Ruka, a newly hired employee, possesses a huge ass and massive boobs that are obvious even through her suit. Before officially starting, she attends a live-in newcomer training at the company dormitory. That night, when her boss peeks into Ruka's room... he finds her masturbating in a full-body see-through bodysuit that reveals every curve of her body! Ruka's secret way of relieving stress was wearing body stockings! Having discovered her secret, the boss takes advantage of it, threatens her, and forces her into a blowjob without question. Thus begins the "sexual service" disguised as "training"... Clothed masturbation, blowjob ejaculation, titjob, jackhammering cowgirl, consecutive creampies, facial... a total of 7 ejaculations. 140 minutes of ultra-intense clothed sex with Ruka Itoi, whose destructive, voluptuous body features see-through nipples and a shaved pussy with visible veins.
