Phantom Mother - Sons' bodies beyond loneliness

My husband was kind to me when we first got married, but now he doesn't even come home. I feel lonely living like that... That's why I didn't feel any guilt when I hooked up with my son Natsuki. But when my younger brother Yuki found out about it, I was filled with guilt. So from now on, I'm going to treat Yuki the same way I treat Natsuki... My body belongs to my sons...
