my good motherinlaw, fuma yumi.

Akira and Shinji, sons who do not like the new mother 'Yumi'. One day, two people witnessing the husband and wife's activities are stimulated by the turbulence of Yumi that they see there, and use it to target their bodies. It was a reluctance to accept it because I wanted to be recognized as a family, but gradually I felt pleasure in being good for my two sons.
