How about a pregnant broodmother?

It wasn't something he'd ever so much as hinted at to his wife, but Tom had a massive pregnancy fetish. In fact, he found every stage of a woman's pregnancy arousing. Everything from fertilizing a woman, the beauty of a growing pregnancy, the fecund glory of a woman at full term, and even a woman giving birth, Tom loved it all.

Still, there are several major problems with such a kink, such as the actual time between impregnation and birth, the fact that neither of the Saunders particularly wanted children, and the health risks of pregnancy and birth. Not to mention that very few women would be interested in sexual contact during birth, and that the percentage of women who experienced orgasmic births was very small.

Scrolling through pages of erotic images and stories, Tom came to the conclusion that, if he wanted to exactly define how Sarah would change, it would no doubt take quite a few wishes. Turning the wishing coin over in his hands, he smiled wryly. Alternatively, he could just lay out a broad set of parameters, and let it be a pleasant surprise.

His smile transforming into a grin, Tom flipped the coin that had made all of this possible, and wished that Sarah would transform to suit his breeding, pregnancy, and birthing fetishes without resulting in a multitude of human babies.

Content that his wish would set things on the right course, Tom went to find Sarah, to find out what the result of his wish was.
