Ubukata Susumu

A seemingly average boy he's told by Koko that he's special and has a very high chance of making girls pregnant. So the goddesses Koko, Ryuuzu, and Hisui all move in to his house to make babies.

Although he loves living with the goddesses he would still like to have a girlfriend. But can he really have a girlfriend when he's secretly making 3 goddesses pregnant?
