Married woman Eiko emits powerful pheromones while weaving an intricate, spiderweb-like trap. Her latest target is a life insurance salesman. She crouches by the roadside, deliberately exposing her underwear and baiting him with calculated seduction. When the salesman notices and approaches, Eiko gradually ensnares him, eventually bringing him completely under her control. Before he realizes it, the man is obeying her every command, surrendering his body completely until she grants him release—plunged into an extreme state of submission. Throughout this process, Eiko's cunning and allure are vividly revealed.
