A mixed-gender hot spring hidden deep in the mountains of a certain prefecture. From midday, married women gather here, creating a scene that's become a local tradition of this secret onsen. At this bath, numerous women soak nude without covering their bodies, chatting freely. Rumor has it these married women are willing to sleep with male guests. Hearing this, we went undercover with hidden cameras. Upon arrival, we found many housewives had already gathered. Among them were women who provocatively displayed their bodies to male guests. When approached, one woman casually conversed while posing as if exposing her breasts. She remained unfazed even as her body was touched, openly allowing her pussy to be rubbed and a man's cock to be stroked. As the crowd thinned and we were left alone, our intimacy naturally deepened.
