This role-play is performed by adults. Megu-san is a beautiful older sister (she has a boyfriend) who lives next door to my apartment. One day, when I was watching a porn production at home, the person next to me could hear me, so I decided to watch it with him. She was tempted and asked, ``Would you like to do the same thing as in the porn?'' At first, she was wearing a condom just like in the porn, but it included a depiction of her removing the rubber band, and even ended up having a vaginal cum shot! ? After that, we started having secret meetings over and over again and pretending to have sex while watching porn.
