[SW-507] My sister's friend comes over to my house and pretends to study wle trying to seduce me with panty shots. I don't know if it's just a prank or if she's serious, but I have to teach her a lesson with my erect penis.
During summer vacation, while our parents were away, my sister's friends came over for a study session at our house. The girls, who were very interested in H, deliberately showed me their panties to enjoy my reaction. It seems that even when my sister is away, they secretly come over wanting to teach me various things about my penis. My penis immediately reacted to the overly cute and erotic panty-flashing temptation from the girls, and I secretly had sex with all of them while everyone's eyes were elsewhere.
