ERINA is a gal who works as a part-time worker at a family restaurant in the city. - She is serious about her work and is a perfectionist, but her training of new part-time workers is out of line... - Originally, she had a strong sexual desire, and in the name of guidance, she was a perverted slut who repeatedly performed acts that were more than reverse sexual harassment and almost akin to rape against her subordinates. - Today as well, ERINA meets a new guy for the first time and gets horny. She attacks the man's erogenous zones, nipples, glans, and anus, in three places at the same time and makes him ejaculate!
