First time with my stepsister: Ass fucking and cumming

In our bedroom, my stepsister and I finally gave in to our desires. I took her from behind, her ass bouncing in my grip as I pounded her hard. She moaned, writhed, and climaxed, covered in my hot cum.

It was a steamy summer day when my stepsister finally decided to let loose and give in to her desires. I had been harboring a secret for a long time, one that I couldn't keep any longer. I had been fantasizing about her tight, round ass, and the thought of fucking it had been driving me wild. As soon as she caught me staring, she playfully kicked off her boots, revealing her luscious, inviting ass. I couldn't resist any longer, and I reached out to touch it, my fingers exploring every crevice, every curve. She moaned softly, her body quivering with pleasure. I pushed my cock into her tight hole, and she gasped at the sensation. I thrust harder, my movements becoming more intense as I felt her tightness give way to my size. I fucked her hard, my big cock stretching her to the limit, until I finally came all over her ass. It was a sight to behold, a testament to our forbidden love.
