I’ve noticed him doing it a couple of times, his study room window faces my bedroom window, I usually notice him look into my room or walk by it number of times.
He is in his early 20s and I decided to mess with him, so today I opened my shades, before I went for a shower. I came out with nothing but a head towel and layed on the bed taking nudes.
There is a huge mirror against my bed, I knew he was looking and he could see it all on the mirror.
I hope this will make him stop spying.
