In an office setting, Yagoto Rara Mizuki, a petite Japanese secretary, is initiated into a taboo world by her dominant boss. He orders her to strip and suck his cock, she complies, her skinny body trembling with excitement and fear. She drools and gags on his thick member, her first time experiencing such a lewd act. Her boss, unsatisfied with her hesitant performance, pushes her head down, fucking her mouth until she gags. He then makes her swallow his hot cum, leaving her gasping and disheveled, a newfound lust burning in her eyes.
