Yumiko, a badass chick on a mission, slips into a naughty cosplay outfit to expose the truth about her husband’s frequent business trip. While he’s out there faking a business trip, Yumiko takes matters into her own hands and sneaks into a costume sale, armed with a secret weapon – a buzzing vibrator that’s about to send her pleasure levels into overdrive. As Yumiko gets her kicks from some steamy low-angle shots of her clueless hubby, the vibrating sensations of the toy drive her to the brink of ecstasy. along comes Kazuya, a smooth-talking scumbag, who whisks her away to the men’s room. Little does she know, her husband walks in, oblivious to the wickedness about to go down.
