I once had sex with my wife in an outdoor hot tub in Vegas in the middle of the day. When we started we were alone. My wife climbed in my lap and I playfully nibbled on her nipples through her bikini top. The next thing I knew she had pulled both breasts out of her top and I was sucking on her hard nipples. She reached down and pulled my cock out of the leg hole of my swim shorts and slid it into her pussy. We kissed as she gyrated up and down on my throbbing cock. At one point I noticed that there were 2 older gentlemen in the hot tub with us. "I don't care" my wife told me as she continued to grind. It was both exhilarating and embarrassing, but I would do it all over again if I could.
