MVSD-678 - Trained in the back room… During a late-night part-time job… I, a naive and timid person, was threatened by a scumbag manager and continued to be sexually harassed daily in a situation where I couldn't make a sound, and came to know perverted pleasure. Asakaze Yui

The devil's hand of a scumbag manager approaching Yui, a diligent college student working at a late-night convenience store for living expenses. The scumbag manager takes advantage of her naivety and timidity, targeting times when she is working alone to begin sexual harassment. “S-Sir, what are you doing…? Please stop…” “Stop? Is that okay? It must be hard to live, sending money to your mother. You have to pay tuition, and I heard you're even behind on rent… You'd be in trouble if you got fired from your part-time job now, right? If you just listen to what I say, I can give you a raise.” The timid college student, threatened with being fired, accepts the power-type sexual harassment of the scumbag manager in the back room! Daily, vile sexual harassment continues in a situation where she cannot make a sound with customers in the store… remotely! Under the register! In front of customers! In the back room! Endless physical training and peak of shame! Sexual harassment… shame… The college student, turned into a slave at the beck and call of the scumbag manager, falls into the darkness of abnormality…
