When a colt hears that you can see things inside crystal ponies, who better to get some clarification about this than his crystal filly sister.

Crystal Step had heard that you could see things inside crystal pony girls, but he could never actually catch that happening no matter how hard he looked. Maybe he could ask his sister, Glass Slipper, if it was true or not. Little did he know just how true it was.

Yes. Yes they are.

It was something that I overheard my older brother say when he was hanging out with his friends. I could only hear a bit of it, but the idea stuck inside my head. There was the part about us being transparent; that was obvious. I could vaguely see everything if I looked through my own hoof. Then there was the part about girls that everyone took note of.

Apparently, if you put something inside them you could, “totally see it inside her,” as he claimed to his buddies. That was met with laughs, jokes, and a few not even believing him; calling him out and saying that there’s no way that he’d seen that.

I could hear him getting flustered and argue back, before finally bringing out his secret weapon: photos. I couldn’t see them, even if I dared to look through the crack in the door, but the room fell silent. I could hear them whispering and chuckling as quiet as they could, offering praise and congratulations this time instead. With the way my brother spoke back, I could practically hear him smiling from ear to ear as he shared more details that I couldn’t catch.

That happened a few weeks ago, when he was visiting us at home after studying abroad. He had gone back but that idea always kind of popped in my head at the weirdest of times: when I was sleeping, helping my mom cook, or even playing with my sister.

There was always a weird feeling in my gut whenever I thought about it, but I’d never follow up yet nor asked them directly. Though I did try to see it in action, however, no matter how hard I looked I couldn’t see it. I tried at the dinner table, watching my mom and sis closely enough that mom had asked me if something was wrong. I could feel my face heat up as I shook my head, embarrassed to be caught for some reason; I blamed it on thinking about how good the food was; she didn’t suspect a thing.

Though, like every other crystal pony, when we ate food, it just kind of disappeared down our throats, never to be seen again. That would be pretty weird if we could always see what everypony had eaten.

It was a question that had been nagging me for weeks. Now while my sister, Glass Slipper and I were in the basement playing an impromptu game of hide and go seek, I was thinking of it again.

“Found you, Crystal Step!” I could hear her yell out as she jumped into the room and stared right at me hiding behind a chair. “I can see your hooves sticking out!”

“Dang!” I said back in annoyance.

“You’re not being very good at this tonight. I’ve found you like every time,” she said again, rolling her eyes a bit. That was true, I had just been panicking every time I heard her count down super-fast and jumped behind the first thing I saw in the room. “Anyways, your turn!” she blurted out and the only thing I could see was her dark-teal coloured tail disappear past the door frame.

I covered my eyes and started to count down from thirty. The question had been distracting me the entire time we were down here. At first I wanted to ask mom to show me, but then I thought it might be easier asking Glass Slipper instead. She was almost a year older, but that didn’t matter much since we were in the same grade. However, as much as I would hate to admit it, she usually was the first to know more about stuff.

I had been wondering just how to say it to her without sounding like a dummy and have her rip on me like my brother’s friends had done. At least he had a picture to back up his claim, while I just had a crazy theory.

I paused for a second after forgetting what number I was on, but just shouted out loudly, “ready or not, here I come!” It felt like it had been long enough.

I headed out the door and began my search. I had hid in the last room down the hallway and I heard hoofsteps rushing away; she probably had a hiding spot already picked out before I started the count. I opened the broom closet and checked the easy hiding spots as I made my way down, but I was pretty sure she would be in the large storage room that we had down here.

Most of the basement was littered with boxes filled to the brim, stacked as high as you could go. There were paintings and lamps, chairs and tables, fans and a few old mattresses lazily tossed onto the piles of storage; even a few giant stuffed animals were hiding around down here.

There was enough clutter and junk in here to hide for ages, even with the lights on. I gave a quick survey, but couldn’t see anything obvious. I had a feeling that she’d probably hid inside the small, maze-like tunnels and passageways we had built throughout the room. I got onto my belly and started crawling along through one of the many entrances we had.

The light was a lot lower, being blocked by boxes and having a few blankets draped over everything as well, but I could see and feel my way around well enough. I tried to move as silently as a cat, listening around for any sound of movement or breathing.

I couldn’t hear a thing but kept moving along, going around corners and up and over the boxes that we couldn’t easily move out of the way; not for the lack of trying. I almost thought she wasn’t going to be in here.

Ahead, there was a bent mattress and sticking out from it I could see that dark-teal tail! “Yes!” I whispered to myself as I slowly approached. I was lucky. She usually didn’t make mistakes like this so easily, but I guess with the time it took me to get in here it probably took her nearly the same amount, and she had to be quiet.

Right when I was close enough I finally pounced, running and jumping high into the air and coming down right where the lump on the mattress was. “Fooound you!” I yelled out, feeling something squish underneath me as I landed and heard a loud, complaining groan from underneath as she scrambled to her hooves and out from the entrapping bed.

I flopped onto my back, giggling as she composed herself from the surprise. She swatted at my hindlegs but I just kicked back at her.”Haha, who was easy to find this time!” I said with a small smirk.

She swatted at me again as she started to giggle. “You still are!”

I rolled my eyes and finally sat up after the barrage of flying hooves had settled down. We had probably been playing this for an hour, so it was no surprise that she flopped down on here as well to take a small break in between.

Which gave me time to think about that silly question still floating in my head. This was the perfect time to ask it too, it was just me and her in the basement; nopony ever comes down here besides us. I stared at the ground and could feel my heart start to beat faster for some reason, like I was asking her something I shouldn’t… but I needed to know!

“U-uhh… Glass Slipper…” I started to say and she looked up at me curiously. My face turned red, knowing that I already crossed into the point of no return. I could feel the words getting stuck in my throat but I tried to carry on. “Umm… I heard that girls and stuff were a lot more transparent and uhh… you could see things inside of them if you put it there. Is that true?”

Her eyes went a lot wider as I kept asking about it, but then it looked like she was about to giggle too, like she was holding on to some secret that she had been keeping. “W-well… yes… you can see things that have gone inside.”

“Oh…” I said, unsure how to feel right now. She confirmed it, but I still had no idea how that was possible. “But… how? Other crystal ponies eat and drink, but I never see anything go to their tummy.”

“Well…” Glass Slipper said hesitantly, biting her lip a little and thinking what to say. “It’s a little bit different from eating. Kind of similar I guess, but… different.”

I cocked my head to the side. How’d that even make sense? “D-do… do you think you could show me?” I asked as nicely as I could. She didn’t go and blurt it out already so it must be something she was keeping close.

Her face lit up with about half a dozen different expressions, but they all converged into one that scrunched her face up and filled it with crimson blush. “I… uhh…” she said hesitantly, looking around like she was avoiding to get caught by somepony. Her tail flicked around a little before she finally continued, “y-you want me to show you? A-are you sure?”

My face probably showed a lot of my confusion, but it was something I wanted to know. I finally cleared my head for a second and nodded eagerly. I wanted this. “Yes, I’m sure.”

“O-ok… I have something to help… l-lets go,” she said as she stood up and headed along one our passageways. It was a tight fit like usual, but I followed behind her. The only thing though was I could smell her… like a lot. It was like sniffing her mane when we wrestled, but with a hint of something more, like something crossed between damp and even more girly.

I gulped when my mouth started to water a little bit more. I was going to ask her if she had showered today, but decided against it; I kind of liked the smell and didn’t want to bring attention to it right now.

She finally stopped at the entrance to her part of this pile. She had hers and I had mine on the other side of the room. It was a place that we called our own, a second room of sorts. She lifted the pink blanket covering the entrance and signaled me to go it.

I was even more confused right now because it was so weird; she never invited me into there before. I probably wouldn’t have invited her over to my side either, unless there was something super important to share. We might have caused a bunch of havoc and chaos all around the house, but we did have boundaries on these two hidey holes, neither of us crossing those lines out of some form of respect or trust.

“A-are you sure?” I asked cautiously, wondering if she was actually being serious right now.

She took a moment, but nodded and ushered me in, so I followed.

The room was covered in what I could expect: posters and stickers haphazardly strewn about on the walls of this place. The one thing that I did notice was the little light hanging down from the makeshift ceiling, brightening up the place. “Hey, cool!” I said excitedly, jumping on the mattress that covered the floor. “I wish I had one of those lights!”

She smirked a little and nodded. “Well there are lamp parts if you can find them and I found a plugin on the wall. Yours probably has one too if you’d look.” That was a pretty good idea, I hadn’t even checked behind the boxes around my own spot. I hoped to have twice as many plug-ins, with even more lamps!

Glass Slipper pushed aside a few boxes to reveal a little compartment hidden away. She pulled out a small shoe box from inside. It had a red tie or scarf tied up and holding it securely. I peeked over her shoulder to look at it. “What’s in the box?”

“Just one second and I can show you,” she said as she started to undo the knot. The piece of fabric hit the floor as she looked up at me with her hoof on the lid, ready to open it. “A-are you sure you want me to show you this?” she asked once more, almost looking like a tomato with how red her face was all of a sudden. It was also strange how that unique scent had just flooded into this room, hitting my nostrils, pressuring me to take deep breaths of that inviting scent.

I still wanted to see what this was all about so I nodded without hesitation. She opened the box and inside was a blue, rubbery looking thing. It almost looked like a short and fat cucumber, or like a wiener. I couldn’t help but giggle. “Hehe, what is that?”

“This will help you see something in me, when it goes… um… inside…” she said, sounding like she was having as much trouble speaking as I did when I first asked her this question. The next thing however I did not expect. I was picturing her putting the weird thing into her mouth or something, but no! She placed the rounded base of it on the ground and sat on it!

“W-what?!” I said in surprise, watching her wiggle on top of the pointy toy. She winced a little, but didn’t make a sound as she carefully lowered herself, save for a long exhale when her rump finally hit the mattress below. Her eyes fluttered a little bit and she was panting. “Mmmm~ t-there,” she said as she finally looked up at me and smiled.

I watched it and could see it clear as day in her tummy as it slid right in. I grinned from ear to ear in excitement; it was there and the mystery was actually true! But my smile started to fade as even more questions popped in my mind. How? W-What?!

“Wait… how’d you do that!?” I said in surprise at this almost magic-like act. Was there something I was missing? Where’d she put that? Did she have a pocket or something that it just kind of fell into? I couldn’t help picture a kangaroo pouch that she had on her butt.

I couldn’t help but wiggle closer as she stood up. “S-see… you can see it inside me,” she said with a mix of emotions; something between embarrassed and excited. She was right though, I could still see the length of it stuffed into her somehow and the end of it coming right out from between her flanks; though I couldn’t see exactly where from at this angle with her looking at me.

“I… I usually wait a little to put it in, b-but… I didn’t think you wanted to see that,” she said hesitantly before looking back at the toy too. “It’s weird how you can totally see all of it?” she said, pressing at her belly like she was trying to get at it, almost like she could just reach through her sparkling, blue-grey fur and touch it. I could see the toy twitch inside her, like somepony was just gripping onto it tightly and then relaxing.

“But how’d you get in it there?” I asked curiously, walking forward and touching at her belly too. It made my heart beat faster and my gut feel weird again, tightening up from being so close to her right now… and surrounded by her intoxicating aroma.

She looked at me oddly. “You don’t know?”

My face only confirmed her suspicion.

“Oh, well I just put it here in my crystal caves, hehe,” she said as she turned around a little. My hoof trailed along her until it ended up on her flank, right where her cutie mark would have been. When she moved her tail over, that’s when I saw it; I could see the base of the blue toy and slivers of pink flesh hugging it.

It almost looked like some kind of mouth with its two, puffed out lips tightly gripping onto that intruder. Her blue-grey fur around it looked wet too, enough that I could catch a droplet trying to run down her thigh. I could feel the saliva building in my mouth, enough that I had to consciously stop from drooling. I had no idea why, but the sight of her backside and the scent that flooded my senses, had my entire body spinning on overdrive.

My heart was pounding in my chest and my belly, all the way down and between my legs was tensing up. “Humm-um num um na num,” I said so eloquently; the best that my brain could come up with right now.

Glass Slipper giggled a little from my dumfounded expression. “Y-you know what’s even nicer? Watching it move,” she reached her hoof back and grabbed at the base. I had to take a step back, and just watch her. She turned to the side, just enough so that I could see the toy retreating from her tummy and slowly sliding out from those folds, covered in a damp sheen that glistened in the lamp light.

“Nnnph~” she exhaled with her mouth half open and squeezing her eyes closed. She almost had the entire thing out before she slid it right back in with one quick hoof motion and gave a little squeak. “Mmmm… s-see?” she said with heated breath, slowly working the toy back and forth with shallow strokes, but fast enough that a wet squelch came from those soaked lips.

“Hehe, s-sorry,” she said, at the sudden noise. “It does that when I umm… grip on too tight.”

I finally blinked a little and shook my head to try and clear up any thinking power. “N-no, t-that’s fine,” I said simply; my brain had nothing to say or even think right now, but my body helped me speak up. “C-can I try?”

“What?!” she said back in surprise, almost like she didn’t expect that kind of reaction at all. “U-umm… a-are you sure? It kind of gets all wet and sticky back there after a bit,” she warned.

I couldn’t help but take a step forward and tentatively reach a shaky hoof out. “Y-yes, I… I want…” I managed to say.

She looked like she was thinking it over for a moment before finally removing her hoof and sticking her butt closer to me. “O-ok… j-just go slow… and not too deep! This thing is small and I don’t want you to get it stuck inside me.”

My hoof touched against the toy and she was right, it was wet. “O-ok… slow…” I repeated, gently pulling it back in my hooves, feeling it start to glide back. Though it was hard to pull softly, her tunnel was grabbing back at it, almost like I was playing tug of war.

“Mmmph…” she slowly moaned, as I slid it back and forth. It was so strange looking at a girl from back here. Honestly, I never even had a peek behind their tails, like I knew other boys had done long ago. It was like a whole new world back here, staring at her filly parts spreading apart so easily and watching her tailhole tense up and visibly twitch when I started to push the toy back in.

Every time I pressed it inside I went right up to my hoof, pressing it against her feminine mound. Wow, was it ever warm, and she was right again… it was sticky. I could feel her dampness cling to the edge of my hoof and thin strings of liquid bridge the gap as I pulled away.

She was panting hard and visibly shuttering the longer this this went on, and it had been getting to me too. The tightness in my gut had expanded out and I could feel the cool air on my colt piece as it started to slip from its sheath. It had gotten kind of stiff before, but nothing like this. It felt rock solid, and was throbbing as hard as my heart was beating.

I hope she didn’t look back and see, but at this point I didn’t care, I wanted to continue pressing this thing in her. This was a fun game.

“A-ahh~!” she squeaked out again with an even higher pitch, followed by a long moan. “A-a little faster now C-Crystal Step. T-that’s it,” she panted out, and rocked her hips back and forth at me, sliding quickly down the toy and hitting into my hoof harder each time. Between her filly parts, my stiffness down below and the thousands of questions spinning in my head, I focused as much as possible, holding onto the slippery toy, daring not to let go of it.

I could see the toy through her flank, watching it get buried deep inside her every time I pushed in. It was like it was going down some secret tunnel inside her that I had never known about. I certainly didn’t have the parts, but… I was feeling happy to find out that she did.

“F-fast… ah… er~!” she squeaked out once more. Her hindleg lifted and twitched, while the rest of her seemed to tense up all of a sudden. She quickly reached out and grabbed the nearest cushion, biting down on it and screaming out with a muffled cry. I could see her filly parts quiver and clench around the toy and I brought my head close to get a good look, but suddenly I felt a warm blast on my hoof and droplets of liquid spray all over my face.

“Ah!” I shouted out in surprise, pulling my hoof away and leaving the toy almost fully inside her. Instinctively I tried wiping it off my face, but used the wrong hoof and smeared that filly’s juices all over. I couldn’t help but groan a little as I plopped down on my flanks and wiped with my clean hoof.

“Ugh, sis. What was that?” I said, still trying to clean, but really getting nowhere. Though after a few moments I could start to smell her again, like really smell her. I could feel the throbbing down below get even more urgent and my mouth water as soon as I looked at my hoof.

“Mmm… s… s-sorry,” she panted out, trying to catch her breath for a moment as she cooed and rolled her hips. “I… phew… I… mmmm…” she tried to say as she looked back at me. I’ve never seen her look like that before, just watching me with an expression that I just couldn’t point out exactly, but she definitely looked happy.

“T-that’s alright,” I said out of habit as I watched her too, but then she looked down on me and her eyes lit up.

“O-oh? What is that?” she said as she tilted her head. It took me a few moments to figure out what she was saying.

Oh no! She was looking right at it!

I crossed my hooves, awkwardly trying to hide it, but with it being so big and hard all of a sudden I wasn’t having much luck. She turned to face me, bobbing her head around to look past my hooves. “Oh come on, let me have a look at it,” she pestered quickly.

I couldn’t help but blush and slowly pull my hooves back, letting it spring free into the air, standing at attention and pointing at the ceiling. I wanted to say something to stop it, but just held my tongue and awkwardly glanced to the side.

She stared at it for a few moments, before reaching a hoof behind her to pull out the toy. She held it in her hooves and wiggled it around as she sat down; the toy was completely glazed over in those sticky fluids. “I’ve never actually seen one of those, when they’re like that,” she mentioned as she looked back to me and my hardened friend.

“O-oh? A… a first for us both then?” I said nervously, finally being able to look her in the eyes again. She was just glancing up and down at me as she played with the toy in her hooves. It was weird, but I swear her fur looked just a little more sparkly than usual.

“D-do… do you think I can touch it?” she asked, staring up at me intently and taking a hesitant step forward.

My heart was pounding in my chest and I thought it was going to fly away as soon as she said those words. “U-uhhh… uhhh… ahhh… s-s-sure,” I stammered out, leaning back a little while pushing my hips towards her, making the entire tower wobble.

I gulped when she reached out her hoof. She gingerly gave it a few pokes, testing with a hoof before finally holding onto it. Her hoof felt so soft on my sensitive skin, and her dampness was rubbing off on me, I could feel it sticking as she poked around.

“It’s so warm,” she said, “and so stiff.” She gave it another poke, illustrating her point as it barely moved. Then she poked it again, and again, watching as it wobbled side to side even faster. “Hehe!” she giggled.

She tired poking it harder to get it to wobble faster, but I stuck my hooves out. “Hey! Quit it! That feels weird!” I said, sitting back up suddenly and keeping her curious pokes away.

Glass Slipper just giggled at my plight, but then a curious expression crossed her face as she stared between me and the toy. “Huh… I wonder if colts can do the same thing as fillies,” she said casually.

I certainly had no pocket to put things in like she did, but when I looked down I saw a teeny little hole on the tip. She saw it too. I crossed my hooves in front of it defensively. “There’s no way that it’s going in there!” I said in a fright, “those things are the same size!”

Almost as if I had said a new truth to her, she eyed up the toy and my member. “Oh… wow… you’re right. And they… do look the same,” she said, biting her lip a little, looking like she was thinking something that was taking up all of her brain power right now. “W-wanna see what it looks like inside me?”

My mouth hung there slack jawed. I could feel the pulse growing in my loins. She wanted me to put my thing inside her? Inside that wet little pocket that felt like it was on fire? My mind was telling me yes, but my body… was screaming at me yes.

I could only nod and give out a quiet, “uh-huh.” I wasn’t getting that toy put inside my stick, but this was something that felt worth trying.

She put the toy down on the mattress and scooted a little closer to me. “I-I’ve never done this before, so… I don’t know,” she said. Her face still had a red glow to it, and I wondered if her heart was beating as fast as mine. I practically felt like I was another pony, just watching down on this entire act. Her fur touched mine, sending shivers down my spine as she half stood up and wiggled onto my lap.

Finally, she raised herself up and just stared at me, almost like she was preparing herself. I kept my gaze downwards, looking right through her to my throbbing self below. It was so strange seeing myself like this through my sister; I could only imagine what it was going to look like when it was as deep inside as that toy had been.

“Ah~! Aaahhh~” I let out in a startled surprise as she lowered herself and that heat touched against my tip. She reached a hoof down, angling it correctly and rubbing the end against her folds below. Shivers exploded up my spine, making my belly clench tight all of a sudden.

Glass Slipper seemed to find the right spot, because she started sinking down all of a sudden and my world became just the two of us as I silently squeaked out. Her velvety smooth tunnel slid over me easily with the slick wetness that filled her, but that was the only saving grace because she was gripping onto me hard. I could feel her entire passage clench and release, over and over again like it was trying to massage something from me.

On top of it all, it felt so warm. It was like I had put myself inside a volcano with that wonderful, wonderful heat. I could feel her lava trickling out form her and running down to my tail, but my body was still screaming for more.

“Oh G-Glass… y-you’re so… t-this is…” I tried panting out, but couldn’t really make any words.

“Hehe, I think that means you like it,” she said with a teasing smile and stuck her tongue out at me for a second. “But look,” she said as she leaned back and looked down. “There you are.”

Through her fur I could see myself buried deep inside her, right where that toy had been. It was twitching so much inside her, but I could feel another pulsing down there too. As we sat there and looked, I could truly start to feel her, and her heart was beating just as fast as mine.

“I… already finished once, but... I feel like I might be able to do it again,“ she said as she gazed into my eyes. She almost looked like she was hungry the way she stared. “I… I haven’t done two in a row before, but… it really feels like I might be able to do it this time.”

She wiggled around, almost like she was making herself comfortable on top of me. “C-can you finish as well?” she asked, but I just shrugged my shoulders. I had no idea if I could or not, nor what she was even meant by that. “W-well… want to find out with me?”

“Y-yea,” I said simply, nodding my head like and eager puppy.

She smiled brightly as she started to rock herself up and down slightly. “Since you got me to finish… I can see if I can get you to do it as well!” I kept nodding; I certainly wasn’t going to say no to her. Not with the way she had been squeaking and moaning from the toy.

She started to bounce up and down in my lap, only driving the point home that I wasn’t going to stop doing this when I could practically feel electricity running through every nerve that I had. It was like a hot, cozy tube sliding along, making me feel things I never could have imagined before.

“You… f-feel so amazing… G-Glass Slipper,” I managed to blurt out as she put her hooves on my shoulders, balancing herself. I had to put my hooves behind me to support the both of us from tumbling over.

She had started off slow, carefully bringing herself to the top, before sliding right down and plopping her rump in my lap each time. It made me squeeze my eyes tight, but I fought to keep them open; I wanted to just watch myself move inside her. However, now she was starting to get a rhythm going, getting a little faster the more that it went on. It was getting harder to concentrate and I could feel something stirring in my gut.

She rested her head on my shoulder and I could hear her small moans and whimpers as she bounced up and down. “Mmmph… I… I’m g-going to f-finish soon…” she whispered into my ear.

That sentence made me want to be inside her for as long as I could. I couldn’t help but try and thrust into her, bucking my hips up and meeting her when she came down. A wet slap pierced the air every time we came together like that.

My crotch was completely soaked in her filly juice and I loved every second of it. “F-faster,” I said to her, copying what she said earlier, but pleading that she could do the same thing for me now.

“O-ok…” she panted out before hugging onto me tightly, and focusing everything on moving her hips faster. The lewd, wet sounds filled the air as we slapped our bits together. The tingles and lightning were shooting out from below; her entire tunnel was tickling my member. I just wanted her to scratch that tickle, that itch building up; feeling like it was just going to erupt.

“A-ahh~ G-Glass… G-Glass G-G-G… n-nnnyaa,” I moaned out loud, feeling like the floodgates had opened and something was coming. My belly tightened as I thrusted one last time up to her, trying to get as deep as I could while she rode me.

I could hear her squeals in my ear. She was trying to hold herself from yelling out, but failed stay silent in the slightest. I could feel her clench down on my erupting member with all her might; her grip was so tight.

A hot wetness blasted out and covered my legs, feeling just like the drops that had sprayed me earlier. I pressed my head right into her as I stared down through her fur at the action below. My loins tightened and I could see my tip expand as a thick, white goo shot out from it, making her purr as soon as she felt it fill her insides.

It pooled right at my engorged tip, plugging the new liquid from escaping as we sat there. Both of us were panting hard, pulling back a little and looking into each other’s eyes.

She smirked first but we couldn’t help but giggle and hug each other tightly. This whole thing had been amazing and she felt magical, but my hooves were tired so I slowly flopped backwards until she was resting on my chest.

“I… I knew I could do two… a-and I think you did one as well…” she said, looking at me with half-lidded eyes. “A-and… oh it feels so warm too.” We couldn’t help but take a look back at the whiteness pooling deep inside her. My colt piece started to quickly recede and flopped out from those warm depths.

She rolled to the side and down onto the mattress, lifting her head up to get a better look. I wiggled over as well to get a good view through her belly. “What is that?” she asked curiously.

I just shrugged. “I… I don’t know,” I said as I brought my face closer. I couldn’t help but kiss her belly, right where that white goo was. “But… I think I like it.”

“I think I do too,” she said as she smiled and touched my shoulder while I nuzzled her belly. Between my legs it almost felt chilly without her heat surrounding me. I had found out the answer to my question in the best of ways, and… I think I would to like to try this out again in the future.

Author's Note

Well, one mention of crystal fillies and a picture that may have these numbers in it 1504531, made me write out this story unexpectedly over the last few days. It was fun exploring the transparency of a crystal filly. I quite enjoyed writing it and I hope you enjoy reading it as well.

If you would be so kind as to comment on the story if you liked it, I’d really appreciate that. Or if you have any edits that need to be made, please PM me and I’ll fix them right away.

Also, wanted to mention that since Discord and Reddit are having a big ban against cub (This includes foalcon), there’s a new discord-like chatroom with a lot of popular artists and authors in it, as well as an active and growing community. I do let people check out stories early as well, before they are public on FimFiction. Check it out at Rocket.Foal.Party if you are interested and want to join the party.
