I came to Tokyo with excitement and anxiety for my new life in the city. To keep the rent low, I chose a share house where men and women live together. Living in the city, and with women... to be honest, there were a lot of things I didn't understand. As expected, on the first day of moving in, I witnessed an unbelievable sight! A female resident was exposing her bare buttocks through a mysterious wall with a hole in it! ? What's more, a male resident was rubbing her buttocks, licking her vagina, and inserting his penis into her without a condom! ! What is this? What does it mean? I was confused, and the landlord told me, "In a share house, men and women get into romantic relationships and end up fighting, so this is a tool to avoid that." And when it came to using the wall, the female residents were not reluctant, but rather happy? Is this normal in this share house! ? If so, this property... is too amazing! Because I can have sex with women who are not my girlfriends as much as I want! It's like the world of erotic manga! It was confirmed that my new life would be incredibly erotic!
