姉汁～白川三姉妹におまかせ～

Shirakawa Yu has been residing with his grandparents for some reason, but it's expected that he will live with his mother and her new husband, who is also known as his father-in-law. His sisters-in-law, Kyoko, Ryoko, and Anzu, have grown into beautiful women and are eagerly awaiting his arrival. Upon his arrival, they welcome him warmly and offer him the room of their absent father, who is occupied with archaeological studies. In that room, he discovers a peculiar jar which is cursed and will bring upon him terrible misfortunes unless he can collect the love juices of women within a specified time frame.
