"Kat took me into her body," Dan said. "For several minutes it felt like I was a part of her. I want her to feel like she's part of someone else. I want you to make her pregnant."
Mom leaned against the wall, rubbing her chin. "That seems appropriate."
"What!" Kat shouted, putting one hand over her groin and wrapping the other arm over her breasts.
"It makes sense," Mom said. "You showed disrespect for another human life, so now you have to be responsible for a baby, with all its needs. But who," she said, turning to look at Dan, "should be the father?"
"No!" Kat barked. "Do NOT let my younger brother make me pregnant!"
"I meant nothing of the sort," Mom snapped, looking back at Kat. "I just wanted his advice. But if you don't keep quiet, I'll ramp up this punishment and make you the mother of an incest baby."
Dan looked back and forth between his mother and his sister. He'd never volunteered for this, but both of them were talking about him like he had no choice over his sexual behavior. "Wait a minute. I said for you, Mom, to make her pregnant, using magic. I said nothing about incest, or sex of any description."
"I guess that's true. But I agree. I'll use my magic to make Kat pregnant, and since I'm a more experienced and powerful witch, I'll make sure she can't use her powers to reverse this effect. In fact," Mom said, pointing at Kat with her wand, "I should warn you that magic is too dangerous for babies. Your powers will disappear while you're pregnant, and maybe even while you're nursing. Congratulations, on your very first day of having your magic, you're about to lose it."
Kat was crying, still keeping her hands wrapped around her sexual parts like a Greek virgin statue. "Don't do this to me. I only just turned eighteen, please don't do this to me..."
"Too late," Mom says. "I've made my decision. You will have to carry a baby to term, and give birth to it, and raise it up the way I raised you. But I still have one question." Mom turned eagle eyes on Dan.
"Who should be the father?"
