Twilight and Chrysalis sat in the library by the fire, reading the spell Twilight had summoned her workerfriend to discuss. Chrysalis ran her tongue over her fangs as she looked over the description of the spell, and the brief synopsis of the effects it would have.

“Are you sure you’ll be alright, Twily?” the changeling asked, doing little to mask the concern in her tone. The Alicorn smiled assuringly.

“Absolutely. It’s only a tier three transformation spell. Besides, what better way is there to learn about a new species than to become the creature you’re studying?” Twilight beamed as she gazed over the page again, her hoof tracing the tail of the lamia on the page. “Lamias are a rare sight in Equestria. And nopony would ever dare travel to the Badlands to study them. Especially Fluttershy.”

“To her credit, she is pretty justified to be terrified of the Badlands,” Chrysalis reasoned. “Why do you think I was so eager to move my hive here, to Equestria? Changelings may be, technically, a predator to ponies… but in the Badlands, our position on the food chain is dramatically different.” Twilight shuddered at the thought of wild Badland animals eating each other in cold blood, and tried not to dwell on that thought.

“Anyway… I’ve been wanting to try an impersonation spell for a while now but… well, not many ponies are willing enough to be in the same room as a creature like a lamia. Even if it is just one of their friends transformed into a temporary lamia.” Twilight pulled the cutest puppy-dog face she could muster. Chrysalis rolled her eyes at the display with a chuckle.

“Alright, alright,” the changeling conceded. “We’ll try out your special little spell.” Twilight let out a comical squee and wrapped her hooves around Chrysalis’ neck, nuzzling her affectionately.

“Oh, thank you, Chryssy. Thank you, thank you, thank you!” Chrysalis rolled her eyes with a chuckle at Twilight’s enthusiasm. Sharing a quick nuzzle, the changeling queen looked down at the spell in the book.

“So how does this work?” Twilight bounced to her hooves, eager to start casting.

“All I need to do is focus the spell on my own body and try to morph myself into a lamia. Then, once the transformation is over, we can start experimenting with my new body and abilities.” Chrysalis started looking a little less sure of herself as Twilight explained. “Relax, Chryssy. I’ll still be Twilight. I’ll be in complete control of what I do, and if I start getting a little too excited about it, I’ll cut the spell. You can trust me.” The Alicorn planted a kiss on her lover’s cheek, calming the changeling down. With a silent nod, the black mare signalled her partner she was ready to start the experiment.

Twilight closed her eyes and lit her horn. A soft magenta glow shrouded her body as she pictured the features of her desired new form. Her hind legs began to tingle as the spell began to mould her body into her desired shape. The flesh of her legs fused together, binding her legs into one singular limb. Her hips widened to support her new lower body shape, as her pony tail seemed to burn away like a sheet of tissue paper, her extended limb growing more and more into the shape of a serpentine tail. Instinctively, the snake tail coiled around itself, allowing Twilight to sit on top of its mass as she changed. The fur on her lower half fizzled away like boiling water, replacing itself with smooth, shiny scales.by the tie her transformation was finished, Twilight stood more than five feet tall, sat on her coils, while her tail itself was more like ten feet long. Chrysalis blinked in awe at the sight, a faint buzzing sound eliciting from her bug like wings as she took in her lover’s new form.

Twilight opened her eyes slowly as the glow from her horn dimmed to nothing. She shook her mane from your eyes and gave a soft smile to her workerfriend. 

“So… how do I look?” Chrysalis licked her lips unconsciously as she took in the elegant, serpentine body her love now sported.

“I wish I’d went out on the town more often when my hive was in the Badlands,” the changeling purred, giving Twilight a very sexy half-lidded stare. Twilight blushed and stuck her tongue out at her lover for teasing her.

“Yeah, well, you’re stuck with a pony for a lover, now.” She smirked, letting her eyes wander down to her hips to inspect her new body. “Wow. I have to admit, I didn’t really expect it to be so long.” Chrysalis snorted with laughter, falling onto her side and rolling around in roars of joy. Twilight blushed deep crimson and gently whipped her lover with the tip of her tail. “Oh, grow up,” she mumbled, embarrassedly. She looked at her scaly tail and shifted on where her haunches used to be. “Come here,” she beckoned, sweetly. Chrysalis calmed herself down, and sidled up to Twilight, sitting tantalisingly close to her coils. Twilight leaned back on her tail and allowed herself to slide down her coils, using her forehooves to drag herself across the floor. She wrapped herself loosely around Chyrsalis, encircling her a little with her scaly snake tail. “First test; how do I feel?” the Alicorn asked, innocently. The changeling nickered with a cheeky smirk. “Not like that,” Twilight whined, playfully booping her lover on the nose. “I’m just asking you to run your hoof over my scales and see what it feels like.” Chrysalis nodded once she’d settled down, and slowly ran a holey hoof across her sweetheart’s scales.

It was a rather pleasant texture. The scales were smooth, but you could feel the faint bumps and nooks where the scales linked like natural armour. She placed her other hoof on another part of the tail, and slowly caressed Twilight’s coils. Twilight’s breath hitched at the sensations that prickled her serpentine coils. Chrysalis smirked a little at the sound of Twilight’s gasp.

“Your scales feel warm to the touch, but it’s more like they’re room temperature, rather than irradiating heat themselves,” she commented, snuggling herself a little deeper into Twilight’s tail. The newly transformed lamia sighed happily as she closed her coils around her lover.

“You feel so warm, Chryssy,” she cooed, nuzzling her workerfriend affectionately. “I guess my tail must be cold blooded. It’d make sense, since lamias have snakes tails, so they must be cold blooded. Or, at least in their tails, they are.” Chrysalis softly peppered Twilight’s smooth scales with little butterfly kisses, making the lamia shiver a little at the feeling. The purple snake-pony closed her coiled tail around her lover slowly, settling them both in a very intimate cuddle. She dragged her torso along her tail to meet her eyes with Chrysalis’. “It says in my book that lamias are capable of hypnotising their prey,” she cooed. “Is it OK if I try that out on you, Chryssy?”

Chrysalis blinked in surprise at this request. Twilight had been rather secretive about the reasons for wanting to try this transformation out, but now she was beginning to see why. Not any ponies considered hypnotism a pleasant experience but Twilight, as Chrysalis helped her discover, found it quite invigorating. Finding out about a spell that allows her to be on the other end of the hypnosis? Of course the purple Alicorn would want to try it out. The changeling shook her head in amusement.

“Fill your horseshoes, my love,” she purred. Twilight let out an excitable squee and slowly wrapped her coils tighter around her workerfriend, securing her in a loving, if slightly tight, embrace. She looked her gaze onto her lovers and slowly willed her magic into her eyes, focusing on creating the psychic link needed to override Chryssy’s will.

“Look into my eyes,” she whispered, sultrily. “And let your mistress take control.”
