Chapter contains a bonus scene for a friend of mine who I know prefers strong men be the ones bent over~ ;)

"So.. I was thinking about how I can repay you for letting us stay here, especially after the whole.. Crown thing." Fionna said as she shut the door behind her.

Finn shrugged as he walked to his chair, not seeing what Fionna was doing, "No need. Just keep safe and clear out in the.." He stopped mid-sentence as he sat in his chair, realizing that she'd pulled off her top, leaving her chest fully exposed to him, "But I want to~"

"You.. you should stop what you're-"

"Shhh~" Fionna cut him off, turning around and sliding down her shorts. She bent over as she did, tucking her member between her thighs to draw attention to her shapely ass. If this guy was really a version of her, then she knew exactly what he'd be into.

Sure enough, Fionna could see the impressive tent forming in his pants. Grinning, she stepped out of her shorts and underwear, leaving her in nothing but her shoes as she lowered down onto her knees and began to crawl towards where Finn was sitting, hips swaying seductively the entire time.

"I-" "Need some attention after all this time doing everything alone~" Fionna said, hands moving to his thighs, slowly working their way towards his crotch.

"So big~" Fionna purred, palm grinding against his bulge as Finn groaned softly. He gripped the arms of his chair, expression frozen in confusion as Fionna took out his cock. Her jealously at his size was eclipsed by her elevating horniness almost immediately as she felt the weight of it in her hands.

Practically salivating, Fionna began to kiss along Finn's log of a cock, hands stroking wherever she wasn't touching and pussy getting wetter as she realized how difficult it was to fully close her hands around the girth of it.

"Oh yeah, its been awhile~" Fionna purred, rubbing her cheek up and down along his shaft as one hand moved to his balls, "So full~ Its got to be painful at this point. Let me take care of it~"

Finn tried to argue, but he couldn't form the words. His head was spinning and his cock seemed to have confiscated all the blood.

The sensation of Fionna's warm, wet mouth sucking on his throbbing balls overwhelmed all other senses, and he relaxed into the chair as Fionna triumphantly worked his cock.

Soon she worked her way back to his tip and wrapped her lips around it, her own head spinning a bit from the smell and taste of the massive thing.

Fionna barely even remembered that this was supposed to be a distraction for Jay to sneak out and meet up with Little Destiny; part of their deal for Jay to show them where the magic crown is in this world.

'I can have fun and be the distraction.' Fionna reassured herself as she shuddered at the feeling of Finn's cock stretching her throat, 'But I cannot tell Cake about this.' She'd never live it down, especially not with how hungrily she was gagging on what was for all intents and purposes her own cock. Just much hunkier version of it.

'Dammit Martial was right, I AM a switch.' It was obvious of course, but Fionna was usually pretty good at choking down denial. 'Guess there isn't room for it right now.' Fionna joked to herself as she felt Finn's cock starting to pulse.

Knowing full well she wouldn't be able to swallow a load this big, Fionna worked her was back to Finn's tip, stroking his shaft hard to bring him over the edge.

Finn grunted as he came, hands gripping the sides of the chair roughly as he painted Fionna's face and chest completely in his thick, white release, his stiffness not going down at all at the sight of it; perhaps even getting worse as Fionna licked her lips, "Not bad~" She giggled, "But it doesn't look like yo-OH!"

Fionna realized she realized she wasn't going to need to do anymore convincing as she was grabbed and practically thrown against the near wall, her one leg lifted up as Finn's tip pressed against her wet slit; her cock twitching excitedly as she felt her Farmworld self's monster of a cock pushing into her.

"O-oh fuck yes~" Fionna groaned, bracing herself against the wall as she felt him pushing deeper, stretching her tight pussy.

"I.. don't know if I'll be able to hold back anymore," Finn warned through shallow moans as he felt Fionna's fit body gripping around him. "Good~" Fionna purred back, fully aware that she'd only egged him on further.

'Fuck I needed this so bad~!' Fionna thought as Finn slammed hard into her, impaling her on his cock as he started to bounce her; her own cock swinging as it leaked with pleasure.

She moved one hand to grip around it, stroking hard as the other held onto Finn. Fionna tried to think of something cool and hot to say as they rutted, but only moans and the occasional swear left her lips, mixing with the sounds of wood creaking and Finn slapping hard against skin.

Soon it was difficult to think at all, the pleasure and passion so intense, running through her body like energy through a wire.

When she finished cumming, however, and felt Finn's building as he plowed into her, a coherent thought did cross her mind, albeit much too late.

'I probably can't get myself knocked up… right?'

"You're turn~" Fionna purred as she approached Farmworld Finn from behind. He was out chopping wood for fire, and rather confused by the statement.

"Surprised you can even walk." Finn responded, raising his ax for another swing, only to end up sending it flying into a nearby tree as she felt Fionna slap his ass.

"Come on, don't pretend you aren't even a little curious~" It was a long shot, but Fionna had her logic. She'd just learned that she herself was a switch, and if Simon was right and this buff guy was just a version of her, then..~

From behind him, she couldn't see the confused blush on his face, but could see the change in his stature, and took her chance.

Sure enough, Finn didn't stop her as she slid down his pants and underwear, getting harder by the second and barely remembering to lube herself up.

"Th..this had better be-" "Aw, is the big buff farm boy scared of a little fun~?" Fionna teased, barely even able to connect her hands as she hugged around him from behind; her cock pressing against his puckered hole. He shuddered at the feeling of her tip between his cheeks.

He'd had the occasional curious thought, but tended to just convince him that everyone does and they don't mean anything. But after the previous night, Fionna had him convinced he might be wrong about quite a few things. He gasped as Fionna pushed forward, stretching the tight ring of muscle with her dick.

"O-oh fuck~" Fionna groaned, squeezing his muscled form harder as his body squeezed her in turn.

Finn took in slow, deep breaths as Fionna worked deeper, thrusting gently to get him used to the feeling.

A few minutes in and Fionna could hear the moans he was trying to suppress and grinned, picking up the pace suddenly as she broke the hug to spank him again, this time on his bare ass. He yelped, unclenching his teeth and unable to lock them again before Fionna's fucking forced the moans out of him.

"There you go, let it out~" Fionna moaned, hips slapping against him as her cock sank harder and faster into her farmworld alternate.

Finn started to bend at the hips, grabbing the tree-trunk he'd been using for woodcutting, supporting himself on it as Fionna picked up the pace again, fucking the bend over blonde with random smacks to his ass with the intent of leaving her handprint.

Alas, his muscled form seemed too tough for that. Not tough enough to stop his howling as he started to cum.

"G-god so tight!" Fionna groaned, gripping Finn's hips hard as she started to cum, plastering Finn's insides with her cum. Not nearly as much as Finn had left leaking out of Fionna the night prior, but they had all day while everyone else was out looking for clues about the crown~
