"I say we all go next," Ellie said, wiping the arousal-induced sweat from her brow.
"Trust me, girls," Beck grinned, playfully sliding hir foreskin on and off of hir cock's glans, "You'll love it!"
Ellie, Harper, Brianna, Kristi, and Joelle all swallowed the tangy contents of their vials at once. Soon, they felt an intense heat burning through their groins, demanding that they lavish some attention on their aching pussies. As they masturbated, they felt their clits swelling and reshaping into penises, just as Beck did. Before long, all their slits migrated backwards and their new ballsacks dropped, signalling that they were now true herms, even as humans.
Suddenly, each dickgirl blasted cum from hir tip. Ellie screamed in pleasure as shi shot out a rope of cum that landed on Brianna's thigh, only for Harper to splatter jizz all over hir own tits. Once the exchange students were fully spent, the floor was coated with a thick layer of futanari spooge.
Joelle approached Kristi, walking slowly to avoid slipping on the cum-slick floor. "Look at my new dick, Kristi!" Shi held it up by its long foreskin. "Isn't it amazing?"
Kristi took hir girlfriend's new pecker in hir hand. "It sure is a beauty. I like the foreskin. I've noticed they all come that way."
"Makes sense," Joelle giggled. "Nobody's born circumcised, after all. If any of us wanna be cut, we'll just have to have it done."
"It sure doesn't look like anyone here wants that," Kristi remarked, watching the other girls appreciatively checking out their freshly grown cocks.
"Yeah, I love my cock just the way it is," Joelle said.
"Even if it's littler than mine?" Kristi teased.
"Yeah, it's cute like that," Joelle said. "Especially considering that you'll be bigger than me in every possible way once you can get your hands on the chankonabe they make here. You'll be a big, fat kitsune, and I'll be a skinny, little kawauso."
"I can't wait to take a selfie of us once that happens," Kristi smiled, lovingly stroking Joelle's cock to erection as shi spoke. "Hey, now that you've got a real cock, do you mind if I suck it?"
"Be my guest," Joelle smiled lustfully. "I am more than ready for my second jizzing!"
Kristi took Joelle's little dick into hir mouth and licked at it. At the same time, shi raised a hand to fondle Joelle's balls. Joelle may not have had the biggest cock in the world, but hir ballsack was very long and dangly, and Kristi enjoyed having it to play with as shi sucked hir mate off. Out of the corner of hir eye, the werefox could see the other exchange students beginning to explore each other's penises, and shi even noticed that some of the yokai were joining in. Beck was moaning lewdly as Brianna and Yoshino double-teamed hir while Harper gleefully ass-fucked Ellie next to hir. The horniness of the transformation obviously lasted a while.
As shi poked hir nimble tongue inside the nozzle of Joelle's long foreskin, Kristi shifted into hir vixen form. Brilliant red-and-white fur blossomed all over hir body, and a bushy tail sprouted just above hir round ass. Hir feet became paws, hir tits swelled, and hir face elongated into a vulpine muzzle while hir ears came to points and moved atop hir furry head. Shi could actually feel hir tongue morph as shi rubbed it over Joelle's throbbing shaft, earning a lustful moan from the human. Lastly, Kristi's own cock shifted into a more canine shape, complete with an inflatable knot. All around hir, shi could see similar transformations as hir werehyena friends assumed their bestial forms to better fit in with their new yokai classmates. Kristi wondered if Joelle felt a little out of place, being the only human in the room.
Joelle couldn't feel out of place, however. Hir mind was much too busy with pleasure as hir mate's vulpine tongue brought the human girl to the brink of orgasm. Before long, shi was pushed over the edge. As pleasure spread from hir burning loins to cloud hir mind, Joelle's cock began to throb more violently than ever before it started shooting high-pressure jets of cum down Kristi's throat. Kristi tried not to gag as the salty cum plastered the back of hir throat. What Joelle's dick lacked in size, it made up for in sheer, raw power!
"Eh, sorry 'bout that, Kristi," Joelle chuckled once hir jets of seman finally slowed to a trickle. "I guess my dick doesn't know its own strength."
"At least it has some stamina!" Kijo laughed as shi stroked Ellie's cock to ejaculation. "My prissy little dick always cums in less than a minute. If you could teach me how to hold it in, I'd be really grateful!"
"We'll see what we can do," Joelle said, fondling hir own cock, still in disbelief that shi had one.
"Well, we did it, girls!" Ellie declared, triumphantly pumping hir fist in the air. "We're full, 24/7 herms now, and that means we qualify to attend this sumo heya!"
"Not quite," Saku said. "One of you still has some necessary transforming to do, and hir mate wanted to be a kitsune for the fun of it, I believe."
"That's right," Joelle nodded. "I can't stay here if I stay human, and Kristi had hir heart set on being a kitsune."
"Then we'd better proceed immediately," Saku said, reaching into her bag of witchly supplies.
