A dead-end office worker with an overactive sex drive invites quiet, plain accountant Miu Shiromine out for drinks, hoping to take her home and blow off steam. The moment they arrive, her expression changes and her filthy true nature erupts: saliva-soaked tongue kisses, voracious vacuum blowjobs, and hard spread-leg riding. She milks every drop from his balls through repeated creampie sex, beginning a lust-drenched life with the ultimate kinky fuck buddy.
