[Osushi Tabeitai (Yu)] Our Family's Lust-Filled Stay at a Hot Springs Resort [head empty]

Little Mei and her daddy turn a family trip to a hot springs resort into something far steamier than the water, starting with him pinning her squirming legs apart under the futon covers and lapping at her most sensitive little spot until she squeals for him to quit. Even the public bath offers no escape, as he teases her hidden places beneath the surface while casually chatting with the other bathers, who only notice how flushed and wobbly the girl has gotten. Between breathless confessions and her glowing vow that she wants them to be together forever, the only loose thread is her brother Ayumu, who has no idea what really gets his little sister going, and a teasing promise that onii-chan will be getting plenty of attention tonight.
