A drinking party with co-workers at a junior female colleague's house. Even though everyone has gone home, a man who seems like a playboy helps clean up with ulterior motives. He thinks he's succeeded in wooing the naive junior, but in fact she's a slut whose hobby is to bully aggressive men!? His nipples are attacked with a vibrator, and even his big dick screams in agony. Under the pleasure, the sadistic man who cums is just a masochistic man.
