My neighbor's boyfriend went back to his hometown and she couldn't control her sexual desires. She masturbated every day. As I was listening to her masturbating through the thin wall as usual, she called out to me. "Hey, you're listening, right? I won't cheat on you, so please watch me masturbate and help me." That's when I started helping her masturbate. With my fingers! With a vibrator! With my raw cock! The neighbor's sister stirs up her milky mucus! Women's masturbation is more nasty than men's!
