AN: Sorry for the huge delay on this one, guys! I got a bit stuck figuring this one out (and debating if it was the right thing to do), and then I had some unexpectedly busy weekends. I just hope I didn't create too many high expectations and that this finale satisfies!

Prompt: Morning Sex/Outdoor Sex

Chapter 7: Competing with the Neighbors

One of the pleasant surprises Sesshoumaru learned about Rin during their cohabitation was that she enjoyed morning walks. Once the families had settled into a routine, she started delaying her showers in the morning to take walks first, and Sesshoumaru would join her, his feet always having been restless. Besides, these walks were rare moments he could spend alone with his wife.

They took turns leading, often changing up where they went—sometimes it was along the road, other times it was along the river, and often it was just blazing a trail in the wild Zone and letting Sesshoumaru find their way home afterwards. That morning, as they were passing by the obstacle course, Rin commented, "Setsuna was so happy yesterday when you went to watch the girls compete on the course. I think that might have given her the extra boost to win."

"She has been training well. It was inevitable she would catch up to Towa and Moroha eventually," he answered.

Rin stopped and ran a hand over the netted rope leading up to the wooden platform that began the obstacle course. "They always look like they're having such fun when they play—er, train here. I'm glad." A sad smile crossed her lips. "I never got to experience anything like a camp when I was a kid. It's good they live in a world where that's possible."

Sesshoumaru waited for her to resume their walk, but Rin continued to stare at the course, a longing in her eyes. So he said, "You should try it, Rin."

"Do you think I can?" she asked, her eyes shining with hope. "I've felt so much more energized since we came back from the Tree of Ages. I really think she took some extra years off me or something, because I haven't felt so alive in I don't know how long. Oh, I do want to try!"

She immediately clambered up the ropes and ran across the bouncing wooden bridge without a care for the water of the river rolling below. Sesshoumaru leapt across the stream to the tree on the opposite side, which Rin raced around until she came to the peg-stairs hammered into the trunk. He was about to offer his help when she bent down and grabbed a peg with her hands before stepping onto the one below it. She wobbled as she got her balance, and Sesshoumaru stayed beneath her, ready to catch her in case she fell. Slowly though, she found a rhythm in moving her hands and feet one at a time to climb the pegs.

She would certainly win no races, but he was proud of her for finding a way up on her own. He also enjoyed watching the way her athletic leggings showed off every delicious curve of her ass as she kept it hoisted high in the air. What he wouldn't give to fly up there and take her then and there….

Breed her, his demon urged, and he batted it away. There was no reason he should be feeling so horny this morning.

When she finally reached the next platform, she smiled with a sense of victory, only for it to vanish when she saw the rope swaying suspended between her and the next platform.

"I might have…overestimated my abilities here," Rin said.

He readied himself to fly up and bring her back down when she held out her hand to stop him. "Wait, just stay there. You'll…catch me if I fall, won't you?"

"Always," he answered.

She nodded. "Right. Then let's do this." She took as much of a running leap as the short platform would allow and stretched her arms out as far as she could to reach the rope. However, the course was designed for half-demons who could jump longer distances with ease. She started her descent well short of the rope but still tried to grab it. She managed to catch it towards the end, but the sudden jerk of gravity against her body as she stopped herself caused her to lose her grip.

Rin screamed as she fell the rest of the way, and Sesshoumaru leapt up, catching her with nary a jostle. She clung onto him like a burr as he landed.

"Are you hurt?" he asked her.

"I'm okay," she answered breathlessly. "Just…give me a sec." Her chuckle was weak when she next spoke. "I guess I learned my limitations there, huh?"

"It takes practice, Rin."

"I suppose you're right…."

The disappointment in her voice pricked at his heart, so Sesshoumaru held onto her as her body relaxed from the traumatic experience. Seeking to calm her, he nuzzled her scalp, sniffing her instinctively to make sure nothing else was wrong. There was that spicy scent to her blood—the one prey got when being chased by hunters (what did Setsuna call it—adrenaline?)—but beneath it, there was something else about her scent that seemed somewhat familiar, and yet he was having a difficult time recalling why. It was a robust fragrance that called to him, as an aged red wine might to a connoisseur.

He froze as the memory—and bone-deep knowledge—hit him.

Fertility.

His arms tightened around Rin as his body went hot. Now his sudden bout of lust made sense. His mate was oozing pheromones that his demon was denying to respond to. Her thin, skin-tight clothes were hardly a barrier. If he just inched his hand down, he could have her ready for him in seconds and then take her on the grass—

No, he needed to control this.

She was scared and hurt, and they may have agreed to be open to children, but it was still early in their reunion and—

"Mother, are you okay?"

Sesshoumaru, for once thankful for the interruption from his daughters, turned around with Rin to find Setsuna and Towa on the opposite bank of the stream still wearing their sleepwear. Even Moroha and Inuyasha came bounding after them.

"I'm fine, Setsuna. I just bit off more than I could chew. Sorry to disturb everyone!" Rin warbled as Sesshoumaru flew her back to the other side and set her down. When she lowered her arm from his shoulders, she winced.

"Mama, are you hurt?" Towa asked.

"I might have wrenched my arm a bit…and gotten some rope burn," she added, flexing her hands open and closed. Raw, red streaks bisected her palms.

"Then we should put some salve on them!" Towa exclaimed. "I'll run back and get some—"

"You don't even know where the medicines are," Setsuna answered.

"Did someone call for a first aid kit?" Kagome shouted, running up the way and waving the aforementioned object in her hand. Along with Inuyasha, she was the only other one dressed and ready for the day, wearing a skirt in celebration of the warming weather, although the morning air still contained a distinct chill.

"Guys, it's really not that big a deal," Rin protested.

"Nonsense. The way Inuyasha and Moroha flew off after that scream, I feared something major had happened and brought this along just in case," Kagome said, opening it up and digging through the supplies. When she pulled out some ointment and gauze, Towa and Moroha immediately grabbed the items and pulled Rin's hands to them, applying the salve and expertly wrapping her palms.

"Oh wow, you guys really know what you're doing!" Kagome remarked.

Towa laughed. "Yeah, well…let's just say we've had to bandage ourselves up quite a bit over the years."

"So what exactly happened here?" Kagome asked Rin.

Rin glanced sheepishly at the obstacle course. "The course looked like fun, so I just wanted to give it a try. I fell off the rope swing."

"Good thing Papa was there to catch you!" Towa said with a smile.

"What the heck were you even doing up there in the first place, Rin?" Inuyasha griped. "This course is made for half-demons. Of course it's too dangerous for a human to complete."

"Inuyasha, don't say that! We may not be as strong as you guys, but we can be creative!" Kagome retorted. "I have a mind to go try it myself now."

"No you don't!" Inuyasha bit back. "Just because you're immortal now, that doesn't make you invulnerable!"

"But it looks like so much fun whenever the girls do it," Kagome whined. She sighed dramatically. "I suppose that's the price I pay for being human."

Moroha's eyes suddenly lit up as she screwed the cap back on the ointment. "I know! What if Dad and Uncle Sessh carry you guys along the course? That way, you get to experience it without putting yourselves in danger."

Kagome clapped her hands together. "Oh Moroha, that's a wonderful idea!"

Inuyasha slammed a fist into the cup of his hand. "Heh. Make it a race, and I'm game."

Sesshoumaru huffed. "How childish. This course poses no challenge to me."

"Oh yeah? I bet you're just afraid of letting your kids see me whoop your ass," Inuyasha replied.

Sesshoumaru narrowed his eyes at his brother. "I have nothing to prove. I could run this course blindfolded and still beat you."

"Oh yeah? Then do it."

The glade was silent as everyone stared at Sesshoumaru, waiting for his answer. While he rarely turned down the chance to put Inuyasha in his place, Sesshoumaru preferred to do so only if he was going to get something out of it. At least when they had crossed swords, he fought with the intent of taking the Tessaiga. Even now, a duel with Inuyasha could help him keep his skills sharp in what was looking to be a very peaceful life ahead. But as a full-fledged demon, he saw no need to waste his time on such a course. After all, he could fly, so what was the point of it?

But then he made the mistake of looking at Rin. It was the combination of expectations in her eyes—that she could have fun and that he could, in fact, run the course blindfolded—that gave him pause.

He could not let her down.

"Very well…since it appears you need the handicap," he answered.

"I do not! I've run this course so many times during camp, I could also do it blindfolded!" his brother spat.

"Whoo, sounds like we have ourselves a proper challenge!" Moroha cried out with a fist-pump.

"I will secure proper blindfolds," Setsuna answered with a small smile, running back towards the cabins. Even Towa looked excited. Were all the girls truly going to find joy in this meaningless show?

Well, perhaps it wouldn't be such a waste of time then.

When Setsuna returned, she and Moroha tied the blindfolds around their fathers' eyes, making sure they couldn't see anything. With his sight gone, Sesshoumaru's awareness of the others' demonic auras increased—as did those of his other senses. The soft tickle of Setsuna's fingers arranging the blindfold, the rustle of crushed grass as Kagome pulled Rin away with a hushed word, and the fresh scent of new spring growth in contrast to the sharp but dead scent of the pine planks and pegs on the obstacle course.

And Rin. Fertile, fertile Rin, who was going to have her body wrapped around him.

Damn it. This may have been a mistake.

A small gasp made him swivel his head in Rin's direction. He had been so engrossed in his own thoughts, he hadn't heard their conversation until now. (Inuyasha, meanwhile, was engrossed with Moroha in a debate about how tight his blindfold was.)

"No! Kagome, that's so mean!" Rin hissed in a hushed voice.

"Nonsense. We're their wives! Besides, those two muscle heads are always up for a challenge. Heck, we're just along for the ride at this point. Call it our own challenge."

"So, what you're saying is…instead of rooting for our own husbands to win…we're trying to sabotage them?"

"Yep! And whoever's husband succumbs first is the winner!"

Rin giggled. "So really, there's no loser to this game no matter what. Is that what you're saying?"

"My point exactly."

"But you're in a skirt. That seems a little unfair."

"Your husband is a full-blooded demon. I'd say we're just evening things out."

"True. Alright, I can get behind this game."

"Great! Oh, shit, Sesshoumaru's looking at us. Do you think he heard?"

"Mmm. Only one way to find out," Rin answered with a curious lilt to her voice.

What exactly were those two planning?

The girls led everyone over to the start of the course, and the women ambled back to them. The closer Rin got, the stiffer his body became.

This was one handicap he hadn't needed.

"Best of luck, Big Brother!" Kagome said, patting his shoulder and causing him to flinch. But her proximity and the brief touch allowed him a bigger whiff of her scent, and Sesshoumaru realized something.

Kagome was fertile too. Meaning he would not be the only one suffering from holding back his instincts—assuming Inuyasha had those. (He had never exactly cared to find out.)

"Hey, Kagome!" Inuyasha snapped. "What are you cheering on the enemy for?"

"First off, he's hardly your enemy. Secondly, it's called sportsmanship. Ever heard of it?" she grumbled as she jumped onto Inuyasha's back.

The way he grunted when she clambered on might have sounded normal to most, but with Sesshoumaru's heightened senses and new knowledge of his sister-in-law's state, he detected a hint of desperation in that grunt.

Good. They were fighting on even terms.

"Are you ready?" Rin asked, coming up behind him. In response, he coiled his fur around her, causing her to yelp in surprise as he deposited her on his back. When she hooked her legs around his hips and pressed her core flush against him, he had to bite back a growl.

He could just imagine her naked, grinding that wet pussy across his spine….

His fur crept under her butt, keeping her secure against him but, more importantly, keeping him in contact with the part of her he most wanted to feel up right now.

"Okay, here are the rules," Setsuna announced. "You must touch every obstacle of the course as intended at least once. This means no flying or leaping over chasms. Doing so will result in disqualification. However, as this is a race, you are free to leap past your opponent, keeping in mind that you must at least touch the obstacle you're on. First one to zipline down to the bottom wins. Any questions?"

Silence.

"Then when I whistle, the race begins. Three…two…one…fweet!"

Sesshoumaru grabbed hold of the netted rope in front of him and started to climb. Rin adjusted herself along his back, her breasts pressing against his shoulder blades, her sex dragging along his spine, and her knees sliding against his ribs.

Was the woman trying to drive him mad?

His distraction must have cost him a spare second, because Inuyasha beat him to the platform and took off running across the bouncing suspension bridge. The boards rattled in Sesshoumaru's ears, taunting him as he stepped onto it.

Judging from the sound of Inuyasha's bare feet hitting the boards, he wasn't too far ahead. When the boards caved once more beneath his feet, Sesshoumaru bent to jump, and using the momentum from when the bridge crested, he leapt into the air.

And he judged his landing perfectly.

He used Inuyasha's head as a stepping stone to vault to the opposite platform.

Kagome screamed, and Inuyasha yelped. "OW! Damn it, Sesshoumaru—you're going to pay for that!"

Sesshoumaru paid him no heed, hurrying around the tree and feeling for where the pegs started. But as soon as he put his foot on the bottommost one, Rin shifted again, her breath hot against his ear.

"So naughty. You shouldn't jump on your brother's head like that, Sesshoumaru. How should I punish you?" she asked.

"What?" he asked.

Then her hand snaked into his kimono, her fingers dancing down his pec until she reached his nipple and pinched it.

He sucked in a breath, his claws gouging the bark off the tree.

"Whatcha standin' around like a statue for, Sesshoumaru?" Inuyasha taunted, leaping up behind him and grabbing a tree branch before vaulting onto the pegs and running up.

Sesshoumaru brushed Rin's hand from his chest. "Rin, do not distract me."

She just laughed evilly in his ear—then swiped her tongue along its edge and bit it.

He hissed. What was going on with her? This wasn't the Rin he knew.

It became more apparent when he reached the next platform, and Inuyasha hissed, "Oh, shit, Kagome."

"You like that?" Kagome murmured in his ear, and the rustle of fabric told him she was stroking somewhere.

Rin giggled, the flutter of her chest against his back sending a wave of tingles up his vertebrae and shooting straight for the base of his skull. "Oh, you're starting off downright dirty, Kagome. Nice work!"

"What the? What are you minxes doing here, exactly?" Inuyasha snapped.

"What's it feel like we're doing?" Kagome asked, and the way his brother sucked in a breath made Sesshoumaru imagine he was being squeezed somewhere.

"Oh, don't look so jealous, Sesshoumaru," Rin purred in his ear, brushing her fingers against his cheek and down his neck. "I've got plenty of love for you too." Her heel moved down, running along his crotch, and Sesshoumaru froze, unable to move.

"Hey, what's the holdup?" Moroha shouted from across the stream. "I thought you two said you could do this blindfolded! Is jumping through the air without looking that scary?" The girls all broke out into snickers.

Sesshoumaru did not appreciate being laughed at. He turned and tried to recall how far the rope was from the platform here.

"Out of the way," Inuyasha griped, pushing past Sesshoumaru and leaping off the platform.

Damn. He had gotten ahead of him again. Was his brother relying on muscle memory? Even Sesshoumaru needed to pause here to assess before leaping into the abyss.

"You can do it, Sesshoumaru," Rin said, all trace of the vixen gone. "The rope's about six meters away. I'll tell you when it's about to swing toward us. Ready?" Sesshoumaru crouched. "And…go!"

Sesshoumaru leapt, stretching out his arm. Given how Rin didn't scream, he must have been on course, and then he felt the cord bat his body and grabbed it. After one swing, he let go, soaring as far as he felt he had jumped before, landing so close to the tree, his nose must have been nearly pressed against it from how strongly it smelled.

Rin guided him through the next two ropes as well, not making another sexual move against him, perhaps remembering her fall from earlier and not wanting a repeat. After clearing that obstacle, he came upon the rope he was meant to climb down to a lower platform.

The rope jostled in his hand as he grasped it, squeaking as Inuyasha shimmied beneath him. He had the strongest urge to let himself drop right on top of his brother and use Inuyasha as a cushion for the fall. But Kagome was on his back, so he couldn't put her safety at risk.

But while he was deliberating, Rin renewed her attack.

"Sesshoumaru," she murmured against his neck, brushing his thick hair away and kissing his nape. She sucked his skin between her teeth, intent on leaving a mark upon his skin.

His neck prickled with the awareness of her mouth against it, but Sesshoumaru fought against the distraction, grabbing hold of the rope with a single hand, stepping off the platform…and then letting them fall.

Rin screamed in his ear as they plummeted, and even Kagome shrieked, "Move, move, move!"

He tightened his grip right before he sensed he would land on Inuyasha, and Rin tensed against him.

They jerked to a stop.

Then Sesshoumaru lowered his foot onto Inuyasha's upturned face and used it once more as a stepping stone before leaping to the platform below.

"Damn it, will you stop doing that?!" Inuyasha bellowed. "I ain't Jaken!"

He knew what came next: the rope bridge. Two ropes crossed in an X over a third, and the crossed ropes were meant to act as a handhold. But Sesshoumaru would not have any need for that. As a demon, he was naturally balanced.

After feeling for the position of the top rope, he jumped up, landing neatly upon the inclined rope, and then started walking forward.

He was prepared this time when Rin shifted upwards and nipped the tip of his ear, though it still sent a shudder coursing through him.

"What, not even this? But it's your most sensitive spot," Rin whined, giving him a lick behind the shell of his ear. His back broke out in gooseflesh. "And here we're almost through. Guess I'm going to have to pull out the big guns now."

Sesshoumaru steeled himself. He still didn't understand why Rin was doing this, but he had a race to win, and—

Suddenly, Rin shifted, pulling away from his back while still hanging onto him with one hand. His fur was all that kept her from falling off. She reached between them, low against his back, her hand moving back and forth. He frowned, confused. Was this supposed to arouse him?

"Oh gosh, I'm so wet today," Rin groaned, and he froze on the rope. No, she can't be. But the growing smell coming from her only confirmed it.

She was fingering herself. Here. In the open. Against his back.

"I only get this wet when I'm…." She leaned forward and whispered in his ear, "Ovulating."

A growl rumbled in Sesshoumaru's chest, and he clenched his hands together.

"Here, darling. Have a taste."

And before he knew it, she pulled her fingers out of her pants and brought them around to his face, smearing his lips and the bottom of his nose with her juice.

At that same moment, the rope jerked beneath his feet.

Inuyasha would later claim that it was because he jumped onto the rope bridge that Sesshoumaru fell off. But Sesshoumaru knew the real truth. The sudden scent and taste of a fertile Rin smacked him so hard in his olfactory glands, he fell off the rope like a stunned bird.

Rin's yelp was enough to jerk him back into awareness not half a second later, and he grabbed the rope with a single hand, halting their descent.

"Bwahaha!" Inuyasha laughed, coming to stand over Sesshoumaru and crow. His brother never could resist gloating. "I can't believe you fell off so easily!"

"Girl, I saw what you did there," Kagome said in a salacious tone.

"What'd she do?" Inuyasha asked.

"That was downright nasty," Kagome continued with unrestrained glee.

"So do I win?" Rin chuckled.

Ah, now their earlier conversation made sense. But they were certainly playing with fire.

"This race isn't over yet," Kagome answered. In a lower voice meant for Inuyasha's ears only, she said, "Inuyasha, I don't feel so secure. I think you need to readjust your grip…."

"You don't need to grab me. I can—oh, holy shit, Kagome," Inuyasha gasped as if he'd been sucker-punched.

"You feel that, big boy?" Kagome murmured in his ear—meaning it might as well have been in Sesshoumaru's ear as well. "All that wetness is for you."

Rin, who must have been watching, gasped one second in shock and huffed in frustration the next. "I knew that skirt would make it easy," she mumbled.

Sesshoumaru should have known his Rin would rise to the challenge.

She slid a few centimeters down his torso, causing his entire body to lock up at the sensation, and as soon as she was low enough, she dipped her hand into the front of his hakama and grabbed his dick. Sesshoumaru jerked as she started to rub it, his already tightened groin growing downright tense.

"Rin—" he tried to warn.

"Just getting you ready, Sesshoumaru. I'm all sorts of turned on now, and I'm going to need some relief when this is over, you hear?" Rin said.

Sesshoumaru growled, his teeth and claws elongating. Relief? She wouldn't get relief.

She'd get bred. Hard.

Her hand was doing a fine job of priming him, but now he was torn. Finish the race or leave and breed his fertile mate?

"Damn," Kagome said. "Inuyasha, I think Sesshoumaru is getting more turned on by his wife than you are by me. Just look at that tent," she whined.

"Say what?" Inuyasha asked in a wary yet accusatory tone.

"You heard me," Kagome said with a grunt, shifting on Inuyasha's back and causing him to growl. "I bet he's ready to drop out of this race and have his way with her. Isn't that right, Sesshoumaru?"

His silence was all the answer she needed.

Kagome sighed. "But I guess I'm worth less than a win against your brother, hmm?"

"Dammit, Kagome—now you're asking for it!"

Suddenly, the rope popped up and branches rustled as Inuyasha bounded away.

"Aw dang, she won," Rin sighed against his back, removing her hand from his pants without so much as a "by your leave."

Rin thought she had lost?

She was sorely mistaken.

Sesshoumaru swung them back up onto the rope and ran the rest of its length. When he reached the zipline on the other end of the platform, he grabbed it and slid to the bottom. Once he landed, he loosened his fur, and Rin slipped off his back. When Sesshoumaru didn't move to take off the blindfold, Rin reached for it, saying, "Here, love, let me get that for you—"

He batted away her hand.

Rin sucked in a breath. "Sesshoumaru? Are you…angry perhaps?"
There was only one part of him that was angry, and that was his cock.

But he said nothing, because he was using every ounce of his self-control to hold himself back from pouncing on her in that moment. But he couldn't. Not yet. Because—

"Yay, congrats, Papa!" Towa exclaimed, bounding over. Sesshoumaru kept his back towards the approaching children, as he was still not in a state to be seen from the front. That didn't stop Towa from hugging him from behind. He didn't dare move. She wouldn't think it strange.

"What happened? Where are my parents?" Moroha asked. "You guys were neck-in-neck the whole time."

"Umm, well you see—" Rin hedged.

"Go to the arena and begin your morning lesson," Sesshoumaru bit out. Would the girls hear his slight lisp as his lips tried to cover his enlarged fangs? "All of you."

"Umm, okay," Moroha answered.

"Are you alright, Father?" Setsuna asked.

"I am fine. Go."

"Guess playtime's over," Towa sighed. Come on, let's go."

Once the children were out of earshot, Rin turned back to her husband. "Sesshoumaru, what's wrong? Why haven't you taken off that blindfold yet?"

"Rin—run."

"W-What? Why?"

"I will give you three minutes to navigate the forest. Run."

"O-Okay…." Then she turned and fled into the trees.

Sesshoumaru took a deep breath, inhaling the scent of her arousal still upon his upper lip. And then he began counting. The thrill of the hunt trilled in his blood, and keeping his eyes covered would only prolong the game against his human mate. He planned to enjoy every second of it.

As soon as he hit the three-minute mark, he shot into the forest. Her musky scent led him on a tantalizing chase, and he dodged trees with relative ease even though he could not see them. His entire awareness was focused only on his nose. He breathed in Rin's scent, his blood running hotter as the demon within him urged, Breed, breed, breed, breed, breed.

She was only human, so it did not take long to catch up to her. Her heavy panting grew louder as he came nearer. The heady scent of fertility permeated the air.

Then Inuyasha's aura flared straight ahead. And it was downright demonic.

He wanted to steer clear, certain he knew what was happening.

But Rin's scent was also in this area.

Panic overtook his beast. Had Inuyasha lost himself to his demon in the heat of lust? He was not wearing Tessaiga when he came out, so it was theoretically possible. But Inuyasha had so little control over that demon. Would he go after any female in heat in that state?

No, he tried to reassure himself. He is mated. He will not stray.

But demons were primal, primal things, and Inuyasha went mad in that state.

And then a cry pierced his heart.

"Ah, Inuyasha!" Rin screamed.

Sesshoumaru's mind blanked with only one need: Protect my mate!

He shot forward like a missile, flying unerringly towards the confluence of the scents. He burst through the brush with a snarl.

"Sesshoumaru!" Rin cried out.

He tore off the blindfold and raised his claws, ready to fight his brother to the death.

Then he froze.

Inuyasha's eyes were indeed a red to match his own, but the legs wrapped around his naked waist led up to a skirt that flared out around the hips.

Kagome stared out from under Inuyasha in abject horror, her eyes flying from him to her left. Sesshoumaru then pivoted his head to find Rin standing on the edge of the clearing, her back to her in-laws as she glanced side-long at Sesshoumaru from underneath the hands plastered to her face.

Slowly, Sesshoumaru edged towards Rin, never taking his eyes off the threat that was his brother. It didn't matter that he was balls-deep in Kagome at this point. Rin was a fertile female within range—and Sesshoumaru didn't know what to expect from his brother's demonic side.

Once he reached Rin, he turned his back to his brother and wrapped his arm around his mate, pushing her towards the edge of the clearing. As they left, Inuyasha chuckled lowly and murmured to Kagome, "And you said he was more turned on than I was. Guess he wasn't all that interested in Rin, huh?"

Sesshoumaru froze. No one maligned his desire for Rin.

All of the sudden, he tore his fur off his shoulder, threw it at the nearest tree, and then slammed Rin face-first into it.

"Oof! Sesshoumaru, what are you—gah!" Rin cried out as he yanked her leggings and underwear down. He felt his brother's and Kagome's eyes on them but didn't care.

Because that was the point. He would show his brother just how interested he was in Rin.

He yanked on the ties of his hakama and let them fall, then pulled Rin's hips back and rammed into her from behind. He snarled in satisfaction as he felt her walls close around him, and she screamed at the sudden invasion, though he muffled it with his fur.

"Holy crap, he's huge," Kagome gasped unabashedly, her eyes wide and watching.

Inuyasha growled. "Kagome, are you getting turned on by him?"

Sesshoumaru threw a smug smirk his brother's way and adjusted Rin's hips to change the angle as he slammed into her again. She moaned, and he knew she couldn't help herself. "You may have had a head start…but I will make my wife come first," he said.

"Like hell!" Inuyasha spat, pushing Kagome's legs back and thrusting into her. Suddenly, Kagome wasn't focused on them anymore as Inuyasha tore open her blouse and attacked her breasts with his mouth.

Rin's core clenched against him, and he looked over to find her face half-hidden in his fur as she peeked past it towards Inuyasha and Kagome. Her face and neck burned bright red, and she clutched his fur like her life depended on it.

"Rin, your focus should be on me," he growled, slamming into her. He hiked up her shirt and sports bra until they rested above her breasts. Her grabbed the mounds and rolled them in his hands.

She moaned, and when she looked back at him, her eyes were glassy. "Remember…how I told you…what I've seen…on the internet?" He nodded. "It's like…watching porn on there…but live!" she gasped as he hit that elusive G-spot he had made it his mission to always find.

He stopped thrusting and leaned against her back, snaking one of his hands down to her clit and dragging his finger down her slit. She whimpered. "But you are not attracted to him…correct?"

"He doesn't have stripes," Rin huffed as Sesshoumaru slowly circled her clit. "I like tracing stripes."

"Go on," Sesshoumaru murmured, his pride and his cock inflating with the words.

"He's not as tall. I like how you cover me completely."

"That's right," Sesshoumaru murmured, bending over to lick her neck and then clamp his jaws around it, lightly teasing her with his sharpened teeth. She shivered, prey caught in the predator's grasp, and his demon preened.

Of course, their words did not go unnoticed by Inuyasha.

"Hey Kagome, do you like stripes?"

"T-These are cute," she gasped, running her thumbs along the markings that had appeared under his eyes in his demonic state. "But I like to make my own." She dragged her nails over his back, and Inuyasha's hips stuttered.

"Oh yeah?" he hissed. "And how big do you like 'em?"

"What are you saying, big boy?" she asked, reaching down to touch their joined parts. "Any bigger, and you wouldn't fit."

He laughed. "I meant my height."

"I like that you're the perfect height for kissing," she murmured, pulling his head down and locking lips with him. They gyrated against each other for a moment before Kagome tore away and Inuyasha started kissing a path down her chest. "And you're also the perfect height for this." She jutted her head forward and bit one of his silver ears. He yelped, his hips jerking into her.

"Oh," Rin groaned, still watching. "But I have to admit…the ears are kind of hot."

Sesshoumaru growled. "You would rather I have the ears of a mongrel?" He pinched her nipple and pressed his claw against her clit, eliciting a sharp cry from her—pleasure tinged with pain.

"O-Of course not. I love your ears," she panted, pushing her hips against his, trying to get him thrusting again. "They're so pointy. You know…I like…pointy things," she said, rolling her hips again. Sesshoumaru grunted.

He was getting close. But he needed to make Rin come before Kagome did.

"You know what else I like?" Rin whispered. Sesshoumaru bent his pointy ear to her lips, wondering if she'd bite it like she had on the course. Instead, she hissed, "I like it when you knot."

Sesshoumaru's blood roiled. "You mean you like to be bred."

"Oh yes," she breathed. "Breed me."

"I always intended to," he said, pulling out and flipping her around. He hiked up her legs around his waist and pressed her flat against the tree, making sure his pelvic bones ground against her clit as he jackhammered into her.

"Yes, yes," she hissed. His cock swelled, stretching her insides, and she groaned. "Oh gods, so big."

Yes, his demon purred. Shout it loud so Inuyasha and Kagome can hear.

"Oh gods. So close! But…can't handle it," she gasped.

"You can," he grunted. "You will."

"Kagome, come on," Inuyasha growled as he thrust.

"Don't…rush…me!" his wife hissed.

"Harder!" Rin cried.

"Faster!" Kagome commanded.

Sesshoumaru suddenly grabbed hold of Rin and leapt into the air. Rin screamed as the force of the jump sent his cock plowing deep into her furrow, and her entire body clenched around him, shuddering with her release. The pressure on his cock proved too much, and his knot swelled. He froze in mid-air as he jettisoned his load into her, clutching her tightly against his chest. Kagome screaming her husband's name and Inuyasha's roar were background noises he largely tuned out.

After several seconds, Sesshoumaru slowly lowered them to the ground, careful not to jostle Rin as he still remained locked within her womb.

"Damn…talk about coming down from an orgasmic high," Kagome mewled, her head flopping over to look at them. "I wanna have sex in the sky…."

Inuyasha huffed, pulling out and rolling off her to rest at her side. As he looked up, he tilted his head. "…Is a tree good enough for you?"

Kagome considered. "Yeah, that'll do." She looked back over at Rin. "Wow, you really like to keep a grip on him, huh?"

"Kagome," Rin groaned, hiding her face in Sesshoumaru's chest. She took the opportunity to lick his nipple, and his swollen cock twitched again inside her.

"Come on, Rin. We've just had sibling orgy. It's not like it can be anymore awkward."

"It's not me," Rin muttered.

"What's that?" Kagome asked.

Rin cleared her throat, still not meeting her sister-in-law's gaze. "Um…he's the one with the grip on me."

Kagome laughed. "Oh, so he doesn't want to be let out of the doghouse, huh?"

"More like…he can't," Rin answered.

"Say what now?"

Sesshoumaru sighed. And Kagome thought this couldn't be anymore awkward.

When Sesshoumaru's knot finally loosened and the orgasmic haze had cleared from the four's minds, proper embarrassment set in. They all put their clothes to rights with their backs to each other and then went their separate ways in silence. Their usual family dinner became a leftover dine-and-dash, with the parents citing various excuses as to why they couldn't eat in the dining hall that night.

The next day, Sesshoumaru and his family went about their normal morning routine. He and Rin avoided the obstacle course and the grove of trees on their walk.

Sesshoumaru did not cross paths with Inuyasha until he was on his way to the arena for the girls' morning lesson. The second their eyes met, the two of them whipped their heads away from each other, and they studiously ignored one another the rest of the way.

When that long, silent walk finally ended, Inuyasha scratched his head and looked around to make sure the girls weren't within earshot. "Look, we're being more awkward than usual, and if we keep this up, the girls are going to badger us about the reason until I cave and tell them. So can we just agree yesterday was a fucked-up, one-time deal where we got carried away and then never speak about it again?"

"Agreed," Sesshoumaru answered.

"Also…I didn't mean to make Rin feel bad. Make sure to tell her she's got a nice pair of tits."

Sesshoumaru punched him in the face. If he was lucky, he'd knock out the recollection of both her tits and that whole affair.

But as fate would have it, the memory of their unintended sibling orgy was destined to live on.


Sesshoumaru had been debating with himself for days now when he should tell Rin the news.

She was pregnant.

It didn't come as much of a surprise, given their breeding orgy in the woods a month prior, but it still took him aback. He first detected the change in her scent while she slept and had been seconds away from waking her up to share his discovery when he stopped himself.

The last time she had been pregnant, he would be away on the warfront for days or weeks at a time, and so she had been the one to give him the news. But now it was different. Did she even suspect it yet? She hadn't made any mention of it to him if she did. But then, it was still early. He recalled Setsuna's tale of Kagome sharing the news of her pregnancy, only to miscarry the baby weeks later. While he was confident his child would take in Rin's womb, the fact was that Rin was older now, even if the Tree of Ages appeared to have reversed some of her signs of aging.

Well, Rin would suspect the news eventually, but in the event that something did happen to their child before she realized it…he wanted to spare her that heartache. So he decided to keep quiet and wait for her to come to him.

He worried at first that the girls would spoil the news, but strangely, they didn't seem to notice (Towa's grin would have given away her knowledge instantly). Perhaps their noses weren't as attuned as his, or perhaps they just didn't realize what it was they were smelling. It was still subtle—something he could only smell when his nose was pressed to her skin.

But all that changed one morning as they were heading to the dining hall for breakfast. As usual, Rin and Kagome went to prepare breakfast while the girls were doing their morning training, so Sesshoumaru accompanied his daughters over after they showered. They found Inuyasha talking to Moroha outside.

"Look, just don't say anything to her about yet, okay? I don't want to get her hopes up. …The truth is—"

"I know, Dad. Setsuna told me about it."

"Oh. Well…uh…let's just say that wasn't the first time and leave it there, alright?"

"Oh gosh. I'm sorry, Dad. I promise I won't say a word!" Moroha wrapped her father in a hug that he returned.

"Hey, what's going on?" Towa asked, concern etched in her features. "Everything okay?"

Moroha turned to her cousins with a beaming grin. "You'll never believe it! I'm getting a little sibling before you guys!"

Sesshoumaru tensed.

Inuyasha face-palmed. "Moroha, what did I just get done asking you?"

"I didn't think you meant them!" she protested with a set of puppy-dog eyes.

Towa's own eyes had stars in them. "Really? Oh, that's great news! I'm not even jealous, because I'll still get to play with the baby, right?"

"You know it!" Moroha answered with a high-five.

"You makin' promises about someone else's kid, Moroha?" Inuyasha grumbled.

"Congratulations, Uncle," Setsuna interrupted, going over to hug him.

"Ah, thanks, kiddo," he answered, ruffling the top of her head, at which point she glared lightly at him. Sesshoumaru's heart clenched. His daughter's interactions with her uncle were so easy. He hoped there would come a day when she was just as comfortable around him. "But it's early yet. Just…keep it on the down-low, okay? I haven't told your aunt, and it'll probably still be a few weeks before we talk about it."

Towa looked back and forth at father and daughter. "Wow…that's a pretty big secret. Are your sure the two of you can keep it?"

"Hey, who kept it a secret that you were playing Setsuna for so long?" Inuyasha griped.

"That's true. Sorry for doubting you, Uncle!"

The girls practically skipped into the dining hall, and as Sesshoumaru passed his brother to enter, Inuyasha said, "You got something to say? Just spit it out."

Had his countenance betrayed him? He could easily brush off his brother, but…his pride wouldn't let him.

"Rin too."

Inuyasha blinked as he processed the words, determining their meaning. Then his eyes widened. "Oh shit, are you serious?" Then his eyes widened in horror. "Wait. You don't think it happened…then?" he asked in a subdued voice.

Sesshoumaru frowned. "The timing is…suspicious." But they wouldn't know for sure until a doctor came to check on them.

"I swear, Sesshoumaru, if those kids are born on the same freakin' day—"

"Breakfast is ready!" Kagome called, waltzing out from the kitchen. Was it his imagination or did Kagome seem particularly bright that day? As soon as she had set her tray down, Towa attacked her with a hug.

"My goodness, what's this?" Aunt Kagome asked.

"Just wanted to say good morning," Towa sang. She pulled back and beamed at her aunt. "You look lovely today, Aunt Kagome. You're positively glowing!"

Kagome's cheeks went pink. "Oh Towa, that's so sweet!" she giggled, hugging her back.

"Good morning, Aunt," Setsuna said, coming up and giving her a hug as well.

"So much affection!" Kagome laughed. "What's going on?"

"Do I get any?" Rin asked coming out of the kitchen with some bowls.

"Of course!" Towa exclaimed, waiting until Rin had deposited her load before pouncing on her. Towa appeared ready to pull back but then she paused and sniffed her mother's neck. Sesshoumaru tensed, already knowing what was about to happen.

"Towa, what did I tell you about smelling me?" Rin grumbled, trying to pull away.

But apparently, Towa had scented what she needed, because her mouth dropped open in glee as she turned to face her sister. She stepped over and whispered to Setsuna, "Mama's pregnant too!"

"What now?" Moroha asked from a meter away, her demonic hearing picking up the words just as well as Sesshoumaru's had.

Setsuna's eyes widened, and she immediately went to sniff her mother under the guise of a hug.

"What is going on with you two?" Rin asked, shooing them into their seats. "You'd think I smell like dog treats or something."

Towa was practically bouncing in her seat, and Sesshoumaru leveled her with a look telling her to keep quiet. She bit her lip, but even that couldn't contain the smile. Setsuna just looked dazed. Moroha was taking turns looking back and forth between her parents, Rin, and Sesshoumaru, the gears of her brain obviously turning.

"Okay, what it is?" Kagome asked. "The lot of you are acting really suspicious."

Sesshoumaru closed his eyes with a sigh. Of course the secret couldn't last long once the girls found out.

"Don't pay attention to them, Ma. They're just being weird," Moroha answered in a voice that sounded too casual before stuffing her face with an egg omelet. Sesshoumaru was impressed that of the three of the girls, Moroha was being the most levelheaded and sensible.

"Somehow, I don't believe that. Inuyasha, what's going on?"

Inuyasha promptly copied his daughter, stuffing his face with rice to keep from answering.

"Inuyasha," Kagome said in her warning tone. She gave him a withering stare. He swallowed down the last of his rice with an audible gulp.

Sesshoumaru wasn't surprised when his weak-willed brother broke.

"You're both pregnant, okay?" he blurted out.

Kagome dropped her chopsticks, and they clattered to the floor as she stared at him, mouth agape.

"I-I'm what?"

"Sesshoumaru, is that true?" Rin asked, turning to him and holding his hand. "I'm also…?"

He nodded.

She laughed and squeezed his hand. "Guess I won't need that pregnancy test I put in this week's supply order. How long have you known?"

"Several days now."

"And you didn't think to tell us, Papa?" Towa demanded with a pout.

He stared down his daughter. "Your mother deserved such news first."

"Obviously," Setsuna added with and admonishing look at her twin.

"But why didn't you say anything to me?" Rin asked him.

Sesshoumaru looked over at Kagome, who still appeared to be in denial.

"Are you positive?" she asked her husband in a quiet voice.

"Yeah," Inuyasha answered with a soft smile.

But Kagome's lips only quivered as tears filled her eyes. "B-But how? I'm nearly forty—"

"So? Not as if you hit menopause or anything."

"B-But you know the difficulties we've had!" she hiccupped. "I d-don't…understand. How…?"

Inuyasha sighed and scooted over so he could hold his wife. "Look, this is why I didn't want to say anything just yet. It's still early, but…I have hope."

"W-Why?"

Inuyasha wiped away the tears at that trickled down her cheeks. "Call it a gut feeling, but I think that trip to the Tree rejuvenated you in more ways than one. But we'll still take it easy for now, just in case, alright?"

Kagome nodded slowly, a smile finally breaking through her tears. "We're really going to have another baby?"

He nodded and then kissed her.

But while the girls were engrossed in watching Inuyasha and Kagome's tender moment, Rin turned Sesshoumaru's focus back to her.

"I can't believe it. We finally get to take this journey together—the whole way. Are you excited?" Sesshoumaru gave her a kiss that showed her just how excited he was.

And so it was that when the first half-demons and their families began crossing the border on Moving Day over a year later, they were greeted by two families holding picture-perfect examples of how demons and humans could live, love, and thrive together.

Of course, the two baby boys proved the most popular and charming of mascots—both of them having inherited their fathers' silver hair, though Inuyasha's son had brown eyes while Sesshoumaru's sported golden ones as well as a little silver tail (which proved to be an interesting challenge with diapers). The girls were only too proud to show off their new siblings, and Setsuna swore the Relocation Project's campaigns went viral because of a few tasteful social media posts of the boys being their adorable little selves.

Finally, Sesshoumaru could relax on the engawa of the grand home he had built for his family, watching his wife and children play together in the yard as he had long dreamed of doing.

Rin was thriving as both a mother and a businesswoman. Sesshoumaru had legally acquired the land around the Tree of Ages, allowing her to both protect the living monolith and cultivate an enormous commercial garden for her online plant-selling business. The digital nature of her shop gave her the opportunity to dive more into social media, and she shared videos of plant care and gardening how-tos that gained a substantial following. (Her famous child helpers may have had a part in that.)

Towa, Setsuna, and Moroha not only continued their studies but dove head-first into their roles as ambassadors for the Relocation Project, helping to see their new neighbors settled and organizing meet-and-greets as well as other events. When Rion moved in, they welcomed her into their little gang with open arms, and she took joined their efforts.

Kagome, who had been bereft of raising her child the first time, committed herself fully to being a mother, not wanting to miss a single minute with her baby boy. Inuyasha, for his part, proved a very hands-on father and also helped the Zone's new residents start organizing their commerce initiatives.

Sesshoumaru was content to remain in the background, running interference with the Northern and Southern governments as needed. Shiori elected to remain a citizen of the South, feeling she could help the most in government, but she had her own second home in the Zone and unrestricted access. She also helped Sesshoumaru set up the Zone's governance.

As for Inukimi, she chose to remain in the Dog Demon palace, overseeing their territory's affairs. This time, Sesshoumaru did tell her about her impending grandchild, and she deigned to visit after he sent word of his son's birth. He made no mention of Inuyasha's child though, knowing it would not matter to her. But of course, she was bound to find out.

When Inukimi arrived, it did not take long for Moroha to mosey over, carrying her little brother.

"Hey, Granny! I thought I smelled you nearby," she announced as she strolled in with the boy.

Inukimi, who was busy lecturing Rin on proper tail care for her grandson, turned and raised her brows at the bundle in Moroha's arms. "And who is this?"

Moroha blinked. "Didn't Uncle tell you about my little cousin's twin brother from another mother?"

"I beg your pardon?"

Sesshoumaru grimaced. He had told her to stop introducing the boys like that—she had already scandalized half the neighborhood. But being Inuyasha's daughter, she delighted in both a vulgar sense of humor and annoying him.

"Inuyasha and Kagome's son was born the same day," he clarified through gritted teeth. The doctor who had overseen Rin's and Kagome's prenatal care as well as the delivery had joked about menstrual synchrony and found it downright hilarious that after Kagome's son was born, Rin's followed only hours later. Sesshoumaru and Inuyasha hadn't found it humorous in the least. (Though Inuyasha had rubbed in his face repeatedly the fact that his son was born first.)

Inukimi tutted. "I knew you were competitive, Sesshoumaru, but isn't this getting out of hand? There are certain swords with which it is uncouth to duel."

His mother had no idea. And he hoped she never found out.

THE END


AN: Hope the sibling orgy wasn't too weird for you! Again, I was aiming for humor with a side of sexy this time, though I seriously debated/struggled with this idea—but hey, it's Spice Week, and it's the time for trying things, no? 😆

Anyway, thank you all so much for joining me on this somewhat spontaneous journey! I really appreciate all the lovely feedback, and I hope this answered some lingering questions you all had from the end of The Wall. Hope to see you again!
