Full Prompt
While trapped in a cave Sam and Dean are hit with some sort of sexpollen. Sam fucks Dean hard. Crowley and Castiel are trapped with them and have no other choice but to watch (as if they would look away; Crowley is really amused and Castiel is really curious).
Summary The only thing that could make a cave-in worse would be this.
