AN: Not sure about the quality on this one, but I finished it. This one's a bit more mature, methinks, so I'll bump it up a rating letter, mayhaps. Also, for those curious, Prince Gumball IS in Ooo, and how that happened will be the subject of another story. Thanks for reading, and please continue.

Chapter 5

"…Finn! Finn!" Finn groaned and cracked an eye groggily. His eyes positively flew open, however, when he noticed what was on him.

"H-hey, M-m-Marceline…" he stuttered to the girl who was currently straddling him, face inches from his.

"Hey, Finn." Marceline replied with baited breath, anxious to see how Finn would react to her little sneak attack. He was silent for a long time, thinking.

"You kissed me, didn't you, Marcie?"

"Yes, Finn."

"And I don't think that was just another game just to make me blush?"

"No, Finn."

"So you like me, don't you?"

"…yes, Finn." He smiled.

"Good." in a flash, almost too fast for Marceline to see, Finn had her off of him and pinned to the floor of the treehouse. Marceline feigned a struggle before giving in, staring up at his burning blue eyes as they bored into hers. "Do you know how crazy you were driving me today, in that?" His eyes flicked down her form for a moment, lingering a bit at points. Marceline grinned up at him impishly, enjoying this turn of events immensely.

"Why, whatever do you mean, Finn?" she asked innocently, channeling her inner southern belle. Finn growled,

"You know what I mean." this new roughness to his voice sent shivers down her spine. She decided she like Dominant Finn.

"What are you gonna do about it?" She asked, leading him a bit. Finn smirked as an idea sparked in his mind: payback for all the years of teasing. Starting at her left wrist, he began planting soft kisses up and down her arm, across her collarbone, up and down her other arm and back. Then he went from her collarbone up her throat, adding a bit of light biting here and there, eliciting a gasp every so often amongst the sighs. Then, he kissed both of her cheeks, her forehead, her nose, her jawline. When he finally seemed ready to kiss her lips, he stopped with them still an inch apart. He stayed there, waiting, drawing out the seconds, as she began to struggle against him, mewling softly. He moved him lips back every time she attempted to join her mouth to his, waiting until she could hardly stand it. She writhed in his grip, and he decided she'd suffered enough and let go. As soon as she was free she reversed his pin and punced, kissing him with even more fervor than previously. This time, however, he wasn't caught off guard. He clutched her to him and bunched his fingers in her hair, their two bodies melting into one, kissing her back with strength equal to hers.

This time, his phone didn't ring.

Marceline's first notion that it was morning was the slight rays of yellow sunlight filtering in through the windows, giving her skin slight sizzle. She groaned and pulled the covers over her head.

"Finn."

"Mmph?" came the grunted reply from next to her.

"Finn, cover the window."

"Mmpphhh… sleepy…"

"Finn, cover the window!" She said grumpily, booting the wiry young man from the bed. He stood, rubbing his sore rear end.

"Fine, fine… raggum fraggum,…" he grumbled, grabbing a large blanket from the floor and loped it over the curtain hooks, plunging the world into semi-darkness. "There, happy?" He said, feigning irritation.

"You have no idea," she replied, stretching like a jungle cat and slinking out of bed.

"You hungry? I've actually got food, now." Finn asked as his stomach grumbled. Marceline noticed that she, too, was famished.

"Ravenous." she said, pecking his cheek before floating downstairs to the kitchen. Finn pulled the book Jake had gotten him the day before, "100 Dishes for the Newly Independent," and scrambled some eggs while pouring Marceline a glass of tomato juice. Together, thy ate in companionable silence, just enjoying each other's presence, until a knock on the door broke them from their musing.

"I'll get it." Finn got up and opened the door, revealing their morning visitor to be none other than Jake the Dog.

"Hey, bro, you ready for another day filled with ADVENTURE?" He cried, waving his arms about like noodles.

"Yeah man, for sure. C'mon in." Jake followed Finn inside, chattering away about their plans for the day, only to stop dead at the sight of Marceline sitting at the kitchen table, sipping from her mug. Jake was puzzled for a moment, then his eyes went huge when he noticed she was wearing basically the same outfit she had on the day before, minus a few articles of clothing ad wrapped in a bed sheet. He looked over at Finn, noticing for thee first time the faint smears of lipstick on the shirtless boy's neck and face, before turning back to Marceline.

"Sup?" she said simply. Jake chuckled weakly before scooping her up and whirling into another room, leaving behind a very confused Finn.

"Jake, what the hey-hey?" Marceline asked angrily.

"What is going on?" Jake rode over her question completely. "What happened after I left last night?" Marceline was bemused.

"I followed your advice and made a move. And good LORD, was it worth it. Do you have any idea how well that boy can kiss?" Jake looked uncomfortable.

"Uh, no, and I don't want an idea. But did you guys…" He waved his hands about in several gestures, "you know?" Marceline was confused,

"Did we what?" Her eyes grew wide as comprehension dawned on her. "oh. OH! Oh, no. No. No." She shook her head firmly. "No, we did not do… that." She looked a bit hurt. "What kind of girl do you think I am?" Jake eyed her.

"Sometimes, Marceline, I have no idea." The hurt was now painfully evident. "Look, Marcie, I'm sorry, I didn't mean it like that, I'm just a little weirded out…" she just nodding, fighting tears, and ran out of the room, grabbing her clothes. As she passed Finn, he said,

"Hey Marcie, where are you going?" She smiled through the tears and kissed him softly on the lips. He looked concerned. "What's wrong?"

"Nothing, I've just got some stuff to do. I'll see you soon, kay?" He nodded, slightly dazed, as she opened her umbrella and left. Confused, he turned to Jake.

"What was THAT all about?"

"So, uh, you and Marcie, huh?" Jake spoke up cautiously as the ambled along the path.

"I guess so." Finn smiled happily. "It surprised me too."

"Well, how'd it happen?" Finn rubbed his chin thoughtfully, feeling his sparse stubble.

"I dunno. It just kinda…did." He shrugged. "I'm happy it did, though." Jake nodded, guilty about his earlier words to her. "Anyways, what are we gonna do today?" Jake consulted his day planner.

"Oh! First, we've got a meeting with King Simon and Doctor Princess about the barbeque party. Ready to go to the Ice Kingdom?"

"Aw, YEAH!" Finn crowed, leaping onto Jake's back as the dog grew to a much larger size and galloped off. Soon enough the King's Ice Palace came into view and the duo of adventurers were ushered in by Simon's royal guard. They entered the meeting hall, where Simon and Doctor Princess were lounging and sitting primly on the royal couch, respectfully. Upon seeing Finn and Jake, Simon bounded up to them and drew them into a big bear hug.

"Finn! Jake! How have you guys been?" Finn struggled to draw breath; the wiry Russian was deceptively strong.

"We've been good, Simon. How about you?" Finn gasped out. The former Ice King released them, grinning from ear to ear.

"Fantastic, boys. I'm free, finally free! I just can't get enough, and I can't thank you enough for forgiving my transgressions as the Ice King." Finn blushed, embarrassed by the gratitude; he was a humble hero, and not comfortable with too much praise. Simon recognized his embarrassment and sobered somewhat, though still just as effervescent.

"So what did you guys need?" Jake pulled out his notepad and peered at the words scrawled upon't.

"Alright, well first off, we're here to invite you to Princess Bubblegum's Baby Shower Barbeque Jamboree. Would you like to come?" Simon grinned even wider, if possible, and scratched his short-cropped beard.

"I'd love to. But let's check with the missus; what do you think, hon?" he called back to Doctor Princess.

"Sounds great, dear." she deadpanned. Simon turned back and chuckled.

"So that's a yes. What else do you need?" Jake peered back at his list.

"Okay, so the barbeque is also a potluck, so we were wondering if you could contribute some ice sculptures and frozen treats. Thoughts?" Simon grinned, concentrated, and pulled into existence a fist sized sphere of ice, filled with twists and whorls. He looked up, eyes twinkling.

"I think I can do that."

AN: So yeah, Simon's back! That will also be a story I'm writing. Also, sorry for the bit more sexual scene at the beginning :x
