Sophomore of college. Was in a quad. Girlfriend of quadmate moved in with him unofficially. They would fuck like every day very loudly and very violently; there was a mirror right outside the room, but before they would fuck, they would violently flirt in front of the mirror. He would embrace her as he rubbed up against her and call her names like "dirty little whore" and a "fucking filthy little skank," and would spank her really hard, before they would go in the room and fuck. They were aware that I could hear them through the walls and made fun of me for not getting anything. My roommate joined in the mockery.
I look back and laugh; they had a pretty dysfunctional relationship and at least I wasn't the roommate. Jesus Christ. I regret I didn't punch him in the face, but he could beat the shit out of me. Assholes.
