It is such a delight especially sliding into her silky smooth pussy after he has cum in her.
I think that sharing your wife is an absolute pleasure and mine loves it. Not into humiliation as it is for her pleasure not mine although I do get pleasure out of all the arranging and her enjoyment. Often thought about the psychology behind this and wonder whether it emanates from a shared love thing as I come from a large family. My other thought has been that it reinforces how much she loves me as sex is just sex, whereas we have love and making love.
