妾二十一人　ど助平一代

Teppei Omori is a man of extraordinary virility, with 21 mistresses, over 30 children, and more than 1,100 women he has had relations with. Teppei's daily routine involves visiting each of the beef hot pot restaurants, "Akasatana," run by his mistresses, to collect the sales and keep an eye on the women. One day, Noe, one of his mistresses at the first branch, announces that she wants to marry Urakawa, the chef. The other mistresses, in the prime of their lives, can no longer be content with working for him only once a month, and they compete for Teppei's attention, cheating on him behind his back.
