Get Boosted - Part Two

Zoe waited in the living room as she heard the front door opening. As she heard a grunt of effort, then the sound of something heavy landing upon the hallway floor.

"Zoe? I'm back! I got you the drinks you asked for."

The tigress, all eight and a half feet plus of her, crouched and remained tense. Primed and ready to move, but silent and still for now as she listened to Ryan returning to the car no doubt for another case of her precious Tiger Power. Behind her, the room was a wreck. The couch, the coffee table, the chairs, all of them were lying upon the floor in pieces; unable to stand up to her weight as she had leaned upon each of them in turn to provide herself some purchase for her frenzied masturbation. Littered around the room amongst the ruined furniture were her sex toys, or at least, her former sex toys. Several plastic cased vibrators lay on the floor with their plastic casing cracked and the motors and wires within hanging out. A metal vibrator lay close by one detached arm of the couch, its once smooth, flawless length not just dented but bent at an unnatural and unintended angle. A rubber dildo, the largest toy Zoe owned, lay forgotten by the mantelpiece. Not broken, simply useless. Utterly unsatisfactory for the tigress' new, far superior body and its obscenely most vast and discerning needs.

Between Zoe's legs now, abandoned but still dripping with the juices it had been eagerly drawing forth until the tigress' sharp ears had heard Ryan's car pulling into the driveway, was her boyfriend's baseball bat. Thank god he'd kept it in the garage with the rest of their gym gear, not in their bedroom or elsewhere in the house. Zoe looked back at the rear of the room, where she had entered through the kitchen and its adjoining door to the garage. She saw the door hanging off its hinges, and shuddered as she considered that she had been holding back at that point, having not only ripped the garage to kitchen door off its hinges entirely as she tried to open it, but ripping out a chunk of brick-work too. Her body was too strong. Too big and powerful for this pathetic house. But for now, she had to restrain herself.

She had to keep herself hidden, and keep her destruction minimal so that Ryan would get close enough for her to pounce upon him. So that he wouldn't have a chance to run, or freak out, or do anything other than what she needed him to do.

Clearing her throat, trying her very hardest to sound normal... or rather, to sound like the normal version of her prior, pathetically weak human self, the tigress called out through the closed door to the hallway.

"I... I'm just sorting something out in here. Don't come in, I'm right behind the door. Just wait there, okay, baby? And... while you're there, why not try one of those Tiger Powers. You won't believe how good they are, I promise."

The tigress shuddered as she thought of all those bottles waiting for her on the other side of the door. She felt her claws digging into the carpet, and barely held back a grunt of loud and obvious ecstasy as a thick spray of lustful juices gushed from her thick, swollen and clutching pussy. Her ears twitched again as she heard her lover chuckle, then she heard him move. She heard the rustling of plastic, and a gentle pop as he no doubt prised the first bottle free from its casing. For an instant, just a split-second, she was overcome with jealously. Why should he get a single drop?! Why was he deserving of any of it when only she knew its true glory. But, that feeling passed. Instead it was replaced by a renewed hunger not only for more of the body boosting drink, but for her boyfriend's body too. Not his current form, handsome and strong as it had been to her human eyes, but what he could become. What she would help him become.

She heard the sound of a cap being twisted open and off.

She heard lips parting, and with her face pressed up against the doorway she heard the first gulp as Ryan swigged from his first bottle of that heavenly substance. He seemed to pause for a moment. He smacked his lips together, and then, to Zoe's joy, he went back for another gulp. And another.

And another.

He withdrew it from his lips, and she heard his breath through the door; ragged and harsh.

"F-fuck... that... that's really damn tasty. Hits the... t-the spot, after lifting all those cases in and out of the car."

Zoe said nothing, just kept on listening as she heard Ryan screw the bottle's lid back on... only to unscrew it again a moment later and take another draught from within. Then another.

"H-holy... Zoe, you said how good these were, but I didn't realise. I didn't think t-they could be. That... a-anything... fuck. Oh, damn. I... I think I need to get changed. Go out on a run or something. I feel pumped. I f-feel..."

A deep, rumbling, savage growl escaped the tigress from behind the living room door.

"Boosted?"

She questioned seductively, and purred as Ryan gave a muffled murmur of assent through another mouthful of that first bottle's contents.

"Mmhmm. F-fuck yeah. I feel boosted. L-like I could do anything."

He gulped again. Loudly. Gasping shamelessly as the sound of an empty bottle tumbling to the floor echoed through the hallway some moments later.

That was it. The cue which Zoe had been waiting for.

She pounced.

She crashed through the living room door like it was made of matchsticks, the frame creaking and tearing itself from the wall alongside the remains of the door, and hammered into the side of the stairwell. The tigress left a shoulder-deep imprint in the painted wall, and with flecks of cream emulsion resting upon her rusty orange furred shoulder she fell back onto all fours, the only way she could move freely in this confined space, and grinned at the stunned look upon her boyfriend's face.

He regarded her as he clutched a second, as yet unopened bottle of Tiger Power in one hand and his crotch in the other, holding the outline of his rapidly hardening erection through his dark slacks.

He stared at her furred but still obviously muscular, near nine foot tall frame. At her huge but firm breasts, at the tail rising, twitching eagerly above her taut ass, and her face. Her grinning, bright and wild eyed face.

"Z-Zoe..."

He moaned as his hand left his throbbing crotch, hard not because of her, but because of what his other hand contained. Still staring at the tigress as she prowled closer and closer to him, the human male opened the second bottle of Tiger Power with a hiss of carbonation. He held it to his lips, and as he began to slurp it hungrily down a small wet, glistening patch began to spread over his slacks' front. Pre-cum poured from the tip of his member as he stared at the woman he loved in her new, vastly more powerful form, and his cock strained more urgently than ever within its fabric confines as that second bottle fell empty to the floor, the tigress' nose now mere inches away from where the male's member was twitching and drooling in desperation.

She watched, eyes wide and focused tightly upon the man she loved as he grabbed a third bottle from the open case. One of no less than six sitting upon the floor near their front doorway. She watched as he opened it, began to raise it towards his lips, then stopped.

He stared at her, as though truly seeing her for the first time. As though until now he had thought her to be some sort of vivid hallucination or simply some lustful fantasy conjured by his sudden, intense arousal.

He smiled, and though Zoe could see the agony upon his face as he did so, the human male reached out with the bottle in his hand and offered it to the tigress instead of taking even a single sip of it himself.

"I... I think I see why you wanted me to bring these back for you, Zoe."

The tigress growled, and with the most delicate and gentle touch she could muster she plucked the bottle from Ryan's hand. She moaned loudly as she held it. A feeling of completeness washed over her. Of satisfaction and joy, just from feeling another full bottle of Tiger Power in her hand again. She drank it. She gulped it down without hesitation a mere moment or two later, and only when it was empty did she notice that Ryan had grabbed a fresh bottle for himself and started to chug it in time with hers.

He handed her another bottle as his own third tumbled empty to the floor, plucking another from the case for himself immediately. They beamed at one another as they chugged them, and Ryan grunted as the wet spot on his slacks grew larger. Obscenely so. His hips thrust forward against the air, and his eyes seemed to clear for a moment before glazing over in a whole new intensity of lust.

"O-oh fuck. I... I'm g-gonna..."

He collapsed forward, dropping to his knees and flinging an arm instinctively around the tigress' neck for support as the other clutched at the still not quite empty bottle of Tiger Power. He quaked and gasped as he filled his underwear and slacks with thick ribbons of cum, driven to orgasm without more than a few early squeezes to his throbbing arousal. Only when he was done cumming did he lift his head from where he had pressed it into the soft fluffy fur of his lover's shoulder, and he stared at her in bashful wonder as he gulped down the rest of his latest bottle.

"I... I can't stop it, Zoe. I need to... I... h-have to... "

She mewled happily at him. She nuzzled against him, and nodded eagerly.

"I know, baby. Don't. Don't even try. J-just... just get those fucking clothes off right now, and I promise, I'll make it better. I... I'll give you the workout of a lifetime."

Zoe more than lived up to her word in the minutes that followed. And the hours beyond that, too. She let loose a roar of giddy laughter as no sooner had Ryan pulled off every last stitch of clothing he was wearing, he flung himself at her. On more than one occasion in the past their fucking had begun as more of a wrestling match, both delighting in their partner's strength and agility, but never before had they taken it to quite such an extreme as they did on that wonderful day. No longer did Ryan have to hold anything back for fear of harming Zoe, and indeed although she was immensely careful and delicate to begin with it didn't take long for the tigress to realise that despite his physical changes not having commenced quite yet her man's figure was still far more solid than it had been. Able to withstand her touch without buckling and breaking not only if she was gentle, but even when she reacted naturally.

She shrieked with delight as Ryan pinned her down by the sternum, hand pressed tightly just above her huge firm breasts, and plunged his cock into her pussy as her hips arched up to meet his own. He fucked her so hard. He thrust against and into her with such force that the tigress knew her human body would have been thrashing and sobbing in pain, but now it only brought her pleasure the likes of which none of her exercise fuelled masturbation earlier that day could even come close to touching in scale. With a roar of orgasmic bliss she wrapped her legs around the male's waist, rolling him onto his back and grabbing another bottle of Tiger Power as she began to bounce and ride him relentlessly. She pressed it to his mouth and made him drink, watching him gurgle and almost choke on the sweet, glorious liquid as he poured another load of cum deep into her pussy, but not daring to spill a drop of the intoxicating liquid any more than her depths were willing to let a single droplet of his cum escape their clutching inner walls.

As they drank more, bottle after bottle of that potent and undeniably addictive drink, they fucked and fought harder. All of it was done with love, of course, and had either one asked for a moment of respite it would have been given without question, but neither one of them even considered seeking mercy for even a moment. They craved physical exertion, and unwilling to stop fucking and pleasuring themselves and their partner for even an instant, that body wrapped around theirs was the only source they had to exercise more of their bodies than just their hips. Thus, they wrestled. They fought on and on in a battle of dominance that was worth nothing but bragging rights and the choice of position. They flung one another into walls, cracking paint and smashing bricks beneath. They tore paintings from the walls. They smashed bannisters and what little home furnishings existed in the hallway of their home. And finally, with an almighty roar from Ryan as his half-formed muzzle threw itself back in another orgasmic release, his rapidly growing, ever more muscular body lifted his lover clean off the floor and flung her not back but upward with such force that the ceiling itself suddenly began to find itself pock-marked with the same dents and holes that were increasingly common across the walls of the wrecked hallway.

" Yes! Yes! More, baby! More!!"

By the time they were onto the second case of those that Ryan had brought home, he too was now in his true form. A body deserving of these feelings, a body worthy of the admiration and lust which boiled inside the tigress writhing up against him. Zoe screamed as she rode her boyfriend's thick cock, feeling it seeming to grow larger, thicker still practically each time she lifted herself up and flung herself back down upon it. She clawed at his furred chest, leaving drag marks but not piercing the skin despite the carpet and the wood beneath it either side of them being raked by deep, obvious gouges. She drummed her fists against his shoulders as he grabbed her by the thighs and bounced her roughly upon his cock, shrieking and wailing as he pumped a seemingly endless flood of hot cum into her while driving her to orgasm after savage, unstoppable orgasm.

The two tigers fucked as hard as their new bodies would allow them to, and harder. They pushed themselves to the limits, and each time they found those limits all it took was another bottle of Tiger Power each to to push them further still. It didn't matter that they had both transformed, that they were both nine foot powerhouses of muscle and pleasure now, they could both feel the potential for more. So much more was still waiting to be unlocked inside each of them, and all they had to do to seize it was drink.

" Harder!"

Zoe roared as Ryan crashed through what remained of the wall between the living room and hallway, their shoulders tearing through the ceiling and the floorboards of their bedroom above as he stood with his lover in his arms, claws dug into her tight ass as he lifted her up and down the vast, thick length of his cock with ease and yet the same fevered intensity he might once have used to lift weights. With every round of orgasms, every round of Tiger Power they guzzled down, things just got better. It didn't matter how many times they came together, there was always a next orgasm to look forward to. A bigger one. A more devastating one to truly push them to their physical and mental limits. An orgasm worthy of the bodies that were enjoying them.

There came a point however, a point during the time when Zoe and Ryan realised that if they did anything more than lie still and hump one another senseless they might well cave in their entire home around their fourteen foot tall bodies, when even the most devastating orgasms did not seem like nearly enough. Still they felt there was more they could feel. More they could experience if only they were able to boost themselves enough, but... what? What could possibly feel any better, any more incredible than all they had already experienced thanks to the Tiger Power coursing through their veins?

The question was answered, of course, by finding out. By drinking more. Cases number four and five were gone in a matter of minutes, bottles not twisted open now but torn open by sharp and huge carnivorous teeth, the content dumped down the throats of the two tigers one after the other after the other in rapid, shot-like succession. They lay together as they gorged themselves upon their personal twenty four bottles, side by side across the length of not just the living room but the entire lower floor of their devastated home, plaster and broken wood and concrete tumbling down upon them from the wrecked ceilings above as with each motion of their trembling forms the whole house creaked with structural uncertainty. As the last dregs of those bottles were consumed however, the two tigers lay panting and trembling. They didn't immediately resume fucking once more. They didn't set about one another with wild, re-invigorated savagery despite the fact that the passion and energy that had been coursing through them from the very beginning was still utterly unabated, indeed stronger than ever.

They lay still, panting and clutching at one another by a single clawed hand alone, because of a new feeling. A new and rapidly building sensation that was even more powerful than the desire to act, to burn some of the energy surging within them like the white hot plasma of a sun. There was something inside of them, and it was fighting to get out. Fighting to be known, recognised, and acted upon.

"I... I f-feel..."

Zoe moaned first in admission of this incredible and overwhelming new sensation, but in a matter of seconds she was reassured as Ryan snarled desperately back at her.

"Me too. It's... o-oh, fuck... Zoe..."

Their hands parted. With a fresh roar of pleasure both of Ryan's hands flew to his chest, clutching at his pecks as beneath the surface of those rock hard muscles he felt something shifting. A boiling, bubbling sensation like his insides were liquifying and re-forming into something else. Something better. At the same time Zoe's paws flew not to her breasts, but to her crotch. Cupping her mound, clutching at the thick, swollen outer lips of her pussy and the prominent clitoris which stood out at a size that was probably close to the size of her fist back when she'd been a human. She could feel a throbbing deep inside herself. But not from her pussy. Not from her separately aching, needy clit. A throbbing like the pounding of drums, drums that were growing ever closer in their announcement of something arriving. Something building. Growing inside of her.

She looked to her lover, and at almost the exact same moment Ryan looked at her.

"H-hold me..."

She wailed as the feeling grew and grew, almost terrifying in how intense and incredible it was; like no sensation she had ever been able to experience before that very moment. And he did. The other tiger wrapped her up in his arms as they rolled onto their sides, and with arms and legs encircling the other feline's vast and powerful body, they began to shake. To tremble, to thrash, and to grow once more as the final changes took place to grant them the ultimate bodies, the ultimate forms worthy of two such dedicated drinkers of Tiger Power.

They roared, they screamed, and they laughed as their bodies grew through their former home. Bigger and bigger as these latest changes overtook them. Their bodies swelled, shifted, they changed in shape and form beyond anything since the initial switch from human to tiger, and as they burst up and out into the cool evening sunlight, the remains of the building tumbling off around them as they writhed and squirmed, the pair of twenty foot tall and still growing tigers kissed one another deeply.

"Y-you feel... incredible..."

Ryan snarled as he felt his girlfriend's cock rubbing against his own, so hard, so ready even though it was brand new. Every bit as long, every bit as thick and hungry for stimulation as his.

He wriggled against her. He rolled over, pinning Zoe to the rubble of their home, and as somewhere close by he heard a tiny, utterly pathetic human cry of shock, he shifted upon her until beneath his heavy and swollen balls he could feel the tigress' brand new cock rubbing up against the already dripping wet lips of his own brand new pussy.

"Fuck me, Zoe."

She was already thrusting, already humping upward against him as he begged, and mere moments later Ryan grunted anew in even greater ecstasy when alongside her bucking against and into the man she loved, Zoe found herself compelled to crane her neck up and press her muzzle to one of his huge, firm and equally brand new breasts.

The two vast tigers growled and moaned as they began to fuck together in this new and overwhelmingly different way, Ryan barely able to focus enough to lift himself up and down the length of Zoe's cock while he tried to deal with the feeling of her maw suckling so tenderly upon his breast. It might have been somewhat easier had it just been pleasure, but from that source just like all the others provided by the boosting energy of Tiger Power it felt like there was still more to come. And sure enough before long both tigers wailed in shock and glee as Zoe felt something beginning to dribble out onto her tongue. Something that gushed from the nipple held firm between her lips as she hungrily, lovingly suckled on it, and filled her with an unbearable joy as it flooded down her throat.

Not milk. No milk could ever taste this amazing. No substance other than that which Zoe now knew she would never again have to be without.

Tiger Power.

Ryan was leaking, he was lactating pure, fresh Tiger Power.

"Oh god. O-oh... god... yes!"

And soon, as Zoe rolled her lover over and began to fuck him somewhat harder while granting him access to her breasts in turn, she could feel the same rich substance gushing from her own nipple into his hungry maw.

Somewhere in the wreckage of their home, buried beneath their huge, writhing and pleasure stricken bodies, a single intact case of Tiger Power remained unconsumed. But no longer was it necessary for the two of them. No longer was it required, for Zoe and Ryan were no longer dependant on the pre-bottled stuff. They had one another now. The only source they needed not just for love and affection, not just for pleasure and a physical workout to put all others to shame, but for more of the incredible substance which had gotten them this far too.

And as they pleasured one another, as they lay there amidst their neighbourhood, fucking and roaring with absolutely no regard for their tiny human neighbours, they kept on drinking. They kept on gulping it down between more focused, frenzied bouts of fucking back and forth to try and keep every aspect of their lustful bodies sated, all the while feeling a certain, undeniable truth continuing to bubble and flow deep within them.

There was still more to come.

More to explore and to feel together. And all they had to do to achieve it was keep on drinking from one another. Keep on pleasuring one another.

All they had to do, was to keep on getting boosted in the only way that made sense now.

Together.
