[Reducing Mosaic]DASD-689 I want to be my sister's child... My sister who breastfeeds me every chance she gets. Uraraka Haneto

I want to be a child of "Urara" ... My sister always gives me a nipple when I go to be spoiled. In front of her mother, she pretends to be on bad terms, and when there are two of them, she breastfeeds. When I was eating as usual, my girlfriend's mother started saying, "You were holding hands with a boy, weren't you?"... I was confused for a moment. (I can't allow a man I don't know to be spoiled by my sister's breasts...) That night, I push her sister down in the room and do more than breastfeeding. "Stop it, Onii-chan! We're family!"
