Pink Onesie Butt Flap Fiasco

I'm not exactly proud of this, but my teen stepsister lets me fuck her. We both like it, but don't talk about it much. I just go into her room at night, pull down her pajama butt flap and fuck her good until we both cum. I was going in for my fix and she was waiting for me in the position when she turned around and it was my stepmom ! I'd been set up. Tia said she had to teach me a lesson & I'd have to stop fucking my stepsister and start fucking her. How could I argue!? She was already wet when I stuffed my hard cock in her. She rode me like a pro and then sucked her pussy juice off my hard cock . I fucked her hard and made her cum while she talked to dirty to me and then she let cum inside her mouth. My stepmom swallowed the whole load!
