I'm a third-year university student. I've been dating my girlfriend since high school. After graduating, I'm in the mood to get married. But honestly, I don't feel like having sex with her. Anyway, I'm bored during summer vacation. I'll just masturbate for now. I wonder if there's something good to jerk off to... From the day I met her eyes... a dangerous secret rendezvous began... A gangster couple moved into the house opposite. Every day, they have sex by the window, showing off. ...Oh, how naughty. Me too...
