I'd say you were being set up. Nylons rip and run very easily.
If you ask any domme that likes to have a feminized male around, they will tell you that the reason for the pantyhose is so the sub is in a state of constant humiliation. They all have different ideas. Most all require panties, and never any men's underwear to be worn. With today's styles, a sub gets used to them because alot of men's underwear looks almost like women's now. I have recently met a domme that has told me that if she accepts me for her personal submissive, pantyhose, panties, a training bra for outdoor wear, and my regular breastform fillable bra indoors, along with a waiste cincher will be required. I asked her when I could remove them. I specifically asked about if i had a doctor's visit, or the like. Her answer was "Don't get sick." I know she's just throwing me a mind fuck, so don't get testy. She also told me that I would be wearing a chastity belt at all times. A suggestion was made that I could earn a specific amount of time out of the belt if I didn't put a run in my nylons. What she also informed me was that she planned to have me wear crotchless panties and suspender or garter and hose in one so she can lock the belt over them. I've never heard of a domme making a sub wear things like this 24/7 for an extended period, having to shower in them and all, but it should be interesting. I wonder if any of the ladies here can tell me if I have any possibility of wearing the same pair of stockings, say for a month without putting a run in them. Mistress says if i do, we start again, and the belt stays on.
