It Works—Plus or Minus 2% Body Mass

There was a disconcerting sense of seeing double—as thought Lois was simultaneously staring down at her own body, impaled on the scarlet succubus's crimson cock, and staring up at the dark-horned horny demon that was spearing her pussy—and then it resolved herself, and Lois Lane breathed a sigh of relief as she was in her own body once more.

Well, almost.

The pale plain of Lois Lane's stomach felt sensitive and painful deep within, and down between her legs where there should have been a pussy, Lois now saw a fairly familiar scarlet schlong...and it was embedded in a pale pussy that sprouted from the otherwise blood-red skin of Blaze's own crotch.

The demon reached down and touched her hard abs, poking and prodding gingerly.

"Yes..." Blaze said. "Our reproductive systems have switched. Had to include some of the surrounding tissues, so that might be sore for a little bit. I think the embryo is intact."

"Well...that's good," Lois said. She felt oddly hot, almost feverish. Her new genitals felt itchy and hot...the erection hadn't gone down at all. "No chances of tissue rejection or anything like that?"

"No..." Blaze said. She drew backwards, gasping slightly as the cock slipped out of her. It was still throbbing hard, the veins along its length almost purple. Black jizz dripped from the demon's human slit. "...but there are going to be side effects."

"Like what?" Lois said. She raised a hand to wipe sweat from her forehead. It was definitely hotter in here than she had realized. Her whole body felt like it was burning up.

"Well, when you got my cock and balls...you also got the blood that was coursing through them. Demon blood. It's in your body now."

"What...what does that do?" The reporter's eyeballs felt hot, her heart raced. Blaze pushed the reporter down against the bed and straddled her, lining the still-stiff cock up with her cum-filled pussy.

"Well, you'll heal faster. High a higher than normal body temperature. Your blood will boil in holy water. Immune to most human diseases..." The demon licked her lips as she slid her pussy down to engulf that cock. "...and I can make you hard whenever I want."
