She has a sister who is a popular idol and is held a grudge against her... and is forced to imitate her. Show me a sexy pose like your idol sister! A female teacher who has been caught out by a weak point (infidelity). Teacher! Take it off! Let us see! The male students crowd around her!! They all take turns around the much-admired teacher "Emily"!! A female teacher who falls into depravity and becomes a sex slave. She has the exact same beauty as the popular idol! "I'm not an exhibitionist idol like my sister!" They all go crazy!!
