Thirteen girls relate their filthy experiences with spanking fanatic Percy Ottershawm, from his headmaster's daughter to Penny herself. From 1950 to 2000, his life was dedicated to getting his girlfriends across his knee, pulling down their tight white cotton knickers and spanking their bare bottoms. Otherwise, he is polite, considerate and every bit the gentlemen, always willing to indulge the girls' wildest fantasies, from wetting their knickers in the street to being tarred and feathered.
