I thought I was alone, stretched out on the couch in the living room, stroking my cock while watching porn on my phone. I didn’t even hear her come in at first. My heart nearly stopped when my step-sister caught me mid-stroke, my cock hard in my hand. I tried to cover myself, embarrassed, mumbling excuses… but she wasn’t angry. She was curious.

She asked me why I’d rather watch porn when the real thing was standing right in front of me. Her eyes locked onto my cock, and before I could answer, she stepped closer and told me to touch her instead. I ran my hands over her body, feeling her curves, her skin already warm and needy. She guided my hands, showing me exactly what she liked, teasing me until I was completely out of control.

That’s when she pulled out a butt plug and told me she loved it dirty. She slowly taught me how to use it, pushing it into her ass while she moaned, spreading herself for me and begging for more. She didn’t want it gentle — she wanted it hard. She wanted me to fuck her ass rough and deep, just the way she loved it.

We couldn’t stay in one place. We fucked all over the house — the couch, the walls, every surface she could bend over. She wrapped her lips around my cock, taking it deep down her throat, knowing exactly how much it turned me on.

By the end, I couldn’t hold back anymore. I pulled out and covered her face in cum, watching it drip while she smiled, completely satisfied.
