Fics like Size Matters

"Okay, so Dean fucking loves Sam's cock. But sometimes... Sometimes Sam's cock plays second fiddle. Thick and long, right on the cusp of too big to fit in a woman, and Dean's not impressed. Most of the time, he fucking moans like a whore for his brother, takes it like a champ and comes straight from the feel of it slamming inside him. But then there's times like this."
