Wait so Cas has a huge dick but he also doesn’t need to breathe? Amazing.

They’re in the pool, the cool water the only thing keeping them from overheating under the heat of the summer sun. Originally they had been swimming but now Cas has Dean crowded up against the wall, pressed against the wet tiles as they make out.

“I ever tell you how I don’t need to breathe?” Cas says, nosing against Dean’s ear.

“No,” Dean replies, “Is that relevant?”

“If you want it to be, it is,” Cas says, one hand drifting to Dean’s hard dick.

Cas doesn’t even bother taking a deep breath before he sinks below the water, his hair flowing everywhere, reminding Dean of a mermaid.

They didn’t bother with swim trunks, so Cas gets right to work. Dean knows that water and lube aren’t friends, but he supposes that Cas has an answer for that too, because by the time Cas takes him in his mouth, things are slick and hot despite the coolness of the water around them.

It feels like it lasts forever, Dean’s floating in the water while Cas sucks his dick, unending, taking him all the way into his throat like it’s natural that his airways don’t need to work. It’s pure bliss, and soon Dean is coming, hot spurts against Cas’s tongue.

“I can’t return the favour, sorry,” Dean says when Cas resurfaces.

“That’s okay,” Cas says, pressing in to kiss him again. He tastes like Dean.

He drags Dean to the shallow end, and situates him on the steps, so that his elbows prop him up but his ass is floating in the water. Cas does his underwater lube trick again and opens Dean up. It must be some angel point of pride thing, because Cas has the biggest dick Dean has ever seen, and if he uses mojo to ease Dean open more quickly, Dean’s grateful.

It still takes so long that Dean’s hard again by the time he’s ready. Cas slides home, finally, and it’s everything Dean could want. He feels stuffed full, the slide of it heady and addictive, small waves crashing against him as Cas thrusts against him in the shallows.

They both last for a long time, fucking hard in the sunshine. The other thing Cas has is stamina, for days. Dean’s lost count of how many times he’s been fucked this week. He doesn’t have time to think about it, because eventually, he comes again, across his own stomach as Cas lifts him out of the water, trying to get a better angle. It doesn’t take much longer before Cas is coming too, filling him up.

He’s explained to Cas countless times that he doesn’t need to replenish his semen to the fullest extent when he mojo’s away his refractory period, but Cas always feigns ignorance. He suspects that Cas loves absolutely drenching Dean with his come, inside and out. Secretly, Dean likes it too.

He’s so glad he suggested a vacation.
