The first change visible to the tigress, propped up on her elbows, was the fur overtaking Veronica's lightly tanned skin. Black on her forearms, red on her upper arms; white emerging from the neckline of her blosue and spreading up her throat, fluffing out at her cheeks before turning to red again as it reached the level of her eyes. The pattern looked familiar to Jeff, but she couldn't immediately place it.
Veronica's smile grew even more predatory as her teeth sharpened, cnaines lengthening into fangs. A pleased moan escaped them as she felt her body begin to grow in all the ways she'd specified. "God, yes... it's starting..." Reaching up, she undid the first button on her blouse... then stopped.
"No. Let them... rip." Her eyes flared, changing from green to bright gold. Her auburn hair became both more red and darker, like fresh blood. Her hands abandoned the task of undressing, and went to groping her breasts through blouse and bra.
And now Jeff could see what she felt. Muscles developing across her arms; hips and thighs expanding. The straps of her sandals straining against increasingly large feet, then snapping as her heel rose. The tigress gaped as the transforming girl lifted higher, and higher; and not just from the developing hocks. Her legs were rapidly gaining length, even as their curves became more pronounced, Veronica's sensible slacks already close to bursting. Her torso, too, was gaining both in height and breadth, though it did not lose its over-all hourglass proportions as her hips widened with it.
A growl poured from Veronica's throat as she felt it emerging. Her hands dove from her breasts, to her crotch, pushing the wasitband of her slacks to their limit and tearing her panties. She began to pant in lust as balls fell into her quesitng fingers and filled with seed; a sheath growing out from her groin as a new organ took root inside it. Her long tongue lolled from her half-formed snout as she gave herself to the wanton feeling, and fantasies of what she was soon to do to the helpless tigress below her...
Said tigress could not yet see the surprise Veronica had prepared for her; the black-furred hands obscured the growing package. A strange new masculine smell did reach her nose, but Jeff was far too overwhelmed to really register it. The tigress overlaid on his mind, however -- she knew what this foreboded, and Jeff felt his unwonted nethers getting hot and wet again.
Ping! A button ricocheted off the hardwood floor where there was a gap in the carpets. Another narrowly missed Jeff's head as Veronica's bust pushed out, outpacing even her gains in height. And below her first pair of breasts, the blouse was pulling apart to reveal a second pair had formed, dwarfed still by the first but well on their way to B-cups.
More growls poured through her muzzle, now almost complete, as Veronica felt her clothes constricting her. Slender jaws grimaced in pained delight as she took her right hand from her loins; shiny black claws emerging from her fingertips to tear at the seams of her sleeve. The movement itself was enough to to the trick though, the remaining bottuns ripping free as the upper seams burst, letting her tear it away and toss it aside as a useless rag.
At the same time her slacks finally gave up the ghost. Veronica arched her back with a hoarse vulpine yowl, arms flung out and clawing the air as her long, luxurious red and white-tipped brush exploded into being -- and another impressive red member rocketed out in front, its tip gleaming with a whiteness of its own. Her bra snapped and slipped away as her huge rack asserted itself, leaving Veronica completely, gloriously naked.
Oh my God... Jeff could not voice the exclamation, but her eyes did manage to get wider as she took in the revealed form. Veronica had gianed more than a foot to stand at a perfect 7'. She was well-muscled, though sleek rather than bulky beneath her glossy fur and feminine fat. The bottom of a six-pack could be discerned, but it was mostly obscured by the extra breasts -- she now had six, ranging from from F to D, large but suitable to her larger frame.
And then, of course... her dick. Vanilla boy that Jeff had been, she had never really thought of girls with dicks before. But she was going to be thinking about it a lot from now on.
Tall... pointed... slowly broadening down to a thick double bulb... glistening as more precum trailed down it.
Below the awesome spire hung a pair of heavy testes that made the tigress' mouth water and her dual mind burn with shame -- the tiger for losing his manhood to this... this magnificent creature; Jeff just because Veronica's maleness was so much bigger than his old, average human package.
"Yes... oh yes..." Veronica brought her hands back to her body, caressing over her expanded breasts, the red nipples, down over her flanks, her hefty ass. The base of her tail. Then, the best part -- cupping her balls and squeezing at her knot.
"Oh Goddess..." Her eyes closed, breath catching. She even felt a hint of tears as it sank in that this was real, that what she had thought could only be a fantasy was now her.
Then she opened her eyes to gaze down at the slack-jawed tigress. Black-gloved hand ran up her long shaft, stroking out more pre as the twisted smirk returned to her jaws. "You thought I was a freak before," she said with perverse pride, tail swishing behind her. "What do you think of me now?"
"I.. uh..." Jeff swallowed. "I think you're... you're beautiful, Miss Veronica..."
Miss Veronica? he questioned mentally. But he was far more worried by the fact that he did actually find this multibreasted, animalistic hermaphrodite beautiful. Was that just the program controlling his thoughts, or... did he really...? No, not the program, because the formerly dominant male tiger was also appalled at succumbing to the sexualised allure of this femme. This...
Vixen. It finally clicked in Jeff's brain what Veronica had become, from her black ears to the fluffy red tail to the black claws digging into the carpet with barely-held desire.
"'Miss Veronica.'" The vixen repeated it aloud, with a sinister giggle. "I like that... but I think I like 'Mistress' better. Or I guess 'ma'am' might do in a hurry... what do you think, my little kitty girl?"
Jeff choked. It was technically true though -- Veronica's metamorphosis had made her both slightly taller and slightly more muscular than the reduced tigress. This isn't right! complained his tiger identity, and Jeff couldn't agree more. But what she said was "I... I think it... really suits you... Mistress."
This drew a surprisingly sincere laugh from Veronica. Power-play TG fantasies aside -- and beneath her bored bourgeois exterior -- Veronica was not really a bad person. And she thought that this was (more-or-less) what Jeff wanted, not at all realising that he was at the mercy of a computer program forcing him to react in a way she found sexy.
So she squatted down on her haunches, reaching forward to affectionately stroke the fine fur of Jeff's boobs. "So, this isn't so bad, is it? You'll be a furry through and through in no time..." The mischief crept back into her voice as her other hand stroked her cock. "Once I'm done with you."
The tigress moaned at the touch and the promise of more, while Jeff withered in fear and humiliation. While she had wanted -- sort of -- to "get some" on her first date, this was not what she had had in mind. At all. She -- no, he -- was a red-blooded boy and he wanted to be in charge, dammit!
But... Jeff had to admit there was something sexy in having the girl of his dreams dominate him so utterly. In seeing Veronica revel in the power Jeff had given her, and use it to tame the former male.
"And what shall I call you?" the vixen was continuing. "Certainly not 'Jefferson.' Not any more."
"J-Jeff?" the tigress suggested meekly, not bothering to correct the mistake in her name. Veronica snorted.
"Is that cute and feminine? No. Mmmm." She lifted her hand from Jeff to tap claw against fang. "How about... hm. Fifi? No, you're not a poodle... Do you have a middle name?"
"Monroe?"
She laughed. "'Jefferson Monroe.' What parents you must have... Anyway, I think I've got it. Fern."
"Fern?" echoed Jeff, blinking. Fern... To his horror, he -- she found the name already started to feel like it belonged to her.
"It sounds a bit like your old name, and I've always thought it very pretty. Wild, yet gentle. And very suited to your striped coat, you cute little kitty."
I'm a TIGER! But Jeff felt herself blushing. "You're right -- of course, Mistress. It... it is a pretty name."
"So that's settled then..." Veronic shifted, stretching forward to lay atop the tigress, chrring in delight as her strong, voluptuous body made contact with the tigress' soft flesh. She ran her long, pointed snout across the tigress' blunt muzzle, reaching to scratch behind a rounded ear as she whispered into it. "There now... See? Doesn't this feel good? "
Fern shivered. It wasn't so much the touch on her senstive ear, or even Veronica's seductive voice. She was very aware of her four boobs meshing with Veronica's six... and even more of that long, thick, hot rod pressing against her groin.
"It... it feels very... goooood..."
Hearing Fern's whisper trail into a whimper of need, Veronica lifted her head to smirk down at her. "Ohhh? Does my kitty want some love?" She flexed her hips, grinding her shaft up the tigress' belly.
A shy smile curved the tigress' lips before another lustful mewl slipped through them. Oh God no, please no! She can't take me like this! I -- "Y-yes, please, Mistress --!"
Veronica laughed, enjoying her power over the horny tigress. "Really, I should punish you for being such a jerk earlier. But, you're so cute; maybe I'll forgive you... if you're a good kitty."
"I-I can be a good kitty! Please, Mistress," Fern pleaded. Letmego getoffme -- "S-stop teasing -- take me!"
