In the heart of feudal Japan, a strict Shinto father returns home to find his two young daughters, Yumi and Hana, lost in a taboo embrace. Their forbidden love intertwined, they share stolen kisses and caresses, their hands wandering under kimonos, exploring uncharted territories. Yet, their pious upbringing haunts them, and they struggle against their desires, torn between duty and passion. As their father's footsteps echo, they hastily separate, but not before Yumi's hand has found Hana's virgin core, leaving them both breathless and yearning for more.
