Proč to dělá?

Today I found a strange letter in the mailbox. It was nothing except a USB stick. I was interested in what is on it as well. But what I saw shocked me totally. Some pervert has secretly installed cameras in my room and filmed me in how I masturbate. A really scary feeling to know that you have been unnoticed observed. Who knows how long this bastard is watching me. I'm sure that was not all. But I have a suspicion who did that. I will avenge me you pervert.
