Steamy incest mother and child bathing copulation

Last year, my father remarried and I started living with my mother-in-law, Hikari. Hikari has such an erotic body that I get an erection just by looking at her, and I couldn't help but peek into the bathtub out of curiosity. At that time, I was so captivated by Hikari's bewitching naked body that he found out I was looking at her and was severely scolded, but I got an erection when I saw Hikari wearing only a bath towel... From this day on, I began to follow Hikari's orders.
