I was packing up when I saw a couple having sex in the apartment across the street!!! The buildings on both sides were quite close together, the windows were wide and unobstructed, standing on one side you could see the whole scene on the other side. Obviously neither of them thought anyone would see her, she was calmly changing clothes, acting cute with her boyfriend right next to the window, so I had the opportunity to keep an eye on her more. It seemed like she was mixed race, white skin, beautiful face, slim body, I saw it all! And then I got to meet her, he didn't seem angry with me and waved at me. Her name was Lauren, she saw that I was a gentle person so she wanted to ask for help. The problem was that Lauren's boyfriend still had sex with her regularly, but he always took the initiative, causing Lauren's dating skills to not improve. So he wanted to invite me to "practice" with him to improve my sexual skills. If she didn’t agree, she would tell me about my stalking my boyfriend. With no other choice, I agreed. And that’s how our relationship started, we always “did it” whenever Lauren’s boyfriend wasn’t home. But what I didn’t know was that her boyfriend also knew about it…
