■Currently, I'm One-Year-Old

A physical relationship between a bloody brother and his sister. Since having sex with my sister for the first time, I have never been contraceptive. A younger sister with an inflated lower stomach recently. I may have gotten pregnant, but I'm afraid that I can't find out. Two people at a hot spring inn where no one knows their sister who knew the pleasantness of sex. She and her sister, who are suspected of being pregnant, continue to live without contraceptives.
