Centaur Palpation

Mercy had a big bottle of lubricant in her left hand, and began to apply it to the gloved right arm.

"And where do you think you're going to stick that Mercy Graves?" Lois said.

"It's called palpation, Lane. Very standard equine veterinary procedure. I need to probe your rectum. Don't worry," she smiled. "I'll be gentle."

"Not going to happen." Lois said, defiantly. On her new legs, she was taller than Mercy...and she had a feeling that a kick from her hooves would give Lex's bodyguard a new attitude. The reporter circled away from Mercy, tail flicking angrily.

"It's a medical procedure. We really are worried about your health. I promise you that," Mercy said, as she finished lubing up her right arm, and set the bottle down. "Now you can come over here and we'll get this over with nice and easy or..." Her smiled turned into a hard line. "...we can do this the hard way. Mr. Luthor, a demonstration please?"

Another hole opened in the ceiling, and an arm extended. Another crystal on the end...and the red light was suddenly supplanted by a terrible green glow.

The light was pain. Lois' entire body burned in instant, silent agony...and then it was gone, the arm withdrawing.

"Cooperate Lois. The sooner begun, the sooner done. Who knows? You might even enjoy it."

Lois said nothing, but she didn't say or move as Mercy circled around. "That's it," the bodyguard cooed, laying a reassuring hand on Lois' flank. "Just relax. Be all over soon." Despite herself, Lois found the rub on her hindquarters did calm her down.

Mercy carefully lifted Lois' tail—jet black, like the reporter's hair, but a bit stiffer—to expose her anus and vagina. "Transformation appears complete." She said aloud, presumably so Lex could hear. "Rectum and genitalia have assumed equine configuration." The bodyguard took a deep breath. "I'm going in."

Lois had done a little anal play before. Just a finger, to see what it was like. This was...something else. Mercy had brought the fingers of her right hand together into a point, and pressed them against the round, fleshy donut-pucker of her anus...and the sphincter gave surprisingly little resistance to the lubed-up hand.

Proportionally, the reporter knew that she was now...bigger, down there. Yet at the same time, she had never been fisted up the ass...and Mercy wasn't stopping.

"No fecal matter so far," Mercy said dryly. "Presumably consumed for the transformation. Body temperature is normal for a filly. I can feel the vaginal canal through the rectal wall." Lois pawed the ground in spite of herself, as Mercy continued to go in and in and in, inch after inch...her asshole seemed to gape at it passed the hard muscle of Mercy's forearm and yet it kept coming. The sensation was, like anal play, not entirely unpleasant.

If anything it reminded Lois of an incident during a gynecology exam. A routine pelvic exam, one hand resting on her abdomen, two fingers inserted deep inside her... and Lois had, well, she had came, a little. The fingers had brushed a certain spot deep inside and she had just clamped down and gone fuzzy for a minute. Lois had never been more embarrassed in her life, but the gynecologist hadn't said anything, like it had never happened, and...

"You're getting wet, Lane." Mercy interrupted. And she was right, Lois knew, as a splatter of fluid hit the floor. Graves was in up to her bicep now. "I can feel the uterus through the rectal wall...cervix is open...following the horns...ovaries appear normal. Subject appears to be in estrous." Lois looked back over her bare shoulder, and noticed the sweat on Mercy's brow...and the nipples poking through the top of her chauffeur's uniform. "Alright Lane, all done. I'm going to take it out now."
