To deepen the bond between women, understanding and trust are essential. Two women, both hurt by past romantic experiences with men and suffering from mistrust toward men, embark on a two-day, one-night hot spring trip that becomes the catalyst for a new relationship. Guided by a navigator from a lesbian-focused website, an amateur woman named Miyu—wounded by past love yet newly curious about women—sets off on this journey. Upon arriving at the inn, they cleanse their bodies together in an outdoor bath, slowly confirming their feelings for each other. Surrounded by warmth, their bodies grow restless, and as they begin touching one another, arousal builds intensely. Back in their room, they stimulate each other's heated bodies, reaching climax repeatedly. In return for the pleasure received, Miyu turns the tables, pleasuring the navigator's body and pushing her to multiple successive orgasms amid escalating ecstasy. The next morning, even as her body is teased and stimulated, Miyu becomes overwhelmed with sensation, crying out, "I'm gonna go!"—urinating herself in the throes of passion, her heart now irrevocably changed.
