In a cramped bathroom, Nenne Ui's "helpful" washing turns into a sensual exploration of Tatsu's body. She tentatively touches his cock, her eyes widening as it grows hard in her hand. Unable to resist, she strokes it, feeling the smooth skin of his foreskin. Tatsu, equally aroused, can't help but push his hips forward, yearning for more. Their taboo desires consume them, and they give in, fucking passionately as the shower steams up around them.
