No but dean trying to hold back his moans and keeping totally quiet during sex with cas-- and one day when he nearly bites through his lip from the strain and cas finally asks him whats wrong and cas just being so exasperated at deans obvious /humanity/ because this fucking righteous man is getting fucked by an angel of the lord and is concerned about something so pedestrian?? Its absurd. Cas resolves to fucking dean long, hard, and slow until he finally just melts under him.
Mmmm Cas fucks those sweet little sounds right out of Dean. And Dean comes to love the single-mindedness with which Cas works him over, just to have some delicious vocal proof of how much Dean is enjoying himself and to have Dean be and sound how he truly wants to in bed, only furthering his joy and ridding him of his shame and his compulsion to not sound how a good boy simply sounds if he’s fucked well and good. After all, it‘s hard to manage to stay quiet if you have a force of nature pound your ass.
