The open-air hot spring I was looking forward to was closed for repairs, so I reluctantly went into the indoor bath. To my surprise, several female customers came in! Moreover, the indoor bath was mixed-gender, and we ended up bathing together. The bold behavior of the female college students playing around in the bath made me desperately try to hold back my erection! They kept pushing closer to me, and I ended up having sex with them in a way that felt like being attacked.
