Jen was the first girl into the locker room that Friday, her cock tail swaying over her head. Kyle had given her the town curse on Monday morning. He'd expected it would take weeks for her to grow a full tail, but he'd underestimated how horny she was, especially with her pleasurable new appendage. Jen hadn't quit bullying people either, which Kyle had specified would also speed up the transformation. Thanks to their orgies, the rest of the cheerleading squad was rapidly growing their cock tails too, but none of them fucked or bullied as much as Jen.
As Jen was undressing, another another girl entered the locker room. Jen didn't pay any attention, assuming it was another cheerleader. Then the new arrival grabbed Jen and slammed her into a locker.
"How do you like your handiwork?" the girl asked.
Jen didn't recognize the face glaring at her. Then Jen glanced up and saw the girl had a scorpion tail almost as long as Jen's, but the end looked different, more like a... Jen gasped.
"Kyle?"
"Kylie, thanks to you."
Jen could believe what Kyle had turned into, or how quickly. "Did you get fucked by the entire football team?"
"No, just the three guys your dare forced me to. After that and some jerking off, my tail-pussy was long enough I could bend it around and fuck myself. Your transform wasn't very specific so self-pleasure counted. It's been a lot of fun, but now that I have this body, and especially these tits I had to come see you."
Jen began ripping Kyle's clothes off, and Kyle did likewise for what little Jen still had on. With their tiles, neither was comfortable being on their back or leaning against something so they moved to the bench between the lockers. Jen climbed onto Kylie's lap, letting the penis slide into her vagina. Then Jen's tail cock plunged into Kyle's tail vagina. The two began fondling each others breasts as they began their strange and erotic thrusting - each penetrating in one way but penetrated in another. Neither could hold back their moans of pleasure.
Kylie came first, his penis being little changed from before the curse. Kyle's climax caused his tail pussy to constrict, triggering Jen's tail cock to climax, followed by her normal orgasms.
In the afterglow, Kylie had on three words to Jen: "Transform or Dare?"
