(I'm suddenly in a smut mood, soooooo.
Here's some Wincestiel.)

Cas never knew he could feel this way.

He had two very handsome men filling him up, and he loved every second of it.

His legs were around Sam's waist while both of the Winchesters pounded into his hole.

Dean was behind him, holding his waist tightly as he thrusted into him and Sam held his sides as he pounded into him from the front.

Cas suddenly screamed and threw his head back, resting it on Dean's shoulder. One of them had hit his prostate very very roughly. And he loved it.

Sam and Dean looked at each other for a second, then back at Cas.

"Who did it Cas?"

"Me or Sam?"

"I-I do-don't know."

Dean thrusted up and growled when Cas didn't scream like he did the first time. He wanted to be the one who made him feel good.

Sam smirked a bit and thrusted after Dean. He started to grin when Cas screamed again.

"It-It was Sam! Right there, please!"

Taking turns, both brothers started to thrust, taking turns hitting his prostate.

Cas shut his eyes tightly and kept screaming and moaning. He was close and didn't know how much longer he would last.

Sam and Dean also felt their releases coming. Both of their thrusts started to get sloppy.

Dean suddenly growled and moaned loudly as his seed started to fill Cas. At the sound and feel of Dean coming, Cas came as well, tightening around both their cocks and moaning loudly. The feel of Cas tightening around him, made Sam cum as well.

All three of them stayed in their position, panting loudly.

Dean eventually pulled out, then Sam followed in suit. Cas dropped his legs from around Sam's waist. Sam cleaned himself up before dropping onto the bed. He felt the side of him. Peeking, he saw it was Cas, then saw Dean flop down on side of Cas.

The three of them stayed together in that bed, softly panting, not speaking, and eventually fell asleep one at a time.

~Extra~

Cas noticed both the brothers had fell asleep and smiled lightly. He softly kissed both their cheeks before curling up and falling asleep.
