Dean was already shuddering and panting. How could Sam do this to him? Make him so crazy with need? He had his hand on Sam's head, shoving Sam's face furhter into his ass as he bent over and tried to expose the sensitive flesh of his hole to Sam's mouth as much as possible. Sam was all for it, sucking and rooting as deep as possible into Dean's ass.
Dean looked at himself in the wall-length mirror, his green eyes deep and dark with desire, cheeks flushed, lips colored by the rush of blood as well. He felt his need for Sam igniting all of his veins, but at the same time, he was perplexed. He had really just come in here to go to the bathroom. He didn't expect Sam to follow him in here. He had been unzipping his pants when Sam snuck in behind him like a damn gazelle and bent him over, and started licking his asshole, which brought up other matters, he wasn't coming in here to piss.
Dean was a very clean person, and normally had no worries about Sam's mouth being on any part of his body, but he was somewhat concerned now about what would happen if he couldn't hold it, because he really had to go when he walked in here. Currently, he didn't even want to think about shitting. His dick was painfully hard from take-charge/commando Sammy, and he wanted the sexual release, but he had his doubts about how long he could hold it in.
Sam turned him around and forced him hard against the bathroom counter, the edge of the cold marble digging into his lower back. Sam held him in place while he sucked his cock, like Dean was going anywhere. Sam's mouth was hot and wet and he sucked with an urgency that was contagious. Dean was totally under his spell. He was ready to do anything, and those pretty lips and puppy dog eyes told Dean Sam wanted something, but Dean just couldn't figure out what right now. Things seemed to be working out in his favor, and then Sam did the thing where he ran his rough tongue under that spot on the underside of Dean's dick. Dean groaned uncontrollably and felt his knees buckle, and saw why Sam had him pinned to the counter. Dean was putty in Sam's hands, willing to do anything at that point for Sam to get him off, and fast damn it.
"Sam," Dean grunted, mustering the most authoritarian tone he could while his cock was being sucked to perfection, "don't tease me," Dean said. Sam kept his mouth wrapped around Dean's cock while he brought his hand out from behind his back. Dean's eyes widened.
"Oh no, Sammy. Sammy, we can't do that right now," Dean said. Sam took one more firm swipe around Dean's cock head with his expert tongue and then slowly released Dean's cock with a pop. Dean was holding himself by his forearms on the counter.
"Why not?" Sam asked, his eyes glowing in such a way that Dean could see Sam knew exactly why not. Sam squirted lube on the "Ramrod" style dildo. It reminded Dean of a fat, rubber sword. It came to a point at the tip, thickened down the shaft, and ended in a rubber gripped hilt for easy maneuvering. The sight of it usually made Dean's mouth water. Sam could fuck the hell out of him with that thing. Between Sam's spankings and the fucking with the Ramrod, Dean's need for punishment was well fulfilled. Now, the sight of the toy made his stomach hurt. Shitting all over the place in front of Sam was not his idea of a good time.
"You don't want to do this, Sam," Dean said.
"Why? Have you been a dirty boy?" Sam said and sucked Dean's balls, swirling his tongue around them in his mouth, and then releasing them to lick up the underside of Dean's cock, finishing up by using the tip of his tongue to swab out Dean's slit.
"Sam," Dean pleaded.
"I don't need to see it, Dean. It's enough for me to know that you know it's in there. I want to know how dirty you feel everytime I thrust inside you," Sam said, "I just want to fuck you with our pal the Ramrod here, and make you come for me, and then leave you alone in here to clean up," Sam said and made out with the head of Dean's cock some more. Dean couldn't think, the head of his cock was becoming overly sensitive and he had an ache building low in his stomach like a rock from needing to shit. He took a deep breath and looked down at Sam kneeling in front of him, fondling Dean's balls in his perfect fingers. Sam slid the tip of the Ramrod into Dean's ass before he could protest any further. A bit of panic rose in Dean and his chest tightened.
"Don't worry, Dean. Once its good and inside you, I'll leave it in, so I won't see anything, okay?" Sam said, but hoped like hell he would. "Now, lean over and hold on to the bathtub," Sam commanded. Dean complied, hoping his arms would hold him up. "Assume the position," Sam said with a smirk and forced Dean's legs apart with his knee. Sam's order barking sent waves of pleasure through Dean's body every bit as powerful as the bumps to his prostate he was expecting from the Ramrod.
Sam started fucking him hard with the toy, forcing the Ramrod halfway in, but halfway was enough as Dean clenched around the studded rubber shaft, paranoid that he would not be able to hold himself and that Sam would be able to see evidence of that. The little studs poked at Dean's sensitive entrance every time Sam pulled in and out, the rubber hilt like a sword meant Sam could thrust with power and precision, making Dean literally squirm as he tried to enjoy the ride, but keep from completely letting go.
"Fuck yourself on it, Dean," Sam said and held the toy still with one hand as he unzipped his jeans and freed his cock with the other.
"Sam, I don't know," Dean said. Dean was frustrated. Sam knew that he could not control himself enough to fuck himself on the Ramrod right now and worry about the possibility of an accident, and Sam was already jerking off.
"I could come just from watching you squirm with this dildo hanging out of your ass. You know what will happen if it falls out, Dean," Sam said. Dean could see from the way Sam was furiously pumping his cock already that he was not bluffing about being able to come just from seeing Dean stuck bent over with the long black dildo halfway in his ass.
"Come on, Dean, just pull your ass apart and bounce up and down a few times on it for me. Show me you can do it, and I'll get you off and leave you alone, I swear," Sam said as he worked his fist faster over the head of his cock and bit his lip. Seeing Sam so hot and bothered over him made Dean's heart thump in his chest. He gripped his ass cheeks in both hands and slowly lowered himself back on the rubber shaft as Sam held it firm for him. Dean groaned. There was pain in his stomach.
"Sammy, it hurts," Dean said as he took almost three fourths of the studded rubber up his ass.
"It looks really good Dean, just a couple more times. Show me you can take it all the way in, and I'll suck you off," Sam said as he teased the head of his own cock. Dean could tell by the way Sam was pumping his cock that he was past the point of no return, and he wanted Sam to have something good to look at when he came. Dean pushed his stretched hole down the shaft and took it in until he felt the hilt on his ass, getting a wet gurgle in response from his stomach. He wondered if he had made a mistake. He heard Sam's breath catch in his throat, so he rode up and down on the fake cock until he heard Sam groan and felt the warm splash of Sam's come on his lower back.
"Oh, fuck, Dean," Sam said, turning him around and kissing him, sucking the tip of his tongue. Sam pushed him down on the toilet with his legs spread. Dean's body knew what that meant and it was almost too much to bear, but Sam held him down tight and fucked him hard and fast with the Ramrod while he sucked Dean's cock. Dean clenched his thighs and his teeth to keep from screaming with pleasure as Sam thudded the oversized dildo against his prostate again and again, every thrust hurting and feeling like the most amazing thing ever. Sam closed his eyes and stuck his tongue out to lick Dean's balls as he deep throated Dean's cock. Sam let Dean ride his mouth through his orgasm. Dean jerked and groaned and left a pretty little puddle in Sam's mouth. Sam sucked every last bit of come out of Dean's slit.
"You always come so pretty for me," Sam said and rubbed Dean's thigh. Dean hadn't fully recovered his ability to talk, which always surprised Sam, but Sam could see staying in the bathroom with Dean any longer really would be torturous for him. Dean's ass still spasmed around the hard unforgiving rubber. Sam pressed a kiss to Dean's lips and released his grip on the Ramrod. He slipped out the bathroom door, leaving Dean to clean himself up.
