Involving my girlfriend in my stepsister's intimate encounter leads to a wild and intense session that leaves her in ecstasy

My girlfriend caught me with my stepsister, leading to a steamy encounter. My girlfriend joined in, turning it into a wild threesome. She squirmed in pleasure, climaxing multiple times.

A few days ago, my girlfriend and I were talking about my mom's visit, and while discussing the topic of her potential meeting with my stepsister, my girlfriend suggested that I involve her in the intimate encounter. I was a bit surprised, but considering that my stepsister had always been a big fan of anal sex, I decided to give it a try. So, when my stepsister came over, we went straight to the bedroom and began our wild and intense session. After a little warming up, I managed to penetrate her tight ass, which was a bit of a challenge for me. However, as soon as I managed to get into a rhythm, my stepsister began to moan loudly and soon reached an incredible orgasm, squirting all over my cock. It was a truly amazing experience for both of us and left my girlfriend completely satisfied and in ecstasy.
