Shio's husband is a company president who employs a secretary. She notices the man eyeing her body with lust and, as a playful tease, makes him serve her sexually. Things get so good that they end up having sex. However, the man makes a wrong assumption and drugs Shio, taking full advantage of her perfect body. Under the influence of the drug, Shio becomes a sex-crazed nymphomaniac, seeking out his cock in the bedroom and bathroom, entwining with him.
