A female classmate who found out that I, a virgin, had a masturbator came to my house and said, ``Show me how you use it!'' ``But I can't use it unless it's erect, so you'll become a wanker...'' I said to him jokingly, and it turned out to be a miracle that even though I was on the phone, I turned into a wanker! I got carried away and even started touching her if she was a wanker... Then, the girls also became horny, and the atmosphere became naughty! From the masturbation demonstration to the state where you can insert it into a real hole!
