Superlady (Shizuka Yoshioka) is a superheroine who keeps the peace in Augus. Normally, she worked as a reporter for Metroview, but when incidents occurred, she fights evil. One day, the evil organization Guernica plans to... turn the Superlady into sexually dominant using a lewd insect cultivated with the G virus, a biological weapon. The lewd insect enters Superlady’s pubic region, enlarges the hypothalamus, and expels a poison that stimulates the pleasure center, making her sensitivity sensitive. Then, grown lewd insect toyed Superlady with its tentacles and extra-thick penis.... To finish off, the combatants decide to return the favor by thrusting their thick dicks all over the Superlady!
