A leading lady instructs her on the seductive lingerie she purchased for me in exchange for oral pleasure

I recently purchased some seductive lingerie for my girlfriend, and in return for her wearing it, she agreed to give me a blowjob. However, I had another plan in mind. I wanted my girlfriend to teach my girlfriend how to properly put on the lingerie, as she struggles with it herself. Once we were both ready, my girlfriend took charge, instructing her on every detail of the lingerie. After that, it was time for me to take over and show her how to properly pleasure me with her mouth. But I didn't want just one girl, I wanted two! So, I called over a few more hot girls to join in on the fun. We all took turns fucking my girlfriend, each of us taking turns to bang her in various positions, including doggy style and from behind. It was a wild gangbang with big boobs, big ass, and big cocks, leaving everyone satisfied at the end.
