A president's secretary with beautiful legs who incontinences every time she walks with her lower body trembling like a fawn in panties that are directly coated with an aphrodisiac.

Higashiyama, the president of a venture company, falls in love with Miu, a secretary at a subcontracting company. But it's too late, Miu already has a husband... Higashiyama, who is never one to give up, tries to make Miu his own at all costs, and as soon as he learns that Miu's husband doesn't earn enough money, he succeeds in recruiting her to be his secretary with favorable treatment. On Miu's long-awaited first day at work, Higashiyama puts her to sleep with sleeping pills and smears her with an aphrodisiac. Miu, who did not know about this, could not bear the sudden pleasure that hit her and her legs trembled and she incontinenced. ``What is this...!? My body is going crazy...!!'' And so Higashiyama's days of aphrodisiac training began.
