I was waiting at the door while my sister talked with Mr. Fancy Pants about opening her new boutique in Canterlot. Rarity had told me that her whole business depended on the outcome of this meeting. And although at the moment they seemed relaxed and were occasionally laughing, I couldn’t help but be extremely tensed. I loved my sister and I was afraid to ruin their idyll when it was time for me to join their conversation. So I was drawing bunnies in my mind to calm my nerves, as I heard my sister calling for me.

“Sweetie Belle, come here. I want to introduce you to our guest.” She cooed out from the living room.

I walked over to the couch they were sitting on and made a curtsy in Fancy’s direction the way my sister had taught me, making him smile back at me. Rarity slapped a spot on the sofa between her and Fancy, inviting me to their conversation.

“Tell Mr. Fancy about yourself, Sweetie,” Rarity said, as I tried to accommodate myself on the seat. There was not enough space to sit, let alone move, so I was stuck between her and Fancy.

“Mm, I like to draw and sing,” I said, “I also like to help other foals to get their Cutie Marks. We even have our own headquarters in...” I trailed off, as I noticed Rarity’s stern look on me. “But of course I love my sister more than anypony and I will do what l can to help her with her business,” I proclaimed firmly.

“It’s so adorable. Sweetie, dear, do you have enough space?” Rarity asked. “Why don’t you sit on Mr. Fancy’s lap if he doesn’t mind, of course.” She looked at him, moving her tongue to one corner of her mouth.

“Oh, I don’t know, Rarity. Is it okay with Sweetie Belle?” 

I could feel a tinge of uneasiness in his voice and it wasn’t meant to be like this. I collected my thoughts and remembered what Rarity had told me to do in such situations.

“Please, Mr. Fancy,” I murmured softly, “you would do me a favor.”

“Ahem,” Fancy cleared his throat, “if you insist, dear.”

I climbed on Fancy and spun around in his lap, trying to get the best spot. My head was right underneath his, my legs splayed out on top of his and I could feel Fancy’s heartbeat, as my back was against his chest.

“So,” Rarity proceeded, “My last clothing line is greatly popular over Ponyville and I already have a lot of orders. All I need is twenty thousand bits for initial capital investment in my new boutique in Canterlot. I guarantee it will be a gold mine for both of us.”

Fancy deliberated for half a minute before giving his answer.

“I understand your excitement and I recognize that you’re an outstanding designer and yet I made my money through my skills to assess risk. And you should know that your collection will hardly find high demand in Canterlot. I can lend you only five thousand bits and a place near the edge of Canterlot. And then we’ll see.”

Although it seemed that Fancy didn’t notice that my sister’s facial expression changed, it was clear to me that she was in a rage. The little furrow appearing above her nose spoke for itself.

“Fancy, let’s not get ahead of ourselves. You promised me that you would be here for me until evening.”

“Of course, Rarity. It’s always a great pleasure being with you.”

While they were talking, I felt the watermelon I’d eaten this morning struggle to get out. And though my thoughts were traveling out here and to the restroom, I knew I couldn’t leave this room prematurely under any pretext. Rarity was counting on me. She had made it clear that without my help she hadn’t many chances to tip Fancy on her side. I couldn’t fail her, I just had to make it to evening.

“Did you hear of the last Sapphire Shores’ album? They say that it’s topping the charts now.” Rarity tried to keep a conversation going.

“I’m afraid I’m too busy for such things. You know, I carved out a day only because you’re my good friend.”

“Yes... Thank you once again, Fancy,” Rarity said uneasily.

“Are you alright, dear?” Fancy asked me as I wriggled uncomfortably in his lap. 

“I’m ok.” I tried to feign a smile. The pressure in my bladder was getting worse and the watermelon inside of me began to push itself out to my brim. As I squirmed, I began feeling something solid rub my nether parts. I looked down and saw Fancy’s cock peer out beneath me. It was almost wholly hidden in his sheath but even the tip of it was enough to rub over the most delicate parts of my slit. This feeling overflowed me and I wet myself.

“S-Sweetie Belle!” Rarity gawked, as a rivulet of warm lucent liquid trickled down Fancy’s groin and onto the sofa.

“I’m sorry, sis. I just couldn’t hold it back anymore. I’ll run to the kitchen and fetch a rag.”

“No, no, Sweetie.” Rarity threw a harsh look at me. “We don’t have time to do it. You clear your mess up right now before it saturates Fancy’s fur.”

“It’s not a big deal. I’ll just go to the bath...” Fancy trailed off, as I started to lick his groin, a place where my leaked fluid had accumulated the most. I run my tongue up and down his thighs, lapping up the liquid I had spilled. It was a bit salty with a sweet flavor of watermelon, each lick leaving pleasant savor on my taste buds. While I was brushing the side regions with my tongue, Fancy’s cock rapidly swelled to a great size, poking into my muzzle. I took a long lick along his shaft and over the top of his flare, collecting the sweet-salty liquor. I paid special attention to the crown, excessively smearing my saliva against its surface as a cleaning fluid.

“Don’t forget about the balls,” Rarity said instructively. She had been assessing my skills since I’d started my cleaning work. I had to do my best to prove my sister that she can be proud of me. 

I lowered my head, immersing my muzzle into the fluffy bag, the big rocks covering my mouth and nose, so I’d had to take a deep breath before plunging in. I rapidly swirled my head around the scrotum with my tongue stuck out, trying to cover the whole area with my saliva. After I’d finished it and got an approving nod from Rarity, I moved back to the flare.

There were viscous droplets on top of it. It was strange since I was sure that I’d cleaned that spot particularly carefully. Wondering what it could be, I took a lick on it, savoring the strange substance. In addition to being salty, it had a strong dizzy musk that sent the pleasant waves to my mind. I didn’t know why, but at that moment I craved for it more than for anything else. Unfortunately, there was only a morsel of it and that certainly wasn’t enough to quench my hunger. So I quickened my pace, trying to squeeze nectar out from the bulb.

“Sweetie, dear,” Rarity murmured softly, as I desperately licked the tip, “You devote yourself to the task, but you lack experience in it. Let me help you.”

She grabbed the back of my head, pushing me down into the shaft until my mouth filled up to the brim, the bulb brushing my palate.

“Your problem is that you use your tongue, but you completely forgot about your precious mouth,” my sister said, moving my head up and down along the pole. “In this way, you not only work on the tip, but it also covers a part of the rod. As you can see, it’s much more efficiently than just licking.”

As my head was bobbing on Fancy’s cock under my sister’s hooves, I could feel a vibration occurring in my mouth, something important was going to happen. And though my sister was helping me, I wasn’t quite sure if I could finish this the right way.

After a few especially strong thrusts that caused me to gag, Rarity lifted my head up, a squelching sound echoing through the room. Since my head was above the cock, I had an opportunity to take a look at it. It was even bigger than when I started licking it and now it was throbbing, ready to burst its seed at any second. 

“Hold your breath, Sweetie,” Rarity said softly, “There’s going to be a flood into your mouth.”

I took a deep breath, excited about finally drinking that white honey. I hadn’t had the chance to take a good taste, but it should be delicious according to what my sister had told me.

Once I had been prepared, Rarity slowly eased Fancy’s cock in my mouth. Of course, the whole thing didn’t fit my immature orifice, but both Rarity and I did our best to make it as far as possible. Eventually, she managed to place a half of it in my opening, my lips hugging tightly the medial ring.

“Rarity, I’m going to cum,” were the first words that crawled out from Fancy since I’d started my work, heavy breathing accompanying it.

“Remember, Sweetie, you have to drink all the seed until the last drop. Don’t spill anything,” Rarity said, stroking my mane. It was as gentle a touch as only a loving sister could give.

“Yef, fsis,” I muttered, as a hot jet hit the back wall of my palate and run down my throat. Startled by such pressure, I wasn’t ready to a second wave that struck at the top, sloshing over my mouth and onto my tongue. I wanted to swallow it as a next squirt bumped right into the entrance of my throat, causing me to deeply gag. I tried to raise my head to take a breath but Rarity held me firmly on Fancy’s cock so that I couldn’t move up an inch.

“Sweetie, dear, no need to hurry. Wait until all his semen reach your mouth otherwise, you’ll mess all around again,” Rarity murmured, pushing my head down.

While I was trying to clear my throat, sperm began to fill up my mouth, inflating my cheeks up to a maximum capacity as if they were two balloons ready to blow up. And though my lips clutched tightly around the rod, the pressure was so intense that the white rivulets of jizz were seeping out along the entire edge. I worked my oral muscles madly like a pump, pumping the seed from the lake that formed in my mouth down into my belly.

Gulp after gulp of semen splashed down through my gullet, filling my stomach with a warm weight. Eventually, spouts ceased and Fancy pulled his cock out of me. Unprepared, I barely had time to shut my mouth so the sperm could not leak out through the hole that had been plugged with the cock just a moment ago. I took a short break before continuing swallowing, breathing heavily through the half-stuffed nasal passage.

“I’m fsorry sfis, itf too much,” I bleated, trying to say it as distinctly as possible if the word “distinctly” is even appropriate for a pony with her mouth filled to the brim with semen.

“Sweetie Belle!” my sister scolded, giving me a stern look, “Where are your manners? It’s not proper for a lady to talk with a full mouth. You swallow it all completely, then you speak.”

It took me a few minutes to send all the cum from my mouth into my belly that already started to swell a little because of the enormous amount of semen in it. In the end, I felt pleasant heaviness down there.

As I finished, I licked the remains off my lips and opened my mouth wide to show my sister that I’m done, waiting for permission to speak. 

Rarity examined me thoroughly with a long glance and then traced her hoof under my nose.

“Something has leaked through your nostrils,” she said, bringing the hoof down to my mouth.

I sucked the white liquid off her hoof, chastising myself for letting it spill out.

“Good. Remember, Sweetie, a lady always swallows first.”

“I’m sorry that I couldn’t drink it all up in the beginning,” I said, this time with a dry mouth, staring pitifully at the floor.

“It’s all right, you’ve done fine for your first time. You will improve your skill with each new fellatio you’re going to do. It’s just about doing your best. I believe in you, Sweetie,” my sister reassured me.

“Thanks, sis,” I said smiling with my mood drastically improved. “I will do my best.”

“Though you’ve done well, you reached only to the medial ring. I’m afraid your mouth is too small to fit the whole cock,” Rarity said, turning to face Fancy. “Fortunately, my dear sister knows not only how to work with her mouth but also with deeper parts of her body. Have you ever fucked a filly’s throat? It’s much tighter than her pussy. Go ahead and try it, we have to finish what we started. The base of your dick is still covered in Sweetie’s wastes.”

“Are you sure, Rarity?” Fancy said worriedly, “She’s hardly taken a half of it. I’m not sure it’s possible for her to take the whole thing.”

“What do you say, Sweetie?” my sister asked me, “Mr. Fancy doubts your abilities.”

“Mr. Fancy,” I said completely earnest, “I soiled your private parts and it’s my duty as a lady to clean it up. Please, use my throat as your cockwasher.”

“You heard her, Fancy,” Rarity said smiling,” put your cock in the place it belongs to.”

As I lay on my back with my mouth open wide and tongue stuck out, Fancy’s still erect organ loomed up in front of my eyes. With a swift action, it fell over and slumped against my neck, creating a dull sound. After sliding down, the thing approached my mouth, the tip brushing against my lips. Leaning over the sofa, Fancy made a few movements to get the best stance. He took a short step forward to get closer to me. He led the cock slowly into my mouth as if it was a ship making its way through storming sea to a placid harbor where it could get rest and care. 

At first, it was the glans that rested on my tongue. Fancy moved it back and forth, smearing the remains of the cum over my taste buds. I closed my eyes, indulging myself in a strong salty flavor of mighty stallionhood. Fancy was teasing me, sliding his crown down to the base of my tongue and then back to my lips. I was about to give up, about to just drain his cock, suck on it as hard as I could. About to just milk his seed into my mouth. But I stopped myself. I knew that I was just a fuckhole now. Just an instrument for Fancy’s needs. I didn’t get permission to do anything without a command. So I lay motionlessly, trying to change my thoughts. 

After finishing with my lips, Fancy pressed the glans tight against the tip of my tongue as if engraving his scent in my mind. A stream of drool run down the corner of my mouth. Then he finally let off my tongue and moved farther towards my throat, the medial ring scrubbing insides of my mouth. At this point, the bulb of the cock was now bumping against the opening of my throat, curving slightly since there was no way it could slip in through such a tight passage. And though I tried to relax my oral muscles, it was getting worse with each thrust, causing me to gag in a way that only tightened my throat. I could feel tears bead in my eyes from both pain and my inability to do such a simple thing as to swallow a cock.

I was about to bawl my eyes out as I felt a tongue lapping up my warm tears. Of course, it was my sister, she always comes when I need support.

“Hush hush, Sweetie, your sister is here,” Rarity said softly, taking a lick along my damp eye, “just relax and remember what I was teaching you.”

I was flooded with memories of how my sister and I had spent time together. After long kisses, she would show how to properly rub the lips of my crotch so that it would then be possible to reach the longest orgasm ever. She had shown me many things and of course, she’d taught me how to use my throat to take things in. Back then it had been just various dildos, neither of them had been as thick as the cock that was ramming itself into me right now. I didn’t know what to do with such a broad tool.

“You don’t have to worry, Sweetie. If you can handle my dildos, I believe you can handle a cock too without much trouble,” my sister reassured me as if reading my thoughts. Then she moved over me and started licking my neck. Her long deliberate touches soaked my fur with her saliva, making me feel cool and relax under my sister’s caress. Soon after that, I began to feel as the knob of the cock made its way through my entrance and down my throat. It was just the glans that came in but it was enough to make the rest of the way much easier. As my sister had told me: “Where there’s a crown, there’s a whole phallus.” And it was true, after a few hard thrusts a half of the cock was buried inside my gorge, bulging proudly under my neck.

As it moved along my tunnel, it felt not only longer and thicker than dildos I had been practicing with but also pleasantly softer, caressing my inner walls in the places where the tip was rubbing. In addition, I could feel my sister’s tongue pressing down in the rhythm of thrusts Fancy had made since he’d immersed the entire organ inside of me, leaving only the jiggling balls before my eyes. From both of internal and external stimulations working simultaneously against my throat, my eyes dropped down, my body went completely limp and by that moment all I could perceive was pleasant dizziness filling my mind. But as my sister had taught me, I knew I had to try to breathe to not completely pass out, so I was using any opportunity to take a short gasp during rare occasions when Fancy put his member out merely for a moment before shoving it back with a double force.

Since I was no longer in command of my body, I hadn’t any strength or will to hold back a tide that was accumulating inside my loins. A gush of my sticky filly juices was splashing out onto the sofa, my pussy burning, craving to be filled with a cock and be fucked at least as hard as my very luckier upper hole. Each thrust in my throat echoed through my whole body, causing a stream of my viscous liquids burst out from its basin.

“Poor Sweetie,” Rarity said, letting off my neck, “You must feel a fire down there.” 

I tried to give a nod but my head was firmly skewered on Fancy’s cock.

“Don’t move, Sweetie. I’ll help you. A lady is always ready for such a situation.” 

Rarity lit her horn and started to rummage through her saddlebags. And though all I could see was Fancy’s swollen balls bumping against my muzzle, I knew exactly what my sister was looking for: the toy my sister had given me to use when the heat inside my crotch was especially strong. She’d had it custom-made so that its form could fully match the curve of my body. It was the most precious gift I’d ever received from anypony. And lucky for me, it had a strap-on function so Rarity could use it on me effectively when I needed it. And I needed it in my pussy right now more than anything else.

After attaching the straps up to her groin with a muffled clang, Rarity made her way to my rear, shoving the dildo to the hilt inside my sopping wet pussy. The muscles of my vagina immediately clutched over the rod, my pussy happy to be finally filled. Thrusting her way inside of me, my sister bent and began to kiss my bulging throat.

I was stuffed from both ends now, my sister and Fancy working on my holes as a whole, penetrating my small body to the core, leaving me with nothing but a pure pleasure, the pleasure of being filled from top to bottom. And though my gorge was stretched and crammed by a massive stallionhood, my moans of pleasure were so intense it was vibrating along my throat, causing Fancy to hasten his pace. The only thing that wasn’t completely filled was my belly. And though there was already pretty much sperm inside of me and it was splashing around with each thrust, there was still enough room for more, enough space to stretch out... I desperately craved for Fancy’s release. Craved for being stuffed with his seed.

I felt the last final thrust into my throat – so strong and rough – that it knocked out the last shred of air I’d held in my lungs, his balls harshly bumping against my face. His cock stopped, throbbing and vibrating under my neck, preparing to launch all the seed he had inside his sack into my long-awaited belly. A heavy gush burst out from his glans, flooding me with hot waves of thick seed. It was more than before, more than I could ever imagine. As he was cumming, I felt a ticklish bubbling under my neck, so warm and pleasant as if there was a jacuzzi inside of my throat. 

My little body was stretching out, desperately trying to fit the seed Fancy was generous to give me. My belly was growing quickly with each heavy burst that was released into me. The first few spurts were quite easy to take. But on the third, there was so much sperm inside of me that I could feel my tummy began to point up. It was only on the fifth spurt when it subsided, my belly bulging to such a degree as if I got pregnant. In some sense, I really did. I wasn’t quite sure that pony couldn’t get pregnant through her mouth. I had to ask Rarity about that after we finished.

By the time Fancy released the last droplet, my own juices were squirting out abundantly on the dildo my sister was screwing me with. Each her thrust echoed through the room from both a squelching of my wet pussy and the seed that was sloshing inside my stomach.

The heat in my crotch overwhelmed me, straining my muscles and gushing out a fountain of lady cum. I didn’t see it but judging from a high shriek of Rarity, I must have squirted on her silky fur.

After I came, Fancy began to draw his cock out of my throat, my tongue brushing the rod and licking off any remnants of seed that might have left on it. As soon as he pulled out, there was nothing that plugged up my throat and some amount of sperm rushed up from my stomach. I shut my mouth, not letting any of it spill out, hungrily swallowing it back where it should remain.

I took a look on Fancy’s groin. His cock, previously hard as a rock, was currently flaccid and limp. His balls, previously plump and heavy with seed, were shrunken and completely drained. All of their contents were now mine, splashing against the walls of my stomach. I stroked my bulging belly as if claiming my new possessions. 

Soon, my sister pulled the dildo out of me as well and sat next to me, smiling and caressing my mane. There was a silence before Fancy finally spoke up. 

“Rarity, I have to admit that I underestimated you. You definitely have a talent to persuade ponies to do what you want. And I am definitely persuaded that our partnership would be productive for both of us. You’ll get all the money you need to start your business in Canterlot. I also know a mare who is fit to manage your new boutique perfectly. She is the cream of the crop. And if you don’t mind, I have many friends who would love to...” Fancy paused, clearing his throat and looking at me, “who would love to run a business with you.”

“What do you say, partner?” Rarity said to me, “Are you ready to expand our business?”

Partner. My sister had never shared business with me before. These were words I could only dream of. My smile grew wide from corner to corner and I answered the only way I could answer.

“Yes, sis!”
