Marshall Lee wasn't sure why he was at this party. It was one of Fionna and Cake's parties in the woods, which he usually enjoyed well enough, but he wasn't exactly in a festive mood. At least it was something to do. He hadn't seen Gumball in a month and he felt hollow all the time.

"Earth to Marshall Lee!"

"Hm?"

Fionna squinted at him, looking concerned. "You've been acting weird lately, man."

"I'm fine." He wasn't fine.

"Well come dance with me then! It's a party!"

Marshall Lee couldn't help a half smile. Fionna was such a mortal. Her buoyant happiness was infectious, though. Marshall Lee started to cheer up a little as they made their way to the dance floor.

"So how's Cake?"

"Pretty good. Things are getting pretty serious between her and Lord Monochromicorn."

"Oh yeah? He seems cool."

"He is. Cake made this translator for him once so I actually got to talk to him. It was fun. What about you? Go on any cool adventures lately?"

"Uhh, not really. Mostly just moping around in caves. Vampire stuff."

Fionna laughed. "If you say so."

"You look really pretty tonight," said Marshall Lee, pitching his voice a little lower than normal. She really did. Her blonde hair was practically glowing in the lamplight.

Fionna blushed, her cheeks turning an appealing shade of pink. "Oh, hush."

"Still got that thing with Flame Prince?"

Her blush got brighter. "We're taking a break."

"Well he was crazy to let you go."

Someone grabbed Marshall Lee's upper arm in a vicelike grip. "Mind if I cut in?" said Gumball icily.

Marshall Lee scowled. "Your Highness."

"Hey PG." Fionna looked nervously awkward. "I'm gonna, uh, leave you guys to sort out whatever weirdness is going on here." She disappeared into the crowd.

"Follow," bit out Gumball, dragging Marshall Lee away from the party and into the woods.

"Where are we - oomph!" Marshall Lee found himself abruptly pinned against a tree trunk.

"What the fuck was that!" demanded Gumball. "What business do you have flirting with her?!"

"We're not an item! You didn't want to be! Last time I checked, people don't get to dictate who their non-boyfriends flirt with."

"She is a child! She's, what, sixteen? You're hundreds of years old. We both are. You're way too old and jaded to be messing around with that mortal ray of fucking sunshine."

"Oh my glob. Chill. I wasn't trying to like, seduce her or something! We're friends. We flirt with each other. It's a thing we do. She knows I'm not actually trying to get with her!"

"Does she? Does she really? Honestly, you're so dumb sometimes."

"I'm not the dumb one here! You just don't like seeing me flirt with people. Because deep down, you want me all to yourself."

Part of Marshall Lee knew he shouldn't be baiting Gumball like this, but Gumball was the one who had him pinned against a tree, dammit!

Gumball's eyes went dark. "Maybe I do," he purred, crowding even closer into Marshall Lee's space. "Maybe I want to claim you for myself. Mortal girls won't want to flirt with you when they see you belong to me."

"That's some big talk, Gumwad. I don't exactly recall you being the dominant type. You always seemed much happier when I just held you down and had my way with you."

Gumball smirked. "True enough. But I'm not in the mood tonight. I'd rather make you uncontestedly mine."

Marshall Lee groaned. Gumball kissed him hard, staking his claim with his mouth. Marshall Lee let himself be ravaged. It was certainly an interesting change.

Gumball pulled back, panting. "Glob. I've missed this. Missed you."

"I've missed-" His 'you too' was swallowed up by Gumball, who dove back in like he was starving, licking and sucking at Marshall Lee's mouth.

It was entertaining seeing Gumball try to take the dominant role, but things went a little too far when he grabbed a possessive handful of Marshall Lee's ass.

"Hey now." Withing seconds, their positions were switched. Gumball was the one pinned against a tree. Marshall Lee smirked lecherously down at him. "That's enough of that. Although it is very refreshing to see you making moves and acknowledging that you do actually want me. Makes me want to reward you like you deserve." He ran his thumb along Gumball's plush lower lip.

Gumball moaned happily and dropped to his knees, fishing out Marshall Lee's cock from his jeans. Marshall Lee had a sudden moment of doubt. He wove his fingers through Gumball's hair, stopping him from putting his cock in his mouth. Gumball whimpered.

"Bonnibel." That made Gumball's gaze sharpen. "Do you really want this?"

"I really do," he said huskily.

Marshall Lee wanted to ask him to be his boyfriend right there. He really did. But that could wait for a time when his lover wasn't eagerly waiting on his knees. "Then suck me. I'm annoyed with you for taking me away from that party, so this better be some pretty fucking fantastic head."

As soon as Marshall Lee released his hair, Gumball took him eagerly into his mouth. He set about giving a very sloppy and vibration-y blowjob.

"Oh, yeah. You're such a slut," groaned Marshall Lee. "Blowing me out here in public where anyone could walk by and see. You love it. My dumb exhibitionist slut."

Gumball moaned, his eyes fluttering shut.

"So hot," murmured Marshall Lee. "You're so hot and perfect. It's like you were made for this. Made for me."

Gumball made a choked sound, and Marshall Lee knew he'd just come in his pants. Amazing.

He finished a few seconds later, cumming down Gumball's sweet pink throat. Breathing heavily, he put his cock back in his pants and slid down to the forest floor to join Gumball, who snuggled against Marshall Lee's chest.

"How was that?"

"Great," said Gumball, a little hoarsely.

"I want to ask you something."

"Ask."

"Would you go on a date with me? I, uh, I mean, I want another shot at being your boyfriend. A proper shot this time. And I think a good way to start that would be going on a real date. I just don't think I can keep being your fuck buddy or whatever because you were right, I do still have feelings for you. But only if you want to be my boyfriend, obviously. So. Uh. Date?"

"I'd like that." He opened his violet eyes to glare halfheartedly at Marshall Lee. "But I don't want to do that thing where we, like, start abstaining from sex on our dates so we can build our relationship and bla bla bla. We're too old for that. I'm putting out on the first date and that's final."

Marshall Lee chuckled. "As you wish."
