A current music student at a prestigious university, 'Rin Kuroshima' (20), embarks on an experience that she never had before... Her first time being fully devoted to someone else! (1) First time having sex with her school teacher. (2) First time performing oral service play just to please him. (3) First time getting intimate with a coworker during her part-time job. (4) First time using restraints while playing with sex toys. (5) First threesome/foursome experience. In unfamiliar territory but extremely aroused by these new encounters, Rin, an exquisitely beautiful woman, forgets herself and enjoys passionate intercourse like never before. Sayonara to her life in music; hello to a world of sensual exploration!
