"You know," mused Gabby, "I'm starting to feel a bit left out of the animal-girl club...but..."
Gabby untangled herself from the other two girls, getting up and heading for the door of her small room.
"Where are you going?" Amy and Lina asked in unison.
"I'll be right back, just had an idea." Gabby said over her shoulder, as she disappeared out the door and was gone, leaving the catgirl and ponygirl to their own devices.
"Should we, you know, go with her?" Amy asked.
"I'm too exhausted to move." answered Lina.
"Oh?" asked Amy, arching an eyebrow, "then you wouldn't be able to do much if I did this?" and she leaned into her friend and kissed her again, paws roaming down the sleek shiny mare's body, stopping briefly to tease her breasts, then teats, then finally moving down to caress her friends new balls, gently squeezing to elicit a squeak from the ponygirl.
At that moment, Gabby came back in, holding a pair of flasks filled with some liquid.
The flasks each held a liquid of a different color, one a rich scarlet, and one a deep blue. The blue liquid seemed to be fizzy, a bit like lightly carbonated water. The red was thicker, almost like olive oil. Both flasks were sealed with a cork, rather stereotypical, if these were potions sold by this store.
"What are those?" Lina asked.
Gabby smirked, and with a wink replied "You'll see."
She placed the blue flask down on the side-table, and uncorked the red one. She looked at the two animal-girls, seeming like she was trying to decide something, nodded, and exhaled, then up-ended the flask, gulping down its contents.
She licked the last drops of the liquid from the mouth of the flask and from her own black lips, then placed the empty flask beside its twin.
Her stomach made a small gurgling sound, and then Amy and Lina saw a change begin. Gabby's already slightly curvy frame began to fill out more, her breasts and hips increasing in size, giving her a full figure. Her ears began to grow, changing into triangular shapes and increasing in size, eventually folding over themselves and her nose began to turn up. Her canine teeth began to grow too, as her face pushed out into a snout. She brought her hands up to feel these changes as they were happening, only to notice that they too were changing. As she watched, her index and middle fingers began to merge, as did her ring and pinky fingers. Her thumbs increased in size, until her hands were adorned with three stubby fingers.
Her feet underwent a similar change, but instead of three, her toes merged into two digits, then further into a pair of cloven hooves, or trotters. Gabby almost lost her balance when her legs shifted in shape, stretching and re-arranging to resemble hindquarters. A tail began to poke out above the black latex covered girl's butt, quickly growing thick and curling around in a spiral.
Gabby was breathing hard, but making pleased sounds, when Amy and Lina notices bumps forming on Gabby's stomach and abdomen. They watched as these bumps formed into nipples and breasts followed soon after, the girls watching as three additional rows filled in below her original pair of mammaries, the nipples thickening into small teats. Finally, they watched as Gabby's black latex skin started to lighten, leaving her a dusky rose or pink color.
"A pig?" Amy asked, wide eyed.
"Not quite what I was expecting, but I like it," Gabby mused, sliding her tri-fingered hands up her eight breasts, "besides, I think pigs can be cute. And I have one more surprise in mind for you."
She picked up the blue flask and uncorked it, draining the liquid, then she gave a light burp and scrunched up her face.
"It tickled my nose," she explained.
She began to stroke her hips and thighs, sighing as the potion took effect.
A lump formed above her pussy, slowly increasing in size until the top opened and a growing spiral boar's cock began to slip free. Underneath this, a sack developed, filling with testicles that grew in size from grapes, to eggs, to kiwis, hanging firm in Gabby's new scrotum.
Gabby began to stroke her new appendage, and slid down to cup her new balls, then slid her hand even further back and opened her mouth in a silent gasp as she slid her thickened finger into her sex.
"Oh, good," she breathed, "all the original equipment is still there."
Gabby crawled onto the bed and turned to face the other two girls, spreading her legs and reclining on her elbows.
"That's it," she cooed, as Amy and Lina snuggled up to her, exploring her new body with their hands and lips and mouths, "come to mama."
Gabby moaned and sighed as her teats were licked and pinched, massaged and fondled. She groaned as she felt a large cock, Lina's, pressing against her vaginal lips, and gasped as she felt Amy's new member pressing against her rear opening.
Amy reached her rubber paw down between Gabby's legs, and began to stroke her spiraling phallus.
Gabby hooked a leg around Lina's, turning into the pony-girl, as Amy wrapped her own arms around the pig-girl. She arched her back as she came, her vagina clamping down on Lina's large member, while at the same time, her new balls clenched, sending her seed spurting out between her breasts and the horse-girl's.
Amy climaxed as well, shooting her load deep into the pig-girl's ass.
With wet, sloppy sounds, the girls untwined themselves and laid there, cuddling on the latex bed.
