As soon as she pulled them on Allison felt something wrong. The jeans felt tight before she even zippered them up, as if her legs themselves had grown larger.
“What’s wrong with these things?” she said as she barely managed to close the button. “They’re so tight! Ow!” Allison gasped as pain leapt from her tail bone.
“Huh, my jeans are tight too.” Gina answered. “Maybe it’s the weather.”
“The weather? Pfft, maybe that’s why we’re fucking animals too. C’mon, help me feed Duke. The horny bastard’s earned it.” Allison said with sarcasm as she pulled her shoes on, which also felt uncomfortably tight.
Both girls could have sworn they felt their clothes tightening as they gave the horse fresh oats and water, but neither wished to speak of it, uncertain of the cause. Finally, a loud rip spoke for them.
“What was that?” Allison said.
“Shit, my pants… what the hell?” As Gina turned Allison saw that the girl’s jeans had spilt along the seat, but that was not the matter of concern. Revealed along with Gina’s red thong, a thick lock of glossy black hair also peeked out.
“What the fuck is that?!” Gina gasped. As she plucked at the hairs, it suddenly struck Allison what they resembled.
“It’s… it’s a horse’s tail!”
“What?! Shut up!”
“Look at Duke’s, you idiot! Oh…” Fearing the worst, Allison opened her pants and felt her rear. Sure enough, she also sported a tail like Gina’s, only red.
“What’s happening?! Why?” Allison barely finished her sentence when she heard Gina call out. Her friend was leaning against the fence, a look of pain on her face.
“What’s wrong now?!” Allison shrieked.
“My feet! It… It feels like my shoes will explode!” And explode they did. The seams at the sneaker’s toes could take no more. They burst open at nearly the same moment. “Oh, fuck!” Gina swore. “Those cost 80 bucks!”
Allison looked at her in amazement. “You’ve got a lot worse problems than that! Look at your toes you idiot!”
“Huh?” Gina stared at he toes; the large lumps hidden beneath her socks reveal that not all was right. The socks began to rip, exposing hard shiny hooves. As Gina began putting more of her weight on the new appendages, her already tattered jeans tore and ripped as her legs changed shape. As the last remains of Gina’s pants and thong fell to the floor, Allison could now see her friend’s new, reconfigured anatomy. From the waist down, Gina’s body appeared to be that of a small, naked horse and that hairlessness was quickly changing. Radiating from her groin and hooves, Gina’s legs rapidly grew a pelt of sleek, black fur.
Gina felt the new fur on her thighs, amazed by its smoothness. “This is so… weird.” She flicked her small tail, exposing the black skin of her vulva and anus to Allison.
“Stop that!” Allison snapped concerned with the changes she felt inside her pants. She plopped herself on the ground, tears welling in her eyes. “You’ve just turned into a freak and all you can say is ‘this is weird’? By god, you’re an idiot.”
“Hey!” Gina scowled. “So what if I enjoy it… a little. I’m not the one that fucked my neighbor’s horse!”
Allison started crying immediately. Realizing what she had done, Gina clopped to her friend’s side. “Allison, please, I’m sorry…”
“It’s alright, I understand… oh, ah! Help me get these shoes off! Hurry!” Gina rushed to pull her friends shoes off. She barely managed it in time finding her fingers stiff and unresponsive. Gina could barely grasp Allison’s socks with before they ripped open with Allison’s new hooves.
“Damn, there go your socks.”
Allison snorted. “As if it matters, oh… My jeans are going to go soon… horses don’t need socks, or pants, for that matter.” Allison muttered as she pulled away her torn jeans allowing both her and Gina to watch as her legs became covered in dark red fur.
“C’mon, Ally, we can get fixed we can change back.” Gina said.
“How? We don’t even know what caused this?”
“Well, maybe it was us getting too friendly with Duke.” Gina suggested. Allison sighed; she didn’t want to be reminded of that.
“Lots of people mess with animals, and this doesn’t happen.” Allison slapped her furry thigh. “At least I don’t think so.”
“Well, uh…” Gina groped for an explanation. “What about the pills Paige gave me? They’re pretty weird, maybe they could do this.”
“The pills?” Allison had forgotten about the strange green capsules. “Yeah! Those pills!” Allison stood up on her hooves. “That’s it! It’s those damn pills!”
