Fair Exchange
Christy kept telling herself that she wanted to see how far Nathan would take this joke of his. Besides, if this just turned out to be little more than a well-thought out sexual fantasy that had impressed more than a few girls at school, she could handle a bit of harmless fun. Nathan was handsome, and if he weren't such an outright playboy in the hallways between classes, he could actually be charming.
Then again, Christy knew why she was really standing in his living room, waiting for him to return. The girls at school, the ones who threw themselves at him, raved about how their beauty and self-confidence were all thanks to Nathan. She just figured that they simply took on entirely new attitudes after being molded by an attractive man such as Nathan in exchange for their virginity. Surely no one is ever the same after their first time.
But then Christy examined from afar a sophomore named Sara. She went to Nathan just four months ago, and the weeks that followed saw a slow but dramatic change in her. In that time, Sara's short, curly hair turned into long, beautiful brown strands. Her eyeglasses were gone and so were her conservative clothes, replaced by more revealing garments, showing off her subtly soft skin and feminine musculature. For sure, no one had ever desired to date a geek like Sara, much less sleep with her. Now she was going out with guys almost every week of the school year.
Christy had no problem taking the boys from school and wrapping them around her little finger. But after having been dumped by Timothy, she was free to satisfy her morbid curiosity and discover, once and for all, what Nathan was up to.
He stood before her, wearing nothing but a thick, heavy bathrobe.
"I hardly expected someone like you to come calling," Nathan said, "You're one of the more popular girls in school. You don't need me."
Christy scoffed. "I don't think any of them really need you. I think you just give desperate girls what they want," she said.
"then, if you don't need me, why are you here?"
"Because I want to know...what it is about you."
Nathan stared at her for a moment, after which he began to laugh. It was a hearty laugh that indicated his arrogance.
Christy took offense. "What's so funny?"
"You mean...you don't know?" he said.
"Don't know what?" she asked, clearly building up her frustration, "Look, whatever it is, give it to me. I'm dying to know what you're selling."
Nathan glared at Christy, saying, "Then will you--?"
She clenched her fists at her sides. Her instinct was to tremble at an offer of sex that now seemed unwise. But she didn't want to show fear.
"I've handled boys like you before," Christy said.
Nathan grinned, and moved closer to her. "No, you haven't," he said, not holding her chin with his fingers, as if to examine a new prize.
"Unlike the others, you're no virgin, but I can like a girl who's already an animal."
He kissed her, at which point she was willing to play along and return the favor. It was a slow, passionate kiss, and their tongues rolled against each other with delicate force until he bit her on the lip.
"Ow!" Christy said, pulling away. She searched the wound on her mouth with her thumb. Sure enough, he had drawn blood.
Nathan licked his lips of her blood, and grinned, revealing sharp, growing fangs peeking out from underneath his top lip. They reflected in the light, for Christy to see.
"What are you?" Christy said in abject horror.
Nathan looked at her with a possessive stare, even as he walked past her and over to the window to pull away the blinds. The scene outside showed a nighttime sky, complete with a full moon showing its face about the rooftops across the street.
"I'm a werewolf," Nathan said as a growl developed in his voice, "I pass the curse onto others, in exchange for a night of passion following the change. As you can see from my others converts, the constant transformation every full moon has...lasting effects."
Christy gasped, watching Nathan part his robe, enough to reveal a thick patch of fur, growing at a constant pace across his chest, soon to expand to his extremities.
"You're a monster," she said.
"As you are now."
Christy was terrified. "You bit me!" she exclaimed.
"Don't be scared," Nathan said, now trying to sound less intimidating, "For three nights every month, you must endure the hungers of the animal. The rest of the time, you will enjoy your new body. Who knows how much more glorious than you are now!"
Nathan dropped his bathrobe entirely, as his chiseled abdomen and well-defined arms and legs became covered in thick, pitch-black fur.
Christy slowly backed away from him, not knowing what else might happen to him. Already, though, she was working up a sweat. The room was not this hot before. But as she wiped her brow of sweat, the heat within her intensified. Short, prickly, stubble had formed on the edges of her face, brushing against her fingers as she ran her hand down her cheeks.
"I have to get out of here," Christy said.
"I'm sorry," Nathan replied while lying down on the floor while the transformation wracked his body. It was clearly becoming more and more difficult to speak. "The doors are...locked from the outside, and - uh! - I can't unlock them until morning. Only t-to protect innocent people from my curse."
Nathan sighed out of pleasure, as he enjoyed a visibly painful transformation. "Ohh, yes! Yes!"
"No!" she cried.
"Don't be - ooh - too upset. You'll understand when...your transformation is complete. Arrr...personally, I alrrready think you're a-a grrorgeous creature. Can't you - ahh - already smell my arousal?"
By now, Christy was breathing rapidly, and from the heat of Nathan's transformation, a curious scent filled her nose. It was powerful, enticing and seductive, all at the same time, and as her mind became overwhelmed with new and uncontrollable sensations, she could only identify it as something she wanted more of. That overloaded her sense of fright.
"Please..." Nathan said, "I suggest you, ohhh...change in the bathroom, and lock yourrrrself in it. Until the animal is unleashed, you're - arrrrr - still fresh meat to me!"
It was little more than a jeer, Christy thought, something to taunt her as he laughed in his now guttural, snarling voice. But she heeded his advice and bolted for the bathroom. She shrieked once as it was apparent that Nathan had made a half-hearted attempt to get up and follow her, but as she slammed the door behind him, she felt no relief even as she was left to herself.
The werewolf scratched at the door with great fury. The animal wanted her. Soon, she would become an animal as well. But the infection could only travel through the body so quickly, so the transformation would take a bit of time to acclimate to the new body. Christy looked in the mirror. The changes on her face appeared to take place more slowly than that of Nathan's. But already she felt different.
Christy tried to undo her blouse to examine how else she would change. Her nails were already sharpening themselves, and made it difficult to use her hands to unbutton her dress. She was now quick to anger, and after the first few tries, she ripped it open in frustration. She was not as delicate with her jeans, shredding it with her new claws and tossing the large portions of them aside.
Smooth, wavy golden hairs, matching the ones on her head, grew from underneath her skin. They were most dominant on her chest, but they also grew from her armpits and between her legs. Her curiosity was automatic, and her claws dug into the fabric of her panties and tore them to pieces. The hair on her pussy was the most developed, turning into a clean patch of fur that spread onto her legs and around her belly button. The transformation, while still slow, was accelerating.
Christy was astounded by the fur growing all over her body, while it was the first time that she noticed that she had grown a foot in height. Coupled with her amazement was the intense pressure building on every muscle in her body. The pain was intense but manageable as bones cracked and muscles shifted to adjust to a new shape. If she wanted to control what was happening to her, Christy could no longer do so as she felt helpless and frustrated.
The moonlight poured into the small window of the bathroom. It was bright and it called out to her, and she wanted to escape from her prison. The window was too small and too high up, and on the other side, the door was well guarded by a hulking, furred monster.
"Chrrrristtttyyy!" a pained voice bellowed out. It no longer sounded natural, but Nathan's voice frightened and aroused her at the same time.
Christy looked into the mirror again. The last vestiges of her human form were still there, but slowly fading away. Her eyes, once a deep brown, were now a bright yellow. A tear fell down her cheek as a snout pushed outwards.
"I...can't...control it!" she cried, then fell backwards onto the floor. She squirmed uncontrollably as the changes occurred in earnest.
As her mass continued to increase, Christy felt the pressure most on her breasts, which had still been cupped by her bra, now under considerable stress. She pulled at the straps but they would not give. Only the size of her shoulders separated her bra from her body. She rolled onto her chest while cupping her nipples to feel how furred they had become. It was fortunate that she had the instinct to change positions, as a tailbone revealed itself, developing it's own skin, then fur, then an inclination to wag about freely.
Christy grunted and groaned as the transformation continued. It was painful to undergo the changes, yet there was a peverse enjoyment to it all, and Christy was fearful of such a duality. How much of her humanity could she retain during the full moon?
That there would be any remants of her human intellect at all was in serious doubt, as Nathan banged on the door again, this time with so much force that it was amazing that it had not yet fallen off its hinges. What he would do with her next was unthinkable, at least for the moment.
Then came a final thought, as the last of the werewolf took over: Christy would be aware of the entire experience, and there was little she could do to restrain herself.
"AaaaaaarrrrrrrRRRROOOOOOOO!"
The hinges on the bathroom door finally gave way, but it was Christy who pounced on Nathan, as both tried to assert themselves as the dominant partner.
"You did this to me!" Christy said in anger. Hers was a deep, dark voice to which she could still not get accustomed.
They rolled around, with Nathan putting her on her back. "Did you like it, then?"
The new werewolf didn't hesitate. "Yes."
"Then...you will like this even better."
Christy didn't see it, but she felt it. His long, thick cock emerged from his furry sheath and entered her tight pussy. She groaned in anticipation of the powerful thrusts his body would transfer onto hers. They locked muzzles together and kissed as they continued thrusting as one. She could feel a fire burn within Nathan's chest as a wetness developed between her legs every time his small, developing knot brushed her insides.
She bit down on his neck, waiting for release. Blood ran down Nathan's shoulder, arousing the two werewolves even more. A wave of ecstasy washed over Christy as she squirted cum across Nathan's furry thighs. She howled intensely as she let herself go.
Panting for breath, Christy looked up. She had not felt Nathan unleash his juices. She glanced at his gigantic penis, which was not spared the effects of the transformation. It had swelled since the rise of the full moon, and it swelled some more while inside of Christy. "What? Why did you stop?"
"So you can turn around."
Instinctively, she did as she was told. He had more experience as a werewolf than she did. In one quick motion, Nathan entered her from behind, and the sensation was just as incredible. Their thrusting accelerated as they continued to move back and forth, building up pressure and heat to levels Christy had never before realized.
Finally, a wave of hot spunk shot into her, overwhelming the newly-created beast with intense emotions and complete ecstasy. She came one more time, all over the floor underneath her.
All this time, Nathan had been restrained in showing any emotion, but his howl shook the walls the moment his knot penetrated Christy. At erratic intervals, they howled in pleasure in between deep breaths for air until the sensation subsided, and the two collapsed into slumber.
* * * * * *
Christy shot up from what was a fetal position. She was naked, and felt embarrassed as the sun shone in from the window into the living room in which she was bit. She tried to orient herself to her environment. The couch was soiled with blood and other fluids, as well as what looked like pieces of meat, which came from a refrigerator whose door was ajar in plain sight from where she sat. The furniture was moved all about, no doubt by what she and Nathan had done during the night.
And there was Nathan, standing over her, wearing the same bathrobe he had used the night before. She cupped her breasts with one hand and covered her vagina with the other.
"Nathan!" she cried.
Christy compared her condition to his. As she gathered her memories, she remembered suffering a second bite wound from Nathan during another session of lovemaking. His teeth marks were still visible on her arm. She was covered in traces of blood and her skin was irritated from dried cum. Yet Nathan took the time to wash off and dress himself, and still found a moment to peacefully watch over his new convert, who was both grateful for their mating and frightened by her new condition at the same time.
"You're one of us now," he said.
