Introducing my stepmom's new partner to my stepsister and exploring threesome fantasies

I was nervous meeting my stepmom\'s new boyfriend, but things took an unexpected turn when we all ended up in the shower. His big black cock was a sight to behold, and my stepmom\'s big ass was just as tantalizing. We all explored each other\'s bodies, leading to a steamy threesome with my stepmom and her new boyfriend.
