Kelsey stared blankly at the trio of green pills in the palm of her hand. She stood at the kitchen sink, a glass of water in her other hand. She was considering her options, and the consequences of those options.
The pills must have worked. She felt great before and after track practice, hardly losing her breath. She had improved her time a great deal. And look at Paige, she was greased lightening now.
Yes, look at Paige. Kelsey wouldn’t mind the abrupt muscle tone and incredible speed, but what about Paige’s sudden homosexual outburst? Had that been an effect of these pills? Kelsey wasn’t a homophobe, but a sudden urge to masturbate in public could lead to some difficult situations.
Kelsey tossed the three pills into her mouth and knocked them down with water, before she could reconsider. The back of her mind had decided that she had a stronger will than Paige, and could handle any ‘urges’.
Once again, Kelsey’s stomach gurgled and rumbled. She felt slightly nauseous for spilt second, but that quickly went away. The hairs on the back of Kelsey’s neck prickled, her skin felt uncomfortably warm.
“Oh, I knew I shouldn’t have taken three!” Her back against the cabinet, Kelsey slid down to the floor, overtaken by a sudden dizzy spell. “Ug, thank god mom isn’t home…” she said as her vision blurred.
Kelsey groaned when she felt her sex moisten. Why was it happening now?! Kelsey then realized she shouldn’t complain. At least she was in the privacy of her own home. She struggled against the urge to pleasure herself, gritting her teeth, telling herself over and over it was filthy and wrong.
“I-I just need to distract myself… I’ll… I’ll go for a jog!”
Kelsey stepped out her front door wearing a short pair of spandex running shorts and a sports bra. After a few preliminary stretches, Kelsey slowly jogged towards her favorite route, a small dirt road a few hundred yards down her street.
The small road led to several farms and fields, most containing alfalfa, with a few cows and horses thrown in. Kelsey enjoyed the area; it was to home and quiet, with few near death experiences with cars. Just the occasional farmer driving slowly in his truck, giving a friendly wave as they passed.
All of Kelsey’s problems were all but forgotten as she neared the halfway point of the dirt lane. Kelsey was truly enjoy herself when once again she felt her sex moisten, dampening her running shorts. “Oh, no, no, no…” Kelsey slowed to a stop, her hand migrating to her groin.
Breathing deeply, something was in the air, something was driving her rapid rise in libido. Glancing down the road in both directions, Kelsey then ducked into the brush lining the road. Hating herself, Kelsey reached inside her running shorts and began massaging her aroused clitoris.
“Ahh… ahhhh… ah…” Moaning, Kelsey slowly lowered herself into the brush and grass. Between pangs of euphoria, she tried to understand what was causing her strange reaction. It was the scent! She decided, the scent, a musky, rich odor was driving her wild as she rubbed her sex with one hand and a breast with the other.
The pheromone began growing stronger, powering Kelsey’s fingering of herself all the more. “I’ve… I’ve got to stop!!!” She cried out, but couldn’t despite her best efforts. The scent only became stronger, force more juice from the girl’s cunt.
A loud bark was the force needed to break Kelsey’s fingers from her pussy. Spinning around, Kelsey found the source of the noise, large Pitbull just a few yards behind her, his upper lip raised, nostrils flared, and his immense organ hanging half erect beneath his belly.
“Ohhhh!!!” Kelsey groaned finding a powerful need for him. “I… can’t believe… I’m doing this!” Kelsey said as she clambered over the barbed wire fence. The dog was skittish at first, confused with the strange mixture of human and dog scents and body language, but his own needs, wants, and instincts over powered them.
Dropping her running shorts, Kelsey was shocked to see the changes that taken her sex. Her bushy, black brush gone, replaced by short coarse fur. Kelsey watched as her clit pulled inwards growing into a teardrop shape and leaking arousal; eager for a male.
“Oh, what the fuck!!” Kelsey groaned and bent over, presenting herself to the dog. The beast drank in her scent, a long lick across her pussy and cold wet nose touching her ass. Kelsey shivered as she felt his panting, hot breath blowing across her nether regions. The stud cared little about the transformations taking place to what he thought was a bitch, about the tiny tail swishing between her buttocks, or broadening hips, or her feet growing into paws inside her running shoes. He simply had one thing in mind.
Kelsey quivered as the powerful animal straddled her, feeling his warmth, the brisling of his fur against her back. “Gah!” She called out as his stiff member began its entrance. It was tight, but with surprising care, the pitbull pushed into the dog-girl. As her cunt squelched, he began thrusting, making the teen scream as he plunged into her.
“OH… OH… OH… No, oh gees… OH!”
Being too distracted be the happenings in her pussy, Kelsey didn’t notice as her $300 running shoes spilt, revealing her strained socks, containing her new paws. The dog panted loudly, drool dripping on the dog-girl’s neck as Kelsey’s muscles gained strength, allowing her to sensually manipulate his shaft.
The pitbull’s load exploded into as Kelsey climaxed once again. “Oh god…” She murmured as the beast pulled his softening member from her, failing to knot the bitch, their combined juices sliding down Kelsey’s now furry legs.
Kelsey fell to the ground, exhausted. The dog sniffed her dripping pussy giving it a lick and left, laying down nearby to clean himself. “Oh, god… what have I done!” Kelsey moaned. She reached down to her groin, wishing to wipe away the sticky slime, only to find that her body had been drastically changed.
“What the hell happened to me?!” Kelsey said as she sat up. Her jaw dropped as she looked at her body. “This… this can’t be real!!! This can’t be happening!!!” Her legs were entirely those of a pitbull, covered in sleek grey fur, with paws just like the animal she just fucked.
“Oh, jeez…” Kelsey moaned again as she felt her thin grey tail twitch and swish behind her. To top it all off Kelsey found a row of bitch teats, situated on her abdomen. “Dear god… what do I do? I’m a… I’m a dog-girl!”
