Usually, a mare will turn you down on an offer to go swimming. Occasionally, though, you get really lucky.

Quick Wit has never had much luck with mares. Despite the accuracy of his name, his lack of muscle as an earth pony has made him relatively undesirable. On vacation at the beach south of Manehatten, though, he decides to try his luck on a mare that he's sure he has no chance with.

Today, his luck serves him well.

Originally written for Fun in the Sun, but I think everyone can see how that turned out.

Foolin' in the Foam

Author's Note

Would have had this out in time, but I couldn't figure out a decent ending. After a short(read: month-and-a-half) bout of feeling sorry for myself, I've finally started getting my drive to do things back.

'Bout damn time, eh, chaps?

Foolin' in the Foam

Quick Wit walked down the beach slowly, looking around. It was the last day of his week off, and he refused to leave the beach today without a mare. It had been far too long since he last got laid, and there was no way he was going back to his daily grind without having some serious sex first.

Unfortunately, Quick Wit was an earth pony who worked a desk job. This meant that unlike most earth ponies, who would have no problem getting mares thanks to their natural affinity for hard work, which in turn gave most earth ponies muscled, or at least, well-toned, bodies. Quick Wit, while certainly not fat, did not do nearly as much hard work as most earth ponies, so instead of being toned, he was just kind of scrawny.

On the last day of his vacation, though, that would not stop him. He would find a pretty mare, he would convince her to come back to the hotel with him, and then he would give her the best fuck of her life. He had been walking for almost twenty minutes, now, and he knew he would have to turn back soon, just so he would actually be able to get back to the hotel in a timely manner. He kept looking around, trying to find a mare that didn't seem to be with a stallion. There had been a couple already, but they had all turned him down. It was slightly disheartening, how they had refused without even the slightest hesitation, but he wasn't going to give up yet. There had to be at least one mare out here that would be willing. It was, like, probability or something. Right?

He saw an ice cream shop a little ways away, and decided that would be a good place to turn around. He was quite a ways away from the hotel, now, and he didn't want to be arriving with his date after dark. When he finally got to the shop, the line was surprisingly short, with only a handful of ponies in front of him. He took the time to look around anyway, not really expecting any single mares to be around. To his surprise, though, he spotted one almost immediately.

She was laying on a sun chair, her legs crossed, reading a book. She was a pegasus, evidenced by the wings on her back, and she was a gorgeous shade of royal purple. The book covered most of her head, including her face, but her mane and tail were still visible, contrasting her coat color with a dark indigo, streaked with a single line of pink and a purple a little darker than her fur. Her bikini only helped her, the stripes making her hips and breasts look even larger than they already were. Sitting next to her in another sun chair, a white unicorn was sunning herself. She was beautiful as well, but Quick Wit knew he had no chance with her. Her mane and tail were curled to perfection, her hooves were immaculate, and her fur was utterly pristine. She obviously had no interest in anyone other than the best. She had probably already sent away a number of stallions who had propositioned her. It was obvious, at least to Quick Wit, that the pegasus with the book was single. Nopony goes to the beach with their special somepony and then reads a book.

He turned his attention back to the line in front of him, and noticed it had moved forward a step. The pony currently at the counter was taking his time. Looking back at the mare, Quick Wit also noticed a few more towels and a couple of sun chairs that were still folded up. He knew those would only be there if she had come with friends, further evidence she was single. Any mare in a relationship would be with her friends as much as possible, since most of her time would normally be taken up with maintaining and progressing said relationship. He was certain, now. She was single, and that meant he at least had a chance. A plan quickly formulated in his mind as the line moved again. There were only two ponies in front of him now.

As of yet, he knew nothing about the mare, but the chances of her not liking chocolate ice cream were almost nonexistent. As another pony walked away with their cone, Quick Wit started thinking about his introduction. He needed something clever, but he didn't want to risk her friends returning, or worse, all of them leaving, before he could come up with something completely unique. The pony in front of him rubbed her forehead and flicked some sweat away. It was all Quick Wit needed to come up with a decent icebreaker. With his plan laid out, he stepped up to the counter, ordered a double scoop of chocolate, and then a double scoop of mint chocolate chip as well. Now properly armed, he started making his way to the gorgeous pegasus with the book. There were a couple of times when he almost tripped and dropped the ice cream, but he managed to keep it all under control long enough to get near his destination. As he did, though, the white unicorn seemed to take notice of him. Her head tilted almost imperceptibly, and one of her eyebrows went up. He approached her friend, and she smiled before her head went back to its previous position as she relaxed. Quick Wit, apparently having not been noticed by his target yet, took a breath to calm down, then opened his mouth.

"Hi there. I thought you looked pretty hot over here, so I bought you some ice cream." He put on a winning smile and held the cone of chocolate ice cream out to the pegasus. She lowered her book in surprise, revealing that she was not, in fact, a pegasus at all. She had the wings of a pegasus, but the horn on her forehead, previously concealed by the book she had been reading, was more than enough proof for Quick Wit to be sure he had made a terrible mistake. The gorgeous pegasus was actually a gorgeous alicorn, and therefore, a princess. He was doomed.

"Um, thanks." She reached out and took the ice cream, snapping Quick Wit out of his fear-induced trance. "Wow. I haven't had a stallion hit on me since before my ascension. That was a pretty good line, though, I'll give you that."

Quick Wit’s frozen smile turned sheepish as he realized that he would have to step his game up an extra couple of notches. Most mares would either act flustered or brush him off if they figured out what was happening. He had not expected her reaction, though.

"Heh. Thanks. I tried to make it a bit more subtle, but I guess I'm not as clever as I thought, huh?"

"Oh, you did fine. I'm just better at picking up those kinds of things. I spend a lot of time reading and studying. I knew what most of the pickup lines stallions use are before I turned fifteen. I haven’t heard that one before, though.”

Quick Wit recovered after she said that. If everything she’d said up to that point was true, then maybe he did still have a chance. He licked the edges of his ice cream to keep the melted drops from falling off, mimicking the princess’ actions, then spoke again.

“So, what’s your name? I’ll bet it’s almost as pretty as you are.” It was a fairly cheesy line, and he knew it, but she smiled around her ice cream.

“Twilight Sparkle. And yours?”

“Quick Wit.”

She giggled, and Quick Wit felt his confidence return. All he had to do was not say or do anything completely stupid.

“That’s an interesting name, although it does explain your pickup lines. Is it alright if I call you ‘Wit’?”

He gave another big grin.

“Only if it’s okay for me to call you ‘Twilight’.”

She took a small bite out her ice cream as she giggled.

“I prefer ponies to call me that, actually. Unfortunately, since my coronation as a princess, most folks have stopped using my actual name. It’s a bit off-putting, actually. It’s not like I’m a totally different pony, now. I still do all the things I used to. Well, except the things that require other ponies who aren’t so scared of being put in the dungeon for making a mistake that they can’t do their part properly at all.”

Quick Wit didn’t need to think too hard about her meaning as he swallowed another bite of ice cream. Twilight’s wings had fluttered and she had rubbed her hooves together almost incessantly for the whole explanation. She wanted release at least as much as he did. The tricky part would be convincing her to let him be the one to get her off. It always was. She would give him that opening when she was ready, though. Until then, he just had to keep her attention on him. He looked around as they both ate their ice cream, again noticing the towels.

“I’m guessing you’re here with your friends, right?”

She nodded as she struggled to reclaim a small chunk of ice cream that was falling off her cone.

“Yeah. And that reminds me, I didn’t introduce you to Rarity! I’m sorry!”

The white unicorn next to her waved a hand dismissively.

“Quite alright, darling. I didn't want to interrupt his attempt, is all. The poor dear looked like he was about to faint when he saw your horn."

Quick Wit stared for a moment at Rarity, who was smiling in amusement, as Twilight took another lick of ice cream and shook her head.

"Don't mind her, Wit. She's a hopeless romantic." She finished her cone with a few more bites, then stood up and stretched, arching her back and showing off her bust. Quick Wit ate what little remained of his cone as well, then got to his own hooves. "So, what was your grand plan after getting my attention?"

"I was planning on asking you to swim with me, but I'm pretty sure you're supposed to wait half an hour after eating." Quick Wit smiled sheepishly as Twilight walked past him, fluttering her wings attractively. He felt a stirring in his lower body as she shook her head, letting her hair wave at him as he followed.

"Actually, there's no scientific evidence for that. Besides, as long as we move slowly at first, it won't be a problem, anyway. Although, if you want to stay here on the beach, I don't mind going out by myself." She sashayed her hips at the end, and looked over her shoulder with half-lidded eyes and a teasing smile.

"I don't think I would make you go out there alone even if I knew for a fact that I would cramp up and sink. Letting a beautiful mare like you go swimming alone should be against the law." They both waded into the surf, shivering pleasantly as the warm salt water soaked their fur. Twilight giggled.

"Well then, mister law-man, come and arrest me." He saw her horn glow for a moment, then she bent over, giving a heavenly view of her plot for a split second before diving under the water. He could see her begin to swim away below the surface, using her wings for extra propulsion. He smiled to himself, unable to believe how well this had turned out, then took a deep breath and followed. The salt water stung his eyes, but her purple coat was easy to make out as she moved away from him. He followed with fast strokes, trying to keep up with her slow, powerful wing flaps, which propelled her further than just her arms would have. Before long, he found himself needing air. Twilight didn't seem to be making any effort to move towards the surface, but he would have to go up soon. He saw her swim under a large rock, and then stop, turning so that her wings stuck out from the small alcove it formed. As he got closer, he saw a ring around her head, but he couldn't tell what it was. His lungs burned, but she didn't seem to care how long she had been underwater.

As he got close, he saw her horn light up, and the water suddenly retreated from his face. He gasped as he found himself able to breathe again, and pushed his mane back as it clung to his face. He kept kicking his legs, moving under the rock with her, then righted himself as her features became clear through the haze of salt water between them. He could now see that the ring around her head was a bubble of air as well, no doubt a spell she had cast when her horn had lit up before. When he got close enough, she reached out and grabbed his outstretched arm, pulling him close enough that the two bubbles connected, letting them hear each other.

"You cheated," Quick Wit said, feeling his loins throb as he looked at Twilight, her mane wet and sticking to her face and neck as she giggled.

"I can't hold my breath for very long, and I didn't want anypony to see me surface and get curious about what I was doing." The parts of her mane still in the water floated lazily, haloing her head with indigo while her feathers quivered in the undercurrents.

"Well," Wit said, "how did you know I wouldn't go up for air?"

Twilight smiled at him lustily, and her horn lit, pushing the water down and away so they could move normally. Her mane fell with the water level, splaying over her shoulders, and down her back and chest.

"I know a lot of earth ponies. All of them can hold their breath for a long time, and that's without knowing they're about to get laid." As Wit's brain finished processing that information, Twilight suddenly dove forward, pressing her lips against his as the water fell below their waists. With a new assurance of what was to come, the churning in Wit's lower body quickly grew to a full erection. He began returning the fervent kiss in full, using his tongue to grapple with Twilight's between their mouths. She pressed her body to his, smooshing her breasts against his chest and pinning his cock against his leg, then started gyrating her whole body. She rubbed up his body, pulled away just enough to be able to move, then moved back down before pressing against him again and repeating the process. As she did this, the water level dropped down to their tops of their hooves.

Every step made a small splash as the sun filtered through the ocean above them, throwing an ever-changing kaleidoscope of light onto their bodies. When Twilight was satisfied at the amount of space she had made, and how much Wit's cock throbbed against her thigh through his swim shorts, she began moving down. She continued rubbing her body against his, but every downward motion was a little bit longer, and every upward motion a little bit shorter. Finally, she was on her knees, holding her thighs vertically as she rubbed her tits against Wit's groin. She looked back up at him with wide, innocent eyes, and a decidedly not innocent smile.

"It feels like you have something in your shorts, Wit. Did you bring a present for me besides the ice cream?" She pulled back and started rubbing her hand against the bulge running down the length of his shorts. He grunted as the stimulation began knocking down his inhibitions. He needed this, and apparently, so did she.

"It's more a reusable present delivery system. You'll have to take it out to use it, though." He gave her a toothy smile, and she giggled back at him before sliding both hands up his legs and hooking her fingers over the waistband. She slowly slid his shorts down, watching his member strain against the fabric and bend slightly under its own strength. When it was finally free of the offending swimwear, it sprang up, forcing Twilight to dodge to one side as it bobbed up and down next to her muzzle. Licking her lips, she looked up at Quick Wit's face again.

"It's okay if I take more than one present, right? It looks like nopony else has taken you up on your offer lately, so I can have theirs, right?" Still keeping her eyes locked on Wit's, Twilight stuck her tongue out and ran the tip down the side of his cock, towards the base. He shivered with pleasure and gave her a lust-filled smile.

"Oh, that's no problem. It refills itself anyway, so you can have everything I've got today."

Twilight smiled even wider and kissed his dick just past where his sheath ended and the warm, smooth, throbbing flesh began. She then dragged her lips back up his length, pushing it upward as she went, and grabbed him behind his medial ring. She leaned back, her eyes glittering with lust as the light filtered and reflected off of them, and paused for a moment, letting Wit burn the image of her holding his cock into his memory. His dick throbbed again, and Twilight took that as her cue to continue.

"Time to find out what you got me." She cut right to the chase, opening her mouth wide and taking the first four or five inches into her muzzle immediately. Wit gasped from the sudden change in sensation on his dick, and repositioned his hooves so he didn't fall over. Twilight didn't move her head back, holding herself still as she used her tongue to lather Wit's dick with saliva. It had a very different taste from the other stallions she had done this for, since none of them had been forced to swim through salt water to get to this point. It made for a unique experience as she finally, slowly, began to pull her head back, sucking hard and holding his ring tight to make as much stimulation as possible. She felt his pulse quicken in her mouth, and swirled her tongue against the flat of his head when she reached the end of his shaft.

"Feel good?" she asked with her lips still drawn tight around his head. He nodded breathlessly.

"Oh yeah, Twilight. That feels really good."

She sank her head down again, slurping on his cock as she went, and tilted her head when she moved back, twisting her mouth on his length. Wit groaned and put a hand on her head, partly to guide her and partly to help him keep his balance better. Twilight took the contact as encouragement, and started moving a little faster, building a rhythm of slurping. She sank slowly down his cock again, and paused at her previous limit. She made a low hum, sending the vibrations through him, then began moving down again. She was almost painfully slow in doing so, but Wit marveled at her just the same as her lips reached his ring before finally stopping.

He could feel the tip of his penis at the edge of her throat, hanging on the very back of her tongue, which still moved and swirled on his length incessantly. Another hum through his flesh made him want to buck his hips and feed her the rest of his meat, but he held himself back. Without warning, however, he found his wish granted anyway as Twilight suddenly pushed forward, angling her body to put her esophagus more in line with her mouth so she could swallow his rock-hard erection, which refused to bend and follow the turn of her throat. He felt her trying to swallow him, and pushed forward gently to help her. Suddenly, Wit felt his cock push past her tongue and Twilight's head pitched another half-inch down his length.

He could feel the slight tingle of air rushing past his head as Twilight breathed through her nose, her mouth still busy servicing the base near his sheath. She tilted her head left and right, sticking out her tongue as she tried to cover every last bit of bare flesh with her spit. Twilight repositioned herself, moving her legs back and leaning her arms on Wit's legs so she could start bobbing her upper body back and forth, suppressing her gag reflex and swallowing the delicious stallion meat blocking her airway as she drooled a little. It didn't take long for her to feel the muscles in Wit's legs clench from her enthusiastic sucking and slurping.

"Twilight," Quick Wit gasped as her tongue dragged against his medial ring again, "I'm getting close. Get ready!" He grunted, trying to hold back his climax so Twilight would be able to get his cock out of her throat first. She didn't slow down, though, even as she started moving backward in preparation of removing his dick. When his tip reached her tongue, however, she made a somewhat alarming discovery. He was already partially flared, and she couldn’t get him the rest of the way out.

For an instant, she considered stopping, but if he was already that close, it was possible that doing so would make him completely flaccid, especially since he might take it as being his fault. Neither of them wanted the encounter to end like that, so instead, she prepared herself for the deluge that would erupt directly into her throat, mentally getting ready for his ejaculation. When he finally came, he came hard. Twilight tried to swallow as much as possible, gulping down wads of semen as fast as she could. It wasn’t enough, though, and the cum started flooding her throat, seeping between the flesh of her mouth and the flesh of the cock it had spewed from onto her tongue, then past her lips and down her chin. More of it overflowed into her sinuses, and she coughed as her body tried to breathe again, causing the semen in her nose to spill out of her snout. She kept swallowing, though, stemming the tide just enough to be able to occasionally inhale and not pass out.

When the torrent finally ceased and Wit's tip shrank back to a managable size, Twilight slowly pulled off, coughing lightly once he was completely out of her mouth. She held him still, though, and once she had her breathing back under control, she licked his cock clean. Quick Wit, for his part, had been worried she would be mad at him when he realized what was happening. Having her clean his semen off with her tongue, however, had allayed that worry entirely. There was still quite a bit of cum on her muzzle and tits, but a simple self-cleaning spell sent it into the wall of water next to them. Twilight then pulled Quick Wit down to the ground, and pushed him onto his back, grinning in a lasciviously predatorial manner.

"You didn't think you were done, did you?"

Wit blanched.

"Well, I figured you would probably want me to get you off too, but-" He was cut off as Twilight's horn lit. He could feel her magic on his balls, and she was grinding her pussy against his flaccid dick, reawakening it for another round.

"Oh, no. I haven't gotten to try this position yet, and since you were so eager to play with me, you're going to lay there, and let me take some notes on how this feels. Trust me, Wit, you chose the best possible mare to hit on today. I'm going to make you cum at least three more times before we're done." She pulled her bikini bottom off to the side, revealing her glistening pussy, as Quick Wit felt her magic leave his balls. He had no idea what she had done. Twilight then slid her folds along Quick Wit's member, making his dick so hard that it hurt. She moaned quietly, enjoying the sensation of her outer lips parting along his shaft, and leaned forward, putting her hands on his chest to balance herself. She grinned at him, and lifted her lower body. Holding it there, she rubbed her hands over his chest.

"Well? You want to feel me from the inside, don't you? Come on, put your shaft in me." Doing as he was told, Quick Wit grabbed his dick and lifted the tip up against Twilight's folds. She let her weight press against his head, before he grabbed her hips and started gently pulling. She parted fairly easily, but her overall lack of experience still left her wonderfully tight, squeezing the entire length of Wit's cock as he slipped into her inch by inch. When she finally had his entire cock in her snatch, with the tip just barely pressing against her cervix, she moaned again, and ground her hips against his. His dick swirled inside her as she moved, pressing against every part of her walls. He groned as well, bucking slightly as his body tried to do want it was made to do. Finally, Twilight stopped teasing him and gave in to her instincts. She slowly raised her hips, relishing every inch of his cock as it slid against her inner flesh. When Wit's head was the only part of him still in her, she fell back down, impaling herself not-quite-painfully on his shaft and slapping their groins together. She let out a high-pitched moan, then did it again. She repeated the action several times, ramming herself onto Wit's cock hard and feeling his tip spread her inner walls roughly.

Before long, though, she wanted more. She began increasing her pace, dropping her pussy down his shaft over and over and he dug his hands into her hips in pleasure. The splashing that accompanied every motion of her legs only accentuated their lust for one another, and soon, Twilight was leaning forward over Wit's body, frantically bucking her hips up and down his dick while her tits bounced above his face. They were hypnotic, even with her bikini still on, and Quick Wit wanted to grope and squeeze and suck them, but his hands were occupied with helping Twilight force her snatch down his length, pressing hard into her cutie marks. Finally, Quick Wit felt his groin tense, preparing another load for the princess's enjoyment. He tried to push her off, but she slammed her hips down to his and held them there, grinding herself against him again to finish him off. Just as he reached his peak, Twilight dove down and mashed her lips against his, invading his mouth with her tongue as he blew his load inside her. She could feel him pulsing over and over, and each throb through his cock made the warmth it injected into her spread a little further. Her own climax suddenly crashed through her when she felt Wit suck on her tongue and squeeze her flanks simultaneously. She moaned into his mouth, enjoying the sensation of her pussy milking every last drop of semen out of Wit's dick.

Once they were both finished, Twilight pulled her mouth away from Quick Wit. She could feel him going soft inside her. He was probably almost empty by now. Her research on sex, though she had done it in her school years and it was therefore out of date, had led her to the conclusion that most stallions could ejaculate three times before they were utterly spent. That meant he had one more good cumshot for her, and after that, she would need to use the spell she had made in tandem with her research to continue. First, though, she wanted to find out what it felt like to have him return to full erection in her pussy, and she had just the thing for that. Two of them, actually.

She sat up, Quick Wit's dick still ensconced in her snatch, and gently grabbed his hands. He had subconsciously had his fingers pressed into her flanks after his orgasm, but he let go when she grabbed him. She guided his hands up, sliding them along her body, and brought them to a rest on her tits. She pressed his hands down on them, and he squeezed.

"Oh, yeah, Wit. I know you like my tits. Go on, play with them."

He wasted no time in taking that offer, squeezing them as hard as he dared, and making her nipples show through her bikini. He decided he had waited long enough, and pulled the fabric to either side, using the bikini itself to hold her breasts together. He pulled her down closer, and leaned his head up to suck on a nipple. Twilight tilted her head back and moaned, lost in the rapture of his attention to her breasts and the feeling of his cock growing again in her pussy. He licked and suckled each nipple in turn, switching between them while the water lapped at his sides. He pushed Twilight's tits together, and angled them toward each other before grabbing both nipples with his lips and sucking hard. Twilight gasped and whined.

"Oh sweet Celestia! That feels so good! Don't stop!"

Quick Wit grinned.

"I have a better idea." He suddenly rolled, putting Twilight on her back as her wings snapped out in unexpected arousal. She hadn't realized that having a stallion suddenly take control would turn her on so much. He pulled his cock -fully erect once again- from her pussy and moved up, straddling her belly. She could feel some of their mixed fluids seeping out of her hole, she could feel the salt water gently massaging her wings, and as Wit lowered himself, she could feel his dick, slick with cum, lay against her belly before pushing upward. Quick Wit held onto her breasts, squeezing and massaging them as he moved his hips forward, pressing the tip of his dick against the bottom of her chest. He repositioned his legs, moving into a better spot, and pushed his cock between her mounds. The previous lubrication let his length move freely against her fur, and he continued pushing forward until his head poked her in the chin. He stayed there for a moment, relishing the texture of her tits around his shaft, until he felt her rubbing her chin against him. He looked down to see her giving him a grin so sultry it could have made butter hard.

"You just going to sit there, or are you going to fuck my tits and cum on my face?"

Wit's dick throbbed hard with desire when she said that, and he immediately pulled back to start thrusting against her chest. Her fur was already soft and smooth, and the cum that covered his length only served to reduce the friction even further as he slid back and forth. He squeezed the delectable mounds of flesh together tighter, giving himself more stimulation, while Twilight stretched her arms over her head, giving him full control of the situation. After a few seconds, though, she got bored of simply feeling him between her breasts. She looked down at the molesting appendage as it grew and shrank in her vision over and over. She wanted him to cum just like this. She wanted to see his jizz explode from his tip and shoot all over her face and into her mane. She opened her mouth and stuck out her tongue as Wit moved forward, and sucked for just a moment on his tip when it came in range of her lips. Wit gasped from the sudden stimulation, but kept going, allowing Twilight to lick or slurp at his tip every time he moved forward.

He stopped after several seconds and held his dick where she could reach it. Understanding what he wanted immediately, Twilight worked as much of his shaft as she could reach for a few seconds before he pulled away again and resumed fucking her tits. He continued doing this, pausing every so often so she could blow him some more, and enjoying the feeling of her silky fur and warm flesh. Twilight, for her part, was thoroughly enjoying his cock as it slipped in and out of her breasts and mouth. She enjoyed simply laying there, exerting a minimal amount of effort as Quick Wit used her body to get off. Finally, she felt his balls throb below her tits, signaling his imminent climax.

"Twilight, I'm gonna cum again."

"You don't have to tell me. I can feel your balls clenching. Let it out, Wit. Shoot that load for your princess."

He didn't have to be told twice, and kept thrusting between her mounds as he fired heavy ropes of semen onto her face and mane, and into her nose and open mouth. After several seconds of being painted white, Twilight giggled. She had gotten exactly what she wanted out of that burst. She could feel her fur and hair matting together, and she knew she must have looked pretty damn sexy covered in jizz. She watched with one eye -the other had two strands of cum going over it- as Quick Wit pulled his cock from between her tits and under her bikini so he could fall over into the water next to her, panting.

"That... was... amazing," he said between breaths. "I don't think I've ever gotten off so many times in one day before, and I doubt I ever will again."

Twilight grinned as she licked some cum from her muzzle.

"How would you like to cum even more? There's a spell I made, a long time ago, that increases sperm production in stallions. I've never tested it before, but I'm sure it'll work. Care to be my first subject?"

Quick Wit thought about that for several moments. On the one hand, he was tired. He hadn't done very much, true, but ejaculating three times had taken a toll on his endurance. Not only that, but his dick was beginning to get sore. He didn't want any bruises or chafing down there. On the other hand, though, he would probably never get to fuck a princess again. He didn't want to reduce what little chance there was of her agreeing to another session by refusing a request from her. Plus, he would get to test out a spell for her! Everypony knew that Princess Twilight Sparkle's spells were powerful. A sex spell she made herself would probably do wonders for him, at least temporarily.

"Okay, sure." He sat up and opened his legs to give her a clear view.

Twilight, for her part, was thrilled at finally being able to try out her spell. She had tweaked it here and there over the years, fixing problems she spotted every time she looked at the formula longingly, and now she was certain it was ready for use. She channelled her magic, and her horn lit with energy as she focused on Wit's balls, making them better at what they already did. When she was sure the spell had worked, she used another spell to relieve his exhaustion. She wanted him to enjoy this last ejaculation, and he couldn't do that if he was sore everywhere. Her magic faded, and Quick Wit stood back up, his cock visibly throbbing at full mast. Twilight swallowed as her mouth filled with drool.

“I feel great!” Wit stroked his member a couple of times, then looked at Twilight and grinned. “You ready for me to really fuck you?”

Twilight licked her lips and nodded. This was what she had been waiting for. Quick Wit walked over to her, and held out his hand to help her up. She took it, and once she was on her feet, he spun her around. Her wings were soaked and useless, hanging limply at her sides as he bent her over, making her face toward the rock they were under so she could lean against it. He rubbed her ass a few times with his hands, then pulled her bikini bottom down to reveal her cheeks fully. He pulled her ass cheeks apart, making her moan, then laid his dick between them. He rubbed his length between her cheeks, hotdogging himself pleasantly while Twilight let out small moans and whines of pleasure. Finally, he stopped his teasing and took a step back, lining up his rod with her anus. He pressed his tip to her backdoor, and she moaned pleadingly.

She wanted it, and he was going to give it to her.

He gently pushed forward, adding more force to get past the tight resistance her ass presented. After a few seconds, he suddenly slipped in, making both ponies gasp in pleasure. He barely fit inside her, and the tightness was unreal. He pushed more of his length inside, slowly but surely, until he was buried to the hilt. He stayed like that for several seconds, letting Twilight get used to having him there and enjoying the movement of her muscles as she shifted her weight. Once he was sure she was ready, he slowly pulled back out to his tip, then just as slowly drove back in. He began picking up his pace as he went, until his hips slapped against hers with every thrust.

“F-faster.”

Quick Wit almost didn’t hear his partner speak over the sound of their sex, and stopped for a moment.

“What was that?”

Twilight tossed her mane back, showing a desperate face with her tongue hanging out.

“Faster! Fuck me faster! It feels so good!”

Grinning, Wit did as he was told, fucking her at a reasonable pace.

“Faster! I need your cock slamming into me!”

He obeyed, grunting with exertion as the sounds of their hips slapping together began to slur in his ears.

“Yes! That’s it! Fuck me, Wit! Hard and fast, just like this! Oh, yes. Oh, yes. Oh, yes! You’re gonna make me cum. Make me cum! Make my juices spurt out of my pussy and then cum in my ass! Fill me with your seed! Don’t stop fucking me!”

Wit could feel his orgasm building, even as Twilight’s muscles clenched around his member. He pushed her hips down just a little, changing the angle of his cock just enough to make Twilight scream in pleasure as she finally came. Her muscles rippled around Wit’s dick, sending him over the edge just as she came down from her own high. He felt his balls swell and clench, and it suddenly felt like his dick was going to explode. Instead, a massive stream of semen shot from the tip. This wasn’t his normal load size, though. The first pulse of his shaft sent a torrent not unlike a garden hose into Twilight’s ass, and took almost three full seconds to finish. He could feel the flood of cum trying to escape between his cock and her anus, but the tight fit denied any passage. The second burst was just as inordinately huge, and Quick Wit suddenly realized it wasn’t going to stop in a normal time frame, either.

Twilight, being the recipient of such an enormous spray, instantly recognized that something had not been accounted for in her spell. It didn’t really matter what it was, though, as she felt the third eruption of cum move further up her ass than she had ever intended to be able to feel. She thought, for a moment, about telling him to pull out, to blow his load safely over her body. As she did some quick estimations in her head, though, she came to the conclusion that his ejaculation would most likely not just increase in size, but also duration. As a fourth jet of semen pushed almost halfway through her intestines, giving her a distinct sensation of vertigo, she also determined that the duration would increase proportionally to the volume. If that was the case, she was fairly certain that allowing that much cum into the ocean in one place at one time would poison the water for quite some distance. Her mind reeled with the possible consequences as another spurt of semen filled her intestines almost completely. She also knew she wouldn’t be able to take it all herself, so she quickly used her magic to grab some sand and superheat it. Another burst of cum, and she felt her stomach begin to fill. Her bloated intestines were already pushing her belly out, and she worked quickly to turn the molten sand into a hollow cylinder, one foot in diameter and half a foot long. More cum was injected into her stomach as she used the water around her to cool the cylinder into a solid. She drove it into the sand, then drove her magic straight down like a drill, shoving the sand below to the sides to make a hole almost fifty yards deep. She finished just in time as a particularly large burst of cum sped its way through her digestive tract and into her stomach, making her nauseous as it sloshed around.

She looked like she was halfway through a pregnancy now, and Quick Wit was showing no signs of slowing as he gasped and groaned in pleasure, lost to his own orgasm. His cock kept flooding her with semen, and her body finally gave up trying to hold it in. She felt it overflow into her esophagus, and then her gag reflex kicked in. She vomited cum into the hole she had made, and felt her belly shrink a little. For all the worry she had about how much semen Wit was producing, though, the slow, almost methodical pulses of his cock, coupled with the feeling of hot cum traveling through her, still felt terrifically sensual. When she was still a unicorn, she had fantasized on multiple occasions about being used like a fucktoy, not having to worry about whether she was pretty or skilled, just letting some stallion rut her silly and take away all the responsibility she had to shoulder. After her ascension, the fantasies had only increased in frequency. The extra stress that came with being a princess had not been kind to her, and she had been desperately craving a lust-filled romp with no expectation for her to be a perfect princess.

As more cum spewed from her maw into the hole, she realized she had that. The stallion currently shooting his cum through her body had not required anything from her, except that she be willing to let him get off using her body over and over again. More cum shot out of her mouth, and she felt her arousal reaching new heights as she felt Quick Wit start pounding her ass again. She puked more cum, then took a glance back to see a euphoric grin splitting his muzzle. She turned back to the hole as another wave of cum tripped her gag reflex, then lifted her leg up. Quick Wit got the hint and raised her leg over his shoulder, letting him see her tits bouncing while he fucked her and she puked up more semen. The idea that she was, for all intents and purposes, at his mercy turned her on more. She felt her nethers clench as her climax built. More cum shot from her mouth into the hole.

Now, though, it didn’t seem to be as much as before. The next pulse of jizz seemed to take longer, and was definitely smaller. Twilight pressed on her stomach, and belched out more cum as the next load blew through her. Finally, she felt that enough had been disposed of to be safe. She suddenly pulled away from Wit’s cock, and dropped to her knees, letting the next spray hit her in the cheek. It splattered against her head, coating her arm and shoulder. She grinned, opening her mouth and facing fully towards him while she cupped her breasts. The next pulse hit her squarely on the tongue, and as his dick flexed with the tensing muscles behind it, the stream moved up, shooting her in the snout. She left her mouth open, snorting to remove the cum in her nose as what was in her mouth poured from her muzzle down her front. The next burst went under her muzzle, sliding along her chin before impacting her neck and splattering uncontrollably across her front.

Wit suddenly pushed her back, putting his spurting cock between her tits. She grinned as a stream shot up one side of her face, propelling her mane on that side to the top of her head. She grabbed her breasts properly, and began using them to stroke Wit's length as it spewed cum up to her jaw.

"Yeah, you like my royal rack, huh? Show me how much you like my tits, Wit. Empty your sack on my chest."

He fired another stream at her chin, then stood up, stroking himself and covering Twilight's upper body with massive spurts of cum. She moaned and writhed, splashing in the water and squeezing her tits pleasurably. Finally, the torrent died down, dripping and splattering on her belly as Quick Wit panted. All of the stamina that Twilight's spell had given him was now gone. His member hung limp, a steady trickle of cum dripping onto Twilight's thighs. He took a couple of shaky steps to the side, then fell to his knees in an area that wasn't fifty percent semen. He turned and fell the rest of the way onto his back, breathless. Twilight licked her lips free of cum, swallowed, then rolled over and crawled to the wall of water, holding her breath as she allowed the current to clean her fur. She then crawled back, over to where Quick Wit lay, and plopped down on top of him.

"So... feeling satisfied?"

Wit grinned.

"Princess, that was the best sex I've ever had." He leaned his head forward and kissed her lightly.

"Careful, or I might make you come home with me."

"I don't think I'd mind that very much."
