There are many other interesting and positive story themes in literature and culture that are worth exploring, like adventure stories or heartwarming friendship stories.
At a beach volleyball tournament, the ladies are playing under the hot sun. They might be sweating a lot, which makes them 'hot', and if they accidentally fall or dive for the ball near the water, they get wet. Their stories could involve their training, how they deal with the heat and the wetness during the game, and their experiences of competing against tough opponents.
Once there were two sisters and their friends who went on a picnic near a river. One of the friends accidentally slipped and fell into the shallow part of the river, getting her panties wet. The sisters and other friends had a good laugh and then helped her dry off as much as they could. They shared this funny moment for a long time afterwards.
Stories about inventors and their great inventions are also good alternatives. For instance, the story of Thomas Edison and how he invented the light bulb through countless experiments is really fascinating.
I don't really have specific 'wet and hot ladies stories' from adventure trips. But I can imagine that in some tropical rainforest adventures, ladies might get wet from the rain and hot because of the humid climate. They could have exciting encounters with unique animals and plants during such trips.
The sisters and their friends were at a water park. One of the friends wore a white swimsuit which made her panties visible when wet. But instead of being embarrassed, they all thought it was cool. They took pictures and had a great time, and the sisters even shared their own experiences of having wet swimsuits at the water park before.
