I've always been into the kinky stuff, and my girlfriend knows it. She's into it too, which is great. One day, she decided to bring her friend over, and things got wild. Her friend, a hot MILF, was dressed in the sexiest lingerie. She's not my mother in law, but she's still way older than me. The two girls started to tease me, and before I knew it, they were both riding me. My girlfriend joined in, and we had a wild threesome. The whole time, my stepmother was watching, bound and helpless. She could only watch as her daughter and her friend rode me hard. It was a crazy, taboo experience, but oh so hot.
