My new adult stepsister is a notorious local tease who tempts me every day. When she learns I am a virgin, she finds it amusing and pushes her seduction until I finally give in and lose my virginity to her. Just as I am about to cum, she clamps her legs around me and forces me to remain inside. Whispering in my ear, she orders me not to creampie her yet and makes me keep pounding. An adult stepsibling role-play.
