I received a message from my cousin Momo, who had just moved to Tokyo, saying she missed the last train at a drinking party and needed a place to stay. It was already late at night. Although I was thrilled to see how cute my cousin had become after so long, it was too late, so I went to bed as is. When I woke up in the morning, Momo was on the bed with exposed nipples and panty flash, looking incredibly erotic. I didn't know where to look but when I tried to wake her up, she still had that unguarded atmosphere. As I wondered what to do, Momo herself suggested sex! Wait, is Momo really that kind of person? Her slutty appearance was so different from my memories that I was confused, but I ended up having sex with the flow… and we kept going all day long… A documentary film suddenly appeared showing a cousin who turned into a slut and had sex.
