Wife Thought She Was In A Private Pool Shower Until Guy Walked In

We went to stay at this cheap hotel for a couple days. It was on the beach with an indoor heated pool. After sitting on the beach awhile my wife and I head to the pool and she wants to go wash all the sand off.

She finds the shower over to the side all the way in the back. There's no door, and for some strange reason according to her she thought it was private. So she pulls her bikini bottoms down to her knees and is washing all the sand away when she turns around and a random guy is standing there just watching her.

According to her they both pause for a minute, she pulls up her bikini bottoms and leaves with the guy smirking. The crazy thing is my wife was clearly turned on by this and so was I.
