Newly hired employee Sakura is forced to accompany her company on a one-night, two-day hot spring hospitality trip. Under her boss's absolute and abusive authority, she endures repeated lewd torment during the car ride. Upon arrival at the inn, her supervisor forces her into a mixed-gender bath, where he sexually assaults her, groping her G-cup breasts and asserting complete physical control over her. During client entertainment, she's made to serve an older male client she's never met, pushed into deeply humiliating circumstances. Left alone with her boss, even after reaching orgasm, she's violently thrust into repeatedly, climaxing over and over from the relentless pounding by her deeply despised superior's insatiable cock, sinking further into submission. The escalating shame and suffering gradually erode Sakura's mind.
