It was a special day for Ponyville. One, that occurred regularly but all too rarely. It was a day particularly for foals, but was also enjoyed by older ponies very much.

In front of the school building were two rows of foals, one with fillies, the other with colts, all standing in a certain distance from each other. In front of each stood a sign on the ground, that listed their names and preferred kind of partner. All of the little ponies were excited. Some were a bit scared, some full of anticipation.

But all of them looked forward to what's going to happen on this third Breeding Day.

It was ten years ago, that Mayor Mare conceived this day. Back then, there was a lack of foals and the population of Ponyville was shrinking. It was clear that something had to be done, before it threatened to become a ghost town. The Mayor had the idea of introducing foalbirthing to fillies at an early age, to get some new "townsponies" out of them quickly and make them ready for future birthing. It was a controversial decision, of course, but the success proved her right. The population of Ponyville gained a new boost and Breeding Day became known as the best decision of her term (whether that was meant positively or negatively varied from pony to pony, but it was never meant ironically).

Since then, Breeding Day was held every five years, each time with some changes. At first, foals could only breed with adult and experienced ponies. On the second day, colts and fillies were allowed to do it with each other. Now, thanks to the alicorn magic of their very own princess Twilight Sparkle, mares and fillies could grow penises and testicles, full of fertile semen, that made it possible to cover more preferences and make this day more enjoyable for certain ponies.

And it was enjoyed by many. The "breeding ground" was well-visited, when Rarity finally arrived there, roughly an hour after it started. She regretted that she couldn't be here earlier, as her duties held her back quite a bit. After all, a cute little filly like Sweetie Belle would be desired by many, which she had to reject for now, as the two sisters promised each other that Rarity would be her first.

The row was long, but it shouldn't be too hard to find her. A filly that wasn't being rutted really stood out, as many of them were quite occupied. It was hard to look away from them, as their little pussies got stuffed by the cocks of many stallions, colts and mares. The smell of vaginal juices and semen gave the air a mesmerizing scent and the sound of moans were like background music for the whole event. It was little surprise that Rarity's new organ quickly left its sheath and hardened in not even a minute.

On top of being surprised at some of the... combinations (Fluttershy and Ginger Snap? Button Mash and Ruby Pinch? Filthy Rich and Twist?), the fashionista grew more and more aroused, as she went forward, looking for her sister.

By the time she found her, her cock was throbbing hard and some pre-cum ran out of the hole on the tip. She was pretty much ready to tackle her and fuck her hard. But she had enough willpower to resist the urge. Yet.

Sweetie Belle stood in the row, apparently waiting for her. When she spotted her sister, she beamed and nearly ran over to her, before she remembered that she was supposed to stay on her spot. "Hello Rarity!" she happily shouted at the approaching unicorn. "I'm glad you're finally here."

The mare could believe that. The filly didn't let it on, but if the fluid that dripped between her hind legs was any indication, she was in a similar predicament as her.

"Good day, Sweetie Belle," Rarity replied. "I hope I didn't let you wait too long." She tried to not make it obvious herself, but it was hard to look at the filly without succumbing to the urge to rut her right now.

"It's... It's not too bad," Sweetie replied, not very convincing. "I had to sent some... interested ponies away, because you weren't here yet."

Rarity mentally apologized to all of them. It had to be terrible to have a foal like her on the platter and then not being able to eat her up.

But here and now, she was more concerned about herself and her cock that yearned for the pussy of the filly. "Could we begin please, Sweetie?" she asked. "It might be selfish, but I have... needs that need to be quenched."

Sweetie looked at her hard shaft, which only made made it throb even more. "Oh... Yes," she answered. "I'm kinda like that too." She turned around and lowered herself, raising her butt up in the air.

Rarity gasped, as she saw her sister's sweetest spot. It was slightly open, as if it asked to be filled, and a clear fluid leaked out, like juice from a ripe fruit. A part of her, as a mare who didn't have a penis normally, wanted to lick up that tasty pussy. But they weren't supposed to do that and go straight for the "main course", as to not hog the foals' time too much. Besides, her new organ was really needy now.

Without further hesitation, Rarity mounted her little sister. They both gasped, as the tip of her cock brushed against Sweetie's moist nether lips. That only drove her on more and with a slow, but certain, thrust she parted them with the cock head and sunk her length into Sweetie.

It was still strange to her, as she never really had sex like a stallion before. The day before, Twilight showed her how to do it, but it was only one time, and as a full-grown mare, the alicorn wasn't as tight as the filly below her.

Sweetie's body resisted strongly and the fleshy walls pushed hard against the head and shaft, as her cock sunk deeper. That, combined with Rarity's inexperience with her cock, made it hard to endure the pleasure that went through her member and she approached her limit fast. The squeaky moans of the filly, that rang in her ears didn't help at all.

But she soldiered on and pushed deeper. As she got more used to it, it made it a bit easier to resist the urge to just let it go, but it still couldn't prevent the rising pleasure. Rarity was glad, when she finally reached her goal and the tip hit a barrier deep in Sweetie.

The filly gasped and looked behind her at her sister. "I-Is that..." she began, trailing off.

Rarity didn't say anything and just nodded, smiling down at her. Behind that wall was the chamber that, hopefully, would house new life.

The mare knew that the next thrust would be her last. But it was alright.

She pulled her hips back a bit in preparation, only to push forward again with a single fast and hard thrust, accompanied by a loud moan. As expected, it stimulated her cock so much that she nearly instantly came, but before she emptied her balls into Sweetie, the head already breached the cervix and shot loads of fertile semen into her womb.

"Ah, I can feel it!" Sweetie shouted in surprise, as her sister filled her up. While it was not enough to drive her over the edge, it aroused her, making her moan a bit more.

Rarity tried to squirt out as much cum as she could, but soon the jets of semen became small drips until barely anything came out anymore. The mare couldn't help but feel disappointed. It was bad enough, that she lasted so shortly, but that wasn't really the point anyway. However, at least, she wanted to give her sister more cum than that.

...No, it was not over yet. She couldn't let such a setback prevent her from pleasing her sister and giving her a better chance for a foal. And if she had to force her cock to stay hard.

Rarity pulled her hips back a bit, letting her cock slide out slightly. Only to ram it in again. Sweetie yelped in surprised, as she thought that she would pull it out completely, but didn't complain.

Repeating the motion, the mare began to fuck her little sister again. It was a bit tricky, as her cock wasn't as stiff as before, but at least Sweetie's pussy wasn't as resistant now. In fact, it's tightness helped greatly to stimulate her cock, assisting instead of hindering her.

And Sweetie was helping too. As her own arousal grew, her moans became more lustful, while still staying squeaky. After a while, she hung out her tongue, while saliva ran out of her mouth. Rarity never saw her as horny as that and she watched her quite a few times, when she was pleasing herself. Maybe she should fuck her more often.

When her cock was finally fully erect again, Rarity went all out. With full force, she slammed into Sweetie, pounding her pussy as hard and fast as she could. Both sisters moaned nearly in unison with every thrust.

"I-I..." Sweetie stammered with a hazy voice. "I'm... about..."

She didn't get further than that, as she let out a loud moan afterward, while her body spasmed and the walls of her pussy tightened around Rarity's cock. This also brought the mare over the edge once more and with a final thrust, she broke through Sweetie's cervix again, just in time for her cock head to eruption and squirt many jets of cum into the womb of the filly.

It was much more this time and, together with the previous semen, strained the little body. Under the load, it stretched quite a bit, creating a small, but noticeable bulge on her belly.

Rarity breathed heavily as her orgasm subsided and she shot the last drips of semen in her. But she felt happy and even a little proud. There was hardly a way her sister wouldn't get pregnant from that.

Sweetie's breath was raspy too, as she recovered from her own climax. She felt a bit spent, with her womb full of semen, but it was obvious that she enjoyed it.

They stayed like that for a short while, but then Rarity climbed down from her sister, pulling her cock out. It softened quite a bit and Sweetie's juices glistened on the shaft.

"Oh my." A voice behind them suddenly said.

Rarity quickly turned around to see Cheerilee standing there. She also had a cock, that seemed to be wet too and covered with white stains on the tip.

"It seems like you... really made sure that Sweetie Belle gets pregnant from you," the teacher remarked, looking at the filly's belly.

Rarity chuckled uneasily. "Well, I can be rather... dedicated to my dear sister."

"I can understand that," Cheerilee replied with a smile. "If I had a sister like her, I probably wouldn't be able to resist her too." Turning to Sweetie, she added: "But I think she could use a break from the 'generosity' of her sister. Right?"

The filly blushed a bit at that. "Yes... I think so..."

"Alright, then you can rest for half an hour," Cheerilee concluded. "If you'll excuse me, I'll have to watch over some other foals."

As the teacher went away, Rarity turned to Sweetie and gave her a small kiss on the lips and said: "Well, make sure to rest enough. There will be other ponies, who will want to fill your little womb. As for me... I think I will visit some other foals."

"Alright," Sweetie replied, smiling. "I hope you'll have fun. We'll see us later!"

As the two parted ways, Rarity considered where she should go next. The day was still long and there were many foals to choose from. It wasn't easy to make a decision.

She wondered if Filthy Rich was done with Twist...
