Last year, my father remarried and I started living with my stepmother, Hikari. Hikari has such an erotic body that I get an erection just by looking at her, so I couldn't help but peek into the bathroom. At that time, I was so fascinated by her voluptuous naked body that I got caught peeking and was severely scolded, but I got an erection when I saw Hikari in just a bath towel... From that day on, I started to do whatever Hikari told me to do.
