Hard as a Diamond

A loud, wet splattering sounded through the carousel boutique as Rarity filled a condom with more cum, who was still asleep. Whatever spell she'd been hit with the other week (and her own casting of it) had changed her siginificnatly. She found herself horny all the time, even when asleep. And she never stopped making cum. Ponies around town had noticed now, but they didn't seem to mind, and she enjoyed the attention. After casting the spell on Fluttershy, the small mare became very recptive to Rarity's new hobbies, and eagerly joined in. Rarity hoped that casting it on others would do the same, and was eager to try, but she wanted to take her time. She wasn't quite sure how she knew how to cast such a spell, but it was a wonderful thing, and in using it, allowed her to fill up her storage basement, which she could then have drained and sold for a pretty penny. She now had more time to herself, now that she didn't have to take on large orders all the time to bring funds in. She'd also been experimenting with it, making new versions of it that worked in different ways. And she made a new hobby of cumming into condoms whenever she could, and wherever she could. She couldn't actually pleasure herself in public just yet, but filling condoms with pre as she sauntered about town, and replacing them in front of others gave her a thrill.

Another loud sputter of cum sounded out as she pumped out another orgasm. She smiled softly, bucking her hips as she pumped out seed. Rarity had cast a long lasting, low intensity version of the spell on herself just before going to bed at night, just to see what would happen, and made sure she wore the largest, stretchiest condoms she could buy to keep from making a mess of her bedroom. That night, upon getting comfortable, her balls sloshed and gurgled, before orgasming into the condom, filling it with over a gallon in an instant. She fell asleep to the soothing sounds of her gurgling balls, allowing her gentials to do as they pleased, leaking and cumming for the next eight hours, slowly filling the condom with gallons and gallons of cum. By the time Rarity woke up, her entire room was filled. A grin appeared on her face, and she sat up to admire her work. The condom had streched and filled every part of her room, and reminded her of a waterbed. She pursed her lips as she grabbed hold of that idea. Cumbeds could be very profitable if she could find the right kind of material to hold it in. Perhaps that stuff Twilight just made, which was so incredibly thin, it was like it wasn't even there, so you could feel whatever was in it, and highly pierce resistant...

Rarity smiled even greater as she ran through how she could go about this. Grabbing the teleporter rune from under her pillow, she charged it and sent the cum into her basement, and then balled up the streched rubber and set it to the side, to be recycled later. She made her way to the bathroom to freshen up for the day, brushing her mane, tail, and coat. She grabbed a bottle of Bouteille de Sperme, shaking her head at it. It was a little silly, naming the lotion Bottle of Cum in Prench, but she supposed that's what it was. Pony cum was incredibly magicaly charged, and had a wide array of uses if properly treated. She'd actually ran out of that particular bottle a while back, but after some research, she found that making her own wasn't all that difficult, and simply refilled it than buying more.

Pony cum, infact, could be used for most hygiene products, and with some work, a unicorn could pretty much make their own lotion, shampoo, and even toothpaste, provided they could produce enough to fill everything, which Rarity was most certainly capable of. As she ran out of things, she started saving the bottles, and replacing them with her own recipes, a tingle running through her body as she rubbed her own cum all over her body, and in her mouth, in order to freshen up for the day. Alot of recipes asked for various, powerful perfumes and such to help mask the smell of cum, making it expensive for one to make their own for profit. Rarity, however, loved the smell of her own cum, which oddly enough had a slight grape flavor to it. And the reactions of those around her as they smelled her were absolutely wonderful.

Feeling fresh enough to head out side, she stepped through the puddle that had formed on the floor, heading out of the room and down the stairs. Rarity's shop wasn't open as often as it used to, as it seemed her public nudity had started a new trend in Ponyville, most going without clothing entirely now. Not that it mattered, she was well off enough, and it gave her time to design at her own pace. Ponies had also started wearing condoms more often as well, even though most of them didn't need to. She had even been approached by an official spokesmare of her favorite condom providers, offering her a wonderful deal on them in bulk, as well as an absolutely adorable little handbag-of-holding to hold them all, as a gift for all the business she'd been giving them.

A large basket was found next to the door, filled to the top with condoms, holding at least a gallon each. She'd just been making so much lately, and she was the Element of Generosity after all, she thought it'd be nice to give some of the -ehem- overflow as free gifts to anyone who came in. She walked around the store some, admiring her new flowers, before holding her cock up and placing the tip on the rim of their pots, and letting pre leak into them. Specially bred flowers, designed to gain nutrients and moisture from pony ejaculate. It was odd. Public sex and the like were frowned upon, and even illegal in some towns, but cum was an important and widespread substance used in most everyday things, and leaking fluids and filling condoms in public where jsut fine. Almost all food in restraunts had some cooked into it, or used as a sauce, and plants, like these ones, were designed to use it in place of dirt and water. Rarity hoped that someday, she could get rid of the social taboo, and make these thing even more widespread. She liked the idea of a fountain in the town square, filled with with cum that ponies could use and fill as they please.

It was sunny out today, so Rarity donned a sunhat and a slim pair of sunglasses. Tugging on another condom, she made her way out the front door, and locked it behind her. She cast a quick spell on herself, a less intense version of her new spell, before taking off to Twilight's Castle. Her condom quickly filled as she sauntered along, pulling the gazes of any mare she happened by. Once it was full enough, she pulled it off, tied it, and passed it off to the mare closest to her. Ditzy Doo beamed brightly, untying it, and guzzling the treat, before sliding the stick condom onto one of her own cocks. Rarity giggled lightly at her antics. She loved the odd marely a great deal, and enjoyed watching her do odd things with her cum. She had a pair of mismatched cocks, and a sheath and balls the same color as her coat. One cock on the mare was a good two feet long, and the same golden color as her eyes, and a dark yellow splatter coloring it. Her other cock was one foot nine, and the color sceme was inverted. Rarity loved that about the mare, and had always wanted to design something based on it. She leaned into her ear and with a whisper, invited her to the Boutique at a later date. Derpy grinned happily and nodded her head, cum flicking off her face as she did.

More condoms were filled and replaced, passed off to those who wanted them. By the time she reached the castle, she counted sixty nine condoms filled, each with at least three gallons of cum. A new record for her, and such a silly number too. She pushed aside the large door, and made her way in.

"Twilight!? It's Rarity! I just had a wonderful idea that I wanted to share with you!" Her voice echoed through the crystal halls. A second later, there was a bright flash, and Rarity found herself in Twilight's lab. she held her head for a moment as the room spawn from the suddenly teleportation.

"Hello Rarity! Oh, sorry about that. I was busy and didn't want to leave yet," Twilgiht stood in front of her, completely nude, and both cocks erect. Taking a look behind her, Rarity saw many oddy shapes of cum, moving and flowing around, but held in verious shapes but what looked like nothing. Twilight had been busy it seems. The whole lab was filled with the smell of musk.

"It looks like you've been busy with your newest creation darling. I actually wanted to talk to you about that," Rarity went on to explain her idea for cumbeds. omething that could be filled easily, simply stick a ball of it on your cock and cum, or fill it with stored cum. It would look like a pool of cum shapped into a bed, and the smell of it would permiate the room. Perhaps an additional enchantment that could allow one to shove their cock into it as they pleased without damaging it. Twilight set to work, grabbed a tub of the Invisemen, as she called it, and enchanting it. She made several balls of it before finishing, and offered one to Rarity.

Rarity accepted it, pulling off her condom, and sliding the odd ball onto her cock. It felt odd, almost like there wasn't anything there at all, and yet a warm, soft feeling encompased her length at the same time. Twilights horn lit up, and Rarity felt a pleasure unlike any other in her cock, and came instantly. Cum rushed into the ball, filling it out quickly, and the substance seemed to dissapear as the cum took the shape of a bed. Once full, Twilight pulled it off Rarity's cumming cock, and placed another, filling it quickly too. Rarity, in her lust, cast her spell on Twilight. The effects took hold quickly, and Twilight lets out a loud moan. Her mind is suddenly filled with lust, and her balls explode outwards, reaching a foot wide each in a second. Cum blasts out of her cocks, coating everything near her in it. She makes her way behind Rarity, and lines up with her wet pussy, before pressing forward, one going into her pussy, the other into her anus. Rarity gasps, and cums harder. Twilight switches another one onto Rarity's cock, before roughly ramming her cocks into Rarity, balls deep, creating a massive, two cocked bulge in Rarity's stomach. She then pulls out as far as she can, and slams in again, falling into a rough, fast rythme. Rarity's breasts bounce wildly as she's fucked, her balls growing quickly, and her cock putting out more and more cum.

Eventually, all the beds are filled, and Rarity's cock is let free, spraying cum all over the lab. Her stomach is expanded greatly, looking like she's pregnant with a full grown Alicorn, and cum blasting out of her mouth and nose. Twilight continues to pount away as hours go by. A door opening to a massive vault connected to her lab, also meant for cum storage, and filling it up with cum. Twelve hours go by, before the cum stops. The vault is filled completely with cum, so much so that the room they're in is filled up to Rarity's breast. They make their way to the stairs, dragging massive testicles on the ground. After a tight squeeze with their balls, they find themselves Overlooking several more cum vaults under the castle. Twilight closes the door, before grabbing Rarity, and ramming into her again.

"With that spell you've cast? I've only just begun."
