Fucking Step Dad on Step Brother’s Bed

I decided that my step-daughter, Bess, and I needed to have a talk about how risky our behavior was the other day. I’m not sure why Bess isn’t in her bedroom, but I found her in her step-brother’s bedroom instead. She tells me how her bed is too small to fuck me in; This bed is a Queen size and her step-brother isn’t going to be home for hours! She starts to give me a blowjob and I instantly get hard because of her big tits. Then she lies down on the bed and she spreads her legs for me. I start to fuck her pussy in the missionary position first, and then I fuck her pussy in the doggystyle position after. I cum deep inside of my step-daughter’s pussy and it feels so warm and tight inside! Unexpectedly, my wife, Melanie, walks into the room while my cock is still inside of our step-daughter! Luckily, Melanie doesn’t get mad at either one of us… Instead, she asks to join us for a step family threesome this evening. I better take a power nap and re-charge!
