But you should look at the girl and realize that another way to give her sensual pleasure has not yet been invented. Of course, it's up to everyone. But I made a choice for me. And the cheerful smile of my partner tells me that I was not wrong in my choice of caresses.
If your wife gave in the ass, her sex life will now be enriched not only with you. Feeling herself at least once a bitch - a woman will want more adventures. By the way, a lot of husbands want this very thing from his wife. Definitely will not be bored!
