夏とプールとイソギンチャク ～わたし巨乳にされちゃった？～

Our heroine, Airi, is a girl with a modest bust.

One day, she discovers a suspicious creature named "Iso-kun" deep in the pool's pump room, and is intrigued by its "typical tentacles."

Unable to contain her sexual curiosity, she lifts up her swimsuit and lets it crawl over her.

It's gross, but it feels good!
