Hibiki Ootsuki - オーガズムのループで

Hibiki Ootsuki is a race queen who has an exclusive contract with a certain company. One day, due to poor race results, the sponsors leave and the team is on the verge of dissolution. As a last resort, she is given an aphrodisiac by a company executive to liven up the team, which has lost its motivation... Then the elegant and ladylike Hibiki changes. She seduces the men around her and, in a trance-like state as if possessed by something, she repeatedly climaxes with massive incontinence and convulsions.
