In a world where rain is sacred, two sisters, Mittsuri and Sukebe, find their desires awakened by the very thing that's meant to cleanse them. As the rain pours, they huddle together, their bodies yearning for something more than just warmth. Mittsuri's hands, clad in mittens, trace Sukebe's form, feeling the curves hidden beneath her wet clothing. Sukebe gasps, her eyes meeting Mittsuri's, and in that moment, their inhibitions wash away like the rainwater. They explore each other's bodies, their fingers tracing lines of pleasure, their breaths syncing as they give in to their taboo desires.
