He closed the door carefully behind him before he turned the tap on, then spent at least ten minutes getting the water to just the right temperature, but he didn't care. This was going to be worth it. When the water was perfectly warm, Dean filled the ice bucket a little more than halfway, grinning as he reached out to turn the tap off. He cradled it close to him as he eased back into the bedroom, but Sam hadn't moved an inch from where he'd passed out two hours ago. Which just made what was about to happen all the more delicious. And deserved. "Teach him to booby trap my baby," he muttered, scowling at the memory of the Vaseline that had been smeared all over his steering wheel yesterday afternoon. And on the inside of his windshield. And on the gear shift. And - Okay, fine. So he was a creative little shit. And maybe Dean had ditched him to take Brittani Steroso to the movies, but c'mon! She was hot! And easy! Or at least she would've been, he was sure of that, if Sam hadn't acted like a jealous bitch by tracking him down and whining until Dean took him home. He'd lost out on a fine piece of ass, but that didn't excuse what Sam had done to his girl. He should've just told Dad. It would serve Sam right, because if Dad ever found out what he'd done, Dean knew he'd have him detailing the car once a week for the next year, along with doing an extra round of PT every day, putting in some overtime hours on the shooting range and - Yeah. Call him a soft touch, but he just couldn't do that to the kid. It didn't mean that Sam wasn't going to pay, though. Dean looked down at the bucket in his hands, then over at his sleeping brother and grinned. This was going to be good. Sam had fallen asleep in his usual awkward sprawl, arms and legs everywhere, and for a moment, Dean was struck by just how tall the kid was getting to be. He'd started sprouting up last year, somewhere around his fifteenth birthday, and now he was pretty much all arms and legs. And hair. Dean reminded himself to take care of that later, preferably before Dad got back and decided to shave it all off like he had two summers ago. But first, he had a little payback to dish out. He crept over to the bed and set the bucket down, then reached for Sam's hand. "Shhh, it's just me," he said when he felt Sam tense, and sure enough, he went limp almost instantly. God, this was just too easy. Dean smirked as he guided his brother's hand into the warm water. He silently counted to ten, and just as he reached the end, he heard Sam let out a soft groan and saw him shudder as he let go. Bingo! Dean choked back a laugh, but when Sam didn't immediately bolt upright and scream about kicking his ass, he found himself starting to wonder if it had worked. That had sounded like Sam's thank-God-I-finally-got-to-a-bathroom groan, but what if the water wasn't warm enough? Without really thinking about it, Dean slid his hand under the covers, groping blindly until he managed to wedge it under his brother's stomach and - Yeah. Oh, yeah, that had definitely worked. Because that warmth under his fingers was - huh. Really warm. And he could feel - shit, he could actually feel Sam's dick flex against his hand as he pissed. Dean swallowed hard and shifted a little closer to the bed, hand slipping down a little to cup him completely. And Sam just kept pissing, a sleek warm flow that soaked through his shorts and into Dean's hand, unlike anything else he'd ever felt. Holy shit. Another low groan from his brother made Dean's attention snap up to his face, but Sam looked completely unaware of anything except the simple pleasure of his bladder emptying while he slept. His lips were half-open, his features relaxed, and he was probably the most beautiful thing Dean had ever seen. Dean deliberately didn't think about the fact that he was thinking that about his brother, or that the kid was only sixteen, for fuck's sake; all he cared about was that Sammy was gorgeous. He leaned up to brush a kiss against his lips, and it wasn't until he sat back that he realized that he was hard. Not just kind of hard, either. Really hard. Like, insanely, blindingly, holy- fuck-I'm-gonna-scream-if-I-don't-come-in-the-next-five-seconds hard. Sam's dick twitched against his hand and let out a final spurt that made Dean have to shove his free hand down to grab the base of his own dick through his shorts so he didn't cream himself right there. Right. Okay, first things first. Get his hand back, then get into the bathroom so he could get off before Sam woke up. Then forget the whole thing had ever happened. He drew in a shaky breath and started to ease his hand back when suddenly there were dark, hungry eyes staring at him. Dean barely had a second to register that Sam was awake, holy shit, Sammy was awake and Dean had his hand against his dick, when his brother whispered, "Don't stop," and his orgasm hit him in a blinding rush of white that left him shivering and shaking as he soaked his underwear like he was thirteen all over again. When he could see again, he realized that Sam was watching him. And more than that, he was grinding down against his hand, hips moving in small circles as he sought friction. Dean licked his lips as he felt Sam's dick fill, hardening right there in his hand. "Move over," he said roughly, suddenly hungry for the touch of Sam's skin, Sam's body against his, Sam's dick in his fist, and okay, he was really going to hell for this, but he was going to make sure the trip was worth it. In the end, it was worth everything. Even getting up early and walking the two miles to the laundromat to do the laundry.
