My attractive stepsister discovers me pleasuring myself and requests my assistance in performing sexual acts on her

I've always been smitten by my stunning stepsister, and it seems she's taken notice of me as well. She's got a killer physique, thanks to her dedication to fitness, and a luscious, juicy ass that's just begging for attention. One day, she caught me in the act, pleasuring myself while watching some steamy girl-on-girl action on my screen. She was clearly intrigued and decided to join in on the fun. She's already got a boyfriend, but she's down for some kinky cuckold action. She's a dancer, so she showed off her moves, teasing me with her sexy dance. Then, she dropped to her knees and took my throbbing member in her mouth. After that, we moved to the couch and she let me explore her tight, wet pussy. I was more than happy to oblige her request to help her perfect her skills in the bedroom.
