Stretch Test

"Every sample of red kryptonite is a little different—every effect is unique." Mercy said. "We've actually tested this before, on our previous subjects. So we know exactly what it does...and its limits."

Lois said nothing, only held the rod inside of her while Mercy was talking. "So what does it do, Graves?" She could feel it start to vibrate as it did something, but Lois couldn't actually feel what it was doing.

"For Kryptonians, this activates a metagene similar to that possessed by the Elongated Man. Did you ever catch that sex tape that hit the deep web?"

Lois hadn't broken the story, but she knew what Mercy was talking about. Metahumans were still people, and people still made the occasional decision to record themselves having sex, or the misfortune to be caught having sex and filmed in the act—there were entire websites devoted to such "superporn" although most were quietly taken down rather quickly; if heroes like Cyborg and Oracle didn't catch you, there were villains who had been rumored to kill those who created, distributed, or even hosted such materials. On the deepweb were perverts **** or devoted enough to risk the wrath of gods and monsters to collect and trade their superporn.

The Elongated Man could stretch his body well beyond the tolerances of normal flesh and bone...twist and contort himself as if he was a boneless, promethean thing. No one knew what his real limits were, and nobody had known what that meant for his sex life...until someone shared a hidden camera clip of the Elongated Man's wife, wearing a horsecock dildo, slamming it home like she was grudge-fucking him for something. It was like some real-life otaku fantasy of o-ring orifices and impossible penetrations come to life. Normal people could, with excessive training and preparations, maybe take such a toy, though they risked permanent damage to do so.

These two though...they had just been banging away. Lois had looped the clip. The rubber bitchbreaker should have snapped his sphincter like a rubber band, ruptured his colon, and gotten lodged in his pelvis as it plowed far past any pleasure sensors he had and smacked into his lower intestine. She could see the distension in his stomach with each thrust, and wondered at what queer distortions his anatomy must be going through, that she could see the head of the two-foot long rubber erection clearly outlined through the skin of his stomach, despite all the muscle and integument in the way.

And they had both been into it, Lois knew. She couldn't see his face, but she had heard the Elongated Man gasp, his dick swinging so hard it slapped into his stomach, a constant trickle of cum leaking from the flaccid dick as his wife rode his ass...and her face Lois could see clearly, the quiet mask of almost mania, plowing his rubbery ass for all she was worth, her whole body contorting, abs flexing as she tried to plunge it in deeper and harder with every thrust...

Lois, shivered, feeling herself get a little excited at the memories...and then blinked. The vibration of the rod was much more noticeable now, and it felt less comfortable. Before, it had hardly been noticeable, but now... Lois looked down...and gasped.

The reporter shifted, the rod a bit less comfortable inside of her...and then the pieces clicked together in her mind. She stared down at the rod, which was no longer the size of a toothbrush in her hand. The black rod had begun to inflate, and was already an inch in diameter, pushing against her internal walls, spreading her pussy lips apart.

"Don't remove it, Lane." Mercy warned. "We're still collecting data...and you have a long way to go."
