Last year, my father remarried, and I started living with my stepmother, Hikari. Hikari was incredibly erotic—her appearance alone was so sexy it instantly turned me on. One day, I couldn't resist peeking at her in the bathroom and was completely mesmerized by her body. I got caught and scolded harshly, but seeing her wrapped in just a bath towel made me so aroused that I couldn't hide my erection. From that moment on, I became completely submissive to Hikari's every demand.
