The neighbor is far from her husband and the ending for the young man.

I was packing up when I saw a couple having sex in the apartment opposite!! The buildings on the two sides are quite close to each other, the windows are wide, unobstructed, standing on one side can see the whole view on the other. Obviously, neither of us thought that anyone would see her, she was casually changing clothes, flirting with her boyfriend right by the window, so I had the opportunity to keep an eye on her more. It looks like she's a half-blood, fair-skinned, beautiful face, slender body, I've seen it all! And then I met him, he didn't seem to be angry with me and waved at me. Her name was Lauren, and she saw that I was a gentle person and wanted to ask for help. The problem is that Lauren's boyfriend still has sex with her regularly, but he always takes the initiative to do it, making Lauren's dating skills not improve. Therefore, he wanted to invite me to "practice" with him to improve his sexual skills. If she doesn't agree, she'll talk about me spying on my boyfriend. There was no other choice, I agreed. And then our relationship started from there; we always 'worked' whenever Lauren's boyfriend was away. But there was one truth I didn't know, which was that her boyfriend also knew about this...
