After getting a job in Tokyo, I moved here and started a new life. While arranging my belongings, I saw a couple having sex in the apartment across!!! The buildings were quite close to each other, the windows were wide open with no obstruction, standing on one side you could see the entire opposite side. It seemed like they didn't think anyone could see them, the girl casually changing clothes, being intimate with her boyfriend right next to the window, allowing me to observe her more closely. The girl seemed to be of mixed race, with fair skin, a beautiful face, and a slender figure, all of which I could see! And then I was discovered as well, the girl didn't seem mad at me and waved for me to come over. She was Lauren, she noticed that I was also a gentle person so she had something to ask me for help. The thing is Lauren's boyfriend always took the lead in sex, which prevented Lauren's sex skills from improving. Therefore, she wanted me to help her "practice" so that her sexual skills would be better. If I didn't agree, she would tell her boyfriend that I was peeping. With no other choice, I agreed. And our relationship started from there, we continued to "practice" whenever Lauren's boyfriend was away. But there is a truth that I didn't know, that Lauren's boyfriend also knew about this...
