Dennis was propped up on Robby's sturdy hardwood desk with the man's thick fingers pressing against his cervix, when he realized he needed to go. Jack sat beside him, holding his leg open. Occasionally he reached over and smacked Dennis on the clit, careful not to impede Robby's efforts.
Robby knew exactly how to use his fingers. He'd press them in as possible, rubbing in scissoring in all the ways that made Dennis' eyes roll back and his thighs shake. It was way too easy to get lost in the sensations of being finger fucked by him, and that's exactly what led to Dennis' current predicament.
"Daddy," He panted. "I need—I need to go."
Glancing from Dennis, to Jack, and then back, Robby used his thumb to toy with the boy's clit. Dennis whined.
"What do you think, Jack?"
He slid his free hand onto Dennis' stomach. Ignoring the way Dennis shook his head no, he pressed down on his bladder.
"I think he should hold it like a good boy." Jack said.
"No, please."
"It'd be pretty pathetic if he pissed himself, don't you think?"
"Can we really expect any better of our boy?"
They talked as if he wasn't even there. Jack laid another swat against his clit, making Dennis tense. He was bearing down on Robby's fingers hard, so scared of failing his daddies and being a bad boy.
"I think you should fuck him. It's not often you get to feel him that tight." Jack suggested.
Dennis sagged against the desk as Robby pulled his fingers out. He hated feeling empty, but it was much easier to hold it when those long fingers weren't pressing against his bladder from the inside.
"Condom?" He mumbled, waiting for Robby to prepare himself. Jack and Robby laughed, but he wasn't sure why.
Robby pulled his hips to the edge of the desk, and Jack re-positioned himself to lay next to Dennis. It was hard for Dennis to focus. The pressure was overriding his thoughts. One of them—he wasn't sure which— was playing with his clit, rubbing and pinching hard enough to make him moan.
"Next time," Jack spoke next his ear, nuzzling his hair. "I want to see you wet those lacy panties daddy got you last week. You would do that for me, wouldn't you, baby? I'd take you into the yard in just your panties and your collar, and order you to piss yourself like the dumb little puppy you are."
Embarrassment flooded his veins, thinking about their neighbors peeking through their blinds and watching him ruin his underwear. Tears welled up in his eyes. The press of Robby's cock into him was a welcome distraction. He was hot, thick, and it burned a bit, even after the rough fingering his pussy has already taken.
"Daddy, I don't think I can hold it. It's so gross. Please don't make me." He begged.
Jack sucked his teeth in disapproval. His hand pressed over the boy's mouth, silencing the protests. "It doesn't matter what you want, Den."
Robby's thrusts pushed Dennis up the desk, big hands wrapping around lithe thighs to pull him back. He fucked Dennis hard, aiming for the boy's bladder. Jack reached down again, pressing, pressing. Dennis frantically tried to shake his head no. His tears streamed down his face, dampening his curls. He wanted to be a good boy. He tried so hard not to let go, but daddy's cock was stretching him open so wide he just couldn't clench down tight enough anymore.
His muffled sobs rang out as the first few dribbles slid down his ass. He was so dirty, pissing himself on Robby's cock like a fucking baby. Jack pushed harder and the dribble became a gush, splashing between his and Robby's bodies. He was disgusting, but it felt so good. Robby's cock was slamming into the perfect spot, and he was cumming before he was done wetting himself. Eyes rolled back in his head, he writhed under his daddies.
"Good fucking boy. It felt that good, huh? We know exactly what you need, even if you don't." Robby said.
"You want daddy to feel good, right Den?" Jack asked. Dennis nodded. "So you'll let him come in you, won't you?"
His eyes widened, he shook his head. He didn't want to be pregnant. He knew he could make daddy feel good another way, if they'd just let him up. He could make daddy cum with his hands, or his mouth, or even his ass. He didn't want daddy to cum in his pussy.
"Oh, baby. I don't think he can help himself, it's what daddies are meant to do." Jack cooed at him, softly brushing Dennis' tears away when they began falling again.
Dennis tried to push him off, but Jack just held his wrists down. He tried to kick at Robby, but the bigger man pinned his thighs to his stomach, fucking him even deeper than before. The boy's piss dripped off of them with every thrust. It sounded so wet and disgusting. Dennis was humiliated.
"I'm close." Robby grunted, his pubic hair grinding against Dennis' sensitive clit.
"This is what you deserve, baby. Fucked full of your daddy's cum, letting us give you what you need."
A few more shallow thrusts and Robby was coming inside of him, hot and wet. The boy squirmed, trying one last time to get away, but his daddies kept him pinned down. They laid there while Robby rode out his orgasm before he pulled out, cum dripping down Dennis' cunt.
"You're gonna thank daddy, Den." Jack uncovered his mouth.
"No!" Dennis cried.
Robby landed a harsh slap against his cunt and Dennis came again from the sting. He slapped the boy's cunt again, and again, and again, until Dennis was straining to close his legs to stop the blows.
Jack gripped his jaw tight. "Tell daddy, 'Thank you for filling up my sloppy pussy.' And you better sound grateful, or I'll go get the paddle."
"T—thank you for filling up my sloppy pussy, daddy." Dennis whimpered.
"Of course, baby." Robby gently kissed him.
