They Keep Their Original Bodies But Switch Genitals

"...so that way you have your body, and you're pregnant, and everything's copacetic, right?" Lois Lane said.

The demon in the reporter's body sniffed. "I mean, you'll still have a dick."

The reporter's eye twitched. She stared down at the crimson cock, which was still stuffed into the pussy she'd impregnated.

"I'm sure I can manage with this for nine months, or whatever."

Blaze gave another sniff. "Well...I can try. It's a pretty complicated spell though. Things might go wrong."

"Define 'go wrong.'" The reporter asked. "I mean, are we talking transporter accident on Star Trek, or what?"

The violet eyes stared at her strangely. "I don't know what that is."

Lois shook her head. "Just...what kind of things can go wrong."

"The reproductive systems are all connected with other things. It's not like just moving my cock and balls and your vagina and uterus over...and I haven't done this before. So we might end up with a bit more of each other than just that."

The reporter let out a breath. "Well, that's not so bad. As long as I'm back in my old body, and look like myself."

"I think I can manage that," she reached down and rubbed her stomach. "But the uterus is the priority, right? If I am pregnant, I want to keep the baby."

"Sure," Lois said. "That's fair. So what do we have to do?"

"Just stay still for a moment. Try not to move. Or cum." Blaze closed her eyes. She placed her left hand on her stomach, just below her navel; her right hand she placed on the reporter's abdomen, just above the root of the reporter's demonic dick. Lois watched in fascination as the lips moved, as if practicing, and the pussy squeezed even tighter than before. Tighter and tighter, until pain shot through the penis, and Lois was convinced the cock was about to be squeezed off...yet she stood as still as possible.

Finally, Blaze whispered a single word:

"Shazam."

Black lightning erupted from the ground, engulfing them both.
