In order to secure a new contract, Ruka continues to be sexually harassed by the manager of a client company, and reluctantly endures the unreasonable entertainment. However, the manager's demands escalate, and he calls her to a hotel, ravages her voluptuous body, and ruthlessly ejaculates deep inside her vagina without her permission. With both hands tied, he forces her to give him an iruma, a titty fuck, pounding her in the cowgirl position, and repeatedly cums inside her. Ruka gradually becomes more submissive to the manager, and in the end, he forces her to have a threesome with her boss.
