We both work at the same store and one day we were talking about our boss saying he's womanizer and cheats on his wife with many female employees at the store. My sister told he already tried it with her but she didn't give him the pleasure. I started to tease her, saying that he has a lot better to choose from, he wouldn't bother with her. My sister got upset and asked me if I wanted to bet with her, saying she would fuck him and she would bring me the prove. She two weeks maximum to bring me the prove or else she would loose the bet. Well, the two weeks passed and she didn't fuck him, what I didn't tell her was that our boss started an hypnosis therapy a month before to treat the loss of libido and impotence. I know because I've head him on the phone with his hypnotherapist and he was completely scared about his situation. Nice move, no? My sister only requested I used a mask.
