Aki Eri's sharp teeth clearly mark the man's fingers, arms, and shoulders. Her gentle licking of the bite marks feels almost affectionate, as if they are deeply in love. Yet her actions are not mere pleasure—they appear driven by a twisted, runaway affection. In stark contrast to the man's pained, contorted expression, his lower body betrays intense arousal. Eri gradually shifts her biting to his chest, abdomen, and thighs, eventually leaving her marks even on his face. Even during sex, she never stops, continuing to bite his body with semen-smeared lips. Her actions reveal a deep obsession that goes far beyond ordinary sex.
