[Yamamoto Naoki] Saishin sakuhin-shū Vol. 3: 3. Yon-ka-me kara mui-ka-me | New Series Vol. 3: Five O'Clock, Ep. 3: The Fourth to the Sixth Day

An anxious schoolgirl finds herself alone with a lecherous, bald old man who dominates her body with relentless fingers and oral advances, turning a quiet bedroom into a battlefield of desire and submission. The stark contrast between her youthful uniform and his aged, naked form heightens the tension, while the repeated, invasive touches push the limits of consent and pleasure. This explicit manga volume weaves a dark, erotic narrative of power imbalance and carnal surrender across a series of intimate panels.
