A continuation of the great Oni Chichi series. This time, our protagonist Airi, along with her lustful father, set off for the hot springs. Naturally, the trip was not without curiosities, but after a certain amount of time, our heroes still reached their destination. A clear and blue sky, charming autumn leaves and of course the hot springs themselves... It would seem a complete idyll, but something still bothers Airi. It seems to be a total idyll, but something still bothers Airi. She is still puzzled by her feelings towards her father. Maybe he is not telling her something, or maybe he just doesn't love her as his daughter without using various pills and love flavorings to make her want to have sex... Based on a hentai game by Blue Gale.
