Hametsu no Yuuwaku - Season 1

After losing her virginity to her teacher Yohito, Itsuki blackmails him into a secret affair by threatening to expose the incident. She now considers him her unofficial husband. Their relationship is characterized by a stark contrast between public and private behavior. In public, she maintains a flawless image and treats him with contempt, while in private, she shows him affection. Following school, she routinely visits his room. There, she teases him, using her feet to stimulate him before proceeding to engage in intercourse on the sofa, moving her hips provocatively. She often adopts a submissive role in private, waiting for him to take the lead. Yohito finds himself entangled in this illicit and exciting dynamic, yet he grows increasingly concerned about its consequences. The situation is further complicated by the appearance of an outside party intruding upon their arrangement.
