National AV actress grand prix winner and mainstream idol Haruka Mizuki delivers 20 consecutive creampie scenes right from her debut! Haruka, working as a bank teller, finds herself in a bizarre situation where she's repeatedly fucked by her perverted S-masochist coworker and an erotic executive. Forced to work while wearing a vibrator, she's tied up with neckties and fucked throughout the office. From the bank vault to the counter, she's subjected to deep throat, excessive drooling, and relentless creampie after creampie. Betrayed even by her boyfriend, Haruka is left sobbing as the semen deposits keep coming—one after another, 20 times in a row!
