I've been giving C# lessons for a while now and a girl at my school asked me whether I could give her some private lessons on networking since she was creating a 2d game. I said yes and after school she paid me and we went to her home. Once there after 3mins two of her friends came over and they kind of started to "pick" on me, but more in a sexual way. So she whispered to me "So I want you to teach me everything you know but not about coding", needless to say I was horny af and started to kiss her. Her friends joined us and in about 5mins I found myself naked with 3 girls giving me a blowjob. It was the fucking paradise. However after a while when one of her friends was riding my dick, I was kissing that girl and her other friend was masturbating..her parents came home. They were simply shocked. Started to yell at us but at a certain point her mom said "why didn't you invite us" and removed her dad's belt. They joined us and we had a fucking orgy at her house.
