Starting with the shocking premise of a perpetual low-ranking employee secretly opening a female-oriented adult service, this work unfolds an unexpected encounter with a female superior during a 120-minute cunnilingus course. The intense content, where she is licked into submission until she pleads, 'Please, just insert it already...', doesn't forget the service spirit of cumming inside. It's a work that deeply immerses in female-oriented adult services, relieving the only stress of a capable female superior whose boyfriend won't lick her, through consecutive orgasms from cunnilingus. The thorough cunnilingus, repeatedly licking the pussy and even inside the vagina, drives the female superior 'Tsumugi' to lose her rationality from overstimulation, and her request for raw sex is a must-see. Tsumugi's performance, capable of an astonishing range from dominant to submissive, is perfect, and the long-unseen submissive setting is surprising. The sight of Tsumugi loving to be licked, endlessly licking the clitoris in a show of eroticism, and the blissful moments of seeing close-up shots of Akari Tsumugi-chan's breasts make this the ultimate work. Personally, I'd be happier with a few more close-up scenes, but the satisfaction level remains high.
