Weddings, barbeques, family reunions and vacations: summertime is all about socializing, and your calendar is pretty much booked until Labor Day. Being at someone else's home offers a risky (and incredibly sexy) opportunity to mark off some of those location-specific sex acts from your bucket list. The key here is mastering the art of a quickie (read how to here) and stifling those moans the best you can. Make it an irresistible challenge for your guy by giving him a list of places you want him to make you orgasm at the places you're going: on the kitchen sink while everyone's asleep on vacation, at the reception hall in the bathroom -- or even in the ocean while the rest of the gang is playing beach volleyball. The options are limitless.
