Summary: based on spnkink_meme prompt: Sam leaves for Stanford, Dean is left pregnant. He's tried going it alone, but after seven or eight months, he's too damn horny and goes out to California to let Sam know what problem he needs fixed.
Dean muttered to himself darkly as he drove the impala as fast as he can. He needed to get to California and he needed to get there now! He was sick and tired of taking care of Sam’s responsibilities and now he is going to make Sam take care of it.
“We’ll be there soon,” he murmured to his swollen belly rubbing his hand over it.
Sam had gotten him pregnant. The night before he left, he had fucked Dean bareback. He had said that it would be the best goodbye gift Dean could give him. Now Dean was pregnant. Sam didn’t know; Dean had made sure of that. However, it was time he did. Dean was sick and tired of masturbating. He wanted a good hard fuck.
“Fuck me!” Dean yelled knocking the door on the floor of Sam’s apartment.
“Jesus!” Sam jumped. Sam’s eyes widened as he saw Dean. He couldn’t stop staring at Dean’s belly. His eyes were bulging out of the sockets and his mouth was hanging open.
“Oh, yeah. I’m pregnant,” Dean shrugged. “Now fuck me!”
“What the hell, Dean? You’re pregnant? And you didn’t tell me? You must be really far along, you are really big,” Sam’s eyes got even bigger. “Is it mine?” he asked in a tiny voice.
“No shit it’s yours,” Dean glared. “Can we please get to the important part?”
“But how did you even get pregnant?” Sam asked in shock.
“Sammy, I know you had the bird and the bees talk. Hell, I gave it to you. Now. Fuck. Me.” Dean said through gritted teeth.
Sam kept staring at Dean, not moving or talking and definitely not fucking Dean. Dean let out a groan of desperation. “Listen, the dildos aren’t cutting it. I need the real thing. You are the fucking father of this baby and you are going to take responsibility for it, do you understand?”
“Of course I’ll raise the baby with you!” Sam said. “I’ll be with you for all,” he looked at Dean’s belly again, “well the rest of the way.”
“Are you that dense? I don’t give a shit about that. Your cock, my ass, get on it!” Dean yelled.
“Dean, we really should talk about this,” Sam said slowly.
“Oh for fuck’s sake!” Dean exclaimed. He waddled over to Sam and pushed him backwards on to the couch. He then climbed on top of him, wiggling his ass directly over his crotch. “Fuck. Me”
“Okay,” Sam groaned. He could feel himself hardening at the contact. “Okay, yeah.”
Dean let out a shout of glee and quickly threw off his shirts. Sam couldn’t help but stare at Dean’s new body. His normally firm pecs were swollen and engorged. His thin, lean waist had ballooned out to accommodate the child growing inside of him. Sam ran his hand down the smooth belly. He let it trace the pushed out naval, then he let the dark line lead his hand down to Dean’s crotch. “God, Dean, you look so gorgeous,” he whispered in awe.
“Sammy, I like that you think I’m hot and all, but he have certain matters to take care of,” Dean said while rubbing himself against Sam’s rapidly hardening erection again.
Sam nodded and managed to yank off his own shirt. It was a struggle with Dean’s now found weight keeping him down. Dean hauled himself up just high enough to zip and unbutton Sam’s pants. He slapped Sam’s hands away when they went to feel his torso. “We can do that later! Now get to the good part!” he said in annoyance as he yanked his own pants off.
“At least let me finger you open,” Sam whined reaching behind Dean. Dean stopped him and looked at him with a satisfied grin.
“Don’t need to,” he said smugly as he pulled a large black butt plug out of him.
“At least get some lube!” Sam said as Dean positioned himself over Sam’s cock.
“I’m slick enough! Now shut up!” Dean roared slamming himself down on Sam’s cock.
Sam groaned loudly. He grasped Dean’s hip with one hand and started rubbing his hand over his belly with the other. He almost pulled away when he could feel the movement under Dean’s skin.
After Dean had established the pace, Sam started to thrust up to match it. He pounded into Dean’s perfect little ass, hitting his prostate head on.
Sam started rubbing his hand harder on Dean’s belly. The sensation was weird, but he was beginning to enjoy it. He ran the hand up Dean’s belly to play with his nipples. He started tugging and rolling the nubs and gasped when a little bit of milk started to drool out.
“God, Dean,” Sam moaned, thrusting up harder. “Your body is incredible.”
“I know!” Dean said slamming back down.
Sam could feel himself about to peak so he quickly grabbed Dean’s cock and began to jerk him off. He always preferred for Dean to come first. There was nothing better than the feeling of Dean’s clenching muscles as he came.
Dean quickly came, spilling himself all over Sam’s chest. Sam followed soon after.
“God, Dean, that was amazing,” Sam panted.
“Yeah,” Dean said. “Up for another round?” he asked after a pause.
“I need some recovery time!” Sam responded.
Dean curled up against Sam and muttered something about whiny little bitches.
“Are we going to talk about the baby?” Sam asked.
“In the morning we will. Tonight you will be too busy,” Dean grinned.
