My father got married suddenly 3 months ago. I couldn't hide my confusion at living with his new wife, Ai, who is close to my age. At that time, I found out that my father and Ai's efforts to get pregnant were not going well. I was thinking that if I could change, I would like to have sex with Ai... When Ai suddenly came into my room and started stroking my dick! It seems that Ai, who had been frustrated with her sexual frustration, decided to use my dick to try to get pregnant instead of my useless father...
