To Harvest Stem Cells

"While you might look half-horse right now, you're DNA is still mostly human," Marcy Graves explains. "And you're in estrus. That means you should be able to conceive. We'll let the embryo develop until the red kryptonite effect wears off, and then induce a miscarriage to harvest the Kryptonian-human hybrid stem cells."

Lois shivered, prepared to protest...and then the horsecock dildo inside her began to move.

"Oh!" She was unable to stifle a moan.

Mercy chuckled and ran a hand along the centaur's dark flank. The reporter dug her hooves in and leaned back against the cock, which was beginning to piston in and out of her. It felt so good...and there was so much of it...

No! Think, Lane! She told herself. They're just trying to knock you up and steal your...well...not your baby exactly, but...

Lois Lane's hands found their way to her breasts, squeezing the small tits, pinching her nipples. She couldn't reach anything else, but she could reach those, and the pistoning pecker was speading up. Her massive horse-pussy was growing hot...hotter than when Mercy Graves was buried up to the shoulder inside of her.

...I mean, I don't know if I want a baby, or foal or whatever yet. And it's not like miscarriages don't happen all the time anyway. Something like a quarter of all pregnancies. And I'd be advancing medical science...for Lex Luthor.

The reporter grimaced at that thought, even as she tried to grind her great horse-buttocks against the wall, the vibration of the engines thrumming through her massive pussy, tail swishing like mad. While she wanted to be normal again, she hated the thought of Lex Luthor winning.

"Who...who is the...sperm donor?" she sputtered, still rubbing her breasts. The strokes of the cock were shorter now, and Lois wondered if it somehow sensed how close her own climax was.

"Why, Superman of course." Mercy Graves kept patting Lois Lane's sides. "Does that feel good girl? Are you ready to cum yet?"

"Y-yes..." Lois muttered, feeling her climax rising. "I'm close..."

Superman! Superman's baby! Lois wasn't sure how Lex had even gotten the Man of Steel's super-sperm, but that put an entirely different complexion on the matter. Now she knew what she had to do.
