An Shinohara is the type of girl who is absolutely submissive to her boyfriend, her obedience absolute and unwavering. She naturally follows his commands, acting exactly as he desires. In this scenario, An has a vibrator secretly placed inside her underwear, placing her in an extremely unusual situation, and is then led outside. The location: the hallway right in front of her apartment, where immediate handjob awaits. Without a trace of doubt in her boyfriend's words, An obeys without question—her every action driven solely by the need to fulfill his demands. However, what her boyfriend truly desires is for An to have sex with men other than himself. Unaware of this truth, An continues to follow his orders blindly. Will she ever be able to have sex with her boyfriend again? The answer lies in the outcome created by his intentions and her complete submission.
