Author's Note
Yeah I wrote this real fast because I had an idea and wanted to roll with it. plenty of mindless clop for those who want it. Not naming names, but if you know who the characters are, then good for you.
IT BEGINS
A door opens to a young mare's room, as the shadow from the hallway illuminates the inside. The silhouette of a young colt with long hair covers the room as they enter, slowly closing the door behind themselves to not make a sound. The room's owner wasn't there, but one should always keep good habits, right? The colt's heart was racing in their chest. They didn't know why they felt what they felt, or what it was. They just felt compelled to go in here and look for... something.
As they close the door, the lilac coated earth pony turned on the lights in the room and headed towards the dresser. They didn't know what they were looking for, only that they were curious about the contents. They also felt a bit of guilt. This mare was their friend and let them live with them since he had no place to go, and here he was, snooping around her room. It wasn't like she was going to know, though, he had at least two hours before she came home.
He opened the dresser and brushed his long blue mane out of the way of his eyes and gazed upon the contents. There were lots of panties folded nice and neat, but one of the smaller pairs caught his eye. It was a light, soft pink with a cute white bunny face on the front. It made the colt blush and they pulled it out and set it on the bed. They remember a few years back accidentally entering the room without knocking and seeing the young mare toss the panties back into the dresser, complaining that they were too small to fit her. They seemed the perfect size for him now.
The colt closed the drawer and felt an urge to look for other clothes she might still have that would fit him now. He started going through the drawers and found a cute pair of stockings with some frills on the ends. He set those aside on the bed, next to the panties. The next drawer he opened up had an old school uniform that the mare had once worn. He placed that on the bed as well. After not finding anything else of interest there he closed the last drawer of the dresser, his heart pounding with excitement for something he didn't know as he trotted over to the closet door, opening it to reveal several dresses and shoes, including a cute pair of black heels that seemed his size.
Blushing while he did so, the colt grabbed the shoes and galloped back to the bed. They had found these clothes that were his size, and he couldn't understand it, but he felt like he wanted to try them on. Like he was being called to play dress up. He started with the panties, of course, sliding them up his hind legs, feeling the soft fabric caress his coat as he pulled them over his hindquarters, guiding his tail into the pair of panties appropriately. the feeling of the tight panties felt right, kind of like it was meant to be. The colt felt their heart race even faster as they then reached for the shirt and skirt, putting them on and making sure it looked nice and proper, shirt tucked into the skirt all proper-like.
Then came the socks. the colt carefully pulled the socks over their hind legs until they reached as far up as they could, which was most of their leg. They then put on the heeled shoes and made sure they were in a nice fit before walking over to the mare's vanity, taking a hairpin and putting it in their own mane. As the colt stared into the mirror of the vanity they couldn't help but blush at what they saw. It looked like a filly was starting right back at him. The colt felt strange about it.
There was some feeling that came over the colt. An unfamiliar, slightly uncomfortable, feeling. but it felt good. Like butterflies in their stomach, but not as anxiety-inducing. The colt felt their panties grow a little tighter. It felt uncomfortable, sure, but it also felt good. Confused, the colt went over to the bed and laid down on their back, head resting on a pillow. They slowly reached down and started lifting up their skirt, noticing the panties starting to bulge where their tiny colt member was. They didn't know what was happening, as they had never felt like this before. it felt good, but confusing as they just sat there, staring at the bulging panties, completely transfixed on the article of clothing and what lied underneath.
The colt laid there, unaware of the noises outside the house, or within, as the young mare who owned the room arrived home early, much earlier than usual. They didn't even notice as the door was opened and the young mare saw the colt dressed up like a schoolfilly, getting erotic enjoyment from wearing the clothes. The mare didn't feel angry or disgusted, mostly just shocked, confused, and perhaps a bit happy. For one thing, her old clothes were getting used, but also.
The colt's attention was broken when he heard the giggling. In shock they looked up, their heart pounding hard in their chest as they stared straight back at the mare, her blue coat and yellow mane illuminated by the light of the room. They froze in fear, unsure of what to do.
"I see you're enjoying yourself int hose clothes, huh? Stay right there, I'll teach you how to really enjoy them." the mare said, walking over to the bed towards the colt. She bent down and grabbed a few boxes from under the bed. She opened the first one, revealing some ropes with some straps on them. The colt started to whimper, confused and worried about what was going on as their member twitched a little under the panties. "Shhhh, it's gonna be fine, I promise. You'll like it" the mare said, comforting the colt.
The colt tried their best to not whimper, still very confused about what was happening as the mare slid the rope parts under the bed, leaving the parts with straps hanging over the sides under the mattress. "Turn over, sweetie, and stand up for this one." The colt heard her request and obeyed, turning around and standing on the bed. The colt then gave a yelp of surprise as they felt their hind legs get pushed apart a little by the mare as they proceeded to wrap something tightly around his hind legs near his hooves.he then heard some clicking noises and when he looked between his legs he noticed a metal bar in between his hind legs.
"Trust me, sweetie, this will all feel good." The mare comforted, trying to ease the colt's worries. The colt, still confused, just faced forward again before the mare grabbed his front hooves and tied them together, pulling them in front of him so his rear end was raised into the air. The colt felt his member feel needy and didn't understand what was going on, blushing intensely as they simply whimpered. The straps from the sides of the bed were then pulled and stretched to the colt's limbs as they too were fastened. The Mare then went to the closet, opening a box in there and pulling out a large plushie in the shape of a stallion. She laid the plushie on top of the colt, seeing that it was big enough to mount him. Smiling, she took the stuffed toy off and found a strap-on, putting it on the toy.
"So you want to be a filly, then? Alright, but I'm gonna have to train you to be one. I hope you're ready to face the consequences of your choices, kiddo." She said as she lubed up the toy and gently pulled down the back of the tailhole of the colt's panties, slathering a bit of lube around the colt's anus, making the colt feel funny around there like he did in the front. the colt couldn't help but moan out loud at the feeling, which made them even more confused about what they were experiencing. They didn't know how to feel about these sensations, but they felt so good. Maybe they were worth feeling.
Hearing the colt moan, the mare giggled a bit more and slowly started inserting the large horsecock from the strap-on into the colt's rear, slowly going further and further until the entire toy was sheathed inside the colt, whose mouth was hanging open as they felt the massive toy be inserted into themselves. A pathetic mess of moans came out of the colt's mouth as the stuffed stallion had mounted him.
"Heh, what a noisy fellow. Listen, kid, I'm leaving for tonight and won't be back until later tomorrow, so I came home early to pack up. I hope you'll become a good filly by the time I come back, but first..." The mare grabbed a ring gag and popped it into the colt's mouth, securing it around their head, forcing their mouth open as the mare then stuffed another horsecock dildo through the hole, using another strap to secure it in place. "How about we shut up that noisy mouth of yours~ Anyways, I just needed to grab a nice dress for tonight. See ya tomorrow, little filly~" The mare used some tape to secure the plushie to the colt before flicking a switch on the dildo inserted into the rear end, causing it to start vibrating in erratic patterns. She gave a kiss on the cheek of the colt before putting a blindfold on them and then finally leaving through the door. "See ya tomorrow~"
The colt was alone, feeling all sorts of intense and wonderful sensations, helpless as they experience an ecstasy they had never thought possible. the moment the door closed the cold screamed out in orgasm around the dildo in his mouth as he spurted out his cum into the pair of panties he was wearing, causing some of it to leak out through it. The world melted away as the colt felt nothing but orgasmic bliss for several hours straight.
The mare finally came home a little before noon the next day, heading straight to her room. After undoing all the bondage and taking the dildos out of the colt, they sat them down on the bed. "So, how was it, kiddo?" She asked.
The colt grabbed the stuffed stallion, blushing a bit as they look back at the mare. The colt told the mare "I-I think I like being a filly." before smiling and closing their eyes, their body going limp. As the colt passed out, the mare giggled, taking the colt out of the schoolgirl clothes and putting a small nightgown on them before carrying the sleeping colt to his own room, laying them down with the stallion plushie, the strap on taken off for cleaning. "Sleep well then, princess." The mare grabbed any clothes of hers that fit the colt and laid them neatly, inside his dresser before going to clean up the mess he made in her room. The colt slept peacefully until the next day, waking up only for a quick dinner the mare had made so he wouldn't go hungry.
