Endo Aiko is a slim, submissive office worker with a seriously filthy side. Her boyfriend works at the same company, stays constantly horny, loves risky play, and even has a cuckold fetish. To relieve the stress of middle management, he slips a remote-controlled vibrator beneath Aiko’s miniskirt and toys with her pussy while she tries to work. He enjoys watching her panic and make mistakes, then makes her suck his cock with other employees still in the room. Although Aiko initially worries they will be caught, her submissive side soon takes over. She licks all the way down to his balls and begs, “I’m getting turned on... I want your cum.” After she sucks him off, they both feel completely refreshed. Their daily games take an unexpected turn when the company president summons them and shows them kinky photos of Aiko that someone emailed him. As he demands an explanation, the cornered couple must face what happens next.
