Warnings: Where to begin... dub-connish at points, marathon!sex, blowjobs, fingering, incest like woah, object insertion, multiple orgasm, orgasm denial, spanking, over-stimulation, dirty talk, knotted dildo, talk of figging, talk of infantilism, references to Dean being a bit of a sub. Artistic license taken with Dean's ability to continually get it up. Very toppy Sam. I think that's everything.
Summary: As part of the final prank war before Sam left for college, Dean slipped him some viagra while interviewing witnesses. Things didn't quite go the way he planned. (Filthy porn which turns into schmoop part way through *shrug*)

It seemed like a good idea at the time.
True that was Dean's explanation for many things, but really - it had seemed like a great idea at the time. He and Sam were in the middle of another prank war, and he'd decided to slip a couple of Viagra pills into Sam's coffee, right before they left to interview a witness.
It had backfired rather spectacularly though.
“Oh fuck, oh, ah, ah... Sam!” Dean was trying not to moan, but that was hard - difficult! Difficult, go with that - to achieve when he had three fingers up his ass, massaging his prostate, while Sam suckled on his cock.
Sam had been fingering him for half an hour now, gently sucking him for just a little longer, and he was going out of his mind. He felt overstimulated and about to vibrate out of his skin, and was just about ready to start begging.
Then Sam withdrew his fingers and Dean whined.
“Nononononono, Sam, please, more! Need more, need you-”
“Shhhh, it's okay,” Sam whispered as he stroked his hand down Dean's side. “Gonna give you everything you need.”
“Please,” Dean whimpered, not even trying any more. He was past ready to come.
“I know. Just let me...”
“FUCK!” Dean shouted as he felt Sam's mouth envelop him again, taking him much further than before and sucking hard. Within seconds he was coming hard, groaning as he fell back, feeling boneless. It took a few seconds for him to come back to himself and start to feel uncomfortable with Sam still lightly sucking at him, preventing his cock from growing soft.
“Sam, enough,” he tried to wriggle away, but Sam's weight on his leg prevented it. “Dude, seriously. Enough.”
Sam just shook his head a little, without dislodging the cock in his mouth. Dean's stomach tightened at the dark, hungry look in Sam's eyes. After a couple of minutes, Sam slid his fingers back into his brother, stretching him wide and brushing along his prostate. Dean's hips bucked up, then ground back to try and get away from the overstimulation.
“No, Sam, enough,” Dean tried to push his head away, and after one final, hard suck Sam let himself be pushed back. He didn't stop moving his fingers though, and Dean couldn't help shifting his hips.
“I don't think so Dean,” Sam shook his head, smirking down at him. “You slipped me a little something, didn't you? Well, now it's time for me to return the favour.” With that, he removed his fingers and swiftly rolled Dean over onto his stomach, pulling him up onto his knees.
“Woah! Sammy, wait-”
He didn't. What happened next wasn't exactly what he'd been expecting though. Instead, something ridged and bumpy slid into him, the lube practically dripping from him easing the way. Sam shoved what felt like the whole thing into him, then held still.
“What the fuck, Sam!?” Dean exclaimed, turning his head to stare at his brother. Sam just smiled back at him.
“I'm not going to fuck you until you beg me for it,” he informed Dean. “So until then, you can have a toy.” He pulled it out a little, then slid it back in slowly. Dean's eyelids fluttered as he felt every ridge, every bump, every inconsistency pull at his hole before Sam stilled again. “Gonna take my time with you, y'know. Since you thought it'd be funny to get me all hot and bothered in front of a witness, I'll make sure you can't sit right for days.
Letting out a frustrated noise, Dean wiggled his ass, not above using physical manipulation. Sam let out a pleased rumble, though, and simply patted Dean's ass.
“Oh yes, I didn't mention. You want it? You have to work for it.” He pushed Dean forward with a hand between his shoulders, then pulled him back. Dean quickly got the hint, and started moving himself, riding whatever the fuck was being held in his ass.
Within minutes he was shoving himself back and forth, moving hard and fast, gasping and sweating with effort. Sam was mumbling something, hand slapping Dean's ass now and then, but Dean didn't care. All he cared about was the toy inside him, rubbing against him in so many different ways, taking him closer and closer to another orgasm.
With each shove, his cock swung up to hit his stomach, and his balls would swing back into Sam's waiting palm. He needed just a little more, something to rut against properly, but he couldn't bear to stop long enough to get a hand on himself. Dean changed his angle a little, trying to get low enough to rub against the bed, then gasped as Sam grabbed his balls and tugged.
“Ah ah ah,” Sam tutted. He even took his hand off the toy so that it just sat there, slowly sliding out even as Dean clenched down to keep it inside. “You're being naughty. Get back up and maybe I'll help you out.”
Whimpering as he followed the orders, Dean held still in position on all fours, hips far away from the bed, and waited for Sam's permission to start moving again. Sam hummed, then Dean felt the toy drop out of him as there came a painful slap to his ass.
“Ow! Sam, what the fuck-”
“Don't make me gag you, Dean,” Sam warned, before delivering another hard smack to the other cheek. “You've been a very bad boy. Take your punishment like you deserve.”
Dean couldn't hold in the moan at that, and shoved himself back to meet Sam's thrusts. He loved it when his partners took control, but it so rarely happened. Sam was giving him everything he really needed, and Dean smiled as he bit into his pillow. His brother thought this was a punishment? Really?
He rained down smacks with varying levels of strength, alternating cheeks until Dean felt as though his ass was on fire. Every now and then Sam would smack directly over his hole, which felt so much better than it had any right to, and Dean had to bite his lip to keep from begging for more.
It felt like it had been going on for hours, and Dean's cock was still hard. In fact, the spanking had done nothing to deflate his eagerness. Instead he found himself getting closer and closer to orgasm again, and whined with the effort of keeping still.
Then Sam wrapped a hand around him, giving just one quick tug as he landed another slap between Dean's ass cheeks, and Dean couldn't help himself. He came with a shout, hips jerking as Sam held his dick and shoved two fingers back in his ass.
His arms trembled with the effort of staying upright after his second orgasm, and Sam finally seemed to take pity on him. He pushed Dean's upper body down so that it was resting on the bed, his hips still in the air, then held the tip of the toy against Dean's hole.
“Okay Dean, you took that so well. You can have the toy back.”
“Sam, I can't-”
“Yes you can. You will. Because trust me on this, Dean - you do not want to disappoint me. And I say you still have the energy to ride your toy.”
Dean let out a pathetic-sounding whine, but slid his hips back to take the toy into his ass again. He was so sensitive now to the variations in the surface, and couldn't decide which was worse - going slow and dragging the process out, or going fast and having the toy rubbing against his prostate.
Thankfully Sam seemed content to let him set his own pace, and Dean settled into a rhythm that felt nice. He was still panting, eyes closed, when he felt Sam shifting behind him. The toy mostly stayed still though, so he paid it no mind and just kept moving.
He was broken out of his reverie though by something nudging his lips. Dean opened his eyes to see that Sam had gotten out a bottle of Gatorade and was offering it to him. He glanced back, mind not quite catching up, and Sam smiled.
“I don't want to hurt you, Dean. Drink up. You need to rehydrate.” It was the tenderness in his eyes that broke Dean, and he opened his mouth to suck at the drink.
It was the oddest feeling, drinking like that as he rocked back and forth, and Dean had a brief flash back to when they'd been kids. Dean had often been the one to bottle-feed Sam, and it felt like a strange sort of role-reversal now.
Once he'd finished his drink, Dean felt a lot better. He felt as though he had more energy, and maybe he could actually finish this. Moving faster began to feel even better, and soon he was back to his earlier pace, moaning in happiness as he felt his cock start to harden again.
Sam was stroking his back now, a steady stream of filthy talk falling from his lips as he encouraged Dean. What really got him going, though, was how much Sam seemed to be getting off on them being brothers.
“Yeah, that's it. My big brother on his knees, getting fucked by a toy. Look so hot, sucking that drink. Maybe I'll try that next time, put you in a diaper and give you a proper bottle. Think you'd like that? Big brother becoming a baby? I'd give you everything you need, promise, I'd be a good Daddy for you. Take care of you, fuck you nice and gentle, maybe get a rocking chair, let you nurse from my cock. Fuck, you'd be so hot like that.”
Dean wasn't sure if he agreed, but the enthusiasm Sam felt for the idea was enough that he was nodding his head, willing to try it if that's what Sam wanted.
It was then that Dean realised how truly fucked he was - this had all started as a joke, but it was so much more than that. He wanted to give Sam a reason to stay with him, to not leave, or to take him along, and if that meant letting Sam fuck him whenever and however he wanted, then Dean would do it gladly. Sam meant more to him than anyone in the world.
Dean loved Sam more than anyone in the world.
“Love you, big brother,” Sam whispered, and Dean howled as he shoved himself back hard on the toy. This time, though, Sam pushed it forward as well and more of the toy pressed in. It felt like a tennis ball, shoved past his rim and sitting there, pressing against his prostate and filling him up. He groaned and spasmed as Sam reached down and quickly stroked him, coming with a hoarse shout.
Dean lay there under Sam, panting, clenching around the toy and way past caring about a silly thing like dignity. Sam was stroking his hair, his back, everywhere, nuzzling little kisses into his skin and murmuring endearments. The whole time Dean pulled himself back together, Sam was right there.
“Sammy?”
“Yeah, Dean?”
“...Please fuck me.”
Dean felt as Sam smiled into his shoulder and nodded, but didn't comply straight away. Sam rutted his dick against Dean's back for a few minutes, arms around Dean's chest, before he pulled away.
Hearing the snick of the lube cap, Dean smiled into the pillow. True he was stretched beyond anything he'd felt before, but Sam was still going to take care of him.
Then he felt Sam tapping his finger against the toy that was firmly wedged inside him, and Dean groaned at the stimulation. His hips twitched a little, though he wasn't entirely sure whether it was to encourage Sam or to get away from him.
“One day we'll have to try that,” Sam muttered, grabbing the base of the toy and slowly starting to twist it, making it easier to slide out. “I'll leave this in you and give you a good spanking one day. Not today though. Today I can't hold out any more.”
Dean let out a sigh of relief as he helped push the toy out. He watched Sam drop it over the side of the bed, and hummed in relief as he felt Sam's dick nudging against his loose hole.
Sam slid into Dean properly, in one movement. Both men groaned at the feeling, and Dean wiggled a little in contentment. Sam rocked his hips gently, pulling small noises from Dean on every inward thrust. Dean was so stretched and sloppy with lube that the pain he expected was completely absent, there was just pressure and pleasure as Sam's dick rubbed against his prostate. It felt huge inside him, but better than he'd imagined.
“Sam, fuck, that feels...”
“Yeah,” Sam panted against the back of his neck. “Feel so good around me.”
He punctuated his final statement with a sharp thrust into Dean, who shivered and couldn't help clenching around the hard length inside him. Sam set up a hard rhythm, driving into Dean with enough force to continually push him up the bed before yanking him back down by his hips. After a few minutes of trying to keep up Dean gave up and let Sam move him like a rag doll.
To his surprise, Dean realised that he was getting hard again. He'd never come so many times in one day, and had no idea how he was able to get it up for a fourth time. But Sam felt so good inside him that he couldn't complain.
Sam leaned down so that he was covering Dean like a blanket, and pressed kisses into Dean's broad shoulders even as his hips kept moving. Dean turned his head and looked up at Sam, and decided that he liked the view.
“Sammy,” he whispered, voice hoarse from his moans and shouts.
“What do you need, Dean? I'll give you anything.”
“Kiss me,” Dean asked.
The words were barely out of his throat when Sam pulled away from him. Dean didn't have time to complain though, as Sam was quickly manhandling him over onto his back before hefting up his legs and sliding back into position. This time, they could stare into each others' eyes, and Sam leaned down to claim Dean's mouth in a rough kiss.
Being bent in half like this ached, but Dean didn't care. He was being fucked into his own wet spot, but he didn't care. He wrapped his arms around Sam's neck and refused to let go, holding on for dear life. Sam didn't seem particularly bothered by this, instead he kept up his hard pace of before while simultaneously fucking Dean's mouth with his tongue.
It felt better than anything else Dean had experienced, and he wrapped his legs around Sam's waist to keep him from going anywhere. Somehow it had changed from fucking to loving, and Dean was perfectly happy with this.
After would could have been an eternity, Sam pulled back long enough to gasp out his brother's name, before his hips stuttered, and Dean knew that Sam was coming inside of him. Dean's cock had been rubbing against Sam's stomach, getting him closer as well, and so Dean ground down against Sam's hips and bucked up against his stomach, coming for the last time.
He smiled hazily up at Sam, who smiled back, before finally letting exhaustion overtake him. Dean fell asleep with Sam's dick inside him, Sam's come leaking out of him, Sam wrapped around him.
There was nowhere Dean would rather be.
