Supernatural Smut [REQUESTS CLOSED]

Finally [Extra] X Sam Winchester (Smut)

Loud moaning rang from upstairs.

"Dean?" Cas said, turning. "What is that noise?"

"That, Cas, is (Y/N) and my brother making up."

"She sounds like she's hurt. Maybe we should help." Cas started for the stairs.

"No! Cas, she's fine. Trust me. She's better than fine."

"Whatever you say, Dean."

"I always knew she liked him more than me..." Dean muttered under his breath.

"I'm going to check on them." He ran in front of Cas.

"If you take another step toward that bedroom, I'm gonna have to tie you up."

"SAM!" Your voice screamed.

"God, why am I cursed?" Dean muttered before he put on headphones.

But didn't close his eyes.

He had to watch Cas, who was staring intensely at the stairs.

If only Cas understood, Dean chuckled. If only.
