A/N: I decided against a sequel to Phony Matrimony, at least for the time being. If more interest is generated for it, I may consider it in the future. I got my idea for this story from a book by Lavyrle Spencer. It's called The Fulfillment. If you can come across a copy, you should give it a read.
Many years ago, Cepheus Malfoy was the head of the Malfoy family. He was a proud and stern man. He believed that there should only be one Malfoy child born each generation. Not only should there only be one Malfoy child born, it should be a boy to carry on the family name. He didn't want there to be any chance that someone would try to take the place of the rightful heir. He married a beautiful woman who he believed would grant him his only heir.
It took a year before she got pregnant. Cepheus was enraged when the child was a girl. He ordered the house-elves to kill her, and he told his wife that the child hadn't made it. They tried again and again. His wife gave birth to four more girls, and Cepheus had them killed every time.
His wife found out the last time what he had been doing. She had never gotten to see any of her children as Cepheus had always whisked them away the moment they were born. She had crawled out of bed and followed him as best she could. She overheard the orders and realized what had been happening all these years. She hurried back to her room before he could notice that she was gone.
Cepheus wanted to try again. His wife was terrified of having another girl only for her to be killed. She made a deal with her husband that they would try one last time. If it didn't work out this time, they would stop trying. Cepheus was desperate to get his son, so he turned to his extensive library. He pored through his books for hours every day searching for an answer.
He finally found it in a rare and obscure Dark Arts book. It was a spell that would last for eternity. It would allow every member of the Malfoy family to only have one child, and it would always be a boy.
