Summer Vogel was hopping up and down like a hyperactive rabbit. "Me! Me! Pick me!"
Riley grinned. "I was hoping it'd be you. Now slip outta that uniform so we can get down to fucking."
Summer suddenly remembered that she was the last person in the gym wearing clothes. She glanced around the room at Abbie, Diana, and Chloe having a spit-roast, Selena ramming into Tatiana, Maddison and Sofia sixty-nining, Naomi and Jazmyn scissoring, Cassidy and Hailey giving each other handjobs, and Kadie thrusting into Layla's furry ass. The cheerleader suddenly felt very overdressed. She pulled off her uniform, which was quickly followed by her underwear, and walked up to Riley.
Riley looked over Summer's naked body. "Awesome. Now, where'd you like me to fuck you?"
Summer bent over. "In my pussy, duh!"
"You got it, babe!" said Riley. Shi aimed hir dick straight at Summer's vagina and plunged it in with all hir strength. Thanks to having taken Riley's entire strap-on collection in her pussy and ass over the years, Summer's pussy was just able to to take Riley's new werehyena cock somewhat comfortably. Riley reached under Summer and tweaked the cheerleader's navel piercing, eliciting a satisfying grunt of arousal from her.
The bliss built up as Riley thrust back and forth inside hir cheerleader mate. Summer groaned with approval as Riley pleasured her. Riley's arousal reached it's peak. "Oh fuck, oh fuck! SUMMMMERRRRRRRR!!!"
With that, Riley emptied hir massive load of transforming cum into Summer's waiting cunt. Shi pulled out and sat down to watch Summer transform, lightheaded and still tingling from hir orgasm.
As Summer rode out her own orgasm, she watched as sandy-colored hairs pushed out of her formerly smooth skin. Before she knew it, the cheerleader had a full fur coat and a mane. Much to her surprise, it appeared to have kept the rainbow highlights she'd dyed into her head hair as human; she wondered whether it was natural. Summer suddenly tensed as she felt her spine elongate and her muscles bulk up. Her legs and feet turned digitigrade and claws grew from her fingers and toes. A warm feeling over her ass told her that she now had a tail.
"How ya likin' this shit so far?" asked a smiling Riley.
"I'm starting to look beautiful!" gasped Summer, playing with a rainbow streak in her fur.
Summer watched transfixed as her E-cup tits ballooned to F-cups, and then G-cups, and then all the way to H-cups. While Summer tried to process this dramatic boob growth, a pair of D-cups sprouted just under her primary pair. Summer fondled all four fatty bags in delight; if any of this size boost carried over into her human form, she was going to be the most popular cheerleader on the squad!
"Look, Riley!" Summer chirped happily. "Check out my boobies! I've got four of these balloons now!"
"Can't fucking wait to play with 'em," said Riley. "Hot damn, I think yours grew even more than the others' did!"
Summer lifted a hand to her mouth as she felt her face change. First came her tongue, which lengthened and broadened as well as developing the little barbs that make a cat's tongue so rough. Summer felt her new tongue with her clawed fingers, happy to feel that her tongue piercing was still there. Her teeth sharpened, and her face pushed forward into a snout. Summer's ears then climbed to the top of her head, grew, and rounded, completing her head.
"Time for the main attraction!" Riley said excitedly. "Incoming dick!"
Summer stared at her pussy, seeing her clit begin to bloat. The nub then lengthened, stopping at around eleven inches. Its shape grew more and more phallic as a loose bag of skin grew beneath it. Two testicles then popped into the sack of skin, and Summer knew shi was now a true herm like the rest of the pack. Shi fondled hir new ballsack excitedly.
"Everybody, look!" Summer squealed with delight. "I DID IT!! I'M A WEREHYENA!!"
Selena pulled out of Tatiana. "Sorry to leave you hanging, Tats, but an alpha has a duty to greet new pack members."
"It's all good, Lena," Tatiana said as she watched her healing factor restore her torn and stretched pussy to good as new. "Just be sure to finish getting me off as soon as that's done."
Selena looked Summer Vogel over. The cheerleader was covered in sandy fur with brown spots and some utterly eye-catching rainbow streaks. Shi wasn't as bulky as Abbie, Riley, or even Sofia, but hir lean and wiry muscle was still very alluring. The real stars of the show, however, were Summer's four titanic, luscious boobs, all of them plump and firm as perfectly ripened fruits. A belly button ring glimmered through Summer's fur, and Selena could see jewelry in the new werehyena's tongue and ears as well. Summer Vogel truly was a majestic beast now.
"You look beautiful, Summer," Selena smiled warmly. "Welcome to my pack!"
"I'm so thrilled to be part of the pack!" Summer said, a huge grin on hir muzzle. "I can't wait to find my very own role in it."
Selena thought about that for a second. "You know, my old pack had a troupe of ritual dancers. They performed the sacred dances at the packs festivals. I bet you and the other cheerleaders would make great ritual dancers!"
"That's such a cool idea!" Summer cheered. "It's almost like what we already do for the school!"
"I'll plan it out with Ashlee," said Selena. "In the meantime, how about you take the Ring and transform someone?"
Summer nodded and took the Ring of Embraces from Riley's cock and slipped it onto hir own. She turned to the crowd of gleefully fucking humans and werebeasts (and one vampire), flashed a bright smile of pearly sharp teeth, and pumped hir fist excitedly. "Woohoo! Alllltiiiight, guys! My cock is primed and ready to make you into gorgeous slabs of werehyena muscle! Who wants to come up and take a ride on my big ol' schlong?!" Shi thrust hir hips, causing hir cock to waggle suggestively.
