Filly Starlight Glimmer learns the hard way that you shouldn't trust random shopkeepers offering you a deal...

A young Starlight first embarked to search for Sunburst a couple of days ago. She knew he'd gone off to that magic school thingy, but she wanted to see him at least one more time. As any filly would, though, she became sidetracked by toys. Maybe a souvenir would help cushion the pain she felt from losing her friend.

Unfortunately for her, the shop owner intends on adding a toy to his collection instead...

Back and Forth...

“But…but I only have 10 bits…”

Starlight Glimmer was a big filly, a whole nine years old. Nine! But even considering that, she had trouble stopping her voice from wavering as she stared down at the checkered floor, her vision wobbly with tears. Not only had she come all the way to Canterlot looking for Sunburst and eventually ended up empty-hooved, but now she found that even her allowance couldn’t buy a single dumb toy in this ‘premium’ toy store, whatever that meant.

“Hey, shhh, calm down little one…” The bearded stallion in front of her seemed at least partially concerned, which was good…maybe. “I know everything is expensive, but that’s just Canterlot. But…tell you what.” His eyes twinkled as he leaned in closer, and gave her a big wink. “I can make you a deal.”

“Really?” She tried her best not to sound too excited, but the butterflies and fireworks in her stomach were too big to contain entirely. “I mean…uhm…could you?”

“Yeah, if you promise not to cry, I can. You look like you’ve had a rough day.” As he smiled gently, she took a moment to wipe an almost-tear away from her cheek, and peeked up at the stallion. He rewarded her with an even wider grin that made her feel fuzzy and warm.

“Alright.” He leaned back with another wink, using his magic to float over what looked like…a gem? That was a weird toy. It was a cool bright green though, very shiny, and had so many faces; she could see herself in it many times over when he floated it closer! There was even a string attached to it too, maybe she was supposed to swing it around or something.

“This is what I’ll do,” the shop-stallion continued. “I’ll take your ten bits, for being such a cute filly, and then let you pick any toy you want. All you have to do is watch this crystal closely…and listen to my voice. How’s that sound?”

“Wait, what?” She was going to protest, but the stallion was already using the string to set the gem in motion, back and forth, ever so slowly. She looked at him in confusion, and his smile faded just a bit.

“Look at the crystal, not me,” he said. “Focus.”

She did so. The crystal let out a soft green glow as it swung. She looked up at the shopkeeper again, but found that her eyes swung back to the gem automatically. It was spinning, fluttering, and flashing with images that she couldn’t quite make out from the reflection on the surface. She just couldn’t look away. It was so deep, and shiny, and mesmerizing…

“Good filly.”

The words seemed to echo in the space between them and all at once, the tension in her mind faded, leaving her feeling very…Numb. Her mind was fuzzy, but there was still enough clarity to note that she was very happily looking at the weird green thing the shopkeeper was holding, in total silence. She felt her tail swish behind her as she looked at it, back and forth; back and forth. She found herself turning to look at the stallion, then back at the crystal. The crystal was so pretty. She had to look at it. Otherwise she wouldn’t get her toy. Plus, it was so…deep…

“Feels good, doesn’t it?” His voice had moved closer, almost like he was standing next to her. She couldn’t even tell anymore if he had moved; all she saw was the crystal and its sparkly depths. She had to look closely at the crystal to make sure it was even still moving as it floated a bit closer, still dangling from the string. A chill ran down her spine: yes, it did feel good.

“Feels…good…” She wasn’t sure if she was the one saying it now, the voice almost felt alien to her. She was just so very happy in that crystal’s grasp. She could only focus on the crystal. It was like it was the only thing in the world that mattered.

“…Good…” she whispered, staring down at the swirling sparkles. “….Feels…”

“Good.” The voice completed her thought for her, topping it off with a warm chuckle. “And you’re a good filly. Do you know what good fillies do, though?”

“N-no?” It was hard to focus, but she did her best to stare at the glowing…thing. What was it called again…? Not that it mattered. It was pretty.

“They obey.”

Starlight shuddered as the green glow seemed to brighten in time with the word, hammering her poor little mind into submission. Her mind raced as the words thundered into her mind again:

“And you are a good filly…so long as you obey.”

She was a good filly! She had to obey. She looked at the green gem again. It looked so very pretty. So pretty. She had to obey. But what was she doing exactly…?

“Do you want to obey?”

“Y-yes…” It was hard to think. Her head felt so heavy and fuzzy. She might have been drooling, but that didn’t feel important. She just wanted to stare at the deep sparkly gem.

“Then drop for me. Even deeper into your cute little trance.” The voice laughed, and she could almost hear the glow intensify, so she tried.

“…Deeper…” she said, letting her eyes droop more and more as she stared just a touch more intently at the crystal. It made her happy. She liked looking at it. She wanted that gem. She wanted to please that gem and the voice attached to it. All she wanted was that gem, and to make it feel good.

“Good filly.”

Her whole body shook with pleasure as his praise warmed her. Her eyes were almost drooping shut at this point, but she managed to keep them open. She was a good filly, but she could be a better one! She had to be as good as she possibly could. She would make her owner…make him happy. She would be the best filly in the whole world, so long as she could keep looking at the crystal.

“Now…stay very still, good filly. I’m going to get some things and then you will become my toy. How does that sound?”

“It s-sounds…good…” She tried to keep her voice from shaking, but she couldn’t hide her ecstatic smile as she stared at the shifting, shining gem. She couldn’t even begin to think of what a “toy” was in this instance, but she knew that she wanted to be one, whatever he was talking about.

“Good.” The voice slipped into her thoughts, teasing her brain as she felt something wrap around her horn. The string. She really wanted to obey. The words chilled her, deepening the command until she was left staring straight ahead, at the gem again. It was no longer swinging, but somehow… more enticing than ever. Closer, bigger, deeper…warmer…

“Good filly.”

She could feel herself shake even more as an incomprehensible bliss washed over her. She was just so happy to obey. Her eyes were on the stone so intently that shining stars seemed to flare up at the corners of her eyes. Celestia herself could have appeared before her and she wouldn’t have noticed. All she wanted…all she wanted…was the gem.

“All done here,” the voice said softly. “Now, get up and follow me to your new room. You will be so very happy there.”

She hadn’t even realized she’d sat down, but now she slowly stood up, staring happily at her new gem. She wanted to play with it. She wanted to make it feel happy. She just wanted to look at it again, to see it go back and forth. Back and forth.

“Now, now. Stop drooling on the floor.” The voice sounded amused as she closed her mouth, looking up to the stallion again. She could see him, but only distantly, filtered through layers and layers of endless green reflections.

“Good filly. Now come.”

She followed. Walking was a bit of a stretch, but she felt herself moving in response to his will. It was hard, but she could manage, and she didn’t have to think about it! That was nice, letting someone else tell her what to do. It was so nice to know that someone would do that for her. She just wondered what was next . She wanted to keep following, to please this wonderful owner. He would make her into a toy, and then she could have fun with the crystal all the time!

“Are you allergic to anything, my good little filly?”

“N-no…” Starlight moaned, flushing warmer than ever as the words of praise took nasty little twists about her mind even in such innocent questions. She didn’t care; all she wanted was to be a good little filly and have fun as his new toy. Everything else could wait, she told herself, the owner knew what was best for her.

“Excellent. Then you’ll make a great addition to my window. Stand here.”

She did as she was told, as good fillies did, spreading her balance widely when requested. She felt the newly-wooden floor beneath her wobble a bit, but her eyes stayed locked on her gem. It shimmered so brightly, and it felt like it was glowing right through her.

“Stay still, and balance if you need to. Otherwise, just be a good girl, sink deeper, and obey for me, okay?”

“O-okaaaay…”

She felt other things happening soon. Something stretchy and tight was pulled up over all of her legs and locked in place with straps around her upper body. It felt cold at first, but quickly became warm, and helped hold her securely to the now-mobile floor beneath her, moving back and forth. She didn’t seem to be able to move her legs at all when she weakly tried, but that was all unnecessary anyway; the green gem was right there. It was beautiful, and so all she wanted was to make it feel happy.

Then something else was tightened around her belly; also cold at first, but stretchy and squeaky, and warm as seconds passed. It felt nice. She even heard the voice mutter something about ‘latex’. So that’s what this was. If wearing it made her feel good, she was glad that she could wear it, because she loved it.

“Good girl,” the voice cooed from miles away. She felt herself squirm slightly, shaking. She somehow felt even better as a collar closed around her neck, and was locked in place with a gentle click. “Open your mouth wide.”

Starlight did so without question, panting as her body glowed hotly with pleasure. She felt something rubbery and hard slide between her teeth, before a bunch of straps tightened and locked the thing there. Her tongue felt funny being pinned to the bottom of her mouth, but that didn’t matter. As long as she could still feel the crystal deep in her mind…

Next something gripped her horn tight and didn’t seem to let go. She could feel her inner magic shrink and disappear, but that was no big deal. She blinked as she became unable to look down, but all she wanted to do was make the pretty crystal happy.

“Everything okay?”

“Mphanmh,” she muttered, drooling as she felt some sort of stiff wrapping slide onto her tail, holding it perkily upright. Something slid into the tight stuff around her legs, and then something small slid into her special place, which was oddly wet. It took a second to realize, too, that it wasn’t just wet for no reason…she could feel master’s tongue in there too.

“Now rock for me. Back and forth.”

Starlight did what a good filly would do and obeyed. As soon as she squeaked forward against the latex clinging to her legs and the base beneath her, she felt something begin buzzing down there, filling her with even more pleasure than she’d ever imagined. The more she rocked, the faster the buzzing got, and the better she felt with every passing vibration and fleeting contact with her owner’s tongue. She squealed, drooling more as her hips unconsciously thrust forward, sending her tilting forward and then rocking back, in a never-ending feedback loop of feeling better and better.

“That’s my good little filly. Relax, go deeper, feel good…be my rocking horse.”

Starlight’s mind almost shattered from all the pleasure erupting from her insides. She moaned as she rocked and rocked and rocked, teeth clamping on the rubbery bit in her mouth, her mind shutting down from all the feelings flooding through her. Deep within her mind, the gem flared brightly and seemed to change from green to a green beyond green…especially as her movements made it start swinging again.

“Fillies are supposed to purr when they’re comfortable and happy, aren’t they? I wonder if you can do that for me. I want to hear it.”

Starlight needed to be a good girl. She could do it, she could do anything to be as happy as possible. Rocking was the happy thing to do, along with following her owner’s commands.

She moaned in what she hoped was the right way, voice high and squeaky as she sagged with pleasure. Her eyes rolled over white as her chin pressed against the bit in her mouth, eyelashes clashing together as she looked ahead. It made her feel so good, so happy, to obey her owner. He would have so many other things for her to do, too…

“That’s really good! I think you’re ready to go in the window. What do you say? Maybe I’ll even sell you to some other lucky pony~”

Starlight beamed as wide as her gagged mouth would allow. She wanted to be a good toy for her owner.

“Say thank you, sweetie.”

“Thatth ooouth, mahfher…!” Her entire body exploded in bliss as she squealed, eyes rolling back to normal, or almost so. Her tongue had disappeared inside her mouth, she noted distantly. She felt her legs, which should have been at least cold since she hadn’t been moving them, were even hotter than before. She still felt super bouncy.

“What a nice present you’ll make. I’ll start posting flyers and see what I can do. But you just keep rocking. I’ll record my commands and play them for you, day and night, as you just keep rocking in my window. Sound good, my good filly?”

It did sound good. Starlight wriggled her hips a bit, feeling somewhat odd, but really good. She would make so many other ponies super happy by being a good girl for her owner.

“Excellent. Just one last thing to remember: good fillies don’t cum.”

She wasn’t sure what that meant, but she did hear the skittering of a chair sliding across the room. Through the corner of her emerald-occupied vision, she could see him sitting down behind her, and scooting closer. Something between his legs was standing straight up…what was it? Certainly not as interesting as the crystal, but…it crossed her mind just a little bit at least.

“Rock a bit further for me,” Master said, positioning himself as close as he could get. Starlight didn’t even think, just did; after all, that would feel better. Even though the good buzzy thing slid out of her bottom, she still felt so good just to be obeying. Further, faster, harder—

“Mmmph!”

Starlight whined as she felt something suddenly spread that wet place apart. The hot pleasure returned immediately, but when she rocked forward, the thing popped out, and she closed shut around nothing. Back, the thing went in even deeper, making her feel better. Despite the tiredness enveloping her mind, the filly felt her eyes widen as she realized the pleasure of obedience and this strange insertion was feeding back on itself.

“Naughty little girl…” her owner teased, placing a hoof on the top of her plot and pushing her down himself whenever she started her backswing. Starlight shivered from head to hoof as she felt that big thing filling her up more every time she rocked back, making her feel better and better, moaning and drooling more and more but not even caring. Who knew obedience could feel this good?

Things got faster, hotter, better. Even her owner was grunting now, panting, and so was she, liquid lava goodness splashing over her spine and filling her with delight beyond imagination. It just kept building and building with no end in sight…!

An end did come, sadly enough. Even though she was still focused on the endless, infinitely deep green facets in front of her, Starlight could feel a bunch of hot goo shoot inside her as her master finally tipped her back and held her there, moving the thingy back and forth just a little bit as the warmth increased. Sadly, the pleasure started to fade even as the fullness set in and she felt a bit more at rest. But master had thought of everything; shortly after the thingy slid out and left her tushy empty, she felt him pat her head, and whisper:

“Good filly.”

The buzzy thing slid back into her heiney and started buzzing again, making the little filly squirm and thrust as the uncapped desire began to build once more, driven both by his words and the buzzy thing itself. The last thing Starlight heard was some sort of magic twinkling, and then one final command, one final thing she could do to please her owner:

“Don’t think.”

And then there was bliss.
