Thanks for the replies.
I thought I could add some more details about our relationship.
We have been married 2 years and since the beginning I made her aware of my kinky fantasies regarding female lead marriage, submissiveness and cuckoldry. She was quite ok with it and we played with these ideas for a while.
There was the occasional moment when we actually acted for real, like when she locked a collar on me and leading me on a leash with only a transparent underwear she paraded me in front of our windows with the risk that our neighbours could see me
She is definitely the boss of our house and I rarely challenge her decisions. Once we were having an argument and completely out of the blue she said "kneel down and kiss my feet". I stood there very surprised. It was not the moment to "play", but she repeated it and I knelt in front of her and kissed her feet.... Our argument was over.
When we go out dancing Latino music, she knows she can dance with other men without any problem. She actually says "I hope there will be good-looking guys I can dance with tonight" and then she laugh at my instant erection! I couple of times she found some guys to dance with in a more sexy way. He kept her body very close to his, hands firm on her waist, the occasional hand on the ass (to which she didn't react), the two faces almost touching....while I was on chair looking at them or in the queue to buy her a take.
So far, she has never kissed anyone, but she knows she can do it.
I love to give her the freedom to do whatever she wants even if she is not really using it!
BTW, she is 26, tall, slim and beautiful. I hope it is only a matter of time before I can see her flirting and snogging someone!
Let me know if you want to hear more about us!
