A midsummer public pool turns out to be an unexpected hidden spot, remaining nearly empty. The visitors aren't here to play but are focused on sports and training, creating a completely different atmosphere. Due to the small and narrow facility, the number of users is limited, mostly consisting of men and women who come to work out rather than relax. Security is lax, and the changing showers have a relaxed vibe, often leading men and women to accidentally enter each other's sections. In these enclosed spaces, young swimmers in swim briefs and school swimsuits encounter one another—guys getting hard, girls getting excited. Experience quick, intense sex scenes featuring athletic amateurs in the private shower room.
