My father suddenly got married three months ago. I couldn't hide my confusion when I lived with my remarriage partner, Ai-san, who was close to me. At that time, I found out that my father and Ai-san's fertility wasn't going well. If I could change it, I would like to have sex with Ai-san, or something like that ... Ai suddenly came to the room and started to squeeze my cock! Apparently, Ai-san, who was frustrated, decided to use my cock instead of her useless father.
