Hard as a Diamond

In hindsight, she maybe she have stopped after the first few orgasms, but it had felt so good, and her sister moaned so adorably, that she couldn't help herself. On the bright side, she had helped her 'little' sister through her first heat, and develop into a wonderful, and very large mare. It'd been a week since then, and by the time Sweetie's heat had finished, she stood at just under eight feet tall, and a foot and a half long cock, with balls as big as her sisters. Her breasts were a couple inches smaller around than Rarity's, and every curve of her body had filled out well. Though her heat had finished, she was still growing some, and would likely grow larger than her sister within the next few years. She had lost control of herself, but Rarity didn't mind. It had felt nice to let go, let her lust take over and unload herself in somepony else. In fact, she wanted more. So much more. Normally, in public, she was reserved and quiet about sexuality, keeping her lust hidden beneath a mask. But after Sweetie walked in on her, that masked had cracked, and was falling away.

Her shop was closed today, and she had finished all her orders, so she had all day to do as she pleased. She woke up that morning, nude in her bed as was usual. She moved around a bit, giving a big yawn, and stretching, before she reached down to gently stroke her daily morning wood gently, smiling at it. Her cock gave an appreciative throb at the attention, painting her chest with a nice rope of pre cum, making her moan softly. Smiling more, she then grabbed the member with both hands, stroking it lovingly up and down, making it respond eagerly, sputtering out pre cum in fat ropes all over her belly, chest, and face. She was extra sensitive and incredibly horny that morning, it seemed. It only took her a few minutes of this light play, before she felt her orgasm approaching, the massive load of cum running up her rod, before blasting out a fat, heavy, warm rope of cum directly into her face. She only had a moment to gasp some, before another fat rope filled her mouth and splattered her head board. She happily swallowed it down, just in time for another load to gush its way out of her cock, spraying against the wall as she moved it away from her face. It takes her a good, long half hour of painting her room with hot, thick ropes of cum to finally calm down from her orgasm.

She sat up in the bed, panting hard as she observed the mess she made, smiling as cum dripped off her face. It was a beautiful sight, her cum coating everything. She very much wished she could do this to everything... cum was a beautiful, wonderful sight to behold, in her mind, and everypony deserved to be covered in it all the time, if only...

"Oh goodness, so much~ and it seems my darling cock is still up for even more~ Today looks like it could be fun" She giggles some, lust floating in her mind some as she crawls out of bed, and begins cleaning up. A simple affair, really, with her special cleaning spells. For herself however, she decides a good long bath would would, and slowly saunters into her large bathroom, idly stroking herself off on the way, leaving a trail of cum as it eagerly throbs.

She stood before a series of body mirrors to stare lovingly at her cum coated body. What she found was truly divine, her beautiful cum soaking into her fur, which is what made it look so nice and soft. Her cock, a massive, regally colored beast, twitched between her legs, growing erect once again as she spent time admiring herself, before eventually, she couldn't take it any longer, and took it into her hands, slowly jerking off, as she watched herself. Within moments, she came once again, painting her mirror some, before she lifted the beat up to point upwards, sending cum up to the ceiling, before it comes raining down on top of herself.

She'd never been so sensitive and full before, nor came this much, this many times in such a short period of time... but she was absolutely loving it! Maybe, if she tried hard enough, she could... no, she needed to take a bath first, and get on with her day. She left the mess she made behind, to find her large tub, looking at it curiously. It was a very good tub, with special made drains, just in case she leaked a little too much in the tub... but with lust drowning her mind currently, she had some very different, fun ideas of how to put those drains to the test.

She smiled to herself, as she took her cock and pointed it directly at the tub, and began pumping it eagerly, making it bounce around flinging cum all over, letting out long, pleasured moans as her orgasm washes over her effortlessly. Her cock began pumping out rather large loads into the tub, filling it rather quickly with cum. It didn't take long for her to get a nice, warm cum bath going, and smiling at her work, she crawled in to relax... and it was absolutely divine. Just the feeling of the hot, thick liquid swirling around her is enough to drive her to orgasm again....

It was a nice day out, and after making a rather large mess of her bathroom, she decided to wear something nice, a simple blouse, a long skirt, down to her ankles, and a big, stretchy condom for her very leaky endowment, to prevent making a mess everywhere she went...as well as a handbag full of spares to last her the day. She'd always been a messy one, but with the constant state of arousal she recently found herself in, it seemed to have gotten worse.

After getting herself ready for the day, which involved showering, dressing, applying make-up, breakfast, and at least three orgasms, she found herself standing at the door, adjusting herself a little, before straightening up, and striding out with a confident look, trying and failing to not think about how she was going to pleasure the leaky beast swinging between her legs.

There were few ponies out and about today, likely due to everypony making their way to Canterlot for some big hoofball game. She'd never been too big on sports, and decided to stay behind as her friends made their way up into the capital city. Her reasoning was that she wanted to work on some new dress designs, but in truth, she wanted to make use of the opportunity. A nearly empty town of Ponyville to serve as her playground as she went about doing lewd things in public, with almost no one to see her do so. She shuddered in anticipation at the mere thought.

So many wonderful, lewd thoughts came to her as she walked. From simply masturbating in public places, breaking into someone's home to cum on there stuff, even the thought of maybe finding Ditzy napping someone and coating the poor mare in her sleep... not that she would mind. Ultimately, she decided on rubbing one out somewhere in the market place might satisfy her for now. A smile on her face, and a restless rod between her legs, she briskly made her way in that direction.

Rarity had always been a bit of a daydreamer. While earlier in life, it was generally just about new dress designs and princesses and living in the wonderful city of Canterlot. Now, however, her daydreams were generally very degenerate, and she imagined herself with her friend Pinkie Pie, bending the plump mare over a table and pounding her fat pussy into oblivion. A fantasy that turned up the heat on her. Her cock, spurred on by the thoughts, happily drooled cum into the rubber around it, slowly filling it as she walked about. Rarity shivered as she imagined pulling on that big, fluffy tail, giving the mass of flesh that was Pinkie's ass a hard slap, dominating the lovely pink mare. The feeling of her fingers sinking into those godly cushions as she thrust herself deeper and deeper. Ahh... wouldn't that be lovely...

She finished the little daydream by completely coating the Pink Pony in her spunk, along with the entire room... and subsequently discovered that her little fantasy had the unintended consequence of filling her condom with a few gallons, and her hard cock making a rather noticeable tent in her dress. It drooped heavily and low to the ground, sloshing about as she walked around. She'd need to change the thing pretty soon, before it ended up dragging on the ground. Looking around, she found no one here, and the likely hood of anypony showing up was small.

She lifted her dress up, her hard cock standing at attention before her, and admired how much she filled the condom
