[※Poison Hand = A secret technique passed down in the Yanai family to make a woman yours] Office worker Yanai is a master of the 'Poison Hand' that can make any woman his slave. He visits the company of the assertive and arrogant female president, Mary, for business. Although he is overwhelmed, he somehow manages to shake hands with Mary using the 'aphrodisiac poison hand'. Mary resists at first, but gradually becomes unable to resist the pleasure brought by the poison hand -- she soon becomes aroused and falls into a sex addiction... Once you have her, she's yours. The No. 1 S-class female president goes wild with pleasure, shaking her large, sensitive breasts.
