My wife and four kids, 40 times a day, having sex. ZUKO-057

Your new husband brought four troublesome kids with him. Your wife went back to her hometown, so you can't afford to neglect teaching them a lesson today. There's the gloomy eldest daughter Ayumi, the dim-witted college student Yuka, the rebellious Mao, and the possibly gender-disordered Miku… To maintain your father's dignity, you'll have to spend the whole day using your penis to properly discipline them.
