This OVA starts with the premise that the butler did, in fact, do it! Following in the tradition of his butler grandfather, Katsuragi reports for duty as the new butler at the esteemed Tsubarateras estate for his summer holiday. One of his many household duties entails personally seeing to the needs and demands of the spoiled and insatiable Lady Kohota. Without delay, the sexually ravenous debutante takes full advantage of her new manservant and puts him to a test that wildly exceeds all proper butler protocol! As their relationship grows romantically deeper, will her stuffy class-conscious parents ever approve of a young high society woman cavorting with the hired help?
