A Horse Dildo

Mercy Graves left the centaur reporter on the floor. Lois Lane swished her tail in frustration. Her body was hot. She wanted to run, to gambol, to...to find something that filled the gaping need burning inside of her. But there was little she could do, right now. She would have to go through with these experiments if she had any hope of becoming human again.

So Lois watched as the bodyguard went to a section of wall no different from the others and pressed...something. A panel slid aside, and from a depression came forward...her heart skipped a beat.

It was longer than the reporter's arm, and at the widest thicker than her bicep. Her horse-stomach fluttered as she considered the long, dark length of it. Some matte-black silicone modeled from life that preserved every vein and ridge, the flared knob with its promise of scraping out a mare's insides, and extended straight from the wall with no droop or sag.

"On your feet, Lane," Mercy commanded. Lois found herself climbing onto all four legs with alacrity, not even needing to stop and think about how her legs should go. Her tail swished harder.

"Over here," the woman said.

Lois trotted over. She knew, deep inside, that she should be this excited. It was just a dildo. One that she'd never even consider trying to take, if she was a human woman. Size queens be damned, there just wasn't room inside of her for such a beast under normal circumstances. Right now though...the centaur figured it would fill her out like an application.

"Turn around, back up. We need to get this at the right level."

Obediently, the reporter pivoted. It really was amazing how easily the footwork was coming to her now, like her body knew what she should be doing. Briefly, she wondered if it had been the same when she was a baby learning how to walk...and then there was a palm on her huge equine ass, Mercy holding her at arms length as she adjusted the height.

"Good," the hand slid off of the fur-covered backside, gently touching the reporter's flank. "Back it up slowly. As far in as comfortable to go."

Giddy with excitement, Lois Lane began to walk backwards..and felt almost immediately that distinctive bulge of the horsecock against her nethers. Panting slightly, she pushed, letting her weight and mass come to bear...and it slipped in, almost effortlessly.

Lois Lane made a sound almost like whinny. Even though she had just orgasmed, the horse cock dildo was thicker than Mercy's arm...and her body was responding to it, to the shape of it. Biting her lower lip, Lois gathered herself together and took another step back...and another...feeling inches of hard cock split her equine cunt open.

In her shower at home, Lois had a dildo with a suction cup on the end that she liked to attach at times to the wall. To back down onto it slowly, feeling her artificial lover fill her up. This was like that...but there was so much more of it, and she could feel every hard inch of it inside of her.

After a long moment, Lois felt her ass-cheeks nuzzle softly against the cold wall. She could feel the slight vibration of machines through her cheeks, powerful engines or motors buried behind the white wall.

Out of curiosity, ever the reporter, Lois Lane was compelled to ask. "What's the purpose of this experiment?"
