Prompt: Bottom Bill is love, Bottom Bill is life! I request a fic with some smutty Bottom Bill! That is all.

Warnings: NSFW

Bill moaned as fingers dug into his sides, carving crescent shape indents into his flesh.

He arched up into the body above him, moaning right into the wet mouth that was currently connected to his, loving the tongue that was rubbing against the walls of his own mouth.

The hands slowly moved down his bare waist, petting his skin languidly as they went, settling on his hips right over the edge of his slacks, gripping hard enough to leave blooms of bruises.

Bill keened at the pressure. Who knew Pine Tree was like this in bed?

Not Bill, that's for sure.

Dipper grinned as he heard Bill's needy noises, feeling the body under his shiver in delight at his touch.

Nipping the demon's lower lip, Dipper slowly drew back, watching the trail of saliva break as he moved down lower, brushing his lips against the demon's neck, causing another shudder and hiss to come out. The brunet scraped his teeth against the heated skin located there while simultaneously scratching at the blond's hips.

"P~iine Tr-ree…" Bill moaned out, voice breathless.

Chuckling, Dipper wasted no time digging his teeth into Bill's neck, drawing out blood before lapping it up with his tongue, rolling his hips over Bill's to send the demon below him wild.

"Nn~ghh…" Bill gasped right into his ear. The arms around Dipper's neck tightened as the demon tried to pull the boy closer, trying to buck up and get more friction against the brunet's hips.

Dipper pulled away a little.

"Not so fast." He purred into Bill's ear, giving the lobe a small nibble. "You're so needy."

Suddenly, Dipper broke Bill's hold on him, leaning back and centering his weight onto Bill's crotch, rolling his hips again.

"F~uck, Pine Tr~ee!" Bill snarled, bucking up again.

Dipper chuckled darkly again, staring down at Bill with half-lidded eyes, eyes gleaming with lust.

"Not so fast, Bill." Dipper purred.

Bill snarled. "I swear if you don't-"

Before Bill could even start his demand, Dipper reached down to pinch and rub his nipples, causing the demon to let out a loud keen.

"I don't think your in any position to demand anything, Bill."

The demon growled.

Dipper smirked and slowly licked his lips with his tongue, making sure Bill's eyes followed the movement.

The demon squirmed underneath him again, grinding up against him and causing the brunet's eyes to roll back with pleasure.

"Beg." Dipper gasped suddenly.

"Wh-What?"

Dipper leaned forward slightly, putting more pressure on Bill's needy cock. "Beg for me to fuck you. Beg for my cock. Show me what a slut you are."

Snarling again, Bill dug his fingernails into the sheets, glaring up at the boy on top of him. "Fuck me, Dipper Pines. Right into the mattress. Make me your-"

Dipper thrust his hips down, making sure his erection rubbed right up against Bill's.

"Make me your bitch!" Bill howled out, flinging his head back on how Dipper feltso fucking amazing…

Dipper's hands went straight to Bill's belt, yanking it off and tossing it to the floor before lifting himself off the demon some to yank both Bill's slacks and underwear down, letting his cock spring free.

Dipper's smirk grew at the sight of the pearly pre-cum already oozing out of his slit, the liquid glowing in the silver moonlight.

Dipper bent his head down, making sure Bill was making eye contact with him.

"You really are a slut, aren't you?" The brunet laughed, making sure his breath billowed over Bill's member, causing the organ to twitch.

Bill made another small keen, the noise completely needy.

Not breaking eye contact, Dipper lightly licked the pre-cum off the tip of Bill's cock, teasing the slit a little as he did so.

Once again, Bill dug his fingers into the mattress as he moaned again.

"D~iipper." Bill called out, making the brunet twitch a little himself at the sound of Bill calling for his real name. "F~uuck me already~!" The demon keened.

Unable to turn down an order such as that, Dipper grabbed the waistband of his own boxers, shucking the offending article of clothing off and tossing it behind him.

Reaching over Bill, Dipper held back a moan as his own member rubbed against Bill's ever so slightly as he grabbed the lube on his bedside table. Gripping the bottle tightly in his hands, the boy squirted a good amount onto his fingers, making sure they were perfectly slick before dropping the bottle on the bed and forcing Bill's hips upwards to reach the demon's puckered hole.

Dipper slipped a single finger into the opening, loving the feeling of tightness that closed around his digit.

Bill, meanwhile, moaned at the intrusion, bucking his hips again at the pleasure of finally being filled with something. Pine Tree worked his finger in even more, stretching him out a bit more before adding another one of his amazing, talented fingers. Hissing through clinched teeth, Bill threw his head from side to side as the fingers in him started to scissor, preparing him all the more.

"P~iiine Treee~" Bill moaned again. "Please."

Pine Tree- curse him- removed his finger slowly.

"F…fuck me already!" Bill cried out.

The sound of a lid snapping open and close made Bill wriggle his hips in anticipation, trying to egg Dipper on to move faster.

"God, you're impatient." Dipper complained as he slicked himself up, leaning upwards again to press himself against Bill. He lined his cock up against Bill's entrance.

Then, Dipper jerked his hips forwards, fully pressing in a sheathing himself into Bill.

Bill screamed at the sudden intrusion, and moans spilled forth from his mouth as Pine Tree backed out again before thrusting right back in, slowly working his way into a rhythm.

"G-god. F~uck, D~ipper!" Bill moaned as he wrapped both his legs and arms around the other, pressing in even closer and bucking his own hips up to try and match Dipper's accelerating pace. Small noises emitted from Dipper himself as he pounded into the body underneath him, reaching his edge sooner than he had anticipated. Growling, he bit deeply into Bill's neck, causing another keen to come from the demon's mouth.

Bill cried out as pressure and heat built up in his neither regions, everything getting hotter and hotter. Face screwing up at the pleasure, Dipper's pace grew erratic as he slammed into the man below him, finally finding and hitting Bill's prostate in his mad need for friction, causing another scream to rip out of Bill's mouth as the demon came, white hot liquid shooting out and painting Dipper's chest.

Groaning at the sound and the feeling of cum dripping off him, Dipper gave one last thrust before cumming himself, filling Bill completely before falling still.

For a moment, neither demon nor man moved and the only sound in the hot room was their matching pants.

Then, very slowly, Dipper pulled out, collapsing right next to the demon.

The two laid there, side by side, saying nothing and just listening to each other's breaths as the exhaustion caught up.

Sighing in content, Dipper turned over to Bill, pressing in close to the demon and wrapping his arms around him, nuzzling his chest softly.

"Heh. We really need to clean up." Dipper muttered, his eyes already falling close.

"That we do." Bill murmured back, turning on his side to press his face into Dipper's sweaty head, his own conscious swimming.

The two said nothing more as they drifted off to sleep.

This is really the first smut I've ever written for these two, so some feedback would be much appreciated!

By the by, if any of you guys want to steal an AU idea from here and make a story off it, feel free to do so! All I ask is to make sure you credit me and the person who made the prompt (which is just someone on tumblr, usually an anon.) That is all.
