Tiffy, my skinny stepsister, teasing my hard and stiff member

I always wanted to fuck my stepsister Tiffy, a skinny little girl with small tits and a cute face. She's always teasing me, making it hard not to touch her. Today, I decided to put a bet on it. If I could make love to her, I would get her for free. So, we started fighting, but my mind was on one thing only - fucking my stepsister. I was already hard and stiff, but I managed to control myself. After a while, she took off her clothes and I couldn't believe my eyes. She's so fucking hot! I couldn't resist anymore and I pushed her against the wall. The feeling of her soft skin against mine made me lose control and I started to fuck her. It was the best fuck ever and I hope it will become a regular thing.
