I stayed at a certain hot spring inn. While soaking in the inn's pride, an open-air bath, I was surprised to find it was mixed-gender, and one after another, female guests started entering. Many of the women had beautiful figures, and especially those with big tits, their cleavage accentuated, caught my eye. Unable to help staring, my heart pounded and I naturally became aroused. Noticing my reaction, the women grew interested and began approaching me without caring who saw, both in the bath and in the rooms. It was as if their hidden desires had begun to stir.
