“Ohhhh…”

Starlight Glimmer rubbed her eyes and glanced over at her writhing girlfriend. “Trix, you okay?”

“I… I don’t… ahhhh…” Trixie began to pant softly.

As Starlight managed to focus in the dim light of the back of Trixie’s wagon, she found the blue mare running her hands over her small breasts, her hips, her sides… everywhere. It was like she was in heat or something!

“Trix, uh… I’m right here if you need some… relief?” Starlight offered, blushing at Trixie’s surprisingly lewd display.

“Can’t stop…” Trixie moaned. “Coming… it’s coming through… through my… horn…”

Starlight looked up at Trixie’s horn to find it glowing. The catch was, it was glowing the wrong color. Instead of a light pink, it was a bright, almost neon pink, with twists of red and purple in there.

“Okay, that’s… that’s weird.”

Starlight gritted her teeth and lit up her own magic to block the spell, only to have Trixie suddenly grab her hand. Starlight stared down at the hand. It felt… odd. Trixie’s fur felt sleeker and the flesh beneath seemed almost pliable.

“Don’t,” Trixie whispered, pleading with her. “I… I need it…”

“Trix, I don’t know what’s going on but—”

In a flash, Trixie sat bolt upright and planted a kiss firmly on Starlight’s lips. Starlight’s words died in her throat as the sheer need of the kiss overwhelmed her. In moments, she found herself responding eagerly, wrapping her naked girlfriend in her arms as they rubbed their breasts together in an increasingly heated makeout session.

Starlight lost track of time for a bit, but when Trixie pulled away, her face seemed to shine in the moonlight.

“Trixie… what’s… oh Celestia, your tits!”

Starlight gaped. Where once two cute breasts had sat, now a pair of tits the size of Pinkie Pie’s hung from Trixie’s slim frame. The nipples were thick and hard. They also dripped with some sort of fluid that wasn’t quite milk. Trixie shifted position and poked them, only to reveal they were incredibly springy… and as shiny as the rest of Trixie.

“What’s… going on, Trixie?” Starlight asked slowly, her eyes wandering over her girlfriend in a mix of lust and worry.

Trixie squealed softly and before Starlight’s eyes, the mare she’d fallen for transformed from cute to… mouthwateringly gorgeous. Her hips and ass swelled outward. Her legs slimmed down a little. Even her mane grew. It was as if she’d gotten a full head-to-toe sexual tune-up. Starlight… couldn’t really say she minded.

All the while, Trixie moaned and thrashed, working her breasts and spraying liquid across their bed and the rest of the wagon.

Some of it even landed on Starlight’s naked body. She shivered slightly as the strange sheen washed over the rest of Trixie’s body, leaving her with a strange look that…

Well, the only thing Starlight could think of was that Trixie looked like some sort of living sex doll. And to her surprise, that thought turned her on. A lot.

Trixie let out a whine, still shivering as the light around her horn brightened. Then, she started to mumble things Starlight couldn’t make out.

As she did so, Starlight reached out to touch one of the newly resized breasts. The moment she made contact, Trixie’s eyes flew open and she smiled. With a speed that shocked Starlight, Trixie had her pinned beneath her with her breast hanging before Starlight’s lips. Some of that milky fluid dripped into Starlight’s mouth and she shuddered.

“What… what’s happening, Trixie?”

Trixie lowered her breast to Starlight’s lips. Starlight couldn’t stop herself… she had to suckle. And as she did, an amazing heat washed over her. A need, a passion and a hunger for anything and everything Trixie.

“I… just got an upgrade to…” Trixie whispered quietly. “To something I’d… forgotten about. It’s okay though. Most of it’s completed now.”

Starlight managed to break away long enough to croak out, “Upgrade to… what?”

“Being a Dollmare,” Trixie replied. “Trixie was the first… but it looks like Twilight is now a much better version. For now.”

That didn’t explain much, but Starlight was starting to have a hard time caring anymore. She just wanted to suck Trixie’s nipples forever. Whatever her girlfriend leaked was fantastic!

Trixie grunted and let out another contented sigh. “Last part of the upgrade. A temporary part… to help you, babe!”

Starlight couldn’t pull herself away to ask what Trixie meant. It didn’t seem to matter all that much.

At least until she felt the sensation of a twitching dildo against her lower lips. Starlight gasped around the nipple and glanced down, only to realize that her girlfriend had grown some extra equipment.

“Don’t worry,” Trixie smiled as she began to slip it into her increasingly willing friend. “Once I cum in you, you can join the Bond and get all the upgrades I have!”

Starlight groaned as she pushed against Trixie’s strange cock, craving it more with every inch. It seemed to fill her up entirely, perfectly, fully… it seemed to take every bit of available space in her. Only then, did Trixie began to rock.

Finally, Trixie pulled her tits away, allowing Starlight to speak.

“Trixie… what’s happening?” she managed to whimper between her cries of pleasure. “I… I don’t understand.”

“You will,” Trixie whispered. “You will.”

Something inside Starlight told her to relax, trust Trixie, enjoy the cock and that all would be made clear soon.

As soon as she was just like Trixie.

So Starlight leaned back, spread her legs and let her girlfriend fuck her. Trixie grunted… and she began to climax. Something began to pour into her, something friendly that only wanted her to feel pleasure. Something helpful and wonderful and… something that made it hard to think. Did she really need to? She could trust the something…

It would give her all the answers she would ever need.

The something only had to make her just like Trixie. Starlight didn’t mind.

Trixie leaned down and kissed her.

“You’re going to love this.”

Starlight nodded. Of course she would.

She would love it.

Something inside her said so.
