Big Macintosh honestly did not know what to think. When he found Apple Bloom during the day, she–he was playing with his old friends, just like when they were fillies, like they didn’t have a care in the world. It went against everything Mac knew about the estrus season. That Sweetie Belle and Scootaloo should have been crawling all over him with their estrus perverted ways. Mac watched quietly from a distance, as they left the clubhouse to go into town for a treat and a game. Not a single tail flag between the two of them.

Soon enough Apple Bloom hit the playground, and every filly started gravitating towards him, but then Mac was impressed when Apple Bloom just calmly shook his head, waved off any attention and stood his ground. He didn’t let the fillies bully him around at all, and certainly didn’t seem tempted by any overeager but uncomprehending fillies sticking their posterior in his direction. He wasn’t even getting mad or frustrated, just smoothly dealing with them, and treating them with what looked like honest respect, if a bit pitying.

Is it possible Discord’s curse didn’t make Apple Bloom a real colt? He had all the actions and signs of one, and it sure convinced the fillies, boy did it, but maybe Apple Bloom just wasn’t feeling it? Maybe it just got rid of her estrus, and didn’t do anything besides that? Big Mac shook his head at his own foolishness, jumping to such harebrained conclusions. The obvious answer was that Apple Bloom is just a good pony at heart, and the fil–the colt was being a perfect lord, because it was Apple Bloom in there. Even when he got a stiffy, Apple Bloom didn’t go beat one out, like any colt with less restraint and tact would have done right away. Even Big Macintosh had to struggle not to let his hooves stray south this time of year. Maybe Apple Bloom was just a good pony, and Big Macintosh should trust her—his judgement and grace.

That’s why when Apple Bloom said, “So, my friends and I are havin’ a meeting after my chores. We’re gonna be at the clubhouse, but it won’t take long and ah’ll be back before dinner. I even got a alarm clock there to set and make sure of it. So can I please please please please please–”

“Yup,” said Big Macintosh, munching serenely on his sprout sandwich. Apple Bloom had chosen a hearty cream and mushroom lunch with, a satisfying helping of dark green spinach and a cup of cinnamon applesauce. It looked good, if a bit rich for Apple Bloom’s usual tastes. She–he was so active in the summer, and growing fil–colts needed all the oomph they could get.

Apple Bloom continued, “But I really promise I’ll be really– wait, did you say eyup?”

“Yup.”

“Thank you Big Mac!” the colt cheered, jumping up and prancing in a circle around the table, “Thank you! Thank you! Thank you! Thank you!”

“Just promise me, no funny stuff.”

“Anything we do will be the di-a-metric opposite of funny stuff,” Apple Bloom said, tearing at his bread roll with gusto.

“And no dirty, nasty things, alright?”

Apple Bloom just looked at him like he couldn’t believe what Big Mac was saying. And Big Mac couldn’t believe it either. He hadn’t in a million years thought he’d have to be dealing with a little colt in the middle of a heavy estrus season. Big Macintosh still didn’t know what to do about his sister Applejack, and her suffering.

Truth be told, that orange mare terrified Mac, with how her body was taking her over, and making her do things that she’d never want. He knew she was just a slave to estrus like any other filly, but to see it happening in front of him every year was just... it made him feel like Applejack was drowning in the ocean, and try as he might, Big Macintosh could not throw that life preserver far enough to reach her.

“We’ll be in the clubhouse the whole time,” Apple Bloom said, “It’s a meeting, not an adventure, so how would there be anything dirty or nasty? There ain’t no tree sap in there. And we’re not painting anything, I swear!”

Big Macintosh shook his head, saying, “No no, ah mean...” Celestia above how could he ruin a child’s innocence like this, just to satisfy his own paranoia. She–he knew about estrus, just like any other filly. There had been a class even!

“Remember that s-sex ed class you took?” he asked hesitantly.

“Uh huh?” Apple Bloom said neutrally, tilting his head.

“Well, that stuff,” Big Mac concluded, “Don’t do that.”

“What stuff?” the colt asked testily.

“Anything in that class,” Big Mac said looking aside uncomfortably. He didn’t want to even think about this subject, much less tempt his own groin into betraying his intentions to any mares who might see him. “What they taught you in it.”

Big Macintosh absolutely refused to believe that such a class would skip out on the basic consequences of sex out of wedlock. How it’s a one way trip to Tartarus and there ain’t no chances to get off the ride. He remembered the lessons his Ma and Pa—may they rest in peace—taught him about being true, and persevering even though your base instincts want to make you turn astray. They had been so blissfully married during the entire life in which he knew them, and Ma never had a problem with estrus, or got crazy about it one bit. Though things did get awfully noisy at night. But they knew the right way to live, and Big Macintosh was bound and determined to make sure his sister got to feel that kind of happiness.

His... sister, Applejack. Way, way, way too early to think about Apple Bloom getting married.

“Well, okay...” Apple Bloom said uncertaintly. Mac smiled at him and gave him an approving nod. Then Apple Bloom headed out for an early start to afternoon chores, so as to have more time with his friends. Big Macintosh got himself a nice chilly thermos full of a certain invaluable substance for a mare in estrus, as well as a bag out of the icebox, and a bucket.

With those articles born on his harness, Big Macintosh started to head into town after a certain orange mare, who he saw slinking off like a thief in the night. Slinking like a thief in the night, in the middle of the day, isn’t a very effective strategy, but Applejack wasn’t much of a mind to think about strategy this time of year. Or to think about anything at all. He knew she would hate him for this but, it didn’t mean nothing. It was just the estrus making her feel that way. She’d be thanking Big Mac after her estrus was over, and she was herself again, and hadn’t ruined her purity or gotten herself knocked up.

Chores for Apple Bloom were as natural as apple pie. It was just something she’d lived with her whole life, and she loved how she could help her family and make everypony smile with the things she did to help out. She rotated out some more of the spring crops for summer ones, going down the rows and tearing out pea stalks to dump ‘em in the threshing bag, leaving the dark brown soil afterwards with little tomato seeds scattered in it. The zucchini were starting to look ready too. The thought that she might see her friends this afternoon buoyed her spirit. She was even starting to feel that maybe this boy thing wouldn’t be one big long prison sentence. She really appreciated being able to enjoy herself, before Discord got back from his... thing.

As natural as her chores were, they weren’t as fun as what Apple Bloom had been getting into in her spare time. Curing estrus was pretty much the funnest thing ever. So she hurried through her chores, then gallopped up to the clubhouse most eagerly. She’d been holding out for the day, having more than prepared her nethers for boy stuff delivery. She even had to remind herself as she walked in, that this wasn’t about shoving a penis into a filly this time.

Well, not right away at least.

It was win/win for Apple Bloom, though. Either Scootaloo needed her help, when the boy stuff didn’t work, or Sweetie Belle could take Apple Bloom in, and not have to worry about Moon tea again. One way or another, Apple Bloom was getting inside a filly, and that suited her just fine.

On an intellectual level she was maddeningly curious if it would work. Did grownup ponies do this, to help carry over estrus more effectively? Could you do it with the extra that came out? Was Scootaloo going to like it? Or was it going to go like, her face was just going to fall sadly, before she yanked it out, and presented eagerly for Apple Bloom to do her right? As much as Apple Bloom wanted to see Scootaloo lifting her tail for her, she’d hate to see her disappointed, and the former result would be pretty amazing too.

Scootaloo was there at the clubhouse when Apple Bloom arrived, but Apple Bloom was still a bit over-eager because they both got there early, and had to wait for Sweetie Belle, then.

“So...” Scootaloo said casually, scraping a hoof on the floor.

“Yeah?” Apple Bloom prompted her.

“It’s gonna be so awesome,” Scootaloo gushed. “I’ve been thinking about it all day. I wonder how I’m gonna do it? We could be the first ponies ever to do this! Maybe I’ll get my cutie mark! In science vagina... boy stuff something.”

Apple Bloom laughed, “Ah don’t know what kinda mark that would be, but it does sound pretty awesome. If’n I still had a vagina I’d totally be sitting on a thing full of boy stuff. How are you doin’ anyway?”

Scootaloo grimaced, squeezing her legs together. “It’s been a while,” she said speculatively, “I’m definitely ready for some boy stuff. It’s stupid hot and wet back there, and every time I do that winking thing I ... remember you.”

Apple Bloom blushed a bit, saying, “Yeah, those memories get me going too. Ah may not have a vagina no more, but I have been looking forward to getting inside one. Sweetie Belle’s, or both of you if the decorator doesn’t work out.”

Scootaloo blushed too, saying, “You really like that, huh...”

Apple Bloom nodded emphatically, saying, “There’s just somethin’ so satisfying having my hips snug up against a filly, knowing that my penis is inside her. And putting boy stuff in, hoowee is that great.” She felt herself start to unsheath just from thinking about it, and also the amazing scent wafting off of Scootaloo’s hindquarters.

“Better than doing it outside?” Scootaloo said curiously, with a shiver in her rear.

Apple Bloom nodded, looking at Scootaloo thoughtfully, saying “Puttin’ it in the bottle was great, but when somepony is snug around me, and ah can feel her heat and wetness while it’s squirtin’ out of me, it just makes me wanna put it deeper and deeper.”

Scootaloo just whimpered in response, at a loss for words. There was a noticeable trickle running down her leg. Apple Bloom looked aside, then said quietly, “Hey, you wanna do it a little?”

Scootaloo started to nod, but then she said, “You can’t though,” in a sorely disappointed tone. “We’ll mess up the experiment, and then Sweetie won’t have any boy stuff when she gets here.”

Apple Bloom smiled confidently, saying, “Naw ah think I can gauge it right. It’s real obvious when ah’m about to go over. We should be fine if we’re careful. Sweetie should be here in a couple minutes anyway, so go ahead and stick your butt at me, an’ we can have some fun while we wait.”

Scootaloo only licked her lips once in hesitation, before getting a big grin that matched Apple Bloom’s. Spinning around, she presented her ass, her tail flopping up and aside. She whimpered as her hindquarters winked for Apple Bloom, making Apple Bloom’s shaft twitch in anticipation. “Here ah go!” Apple Bloom said cheerily, rearing up and planting on Scootaloo’s hindquarters. “Mmm, gosh,” she added sensuously, as she felt her penis mashing up against Scootaloo’s slick groin.

“Little higher,” Scootaloo said, fidgeting under Apple Bloom impatiently.

“Ah know,” Apple Bloom said, “Was just enjoyin ya. Hold on, ah’ll just...”

“Ngh–got it!” Scootaloo crowed quietly when Apple Bloom started to sink into her. Soon as it happened, Scootaloo started to push backward, in forceful rocking motions, until her groin was grinding up against Apple Bloom’s balls. “Deeper and deeper...” she smiled distantly, rocking her body to slide Apple Bloom in and out.

“Mmn... mah gosh...” Apple Bloom murmured, hooking her hooves around Scootaloo’s hips and pulling them firmly to hers. She could feel Scootaloo all around her penis, that moist oven caressing her sensitive flesh. She felt like she was going to do it right now, though past experience indicated she’d need a lot of thrusting still.

“Feels... good, huh?” Scootaloo panted, her sideways smile not visible from where Apple Bloom had mounted the little orange pegasus from behind.

“You feel so wet in there, Scoots,” Apple Bloom said a bit sappily, hugging the pegasus’s crotch to her own. “Makin’ me want to make all sortsa boy stuff.”

“All that boy stuff, in there...” Scootaloo said dreamily. Her vagina convulsed around Apple Bloom’s penis, and Apple Bloom was thrusting before she even realized it, Scootaloo giving little hot cries, almost coughs with every thrust. Dragging herself to a halt so as not to actually start doing it, Apple Bloom leaned against Scootaloo saying, “Can ya feel me in there?”

Scootaloo actually paused at that instead of answering right away. “You feel incredible,” Scootaloo said hesitantly, her thighs twinging as she tried to pinpoint the feeling. So without moving any more, Apple Bloom just twitched her penis in there, like she was trying to slap her belly except she couldn’t with it stuck inside Scootaloo. Scootaloo’s response was, “I think I can–yes yes I can feel you ohmygosh you’re in there you’re really in there!” You can probably tell the point in which Apple Bloom started doing her little penis trick.

Apple Bloom pulled her hips back, sliding smoothly out of Scootaloo’s vagina, and Scootaloo pushed back herself, sliding Apple Bloom back inside. Then Apple Bloom pushed forward, forcing the pegasus’s straining hips back forward and burying it deep inside her. They kept up smooth slow strokes like that, both of them unable to really make words at this point. Apple Bloom just loved the feel of Scootaloo, and likewise Scootaloo, Apple Bloom.

They didn’t even notice when Sweetie Belle came in, at least not until she exclaimed, “Hey!” in a bright angry soprano.

Apple Bloom actually didn’t even stop thrusting, just turned to face Sweetie and said, “Oh, hey Sweetie. We were just havin’ some fun before you got here... as you can... see.”

“Well knock it off,” Sweetie Belle said irritably, sliding her magically enhanced lunchbox across the floor. “You’re gonna make boy stuff in her, and it will ruin everything!”

“Okay, okay,” Apple Bloom said, stopping thrusting. It was unexpectedly difficult to do so.

Scootaloo’s shoulders were hunched as she panted out sheepishly, “Yeah... guess we kinda... I wouldn’t mind if you did boy stuff in me now, but it’s Sweetie Belle’s turn.

“You’re gonna be just like me,” Scootaloo whimpered hotly to Sweetie Belle, her hips spread wide by Apple Bloom’s shaft, “Apple Bloom is gonna be inside you just like this, and putting all sorts of boy stuff in you... it’ll all come out and be messy...”

Sweetie blushed at that and her own tail twitched up. “Y-yeah,” she agreed quietly. “But um...” she nosed in between their groins, making Scootaloo squeak by poking insistently, and a little curiously at Scootaloo’s distended entrance. “Not if you keep doing that,” Sweetie said critically.

Scootaloo murmured unhappily, and grumbled, “Okay, fine.” Apple Bloom reared up again when Scootaloo’s legs tensed, and she stood there breathing hard while Scootaloo walked off of her shaft, both of them dropping down and gasping when Apple Bloom’s penis swung free.

“Ohhh man,” Scootaloo moaned, sinking down onto the clubhouse floor, “I forgot how so freaking crazy that feels.”

“You forgot what a penis feels like?” Sweetie Belle squeaked. Scootaloo shook her head, and said, “No, I mean, when it comes out. I just want to jump on her and get something in there right away and it’s just it’s like jumping into a cold pool and and I don’t want to be empty!”

Sweetie nodded in understanding, and Apple Bloom nodded in ...less understanding, and Sweetie Belle put a hoof on her lunchbox, saying, “Well you’re in luck because that’s just what we’re going to do!”

Once the three of them were together and, relatively coherent, Apple Bloom set the alarm clock at about 10 minutes before they had to worry about leaving, so they wouldn’t be too late. Sweetie quickly took out a milk bottle, full of its precious cargo of experimental Grade A Apple Bloom boy stuff. Apple Bloom held the cake decorator, with its plunger removed and open container facing upward. Into it, Sweetie poured the boy stuff.

Sweetie had to get on twos to tilt the milk bottle, patting the bottom as the stuff came out thick and gloppy. Thicker than Apple Bloom remembered, but then it had been chilled. The little enchantment on a lunchbox wasn’t good enough to freeze anything for sure, though very effective at keeping already frozen ice packs cold, but it could definitely make something milky a bit thicker and colder. She snickered a bit at the thought of Scootaloo being more than hot enough to warm this thing up.

“What’s funny?” Scootaloo asked, dancing on her hoof tips as she watched the two prepare her special treat.

“Oh, just thinking about how much you’re gonna squeal when you stick this thing up your vagina,” Apple Bloom snarked, “Like sticking your hoof in cold water, except opposite.”

“I am not squealing!” Scootaloo protested, “It’s gonna be totally awesome, and besides I’m so freaking hot down there. We sit on ice packs so if anything, I bet it’ll be nothing but refreshing.” She tossed her mane while saying so, giving a confident smug smile.

“Alright, how are we gonna do this?” Apple Bloom asked, balancing the sealed syringe on her upturned hoof.

“Give it to me,” Scootaloo said, reaching her hoof out, “I want to see if I can do it, totally solo.”

“Good idea,” Apple Bloom nodded, “We’ll just sit and watch, in case you can use any assistance.”

Sweetie Belle ummmed, and said, “We could do that, or we could get ready for... for my turn.”

Apple Bloom looked at her, but said, “Sure. Ah can lick you, and maybe a little goin’ inside. I can’t exactly orgasm in you until our little experiment’s done though.” Sweetie nodded sadly, turning to look at her own heated hindquarters. Apple Bloom tossed the syringe at Scootaloo, who caught it easily. “So hop to it, Scoots!” Apple Bloom cheered, “Sweetie’s butt is counting on you.”

Sweetie blushed and looked forward, while Scootaloo grinned sloppily, more at the dessert decorator than at Apple Bloom. As the two of them watched hopefully, Scootaloo lay back against the wall, with her legs spread to allow her labia open to the warm summer air. She had been ejaculated inside twice now this season, and her body was already ready for more. And Scootaloo was ready to give it just what it wanted. Well, almost what it wanted. This decorator she held was a lot stiffer than a penis, and couldn’t exactly flare so she’d just have to do all the flaring inside on her own.

“When are you going to push the plunger?” Sweetie asked curiously, before Scootaloo even had so much as touched her own vulva.

Scootaloo just stared thoughtfully for a second, then a smile crept on her face and she said indulgently to Sweetie, “I’m going to do it... right when I orgasm. Put the boy stuff in me...”

Scootaloo started stroking her labia with her hoof at those words, feeling them awaken so quickly and eagerly in this estrus induced state of hers. She heard herself giving lustful, satisfied moans without even trying, because of estrus. She found herself shifting so her friends could see what she was doing better. She wanted them to see her sliding her nail up and down the edges of the fleshy cushion that marked her inside place. She didn’t just have labia there; she had an entrance, a gateway leading deep inside her.

The liquid smearing over her hoof only made the job easier. It was like getting goosebumps, and then every inch of you in there was just dripping with wetness. Scootaloo loved how it trickled out and smeared all over. It wouldn’t be long before she could–

wink

–get at her clitoris yessss. Scootaloo humped her hips up when her innermost vulva lifted and spread, making her clit press so deliciously against her frog. She gave a loud moan at the pressure her loins made on her hoof’s surface as she strained to press them against her strongly. She could practically feel herself just opening up inside her tummy, expanding in there, as if her body were preparing itself to take things inside of it. Her friends were watching her, but Scootaloo didn’t need to care how loud she moaned. They loved it when she did that, and she knew it.

“Mmm, Just about ready,” Scootaloo murmured huskily, letting her hoof slip away, revealing her burning wet petals with little care or restraint. Sweetie Belle and Apple Bloom both seemed to be captivated by that thing between her legs, and Scootaloo arched up, pulling her tail away with her own hoof so they could see her better down there. So they could see everything that she was feeling. It wasn’t just Apple Bloom who was enchanted by her, but Sweetie Belle too, blushing hotly as she gazed into Scootaloo’s aroused display. Reaching for the decorator almost lazily, Scootaloo felt an eagerness bubble up in her as she realized it was really going to happen. She could put this whole big thing in her, and nobody would judge her or call her bad, and it made her feel so awesome that she could do it.

So without further ado, she nestled the decorator, nozzle-first, into her folds. They’d of course removed any sort of sharp cake decorating attachments, so hopefully it would still work without an unpleasant pokey thing catching her in there. There was just the broad flat tip smushing against her... broad and flat like Apple Bloom got, albeit even in diameter. Gripping it with her hooves, Scootaloo said, “Okay, here goes...” a little nervousness creeping into her voice. But Scootaloo was not one to be a nervous pony. She didn’t hesitate, and just started jamming it up into her labia, trying to get herself to wrap around it, so she could push it inside. She grunted and wiggled, her edges, the edges of the entrance in her body catching deliciously. Yet it was difficult to surround the whole tube in the circumference of her entrance all the way around. It would catch in one side, but slip out on the other side.

She finally figured it out by stretching her labia apart with a hoof, then using the other to wedge the decorator in there, then stretching on the other side. If she got it around the edge, and it felt so good to stretch that, then she could—boy it really did feel good. Just got to catch it around, a little bit more, push more firmly...

“Got it!” Scootaloo exclaimed, as the decorator slid just enough into her slippery canal. She stopped pushing then, and just bubbled with a laugh, looking at the cylindrical thing jutting out of her, and then to her friends, smiling cockily at them. “And now, I will make this dessert decorator... disappear!” Scootaloo announced theatrically. Nobody really laughed, but Scootaloo didn’t care. Her labia felt too good to stretch, for anything to upset her at all.

Scootaloo gripped the edge of the cannister with her hooves, definitely avoiding the plunger for now, and pulled strongly. To her delight, the dessert decorator slowly descended into her. It was... it was way bigger than Apple Bloom’s penis, now that Scootaloo could feel its girth. It hadn’t looked bigger, but it was... it was stiffer, and that was stretching her more. Scootaloo had to pull as hard as she could to get it into her, and she did it enthusiastically. She winced at the feeling of her canal stretching breathlessly, even maybe a little teeny bit painfully. But she loved it, and she wanted that little pained stretchy ache, and the deeper she felt it the deeper she wanted it. Just like when Apple Bloom went into there.

Scootaloo inhaled suddenly as she bottomed out. She couldn’t believe it at first. There was almost no decorator left coming out of her, besides the very end, and the plunger. Wiggling around the decorator to feel herself in there, it felt sort of like she had a cup in there, and the back of it stretched just like the sides did, but allowed no further passage deeper within. It wasn’t quite just simple uniform flesh in there; sometimes when she wiggled right, she’d hit something really sensitive. She couldn’t get it any deeper though.

But man, that was more than deep enough. Scootaloo’s whole feet were braced to spread her thighs wide. Her body was slick with sweat, and another laugh was bubbling up in her. She just couldn’t believe how good she felt. “This is so amazing!” Scootaloo shouted heartily, leaning back on her elbows and tilting her head back, arching in front of her friends with her labia distended obscenely, hot and flushed and red, and wrapped tightly around this this thing.

“Feels better than a penis?” Apple Bloom said, with no small amount of surprise in her voice.

Scootaloo paused, and shook her head, “N-no it’s not the thing it’s... I mean... look at me!” she said waving a hoof over herself, “Look at this!” she said pointing at her groin. “I I I can put things into me~” she moaned, “And it changes m-me into... into wanting it and... and you can see me and I’m not even hiding and I love how you can see it.”

Apple Bloom nodded understandingly, saying in a husky tone, “You bet, Scoots. You look so... amazing, I don’t think I could hold back, if you didn’t already have a big tube full of boy stuff in you.” That made Scootaloo moan, as a convulsion went through her vagina. When her insides squirmed around it as if to grab ahold of it, the geometry of that cylinder in there stood out in stark detail in her mind’s eye. She had no control over the contractions when she was this stretched out; all she had to do was sit there and enjoy it, as every little wiggle made her vagina writhe with joy.

Sweetie Belle started to move forward hungrily, her eyes fixed on what was happening to Scootaloo down there, and Sweetie’s own soft vulva dripping with unconcealed arousal, but Scootaloo held up a hoof, gasping out, “No–! No, I have to do it without any help. That’s the...” she let her hoof slip to her clitoris. With her entrance so gloriously stretched, it smooshed Scootaloo’s clitoris up, and presented it right for her to mess with. Scootaloo couldn’t have winked if she wanted to! “Experiment...” she managed to finish, hot breath after hot breath filling her lungs as she pressed her hoof on the side of the cylinder, stretching herself with it while offering her frog perfect access to press slimily against her clitoris.

“I-it’s not just your labia, Scootaloo,” Sweetie Belle said in a captivated tone. “Your whole body it’s... you look so ...alive!” She shivered with restraint, just as much as Apple Bloom, leaving Scootaloo with no idea whether the actual colt, or the filly watching her was more glad to see Scootaloo in this state.

“Want to touch you so bad...” Apple Bloom said distantly, just looking at Scootaloo with an expression of open longing. Sweetie Belle began stroking Apple Bloom’s side in response, leaning into her. Neither were willing to stop watching Scootaloo though, so they couldn’t even kiss, or get heavier into each other. All that was secondary in priority to the moaning bucking writhing pegasus in front of them, that Scootaloo was. Scootaloo teased her orgasm forth with a singleminded determination, every flex and twist around that cylinder just making her feel so full and open and stuffed. She couldn’t even close her legs. She didn’t want to close her legs. She wanted to show them, wanted to show herself when she took Apple Bloom’s boy stuff into her.

With her soaked lips wrapped around the thick cylinder, Scootaloo leaned back with an intense look on her face, frogging her slippery clit as the heat induced estrus rushed her climax upon her like a speeding train. Her lust soaked mind could only think how she had it in her. She had the stuff, the secret boy stuff, it was already in her. She just had to push the plunger, and just– just thinking about it was making her hips explode. Sweetie Belle and Apple Bloom were still watching her hopefully. Scootaloo moaned as she thought about how Apple Bloom was watching her. Scootaloo had Apple Bloom’s boy stuff inside her, just waiting to squirt into Scootaloo any time she ever wanted, and Apple Bloom would see her do it.

Scootaloo tried to grasp the plunger clumsily, as the tube jerked back and forth in her convulsing cunt. It was happening it was–! She just–. She just stared helplessly at the cake syringe embedded in her hips, watching herself orgasm, unable to do anything besides shudder there hunched forward, clutching the mat underneath her and throbbing, deep inside her inconspicuous belly, all around that hot, stiff, wet cylinder. Scootaloo loved that cylinder. She loved Apple Bloom’s... oh Celestia she loved her cunt so much! It was doing it to her! She couldn’t stop it! She swam in pleasure, and her cunt was giving that to her again and again. Why had she been blessed with this beautiful thing inside her! She loved and she squeezed and she loved it for squeezing so amazingly.

When Scootaloo could think clearly again, she gasped raggedly, lifting her head up to look at her friends saying sadly, “I–I tried but I couldn’t move. I just... it felt so good.”

“It’s not too late!” Sweetie Belle said, “Remember the boys did it after you orgasmed too!”

“Yeah,” said Apple Bloom, “Go on, give it a shot! I’m ready for you if it don’t work.”

More compelling to Scootaloo than their encouragement though, was the hungry itch radiating from her vagina, making her fur stand on end. She was so tense. It made her want a penis there, just like this cylinder, but hot and fleshy and smooshy yet firm and flared. But before she could have that, Scootaloo had to at least give this a shot. Fillies were counting on her! So Scootaloo almost reluctantly laid a hoof on the plunger and depressed it hesitantly, making a little bit squirt in her just to feel it.

Her cunt rippled, and her wings snapped up with the need to fly as the stuff changed her in there. It was working! It felt amazing, smearing and sliming in there, warmed by the time it spent in her hot passage. Scootaloo was so thirsty, her cunt needed it so bad her hind toes were curling. Almost as soon as she tested it with the plunger, her other hoof shot down, using both hooves and bearing down gravidly on the tube, squirting it inside her as fast as she could. Scootaloo couldn’t have stopped if she wanted. She ached to make sure every female inch of her in there was covered in it. It was an entire colt’s ejaculate, so it had to be enough to top her out! She writhed around it, trying to squeeze so tight that it squirted out of her, pumping herself full as she could possibly be.

Scootaloo cried out wetly, as the contents of the syringe she was so forcefully pumping into herself started to spurt out the edges. She arched up, tilting her hips back so that the fluid ran down her groin in all directions from there, all directions from her cunt. Her bucking cunt felt so good it was all over her she–

She felt the plunger hit the bottom of the syringe, with a twinge of almost disappointment. “Almost” because, although she couldn’t keep pumping her vagina overfull of the stuff forever and ever... it got her. It worked. She didn’t feel even a twinge of the hot need that followed her orgasm so dreadfully. Scootaloo just felt gentle warmth between her thighs, her insides fluttering around the cylinder, no longer needy but simply exquisite. The relief was radiating from her groin, just like when Apple Bloom really did it. Scootaloo cracked her eyes open with a smile, leaning back on her elbows, the messy syringe still embedded in her hips, her legs spread wide to show them the incredible thing it had done. It worked!

“It worked!” she tried to crow to the heavens, but it only came out as an immensely relieved sigh. She just sat there, a fuzzy feeling welling up in her chest, smiling coyly at her friends who cantered forward and expressed their gladness, welcoming her for what she did to her own wet, messy, stretched, dribbling beautiful cunt.

Scootaloo lifted her head at a curious prodding on her abdomen. Sweetie Belle was there, her well groomed, delicate, white hoof depressing into Scootaloo’s belly. “Having fun there?” Scootaloo quipped.

“I can feel it!” Sweetie said in a shocked tone, pressing more firmly against Scootaloo. She could... wait, her prodding did feel like it was pushing against Scootaloo’s insides still wrapped around that cylinder.

“Really?” Scootaloo squawked, sticking a hoof forward and pushing at her own abdomen. It was true! You could totally feel a place where Scootaloo’s belly wasn’t soft underneath, and conformed to a stiff cylindrical shape. “Apple Bloom, check this out!”

“Woah!” Apple Bloom said when her own hoof found she shape hidden in Scootaloo’s abdomen. It was silly they were all feeling Scootaloo’s abdomen and it was the weirdest situation ever, but for some reason Scootaloo was just... totally okay with it! She had boy goo inside her, and that’s what mattered. Everything else didn’t seem worrying or alarming or scary, as long as she was goo’d in there.

“Can you feel mah hoof from in there with yer vagina?” Apple Bloom said curiously, depressing experimentally.

“Sorta,” Scootaloo said in an explanatory manner, “I can feel it getting pushed against the decorator, but I can only tell it’s your hoof by looking.”

“You realize what this means?!” Sweetie exclaimed suddenly.

Both looked at her. Scootaloo offered hesitantly, “That... there’s actually a vagina in me, and not an extradimensional portal to Elsewhere?”

Both looked at Scootaloo. She shrugged helplessly, still laying there belly up. Couldn’t really maneuver very flexibly with your cunt stuffed full of a stiff tube after all.

Sweetie turned to Apple Bloom intensely and said, “It means that I can get your boy stuff,” in a luscious tone, half lidding her eyes and stretching her neck up to Apple Bloom’s face. She turned her posterior to face Apple Bloom, and lifted up her tail, wiggling her butt like she was teasing Apple Bloom, saying “Alllll in here!”

“Woah, Sweetie!” Apple Bloom said in surprise backing up a step.

Sweetie just scooted her butt forward, well backward, saying in an exaggerated voice, “Arrrr I’m going to swallow you up.” She wiggled her butt like it was talking saying, “I am the labia monster! Give me all your boy goo! Arrrr!”

Scootaloo found laughing wasn’t exactly comfortable with something jammed up so deep it practically hit your diaphragm.

Sweetie Belle giggled and rolled on her back, wiggling her hooves in the air like she already had boy stuff inside her. “I’m just so happy!” she cried sweetly, “It worked for Scootaloo and now we both get to overflow and get all gooey, and whose penis is going to do it both times? It’s Apple Bloom!”

Apple Bloom laughed too, saying “Sweetie you really have a way with words, you know?”

Sweetie gave no response, simply rolled to her feet strutting around happily and stuck her butt up in the air again expectantly.

After Scootaloo’s little show, Apple Bloom had no trouble getting inside Sweetie, not even hesitating to mount up and stick it in her. “Ohh yes!” Sweetie squealed, rocking back eagerly as Apple Bloom came down on her and she got filled in a single stroke all at once. After Scootaloo’s little show, was no way Sweetie Belle wasn’t more than ready to be filled. But as the two eagerly began bucking against each other, Scootaloo raised a hoof.

“Hey, wait! Wait a sec, girls. Could you uh... hello? Could use some help here? Pull off a sec and help me get this thing out! Girls?”

Scootaloo had to figure, she was going to get no response for the next ten minutes at least, if she just sat there. They were just that into it. So Scootaloo fiddled with her own groin, hooking the edge of the tube. There was no grip to pull it out though, not the way there had been an edge to push it in. When she realized it was going to take about as much force to get it out as put it in, Scootaloo started getting worried. There was no way she could get her own teeth down there. Man, who designed these things?

Scootaloo swiveled her legs around, wincing at the stiffness where she expected fleshy flexibility. She managed to roll stiffly to her feet, waddling over to the two, then rearing up and leaning an elbow all casually on the back of the rocking unicorn, looking up at the thrusting earth pony wryly.

“Hey Romeo!” Scootaloo said loudly, “I need some help here!”

Apple Bloom tilted her head down to look at the pegasus uncomprehendingly. Then Apple Bloom’s eyes widened and she shuddered a gasp, dragging to a halt, causing Sweetie to give a needy animal whine. “Did ah just...” Apple Bloom said, looking at the unicorn she was penetrating in astonishment, “Ah didn’t even mean to I just didn’t even think and... wow, Sweetie.”

“Thinking is overrated,” Sweetie said grumpily, grinding up against Apple Bloom’s pelvis.

“Still Sweetie,” Apple Bloom said, just rocking in and out of her shallowly to maintain their arousal. “Scootaloo needs something.”

“Yeah, I uh...” Scootaloo’s ears went down abashedly, “I need somepony to bite this darn decorator and pull it out. I can’t get a good grip with my hooves.”

“Oh gosh Scootaloo, I’m so sorry!” Sweetie exclaimed in surprise, turning her head to the pegasus, who’d lowered from Sweetie Belle’s back to stand, stiffly, beside them. “I was just... thinking it was my turn,” Sweetie said apologetically, “A-and I didn’t even think you’d need,”

“It’s okay, Sweetie,” Scootaloo said, patting her on the head. “Just pull this thing outta me and you two can get going again.” Sweetie nodded vaguely, and her eyes went distant, her face filling with emotion as apparantly her insides contracted around Apple Bloom.

“H...hurry it up, Sweetie,” Apple Bloom said tensely, holding tight to her hindquarters, “I wanna get started so I can squirt in you already.”

“I bet you want to feel her heat and wetness around you, while it’s squirting out of you, huh?” Scootaloo said teasingly. Apple Bloom didn’t blush though, just moaned and rocked shallowly against the increasingly panting unicorn, who seemed to feel Apple Bloom more, the longer she was inside her. Scootaloo hurried around though, before her friends got lost in bucking again.

With the plunger fully depressed, it was a simple matter for Sweetie to bite down on the rim of the decorator’s container. Then Scootaloo just walked forward from there. She stumbled the first step because it was really in there. She had to brace on the floor and walk forward to get that slimy cylinder to slide out of her stretched passage. It was actually... kind of cool how hard Scootaloo’s vagina was clinging to the thing. It just felt good to stretch everything down there, every which way. But at last it, and a good amount of Apple Bloom’s seed plopped out of her, while Scootaloo heaved a surprised gasp at the feeling.

“Wow, I feel empty,” Scootaloo said, looking at her hips somewhat bemusedly. “Am I still ...open down there?”

“Yeah you...” Sweetie said dully, her attention on not much else besides thrusting and lust, “You could see all the... really deep...” and then her tongue was on Scootaloo’s labia.

That squeezed Scootaloo up real fast, her hips hiking in the air as the unicorn’s tongue caressed her loosened labia. “You taste like Apple Bloom,” Sweetie said dreamily, continuing to suckle at the third teat, so to speak. Scootaloo loved that unicorn’s tongue, and was soon bucking into her lips, as much as Sweetie was being bucked into hers.

Sweetie stopped licking and cried out loudly, and just leaned on Scootaloo’s butt when she started to orgasm. Apple Bloom grimaced as Sweetie Belle did it in there, but Scootaloo was in a position to face Sweetie Belle. She cradled the unicorn’s head gently, while Sweetie stood there, helpless in her orgasm. So quiet on the outside, but Scootaloo knew from her unfocused expression that Sweetie felt a storm within. It felt good to be close to Sweetie when she was orgasming. Sweetie just felt so vulnerable, and precious in Scootaloo’s hooves. When Sweetie’s hoof came up shakily, clumsily, uncoordinatedly, to try and hug Scootaloo back, it made Scootaloo feel like an anchor for Sweetie Belle, or a lifeline, and she liked that feeling.

The pause was enough for Apple Bloom to come to her senses, to a degree. Watching the two cuddling, from her vantage point atop Sweetie’s back, she felt a twinge of envy penetrate her cloud of lust. Apple Bloom pulled out of Sweetie in a smooth stroke, dripping and jerking and pink, though not flared.

“H-hey you two ah was wondering,” Apple Bloom said almost in a whimper, her twitching penis making her look oddly vulnerable the way she had to hunch over it sensitively. “I don’t suppose we could do it so... so ah could kiss too?”

Sweetie’s immediate wink was more of an answer, than the unicorn could probably have given with words. But then, she probably would have agreed to anything if it meant getting a penis inside her at this point. It was kind of hard to tell how much of it was your tender feelings for your friend, and how much of it was just a raw, animal need that your friend could provide for.

Sweetie was unsurprisingly amiable to doing it “The Scootaloo Way.” Apple Bloom lay against the pillow, well the protective mat on the pillow, pressed up against the wall. Sweetie climbed atop the colt laying there, and eagerly slid Apple Bloom inside her again, the penis vanishing in the unicorn’s soft hips as Sweetie’s wet heat surrounded it once more.

Apple Bloom didn’t even fully perceive how lonely her lips were, until the penetrated Sweetie Belle leaned down and brought her lips to kiss against hers. Apple Bloom moaned into the kiss, surprised at the feeling it evoked, and without even breaking it, Sweetie’s hips gyrated, sliding her penis in and out of that fleshy pocket. Apple Bloom felt connected on both ends, like there was a circuit of pleasure between her and Sweetie. Not even able to think, she pushed hungrily against Sweetie’s lips, breathing through her nose and thrusting back against the unicorn, filling that Sweetie up deep with the penis she was given.

Sweetie’s hips joined with Apple Bloom’s in a steady rhythm, stroking Apple Bloom’s senses wild. Sweetie didn’t have any problem at all pistoning that way, since she was really gosh darn horny: enough that her hips moved all on their own, in that instinctive humping motion, singlemindedly aimed to fill themselves with seed. Sweetie did have some trouble kissing while thrusting though, since Sweetie had to breathe through her nose, and needed to pull back gasping occasionally from the stimulation exciting her body. She ended up alternating between sliding that cock back and forth in her passage, and jamming her hips still against Apple Bloom’s, kissing Apple Bloom with a ferocity the earth pony clearly hadn’t expected, but certainly wasn’t complaining about.

They were enjoying themselves so much, and Scootalooe’s insides were just fine, but she was watching Apple Bloom’s penis gleaming in the air, for the moments before it vanished inside Sweetie Belle again, and Scootaloo was just... well it probably wasn’t an unreasonable request, was it? But she had to hurry and ask it, because with the gasps Apple Bloom was giving, Scootaloo’s window of opportunity was closing.

“Hey, I uh, hey guys, hold on a second!” Scootaloo nudged Sweetie Belle who reluctantly stopped the reckless pistoning that was making her close her eyes, and gasp, and toss her curls around heedlessly.

“I know this is kind of weird but,” Scootaloo said hesitantly, crossing a hoof in a way she so rarely did. “I did get your boy stuff Apple Bloom, and I feel amazing, but I didn’t get to feel your boy penis.”

“You sure got that tube stuck in you though,” Apple Bloom said somewhat grumpily, rolling her eyes.

“Yeah, but I was hoping that before you orgasmed in Sweetie Belle, that you could...” Scootaloo huffed, trying to find the words, “Put it in me a little more? N-not to orgasm or anything, I mean. I just want to feel you in there, just a few times, and then you can put it in Sweetie Belle, and put all your boy stuff all in her, and spilling out and stuff.”

“...maybe there’s a basis to this,” Sweetie said contemplatively, calmly straddling Apple Bloom’s crotch with nary a penis in sight between them. “Maybe to cure estrus you need boy stuff, and a boy penis.”

“Aw, I hope not!” Apple Bloom said, squirming stiffly against the wall Sweetie pressed her up against. “After all that effort. Is your estrus still bothering you, Scoots?”

Scootaloo looked back where her groin was all messy with the white goo that Apple Bloom made, and most of it was way deep up inside her. She shook her head, saying, “No, it’s not! It’s just like when you really did it. I feel great. I just... I dunno maybe I just ... maybe I just like your... penis?”

Scootaloo turned and presented without even thinking about it, saying, “Sure that decorator was fun and all, but it wasn’t a penis. It felt way different, and I just... kind of... miss it.” She shivered in place, not really sure if she came off as a weirdo, or was just being rude.

Sweetie walked next to Scootaloo then, and smiled, caressing her cheek with a hoof, just like Scootaloo had done to her while Sweetie orgasmed earlier. Wait, when did she–! “Go ahead Scootaloo,” Sweetie said in that voice so full of love. “I know you’ll stop before it happens, because you know I need it, so you can enjoy yourself.”

Scootaloo turned, and saw Apple Bloom lying there with a semi-confused expression on her face. Apple Bloom’s naked penis was just hanging there out in the open air, while the pony beneath it with those ruby red locks and lemon yellow fur gave her an uncertain smile and saluted jauntily. Sweetie Belle was standing beside Scootaloo, just heaving with lust, a steady trickle running down her leg, and yet in all that she was still looking at Scootaloo encouragingly.

“Thanks, girls,” Scootaloo said, her chest shaking with more emotion than she’d thought she was feeling. Scoots climbed atop Apple Bloom and straddled her hips, trapping that cock in between them. It was so warm against her vulva. It pulsed, not the pumping pulses, but just the gentle beat of Apple Bloom’s heart. Wasting no time, Scootaloo stilted her hind legs up, maneuvering the penis with her hoof until it lined up, and then sank down on it with a satisfied sigh as her insides hugged around it.

Scootaloo didn’t even bounce. She just sat there and felt Apple Bloom in there. She stroked Apple Bloom’s chest fur, the delight in her stirring her emotions like a cauldron. She didn’t even realize she was crying until the tears started to hit Apple Bloom’s chest.

“Are you okay, Scootaloo?” Apple Bloom said worriedly. She said worriedly. She had a penis and it was stuffed up into Scootaloo, and she wasn’t just trying to use it. She was still saying things worriedly, with actual concern.

“I’m fine I just,” Scootaloo mouthed, trying to figure out why it was so hard to breathe evenly, “You are the best friends I ever–” and she just choked back a sob then. Why was she crying? This was the most wonderful thing that ever happened to her!

Scootaloo stood up, Apple Bloom’s penis extending from her well worked vagina like a smooth piston, then walked forward the last bit, and climbed off of Apple Bloom, saying, “Y-you can finish now Sweetie.” She couldn’t look at them or they might see her. She felt like she was going to fall off the shelf and shatter into a million pieces. Taking a deep breath, she lifted her head and looked at Sweetie Belle giving the unicorn a genuine smile. “I’m satisfied.”

Yeah, there was no way Sweetie Belle was going to so much as twitch after a breakdown like that. “C’mon Sweetie,” Scootaloo quipped, “Who’s the one in heat here, you or me?” She rubbed at her eyes saying, “I I don’t know why I’m crying I’m not sad it must just be the estrus messing with me.”

“Scootaloo...” Sweetie said wistfully.

Scootaloo smiled again, holding her head straight and walking up to Sweetie. “I’m fine, Sweetie. But you’re not. Don’t you remember?”

Sweetie opened her mouth to retort, but Scootaloo reared up onto Sweetie’s back from the side, curling her hooves over Sweetie’s thigh shouting, “Your labia monster must be fed!” Sweetie squealed and tried to buck Scootaloo off reflexively, but Scootaloo had a hoof wrapped around her tail, and used the other to tickle Sweetie’s vulva shouting, “Arrr, a sacrifice it demands! Boy stuff in every corner!”

The alarm clock went off.
