Stumbling into the bathroom, I catch my stepsister, a raven-haired vixen, fingers buried deep in her pussy, her other hand squeezing her ample breasts. Her eyes widen in surprise, but I'm already rock hard. Angrily, she tries to shoo me out, but I'm not having it. I strip off my clothes, revealing my throbbing cock. She licks her lips, her resistance crumbling. I push her against the wall, her legs wrapping around me as I plunge into her tight, wet cunt, fucking her hard and deep until we both come undone.
