*Just as the filename implies, Tiggs' and Vixy's first time trying the now-infamous Kei Corporation gender change potion, moreover Tiggs herself, and a slight error in judgment is made and found out all too late. Not like that's necessarily a bad thing mind you... >_>; 

	Even though they'd been living together for awhile now, it had taken longer still for Tiggs to even hint, let alone work up the nerve to let Vixy know she was at least curious to know if Vixy was up for some 'fun' behind closed doors, they had been together for a good number of months at this stage, and the very idea of Vixy in 'that' type of situation in Tiggs' mind was more than enough to get the latter quite hot n' bothered. Tiggs' inhibitions had always prevented it, but even after asking one day and Vixy had politely turned Tiggs down on the offer (mumbling something vaguely similar to Tiggs' own apprehensions to the concept of her and Vixy getting 'frisky'), that still didn't stop the large anthro tiger girl for long as she happened to come across an advert for a well-known company known as Kei Corporation. A quick search online and an order from their extensive catalog of 'toys' later, Tiggs was waiting in eager anticipation for what she'd purchased (and being surprisingly affordable no less) to reach her.

	It was literally the next day when she'd received the package containing a small bottle of what was part of the 'potion' line that Kei Corp. produced, and making sure that her plan was set for her and Vixy to have that day at home to themselves, Tiggs went back inside with the item in hand where Vixy sat on the living room couch for Tiggs to stand before her and explain what she'd been up to...

	“Hey Vixy, remember how, uhm... y-you'd said you were kind of, y'know... because we were both...” Tiggs stuttered, stopping before she could verbally finish her thoughts in full before nervousness got the better of her, but Vixy's increasingly annoyed gaze forced Tiggs to speak directly for fear of losing the one chance she might have.

	“A-alright, I know you said you weren't sure about us having, well 'fun' if you catch my meaning, it would be kind of awkward since we've never... I've never been with another girl myself at least, so I thought maybe if one of us wasn't it might make things a little more... what?” Tiggs stopped as she noticed Vixy's usually red face going even redder at what Tiggs was saying, but it didn't add up until Vixy saw the package in Tiggs' hand and the logo it bore.

	“Traci... is... that's what I think it is, isn't it...?” Vixy inquired awkwardly as she recognized the brand name and caught sight of the name of what the box contained, but not quite understanding it was Tiggs herself who was willing to try the potion.

	“What's wrong, I was just gonna at least try it and see if that would help cut the tension a bit, I know it sounds weird but I just... I mean... I-I guess I can always just throw it aw-!” Tiggs began to say dejectedly, just turning to go when Vixy stopped her.

	“Traci, wait don't do that...” Vixy took a deep breath to steady herself at this mind reeling situation, not just from how strange it was (or the fact that it was definitely real, albeit still strange) but past that Vixy couldn't quite imagine how Traci would look as a guy, she was already fairly large, but then would that mean... Another thought sent Vixy's whole face nearly up in flames, if Tiggs was already larger than life as a girl, what would that also translate to when she was a guy?

	“O-okay, let's take it one step at a time and see how it goes at least... I don't know how well your clothes would fit if that stuff actually works, m-maybe you should take them off beforehand...” Vixy said, trying to be sly yet still biting her tongue about doing so if only a bit. Regardless, Tiggs proceeded to nod and nervously strip her clothing off, revealing her nude curvy form for Vixy to eye up in an unexpectedly eager fashion.

	“Okay, it says to gulp it down in one go, here goes then...” Tiggs read aloud as she opened the box to find both a bottle and a set of simple instructions of how best to drink the potion, of which was colored a light pink and visibly glowing softly. She popped the cork off the top and swiftly downed the entire thing wherein the changes to her body took place near-instantly;

	Tiggs' hair remained generally unchanged, as did her more feminine appearance, but that was where any sense of femininity ended as Traci's body went from being soft and curvy to on par with Davin's own, becoming more muscular and toned into pushing body builder territory. Tiggs' tail retained it's usual soft fluffiness, but it was the sight of what now swayed between her, or rather now his legs that Vixy found herself helpless to wrench her gaze away from, the sight of a smooth looking but still massive cock at about 6 inches long and 2 inches thick (even in it's currently flaccid state) colored a light fleshy pink hanging over a set of testicles roughly a size and a half larger than a golf ball each. 

	“So did it w-... oh, I guess it did work... eheh...” Tiggs chuckled nervously, clearing his throat as he was unused to having such a deep voice. Taking a few steps around to get used to the new appendage between his legs, Tiggs failed to notice Vixy's eyes followed every last sway the tiger's giant cock made at each step, at least until he turned back to Vixy to see the obviously interested stare she was giving Tiggs. For some reason that hungry glint in Vixy's eyes was making Tiggs start to have some very new, very odd thoughts in his head, and as his heart rate kicked up from the ideas swirling through his mind the once flaccid shaft began to quickly perk up and grow nice and rigid, twitching and throbbing at it's full height of just over 9 and a half inches by nearly 3 inches thick!

	“(Oh hell, I'm starting to think this was a bad idea, Tiggs is staring me down like I'm her... his dinner!)” Vixy thought to herself, but the last word quickly went from less in the literal sense to more of an innuendo-based one. The growing patch of moisture through her shorts between her thighs revealed her true thoughts on the matter, however.

	“V-vixy, I'm not sure what to do... I...” Tiggs stammered timidly, yet instinct was clearly taking hold as he was slowly but steadily making his way over to Vixy, who could do little more than stare squeamishly up at Tiggs as he stood close enough that Vixy could literally smell the precum positively free-flowing from the tip of Tiggs' length.

	“W-well I guess I should take my clothes off too, right...” Vixy muttered distractedly, the sight of Tiggs as he was now, as a male was doing things to Vixy that she'd never encountered with anyone else, the whole scene was so odd, so left-field and yet Vixy found herself wanting to go along with it all so easily. Though it certainly didn't hurt that she legitimately returned the same feelings Traci had for her as well. Very quickly Vixy's shirt and shorts were off of her body and on the couch cushion next to her, the instant she had her back to Tiggs to set the articles of clothing down however was when Vixy was grabbed up from behind by Tiggs who was clearly tired of waiting for some relief from the unattended raging erection he had.

	“AH T-TRACI WAI-!” Was all Vixy managed to call out before Tiggs' cock was pushing firmly against Vixy's soaked sex, the only effort Tiggs needed to give coming from the tight fit despite the natural lube they both yielded. But Tiggs' new body and it's muscles weren't just for show as he pinned Vixy effortlessly to his chest from behind, and it didn't take much more than a swift thrust of the tiger's hips to jam the head of his cock inside of Vixy. Not stopping to wait Tiggs quickly stuffed the rest of his member deep inside of his smaller partner's tummy, forming a large oblong lump clear up past Vixy's navel in fact. As Tiggs finally crammed the last few inches of his dick balls deep into Vixy, the expression on both tiger and vixen was one of glazed over bliss, and Tiggs whole body began to go on autopilot to make the first few awkward and unrefined thrusts into Vixy, causing the bulge his cock made in her belly to glide up and down with each pistoning motion of his hips.

	Deep inside of him, Tiggs could feel some kind of odd pressure welling up with each forceful thrust he placed into the one person he loved the most, the warmth of her body and her soft moans with each bucking thrust he placed into her and even the sheer size difference only served to accelerate those motions and approach steadily closer to what Tiggs knew in the back of his mind what was to be the first orgasm he'd experience as a guy. 

	The final straw was the thought that almost literally meant Vixy was his first time in at least a couple regards, one with Tiggs as a guy and the other the first time Tiggs had ever been with a girl as either gender, and that's when the pressure peaked and Tiggs pushed his cock as hard and deep into Vixy's twat as far as he could, followed by the strange alien feeling of the veritable firehose of cum pouring up from deep inside of the weighty balls between Tiggs' legs, up the whole length of his cock and out the tip to flood Vixy's belly full of Tiggs' first load of hot, thick, sticky feline semen.

	Despite all of that, as the high of their combined orgasms tailed off and faded, it became clear Tiggs was still far from done having fun with Vixy, the still rock hard erection he had was more than enough proof of that fact, and as he pulled it free of Vixy's thoroughly used cunt, another, even tighter hole a bit further back had caught the tiger's attention. The sheer power Tiggs' new body had was as astounding as it was addicting, especially to Tiggs who found himself going over to place Vixy on the couch and flip her over to hold her ankles up and out in a vice-like grip, lining up that massive throbbing tiger cock with Vixy's tailhole.

	“Oh shit... T-Tiggs c'mon, that's not gonna fiIIIIIEEEE-AAAAAAAhHHhhH-OHMAHGAAAAWD!” Vixy wailed as Tiggs proceeded to shove the tip of his dick against the much smaller orifice, pulling Vixy's ankles back toward him for leverage until it inevitably popped inside, and Vixy's head flew back in a wide eyed and open mouthed silent squeal, thankful at least for the sheer amount of fluids already coating Tiggs massive girth and length, but the sheer tight fit and fullness being made in Vixy's belly over and again as Tiggs began to thrust his hips hard and fast only sent more of the vixen's juices down to keep things nice and well lubed up, and after a moment Vixy had finally relaxed enough to look back down and see the massive bulge in her gut Tiggs member made, the head prodding well above her navel once more with each jab her lover made into Vixy's ass, those big balls slapping into Vixy's rear each time.

	As Vixy looked back up at Tiggs' face though, Vixy was astounded to see a leering, almost dominant grin on the tiger's face. A far cry from the timid and cuddly tiger Vixy had known for quite some time. To be honest it was also a somewhat welcome change under the circumstances, it would have been a bit trying to do most of the 'heavy lifting' with Tiggs as 'she' was even now. It was then Tiggs shifted his grip abruptly from Vixy's ankles to her wrists, holding them up and above her head with a single hand, the other reaching down and around behind Vixy's waist to keep her in a position for Tiggs to  keep ramming his cock home nice and deep into Vixy, and Tiggs was so close to another orgasm it was all he could do to not lose himself entirely in the moment.

	“N-next... your mouth Vixy... I wanna feel your tonNNNGGgHH!!!” Tiggs said in a gruff, hoarse whisper as he curled forward to put less than an inch between he and Vixy's noses, followed shortly by a firm kiss to Vixy's lips, quieting any further wails of pleasure from them both. It was then Tiggs at last climaxed to bloat Vixy's belly up with another load of his seed, the amount not being any less than the first time and all the while giving that same leering, assertive grin. Vixy had been shocked to hear something like that come out of Tiggs mouth no matter what the context was, but it was clear Vixy's mouth would be a bit too preoccupied very shortly to say anything one way or another about Tiggs' almost 180 change of attitude. As Tiggs pulled out to let the majority of cum spill out of Vixy it was clear that the third load Tiggs would unleash inside of her wasn't likely leaving the same way it went in, unlike the first two times.

	Vixy was flipped up and onto all fours with Tiggs' member so close Vixy could easily have slurped the tip with her tongue, but Tiggs was after far more than just that as evidenced by how he braced Vixy's head in his iron grip and pressed the tip against Vixy's lips. To keep from hurting them both Vixy reluctantly opened her jaws to let the head of Tiggs' cock get engulfed in her muzzle, then push even further back until Vixy felt the back of her throat being forcibly stretched from Tiggs' rigid shaft. With a bit of effort Vixy managed to give a good swallow, finally helping Tiggs along, and Vixy felt every last twitch and throb the massive pink member made as it was shoved further and further down.

	Before Vixy realized it, her nose was ground firmly against Tiggs' groin, the fur being of an exceptionally soft quality, but Vixy could also feel Tiggs lean over and pull the vixen's tail aside for something to share the fun; a bit of kitty-grade cunnilingus. The sensation of Tiggs' rough feline tongue lapping in a soft, loving fashion at Vixy's sex combined with the first few pistons Tiggs hips made Vixy was dangerously close to losing it, losing her mind under the wash of emotion she had since all of this began, all she could think of now was helping Tiggs get off as best she could from her 'bottom' position, and Vixy's tongue poked out to slide along the underside of Tiggs' smoothly textured length, easily gliding up and down and serving to speed up what was to be Tiggs' last climax for the moment.

	Tiggs himself couldn't keep from having a bit more fun with this odd feeling of being 'in charge', while not quite on a power trip per se the feeling was quite intoxicating, and taking both index fingers he gently spread Vixy's swollen slit to grind his tongue between those warm moist folds. It was when he crammed every last inch of that tongue inside of Vixy that Tiggs could no longer hold out, a deep rumbling purr emanated from her and resonated through her whole body and, by sheer proxy it was felt by Vixy as well, mainly where Tiggs' tongue lay buried to prompt one last powerful orgasm from them both. Vixy's tummy swelled and sagged nearly to the cushions she was on, thankful when Tiggs pulled out and sat up on his knees, pushing Vixy up onto the couch facing him to spray a few ropy spurts over Vixy's face and upper body, and even a few drops landed on her breasts.

	“Mmph... geez Traci, I have to say that was... well, if it weren't for everything else, I'd be tempted to ask if you'd stay like this for awhile, 'intense' doesn't-... what, what's with that look?” Vixy said breathlessly before a look of mild horror crossed Tiggs' face.

	“I... forgot to order the reversal 'antidote' potion too...” Tiggs said sheepishly as Vixy stared at him in disbelief, of course if anyone would forget something as crucial as that in a moment of excitement, it would be Tiggs.

	“Please don't be mad, I can order it now and it'll be here tomorrow, same as... Vixy?” Tiggs started to say while getting up to head to the computer when he was stopped by Vixy giving his dick a gentle tug.

	“W-wait... there's nothing that says... you have to change back so soon, right?” Vixy said awkwardly, her heart beat pounding loudly in her ears as Tiggs looked down at her excitedly.

	“Y-you mean it... you really want me to stay like this for a little while longer?” Tiggs inquired hopefully, to which Vixy nodded in a reluctant but honest answer of 'yes'.

	“At some point though...” Vixy said with a sudden, growing devious grin, her fingers cinching down around Tiggs' dick a bit more firmly.

	“You're letting me 'drive', even if it means I've gotta tie you to the bedposts... or would you even be into that sort of thing?” Vixy added more in general than directing the last part at Traci, being genuinely unsure until the excited, grinning blush on Tiggs' face gave Vixy her answer.

	“Hmmm, I don't think we'll need to worry about you turning back for at least a few days then, if you don't mind?” Vixy asked, getting another nod and Tiggs' shaft beginning to stiffen back up at the flurry of thoughts swirling through her mind at what Vixy had in store for him. What exactly those things were however is, no pun intended, another story for another time.
