"Sexercise" is a training that combines sex and exercise. The famous coach who teaches this lesson is Micah-sensei, a busty young wife and pervert. She stimulates the penises of the participants using techniques based on her own theory, giving them orgasmic experiences they have never experienced before. The participants' sexual desire and sensitivity skyrockets, and they collide and intertwine with Micah-sensei, their adrenaline at maximum. Sweat and juices fly during the serious coaching, and a storm of orgasms erupts at the end...!
