A Lusty Downpour
Finally, Cloud had found a pool all to himself.
He needed the space and more importantly, to not be disturbed. For a Pegasus like him it was especially important to be able to stimulate his body in complete comfort and without any distractions. Usually this meant a large closed off space, but on this occasion he had been lucky. A huge outdoor pool was part of the house that belonged to one of his closer friends who had asked if he’d be free to house-sit over the weekend whilst they were away for work. It was a secluded spot, the pool positioned in the rear garden that ran onto a deserted beach with the house miles from anywhere. The ideal place for some self-induced hyper pleasure.
He was wearing very simple attire that he knew likely wouldn’t last long with the growth he was hoping to achieve. A simple yellow bikini covered his rather generous breasts. In fact his whole physique somewhat leaned towards a more feminine look. The stallion also sported a generous and wide set of thunder thighs that were hardly covered by the lower portion of the bikini but currently flaccid between those large thighs was his hardly hidden cock, that was pushing the strings of the material trying its best to cover it to the limit. His red body jostled as he breathed gently, finally able to fully enjoy himself for the first time in days. To say he was pent up would be quite the understatement. A mere thought might set him off, in fact as his mind dwelled on the enjoyment he was about to give himself, he felt the strings of the bikini bottom tighten as blood pushed downwards.
Sitting himself on the edge of the pool at the top end he took one final cursory look around to ensure no other souls were about. It was a bright sunny day, he could feel the heat of it beating against his skin as he cooled himself off by dipping his two legs into the water of the pool. As they submerged he felt another twitch down below. He was pent up, even the feeling of the refreshing water was enough to make him excited. He leaned back a little into his huge ass cheeks which rested gently at the pool’s edge, making a rather comfy seat for him to sit on as he felt his huge sloshy breasts press against himself while he leaned forward. Already feeling stimulated, his familiar black cock rose between his breasts as making him grin ever so slightly. Usually he’d lean around himself and start rubbing, but why do that when he had something much softer resting on his chest that would make the experience so much more gratifying?
He made sure to grip each side of his breasts firmly, but not so much so that it made him feel tense. He hadn’t even started but he took another moment to observe his size, already he was too big for some auto-fellatio. Not that it mattered, today’s fun was all about growth. The pool was very large, but he was sure he could fill it and maybe even a little more than that as well.
The start of it was gentle, he didn’t want to overstimulate himself too quickly and have it all be over in a matter of minutes. That was the trouble with being pent up and denying yourself a release for several days, oftentimes he’d find that the enjoyment was just so overwhelming so fast that he didn’t even have a chance to reach his full size potential, sloshy and full balls releasing a torrent of pleasure that was lovely to experience. But he always felt a little like it was a wasted opportunity for more fun and maybe some property damage. The thought made him chuckle, he had lost count of the amount of times his monster cock had grown to such proportions it had destroyed something. Generally it was something that belonged to someone else, he was forever paying out to have things fixed.
He sat by the pool, continuing to use his breasts to massage his cock that was now erect. The feel of his soft breasts against his shaft was wonderful, the stallion letting out a small moan of enjoyment as he felt the material of the bikini tighten once more. This time however it was the part covering his boobs, they were already starting to grow with the stimulation, getting larger and pressing tighter against his shaft which was feeling more and more intensely sensitive as the rubbing continued.
At that moment he felt something else touch the water, with the start of the stimulation his ball sack had started to fill with cum, readying itself to not only release what was already there that had built up over the past several days but now filling with more to make that release at the end even more satisfying. With so much weight pulling him forward towards the pool of his balls, breasts and cock he was glad he had that immense counterweight of his ass to stop him falling forward into the water completely. He’d be able to push himself in, when he had reached a sufficient size…
Cloud continued to rub his breasts, he could feel them growing, swelling and already pumping up to a much more enjoyable size as was the rest of him. Once he started his whole body began to just get bigger. He wouldn’t say it was ballooning or blimping, he always felt heft to it. Something about his physique drove a pleasure response that meant everything just enlarged when he was stimulated. At least, all the parts that felt the effects of stimulation anyway. Whilst he was a stallion and had everything you’d expect to find on any regular bodied male, he found it particularly lovely to have some attributes of a mare as well. The colossal breasts and wrecking ball buttocks were always a part of him he particularly enjoyed and made good use of. It made him smile sometimes when he’d be with a mare and they’d comment his assets were larger than theirs.
As he continued his train of thought his heart was beating faster, his body now well in full on pleasure mode. Luckily his body had a sort of limiter too, he could through varying factors like size and satisfaction stop the growth, but generally that only came when he was ready to release.
He was a good size now too, about double as big as when he began. More continued pleasurable gropes and rubs of his expanding shaft between those growing breasts meant he kept on pushing more of him into the pool. Already a large portion of his balls were starting to submerge in the water, the feel of the warm water against the cum building up inside him was rather soothing. Another enjoyable pant of pleasure left his lips. The bra was starting to give way as the incredibly tight and stretched string could hold back his puffy breasts no more. He always made sure it was just the knot holding it in place that gave way, having ruined too many of them beforehand the stallion was rather experienced in making sure his clothing now stayed in fact, although sometimes it was fun to destroy a cheaper pair. As they gently left his breasts and floated down in the breeze into the water he made a mental note to retrieve them from the bottom of the pool later. Now fully exposed, he continued to take full advantage of his lusty growth spurt.
There was always something he felt about giving yourself a pleasurable boob job to masturbate such an enormous and throbbing cock, eager to spill its load at the first opportunity he would give it to. Hands did the job fine, but they just weren’t as soft and supple as a nice pair of breasts that did an even better job. Although he knew that his two ample ass cheeks acted as a rather good counterweight to keep him balanced, they did as well. The more they grew and filled with milk the heavier they became. At a certain size he’d just have to rely on thrusts from his own body to finish himself off with, but for now they were still easily movable to massage his cock with.
Every stroke from his breasts pumped more pleasure around his body, now sure he had enough of a size to float on the pool water, Cloud gently pushed himself off into it, leaning forward so that his breasts and cock were partially submerged. He only filled a quarter of the pool so far, but it always amused him to see that his body was so voluptuous the water started to quickly lap over the side as the displacement meant it was now too full for it to all stay contained within the structure. As he continued to grow, more of the water pushed out and ran off over the edge and down onto the beach below. A convenient run off point.
Now floating on the water, the only part in contact with the side still was his towering ass which was starting to rise above his head. The wings that sat folded on his back were now useless, he could possibly lift himself up slightly above the water if he put in a lot of effort, but he’d rather focus his attention on continuing to grow and fill as much of the pool as he can. As more of his body made contact with the water, the sensation made his body tingle with excitement. If his body and head wasn’t already red, the rosy red blush on his cheeks would have given away more of his enjoyment at his size. He felt his balls push up against the wall of the pool under the lapping waves, now so gigantic that the only position his legs could maintain was a wide spread as they forced them to the sides, looking for more space to fill with cum.
Another event in his expansion made him coo in pleasure, his areola on his breasts, now bigger than his head made contact with the water. The heavy weight of them pushing downwards into it meant that they had now gotten to the point where they were so heavy and milky that they were making their presence in the pool more known. He could still stretch his arms around his overblown breasts, but using them to masturbate himself was getting harder and more of a chore. No matter, his own body was now making up for that by simply its size alone. He wanted more, more of him to pleasure and enjoy. The bigger he was, the greater and more sensual the release of that cum river would be. He leaned into himself and with a little effort, started to thrust forward against the pool.
He had done this before, it was always a gentle balance to stop all the water from leaving as being too rough and too vigorous would mean his massive size would generate enormous waves. He remembered once a rather intensive and brisk session (which, to be fair, he hadn’t had a release for a week and was desperate for it) meant that he had emptied the entire pool of its water supply and finished up filling it with his own cum instead. The owner was not happy, he had a plan to avoid such a thing this time.
Everything around his cock though felt so...good. The act now of just grinding away on himself meant he no longer had to use his arms to give himself a boob job, his whole body was jiggling them about for him. Maybe he could come up with something like auto-fellatio to describe it but using your own breasts. A thought for another time, not now while he was right in the middle of taking advantage of such a magnificent body.
Still he grew, Cloud was almost now unrecognisable as a pony. The pool was dominated by cock, breasts and ass as his will to get bigger and bigger pushed his body in every direction it could greedily take to fill up the space. Another shiver was sent down his spine as he felt his breasts start to brush against the side of the pool, now so wide they began to occupy the space on the left and right of him, it wasn’t long before the underside of them followed and made contact with the bottom of the pool. Impressive seeing as he had started himself off at the deep end. The tightness he felt as breasts and balls, now being somewhat constrained by the space available was intense. He was sure his massive, sloshy cum filled balls would have broken out of the pool if they could, but they were being weighed down and kept in place by a set of vast butt cheeks that apart from his shaft, were now they only things that really had free room to expand being outside the pool itself. For a mere second, a thought flashed of what had become of the bikini bottom. He remembered feeling a tightness there and then it went. Probably given way and vanished into the water like the bikini had earlier.
Pants were now starting to frequent Cloud’s lips, he knew he was starting to get close. It was when the feeling of growing started to overtake his mind. Thinking about how huge he was just added to the arousal he felt.
“T-The biggest...oh g-gosh, I’ve nearly filled it...I’m sure...I can j-just about see over my h-huge breasts...s-so big...s-so sloshy...C-Cloud you’re gonna fill the pool with c-cum again if y-you’re not careful…”
The bigger he got the more he could feel the sun beating down on his body, it wasn’t heating him up per se but he did feel hot himself. But at this size, thrusting a gargantuan shaft such as his took quite a lot of effort. But Cloud was now so gripped by the thrill of his size that mentally it would have been quite taxing to stop himself. Shaft now touching the floor of the pool he had one final thing he needed to do to ensure that he didn’t make that same mistake of filling it up again, there was still quite a lot of water left despite the fact his now huge, shaking body had mostly filled the space. More pony than water in the pool, he loved the feeling of the water against his skin and wanted to retain it for as long as he could. When he felt the tip of his cock touch the end of the pool he knew he had to give one almighty thrust to achieve what he needed to do.
“Hnnggg! A-ahhh~”
It winded him nearly, in fact he had to stop thrusting for a moment to catch his breath but with one large thrust and minimal damage to the edge of the pool he had successfully pushed the end of his cock upwards enough so that it was now sitting over the edge. Luckily next to the house was a runoff down to the beach, although he was expecting more of an explosion than a dribble, a vast shot of spunk that would shoot for possibly miles if he was aroused enough. At his size he was sure he was.
For the lusty, busty, pool filling Pegasus it was all just getting a little too much to keep contain.
“F-Fuck...n-not yet…”
He bit his lip and tried to hold it back but with this much arousal it was impossible to not at least let go of a little pre, which spurted forth and splatted onto the sand of the beach with a rather unceremonious noise as he leaked a minimal amount of his pleasure forward from his dick. Absolutely rock hard and wanting nothing more than to really let go he started to thrust more vigorously, he could last maybe another few minutes at this pace if he really tried to steel himself and mentally was strong, but that was never Cloud’s forte - why be so disciplined when you had so much of yourself to take advantage of and enjoy?
Another factor was his positioning and why he loved pools so much as a way to release and get massive in, it wasn’t just the water. It was when he got to a huge size just how everything constrained him. Only his vast flank was free to expand, giant wobbling cheeks which he could somewhat grip with his spread rear legs drove him wild. Beneath this he could already feel his bulky balls pushing hard into the tiles that stopped the water escaping from the structure. Add to this big milky breasts that almost straddled his massive shaft and it was a cocktail that meant he could achieve one of the longest and most pleasurable releases that anypony could experience. He never questioned it, only enjoyed it to its fullest extent.
Beneath him the sloshing sound his balls made when preparing to release their load got more and more intense. Cum eager to escape its fleshy prison, all he had to do was let it go.
“F-Fuck...s-so huge...s-so massive...biggest...cock...breasts...ass…” were Cloud’s final thoughts, before an almighty scream of enjoyment meant that his balls could no longer hold his gallons of cum any longer.
“F-Fuuuuu- a-aaaaaaaaaaaaahhhhhhhhhhhhHHHHHHHH!”
It was...amazing, it always was. But this time he was sure it was the biggest he had been and still managed to stay somewhat in the pool. As a literal torrent of cum shot out the tip of his shaft he felt waves of water crash against his body due to his increased thrusting to push himself over the edge. He felt his body dip slightly as his balls began to empty their payload, but luckily those huge breasts, now lactating as well kept him afloat in the water.
After a few seconds of closing his eyes due to the potent discharge of cum, he opened them and saw he was still spilling his load, body almost locked up from the sensation of intense bliss and contentment he was feeling all over. In the midst of it all though, he managed to push forward with a few more pleasurable thrusts that meant he came more times, each cumsplosion more and more intense as with each one, his balls emptied themselves further of more love juice each time until with one final thrust, his massive quaking balls decided they were going to empty everything that was left and with a final scream of pleasure, a jet of milky mixture shot high into the sky and landed somewhere out of his vision off into the far distance. Thank goodness he was alone, the damage from this one would have been tremendous - he was sure he had broken some of the tiles around the pool in his final, untamed and passion filled thrusts but no matter. They could easily be replaced.
It always took him time to gather himself after the release, he spent a good half an hour simply laying on himself panting. The growth had stopped, but Cloud still remained completely erect and at the final massive size he had managed to drive himself to in the moment. The only thing in fact that had reduced slightly were his balls, but he could still feel beneath him they were already refilling. With a libido like his, he’d be ready to take full advantage of himself once more in a matter of hours. Perhaps he wondered this time if he should just stay in the pool and instead of let himself reduce in size back to normal to keep this already massive figure and get a head start so to speak. It was an enticing thought, he had plenty of room to expand out to, miles of beach around him and nothing but a whole afternoon to really grow? Why not.
In the meantime, he still had to take in everything he had felt. Every thrust, every enjoyable spurt of cum that had shot off far into the distance. Cloud wasn’t usually one to let go of a lot of pre, but as he observed just in front of him, leaning over those massive breasts he took notice of a small river of it trickling off down the bank towards the ocean. Perhaps he had been releasing and hadn’t noticed, thinking it wise to make a mental note that next time he’d try to keep more of it back so he’d get more out of the actual releases so to speak, but with already having a head start this time around he was sure he’d be able to do it.
For now, he just basked in the glory of the afternoon sun. He felt it still beating down on his body, it was a rather pleasant feeling and with his rhythmic breathing he made sure that his heart rate slowed enough so he wasn’t getting so excited again right away. He did want to make sure that his balls would be able to fill with even more cum than last time, a tall order seeing as that was several days worth - but with the spur of pleasure he was sure they’d refill even faster than last time and with even more too.
There was something about not being able to move due to being so massive that was appealing as well. With his pool filling breasts and an ass that was now towering over the top of his head behind him, he was starting to get those feelings again. Clearly his body felt it because after the release, his cock was still fully erect. Mmmm, did he really have to wait? He was sure his body could prepare more cum whilst he toyed with it, paid it the attention it deserved. Oh why not, not that the stallion could help himself…
As his shaft grew, now more than halfway out the pool and his leviathan breasts easily started to exit the pool he tried to make it so he didn’t get so large he’d start to damage the house he was supposed to be looking after, but already he could feel himself start to press up against it. Oh dear…
This was new and well, interesting. Usually it did take time for him to refill, but already he could feel his balls were bigger than before, now even starting to push his ass up further as they too started to push out of the pool. He could already hear cracking as the tiles of the pool started to give up the ghost. Looked like that property damage was starting to get more and more inevitable as feelings of lust overtook him again.
“F-Fuck Cloud...d-don’t break the house...y-you can’t afford it...b-but...bigger...BIGGER.”
Thoughts occupied his mind of nothing but size, he was so huge. Absolutely mountainous now, in fact he had gotten so large that he hardly noticed the audible CRUNCH as the entire house was crushed under his right breast, the left one now flopping onto the beach and starting to make contact with the ocean.
But his cock, he was running out of words that aptly described how huge it had gotten. The pool was now a thing of the past, in fact he hardly felt it beneath him. The Pegasus’s monster cock now stretched for what felt like miles along the side of the beach, with that release once more getting closer...closer...closer!
The final cum eruption made him scream out in pure ecstasy, an ocean of thick, white milk pouring forth which was enough to turn a large portion of the land into a cum ocean. He didn’t even need to thrust himself anymore, not that he could - his pure size was enough to make him let loose everything he had once more. No pre this time either, just pure white milky enjoyment that shot forth from his cock and two breasts. A cataclysmic cumsplosion that he had never achieved before of such an immense size. It would take him days to recover from it, he had never felt such lust and pleasure before from anything he had done.
And all he wanted was to be even bigger.
