My sister came to Tokyo for work with her colleague's boyfriend. Due to the inbound tourism boom, they couldn't find a hotel in the city center, so they ended up staying in my room… My sister, who was supposed to be sleeping next to me, moved to the living room where her boyfriend was sleeping. What?! They were having sex in my room?! I pretended to be asleep, but it was going on forever!! What?! How long is this going to last?! The next day I gave my sister a stern warning! When I asked her about it, she said her boyfriend is a "super-sex addict." He apologized and said he wouldn't have sex again, so he asked if she could stay another night. My sister went to work first, and her boyfriend went to the bathroom. Of all things, the super-sex addict was jerking off in my house. I yelled at him!! He sat naked on his knees apologizing, but his penis was still hard and erect, so he naturally took it in his mouth and we had sex!! That night my sister came back from a wrap-up party with the staff and was already cumming. She and her boyfriend came back with souvenirs and things got intimate again…
