Next time you're at a bar together, surprise your guy with a body shot of his favorite liquor. When it arrives, place the shot between your breasts (a supportive bra is a must!) and instruct him to get it out with his mouth without using his hands. Or try taking it up a notch on your patio at home by pouring drinks into each other's belly button, between your breasts or the crease in your lower back. If that doesn't lead to hot summer sex, then your steamy clean-up shower will.
