Is it normal to have this fantasy/fetish?
I occasionally fantasize about a beautiful blonde mistress wearing black leather and boots. She wraps a dog collar around my neck and keeps me naked in her dungeon. One day she defecates into my bowl and forces me to eat it, saying that if I refuse to eat then I will die of starvation. While I am eating she takes out my cell phone and tells me to smile while her feces is smeared over my teeth, mouth, and lips. She takes a photo. She then instructs me to remove my penis and testicles with a dull knife and warns me that if I refuse then she will have no choice but to send that photo she just took to all my family and friends. I feel conflicted but I don't want to be utterly humiliated and embarrassed so I comply with her wish. After I have successfully castrated myself, she erupts into laughter and informs me that she has already sent the pic to everyone anyway.
