Ellie Rubenstein pulled frustratedly down on the tank top she was wearing. Since none of her old husky clothes fit her twig-shaped body anymore, Ellie was wearing her sister Rachel's clothes. Unfortunately, Rachel was two years and a good deal shorter than Ellie. None of her clothes fit quite right. Ellie struggled to force the tank top to hide her scrawny belly.
"Hi there, sweetie!" Harper chirped as she arrived. "No that school's over, we can just hang out for a while. Trouble with your shirt?"
"You can say that again!" groaned Ellie. "It's actually Rachel's. I needed new clothes until I can get nice and chubby again, and you know how tiny Rachel is. Problem is, she's short as well as skinny. Look, her jeans don't even reach down all the way to my ankles!"
"Skyler thought you might be having that problem," said Harper. She whipped a shiny plastic rectangle out of her pocket. "That's why shi let me borrow hir credit card. You're getting a whole new wardrobe all on hir tab."
"Even though I intend to outgrow them in a few months?" asked Ellie.
"Skyler's freaking loaded," said Harper. "Shi really doesn't mind."
Ellie smiled and shook hir head. "Can you believe such a nice person used to act like such a bitch?"
"Blame hir mom," said Harper. "Now let's get going and buy you something that actually fits."
The two girls headed for a department store that Skyler Bentley frequented. One look at the name on that credit card (which was, ironically, no longer Skyler's actual name), and that shop would agree to anything. Ellie and Harper spent hours assembling the perfect wardrobe for Ellie's slimmed-down frame.
"Are you sure you want that sweater?" Harper asked skeptically. "It's so bulky."
Ellie smiled. "Exactly. It kinda disguises just how much fat I've lost. I bet I could look into a mirror in this and not entirely hate my reflection for once."
"Whatever works for you," said Harper. "Let's find a dressing room and see how you look in all this." They scooped up all the chosen clothing and headed for the dressing rooms in the back. Ellie tried on everything, loving how everything fit. Nothing hung limply as a reminder of list chub or pinched her painfully in places.
Just as Ellie was about to put Rachel's clothes back on, she paused. "You know, Harper... we're alone... and I'm in my underwear..." She grinned lewdly.
Harper laughed. "Why the hell not?"
"How about some roleplay?" Ellie suggested as she pulled off her bra and panties. "You can be a hiker who's lost in the woods at night, and I'll be the horny werehyena who finds you."
"Sounds fun," Harper grinned.
Ellie shifted, her thick body hair growing into dark yellow fur as her body expanded its height and muscle. A tail grew and feet became paws, and Ellie's breast ballooned and doubled in number. Her head reshaped into a hyena's before her clit began to change. The already oversized nub elongated into a glorious cock, and a hairy scrote blossomed below it while Ellie's pussy migrated backwards. Ellie grinned fiendishly as shi menacingly crept towards Harper hand towered over her.
Harper put on a convincing expression of terror. "Wh-what the hell are you?!"
Ellie laughed with pretend malice. "Guess."
"S-some kind of... werebeast?!" Harper gasped.
Ellie sniggered evilly. "Right first time. Smart for a human. What are you doing in my pack's woods?"
Harper pretended to whimper. "I... I w-was j-just... g-going f-for a... a h-h-hike! My n-name's Harper. Pl-pl-please, d-don't h-hurt me! I... I... I'll l-leave and n-n-never c-come b-b-back!"
Ellie laughed evilly. "Oh, I'm afraid I can't let you leave now that you know about my kind, Harper. I suppose I COULD eat you, but I'm feeling merciful." Shi lunged at Harper's prone body and began to tear off her clothes.
"WH-WHAT ARE YOU DOING?!!" Harper screamed in mock horror.
"I'm going to fucking make you one of us!" Ellie snarled savagely. Shi stripped Harper naked, pinned her down, and roughly rammed hir rock-hard cock into Harper's pussy. Harper screamed, but Ellie continued to thrust vigorously in her.
"Please, no! Stop!" Harper shrieked. "I don't wanna be a werehyena!"
Ellie flashed hir mouth full of gleaming fangs at Harper. "You should've fucking thought of that before coming into my pack's territory, bitch!" Shi hammered away at Harper's straining cunt. As shi pistoned hir dick back and forth, the werehyena used hir clawed hands to grope hir victim's perky tits.
"HELP, HELLLLLLLLP!!!" Harper wailed as her werehyena attacker brutally impaled her cunt with hir colossal dick. Soon that dick throbbed and exploded, spewing liters of werehyena cum into Harper's stretched snatch. Harper's vaginal walls clenched, and she shuddered as her own orgasm overtook her.
Ellie slowly pulled out of Harper, letting one last strand of cum splash onto Harper's toned belly. Shi stood up and stared down at hir victim. "Now the REAL fun begins!"
Harper held her arm up to her face in faux horror as light brown fur exploded from her skin. She screamed and groaned as her bones popped and cracked, pretending to find the transformation extremely painful. Her feet stretched out into paws and claws grew in. A furry tail shot from Harper's ass.
"Oh my God!" Harper gasped, screwing her face into a horrified expression.
Harper's boobs swelled, growing two full cup sizes. Harper felt them, trying to look shocked. Meanwhile, a second pair popped up beneath them, only slightly smaller than the top pair. Her face morphed into a hyena snout. Finally, her clitoris began to change. It slowly elongated, growing freakishly long. Harper grasped it, feeling the clit change shape in her hand. As her clit grew increasingly phallic, Harper's pussy pushed itself backwards and a giant ballsack grew where it had once been. Harper was a true herm!
Ellie grinned proudly. "What do you think of your new self, Harper?"
Harper smiled, hir hand still stroking hir new cock. "I... I'm beautiful. Thank you for doing this to me."
Ellie reached down and helped Harper up, hir face suddenly gentle. "Your welcome, Harper. My name's Ellie. Come on, I'll introduce you to my pack. I'm sure they'll all want to... 'get to know' you."
Harper broke character. "Damn, that was fun! You were so convincing, Ellie."
"I know!" laughed Ellie. "I actually fucking scared myself!" Shi shifted back into human form. "Always fun to get kinky with you, Harper. You look so cute when you pretend you're scared."
"You make it too easy with that dominant act of yours," Harper smiled as shi shifted back into human form and began pulling her clothes back on. "Well, let's go pay for your new wardrobe."
Once Ellie was fully dressed, the two girls headed for the cashier and showed her Skyler's credit card. Her eyes went wide at the sight of it. "You're friends of Stella Bentley? I'll just ring this right up."
"Actually," said a familiar voice, "It's Skyler now, I identify as non-binary these days."
"Oh hi, Ste... Skyler!" the cashier waved. "I love the new hair! Oh, you're really looking buff these days. Have you been working out?"
"You could say that," Skyler smiled. "Oh, if you're asking, my pronouns are shi/hir." Shi turned to Ellie and Harper. "Hi! I see you're making good use of the card I loaned you. Can't have you looking like a hobo, Ellie."
"Thanks, Skyler," said Ellie, "but I'd really rather just be able to fit into my old clothes again. God, I miss my big, squishy belly!"
"Don't worry, Ellie," said Skyler said. "Morgana and Kyūri Sensei are going to make some calls and get the state government to set up the student exchange program with Japan. Personally, I'm pretty stoked to meet some yokai."
"And I'm stoked to see Japan with Ellie," said Harper.
"And I'm stoked about getting my body back to its jiggly normal," said Ellie. "I sure hope Morgana and that kappa sumo guy work fast."
