Like a horse of course

Nikki ignored her friend's comment and took her time cleaning herself, careful not to leave any lube stuck under her foreskin where it would cause a most annoying itch if left to dry there. Despite Jessica's teasing, she saw nothing wrong with her anatomy. Yeah, she was more of a grower than a shower, just shy of four inches when soft, but once she was hard she was a respectable six and a half inches, bigger than most guys from what she'd heard.

Not willing to let the matter rest, Jessica continued, "And you were using a pocket pussy. You know, a pussy, like girls have."

Against her better judgment Nikki took the bait, "Yeah, I use a pocket pussy, but it's only because the texture feels so good on my cock, much better than just using my hands. Unlike you I don't have a boyfriend so I have to make due with what I can."

Jessica smiled another one of her sly smiles, "And if you had a boyfriend what would the two of you do?"

"Oh, probably suck each other off for starters," she smiled dreamily, "Maybe try anal."

"You or him?" Jessica said quickly.

"Oh, I'm not sure how I'd feel about a guy doing that to me, but if he let me do it to him I guess I'd have to -" she stopped when she realized the direction the conversation was going, "You're such a pervert, you know?"

Jessica started to say something more, but Nikki cut her off, "And speaking for perverts, did that program fill your computer with viruses or horrible porn?"

"Neither," Jessica beamed, "It works."

"Oh, really," Nikki rolled her eyes as she picked up her boxers and pulled them on, adjusting her balls as she did, "And what did you change?"

"Oh, not much," Jessica continued to smile, "I just made it so you had a cock and balls instead of a pussy and changed it so reality would adjust and you wouldn't think there was anything strange about it."

"You're so immature," Nikki tried not to get mad at her friend, "Teasing me like that. I'd know if there was anything different about me and you know I've always been like this."

"You want me to prove it?" Jessica asked, eyes gleaming.

"Sure," Nikki decided to go along, just to see where her friend was going to take things, "If it really can change reality make it do what I'm sure all the spam emails you'll be getting are going to promise. Give me a bigger cock!"

She burst into giggles after that, unable to keep a straight face in the absurdity of it all.

"Sure," Jessica said, laughing just as hard, "Bigger balls too?"

"Sure, big, bouncing balls filled to the brim with cum and a cock that would make a horse feel insecure!"

"Right away sir," Jessica threw a mock salute and hurried down the hall to the living room. At the computer she clicked a few things, opened some menus and typed for a bit. When she was done she turned to Nikki with a grin, "In a minute you'll be literally hung like a horse and this time you'll see the difference."

"Sure I will," Nikki smiled at her friend and absentmindedly scratched her balls through her boxers, "Until then I'll just stand here in shirtless and boxers looking stupid while you grin like an idiot."

"Yup," Jessica agreed.

"Yeah," Nikki snickered.

"Hung like a horse," Jessica reminded.

Determined to get the last word in, Nikki thought fast, "A real stallion under the sheets."

"Total stud."

"Cock like a -" Nikki stopped abruptly, realizing that her balls were resting heavily against the fabric of her boxers and her cock felt oddly constricted. Looking down she saw that the front of her boxers was bulging, "What the...?"

Hands shaking, Nikki pulled down her boxers and looked at herself. What she saw shocked her.

Her cock was growing before her very eyes, and not in the sense that it was getting hard, more than that her foreskin was darkening and thickening, taking on a mottled appearance. Gingerly, she pulled it back to get a better look at herself and gasped. Her cock head had grown wider and flattened out, no longer looking remotely human. Below her balls were swelling and darkening.

When the changes finally stopped her flaccid cock, was a foot long and if she was sure if she hadn't been so frightened by what she was seeing it would have been even longer. Her grapefruit sized balls bounced against her thighs, aching and full of cum. Through her fear she could tell that it was easily the worst case of blue balls she had ever had. Weak with fear, she fell to the ground, her massive equine cock and balls resting on the carpet.

"Believe me now?" Jessica asked, staring at Nikki's enormous endowments.

Nikki nodded, fearfully, "Can you...can..."

She trailed off, unable to get the words out.

"Change you back?" Jessica finished for her, "Sure."

A click later and Nikki's cock and balls were back to their normal, human proportions. Gingerly, she touched herself, just to be sure everything was as it should be.

"So, Jessica said slowly, "You want to have your pussy back now too?"

Nikki looked at her uncomprehendingly.

"Right," Jessica nodded to herself, "The settings. I put it so you and everyone else would think you always had a cock and balls. You believe me about that?"

Nikki frowned, looking down at her anatomy. This was what she remembered, felt so normal for her that it was impossible for her to imagine having a pussy. Just the thought made her shudder. Having a guy penetrate her...that was frightening, but at the same time she had seen first hand a demonstration of what the Chronivac could do.

After a time she shrugged, "I believe that you could do something like that, but I don't know. I mean I remember always being this way and it feels natural enough. Honestly, I don't think I'd even like having a pussy, sitting down to pee, having to worry about periods, getting pregnant and all that. I like what I've got now."

"Suit yourself," Jessica turned back to the computer, "There anything you would want to change?"

That was an interesting question, one she had never considered before.

Nikki took a deep breath, searching her mind for things to change about her current body. Being comfortable with herself already, the sudden question had caught her off guard. Maybe she could ask for something simple like a hair color change? Even that might be a little weird to deal with, perhaps an eyesight improvement?

While Nikki explored the possibilities of her change, Jessica let out a sigh of her own and started working on something on the computer. Probably watching a video or something, Nikki thought.

After a fairly long silence between the two, Nikki finally piped up. "I don't know, this is still kind of weird for me, maybe I'll let you know what I want to do later."

"Sure, take your time," Jessica replied, looking around the room.
