Under the guise of a shared bath, Hinata and Nozomi's innocent sisterly bond unravels, revealing a web of carnal lust. Nozomi, her eyes heavy with desire, watches Hinata's every move, her body aching for her sister's touch. Hinata, oblivious yet tantalizing, soaps her body, her hands lingering on her breasts, her ass. Nozomi can't resist any longer. She reaches out, her hands replacing Hinata's, her touch firm, possessive. Hinata gasps, her eyes meeting Nozomi's, their reflection in the mirror a testament to their shared sin.
