Abe Mikako Mikako's first hypnosis brainwashing project! A junior is called to the house of an annoying senior and ordered to tutor his female student sister for free. Since he can't resist his senior, he sets his sights on his beloved sister and gradually brainwashes her using the hypnosis he learned at university...! He turns his sister into a sensitive bitch who orgasms from her nipples, throats, and brains, turning her into a masturbator! The sister, dominated by the junior's dick, is transformed into a submissive pussy that begs for creampies! [Supervised by Shibuya Event Club]
