An Abnormal Stepsister Family: My husband, a shut-in who has lived in the same house for 20 years, continues to suckle at my older sister's breasts and affirms this dependent relationship. (Rieko Hiraoka, FJIN-050)

I've been living with my husband's family for five years now. The eldest child in the house isn't my husband, but my stepsister, Rieko, who has always lived there. I know my husband has always harbored feelings for Rieko, and he has an unusual adoration for her, like she's the only person he can confide in. But I can't say it. No matter how strange the situation, this is the only place I can stay… My stepsister, I actually know everything. Hehehe.
