Cheating on my stepdaughter with her boyfriend while he's out

I've been eyeing my stepdaughter's boyfriend for a while now. Every time he comes over, I can't help but ogle at his thick, meaty cock. And when her back was turned, I finally gave in to my desires and took him deep into my mouth. I loved every second of it, especially the way he filled me up. After a steamy session of deepthroating, I let him fuck me from behind, pounding my tight pussy like a pro. Then, I climbed on top and rode him like a wild cowgirl, making sure to show off my fat, juicy ass. The sight of my big, bouncing ass drove him wild, and he kept pounding me harder and faster. But the fun didn't stop there. I bent over and got my ass pounded some more, leaving me completely satisfied and craving more.
