Seveno-sensei, who appears to be serious and upright, is actually a lecherous homeroom teacher with a preference for young men. She had been targeting her student Takahashi and, upon discovering that his parents were not home during a home visit, she seized the opportunity to enter the Takahashi residence. During a one-on-one consultation, she elicited Takahashi's adolescent sexual concerns and then forcefully engaged in a French kiss. Overlapping lips, intertwining mucous membranes, entwined tongues… The prolonged and intense kiss stirred up lust between the beautiful teacher and her student!
