[Enokoro Kurage (NOSA)] Sono Te Ippai Nobashitara (Love Live! Nijigasaki High School Idol Club) [CrotPedia]

Yu Takasaki sneaks up on a napping Kanata Konoe, kneading the sleeping girl's soft, heavy breasts while giggling that Kanata still believes her little sister Haruka is the one touching her. When Kanata stirs awake, she takes charge instead—baring her chest, letting Yu nurse eagerly at her nipples, and cooing that today is a special day just for the girl who always bothers everyone else. The roleplay blurs into raw need as Yu straps in and takes Kanata from behind, moaning for her 'Onee-chan' while the bed-soaked pair push past the line between friends, lovers, and sisters.
