Chapter Text
“C’mon, gimme another couple reps,” Dean said, his tongue heavy in his mouth. Below him, Cas was red in the face, sweaty, his brow furrowed and lips slightly parted, laying down on the gym bench. The bar between their hands was fucking loaded with weights. Couple hundred pounds. This probably wasn’t safe, but none of the gym attendants seemed to care. After 1AM, at their pay rate? Dean supposed everyone was lucky they even bothered to show up.
Cas grunted and keened, his chest heaving and threatening to burst through his too small tee. Down. Another breath. Up.
“That’s it buddy, keep it pushing,” Dean coaxed him, his voice at a whisper. His eyes flicked to where Cas’s legs shifted, his hairy, thick thighs bulging through nylon and spandex and his gut clenching and jiggling. Dean clenched his own thighs in response, squeezing his groin right above Cas’s head.
Cas gasped. Down. Up. His face was so red and he was sweating so much, but he kept his eyes trained on Dean as if their eye contact was what kept him going. Like it was all he needed.
“You got it, man,” Dean said, “Gimme a little more, give it to me, c’mon.”
Cas’s eyes rolled back in his head and down and up the weights went. Dean helped him get the bar back on the rack. Cas groaned so loud when his arms fell to his sides, Dean was glad they’d moved their workout sessions to the graveyard shift. The sound could have been recorded for porn pop-up ads. He gasped for air as Dean patted his face and chest hard, loud thumps sending a thrill through Dean’s whole body. Dean’s hands came away from Cas’s body slightly wet and smelling like Cas, though he tried not to think too much about that right now. Now, Cas needed him. Dean stepped back to rummage through his gym back to produce a cold pack and a premade shake, light pink and thick. He offered it to Cas, who sat up with a wince.
“Easy, easy,” Dean said, sitting next to Cas on the bench and placing a hand on Cas’s lower back, “You did real good, Cas.” The guy was sweating and swaying, a far-off look in eyes and a smile tugging at the corner of his lips. Cas took the proffered drink and began to guzzle it without ceremony, some of it falling out the side of his lips and down his thick neck. “Hey, I said easy. This is a special mix.”
Cas looked at Dean sheepishly out the corner of his eye before wiping his mouth with the back of his hand. He heaved another breath, his mouth hanging open, winded from eating so much so fast. Dean licked his lips when the fan blew a gust of Cas’s newly worked up musk over to him. Sweat and protein powder. Dean suppressed a grimace, despite the way the back of his neck heated and how his stomach swooped.
“Sorry, Dean,” Cas breathed out. Another whiff of his breath. Sweet and heavy. “I know you put a lot of thought into your creations.”
“Damn straight, I do,” Dean said, trying to keep his mouth closed so he couldn’t taste Cas’s smell anymore, “This one’s got turmeric in it. And I beat the church fair ladies to the farm stand on Broadway this weekend, so those are local strawberries you’re tasting.” Dean smiled, his tongue between his teeth.
“You must have gotten up very early to do that,” Cas said solemnly, “They never seem to leave much behind if you arrive after them.”
“No, they fucking don’t,” Dean said, “Bitches swipe everything for the stupid cookies and junk food they make.”
Cas hummed in agreement before taking another swig of the shake. Dean watched Cas’s Adam’s Apple bob and swallowed himself.
“Taste anything else?” Dean asked.
Cas tilted his head, a little line appearing between his brows, and ran his tongue along the inside of his mouth, stretching his cheek out far. Dean’s mouth dried up at the sight and his skin felt tight. He looked away.
“I can’t place it…” Cas said.
“‘Course you can’t,” Dean said shaking his head, “You got the palette of a five year old. I could be putting store brand grape jelly in these things and you’d think it was great.”
“… Wouldn’t it…?”
Dean scoffed and shoved Cas’s shoulder, his whole body breaking into goosebumps when his hand slid on Cas’s still sweat slick skin.
“You’re fucking gross, dude,” Dean said, “No, it’s got a different kind of protein. This one comes from buffalo milk instead of cows. Supposed to be way more protein packed. We’re gonna get you bulked up on this shit.”
“That does sound good,” Cas hummed. He turned his body to face Dean, “Thank you very much, Dean.”
Cas was still heaving from his work out, his fat chest really testing the limits of his workout clothes. Dean knew he should probably buy Cas a new set because these really didn’t fit, but part of him thought no harm, no foul. Besides, sometimes Cas got a little funny on Dean when he was spending too much money.
“Don’t mention, Cas,” Dean said, “With this in the plan, we’re gonna hit your goal before Christmas.”
Cas was too busy drinking to respond. Dean watched him guzzle and his eyes flutter shut in clear rapture over the drink. The sight of him gulping down the shake Dean made only a few hours ago so sloppily and greedily, without a care in the world sent another thrill through Dean. Dean bit his lip, his own shorts starting to feel tighter.
“Alright, I’ll see you in the office tomorrow?” Dean asked, suddenly needing to get home and hit the showers.
Cas looked at him without taking his mouth off the bottle and nodded, the last of the protein shake oozing out the side of his mouth. Dean clapped his shoulder again and darted away to the locker room to retrieve his belongings.
Once Dean was home and in the shower, he tried to plan a new recipe for Cas, moving his loofa fast and rough over his body. While thinking of what Cas would like, Dean inevitably started thinking of Cas’s full lips, covered in pink shake, the froth of it collecting in the corners of his mouth. His mind wandered further to Cas’s smile and tongue lapping at the plastic cup, asking Dean for more. Next time, Dean would get the wild strawberries from those weird forager hippies. The intensity of the flavor would make Cas moan even if he couldn’t tell what was so good about it and then he’d look at Dean with those big baby blues and Dean would tell him the difference between—
Dean cut the water off and shook his head. His dick throbbed between his legs, dripping from the shower and he looked at it quizzically. He swallowed before reaching for his towel, resolutely ignoring it. From the kitchen he could hear his toaster oven ding. His dinner was ready.
Frozen lasagna he made two weeks ago; absolutely way too much for one person, especially someone on his fitness regimen. It’d probably be better if he had someone to share it with. He’d never gotten the hang of cooking for one. His folks were always on him about finding someone to cook for, but Dean barely had the time for his job and to workout. He couldn’t imagine leaving his job now and he really couldn’t imagine cutting out his workout time with Cas. It was fine, he could keep overcooking and freezing. It was economical and ecofriendly.
