A/N: Hey guys! So this chapter is gonna be cute I guess at the beginning and well, it gets quite saucy! Oooooooooooooohhhhhhh Fionna and Flame Prince are getting a little bold! Ahahaha! I'm kinda amping it up here, so let me know if it gets too much. Oh I just love it. Hope you guys do too. Also sorry if Fionna is a lil dumb for a second, but she's new to this! It's got a lot of weird grammatical errors (?) but I think the ideas are still understandable.

*I OWN NO COPYWRITED MATERIALS USED IN THIS FANFICTION*

After she'd spent about three hours feeling sorry for herself on the couch, Fionna slipped her pajamas on in her bedroom and went back downstairs. She didn't feel like bringing Cake down with her. The cat couldn't sleep when the atmosphere was off. That being said, Fionna ended up just falling asleep on the couch, feeling... well, sorry for herself.

oOo

Three hours later, Flame Prince materialized outside of the Treehouse and approached the living room window observing his sleeping girlfriend on the couch. He carefully melted the locks on the window and whispered an incantation to himself to keep from burning anything in the treehouse. He swung both of his legs in, being as quiet as possible. He briefly panicked that the cat would wake up and bust him, so he moved slower. He tip-toed over to the couch and sat down by Fionna's head watching her for a moment. He watched as her brow furrowed and her lips parted, catching some of the stray hairs that fell into her face. He extended a hand and gently brushed the hair away from her face. She was so beautiful to him.

When her eyes fluttered open, the bright blue caught him off guard and his heart skipped a beat. And, oh yeah: he got butterflies. He observed the startled look on her face, which relaxed when she seemingly recognized him.

"You scared me." She said hoarsely. "How are you not melting everything?" She asked groggily, looking around.

"Incantation. I'm suppressing my powers."

"Ohh." Fionna propped her head up on her elbow, blinking to clear her vision while she gave her boyfriend the once-over. "Are you- wearing your pajamas?" She asked him, taking in his plain black t-shirt and light gray sweatpants. He smiled sheepishly, scratching at the back of his neck.

"I couldn't sleep so, I…" He paused, watching Fionna lift herself into a sitting position sluggishly. She looked exhausted. "I came to apologize." She tucked her hair behind both ears and slid off of the couch to sit next to him. She let out a shaky breath, then leaned over and snaked her arms around FP's neck.

"No." She said, eyes pricking with new tears. "Me first." She sniffled, hugging him tightly as he blinked in surprise. "I'm really sorry. Like really." She whispered to him.

"If you doubted me, you should've said so… We could've talked about it."

"It's not that I doubted you!... It just… Made sense when I said it. Honestly, I was just looking for something to say, and I didn't pay attention so I just started rambling, I-." She fell short.

"I'm sorry too." He whispered back quietly. Fionna released her hold and pulled away, staring at her boyfriend with wet and leaking eyes. She ignored the tears that escaped and proceeded to repent profusely.

"I should've never talked about your parents like that. I shouldn't have yelled at you. Glob, I- I just wanted to hurt you! And I- I would never-! But I did, without thinking and i-" Fionna sniffled, touching his face with such tenderness, you would have thought he was made of fragile glass.

"Me either. I just wanted to hurt you in the same way that you hurt me... About my father, you just..." Flame Prince shook his head when he saw his girlfriend's face twist with regret. "I should have been more mature than that. It was cruel. And I know that it was mean to bad mouth your sister. I just... she makes me feel like a monster. And I've felt like that my whole life. I don't want to be the monster anymore. And I love you. Glob, Fionna I love you and it made me boil to see you so upset because of that cat and I. And I felt guilty. Because maybe I'm not right for you... or good. And when you implied that I was dangerous... That hit me hard. Ever since I met you, I've tried to be better, for you, and when Cake, and even you think that I'm dangerous, I feel like everything I've done means nothing. But I know it doesn't excuse anything. I was wrong. C'mon, Fi, please don't cry." He pleaded, lifting a hand to swipe away a tear on her cheek.

For a brief moment, the pain twisted his face, and Fionna cringed. "Stop it." She murmured. "I know it hurts."

"It doesn't hurt me as much as seeing you like this. So you stop." Flame Prince touched his forehead to his girlfriend's.

"I don't think you're dangerous. i mean it. You're not a- a monster... Not bad for me. I've never thought that and i never will. You're- you're everything I want." Fionna whispered to him gently, tears still rolling down her face.

"I must look like a mess," She said thickly. "I'm being such a baby."

"Shhh. You know I think you're stunning no matter what." FP snuggled her wet cheek with his own and played with her hair. "No more tears. Baby." He teased.

"You know I love you right?" She spoke softly, voice barely above a whisper. "You know that?" The prince pressed is lips to her cheek.

"I feel it every day."

"Kiss me." said Fionna as she pushed against him.

"Not unless you kiss me back."

Flame Prince leaned in, kissing his girlfriend square on the lips. He dragged the kiss out, tasting every bit of her. Neither wanted to be the one to break the kiss first, so it deepened, and their tongues now danced together. In an effort to get closer to the prince, Fionna climbed onto his lap. The heat between them mounted, and the adventuress clutched FP's neck tighter. Her heart clamored relentlessly, and she felt so flustered. A second ago, she'd been crying. Crying for hours. But the reality of this whole fiasco made her realize: She never wanted to let go of this man. Her head was so filled with thoughts of him that she sometimes forgot that other people existed. But… She was okay with that. She even felt a bit silly now, thinking that he'd break up with her just like that.

They were so close now, but it wasn't enough. She began to get frustrated because she wanted—just a bit more than she was getting. But they couldn't. Not here at least. Not with Cake just up the stairs. Still... She couldn't stop his name from falling from her lips. "Flame~" She whispered against his lips, breathing heavily. In response, the young man tightened his grip on her hips, pulling her closer. When his teeth grazed her lips roughly, she jumped a bit and squeaked, earning a devious chuckle from the prince.

"That was cute." He muttered, watching the blush break out over Fionna's cheeks.

"Shut it." She gasped before her lips got enveloped again.

They stayed like that for a few minutes, kissing until neither could breathe. Eventually, they broke apart for a bit to catch their breath.

"Fionna." FP grunted, catching the adventuress slightly off guard. "I'm so… turned on." In her haze, Fionna cocked an eyebrow, puzzled at the sudden declaration.

"Huh? What's that mean?" She asked breathlessly.

Flame Prince palmed the back of her neck, forcing their foreheads to meet once again. "It means that you make me like this." He said huskily, angling her head down at the front of his sweatpants, obviously pointing out the bulge.

"It means…That I want to kiss you, to touch you… I wanna make love to you." He looked at her, caressing her bottom lip with his right thumb. "This is what you do to me." He whispered. "You make me burn so hot."

Fionna crashed her lips into his abruptly; heart beating out of control. She shivered, and warmth spread like wildfire between her legs. For some reason, hearing him say those things made her want to attack him. She broke the kiss, panting. "Talking like that isn't fair."

"Does it make you feel weird? He teased.

"It makes me feel…turned on, I guess." She murmured. "Can't—Can't you feel how hot I am?"

Hearing that, Flame Prince crushed his lips to hers hard, running his tongue along the length of hers. He couldn't take it when she said things like that. It wasn't fair how hard it made his heart pound, or, how hot it made him. And she said his words were unfair?! But somehow, he couldn't get her crying face out of his mind. He'd done that to her. Maybe if he was closer; touched her more, she could feel how sorry he was—how much he loved her? The hand on her neck, trailing down her back in non-descript patterns and kneading her hip: I'm sorry. The other, on her face, knotted in her thick hair, then wrapped around her waist: I love you. She shook slightly beneath his touch, and he could tell her skin was warm. Could she feel it? He slowly reached up and unzipped her onesie pajamas, nibbling on her bottom lip.

"Mmm. You can't. Cake is…" She moaned against him, leaving her sentence unfinished. Leaning back a bit, she watched his hand slide into her underwear. He wasn't wasting time.

"Then push me away." He challenged in a low, husky voice. Because unless she stopped him, he didn't want to stop. He moved one finger, stroking painfully slow, and realizing how wet she was.

"Stupid… I can't… I—won't." Fionna's breathing hitched and she looked up at him, shivering. She'd never seen anyone with such a look in their eyes before, not even him. His gaze burned with such intensity and bore into hers so deeply that she could only stare back, momentarily paralyzed.

"I love you." He said thickly, voiced laced with pure emotion. The words fell from his lips and she heard every syllable, right as they were formed. And she felt them, everywhere. Her fingernails began to scratch into her boyfriend's shoulder as the room came alive, crackling with nearly tangible electricity. Little tendrils of energy snapped at their bodies playfully, invisible to the eye. And although there was no noise in the room, the space between them was loaded with sound. Her skin hummed and blood roared in her ears, magnifying the fast beat of her heart. It was so loud in-between them, that she swore she could hear his heartbeat as well. And even with the window open and the chilly night air flowing into the room, she was hot. Her body burned all over, heating her from her toes to her red-painted cheeks; which puffed out almost visible clouds of warmth.

"It's…So…Embarrassing…"—was all she said! It was the only thing she could think to say at a time like this; and don't you dare think that she didn't notice the lame nature of the phrase. But, to be fair, if Cake came down and saw them like this… Fionna'd have to move out for sure. "When you touch me, I get…" Yet again, her words fell away into the varying sounds of the atmosphere.

"It's just me and you," FP whispered, pecking her lips gently. "You and I. Got it?" He asked, searching her eyes. Fionna shook her head, mentally shaming herself for being so easy; for conceding just like that. His velvet words brushed away her insecurity and anxiety, and the girl let out a defeated groan.

"I love you—but you're too reckless." She murmured back, laying her forehead in the crook of his neck. As he touched her, she whimpered and clutched him tighter. Every so often she'd push her hips harder onto his hand, feeling the stiffness of his arousal press into her from just beneath it. The sensation kicked up the beat of her heart, making it harder to breathe steadily. Fionna fell into him, craving his touch. She didn't think she'd wanted his hands on her so much the entire time they'd been dating. She felt glued to him, and she let out a pant. And… She wanted more. Ohh, Glob she wanted it so badly! It had never occurred to her that she could even want another person like this. The feeling was so urgent, and she felt that she just might die from anticipation "Mnn!" her small voice sounded; a small but obvious plea for just a little more. She wanted him so intensely that her thighs trembled ever so slightly and their muscles tightened gently around her love's hand. Her skin flushed with nonstop heat, and down there, she was so—wet. The blonde longed for his lips; to feel them pressed against her ear, whispering into it. But more than that—she wanted to hear that he needed it—needed this just as much as she did. Just then, she felt him thrust one finger into her easily.

"Flame!~" She moaned as quietly as possible, burying her face deeper into FP's shoulder. Quiet, quiet QUIET! It was so hard to subdue her voice when he'd gotten her like this—all riled up; at his mercy.

"Ngh." The prince grunted, placing his lips on her neck and sucking on the soft skin there, leaving a bright red mark on her porcelain skin. The young man took one of Fionna's hands and laid it on the front of his sweats, over his loosely contained arousal.

"Touch me." He murmured into her ear, kissing the red lobe. "I can't take it anymore. Please touch me." He pleaded, voice desperate and rough. The need in the sound sprung Fionna into immediate action, and she slipped her hand under the waistband and plunged it into his boxers. In a haze, she wrapped her palm around him slowly, then, she paused.

"Show me," she whispered. "Exactly how you want it; what you like… How to drive you crazy." Oh… When Fionna looked at him like that, it sent shivers up and down his spine. Her cool blue eyes smoldered with want, and they radiated a more vibrant cerulean with each passing second. He took her hand into his and guided it, helping her take his sanity. "Tighter. Squeeze harder." He choked out, clutching his hand over hers to give it more force.

Her small hand slid up and down his shaft, and she pumped him steadily, gripping his length tightly. Fionna couldn't describe the look on his face just then, even if she spent the next 3 years studying the dictionary. There is just no words. He looks so good like this.

"Ah…There!" He gasped, voice barely extending beyond Fionna's ears. She'd stroked an especially sensitive spot. The prince gave her hand a few bucks with his hips, straining to feel more. "Fi—!" The boy gasped, shivering. In their awkward position on the floor, FP shifted, curling into his love. My heart shouldn't pound this hard. I swear I can barely breathe. He thought as her hand ran over every inch of his aching member. After a few minutes, Flame Prince's body kicked into overdrive. At this rate, he wouldn't be able to control his flames. If they continued like this, he'd burn the house down. Reluctantly, FP stopped the movement of his girlfriend's hand, panicking.

"Fionna. I—can't hah I'm losing my grip on the magic. I didn't think it would be so... If—If we don't stop, I'll burn this place to the ground." He panted. In response, the adventuress shook her head slowly.

"N—no. I'm still so… Wound up." She whispered. Flame Prince pulled her hand away gently.

"Me too. But I can't—" He trailed off breathlessly. The girl on his lap whimpered in disappointment. FP grimaced and looked down at the hand that connected them, and Fionna's eyes followed.

"Do you want me to continue? Until you…?" He asked, nearly laughing when her face flushed a vivid red; as if she'd grasped the compromising position they were in.

"I—I—No, it's fine! It's—not really fair." She paused and let her head fall onto FP's shoulder, cheeks burning. "Plus, I really don't think I'd be able to keep quiet." She muttered bashfully.

"Don't say that." Her boyfriend groaned, pulling his hand away from her and wiping the wetness on his sweatpants. He used the other to tug her face from his shoulder to directly in front of his own. He leaned up and touched his forehead to hers, attempting to calm down. He already felt his member begin to throb from lack of contact. All he could envision was kissing her all over, and hearing her moan over and over. He could see himself touch her until her back arched and she cried his name. He couldn't stop the flow of these thoughts, so in the meantime he zipped up her pajamas, trying to remove some of the temptation.

"Fionna."

"Hmm?"

"Could you talk to me? All I can think of is… Well, it's not helping me calm down."

"Um…Okay…" Fionna breathed heavily and groped her mind for something to say. It took her a bit to regain her thoughts.

"I—talked to Cake earlier. And I… Told her everything. And actually, she didn't freak. Okay, she said she wasn't happy, but she accepted it nonetheless. We had a good talk and she- she accepts it, Flame. She apologized. I think she's finally getting the over whatever she has against you."

"Is that so?" He asked quietly.

"Yeah, I—don't think she'll be bothering you much anymore. I'm really sorry about all her behavior before… And mine."

"I already told you not to worry about it, Fi." He said, stroking the side of her face. "Come to the castle on Saturday." He uttered in a low voice that gave away the meaning of his demand. Saturday? That far? The adventuress thought dismally.

"But it's only Thursday." Fionna whined sadly.

"Well technically, it's Friday." FP amended. When Fionna gave him a displeased, completely unamused look, the prince heaved a sigh. "It's only a day, princess." He touched her puffed out cheek. She was full-on pouting now. "I just want to make sure that no one will be bothering us. I intend to have you all day, all to myself." He whispered, giving her a quick kiss. Turning to look out the window and observed the moon slowly falling toward the horizon. "I have to go." He murmured sadly.

"Don't."

"If morning comes and I'm not there, the kingdom will be thrown into a panic. I'm still in the process of sneaking out, you know."

"Just ten more minutes." She negotiated, wrapping herself around him.

"We're always gonna wanna wait just ten more minutes." He countered matter-of-factly.

"Five, then." She answered; her final offer. He pulled her flush against his body, ignoring whatever lust he still felt.

"Six." He whispered, kissing her ear. "I'll give you these six today, and I'll hold you all day tomorrow. Deal?"

"Not a chance…It's gotta be longer. In fact, make it forever." She muttered softly. And actually, it didn't sound the least bit cheesy to her. None of it did.

"Hold you forever? Seems a bit impractical." Her boyfriend teased gently.

"Not like—! Ugh I was just trying to be—! Never mind already." Fionna huffed, offering a miserably embarrassed face for Flame Prince to feast his eyes on.

"I know," he chuckled. "Forever, huh?"

"Well… For as long as you put up with me."

"Hmm. I guess I'm stuck with you."

They quietly promised this as they sat intertwined for the next eight minutes, just listening to each other's gentle breathing. Nine minutes later, she kissed him goodbye as he was halfway out the window, and in another two he'd disappeared from sight. Fionna stood at the window until the sun peeked from beyond the mountains and the clouds, feeling a bit lonely. Saturday…
