"My breasts actually make cum."
"Cum?" asked Jon. "As in, sperm? Like a guy's sperm?"
"I've had it tested," said Tabitha, "and as far as any of the doctors can tell, its normal, healthy sperm. Its identical to the sperm a man's testicles make, except made by my breasts. Its even genetically mine, in the same way my ova are."
"Could you get a girl pregnant with your breast cum?" asked Jon, curious and disgusted at the same time.
"I'm not totally sure," answred Tabitha. "The doctors seemed to think that way. Its even theoretically possible for me to take some of my breast cum and use it to fertilize my own eggs, getting myself pregnant. I could be both the mother and father of my children." Tabitha giggled.
Jon stroked Tabitha's breasts as he thought about this. Tabitha's beautiful breasts gave life in a different way than other women's breasts did. Instead of nourishing babies, they could actually bring babies into the world. Jon was fascinated by the possibilities.
