My wife's sister came to stay at our house. I hadn't had sex recently, so I was feeling like it was getting hard to masturbate, but then my sister-in-law suddenly started playing with my nipples. "Hey, do men's nipples feel good too?" she asked, flicking my nipples, which are actually quite sensitive, and as she licked and sucked them, my erection reached its peak. Even though my wife was there, I couldn't hold back any longer, so my sister-in-law and I started playing with each other's nipples, and it just wouldn't stop!
