My hobby as an unpopular guy is to masturbate to the moans of the woman the handsome guy next door brings home, which I can hear through the thin wall of my room. One day, the handsome guy's girlfriend suddenly shows up at his apartment, and the woman they were having sex with gets kicked out and runs over the balcony to my room! I get a full erection seeing her practically naked! In the midst of this, I hear more moans coming from next door...
