Seriously, do you know how to do it? I can't figure it out.
In the meantime, where in the UK are you? If that's really you in your profile pic, I would be pleased to know my wife had been with you.
You sound like you could be ideal for us. You could seduce my wife, and you could either tell me to get lost, or allow me to watch!
Where in the UK are you?
I am in exactly your situation, OP. In fact, I have emailed another bi man to explore the idea further, but have not done anything. I'm in South Wales. Are you? Would be happy to speak further.
It is my dream to know that my wife has been cheating. Sometimes I get to watch, and sometimes not. If I do, it is always from a position of subordination.
Alas, it has never happened. Perhaps one of you could make it so.
