My younger brother's friend who came to visit us was a regular customer at a sex shop where she secretly works part-time! She told me not to tell her family about it! She allowed her to have raw sex at home, which is prohibited from happening at the store!

One day, my younger brother brought a friend to my house. While greeting me, I took a glimpse and found myself a regular customer at a sex shop where I secretly work part-time! Seriously, it's dangerous!! While we were alone together, I told her not to tell my family that she was part-time, but she asked for a service that was prohibited from being a regular customer at the store, and even though I have a younger brother, it was no use just giving a blowjob in the hallway...
