The few times Cas is angry would be Dean's fav kinda sex cuz Cas would be grunting and growling and just overstimulating the fuck out of Dean.
Oh good lord.
🌟 Angel Cas will fuck him for literally hours! He makes sure Dean never gets too dry or too tender, but he has the stamina and power to just keep moving, in and out and in and out. Whenever this happens, there is a 95% chance of Dean crying from over stimulation. He tells Dean that he’s not finished with him yet. Dean loves every second of it.
🌟 Cas makes the most ridiculous noises. He pins Dean down to the bed with a hand at the small or his back and fucks into him, grunting with the force of it. If Dean moves in a way that Cas doesn’t want him to, Cas will growl at him, tell him stay put, to do as he’s told for once in his life. If Dean starts talking back, Cas will snarl at him to shut his fucking mouth.
🌟 Cas usually has a fist buried in Dean’s hair, needing some ounce of control in his life. Dean is more than happy to give this up to him, to surrender to Castiel fully, even if he’s not the one Cas is mad at. Cas needs a physical release, exertion of anger, and he is so blessed that Dean offers himself up.
🌟 Sometimes Cas will fuck him through orgasm after orgasm, ringing him dry. Sometimes Cas edges him, thrusting and grinding and rubbing for ever, until he lets himself come, and then Dean gets to come too. Sometimes, if he’s in a particularly foul mood, if something’s really plaguing him, Dean doesn’t get to come at all. He can wait for round two.
Cas is a filthy beast in the sack when he’s cross and Dean is lucky enough to bear the brunt of it.
