“Fuck it,” Delilah clopped forward on her already partially transformed hooves. “You’re right. Give me some cum. Let’s do this!”
“Mmm,” Taylor moaned. “That’s the spirit, honey.”
The anthro mare uncapped the jar again and Delilah closed her eyes as the scent of it hit her. It did smell very very good…
“Hit me,” Delilah whispered.
Taylor held up the jar to the black mare’s lips and the horse took a deep breath. She slipped out the tip of her tongue and lapped sone of the cum up, drizzling her tongue and drawing it back into her mouth. She swallowed deeply and let out a gasp.
“It tingles!” The mare began to tremble. “Oh god, I’m tingling all over!”
Taylor’s breathing quickened as she recalled her own transformation and took a few steps back, putting the lid back on the jar and clutching it close.
Delilah’s hooves went first. They were already a little changed as a result of her previous intake, and the ingestion seemed to concentrate on those first. She pitched forward and whimpered, front legs quivering as the joints snapped and her fingers started to splinter from her hooves. Suddenly, her front ‘elbows’ inverted with a sickening crunch, nearly causing her to collapse as her weight suddenly shifted.
Her body was shrinking. Losing length, thickness, trimming down. Her belly shrank in flat, her back hips began cracking.
Taylor circled, eyes wide with with amazement, very much enjoying the sight of the transforming horse and watching every little subtle shift and change. As she got to the mare’s rump, the scent hit her in full and she gasped. The other horse was heavily aroused and dripping from her slit.
Delilah managed a whimper as she glanced back and began panting. “This feels so goooood,” she whined.
Taylor knelt next to the mare and began stroking her back. Her back legs snapped into shape much like her front. The shape began to elongate even as her arms grew up front and her new fingers solidified. The black mare was in quite a strange state, halfway between horse and horse woman. She rolled onto her back, legs splayed, arms held tight as her shoulders popped them into place across a tight torso.
“So good!” Delilah cried, gasping. Her tail swished under a tightening ass as her torso continued to turn humanoid. She was already so muscular, and that definition was tightening and growing.
Taylor watched in awe as two lumps began to form on Delilah’s chest and her equine teats shrank away.
“Auuuuugh!” Delilah squirmed, her black pussy lips quivering as breasts began to grow. Big heavy breasts, far more expansive than Taylor’s from the look of it. “Oh god! Oh god, I’m gonna… gonna…”
Taylor gasped as the black mare shuddered and threw her head back, a hot orgasm firing through her body and curling her hooves. She began to grow. She was already so big, but she was getting even bigger. Taylor watched with awe as the black furred horse woman grew in more feminine, with big biceps, powerful thighs, and two big soft breasts steadily pumping up on her chest, the pert pink nipples visible through her fur.
Taylor was about seven feet tall. Delilah was going to wind up much bigger. Did her natural horse genetics somehow dictate her growth? Increase her reaction to the changes? Taylor found the idea fascinating.
“F-Fuck!” Delilah whimpered, tossing her head back a second time and biting her lip. Taylor gasped as the growing horse woman let a hot trickle of her juices out, dripping from her slit and forming a small pool on the floor of the stable.
Now mostly complete, the black horse was growing in every direction. Far surpassing Taylor’s size and strength, Delilah gasped as she crunched and popped and swelled, reaching nearly nine athletic feet tall before a final jolt signalled the stop of her incredible transformation.
The black horse woman stared up at the roof of the stable, gasping and trembling. Taylor knelt down and with wide aroused eyes she reached for Delilah’s hand, the other beefier horse woman taking it and squeezing gently.
“I’m so big…” Delilah glanced down, her muzzle nearly pressing into two massive firm breasts, each bigger than a man’s head.
“Girl, you’re fucking huge!” Taylor laughed, seeing how muscular and athletic the new horse woman was. Delilah was now pound for pound a perfectly developed athlete, her triangular upper body slimming down around her waist only to fill out again with powerful runner’s thighs and big bulging legs.
“Fuck, I am, aren’t I?” Delilah gaped, sitting up and running a hand over her huge arms and ripped frame. “I’m still undeniably feminine though…”
“Yeah, not too big…”
“Mmmm,” Delilah nodded, glancing at Taylor with a smirk. “You look so small compared to me. I kind of like this.”
Yeah, me too, Taylor thought with intense arousal. Wonder what would happen to you if you took more…
