We were at a convention in Palm Springs and stayed over a few days after it ended. The hotel had several swimming pools but my wife had forgotten her bathing suit. She found some small bottoms that fit in the hotel gift shop but none of the tops worked, or were too ridiculously expensive. However, she had packed a thin stretchable camisole dance-wear-type top to sleep in that matched the bathing suit bottoms well enough and seemed acceptable to wear to the pool even though it was cut extremely low.
We found a spot by the steps at one corner of the pool close to some businessmen there for another convention and started relaxing. When she finally got hot enough from laying in the sun she dove into the water. As she came up the steps out of the pool my heart skipped a beat; not only was the thin material clinging tightly to her, but the weight of the water had pulled the top way down so her breasts were nearly completely exposed. I know some of the guys had the same unobstructed view as I did since she paused on the steps to adjust her bottoms.
She knew I enjoyed this and didn't adjust the top right away,pretending to not realize what had happened. This pattern went on all afternoon; sometimes she wouldn't even adust her top at all, and would lay on her back as if nothing was amiss. Her nipples were nearly totally uncovered as these gentlemen looked on just a few feet away.
A little later she even sat by the steps on the edge of the pool and we started chatting with a group of other men who had arrived nearby, all the while one or both breasts clearly visible to them as she leaned in to converse. We both enjoyed all the attention she was getting.
When the day finally ended we gathered our belongings. By this time the camisole was so stretched out it couldn't even come close to covering her up so when she bent way over to put on her sandals she "accidently" fell completely out right in front of us. She recovered gracefully. What an amazing thrill. She was still pretty uncovered as we walked back to the room and more got to see her as we went. We saw three businessmen who had just checked in waiting for an elevator and she subtly pulled the top down a little more as we approached the door. They easily saw her nipples peeking above the top as we rode up.
