A close family on a hot spring trip. Father and sisters. "I have a medicine that will help you beautify your skin," he tricks his daughter into drinking an aphrodisiac, and she goes horny and attacks her father! "I don't care if it's your dad or whatever, I just want a hard dick~" she says, sucking his penis with a glazed look in her eyes, while her father bites into his daughter's soft tits! A group sex with his daughters that he's dreamed of!
