A/N: Hey! I'm so excited for this chapter! You know what? I think I'll be extending this fic at my leisure. I really love this. I'm glad you all are too. This is by far the most effort and length of any chapter I've had so far. A little treat for you guys because I have been a butt by making you wait so long. Also, there's a lot of explaining because I just wanted Fionna to know all about what she was getting into, so I know it's really wordy. Umm… Tell me what you think! Here we go….

*Two Days Later*

-Flame Prince arrives at the tree house to take Fionna to the Fire Kingdom-

"Flame!" Fionna cried, throwing herself through the front doorway and into her boyfriend's arms. Laughing, the prince kissed her hair, free from any bunny-hatted restraints. She knew Flame Prince was coming over, so she quickly took it off and ran a brush through her tangled hair. She knew he liked it when she let her hair down, and since they hadn't seen each other, Fionna figured she'd indulge him.

"Hi, Fi." He smiled, stroking her hair gently. "I see the Flame Shield is still in effect. Flambia told me that she performed a more intricate incantation. Apparently, this one lasts a few weeks."

"Really? That's—" Fionna's thought was cut off by Cake's throat clearing behind her. Reluctantly, Fionna turned to face her sister, shifting from one foot to the other. "Uh. Flame's gonna come in for a bit and then we're gonna go to the Fire Kingdom." She said uncomfortably.

"Hi, Cake." FP said in a well-rehearsed, diplomatic princely voice.

"Um… I'll go get some stuff…" Fionna said quietly, closing the front door and quickly climbing the wood ladder to her shared bedroom. Cake narrowed her eyes at the prince, who simply snorted and sat on the couch. The heavy atmosphere was quite palpable.

"I don't know what you're planning to do tonight, but you had better keep your fiery mitts off of Fionna." The cat hissed.

"Ha. And what if she doesn't want me to?" He antagonized smoothly, raising an eyebrow at the now puffed-up cat. He could be... the "bad guy" when he wanted to.

"She doesn't know what she wants! She's seventeen!"

"It seems to me like the only one who doesn't know what Fionna wants—is you." Cake sputtered angrily, searching for something smart to say. "Now listen. We need to start getting along. It really hurts Fionna when you two fight about us. I know you still don't like me for whatever reason, but you need to know something: I'm serious about Fionna. She's everything to me. I will do anything in my power to protect her and make her happy for as long as I can. If she ever comes to my castle crying because of you again; you won't be forgiven." FP growled sinisterly, maintaining strict eye contact with Cake until Fionna re-entered the room.

"Um… are you guys okay?" She asked tentatively, grip tightening on the duffel bag she held. She looked between the two worriedly, eyebrows knitted together. "I… I'm gonna spend the night again, so—don't wait up!" She said in a rush, avoiding Cake's death glare. The Prince stood and his expression transformed into cool neutrality.

"So long, Cake." The prince grinned, taking one of Fionna's hands into his own and leading her out the door.

-Arrival at the Fire Kingdom Fionna and Flame Prince stand in the stairwell to the first floor, on the way up to the bedroom they would share-

Flame Prince stopped Fionna, leaning against the railing and drawing her close. "Truthfully, I'm a bit nervous." He said to the girl, meeting her gaze.

"You're gonna tell me about Tier 15 now?" She asked.

"I wish you wouldn't call it that." He murmured, squinting down at her.

"What should I call it then?"

"Well, it has many names: coitus, intercourse, sex. I think the one I like the most is 'making love'. It's a really special thing." Fionna blushed vividly. Love, huh? "Although, I read that there was a time when people would do it left and right; sometimes for no reason at all. I think that if you do it like that, then it's just…"sex." Meaningless. From what I've heard, from my parents and from books written before the Mushroom War, it's... an extremely profound and important thing. But, basically, people do it to conceive children—procreate."

"What?! How?" The innocent blonde marveled. Flame Prince grimaced and his flame grew brighter. This was entirely too embarrassing.

"It's—a lot to explain… Cake, never...? Uh—maybe I should show you some of the pre-war texts that were salvaged before we get into this. Though—" FP squinted again, getting lost in his thoughts. "I'm not entirely sure that we could even inter-species procreate. But then again, Lord MoChro and Cake had kittens a while ago, so…hmm…"

"Well is there a way to stop it? I mean… just in case? I'm not really looking to have kids right now," She pouted.

"Ah—yes, actually. Back in the old days, there were many forms of what was called "contraception" for human men and women. Some of the technology barely survived the war and was eventually engineered for all new species that came after. However, hope was held for the continuation of mankind, so contraceptives were again manufactured for fear of another instance of over-population. It's a little pill that can stop reproductive processes in one use. We actually have some here, which is convenient for us. My parents own one of the old factories here in the Fire Kingdom It's on palace grounds. Would you like to go now?" Fionna smiled and nodded.

"Yes."

OoO

Fionna and her prince had returned from the lab hand in hand and walked into the bedroom. In the lab, while Flame Prince had rummaged through the many cabinets looking for the drug, Fionna had picked up one of the books on sexual intercourse the prince had brought to her upon arrival, and was able to read a bit about it. She learned how babies were made, and what the act of sex entailed. The book had said things like: sex was supposed to be "pleasurable," which confused Fionna, because the book also said that it usually hurt when a woman had sex for the first time. Both parties had to be sufficiently sexually "aroused" in order to engage. It also mentioned the different ways to excite both sexes. Kissing, touching, etc.

Sitting in a stray chair reading and gazing upon many pictures gave her an odd tingling sensation in her lower half. She crossed her legs, squirming in her seat. Gaining this plethora of knowledge made her blush uncontrollably. Flame Prince is gonna do those things to her? His… thing is gonna do that? And he was gonna touch her in her most private places. The only hands that had ever touched her body were her own, and it was nothing special. Every so often, she'd peek over her book to catch a glimpse of him. Her eyes would unwittingly fix on his groin, staring hard. Eventually she'd get ahold of herself and snap her gaze back to the pages, trying to ignore the burning of her face and the pounding of her heart.

By the time they'd finished up in the lab and walked back up to his room, Fionna was terribly nervous.

Flame Prince handed her a little pink pill in the shape of a heart. She threw it back and chased it down with water he'd offered her.

"It takes approximately 15 minutes to take effect." He said, strolling over to the bed and taking a seat on the flame-resistant, king-sized furniture and holding out his hand. She timidly stepped closer and sat next to him on the soft, high-end fabric; taking his outstretched hand. FP threw his legs onto the bed, shifting so that they lay in front of him. In an attempt to downplay her nervousness, Fionna boldly crawled up onto his lap; their legs forming a right angle. She detached her left hand from his, letting it rest on his shoulder. He took her right hand and laced their fingers together, kissing the girl's knuckles and relaxing her momentarily.

"Relax, Fi. Normally, people make love when they're in love. It's one of the only ways to completely bond you with another person. Well, it's the secondary way, I should say. Naturally, marriage is the first. But... Are- Are you… In love with me Fionna?" He asked her finally, eyes brimming with concern and anxiety at her potential answer. Fionna's heart beat faster, and all of the feelings she had been holding in for months tumbled out as she confessed.

"I really hope so." Taken aback by her response, FP flinched back, surprised. "Otherwise… How would I explain the fact that I always want you to around me? Or how I love it when you touch me, even when I used to get burned; and that when you do, it makes my heart beat too fast. How could I explain that you're all I think about, before I go to sleep and in the morning after I wake up? It's like my chest is so full that my heart forgets to beat sometimes.. Whenever I get all lonely about being the only human in Aaa… When I see you, I feel so much better. Even though you tease me a lot and annoy me and we fight, and even though you and Cake don't get along at all, I still feel this way. When I'm with you… I feel like I can beat anything. When I'm not, I feel like anything can beat me. If I'm not in love with you, then something really is wrong with me. And if I am—" Fionna's left hand moved up to the prince's incredulous face, stroking his cheek gently. "then I'm completely crazy." She whispered sheepishly.

In one swift movement, Flame Prince had Fionna pinned down by her arms, his flame burning bright as he breathed heavily. She stared up at him with wide eyes, surprised but not startled.

"Wh- Flame?" She uttered.

"Say it." He huffed.

"Say it…?"

"Tell me... that you love me." His eyes probed hers desperately. The adventuress gulped. It would've been beyond embarrassing to be pinned down like this, forced to spew her guts, but it was her Flame Prince, and she… she loved him. No one in the world could make her heart race, fill her stomach with butterflies or make her knees weak like he could. It was maddening being so out of control, but—as long as it was kept between them, she didn't mind it. In fact, she needed to tell him. She had to, just as badly as he needed to hear it. After all this time avoiding and being scared of the magnitude of her own feelings, she wanted to relax. He had to know just how much he meant to her.

"I- I love you." Flame Prince gave the blonde a quick kiss and pulled back, eyes glowing even brighter than his body.

"Say it again," he murmured, ducking down and kissing her warm cheek softly.

"I love you." His large hand slid up her right forearm and their fingers locked together.

"Again." He whispered, lips now at her ear.

"I love you, Flame. Really." She whispered back.

"I'm—I'm so glad. Fionna… I've loved you for quite a while. I was afraid—that I'd never get to hear you say it." An unexpected giggle erupted from his love.

"You donkus. I would've sorted it out eventually." She ran her free hand through his mohawk. "Here—let me up."

Flame Prince looked down and blushed a vibrant red. "Oh—sorry about that." He lifted himself and sat back on his heels. Fionna sat up immediately, allowing FP to tug on her hair. The wavy blonde tresses bounced about, spilling around her face and down her back, stopping at her waist. Ignoring the heavy locks, her hand reached out and flattened against the fiery boy's chest.

"I want…" She averted her eyes bashfully, heat creeping into her face. "I want you to—m—make love to me. Right now." Her hand squeezed his vest. "Now that I can finally touch you… I wanna be close to you. Being away from you these past few days… I definitely didn't like it. And... I've been feeling things too, when we're kissing. I didn't really understand it, but I think I do now. I wonder when it came to the point where I couldn't be without you?" she mused.

Flame Prince took in the beauty before him, hardly believing how lucky he was: glossy, full-bodied blonde hair that fell into wisps around her normally pale, now-red face, accentuating her big, blue eyes. The bluest, coolest blue orbs he'd ever seen, and the complete opposite of his vivid maroon. Her long eyelashes fanned as she blinked slowly, waiting for a response. He simply stared, gazing at her cute little nose, above a pair of supple lips that seemed to meld perfectly to his own. FP smiled, heartbreakingly happy that she was his for the night. Finally acknowledging her request, he nodded and placed a warm hand over hers, helping her undo one of the buttons. He'd seen her reading the books intently. She had the knowledge. Now all she had to do was say "OK."

"I'm yours." He said softly. Fionna deftly unhooked the rest of the buttons, and then watched him shrug out of the vest, tossing it away and going for the buttons on his white dress shirt. She eyed him wordlessly, eyes feasting on the newly exposing skin. He had a lean but hard stomach, and strong, toned arms. She scooted closer to him, ghosting her fingers down his chest. The sensation made him close his eyes and sigh. His light was so brilliant all of a sudden, it almost hurt to look. He was so handsome.

"Flame?" Fionna spoke quietly, snaking the hand she had on him around his waist, lightly scratching at his back, making him shiver. He partially opened his eyes, the half-lidded maroon lights observing her gorgeous blue ones. "Can I kiss you?"

"You don't really have to ask." He chuckled, leaning forward and capturing her lips. She pulled back, licking her lips.

"That's not what I meant." She muttered, pushing his chest so that he stumbled off his ankles and onto his back, propped up by a few pillows. She crawled up onto him and straddled his waist, throwing her mane to the side and holding it so that she could plant a kiss on his collarbone. Her lips traveled to his chest, then further down. Because she was sitting high on his waist, she shifted, wiggling her pelvis down and over his hips in order to get her kisses further down. Due to his bright skin, Fionna had to squint while she kissed down to his navel, inciting another sigh from her prince.

One of his hands that lay on her waist brushed up to the hem of her shirt and he tugged on it; clearly wanting her to remove it. She felt a small bump form beneath her, realizing now what it really was.

Fionna's cheeks flushed a bright red, her eyes sweeping over his own slightly flushed face before pulling her tight blue shirt over her face and hair, tossing it over to join the prince's discarded clothing. The girl wrapped her arms around her own waist self-consciously, unwittingly accentuating her ample chest and wondered briefly how she could have aroused him in less than 5 minutes. Flame Prince gulped and sat up, using one of his large hands to steady Fionna so that she wouldn't fall. He gently laid her down, backwards on the bed and took up a position next to her. He buried his head into her soft yellow locks, inhaling the strong scent of the forest; a smell forever embedded in the long tresses. His lips made their way to her ear.

"Can I touch you?" He asked intimately.

"Where?" She squeaked, turning her head toward the sound of his voice. He looked up and gave her an endeared expression, touching her face briefly before fluttering that same hand about the lowest exposed expanse of skin on her torso: the beginning of her hips.

"Here," he murmured quietly. "You're so soft..." the boy marveled.

"Shut up," she grumbled. "Where else?"

Flame Prince grinned and moved his hand up further over her toned stomach to just under her breasts, and her skin rose into warm goosebumps. "Here"

"Uh-huh" She whispered, every breath coming up short. She was absolutely sure he could hear the pounding of her heart in her chest.

"Or maybe… Here?" He rumbled in a low voice, sliding his hand under the wire of her bra and gently gripping the swell of her breast. Fionna's hand went up and clutched his forearm. "y-yes." She exhaled quickly, soon inhaling just as quickly.

"Definitely here." He pinched her nipple teasingly, twisting it a bit.

"hah." She gasped, kicking her head back.

Fionna enjoyed the unfamiliar sensation thoroughly, feeling her skin heat up. "Take it off." She barked out.

"What?"

"My bra. Take it off." She arched her back allowing for easy access to the back clasp.

He obliged and unhooked it after a bit of trouble; pulling the straps from her shoulders and the entire thing off, disposing of the white, blue-trimmed fabric swiftly. Her breasts bounced out and FP felt the flame in his pants increase.

"Pants." She panted.

"I don't—maybe I should wait."

"Why?" He blushed profusely.

"Well I'd—like to foreplay a bit, and if I take my pants off, I might get—too excited. I don't wanna push you." Fionna rolled her eyes and stuck out her tongue.

"Not fair," the girl huffed. He gave her a fast smile and dipped his face to one of her breasts, kissing it and flicking his tongue over the rosy tip.

"Nnnn." Fionna squirmed. Her body thrummed and tingled all over. She noticed that her underwear felt damp, and she guessed that it was the natural lubricant she'd read about. Her inner thighs trembled madly, which puzzled her. She wasn't sure what she wanted him to do to her. She was afraid to ask. Well, abashed, rather. She rubbed her thighs together fitfully to relieve some of the tension.

"Fionna?" Flame Prince leaned back and peered down at her, concern washing over his features. "What's up?"

FP looked down at his love, chest heaving slowly, hips wiggling and legs twisting over one another. She stopped her ministrations and propped herself up on her elbows. The heat intensified on her blue-tinged cheeks. Flame Prince tried not to throw himself onto her.

"I feel—strange. Hot. Not because of you! Just—in—places." She gasped, trying to catch her breath. Her eyes flitted to her lower half before coming to meet his again. Her boyfriend chuckled, blinking back at her in surprise.

"Are you telling me you're aroused?" He asked, cocking his head to the side and smiling when she flinched in embarrassment. She was too adorable.

"I—I don't know." She admitted, now refusing to meet his eyes.

"Don't be embarrassed. Actually I—me too." He stated sheepishly. Fionna's stare traveled to the front of his black slacks, tightened around his crotch. She gazed hard in amazement. the small lump had certainly gotten bigger. Had she really had that much of an effect on him?

"I wish you wouldn't stare like that." He muttered, only to have the statement fall on deaf ears.

"Your—penis. It got—bigger?!" FP's flame burned bright all about his face.

"Ah—well, yes, that's the idea," He was cut off by the innocent blonde, whose eyes had gone big as the moon. She was too cute. How was it fair for her to be this cute? She sat up quickly on her knees, placing her hands on her pale thighs.

"Because of me?" Her eyes twinkled with wonder. Flame Prince's lust grew watching her breasts bounce about upon her moving.

"You're really impossible." He ignored her question and took hold of her skirt. "Off." He ordered.

Fionna felt a rush of heat as she sat back on her butt and did as she was told. "What're you gonna do?" She murmured apprehensively, putting her knees together shyly. Only her pale blue panties remained.

"Lie down." She obediently did so, eyes never leaving his. He shifted onto his side lying next to her and placing a hand on her left thigh Fionna lifted a hand to FP's face, savoring the warm, pleasant feel of his skin beneath her palm She loved being able to touch her boyfriend. Her legs relaxed and she kissed him, allowing his fiery tongue entrance into her mouth. It was an odd yet familiar sensation, and she welcomed it.

Flame Prince's hand slowly stroked up Fionna's creamy thigh to the hem of her panties; where his index finger drug under the elastic painfully slow, teasing.

"Can I?" He rumbled against her lips.

Fionna nearly missed the hand against her, but once she noticed it, it was impossible to ignore.

"Can you what?" She whispered, hungrily kissing him once again.

"Touch you here?" He whispered intimately, running his tongue along her bottom lip. In response, Fionna's thighs crashed together instinctively. Her heart thumped in a place nowhere near her chest. "Trust me." He purred over her cheek, biting it gently.

Fionna's legs went slack as she melted, completely falling under the spell of his tone. His hand traveled beneath the pale blue fabric and a few fingers slipped from top to bottom, running over many things. Fionna gasped loudly. "It's so... wet." Flame Prince marveled, twirling his fingers in circles.

"Ah!" She moaned, her hand falling from his face to her own mouth, surprised at the sound that just flew past her lips.

His eyes shot up and he stopped his fingers. "Am I hurting you?! Does it burn?!" He asked in a frightened tone, searching her flushed face for signs of pain. The blonde averted her gaze bashfully.

"No… I— it doen't- it feels good." She said quietly.

"You like this? I mean, according to what I've read, there's supposed to be a sensitive place here…" Flame Prince's fingers groped about gently, oblivious to what he was doing to Fionna. Her chest rose and fell as desire pumped through her bloodstream. This feeling… It was…amazing. Impossible to describe. All she could do was whimper in helpless delight, it was nearly unbearable.

"Nnnn! It's all sensitive, you—idiot!" She cried, tilting her head back. Flame Prince watched her writhe in pleasure and became extremely excited.

"Open your legs more." He said heavily.

"It's…embarrassing… I've never-" She squeaked, allowing him to spread her legs for her. He stuck a finger into her core, using his thumb for continued stimulation; delighting in her delicious vocalizations.

"Ah~ Flame!~~" She arched her back in an effort to get closer to him. He kissed her ravenously, enjoying her breathlessness. Her hand came up and tangled in his strangely tangible fiery locks, deepening the already hot kiss. Fionna's right leg curled around FP's thigh. He growled and his teeth fell down to her neck, grazing the soft skin there and making her cry out. He tugged his hair to one side; which he liked. A lot.

"Keep doing that." He spoke thickly.

"What, this?" She ripped his hair to the right and he grunted in response. Fionna giggled.

"You like that?" She asked, giving him an amused look.

"You're one to talk." He began to jerk his fingers, causing her to jerk her own grip on him. They moaned at the same time and FP smirked, withdrawing his hand to show her the wetness on his fingers, to which she blushed.

"D—doesn't that hurt?" She wondered.

"Not really, I mean, it's not exactly water and I haven't burned it off. So—it's weird. She shifted bashfully under his gaze and felt a hard bump on her thigh. Remembering what it was, she slipped her hand down and pulled on his belt buckle. She bit her lip and met his eyes, holding them from under her long eyelashes.

"Now it's your turn to take it off." She murmured... seductively? Earning a shudder from her boyfriend and causing a blush to break out over his face and ears.

She undid the belt buckle without much difficulty, moving her hand beneath the pants and boxers, gripping onto him. It was then she felt how scorching hot he was. Well, with her flame shield, that is. He definitely burned the hottest here. She stroked it within the pants, watching the range of emotions on his face: shock, embarrassment, and eventually, lust. His eyes snapped shut and a low growl ripped from his throat. "Is it gonna fit? I mean, it seems kinda...big…" The prince's eyebrows knitted together over his now half-lidded maroon orbs.

"Glob Fionna, you're really trying to kill me, aren't you?" He gently pushed her hands away in order to tug his pants down, followed by his boxers. His member sprung out, and Fionna took in the bright, pulsating orange rod, sticking straight up. It looked warm and oddly inviting, so she pushed away the thumping of her heart and reached out to touch it again, to make him feel good. His hand shot out and grabbed hers gently in mid-air. The blonde's eyes opened wide and she gazed up at him.

"Did you…Dislike this?" She asked innocently, eyeing his red face, her own visibly falling. Flame Prince's heart beat erratically, and it hurt. Watching her face fall made his heart ache. He'd hurt her feelings.

"Ah… Rather than dislike…" She raised her eyebrows. "I've never felt anything quite like this, despite what I would do on my own—" Fionna's mouth fell open. He did that sort of thing?! His face was exploding fire. She looked down at his hand. "Oh! All of a sudden, I—I'm sorry. I reacted without thinking." He snatched his hand back. "You just surprised me, is all." Sitting back on his palms, he took several deep breaths. "You can touch me if you like." He muttered shyly, looking away from her. Fionna thought he looked very young, despite being one year her senior; and extremely vulnerable. She kissed his cheek softly, and his stiff shoulders relaxed.

She extended her arm once again and closed her small hand around the warm stick. She stroked it slowly. It appealed to Fionna in a strange way, mesmerizing her. She quickened her pace, observing FP's closed eyes and quick breathing.

"It's pretty." She blurted dumbly, regretting the stupid sentiment immediately, dubbing it as quite possibly the worst, most idiotic thing she'd ever said to the prince. He blushed immensely.

"Honestly, Fi." He whispered, eyes remaining unopened.

"It just came out," she attempted to amend. He smiled, now peering at her through hooded lids.

"It was a compliment, so I'll forgive you." He huffed. "Ah." The prince's head lolled as Fionna's fingers slipped over his sensitive tip. "I think I've reached my boiling point." The adventuress's heart quickened in pace once again as his head lifted and his lust-encrusted gold-flecked eyes seared into her own.

"Are you ready?" He asked, turning onto his stomach.

"For Tier 15?" The girl squeaked nervously. Was it time already? FP took her cool hand and drew it up to his face, kissing it.

"To make love." He mended softly.

"Yes." She whispered back cuddling up next to him and kissing his hot cheek.

"It may hurt a bit." He uttered, turning his face in her direction. Fionna snuggled his cheek with hers.

"I slay monsters for a living, remember? " FP chuckled in response to her giggle. This Fionna was so… different from the usual one and he wanted nothing more than to keep her locked in his room forever. Only he could bring out this side of her. What an amazing feeling! If he was supposed to be "evil," how could he be so hopelessly in love? If he was supposed to be some all-powerful prince about to become King, how could she hold so much control over him without even trying? He tugged her panties down and away from her body, hands trembling a bit. This is it.

The prince climbed atop his small love, heart clamoring in his fiery rib cage. She clutched his back in response, causing him to lay fully on her. "

"Uh.. I've never..." He trailed off, looking extremely vulnerable. And for the first time tonight, like he was unsure of what to do next. She clutched his back in response, causing him to lay fully on her. "It's ok. I love you." She whispered, the words nearly absorbed by the night. His limbs turned to molten lava. Ugh. How can she do that? Make me so weak like this, by uttering one simple phrase? He reached down and led his manhood to her. It took him a few times to find the opening, but rubbing against her only succeeded in heating them both beyond belief. Once finally at her entrance, his hand went back up to her hair, and, resting on his elbows, he pushed in slowly, resisting the urge to groan as her walls closed tightly around him. She let out a sigh.

"Does it hurt?" He asked breathlessly, looking down at her.

"Not at all… It feels… Stretched, I guess." He stroked the side of his face. "Go ahead. I'm fine."

With her encouragement, Flame Prince began to thrust in and out at a steady pace, dropping his head to tongue and bite her neck. She moaned and her hand fell to rest by her left ear. "Haah. It's so… inside… Hah… Oh…" The prince groaned in a low, desperate voice. "I love you too, Fionna the Human." He nibbled at her earlobe now, and, movements never ceasing, slid his right hand up to entwine their fingers. Fionna's breathing became irregular, along with her boyfriend's.

"M—more." She whispered urgently without shame, closing her eyes to her prince's blinding light and tightening her grip on him. She burned everywhere he touched her. She felt like a different person. Glob, it's so hot.

Her mind fell into a dizzy haze; she couldn't think of anything logical, and her brain refused to function properly. Her thighs clenched together, holding her love in between them. "Ah!" Every time he pushed all the way into her she'd cry out. She could barely hear the sweet nothings being whispered into her right ear.

"Fionna—my princess—my queen—I love you so-hah-much—never leave my side-ah-stay with me here, always. Forever."

"Forever." She gasped; the only thing she could say, repeating it like a bird. She threw her head back and whined, feeling her nipples rub against the heat of FP's chest. Oh my… Her nerves were electrified and continuously cracked everywhere her skin was touched. The friction of their bodies caused Fionna to sweat under the flame shield, and her eyes to tear up a bit. She might just spontaneously combust.

Flame prince hardly noticed the sting of these things and simply ground against the girl beneath him.

"Ah! I—it's too much. I can't—I—hah!" Fionna whimpered desperately, unable to finish her thought.

"What's that?" The prince asked devilishly, nibbling on her shoulder. She trembled, body shaking heavily beneath her love. She began to feel an unbearable tension build up in the pit of her stomach, and it made her ache all over. Was she exploding?

"What?" he urged, thrusting even harder. The tension mounted, but she couldn't get enough of it, of him, and this foreign feeling that made her thighs quake. She wrapped her legs around his fast hips, bringing them ever closer.

"It's good! So—aahhh!—so good!" She lamented, the suspense was killing her, and she felt completely on edge. Is this insanity? She began meeting his hips with her own, the two eventually falling into a rhythm. "Ohh!" She squealed, her voice extremely high and unrecognizable to her. The tense feeling moved to her hips, prompting them to move faster, harder.

Flame Prince just groaned in response, close to losing his mind. Oh glob. This is… it's insane. I'm gonna...

The next second Fionna climaxed for the very first time, and being unfamiliar with the feeling, it completely blindsided her, causing her to let out a pleasure fueled cry. She shook like a leaf, and unintentionally scratched at FP's back. Unabashed, he kept going, enjoying the slicker inner walls contracting around him and the moans piercing the otherwise silent night. Unlike Fionna, the feeling of imminent orgasm was all too familiar to the prince, and the wait was gut-wrenching. When he finally exploded, FP buried his face in Fionna's thick of hair to avoid being as loud as her, as he knew he'd never live it down. He let out a series of growls and grunts, spurting fiery liquid into her, hearing it sizzle out as it made contact with her inner walls.

To his mild surprise, he didn't go slack, which only ever happened when he had waited too long to relieve himself or when he was extremely stressed. He did collapse, however, resting a bit before asking to go again.

"You can?" His love asked, raising his hand to her lips and giving it a kiss.

"Hey, that's my thing." He answered, kissing her damp cheek. "Yeah. I'm up for it if you are."

OoO

An hour later, both parties lay tangled backward on the bed facing each other, mixed into the flame retardant sheets.

"How are you?" FP murmured, stroking Fionna's face directly in front of his.

"My legs feel like jelly." She admitted sheepishly. "It was hard to relax right after we finished, but… I think I'm okay now. That was…" She trailed off, looking for the right words.

"Well, I can say that it was the most amazing thing I've ever experienced thus far in my young life. I… I never thought I'd be able to get this close to you." Fionna's perma-flushed face darkened in color and she turned it toward the bed, staring down into the fabric one centimeter from her eye. She had somewhat returned to normal and was reluctant to show him her embarrassed face for the millionth time. Flame Prince traced the apple of her visible cheek with two fingertips. "Hey Fi," He muttered, pushing her hair away. The young blonde tilted her head a bit so she could peek at him from the corner of one eye.

"I love you." She lifted a fist and crushed it against his cheek.

"Quit making me blush or I get my sword." She said in a muffled, indignant voice. The prince moved his face closer to hers; his nose lightly touching her red ear.

"Did you forget what I am?" The low voice sent shivers down Fionna's spine and her breath caught in her throat. "I'm the Prince of Fire. Seeing your face get red; feeling the heat—it drives me crazy." The adventuress's fist weakened and flattened out, cupping his face.

"You blush too, ya know. In a way. It's just different." She then felt flames lick up and around her palm.

"Shut up." He grumbled.

"Hey, that's my thing." The girl simply giggled.

"Hmph."

"I love you too, dork." She snuggled his face happily and yawned. "Really." She whispered, eyelids heavy. "I didn't know it was this tiring."

"You're welcome to sleep here, you know." He uttered, his own breathing getting heavier. This is bad… I'm so happy I could die. Nothing else matters.

"Pssh. You act like I planned on leaving. I packed an overnight bag, ya know." FP's chest rumbled as he chuckled. Same old Fionna.

"Sleep, love." He whispered, bringing her closer to his torso and hugging her tightly. He ran his fingers through her long, glossy hair.

"Tell me again." She demanded groggily, rubbing his bare chest with her hand. "I wanna hear it again."

Flame Prince understood immediately what she wanted, as he had asked her the same thing over and over roughly two hours ago, and even in his sleepy state, his flame grew ever brighter.

"I love you, my queen. I'll never let you go." To this Fionna smiled widely, overwhelmed by the warm, fuzzy feeling bursting from her heart. She realized that all of the embarrassing things they'd just done maybe weren't so embarrassing, but instead a staple of their love. She would remember this night for the rest of her life, and she'd never forget the things he'd said to her. It was cheesy, and lame, but… nothing could be more true. She loved him. So, so much. Soon, she was lulled to sleep by his now warm glow and rhythmic breathing. And of course, she dreamed of him.
