Ariel Demure, my new stepsister, is a beautiful enigma. Her body is a perfect blend of soft, feminine curves and hard, masculine lines. When I find her naked, I seize the chance to get to know her better, starting with a massage. As I work my way down, I notice her big, hard cock between her legs. I pause, then decide to include it in my massage. I stroke her length, feeling her throb in my hands. She moans, her body writhing as I explore her trans form, my hands slipping over her big, firm tits and round ass.
