Imouto Jiru Episode 1

Akira's father, an archaeologist, has remarried, giving him a new stepmother and three step-sisters: Yuki, Nana, and Miu. While on their honeymoon, Akira's father makes an archaeological discovery and decides to stay at the site to supervise, leaving Akira at home alone with his new family members. After being found in bed with his stepmother, Yukie, Akira discovers a box containing a scroll and three bottles. Using the knowledge his father taught him, he reads the Sumerian language on the scroll and finds himself bound by a contract with the goddess Inana, who tells him to collect his sisters' love juices in the bottles before the next full moon or a terrible horror will befall him. - Nonton Imouto Jiru Episode 1 Sub Indo di Hentaicop
