My family is a so-called big family with 5 older sisters and 5 younger sisters. I'm the only man in my family, or rather, I'm the only one with a cock, so I'm always being sexually harassed by a group of women. One day, the second daughter's older sister got a ticket for a hot spring tour through a neighborhood association raffle, and decided to go on the Akagi family's first family trip... Everywhere we go there's always a naughty storm blowing up!
