I want to be Urara's child... Whenever I go to get pampered, my sister always gives me her nipple. In front of our mother, she pretends not to get along, but when it's just the two of us, she nurses me. While we're eating dinner as usual, my mother says, "Kanon, you were holding hands with a boy, weren't you?"... I'm confused for a moment. (I can't forgive a man I don't know for pampering my sister's breasts... I can't forgive that.) That night, in the room, I push my sister down and do more than just breastfeed her. "Stop it, big brother! We're family!"
