"...horse!" Kyle said confidently.
"Really, dweeb? That's all you could think up?"
"Not all, no. For starters, not only will your limbs change into those of a horse, but your ass and genitals too—a shire stallion's, to be precise. You do know what a shire horse is, right, Jenny?"
"Why would I, nerd?"
"Well, they're the largest breed of horse on Earth. Better get watching your weight, haha!"
Jen tried to hang up, disgusted by what Kyle was telling her; she found she could not move the phone from her ear, however.
"Why can't I hang up? The fuck is going on?" she said, panic rising in her voice.
"I'm not done yet, that's why. To continue, for your dare, you'll forget you've been cursed for a week. You'll think of your changed body as normal. After that week is up, it won't be me who you think used the curse on you, no. It'll be your precious cheer squad! And to seek revenge, you will curse each of them one by one with more horrifying changes than the last, until each of them is transformed! You'll never even suspect it was me!"
*CLICK*
"Wh-what the fuck?" Jen screamed into her phone, hearing it fall to the floor as her limbs froze. Jen began to cry as she felt her bones painfully shift, her body falling to all fours. Pain erupted from her hands and feet as they began to stretch longer and longer. She felt her fingers merge together, two of them disappearing and the others thin out as her middle fingers and toes stretched longer and longer, the nails expanding to cover her whole fingertips. Her thighs also began to shrink, becoming flush with her body, giving her the horizontal posture of a horse. Soon she screamed as her limbs began to grow larger and larger, soon hoisting her higher than she used to be standing upright. She felt a twinge at the base of her spine, a long tail growing in, and a slight push as her vagina pushed out to become the sheathed cock of a stallion. Her limbs and ass itched profusely for a moment, and as soon as it began, it was over. New sensations flowed into Jen's brain as she regained control of her body.
Jen looked over at the mirror and screamed. She looked at her reflection, her athletic body now supported by the arms, legs, and ass of a shire horse stallion! She looked at her speckled grey coat, her black tail swishing behind her. She took a few tentative steps, immediately noticing how she felt like she was walking on her tip-toes. She also felt how immense her weight now was, hundreds of pounds of equine muscle making up her shoulders, hips, and limbs. Soon, however, a feeling of peace washed over her, eliminating her panic. She saw herself in the mirror, her huge butt, legs, and arms, and saw it as normal, how she had always been. She also felt her new balls flop freely as she walked around, completely unaware that they had been any different even moments ago. Jen heard her mom call out that breakfast was ready, so she decided to walk downstairs, feeling her ass brush against the doorframe as she exited. She relished in her deep clops resonating off of the hardwood floors as she made her way to the kitchen, slipping slightly due to lack of purchase.
"How's my little cheval doing this morning?" her mom greeted her, carrying a large bowl of oatmeal.
