Kallipygos: a naughty story from ancient times.

Kallipygos and her sister were walking home, playfully discussing who had the prettiest bottom. In order to finally decide they stopped a lusty young man, lifted their robes and asked him for judgement. He choose kallipygos; the older sister, and promptly fell in love with her.
on telling his brother of his naughty encounter, the brother went to see for himself ! Having no doubt thoroughly scrutinised the two lovely bottoms, he fell in love with the younger sister. They were all married, and lived happily ever after. Hopefully the two young women got the wedding night spankings they so richly deserved.
