It's a pity there isn't more listed in this forum. The idea of having to ask a Dom /Bull to have any for of physical contact with my wife is an immense turn on for me.
Wife and i are very much into Femdom. She dominates me often and we've frequently spoken of involving another in my humiliation / training.
I have a penchant for female feet and my wife knows this. I can only imagine the exquisite humiliation of being made to ask a Dom male / Bull, perhaps having to phone hum or text Him for permission to kiss my own wife's (Mistress') feet then having to phone or text back and thank Him for the privilege. I think my wife would find such a scenario to her liking (not to mention funny to Her amusement) too.
