Megu-san is a beautiful older sister (she has a boyfriend) who lives next door to my apartment. - One day, when I was watching an AV 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 AV?'' At first, she wore a condom just like in the AV, 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 AV.
