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'... Whenever I go to act spoiled, my sister always lets me suck her nipples. In front of our mother, we pretend to not get along, but when it's just the two of us, she comforts me and nurses me. As usual, while eating dinner, my mother starts saying, 'Kanon, weren't you holding hands with a boy?'... I'm momentarily confused. (Some stranger sucking on my sister's breasts? That's absolutely unacceptable.) That night, I push my sister down in her room and do more than just nursing. 'Stop it, big brother! We're family!'
