Im searching for a Hypnotized/Mind Control Story I read some Time ago. It was about a Guy who brought a device to his school/college lecture with wich he could control the other students and his teachers minds, the device was allegedly from his Dads work and is top secret. It started with him ordering the girl next to him to masturbate and the other people, who were further in front, to not being able to realize it. Then it went on to him fucking his teacher and controlling the other students to fuck each other. In the second part of the story he was still fucking with to of the girls, who were also sisters.
