Rei Kuroshima is an energetic music college student who only knows the world of music. She experiences a life she did not choose and things she has never experienced before... her first work! (1) First time having sex with a teacher in school (2) First time having sex with a teacher in school (3) First time having sex while working part-time (4) First time having sex with a restraint toy (5) First time having 3P. I cum a lot in this unknown world. A beautiful woman who is too elegant forgets her class and happily has sex. Goodbye my musical life.
