My stepmom is so hot you wouldn't believe it. She just moved in with us, and my dick was hard all the time. I couldn't stop thinking about filling her wet pussy. The problem was that my stepsister also wanted to fuck her. That's why we made a bet: whoever fucks her first wins. We tried and tried all week. We each got naked in front of her, we tried touching her, we proved we could give her an orgasm, but nothing was working. That's when we realized what was missing. If we really wanted her, we had to join forces. Turns out sharing is even more fun than competing.
