Joanne's white swimsuit! (Patreon)

On a hot summer afternoon, Joanne and a group of friends decide to have a pool party at one of their houses!

One of the guys lets loose a water balloon, splashing directly on Joanne's chest. Her white plain swimsuit turns sheer as it absorbs the water, revealing everything underneath! Everyone notices, and the guys have to sit or hunch over to conceal their erections.

"What's the matter guys? The party's just started!" Joanne noticed the change in atmosphere, oblivious to her see through swimsuit!
