I surprise my stepsister in the shower and have sex with her from behind.

I stumbled upon my stepsister in the shower, her big ass and tits exposed. I couldn't resist, and we engaged in a steamy encounter, her ass taking my throbbing cock in a wild, hardcore session.

I was taking a shower when my stepsister walked in. At first, I was surprised to see her, but then I couldn't resist the urge to fuck her. She's always been hot and I've had a crush on her for a long time. I knew I had to take advantage of this opportunity and I didn't waste any time. I took her from the front and then from behind, fucking her hard and deep. She moaned in pleasure as I pounded her, her big ass bouncing with each thrust. I could tell she enjoyed it, and I certainly did too. After a while, I came all over her back, marking my territory. It was a steamy encounter, one that I won't forget anytime soon.
