I surprise my young stepsister in her bedroom and have sex with her, finishing on her face

I stumbled upon my stepsister in her bedroom, and the sight of her luscious curves was too much to resist. Despite knowing it was wrong, I couldn't help myself. I approached her, my desire overwhelming me. I started by fondling her ample breasts, feeling the weight of them in my hands. Then, I turned her around and plunged my throbbing member into her tight backdoor. She moaned in pleasure as I violated her, my hands roaming over her voluptuous body. The sight of her big ass bouncing as I fucked her drove me wild. Finally, I released my pent-up desire, coating her face with my hot seed. It was a taboo act, but one I knew she secretly craved. And now, we share this secret, our forbidden tryst adding an extra layer of excitement to our relationship.
