Zettai Harem

A high-school boy named Shikazono Hare is chosen to take part in a scientific pregnancy experiment, requiring him to live with four women and sleep with them. The group consists of Samara, a young woman in her early twenties with the most experience; Mikoto, an energetic and tomboyish girl; Kaya, a shy individual with hidden sexual tendencies; and Ayaka, Hare's childhood friend. Hare's life quickly changes as he is surrounded by these four women, leading to a dramatic shift in his daily routine.
