I want you to fuck your wife. yes do it, penetrate her but ... you don't have to come. you will make excuses, the important thing is that you hold back the orgasm for me.
think of me when you copulate, she will imagine that your member gets hard for her but in truth you are thinking of me. this is our little secret, and you don't want her to find out, do you?
It could turn your world upside down, and you don't want that to happen....
well, then fuck her, deny yourself and pay me.
