Beatin The Heat

Celestia stared solemnly out the window of the carriage, as clouds and various pegasai flew past. She subconsciously shifted her dampening rump from side to side, scratching that age old itch every time she witnessed one of the better looking stallions shoot past. The silken upholstery on her seat was soaked with a mixture of sweat and her juices, with her boiling vulva nearly dripping with anticipation. It was unfortunate then, that she was forced to attend a small gathering at Ponyville, visiting her alicorn apprentice and her friends. The carriage touched town with a sharp jolt, sending waves of pain through Celestia’s bladder. The problem with heat, in her opinion, was the constant desperation to urinate, to spread the musk of her availability. She had done so five times that morning, the boiling fluid seemingly infinite in its volume, causing the sweet scent of aroused alicorn to spread throughout her quarters.

Carefully climbing out of the carriage, she took care to conceal her throbbing vulva from the crowd as she walked over to the welcoming party, consisting of a small orange foal carrying a bouquet of flowers; Twilight Sparkle and her group of associates; and a rather ravenous looking red stallion, his well-worn bridle resting gently on his muscular shoulders, his well-built back curving into a solid rump, muscles jutting out slightly, evident of his time working in the fields. Just viewing his luscious rump caused her vulva to start winking rapidly, her pulsating clitoris flicking droplets of arousal from it as it throbbed in and out of her burning white lips. The scent of her warm invitation reached both the stallion and his sister, her eyes widening as she recognised what was happening. Celestia casually observed the underneath of his body, her eyes drifting towards his black scrotum, his two orbs churning with boiling seed as his rod began to make its way out of its warm hideaway, slithering outwards as it detected Celestia’s nearby marehood. She could almost see the tip, its sensitive tissue stimulated as it unfurled from its sheath.

Twilight was becoming more and more impatient with her long serving teacher, only attracting a nod or an “Uh huh” from Celestia as she recounted some of the more recent events in Ponyville. Fed up, she decided to move on to Sugarcube Corner, where a large feast had been prepared for the royal guest. As they left the main road, Applejack lay into her fully aroused brother, informing him of his indecent actions and sending him back to Sweet Apple Acres to calm himself down.

Celestia spied the town hall, knowing that it had proper appliances for her curvature, and not wanting to risk a painful toilet break, she excused herself from the group and dashed for the toilet. It was built in honour of herself, a large squat toilet constructed from fine stone with a decorated inlay of apples. Two of her royal guards followed, however respectfully stayed outside of the room, signalling that the Princess was present. It was just as she remembered, down to the scent of the pine that was used to build the room. Not wasting any time, she squatted over the bowl, close to the water. She held her tail to the side as she bowed her curvaceous white rump towards her target. A stream shot from her already parted lips, splashing directly into the water below, spraying droplets onto the apple inlays. A sudden bubble of gas forced its way through her rectum, passing out into the air through her puckered plump anus with a low boom. She pushed slightly on her bowels, although did not feel any major mass inside, so she relaxed again, continuing to spew urine from her luscious lips. She finally finished, carefully drawing a piece of tissue along her vulva, soaking up the remaining drops of urine that had collected behind her hot clitoris, however she wiped more lubrication than urine onto the tissue. She dropped it into the bowl, flushing it as she left to rejoin the party heading towards the bakery.
As she entered the bakery, Celestia’s nostrils were assaulted by a combination of baked delicacies and various other treats. Her tongue almost flopped out of its home as her mind began to buzz at the sudden invasion of all these delectable delights. Taking her place at the wide oak table, she engaged in some light conversation with some of the others, hoping to take her mind off the well-endowed stallion whom had sadly yet to make an appearance. The hours rolled onwards, as course after course of creative consumables was brought out for her consumption, occasionally stopping to allow her to finish ingesting the large cakes. Eventually her stomach reached its maximum capacity, forcing her to stop eating the delightful pastries, bringing her attention to another problem brewing deep inside of her engorged lips below.

She needed to pee. Again. Now. The constant consuming had deferred her attention from the issue at hand, her bladder had filled yet again to an enormous proportion, ready to spew forth the beacon that Celestia was available to be consumed by any stallion, just like the small pies she herself had ingested just minutes before. Excusing herself, she made her way to the rustic restroom that was housed in the bakery. Opening the heavily decorated door, she came to a shocking realisation. The toilet was a painfully tiny sit toilet, and whilst it was thoroughly cleaned, it would not accommodate her curvaceous rump, either forcing her to spread her legs and sit awkwardly facing the uncomfortable looking cistern, or crush her tail and anus up against it whist attempting to direct the flow of urine from her bursting lips into the bowl. No, this would not do. In a final act of desperation, at the point where her bladder was going to release its boiling hot contents whether she liked it or not, Celestia flew out the window, the excursion causing a small squirt of urine to jet form her nethers, landing with a splash on the wood below as she burst outside.

Landing awkwardly next to the rear of the building, Celestia wasted no time in scouting out a patch of grass close to the wall that would suffice for her incoming flood. Rocketing her tail to full mast, she revealed her still burning vulva, its two soft lips parted, the bright red inside coated with a sheen of lubricant, leading into an extended tunnel, its walls dripping with arousal, their ridges pulsing in sync with Celestia’s heartbeat. At the end of the deep tunnel sat a puckered cervix, pulsing in preparation for a length of stallion to connect with it and send warm white seed deep into her womb. At the junction where the two luscious lips connected poked an engorged nub of sensitive flesh, winking to the world as a signal of its desire to be stimulated. Even Celestia’s two reasonably sized breasts quivered, their nipples jutting out of their usual position, hidden behind a patch of pristine white fur. Celestia’s anus had flattened outwards under the pressure of containing several lumps of now digested delicacies, the usually firm round balls reduced to a softer consistency, due to the finer cuisine. The final piece of the puzzle that was Celesita’s vulva visibly pulsated with excitement as to what was about to occur. Drips of urine squeezed out of her tiny urethra, rolling out of her vulva, dribbling downwards to stimulate her bundles of soft breast tissue. The stream increased in strength, an audible gush flying out of her blasting urethra. The sensation was orgasmic; the combination of the relieving release of pressure inside along with the pure stimulation of hot urine shooting into her overly sensitised clitoris causing her to moan in ecstasy. A torrent of bright yellow fluid rained down onto the grass below, causing a puddle of warm liquid to quickly form. Her vagina, radiating heat, began to flood with its own mixture, as Celestia craned her neck and arched her back in the delights of her stimulation. She could feel an orgasm coming, the pressure reaching its maximum in her aching, soaking loins. Suddenly, she ran out of the sweet juice, the sudden drop of pressure leaving her painfully close to the edge. Disappointed, Celestia winked her buzzing clitoris, flicking droplets of arousal and heated piss out of her soaking vulva.

Relaxing slightly, marehood still burning with desire for release, she felt an intense pressure building behind her pure white anus. The pressure burst outwards in a loud, powerful blast of gas, the heat seemingly singeing the delicate ring as it opened a window into her pink rectum, the end of a large build-up of digested matter clearly visible whilst her quivering white rim vibrated. Every inch of her bursting intestines seemed to switch to automatic. She could feel the firm balls poking at her soft flesh as they rushed towards the puckering exit.
“Ma’am?”
Oh shit…

Turning so her explosive rump was facing the wall of the store, she flattened her tail and squeezed her anus tightly closed, the only thing left being a single ball, stuck halfway out of her. The irritation coupled with the ridiculous pressure drove Celestia to insanity. In front of her was a sight for sore eyes. The stallion she was so infatuated with had made his reappearance, only at the worst possible time. Had he noticed Celestia’s display? Shivering with fear, no sound exited her lips. Her vulva however, had other ideas. Her clitoris, still desperately aroused pulsed rapidly out of its slick hideout, all whist Celestia’s essence began to once again run out of her pulsating vagina, almost dripping from her warm lips. It was as if she had never released her bladder, her urethra threatening to spill once more. “Are ya alright, ya highness?” The stallion moved closer to the aroused mare, the tendrils of her hormones tickling his nostrils. Inhaling as he stepped closer still, he was assaulted by a different scent. The ball of digested hay and other delectable decided that now was the time to make an exit. It fell to the ground, its rich aroma bursting into the air and into Big Mac’s nose. Celestia threw caution to the wind, arching her back as her tail flew back into the air. She thrust her urine soaked hooves into his muscular chest, shoving him backwards as she began to offload her treasure. Clumps of compacted fecal balls erupted from her stretched anus. Brown lumps rolled around her hind hooves, their collective fragrance assaulting her nostrils. Big Mac, at first aghast at this sudden eruption, moved around slowly, cautiously, in order to witness the event unfolding. Bubbles of gas forced their way out, blasting several slick balls against the wall of the bakery. Big Mac’s stallionhood arouse from its short slumber, extending his thick, leathery foreskin outwards, then suddenly pulling back, revealing a pale, thick penis. His tip flared out, its bulbous end dripping with pre. Celestia continued spewing waste, the pile behind her beginning to build. The chunks of slimy matter were growing in size, each one more difficult to force out than the last. Eventually a massive lump of once delicious delicacy found its way to Celestia’s aching anus. No matter how hard she pushed, the lump refused to budge. After several minutes of pushing and straining to no avail, she felt a rough hoof between her firm breasts. The hoof pushed hard on her tender white stomach, forcing the mass out of her strained anus. The lump shot out, splattering apart as it stuck the wall behind.

Recovering from her ordeal, Celestia moved away from the pile of alicorn waste, just as Big Mac stepped over it. His orange tail shot up into the air, revealing his black anus, leading down to his scrotum, powering the massive hard on poking his stomach. His anus cracked open slowly, a burst of gas escaping as it did so. Clumps of wet fecal matter began to fly out into the pile below, trails of brown liquid flowing between the balls of aromatic matter. The scent was quite different to that of Celestia’s waste, the pungent scent of digested apple drowning out the sweet smell of broken down delicacies. Celestia stared in awe, barely noticing Big Mac’s display, her attention fully on the length of stallion meat in front of her. There was her goal.

Big Mac completed his work with a loud fart, sending droplets of liquid shit flying from his tight anus. Celestia’s pile of firm brown matter was fully covered with a soft, semi-liquid coating. He turned around, revealing the awe inspiring sight before him. Celestia had her rump facing him, tail still pointing skyward. He moved cautiously towards her. Every breath he took was laced with the sweet perfume of Celestia’s aroused vulva. Here was his dream, his fantasy, standing before him. The sensuous smell seemed to call him, begging for the cure for its pain. A cure, only he could provide. Celestia was by now fully aware of the effects that her hot emissions were causing on the dazed stallion behind, and so began searching out a more ‘Private’ place. Quickly she noticed the perfect location, a large apple tree, concealed between two seemingly empty houses. Checking behind to ensure that the fully aroused stallion was following, she snuck into the roomy space.

The area was dim, the only lighting being the all-seeing figure that was the moon. A carpet of soft grass coated the small patch and the large trunk of the apple tree blocked all visibility from behind. Celestia stood facing the wall of one of the houses, her tail rose slowly as Big Mac made his way towards her waiting pussy. Her coloured tail reached its peak, her red lips standing out against her soft, yet dampened fur. In a final burst of hot arousal, a spurt of steaming urine shot from her burning urethra, producing a cloud of sweet vapour as it stuck the cool air. The scent of her desperation was a tsunami of pure sex hormones, sweeping the dazed stallion off his hooves. Celestia turned to face him, her horn igniting to produce a flash of light, revealing a wrapped piece of rounded rubber. Carefully tearing the large condom out of its prison, she lowered herself to Mac’s under side, levitating the rubber object towards his engorged penis. Quickly rolling the device all the way to the hilt, she stimulated his tip just a bit. It flared outwards in a display of his power, testing the strength of the condom as he did so. With everything to her liking, she turned her back towards Mac, lowered her front and arched her back, presenting her awe inspiring sex to her mate. Big Mac could feel the heat emanating from the vulva before him, sending waves of powerful arousal through him, culminating at the tip of his member. Celestia’s clitoris winked at Mac, signalling him to begin his work. He almost leapt onto Celestia’s smooth rump, his rough hooves grabbing around her curvaceous hips. His rod flailed around, probing her delicate vulva for an opening. Her vagina had been dripping with lubrication for a number of hours, making it the most slick she could remember in recent history. Big Mac’s rod slid in to its cotton palace, the walls pulsing in sync with the member inside. He plunged it in until it rammed the swollen cervix blocking the end, then drew it out until it feathered at her clitoris, proceeding to plunge it back in, repeating the cycle. Celestia began to moan in pure pleasure, a well-known fact about heat sex was that, despite the risks, it was the best pleasure for the mare. Mac continued his vicious plunging of her fiery vagina, his tip raking at the edges of her steaming tunnel. Celestia’s moans increased in volume, the pleasure simply too great for her to keep it contained. The sensation of Mac’s flare rubbing against every rib of her throbbing vagina was indescribably wonderful, every inch of her mare parts virtually screaming in bliss. The constant stimulation she had received for the last hour was beginning to culminate, as she began forcing her luscious rump back into Mac every time he brought his thick rod in. Finally, in a fire of eternal primal pleasure, the sun goddess came. A powerful shot of cloudy liquid rocketed from her urethra, as her orgasming vagina Contracted around the rod inside. She slid off her ride and lay on the floor, vulva pulsating as marecum dribbled out onto the ground.

She recovered rather quickly from her period of bliss, turning to find her mate sitting in his firm rump, hooves wrapped around his still wrapped, still fully erect member. He slid his hooves along the slick rod, attempting to orgasm himself.
“No”, Celestia whispered in his ear
Noticing that his length was still slathered in lubricant, she turned her back once again, clenching and relaxing her anus to pulsate the rounded bundle of muscle. Mac, taking her hint, mounted her again, carefully sliding his slimy rod into her warm chamber that had been containing much material just a few hours prior. He found that with no real limit to how far he could insert his member, he could slide his rod in until his large balls tapped against the hot vulva below. His rod was so far in he could feel the warmth of the mushy, misshapen lumps of freshly digested matter. Celestia’s condom was worth it for both parties, and here was the proof. He began running his length in and out of her muscular tubing, the lubrication on his rod aiding the mucus inside, helping slide his meat through the contracting chamber. It was an odd sensation for Celestia, she had been wanting to try this for many years now, however a lack of a mate and cleaning issues with her prised dildo had prevented her. Every time Mac touched a slight bend in her bowel, her entire length contracted hard, eliciting squeaks of pleasure from her. The sudden invasion of her intestine, coupled with the constant waves of contraction, were causing all the wet lumps of matter at the end of Mac’s workspace to be combined together, forming a lumpy log as the liquid was slowly being absorbed from her assaulted tube. The contractions wrapping tightly around his rod along with the warm reward every time he reached the hilt of his length were quickly driving mac over the edge, with his thrusts increasing on both speed and depth. Celestia was fully on her own cliff as well by now, the odd stimulation serving as a sufficient way to quench her still inflamed lust. Mac was the first to orgasm, shooting a forceful jet of cum from his tip, filling the condom quickly, the sheer volume causing the end to bulge with his white load. Celestia was next, the sudden eruption of warmth deep inside of her successfully driving her over the thin edge. Her front legs buckled, her rear only kept standing by the stallion behind, his hooves locked around her hips as he orgasmed. He finally finished pumping the outstretched condom with his boiling seed, so he fell off of the puffing mare. His seed filled bag, however, took some effort to remove. Immediately, Celestia’s system regained control, switching to automatic as it slowly began to move the smooth log towards its exit. She quickly turned away from the heaving stallion, just as the tip of the brown mass appeared at her aching anus. It was relatively fast moving, carrying the remnants of the lubrication used to jam Mac’s rod inside minutes prior. It made a sharp crinkling sound as it increased in length, the only visible reference to what it should have looked like being the occasional clump of hay sticking out of the mass. It was almost 30cm long when it fell from its temporary crypt, bringing with it several watery balls of fecal matter.

Mac’s condom, lubricated by the build-up of seed inside, fell from his deflating dick. Not wanting to leave permanent evidence, Celestia dissolved the device with a flash of her horn, leaving nothing but a small puddle of semen, her fresh, fetid log, and various sex juices, scattered around the hideaway. She moved towards Mac, lowering herself to be level with his flaccid length, which had yet to return to its warm home. It shimmered in the moonlight, the fresh, warm seed running down it. She held it in place with her magic, proceeding to slowly and firmly lick the substance from it. The pure saltiness of it intrigued her, causing her to seek all over the meat for more. She lapped all over his tip, at one point attempting to suck the remaining semen from it. Suddenly, a jet of hot urine blasted from him, dousing both her lips and her mane in the strong smelling liquid. She shot backwards, however, it was too late. Her head was dripping with the warm substance. She playfully gave a disdainful look to Mac, unable to hold it for long until she burst into laughter. She stood back up, leaving the stallion on his back as she turned around. Raising her tail to reveal her still soaked vulva and smudged anus, she clued Mac into what was about to occur. Too late. Before he could move, a forceful squirt of urine shot from between her sweet lips, showering him in the pungent gold liquid. A small drop fell onto his lips, causing him to curiously taste it. The oddly salty taste didn’t faze him much, but the power contained in that drop told him to avoid drinking it. It didn’t take long for Celestia to run out of juice, her performance ending with a droplet of urine landing right on the tip of Mac’s nose, standing proudly before him.

The two fell into a loving embrace, laying in each other’s warmth and various liquids for a couple of hours, occasionally murmuring to each other or caressing sensitive areas. The urine dried from their backs, however the areas where they were touching were still soaked with it. Celestia decided to leave before she was missed by her guards, which she had noticed taking post outside the bakery. She gave a final memento to the drowsy stallion before her- a kiss unlike any he had received before. It seemed to contain the fires that he had cooled, the streams he had been doused in and the pleasure he had both given and received, all in one kiss. It was as if the sun was shining in the middle of the night. As she left the hideaway, she failed to notice a large stain of fresh semen on the wall outside.

Stepping outside, she was immediately surrounded by a group of her most trusted guards. They instantly detected that their master’s heat had been quenched, and, as if part of a hive mind, lead her to the carriage waiting outside the bakery, informing her that the patrons had been notified of her imminent departure. They left without a sound, flying in formation around the gold carriage. A younger recruit flying at the rear, was the only one to notice something odd. The strong smell of a stallion’s urine hung in the air around Celestia.
