Erin Everheart and Olivia Madison are fucking with a shared lover

A girl at school spread a rumour about me, saying that I'm bad at sex. I asked my stepmom and stepsister for help, but it turns out my stepsister was going through the same thing. How do I know? Because I caught our stepmom teaching her how to suck a cock with the biggest cucumber I've ever seen! Based on what I can tell, I don't think she needed much help, but since I was there, my stepmom thought it would be easier to show her how to do it if she sucked my dick. My stepsister learned how to give a blowjob like a pornstar in no time. When it was my turn, my stepmom wore a strap-on dildo and pounded my stepsister, teaching me how to move to make her cum and fuck her harder. Once I saw her do it, it was my turn to try it with both of them.
