaken a bit. I think she's always felt the need to be strong, proud, powerful, and a badass princess, which she is. But I also think the weight of the crown hurts her ability to be a normal girl and do fun things like have imaginary adventures, go to plays, eat cake without worrying if the frosting got on the tip of her nose, and fall in love with a wonderful guy. You know? The whimsical stuff, the Grima of our world, destroyed and replaced with darkness, decay, despair, and death."

Robin could do nothing but nod in agreement. But Cynthia still hadn't finished.

"I love Lucina, Robin. I love her even more than I love you or my parents. She always made sure I had enough to eat, that my tent never let in rain, that my blankets kept me warm even if it meant she had to go to bed cold, wet, and hungry" she said, though it was odd to hear her use such a serious tone. "I know that falling in love isn't a matter of life or death in the same way, but I don't want her to be broken-hearted and alone because she lacks the tools to let loose. Are you still gonna help me Robin? We don't have to actually do it in front of her, but I would like to show her us doing some stuff."

"Cynthia, when was the last time we kept our hands off each other successfully?" he simply replied with a warm smile.

"That's true, but still! Will you-"

"Of course, Cindy. You're my naughty pega-pony princess."

Cynthia smiled greatly and hugged Robin tight.

---

So now that Lucina had heard the insane proposition her sister had made, she felt both shocked and jarred. Sharing her boyfriend with someone? Cynthia had just lost her wits, she had to. What sort of sane couple would do that? It would become a harem! And not only did it mean falling from Naga's blessing grace, but it would cause an absolute scandal in the castle if anybody found out or even took a hint at what they were doing. The name of the royal family would be tarnished, maybe for generations, as depraved!

"C-Cynthia! N-Now you've lost it, you've really lost it!" she exclaimed as tears of shame and embarrassment rushed to her eyes and didn't go unnoticed by Robin the second she turned her head to him. "Robin, I'm really sorry. I have to apologize for dragging you into this. Cynthia doesn't always have the best of ideas… I swear to you, I don't really know what she's thinking. I have nothing to do with it, I swear!"

Lucina made an attempt to storm out of her bedroom and lock herself in the private bathroom, but her sister stopped her by placing her hand on Lucina's chest. "He's fine with it." meowed Cynthia with her usual cat-like, devilish smirk.

"F… Fine? FINE?!" let out Lucina, astounded. "How can he be fine with this? What you're suggesting is strictly forbidden! And it would cause an uproar in the castle! Can't you see? This is madness!"

"May I have the floor?" joked Robin with a tiny smile. There was a soothing quality in his voice, every time he spoke everyone around him seemed to understand each other better. "Cynthia has told me about your struggles, Lucina. Everyone should have the right to relieve themselves instead of bottling up all of our passions and needs. You are a hero to the nation of Ylisse, a legend for aiding in Grima's defeat and the princess of the halidom. But you're human too; a woman, who can feel the urges of the body just like anybody else. And there's nothing wrong with that. Truly. I'm just here to help."

"H-Help?!" the skin on Lucina's face seemed even redder than her own blood, and the tears were on the verge of falling down on her cheeks. This was the most embarrassing she had ever felt in her entire life. How could she have allowed things to escalate to this point? "Sharing isn't a necessity, Robin. This is just wrong…"

"Ahem, I don't think I've made this clear…" intervened Cynthia in a clever manner, prompting Lucina to take a step back. "I can't see you getting all fuzzy over us. It was fun at first but now I think you ought to let out some steam, Sis. I just want you to watch us… at least for now" she added with a mischievous wink of her eye.

"W-Watch?!" The tone Lucina used was much louder than she had anticipated and she covered her mouth in shock.

"Yeah!" cried Cynthia.

"That way, when you are comfortable and ready, you can join us later." Robin chimed in.

"This is your chance, Lucy!" Cynthia added enthusiastically. "Time to get some experience and have some fun! You're always working so hard and stressed, so you deserve that break I mentioned. So why not have us make you feel really, really good?"

'Things would only turn for the worse. It's not like last night when Cynthia barged in and… we practiced a bit. Robin is here!' she thought desperately, backing against the wall unsure of what to say. 'And now they're giving me their full consent to watch? Just how can they be willingly okay with this just for me? This is just maddening!'

Her heel finally touched the wall, and she realized she was literally cornered now. The elder princess' eyes drifted left and right, Robin and Cynthia respectively, as she swallowed heavily not knowing what to do. Her common sense kept screaming no, that it was against everything she was brought up to believe and think as righteous or morally correct, enticing her to follow the right path. But Lucina realized the more this voice resonated inside of her head, the more she wanted to silence it once and for all, and let go of all her inhibitions. Both Cynthia and Robin looked beautiful and attractive, and the smiles on their faces seemed as honest as their intentions, intensifying the poundings of Lucina's heart hammering inside her chest.

"I-I don't know…"

"Welp, me and Robin are going on ahead at any rate! You know what to do." Cynthia declared.

The words felt coming from another mouth, but Lucina heard her own voice say them and Cynthia's smile turned into a wide grin. She stepped closer to her boyfriend and caressed his chest for a moment before diving into his lips unexpectedly, finally releasing all the tension that had filled the room. Taken off-guard, Robin couldn't help but to applaud his girlfriend for her brazen nature and devious plans. It was clear that she was planning on being as loud and vulgar as possible in order to entice her sister to join in. Already she was moaning and slurping, licking her lips and breathing as heavily as she could without coming across as exaggerating - this was how she usually sounded after considerably more foreplay than this.

The white-haired tactician could feel Cynthia's large bust pushing against his chest, the soft mounds grinding up and down his body in a way that quickly prepared his penis to rise to the occasion. This fact that did not escape the younger woman's notice, and she smirked at him, bringing her sex to his for added pressure. The clothes were quickly becoming a hindrance.

They got friskier with each other by the second as they slowly undressed one another, though more aggressively than needed in order to entice Lucina. Robin went first when he groped Cindy's bust while kissing, making her yelp and moan at his rough touch just as she liked it while he squeezed the mound tighter and tighter. Parting lips for a moment as Cynthia pants, Robin then moved his hands to the blouse's edges where her buttons were, grabbed both and ripped her top asunder. Cynthia exhaled at the rough action as buttons popped and flew out of place, thus exposing her sky blue bra with a bouncing motion of her breasts from the swift move Robin made on her. Cynthia blushed immensely at his increasing lust, but not as much as Lucina. She stood frozen in place. The thought of leaving was far from her mind, Robin could tell that much at a glance, and she held her hand in front of the bottom part of her face as she breathed with a half-open mouth.

Cynthia let Robin undress her blouse and toss it aside while she removed her thigh high boots, and he marveled at Cynthia's lingerie; skimpy sky blue panties and bra to match. Robin was distracted to see Cynthia approach him and with the same strength as Robin could, used her nails to dig in Robin's shirt and rip it apart as much as possible, revealing the tight muscles of his chest and abdomen. At a gasp, he sees her sexy smirk and blushed as he could feel his blood rushing towards his crotch. She was so into this with such lust, and it was contagious. Allowing her to remove the shirt and toss it aside as well, they resumed their sloppy make out session, but this time their tongues wrestled in a slushy manner.

As the two lovers parted from yet another wet, messy kiss, Cynthia licked her lips and then whispered so quietly that Lucina couldn't hear them. "Grab my ass, Robin. I want to get really raunchy and get Lucy on board." she commanded, removing his coat from his shoulders and kissing the newly exposed areas.

Doing as he was told, he brought his hands down to the gigantic ass and began kneading the cheeks, his hands all but sinking into them. The added pressure from behind pressed her pussy even harder against his erection, which brought a genuine, satisfied groan from Cynthia as she had to distance herself from worshipping his body and collect herself.

Robin, however, didn't want to give her a chance to recuperate, opting to instead push harder and make sure that she felt the full size of his cock pressing against her crotch, even if it was still concealed by his pants. The young Pegasus Knight let out a sharp yelp and leaned back, keeping herself standing only by wrapping her arms around his neck.

"Aaah, aaah...!" She moaned softly, biting her lower lip with closed eyes. "Oooh, I can already tell how hard you are, Robin! Does my big booty turn you on that much?"

He answered only by spanking her buttocks hard, eliciting sharp cries of pleasure from the princess and a loud slapping sound every time his palm bounced against her soft cheeks. His passion took a hold of him as he grabbed and began squeezing her rear harder thus wringing soft moans from her. It felt like massaging a pair of enormous, smooth sandbags, or at least that's the closest parallel Robin could think of. However, the panties, no matter how much they had disappeared between the cheeks, he found that they were getting in the way, and thus began playing with them by the hem, slowly lowering them, showing more and more of her already partially exposed ass. Bouncing it and such and giving it pats and soft spanks, causing the two of them to giggle and laugh in enjoyment.

At this point Lucina's face was staring longingly at them, enthralled by the sight. Her lower lips trembling as she rubbed her thighs together, she even looked as though she wanted to join in on the fun already, but had no idea of how to even get their attention. While Robin saw this out of the corner of his eye, he figured it was time to really win her over.

He then grabbed the hem of Cynthia's panties and lowered them all the way down her thighs and let it drop down to her feet, though he kept her thigh high socks on. Robin's craving intensified as his palms slid up the back of her thighs until they reached her tush once again for more massaging. But Cynthia's craving was just as intense as Robin's, and she didn't simply stay put waiting for him to join her body with hers. Instead, the younger princess dropped to her knees and went straight for her boyfriend's crotch, undoing his pants and unleashing his massive thick cock. Upon it springing upward and twitching the second it was freed from his undergarments earned him a surprised gasp from Lucina and a hungry look from Cynthia, who licked her lips and soon began stroking it with slow careful movements. When she felt it was at its hardest, she spat on it to wet and moisten it up before beginning to stroke it faster and faster as Robin groaned and panted, pleased.

"Haah... Cindy..."

As Cynthia cooed seductively, Robin felt thick fluid drip from the tip of his cock and the princess wasn't going to let any of it go to waste. Their gazes met when she looked up at him, and she smiled devilishly before opening her mouth and covering the entirety of his glans with her lips, playfully caressing everything inside with her tongue. When she began sucking, Robin felt he was about to melt inside her mouth and had to struggle not to bust his load inside, so pleasant was Cynthia's skill.

Lucina scrutinizes and now could only get as turned on as Robin by seeing how Cynthia was blowing him with great interest. She even notices how much her boobies bobbed forward gently in the air as she thrusts herself all the way down Robin's shaft. She dreads how it couldn't get any more crazier… could it?

Robin moaned loudly and Cynthia opened one of her eyes and stared at Lucina, whose face was already so red, she looked feverish. But the younger princess maintained eye contact with her, and Lucina's breath only turned agitated as she felt a wet and hot sensation between her legs.

"Oohh... Cynthia..." moaned Robin faintly.

Cynthia was still wearing her bra and she meant to undo the knot at her back to remove it, but Robin felt way too impatient for that. He needed to feel her velvety skin around his rod. So he slid his penis away as it popped out of her mouth. 'Gahh…!' she exhaled and panted as Robin went underneath the front strap of the brassiere and tucked it between her bosoms. By instinct, Cynthia pressed her breasts around his cock, and a warm gentle pressure of her skin prompted another panting noise from Robin, who began pushing softly against her softness while she pushed in the opposite direction.

'She's... Squeezing him with her breasts! It looks unbelievable...' thought Lucina, who wished to be squeezed softly between her sister's huge breasts. She gulped and squirmed in place, unsure of what to do next. 'Mine aren't nearly as big... Would I be able to do the same?'

A flash of inspiration or uncontrollable desire suddenly struck him as he stood up and without warning, he bent down and grabbed Cynthia by the back of her legs and lifted her upside down, holding onto her legs while both of their stomachs were in contact with the other, so they could both use their mouths to please the other. Robin's tongue began licking Cynthia's pussy thoroughly, at first on the outer labia but soon caressing and massaging the upper part where her clitoris was, eliciting loud moans from the princess who had her mouth stuffed with his thick cock. Both moaned in muffles as they continued licking and sucking each other, Cynthia's warm juices dripping from the corner of Robin's lips. She presses her boobs hard on his abdomen as she deepthroats until she gags.

Agape at the action, it became so tortuous for Lucy to stand idly and watch, but she had no idea how to react. Her crotch turned wetter and she felt she was burning inside, and all she could do was rub her thighs furiously and grind her teeth on her knuckles, enthralled.

'I... I can't believe this...' thought Lucina incoherently. 'She's sucking on him upside down! …Harder too! And her mouth is all stuffed… It sounds so wet... And... I-I'm feeling wet too!'

Every time Cynthia gagged and popped his cock out of her mouth, it twitched upward and uncontrollably, dripping wet with the younger princess' spit and its own masculine juices, which allured Lucina to no end. Her heart hammered on the sides of her head, and her mouth was overflowing with saliva as well, fantasizing of stuffing her mouth with Robin's member, tasting and swallowing all that could come from it. Her thumb was grinding against her teeth, and without realizing, she began sucking on it as if it was his thick cock. She licked and covered the tip of her thumb with her lips lasciviously at the same rhythm Cynthia was pleasing Robin, bobbing up and down with suction noises and humming.

"Mhh! Mhh! Mhh! Mmph! Mmph!"

"Uwaah… huwaah…"

The tactician's lips smacked from the princess' vulva, and he dug his nose deeper and shook it left and right his tongue massaging everything in its way, even smelling her natural scent, eliciting sharp moans from Cynthia who shook softly, her booty jiggles in the air. He was as addicted to her as she was to his rod, but he needed a little break from holding Cynthia during the entire session. His cock slid out of her mouth as she exhaled hard from it as the cock springed upward in another twitch.

Lifting up Cynthia by putting his forearms under her back and rear, he flipped her upward and carried her over to her large, luxurious bed and threw her down upon it. He then ripped off her bra and freed her huge bouncing bust. He stepped to the side so that Lucina could see them.

Besides how short their skirts were, that was his favorite part of the Pegasus Knight uniform. She welcomed him with a laugh, raising her arms over her head and showing off the full glory of her naked form, her pride apparent. While she had undoubtedly inherited some very nice assets from her mother, a lot of hard work had gone into getting into the shape she was now. Sure, it had been a necessity and not because she had been desperate to look good, but that training had definitely yielded a nice bonus reward as evidenced by the thickness of her thighs, her curvaceous hips and yet feminine but powerful legs.

Lucina could only stare at her beauty and attractive appearance seeing her display herself with great interest. She just wasn't sure if she could do such herself, but perhaps for Robin would be an exception. Yet now, her body looked inviting, even to her and she couldn't take her eyes off how much her breasts were sticking up in the air as she stretched herself with her arms above her head. How divine has Naga granted women to become?

Admiring his girlfriend immensely, he started leaning down, kissed her stomach and the area between her breasts, the scent of lavender intoxicating as always. He soon met her lips again in an eager kiss, and then he stroked back a few strands of her hair while he kept kneading her enormous mounds of velvety skin until her nipples were fully erect. He then stood up so his cock was within reach.

Grabbing it with one hand, Cynthia positioned him to her side and stroked his shaft against one of her breasts, pushing into her soft flesh and rubbing it all over. She yanked it about with a firm grip and began swinging it up and down for her amusement and brought it down hard on her breast, slapping it against it and watched as her breast ripple upon contact. She giggled immensely at the sight before rubbing it all over her huge mound. Once his glans rubbed against her pink, erect nipple, her face contorted in pleasure and she sucked in her lips, breathing heavily as the incredibly sensitive area was being caressed.

"Oooohhhh yeaaaaah..." she murmured to herself, totally absorbed into such naughty display, she and Robin could hear Lucina's heavy pants as she turned her head to look at her sister who was looking like she was at the breaking point, rubbing her thighs together while remaining frozen in place, her face the reddest she had ever seen. 'Lucy... c'mere.'

For the first time in several minutes, Lucina moved, walking towards the bed where her sister was currently on the cusp of fucking her boyfriend right in front of her. She said nothing, but merely stared wide-eyed at the whole spectacle. Cynthia kept staring with a meek smile, gaining all of Lucina's interest and yet she was still hesitating from doing what she really wanted. All she ever needed was a little push, one that could only come from her own specialty: teasing her. "Come on, Lucy, touch them…" she whispered, grabbing her other tit, squeezing it and waving it around for her. "You know you want tooooo..." she sang teasingly.

Seeing how her big breast was shaking, how erect her nipple was, Lucina just couldn't let it slide from her opportunity. She was finally about to touch it, what she yearned for since this morning, since last night! Standing still for a few seconds before finally sitting down on the edge of the bed, Lucina gulped, needing little persuasion at this point. Raising her trembling hands, at long last, her palms made contact, cupping the huge mound with one hand. Lucina exhaled at the soft touch, incredible how soft it felt, bare and free from the garb, it was magnificent. Her mouth was agape, her cheeks flushed pink immensely, holding such a beautiful and seductive part of her sister's body in her hand that depicted women's best attractive attributes relieved all her tension and anticipation for so long.

"I feel like... I could die happy..." she whispered.

"Luce..."

Lucina gasped from being snapped out of trance for a moment, looking at Cynthia in embarrassed panic. "Ah-Huh?"

"Take care of my boob, would ya?" she asked with a grin. "I can't stand one getting all the attention and not the other! Messes with my sense of symmetry."

Silent for a moment, trying to process the request, she nodded. "O-Okay" she kept her hand on, cupping the huge mound with one hand and trying to think how she could please it. With her other hand, she gently stroked the nipple. "L-Like this?" Her movements were a bit stale and careful, as it would be the case with any other debutante, but they were loving and curious.

Nodding, Cynthia pushed her head hard against the soft mattress as both of her tits were being tended to. "Mm, yeah, just like that. Aaah, I love you both, haaah! Aaah, my boobies feel so good..." She said, the latter part just a quiet murmur to herself.

The younger princess squirmed under the loving affection of her two partners, biting down on her index finger. Robin laughed lightly at how his girlfriend was reacting to their attention. He turned and saw Lucina maintaining her gaze on the large, cushiony mound in her hand, treating it delicately yet firmly simultaneously. Her concentration was such that Robin couldn't figure out if she was just feeling embarrassed and ignored him, or simply found her sister's impressive bust so fascinating. He smiled in amusement, wondering how she could abstract herself and focus intensely on the task at hand, and Cynthia continued stroking his cock against her boob more aggressively.

"Ahhh... Mmh..." Cynthia purred contently. "Haaah... You're both so sweet... But now it's time to step things up a notch."

Lucina stopped for a moment and looked at her sister with curiosity, 'Ah? W-What do you mean?'

"Switch places, you two" Cynthia commanded the two with a grin.

Confused, Lucy and Robin looked at each other perplexed, but they complied as Cynthia let go of his rod. The two of them stood up and walked around Cynthia's hanging legs. Lucina could only stare in awe as she watches his penis swing and twitch from the walking, causing her to gulp hard at the sight, making her face turn so hot.

"N-Now what?" Lucina then asked with a shaking voice of nervousness.

Then Cynthia ordered, looking at them both, her voice playful yet carrying the tone of a princess' command. "Now suck on my tits."

Lucina gasped softly and still red hot, she doubted it could get any hotter but she felt a heat rising from the bottom of her toes to the top of her head. The coursing sensation of tingliness had evolved into a much more intense feeling of both nervousness and desire she felt all over her skin; and to top everything off, now she got the perfect opportunity to fulfill her imaginary fantasies. Yet she still didn't understand one detail.

"W-Why then... did y-you...?"

"One is a bit sticky from Robin's cock, and I think you'd find that much more delicious than Robin."

Another gasp but harder; yet, she felt hotter than magma at the thought and the sensation of overbearing lust seemed to reach a new level as she felt her crotch turn slightly wet. Thankful for the consideration, Robin merely laughed, but Lucina swallowed heavily. She was nervous, but far too curious and aroused to offer any genuine objection; she wanted to see where this would lead, and to experience all the things Cynthia had told her about.

Needing no further instructions, Robin sat on the bed and began kissing Cynthia's breast, starting by kissing the top and the sides, part of his face burying itself in the velvety flesh. The scent and touch were enough to really get him going, but he was further rewarded by one of his lover's cute, excited giggles. Once his lips moved to her nipples, her laughter turned to moans. Lucina watched enamored and then turned to her sister's other bust, covered with slick from Robin's cock. It was going to be like tasting two desiring meals she craved since the beginning, the realization of all of her steamy desires ever since she had caught them at it.

Starting slowly, Lucina was more careful, but quickly got into the swing of things once she heard her sister's pants of satisfaction. She lowered her head towards it and worked in tandem with the tactician to lick around her cleavage until she reached her areola. She then began to plant soft kisses around it, slowly until she reached the Pegasus Knight's pink, puffy nipples and kissed the tip a couple of times. Entranced by her actions and the soft texture of her sister's nipple, she now desired the steamiest task of all. Breathing in anticipation again, she opened her mouth over her equally pink areola and started sucking on it, enveloping it with her wet, warm tongue. 'It finally came to be...' She thought.

The periodic, quiet moans cascaded into a consistent stream of blissful screams and panting. Cynthia's legs in particular tensed up and dug deep into the mattress as she tossed and turned her head to the sides, finding no outlet for the energy and tension building up inside of her body. Tasting the young princess' nipple, Robin sucked on it hard, tugging at the breast with his mouth until he lost the grip, producing a large smack, letting it bounce about, and then dived down again to repeat the process. Lucina, on the other hand, was much sweeter, and was more content using her tongue and sucking on the other nipple as though it was a rare sweet, saliva dripping from her mouth down along the huge mound, coating it in a wet sheen.

Opening her one eye, she watched how Robin continued his hard suck and letting go of the large breast in a bouncing effect. It became mesmerizing to see it play it over and over, she stared at it a little longer before closing her trembling eyes and proceeded to suck on the other breast. She snuggled her mouth over it and even moaned in the taste. She even tried mimicking Robin by pressing her mouth into her mound further to bury her face in it. She sucked a little harder, licking the nipple every time it went inside her mouth and sucked on it when she was about to let it go, and for each time she did it she found it harder to even stop to breathe in some air; and it went on and on until she just couldn't stop anymore. Lucina loved her tits.

'It's so soft…and so squishy…' thought Lucina, maddened by the allure of her sister's enormous mounds, sucking without stopping on the nipple as Cynthia squirmed.

Minutes passed and Cynthia only found it increasingly harder to keep her body under control. She kept both of her hands behind her partners' heads as if to push them hard against her bosom, while also verbally making it known just how good they made her feel. "Aahh! Yes! Harder, suck harder on them!" she exclaimed, her voice nearly cracking as her panting increased in intensity, and the two of them pressed their faces against the velvety cushions that were her breasts. Lucina curled the tip of her tongue around her sister's nipple and sucked on it, and she was lost in a frenzy of pleasure every time her nose dove on the big soft mound and it turned harder for her to breathe in her blissful suffocation.

And in turn, Cindy's legs squirmed in place as a familiar wet sensation poured from her crotch, her juices overflowing. It came as no surprise to Robin when she finally let out an even louder scream of pleasure and tensed up completely, signaling her climax. She thrashed about the bed, her grip on their heads tightening until she suddenly let go completely, giggling sweetly at them, bringing a finger to her lips in a coy manner.

"Guess you guys made me cum just from that, huh!" she said, before sitting up. "Now, why don't you two have a little fun while I recover?"

Scoffing, Robin said, "'Recover'? You've got more energy than the both of us combined. I don't think that's all it takes to wear you out."

Placing her hand on her chest, Cynthia looked at him in mock shock. "Sir, I am a delicate little flower! Okay, maybe not, but you two should have fun as well and I want to watch."

"Heh, there we go." Robin said amusedly, satisfied with her honesty. "Well then, Lucina, if you're ready?"

Once more, Lucina felt her hammering heartbeats pounding on the sides of her head, and unsure of what to do she simply folded back to the edge of the bed. It was so difficult to decide what to do! It wasn't that she wasn't enjoying her time with both of them, the wet sensation between her legs was the most adamant evidence of the waves of pleasure that stemmed from her crotch. But still, she wasn't so sure of what to do, or how to behave. Sensing her awkwardness, Robin couldn't help to turn sympathetic towards her feelings.

"Maybe you're not so ready yet…?" he said in a comprehensive tone, and though she didn't utter a word, Lucina felt profoundly thankful towards him. "Perhaps you would like to watch a little more first? There's no problem with biding your own time, lady Lucina" he added with a gentle smile.

But the elder princess hadn't still shaken the awkwardness that numbed her mind, still processing the fact she had just sucked on her own sister's breast. Though it had been wonderful, like quenching a profound thirst followed by a marvelous sensation of satisfaction emanating from her loins and warming up her entire body. But it was a mix of emotions far too volatile for her to handle and comprehend in the moment, so she couldn't find any words to reply to Robin.

Lucy, still red faced, looked at Robin with trembling eyes unsure how to respond despite feeling she was boiling on the inside. And Robin didn't know what to say either, staring deeply into Lucina's sky-blue eyes. Perhaps this was what she really wanted, to feel the excitement and pleasure of joining her body with somebody else's despite her rigorous values instilled in her. But he had also sworn to help Cynthia succumb to her urges, and the younger princess watched with dimmed eyes yet with great interest to see such a yearning romantic moment, just like in one of Queen Sumia's bizarre stories. But wasn't it a bizarre situation? Lucina got so lost in euphoria that her body moved ever so slowly to Robin's face as Robin looked on a bit before he too moved slowly to her, thinking this is what she wanted. The riling her on seemed to have worked too well on her and almost felt guilty of manipulating her conscience but it is what her sister wanted to do to help her. And after all, weren't they doing this all for her own good?

Their faces were now less than an inch apart, and Robin could almost count the tiny freckles over her nose, and their lips nearly touched…

A loud bang on the door shook the three of them and they almost fell off the bed. Lucina blinked and gasped in panic while Cynthia cursed in a low scowl. Robin turned his head toward the door wondering who it could be as much as Lucina wonders.

"Wh-Who is it?" she asked, trying her best not to sound as terrified as she was.

"Captain of the Royal Guard, Princess Lucina!" announced a masculine voice on the other side of the door.

"I'm coming!" she said as she walked to the door, and she opened only enough to stick her head out on the hall. "What is it?"

"I'm trying to find Sir Robin. Have you seen him recently?" asked the guard. "The King himself demands your presence and the Head Tactician's immediately!"

"I'm not sure where he is. I'll notify him as soon as I see him" she said in a sharp tone, showing how tired she was. But why wasn't he leaving?!

"Are you feeling alright, milady?" asked the guard, concerned. "You appear to be sweating. And you look feverish…"

"It's been a long day, I needed some rest." she replied, trying her hardest to maintain a façade of composure despite how nervous she was. "I'll meet my father at once then, if that's what he requests."

"Understood." he replied before bowing respectfully and Lucina could finally shut the door, exhaling in relief.

But when she turned around she saw Robin had already put on his trousers, and was looking for his shirt and leathery tunic. "I'm really sorry, but I should go before they get suspicious." he apologized bowing before the two princesses.

Fully stretched on the bed and displaying her voluptuous nude body, Cindy wondered something. "But what could Father want with you two anyway? I thought you had already met with him, Robin."

"I did! But I didn't get to tell the entire story, you can thank the nobles and ministers for that. You know how anxious they can get trying to tell the story first, even if they weren't there in the first place" he said, slightly annoyed. The last thing he wanted was to leave his girlfriend all naked and eager for more, but he couldn't risk getting caught or raise any suspicion. He put on his half-ripped shirt, tunic and cloak. "I suppose he wants to hear the story of what happened during the expedition from both of us directly."

"Robin please, we can't tell Father about any of this…or us…I mean, if he…" began Lucina, but Robin nodded before she could finish.

"I know. I won't say a word about our… Private affairs" he said, half teasing, half serious.

"Thank you" was all Lucina could say, sensing the sincerity in his voice. They had been so close, so close to finally ending the yearning that had taken a hold of Lucina she felt now they had taken steps back. But that didn't mean the hot tingly sensation that covered her entire body had disappeared, and seeing Cynthia fully nude on her bed was enough for her to salivate and gulp loudly.

"Aw man, what's up with all these interruptions?!" she pouted annoyed, and her massive tits jiggled as she frowned. "I can't stand it! We really ought to finish when you two get back."

"Aaah, Cynthia!" she exclaimed embarrassed. It was suspicious that Chrom wanted to meet precisely then when they were about to… Enjoy each other's company much more thoroughly. But she couldn't let it obscure her judgement, and she had to play the part of the dutiful princess once more in her father's eyes.

"I'll come back when we're finished, I promise." Robin said before putting on his leather boots and leaving for the door.

"Hmph! Well you better, mister! Make sure to bring Lucy back too!" she said evidently impatient to continue, squeezing one of her enormous breasts taunting her sister.

Robin merely chuckled while Lucina could only exhale, trying to focus when she and Robin left the room.

Now that it was nighttime, the corridors were lit by the flickering light of the candles on the walls, but they were also much emptier than in the last hours of the afternoon when they reached the castle from the expedition. Robin and Lucina climbed the grand stone staircase that led to the upper floors where the throne room was located. The princess was still evidently embarrassed of the entire situation but Robin tried to make it easier for her.

"She sure likes to tease you a lot, doesn't she?" Robin asked cautiously.

"Yes… though I think she enjoys it a little too much." She replied in a tone that shows how annoyed and embarrassed she is.

Amused by her response and expression, he dares not press it further and proceeds to walk to the King and Queen's chambers with Lucina.

---

The two youngsters reached an enormous wooden door engraved with reliefs of the Hero-King, Naga and Grima, and Lucina breathed deeply before entering the great hall.

The throne room was as wide and broad as a cathedral's hall. The stained glass on the ceiling usually illuminated the enormity of the marbled room, but now that it was night time the moonlight permeated softly inside, and the faint glow of candles gave the sensation of warmness for all who entered. The two thrones corresponding to the King and Queen sat quietly on a higher level than the rest of the room, and both Chrom and Sumia sat on them though they weren't wearing the royal robes designated for formal events, opting for richly decorated tunics favoring comfort instead of elegance. Both Robin and Lucina met at the entrance of the room and marched forth until their eyes met with the monarchs, who welcomed them with open arms.

"Ah! Robin, Lucina! We've been expecting you!" exclaimed Queen Sumia amicably.

"Please, tell us all about the incident at today's expedition." said King Chrom in a firm tone. Not pleading nor ordering, but simply wanting to know what had occurred to his daughter.

"My lord, my lady… Lady Lucina was having an expedition along with Cynthia as planned by sir Frederick" explained Robin. "As you know, we spotted a band of brigands tracking them and we followed as ordered by your majesty…"

"Oh dear…" commented Sumia out of concern.

"This is when you were knocked out, is that right Lucina?" asked the king, still using the same casual tone.

'What? How does Father know?!' thought the princess to herself, almost stepping back in shock. Her heart raced in her chest, and Robin leered at her, trying to counter whatever she said in case she messed up. "Father, I… It's very embarrassing to say, but I think I've been training too hard recently…"

"Cynthia has told me about it." added Robin. "Lucina nearly fainted two nights ago on the training grounds."

"Maybe you've been overexerting yourself, dear." expressed Sumia. "Thank you for telling us all of this, and thank you for taking care of Cynthia and Lucina, Robin. You've been wonderful in all of this situation."

"Please take good care of yourself, Lucina. It isn't like you to strain yourself to this extent." said Chrom. Now it was his turn to convey both his concern for his daughter and his relief for her being alright. "Thankfully we were able to solve this without any further harm, so the schedule for you and your sister remains the same."

"Huh? W-What do you mean?" Lucina had been so deep into fondling her sister she had nearly forgotten about Frederick's plans for them.

"Your etiquette lessons begin tomorrow." exclaimed Sumia sparkling glee. It was obvious it was her idea of fun. "Along with the rest of your studies, of course!"

"Oh… I see…"

"Is it okay if I take part in those lessons?" asked Robin, surprising both Lucina and Sumia.

"You've certainly grown closer to Cynthia, and you've been far much more useful as a tactician than any king could ask," said Chrom, smiling at his old comrade. "I don't see why not. The lessons will take place on the second floor of the castle in the room of trophies."

"I understand. Thanks for reminding me, Father" said Lucina in her usual seriousness. But inside she felt waves of relief that calmed her down. So Chrom didn't know about her private affairs or her secrets with Cynthia? Maybe Sully wasn't fully aware of everything happening around her. "I'll be going back if you don't mind then. It's been a really long day."

"Yes, of course. Robin, would you please stay for a while?" asked Chrom. "We need to find the last of those bandits you mentioned. If they're truly the last remnants of the Plegian army then we must not just discard them, I'm sure we can find their position."

"Of course, your majesty. I'll just walk Lucina to the door"

"Good night, Lucy! And good luck tomorrow!" smiled Sumia warmly.

The two of them took a couple steps away from Chrom and Sumia, whispering in voice so low the king and the queen couldn't hear them since the throne room was so spacious.

"I don't know if I'll be able to meet with you later," murmured Robin, opening the gate for her. "If I'm not back there in a couple of hours, I suppose I'll see you two tomorrow. I'll try to be there. Trust me, I don't want to leave this unfinished."

"I… understand. I will tell that to Cynthia then," said Lucina, feeling her cheeks get hotter.

Robin nodded and closed the gate leaving her outside on the corridor.

---

Lucina made it all the way back to her room where she had left Cynthia. Fortunately, it was a little late and the hallways and staircase were completely empty except for a couple of maids and stewards who let her walk unbothered. Finally, she reached the door and let herself into a heart-stopping surprise.

Cynthia was still on the huge bed, which had now turned into a mess of crumbled sheets and she was so busy pleasuring herself she almost missed how her sister entered the room. The younger princess' thick legs were spread wide open and she was caressing herself with one hand, sliding her fingers up and down at a frantic pace while her other hand was holding one of her huge breasts and pushing it upwards closer to her face, and she was loudly sucking on her own nipple letting out muffled moans that ignited the fire of lust once more inside Lucina, and the familiar tingly feeling burning up all over her body from her crotch returned, and she could do nothing but gulp at this sight.

Her small hairs stood up upon the senses of being watched, she opened one eye and found Lucina frozen, agape. She let go of her big boob with a loud smack and let it jiggle in place. "Hehe… I couldn't wait until you two came back. Sorry!" said Cynthia grinning at Lucina's intense blush. Then she blinked in confusion, "Hey, where's Robin? I thought you two were coming back together!"

"U-Uh... F-Father took Robin with him." replied Lucina trying to regain composure, but her sister's nude body was too alluring for her to even speak without stuttering. "He said he would try and come back, but I'm not sure if his meeting with Father will take up all night..."

"Oh... Darn it," she mused annoyedly, pouting and releasing her hands from her crotch and her massive tits jiggled as she frowned. An awkward silence settled between the two of them, Lucina way too timid to take the initiative to touch the younger princess' velvety thighs or mounds; but another idea suddenly burst up in Cynthia's mind.

She smirked slyly. "Soooooo… Tell me, Luce… did you like watching us?"

"Huh?!" exclaimed Lucina astonished, blushing even more.

"What did you like the most? Tell me!" insisted Cynthia crawling closer to Lucina, and the elder princess shivered as her curvaceous body approached her. "Was it my lucious boobies? I'm telling you, I've never cum before just by giving these two attention, hehe!" She shook them as they swung left and right in more alluring fashion as Lucy could not look away from them.

"C-Cynthia!"

"Or maybe it was Robin? Now that I think about it, you really looked like you wanted to put his cock in your mouth. Not that there's anything wrong with it!" she thought out loud, torturing poor Lucina who once again trembled. "But I can tell just how much you wanted it. Not just being with him, but having the whole experience… right?"

"I-I…" Lucina fumbled and stuttered her words. It wasn't until looking at her sister's coy smile did she succumb to her curiosity. She gave up and answered truthfully. Just what was the use now in denying her? She had every opportunity to leave, yet she stayed and watched. She sighed and finally admitted, facing her sister, "I… don't know what to say. Maybe I… really didn't want it to end…"

"Well, then… we have a little extra prep time now!" claimed Cynthia smacking her fist against her open palm. "How about we practice a little before Robin gets back? Let's finish our training session!"

"C… Can we?"

"Of course! I can teach you what he likes, and how to make him beg for more! It's going to be your first time after all, and I think the more you know, the best it'll be." Cynthia sounded reasonable. Lucina couldn't argue. She didn't even feel the urge to resist.

"I… suppose so. How shall we… proceed then?" She asked as Cynthia got off the bed to approach her on foot. Every step she took, her boobs bounced and Lucina couldn't stop staring. As Cynthia stopped inches from her, she placed her fingertips on Lucina's chin and lifted her face so her eyes were on hers as she smirked.

"First lesson is setting the mood right. Do you remember how we did it last time?"

Blushing over her distracted eyesight, she blushed madly again and averted her eyes downward trying to remember how it started and what they did. "I-I… think so…"

"Well then, pucker up!"

"Uh?" Her eyes turned to Cynthia's and unexpectedly, she leaned her face in towards Lucina's and laid her lips on hers. "Mmph!?" Her eyes widened as soon as the contact came. Still not used to the situation, especially knowing it was her sister kissing her, she couldn't move.

Persistent to calm her down and progress further, she pressed her body onto her, breasts and all. Wrapping her arms around her and deepening the kiss resulted in Lucina squirming slightly. Her eyes gradually dimmed and closed as she submitted to her sister's advance. Relaxed, she allowed her to explore her mouth more as she opened wider and wider. She could feel her tongue slither about, moans begin to escape her from her mouth as the familiar sensation intensified even more compared to last time. Unlike their breasts pressed against each other while clothed, their bareness caused Lucina's heart to beat harder against where her nipple pressed against hers.

Cynthia was just as aroused as her sister as she moaned in the kiss while grinding her breasts on her clothed chest. The make-out session lasted a little longer than she planned but she couldn't help herself. The taste brought sensations back from their previous session they had. Lemon pie. She didn't eat anything yet but she still tasted sweet. She still could not get enough.

Eventually, she released the kiss as both pant while saliva dripped from both their mouths as the bridge of it broke off.

"That feels… good…" muttered Lucina, when her little sister let her catch her breath for a moment.

"And you're getting good at this," replied Cynthia, smiling and sliding her hands under her sweatshirt, caressing the skin on the princess' waist. "How about you take the lead now?"

Hesitating for a moment but just like Cynthia before, Lucina went for the Pegasus Knight's lips in an almost voracious way. But her lack of experience made her bite her lower lip softly. Unstopped, she continued pressing her lips against her little sister's, licking the tip of her tongue in a delicate way Cynthia hadn't experienced before; so soft, so teasing it made her legs loosen and almost lose balance. And since Lucina was pressing her body against hers just as Cynthia had taught her, she ended up pushing the younger princess against the royal bed. As her calves hit the edge, they both fell on top of it while their make out session continued.

The quiet smacks from their lips were about the only sounds heard in the room for a while, as both sisters got entranced in caressing each other's waist and hips. Lucina was now eager to learn and was enjoying the lesson, along with finally getting the touch her body craved for so long. She especially enjoyed how her breasts squished beneath her own chest.

Cynthia was quenching her lust and enthralled by her sister's sweet scent and gentle caresses, imagining how much further she could take this. The softness of Lucy's tongue against hers was just too much! Both of their kisses turned deeper and their tongues wrestled once more, as if fighting to see who would take the lead now, and their lips covered the other's mouth almost furiously.

Lucina separated her lips from hers to come up for another breath, both panting heavily.

"I think you've passed this lesson…" said Cynthia in a soft voice, more of a moan than a statement. "Hands are next…" she said.

Her hands, smaller than Lucina's, were still underneath her shirt and went above her navel to caress her breasts. But instead of the smooth skin she had felt around her abdomen, she felt a somewhat rough texture.

"Hmm? What's this?" she asked, curious.

Lucina flinched embarrassed, backing away from her hands and bringing her own to her chest. She averted her eyes away in embarrassment, but this only intrigued Cynthia with a raised eyebrow.

"Okay, I got to see what you're wearing there. Take your top off!"

She squirmed as her face reddened more, refusing to comply.

"Lucy!" she said, imitating her surprised tone joyfully. "Come on, hands and caresses are the next lesson!"

Sighing in defeat, she closed her eyes and reached the hem under her shirt and slowly lifted it up, exposing her stomach. Cynthia was eager to see what she was hiding as more of her shirt slowly lifted. Then both eyebrows went up. Cynthia's mouth hung slightly open at the sight Lucina revealed above her stomach.

"Huh?"

Her ribcage was enveloped in white bandage straps which tightly kept her breasts pushed down and made them look smaller when she had her clothes on. She pulled her entire sweatshirt over her head and held onto it for a moment as her sister analyzed what she was wearing under her shirt the entire time.

"What are those for?"

"I… wear these every day, Cindy…"

Perplexed, she continued to stare until looking at her sister's dismayed expression.

"You think you are the only one who hates wearing dresses?" replied the elder princess, a bit exasperated at her pondering. "You know my role in the battlefield is to close in on the frontlines, marching against the enemy. And these two…" she said, stressing the last two words. "…sometimes get in the way. It's been like that since… you know, since before we came to this time. And well… I made a habit to wear these every day, even now that the war is over…"

Looking at Lucina's breast, she thought it was no wonder they got in the way of her moves. Despite being pushed down by the bandages, her boobs were even bigger than Cynthia had previously thought. And her mouth watered upon this realization.

"Wow, I never knew…"

Reminiscing their dark times momentarily, she admired how she took liberty on it to fight effectively. Yet why she kept them on after all this time after the war ended, she couldn't wrap her head around it.

"Welp then, take em' off! I've gotta' see what we're working with," she said impatiently.

"I don't know. I feel I may have gotten used to having them on."

"Ugh! Oh Luce. How are you supposed to know how this feels if you're keeping the straps on your chest?" she replied, rolling her eyes. "Or perhaps you'd prefer to touch mine again?" she added, smiling devilishly as she caressed and squeezed her boobs.

She stared before darting away with uncertainty. "Mmmh…"

"It's up to you, sis."

Lucina turned her trembling eyes back to hers.

"What do you feel like doing?" Cynthia asked enthusiastically. As eager as she is to proceed where they stopped, she patiently waited for her to decide which tactic she's comfortable proceeding with first. She adjusted herself over the soft mattress and placed her head on an enormous red velvet pillow, spreading her arms out waiting for her actions on her. Lucina blinked and her eyes fell on her breasts again. She reluctantly got over her and placed her right knee between her legs. Cynthia coyly smiled and saw her hesitating hands rise from where they were hanging and slowly approached her globes… then her arms stopped moving.

"Oh come on, here!" she said peevishly, and brought her unsteady hands to her own huge bust and placed them there. Exhaling from the reminiscent touch, the soft surface made her feel the extra pleasure and sensation of her sister's hands and elicited a soft moan from her. Still smiling, she released her hands on Lucina's, signaling for her she could massage them and do as she pleased. Mesmerized, she continued to squeeze them, knead them in circles and press them together. Cynthia moaned at the diligent care her sister was taking to pleasure her chest.

She then took her hands to Lucina's back to untie the white bandage straps. Realizing what she was up to, Lucina released her grip on her sister to grab her hands. Cynthia looked confused while Lucina's eyes darted away with uncertainty.

"I-I'll do it…"

Reluctantly, she releases her sister's hands as she herself goes for the knots and undoes it. The younger princess took a moment to delight her eyes on what she was seeing. Her older sister, one of the most gorgeous women she had ever laid eyes on, was on her knees but still on top of her, getting undressed solely because of her, longing to see her sister remove the bandages.

"They're not as big as yours…" she finally said after removing the bandages. Her boobies were as she said, not as large as Cynthia's, but began to bulge out of the last layers of straps confining its freedom. Finally, after the last few layers were removed, her mounds bursted out as the rest of the straps fell off, onto the bed and some on the floor. Her bust was a respectable spherical size and surprisingly perky despite being quite full and fleshy. Her light pink nipples had small areolas around them, and stiffened upon her sister's gaze, filled with desire. "Please don't stare at me like that…" It was the first time she got naked for somebody else to see, and even if it was her sister, it felt embarrassing for her to have what she thought were small and unsatisfying breasts.

Cynthia was amazed at the size and shape, she reached out and began caressing them. "You've got nothing to be ashamed of… they're much bigger than I ever thought! And much softer too…"

The elder princess swallowed and panted softly, as she felt her entire body getting hotter and hotter by her touch. She looked at her sister's hands on her chest and observed her playing with them for a while before proceeding herself to massage the Pegasus' Knight's own breasts, squeezing them harder. Both of them barely fit her palm, and small blobs of flesh poured from the gap between her fingers.

"Mm…" she sighed. "…I'm thinking you might be ready for a new trick Lu…" She took her hand underneath the pillow and took out a somewhat long and thick staff of about twenty inches. Magical staves got their usual length upon activation, but usually they measured around twenty inches for transportation purposes, and this one was crowned with a small pale jewel.

"I read about this trick in Mother's book, but well… you're supposed to do it with a guy and since there's not one around, we'll have to improvise a little."

"What do you mean?" asked Lucina, quite curious.

"Well you see…" she said as she sat up straight. "You know guys have their shaft between their legs right?"

"C-Cynthia!" exclaimed Lucina for the umpteenth time.

"But you've even seen Robin's!" she exclaimed laughing. "Anyways, you're supposed to place it between your boobies, just like this…" she pressed her juicy breasts together, holding the staff in place as it was supposed to be performed on a male. All of it under Lucina's attentive stare. "…and we move them!"

The older sister grabbed the other's mounds and made them move up and down, precisely as Cynthia had instructed her. It was so similar to the way she had massaged her before, Lucina thought. But she imagined it would be easy for her sister to do since she had such a huge bosom.

"Do you really think I can pull this off?" she asked, unsure.

"You travelled from the future to save the world from Grima… and you're not sure you can do this?" laughed her sister, drawing a comforting smile. "It's no big deal, I'm sure any man would go crazy on you. I mean look at you! Look at them!" she said, gently pinching her left nipple, making her moan. "You got more than enough to do this, Lu. Embrace what you got and try to feel comfortable in your own skin. I remember Robin told me that once…"

A moment of silence followed, but none of the sisters removed their hands from each other's body. "I can see why you like him so much…" uttered Lucina, offering a gentle smile. "So I'm supposed to please him with my breasts like that then?"

"Sure! It's your turn to practice now!" replied Cynthia, placing the staff between her mounds and carefully pressing her sister's perky and soft breasts around it, so it would be kept in position. Lucina began shaking her torso, bouncing her boobs, but it wasn't exactly how it was supposed to be done. "Use your hands to push them together. The tip is supposed to come out on top of them…"

"Ah…? Ooh…"

Following her instructions, she pressed them effectively trapping the staff, while Cynthia held it from the bottom so it wouldn't fall. Slowly, Lucina made her breasts slide across the length of the staff, and its smooth wooden texture caressed her skin in a way they hadn't experienced before, turning them a slight shade of red. Before long she was shaking them in the correct manner, up and down, time and again, and her little sister couldn't help to rub her hands on one of the other princess' mounds, gently stroking the nipple and sucking her own lips in the process.

"That's more like it, yes…" sighed the younger sister, staring at the beautiful spectacle the other was offering. Then an idea flared up in her head. "We can even do it together! Hold it there!" Without hesitation or waiting for any response from her sister, she pressed her big breasts against Lucina's smaller but equally seductive ones, trapping the staff between their mounds.

The soft pressure and sensation made the older princess let out a sigh of pleasure, for it wasn't a feeling she had ever felt before. Then, Lucina began sliding her large boobs down the shaft, so she couldn't stop moving if she still wanted to feel the delightful touch of Cynthia's softness. They both moved their chest up and down rhythmically, at the exact same pace, and gazed at the other's facial, lustful expressions; so beautiful it made Lucina dampen her undergarments and Cynthia dripping from her sex.

"Now you got it, Sis…" moaned Cynthia, closing in on her to deliver one final and passionate kiss. Their tongues fondled as Lucina grabbed and played with her sister's nipples for a little while before their lips separated. "…Training session, finished."

A thin strand of saliva connected both of their mouths, which Lucina licked as Cynthia had done in the beginning of their session. But as soon as she had done that, she seemed to turn a bit sour, and her excitement seemed to diminish.

"Are you sure this is a good idea Cynthia?" she asked, doubtfully.

"What do you mean?"

"I think… There's something wrong. What would Father say if he, or anyone in the court finds out about this?" she bit her lips slightly anxious, heart racing. "I don't think it's good to keep secrets from them, or Mother…"

Silent for a moment, Cynthia wrapped her arm around her sister's shoulder and led her to lay on the bed sideways with her. Both heads landed on Cynthia's large luxurious pillow as they both stared at each other. Cynthia's hand began to caress her sister's shoulder, rubbing it back and forth to calm her anxiety and worry.

"Well Lu, when Robin and I first started, we knew it wasn't something we could really tell Father right away. It's not wrong, but not many people may be able to understand it…" she began stroking her sister's hair, twirling one long blue lock. "That doesn't mean we wish to hurt them on purpose, but there are some secrets we can't confide to our parents," she continued. "They might be judgmental or overprotective, you know? Instead we turn to our friends and ask for their counsel. Sometimes they can be wiser and relate more to us than our parents… it's just something people in love do. I'm sure Mother will understand."

Lucina blinked heavily as she absorbed every wise word Cynthia could deliver and thought how it is acceptable to be discreet about such actions that can run risks over discovery and worry what her father would feel about it. How can it be so easy to live carefree without concern? How will she be able to handle it herself and do what they do? Just what is she supposed to do?

Her eyes darted down at her sister's bulbous breasts. Her eyes tremble as she stares at them for a while, liking how squished they are together. Tempted to reach for another touch, she became too tired, too aroused and too overwhelmed to decide what to do anymore. She blinked a bit as she felt the weight of sleep blanket her.

"Lu," her sister continued on. "I want you to feel good about letting go. And for the first time in a long time, I saw you begin to do that with me and Robin…"

Lucina's eyes dimmed more as Cynthia stroked her hair, twirling locks here and there just like how mother did to help her sleep. She seemed to pick that skill up well as the effects were working on her. It felt like a fever dream and maybe tomorrow she'd be back to her normal self. But right now, she couldn't hold onto her sister's words any longer without them blurring together.

The last sight she saw before closing her eyes were her sister's two nipples staring back at her. Even if this might never happen again, she knew she'd be seeing them in her dreams, at least one more time tonight.

Cynthia then looked down. Her sister was sound asleep.

Battle after battle, self imposed repression after repression to keep her composure among the troops, to keep face among the nobility, Lucina finally found some brief respite nestled up to her younger sister. And for that, Cynthia felt like she had finally done something meaningful for her proud older sister. Smiling softly, she stroked her hair once more, whispering, "even if for just a while longer."

Relief indeed! Overwrought or not, I feel relief that I finally got this chapter taken care of. I delayed it lots of times and not only is it longer than the last chapter, harder too because this chapter was originally intended as chapter 2, at least half of it. When I hired the original writer Odoacro, I wanted to include Lucina into the mix due to her witnessing and feeling aroused at the sight of their sex activity. She still can't stop thinking about it and it is destroying her inside so this is about relieving her… or tried to. See, originally, Robin was going to have sex with Lucina but I decided to reserve that for future chapters. Instead, they were interrupted by the guard that ties into the next chapter. So putting all this together did take a long time to figure out how.

I also needed help proofreading it and writing how to end it because it was left as Lucina lying in bed with Cynthia while she consoles her. She wakes up in the next chapter but I wanted her to fall asleep. I just couldn't figure out how and it seemed too simple but I wanted to add last things to make it deep for Lucina's situation to reflect before dozing off.

I had to ask advice on things regarding Lucina's behavior because of how conservative she is. Someone told me it's important we take into account that characters with very specifically predefined morals and ethics often experience denial when confronted with thoughts and feelings that aren't consistent with how they believe they should ideally behave or feel.

There's a story called The Art of Seduction where it explains how Lucina is a lonely leader and how powerful people are not necessarily different from everyone else. These types make superb victims because they are relatively docile if you give them what they want. So to seduce such tpes, it is better to act like their equal or even their superior, the kind of treatment they never get. It was difficult for Cynthia to seduce her due to her being too intimidated to try, or use the kind of tactics like flattery and charm. Robin being those things and Cynthia seducing her became challenging and when she became blunt with her, it became a bit dangerous for the lonely leader because they can be made emotional by inflicting some pain, followed by tenderness. That's why it she is one of the hardest types to seduce, not only cuz' she is suspicious of Cynthia's antics but because her mind is burdened with cares and responsibilities. They have less mental space for seduction so Cynthia was patient with her and clever with filling her minds with thoughts of her. And I felt that may be too much cuz' I felt like Cynthia, being the immature type, would be treating Lucina like a child as she consoles her. But that became further from the truth. Because Cynthia is the alpha female in her relationship with Robin, it is acceptable to allow Lucina to not fill the typical alpha female position she otherwise would outside the bedroom. Inside the bedroom, the younger sister holds the power. Outside, Lucina holds it. For in her loneliness, she may come to depend on Cynthia for support.

That's definitely pretty deep stuff to think about. Lucina didn't struck me as a kind of lonely leader because she had all her friends, but she always yearned to be with her family. But I remember after you beat the game, if you don't pair Lucina up with anyone, she wonders off alone. It makes me concern for her to be alone and so I thought maybe this is accurate than I thought. At first, Lucina was doing fine before witnessing Cynthia's sex escapade which suddenly changed her life but I wasn't sure if for good or bad. I was bothered over some things I saw on the internet regarding sex and it took me years to accept it. But I didn't have that loneliness before, I was just disturbed by it. So that's how I made Lucina to be in this story; bothered, aroused, disturbed and distracted by her daily life. But maybe it opens up more things in her as she stalks the two and yearns something from them. It is definitely relief but not the way it should be. This is still a lemon story so lots of erotic and crazy things can happen, incest being one of them on top of two girls kissing and touching. But still, it does fill some void in Lucina's yearning like a child would so it's not too unusual for her to be like that, especially considering how attached she is to her parents. I read in another fanfiction that she keeps 2 plushies with her that brings secure in her small space, even if it seems childish. She's a girl, despite being mature most of the time. Everyone has secrets so its normal to not show your personal side to other people. Only with people you trust.

Anyway as I said, this chapter was originally written by Odoacro when Robin and Cynthia get raunchy in front of Lucina, but the rest was written by Vic1992 so once again, shout out to him over on Fiver. He's been backtracking a lot because of me but he was very patient and invested in helping me make this good. The last person to proofread and help write the last 3 or 4 paragraphs to end the chapter was a huge help. He goes by quitobarajas both on fiver and upwork. I've been trying to find help and not one was quick to respond to my proposal. I hired some people but they did a poorly job so I had to seek refunds. But all that matters is this chapter is finished and I apologize for the long wait. I'm working on the next chapter and I hope the upload will be a bit quicker.
Other than that, y'all let me know what you think of this one. Thank you so much for your patience, thank you for reading, and stay tuned for more of this lemon story.
