Prologue: Summer Solstice's Birthday

Laying on her own bed, a much thicker and powerful version of the mare she once was, was a strong brilliant orange mare with a scarlet mane with orange and yellow highlights. Enjoying herself on a particularly sweltering July afternoon that was only exasperated by the hazy musk overtaking the room with both its potency and its smell. Though the mare, Summer Solstice, was aware that it was entirely because of her that the room was like that. And she delighted in it more than she would normally, considering that in the heat of the summer and her body’s musk, it was her birthday that she was choosing to spend her day in. It was the early afternoon, and she was doing the same thing that she started doing the moment she woke up: jerking off her fat monstrous bitchbreaker of every load that had built up in her massive balls throughout the night as she slept.

Summer had no clue that her time fucking Izzy Moonbow senseless and being sent back to her time period would follow with such a transformation. Her cock had become longer, thicker, and venier. She had a much more prominent flare and medial ring that was always leaking pre-cum unless it was left unattended too long, then it would just straight up just start leaking cum. Of course her body changes didn’t end there, with the orange unicorn developing wider hips, a fatter ass, thicker thighs, and a bigger ponut that had a more sensitive prostate. Moving her hoof up and down her fat cock with the additional efforts of a magic spell from her horn jerking herself off, Summer was getting overwhelmed by the haze to the point that she briefly channeled the energy of her horn to open the window to let out some of the musk. Making it easier to breathe, and making a small effort to keep her voice down while relieving herself, that was for naught. From outside the window, she could hear the loud feminine cries of the regular mares being fucked while hearing the all too obvious grunts of the dickmares. Glancing outside of the open window, sure enough, Summer Solstice saw that her musk had gotten the mares and dickmares outside in a rutting frenzy. Not dickmares as big as she had gotten, but still ones with fat cocks pushing the eager mares into doggy style and mating presses as they submitted to their base urges. Summer wasn’t upset with this slutty turn of events though, as it gave her pleasant background noise to enjoy her birthday jerking off more dickmare loads.

Her stronger magic and more powerful stature had a slight drawback though, having a bit of a jiggly and pudgy tummy. And instead of having her cock be properly sheathed for decency’s sake, it was out all the time even when it was flaccid, nearly dangling far enough to touch the ground. Her bigger body left her wobbling with every step, and unable to go out and about in public without being treated as a spectacle by the public. Slack jaws, wide eyes, lots of ponies giving double takes as they couldn’t stop staring. It didn’t help that her balls were making her wobble on top of her chubbier body, being extra-full of swimmers that demanded to be placed in a hungry hole. Though among the shocked looks were also mares and dickmares that would try to sneak off to a “discreet” place to jerk off to her appearance, which flattered the big dickmare. The small doorways for places such as a cafe or other local stores were unforgiving on her flanks though, causing her to shimmy her fiery orange ass cheeks inside and be met with furiously blushing cuties that had heart eyes. Though, after a glance at her magical monster, became too intimidated to approach her properly.

And with the increase in her magical abilities, her power, and her physical body, Summer noticed that it made a significant difference in her sex life. Her libido, endurance, sensitivity, orgasm time, and the quality of her cum had all changed substantially. She even had no refractory period, with the fat dark brown cock of hers remaining hard even after she had just cum. Her loads of hot white cum had become thicker, creamier, muskier, stickier, and larger than they had ever been. Leaving those fat balls backed up for too long left not only jizz leaking out after a few hours, but left her losing focus and having difficulty in being productive for her university classes if she neglected her length for even longer than a few hours, sometimes having to walk out and take care of herself to have even a bit of peace. And worst of all, if she dared go a full day or longer without taking care of herself, she couldn’t do any basic thinking or functions as her entire body was riding on a need of unreleased lust raging throughout her entire body. Her balls would be so full that she couldn’t even walk.

Summer Solstice ultimately wondered how these major changes could’ve even happened, the timing could’ve been a mere coincidence that was a major post-adolescence growth spurt. But the evidence leaned more towards her changes having to do with the time spell that caused her to end up in Bridlewood. She focused her mind on what needed to be taken care of, over and over again to properly benefit her hypersexual body. Returning her magical energy to her cock, she stroked herself off faster as she brought a nearby vibrator to the tip of her bitchbreaker.

Groaning, her blue eyes rolled to the back of her head as she savored the powerful vibrations to her sensitive and fatter tip, Summer gave in to her current fantasy. Facefucking that sweet classmate and friend of hers, that pink unicorn Luster Dawn. How innocent the mare appeared to be, her heavy blush and bitten lip as she had blatantly ogled Summer’s new body each time they sat next to each other in class. She imagined her friend’s eyes rolling to the back of her head as she gave a hungry GLK GLK GLK as Summer hilted her cock down her throat each time. Her fat balls needing to unload a dozen orgasms down Luster’s throat, they would be slapping the underside of her muzzle as the more submissive mare would moan loudly against Summer’s medial ring. As she practically felt her friend on her cock, Summer moaned as she released another geyser of creamy hot seed onto her blankets and sheets that she would inevitably have to wash at least twice just from how strong her loads became. The thick seed even coating her floating vibrator beyond what she could see, Summer used her horn to float the messy vibrator into the nearby sink in her room. With any other dickmare potentially being grossed out by how much cum was getting on their body, the bed, or the floor, Summer Solstice was very different. She loved the filth and how it made her feel, becoming more turned on by just how stronger she was as a dickmare. Her much bigger head gave her a big head, her ego being stroked just as much as her dick was.

Her next orgasm, she brought a dildo to her thick ponut as she imagined getting fucked by another dickmare while still stroking off her fat cock with her magic. Wearing a cock ring to keep her dick big and hard, she also had a spell that she switched on and off to buzz at her p-spot. She kept it off as inch after inch of the dildo sunk into her fat ponut, then as it was hilted, turned it back on and blacked out to an unfathomable mess of pleasure and cum all over the bed and herself.

Another orgasm, jerking herself and her cum-slickened cock with her hooves, as she imagined putting her yoga instructor Tree Hugger in a mating press. The green earth pony’s messy locks would be made even messier from the loud thunderous fucking that would get the normally chill pony into a braying mess. Imagining busting a load into that dark green ponut, Summer loudly moaned as another fat load of creamy load landed into her dirty mane.

As she imagined Stellar Flare, her business professor, sucking her off and bobbing her normally bossy mouth up and down the dickmare’s dick, Summer moved the bottom half of her body to her face as she wrapped her mouth around her own dick. Sucking herself off was an incredible feat that was only truly made possible from the recent transformations to her own body, and Summer Solstice savored in taking that act to its deepest extreme as she was facefucking herself while imagining the fantasy of being blown so passionately. Stellar Flare would essentially be sucking off Summer’s own stellar flare, using her mouth for the best use the dickmare could imagine for her. She imagined that any of these mares should they let her, would easily become mindbroken from the dickmare and become impregnated in the process. She imagined Luster Dawn, Treehugger, and Stellar Flare all swollen with her foal and with the cutie mark on their bellies. Inevitably, that image turned into the mare that was impregnated by her: Izzy Moonbow. Summer managed to successfully hilt herself in her own mouth as she felt the tip of her cock in her own mouth, groaning as she swallowed her own thick seed that time.

As she slipped the entirety of her cock out of her mouth, Summer Solstice felt the searing disappointment of how she was pulled out of Izzy’s time and back into her own. If at least half of the mares were as hot, fuckable, and cute as Izzy Moonbow was, being sent back to Canterlot was a tragedy. Perhaps if she fucked more and more ponies in the timezone she was in now, with her newly altered body, it would affect the future and create more dickmares to fuck those cute mares. The time shenanigans were a longshot, and Summer wasn’t even entirely sure of how that would work or if that would work. The potential consequences of fucking with a future that was perfectly fine the way it was hardly mattered to the orange unicorn though. As far as she was concerned, she just wanted another reason to get off to the purple unicorn that was out of her reach.

Summer Solstice then turned to her dresser, opening it with her magic as she levitated a condom out of it. Bringing the condom to her massive futa bitchbreaker and tearing it open from the wrapper, Summer had those ones bought from a special shop that was a couple of towns over. She couldn’t even buy ones in Canterlot anymore, having them tear open every single time before she could even use them properly. Special ones that were enhanced with dark magic that didn’t instantly break, Summer stroked her giant cock with both her cum-soaked hooves as she grunted from the sound of the orgy still going on outside. She would’ve done anything for another plow of that purple slut’s ponut, and imagined herself mounting the mare generations into the future. The feminine moans outside of her room only brought her still built up balls to a quick orgasm, watching as the condom ballooned out with her thick seed and the rest that couldn’t fit spilled onto her balls. As soon as she finished cumming the condom into an inflated balloon, Summer Solstice slipped it off her quickly, sealing the end so that none of it escaped. Then, with a surge of hot arousal at what she was about to do, Summer brought the cumflated condom over the floor and opened it. Cum landing all over her own carpet, creating a stronger and hotter musk in the room that floated outside, Summer could only hear the plaps outside and the moans of lust skyrocket from what she had done.

The fiery orange unicorn then stood on all fours on the bed, still insatiable as she expected as she grabbed a fleshlight from underneath the blankets. A bright colorful pink and purple fleshlight that she sunk half her length into on the first go, Summer then pulled out a set of anal beads from her still open dresser as she brought it to her own lubed up ponut. Fucking from one end and being fucked from the other was an exquisite feeling that she could never get enough of, and hearing an excited audience outside was spurring her on as she imagined herself being on the end of a dickmare while fucking a mare. Perhaps it would be another dickmare while she was fucking her impregnated Izzy, with them mutually savoring the mindbreak of the once important mare. Summer pistoned her fat cock into the fleshlight, managing to slap her full balls against it as she hilted it while getting several of the anal beads inside her ponut with a deep shudder throughout her body. She was running on a high, an addiction of her body’s transformation that she wished she could say wasn’t her doing. But she made her choice knocking Izzy up, and being a slave to her body’s sexual desires only turned her on all the more. The aroused high she was running on, a deep and profound pleasure tingling from her legs to the tip of her horn, made Summer Solstice wish to give such a mind-bending feeling to every mare she possibly could. Whether they were a sub, dom, or something in between, Summer felt a carnal hunger devouring her mind in every way that she wanted to take out on a vulnerable mare. And Izzy Moonbow certainly was that, Summer could only imagine how hot and slutty her friends would be at the end of the dickmare’s cock. Groaning as she got all the anal beads inside her ponut, hilting her cock inside the fleshlight one more time, Summer came inside of it with a warm vibration pulsing inside her. She couldn’t get enough, there was more to be had.

Listening to explicit music on her phone, lyrics resonating with her in how addicted she was to her own lust, Summer stood over an empty mug as she used her magic to jerk herself off. Becoming addicted to the taste of her own enhanced cum was definitely not a level of debauchery that Summer expected to reach, but there the unicorn was shooting hot cum inside of the mug and waiting a few more moments to finish inside before using her magic to bring it to her lips, gulping down her own cum as the nasty hot muskiness caused another spurt of her seed to escape her body as she couldn’t get enough of herself and her new capabilities. Imagining Izzy and her friends on the receiving end, Summer Solstice knew that it would only get better with each mare she broke body, mind, and spirit…

Eventually, as the afternoon turned into evening, the final act began that spoke to Summer Solstice as a sign. On her phone that she was holding in front of her eyes with her magic, was a leaked tape of the big-maned pegasus Songbird Serenade and the normally demure singer Countess “Rara” Coloratura sucking the balls of an electric blue bitchbreaker. The mare had a white-furred body that sharply contrasted from the vividly blue dick she had, though only the bottom half of her body was visible in the leaked tape. Still, as Summer Solstice jerked off her cock with all four of her hooves and moaned deeply as a magical copy of her dick was fucking her own ass, the orange unicorn could take a good guess as to who the blue-dicked mare was. Regardless, it was absurdly hot to watch two singers she loved listening to giving in to their natural desires to superior dickmares. She could see both their winking pussies, both their colorful tails moved out of the way to reveal both said pussies and their ponuts. The both of them not caring in the slightest that they were being recorded by Celestia knows who, moaning against the dickmare’s fat balls before Songbird rested her forehooves on the she-stud’s leg and brought her lips to the tip of her electric blue tool. Summer moaned as she wasn’t even sure if Songbird was going to be able to open her mouth around such a fat cock, jerking herself off faster as she watched the white pegasus successfully take the tip in her mouth. Even Coloratura seemed turned on by the feat of her fellow singer slut, beginning to lose more and more of her usual modesty as she opened her mouth wide and slathered the electric blue balls before her.

Not even sucking quietly anymore, Coloratura moaned loudly as she twerked her fat aquamarine gray ass for the camera as she drooled all over the balls in front of her. Hearing that loud clap of the singer’s cheeks, while watching Songbird’s mouth go down over the dickmare’s cock slowly, Summer started having her own fat ass plapped by her dick copy in her ponut. Her eyes rolled to the back of her head for a few moments, getting close to her last orgasm of the night before she refocused her eyes just in time to see Songbird jerking off the she-stud’s dick with her wings while Coloratura rubbed the dickmare’s balls while kissing up and down the base of her dick. The mostly still dickmare gave a sharp thrust in the air as she released a fat dollop of seed all over the both of them before another followed. Rope after rope of the she-stud’s seed landed on both Songbird and Coloratura as they closed their eyes and moved closer to get as much of it as possible. Then, after the dickmare was completely spent, the two singers began to lick the cum off each other. Summer brought the tip of her own cock to her mouth again, feeling her fiery hot peak cumming any second now when Songbird and Coloratura brought their lips together and began swapping the loads of cum between their mouths. Summer felt her balls empty inside her mouth as her mind blanked out, gulping down her own impressive load on cum and feeling it hit her belly with that familiar dirty warmth settling in. With her magical copy cock hilted in her ass, Summer shuddered with delight at just how much she came in just one day.

As she slipped her cock out of her mouth, and the magical copy out of her ass, she looked to the filled pink and purple fleshlight sitting on the corner of the bed. Her exhausted and vaguely horny brain drifted back to Izzy Moonbow. As fun as the fleshlight and the porn was, she knew that the real deal blew all of that out of the water. That thick purple ponut and those needy cries for more cock, Izzy wasn’t somepony that Summer Solstice had forgotten. And the stronger dickmare wasn’t going to miss out on the opportunity to meet her friends.

Summer Solstice needed to return to the future, and would practice more of her time magic so that it wasn’t a short-lived accident this time.
