Did you ask your wife , you have to begin somewhere. Tell her what you want , then both of you work out the details and both of you get something to drive your sex life to a new level. Start slow don't go full on gang bang right out of the box. Dress her up , maybe get her to flash you at the bar. Drive her around with her tits out , finger fuck her at the bar , feel her up on the dance floor. Take her to a mixed bar, having already talked to a few black men . Get her to dance with a few, even slow. Then tell her she looked hot in his arms. It's not magic just nature that takes over.
