Oswald Hendryks Cornelius, an extremely attractive and wealthy bounder, was the greatest fornicator of his time. In this instalment of his scorchingly frank memoirs, Uncle Oswald recounts his discovery of the sexually invigorating properties of the Sudanese Blister Beetle, and his cunning plan to steal what men are most willing to give away. Oswald and his partner in crime, the seductive and beautiful Yasmin Howcomely, travel all over Europe to retrieve the sperm of powerful, rich and artistic men.
They freeze the sperm with the plan of selling it to rich women who wish to create children using the genes of the rich and intelligent.
Oswald's accomplice tried to use the aphrodisiac on King Haakon of Norway, but her plan misfires when she accidentally eats the aphrodisiac carrying chocolate she intended to serve the king. She gets thrown out of the king's castle after she falls into a temporary state of nymphomania
and tries to rape him.
