A female teacher is given an aphrodisiac by a naughty student at school. While working without knowing it, something strange happens to her body! She secretly masturbates with her fingers while worrying about the people around her! However, that wasn't enough... She even used the "vacuum cleaner," "handrail," "corner of the shelf," etc. as a masturbation tool for the "male student" who was there! The teacher completely lost his senses, and when he saw a dick, he changed into a super-transformation, wanting to insert it!
