Apple Bloom just rested her head on her front hooves as the two fillies in front of her whispered back and forth at a volume that wasn’t effectively hiding anything at all.

“What do you mean great?!”

“What do you mean what do you mean?”

“We’re supposed to study with him?”

“Well yeah, eventually.”

“If you didn’t notice we’re both in estrus right now!”

“That’s why I brought him here.”

“That is the worst possible idea!”

“Oh is that so?”

Dinky paused in the whisper tirade to look at Apple Bloom. Well, look being an understatement of what Dinky’s senses were doing. Her nose flared inadvertently, and then her pupils narrowed. Apple Bloom blushed, and crossed her hoof, backing up a step to try to give her some space. Guess Dinky’s smell wasn’t the only one in the room anymore. The two returned to whispering.

“He’s going to set me off!”

“You’re not a bomb, Dinky.”

“Tell that to my bottom!”

“He’s gonna help you, Dinky.”

“How could he possibly help?!”

“He‒”

“You think I can study with a colt in the room?”

“He‒”

“I don’t care how good he is. Now it’ll take the entire afternoon just for me to cool down!”

“Dink‒”

“Oh Celestia I’m already starting to think about his penis.”

Apple Bloom cut through the whispers with a steady, “Uh, excuse me.” Both fillies’ gazes snapped to her. “Ah think Archer is tryin’ to tell you something, miss Dinky,” she suggested, waving an uncomfortably colty forehoof. It was really uncomfortable to be a colt entirely at the current moment, in fact. Apple Bloom was never this boy crazy, was she?

Yeah. Don’t answer that.

Dinky didn’t listen to Archer, but then began to address Apple Bloom directly, standing there squarely with her short legs spread apart, speaking in an ingratiating and absolutely nerve wracked tone. “I’m terribly sorry for the m-mix up, mister A-Apple Bloom, but we’re going to... to have to call this o-off. Archer and m-me are in h-heat r-right now you see so, so we c-can’t study with our uh with uh... between our... terribly sorry, I mean”

“Dinky,” Apple Bloom said, cutting her words off with all the compassion of a mercy killing. “Ah can cure your estrus.”

The room seemed to shrink around Dinky. “...what?” she said at last.

“Your estrus,” Apple Bloom repeated, “I can make it gone.”

She frogmouthed in shock for a second then her face twisted with disbelief, “No you can’t, stop teasing me,” she said in a clear, bell like voice.

“I can,” Apple Bloom insisted, “Any colt can who knows the trick. It’s easy and fun.”

Dinky was silent, if defiant looking, so Apple Bloom asked, “Archer didn’t tell you, did she? That I was a colt, and that I could y’know... help you study.”

Dinky just shook her head dumbly.

Apple Bloom looked right to Archer admonishing the blue pony. “I can’t believe you set her up! Estrus is a serious problem, not something you can joke about.”

“But... but... did you see the look on her face?” Archer said earnestly.

“Ah did and it was freakin’ me out,” Apple Bloom grumped, “She runs up to the door expectin’ to see a filly and right in full on estrus comes face to face with a colt. That’s just mean.”

“It was my only chance!” protested Archer, “My only other friend is Scootaloo and she was the one who did it to me!”

Apple Bloom blinked and said, “Whattya mean by that?”

“She s-sort of surprised me with the... the whole colt thing and... I really enjoyed it...”

“Well just because she did doesn’t mean you have to. Look at Dinky here, she’s practically dripping!” Apple Bloom gestured with a hoof, then winced not meaning to insult the poor pony.

“I... I... I I need some tea,” Dinky said, trotting for the door. Apple Bloom let her go, but then looked at Archer wanly, saying,

“You gotta go after her. She needs your help.”

“But...but what can I do,” Archer said looking a lot more miserable than when she started this whole “prank”.

“She trusts you, Archer,” Apple Bloom emphasized, “You pulled one on her you shouldn’t have and that trust is shaken, but she still trusts you. You gotta tell her to drop that tea and come up here, and that I’m here to help. Go on, you can do it. You’re her friend.”

When Archer crept down the stairs she could hear a clinking in the kitchen already, and the hiss of a tea kettle. She carefully made her way into the kitchen, though if Dinky noticed she made no sign of it. Next to Dinky was a brewing tea kettle and a box of the tea that every filly this time of year comes to be intimately familiar with. The little unicorn was trying to get a tea bag into the cup, but her hoof was shaking too bad and then her magic faltered, dropping the tea bag to the floor.

“Fiddlesticks,” she swore, pushing her front legs off the counter and climbing down from the stool, having to pick up the tea bag in her teeth.

“You would never have agreed if you knew, would you?” Archer asked softly.

Dinky said nothing at first, climbing back onto the stool and reared up onto the counter, then dropped the tea bag into the empty cup.

“It would be stupid to agree if I did,” Dinky admitted, staring at that cup, her tail twitching incessantly.

“I... I’m sorry,” said Archer from below, “I just wanted to help you. I shouldn’t have... have... not said the truth.”

“You’re right though,” Dinky moaned, her head falling forward, “I can’t even be in the same room with a colt without spooking. Maybe I have a problem.”

“You do have a problem and it’s estrus,” Archer said emphatically.

“Well you have estrus,” Dinky said defensively, climbing down from the stool, then shutting off the stovetop. She turned to Archer saying, “Why weren’t you burning up just being in the room with him? Couldn’t you smell him?”

Archer blushed knowing exactly why she didn’t have a problem between her legs right now. She bit her lip, and faced Dinky saying, “Apple Bloom f-fixed my estrus.” Then she blushed even more, saying, “I know he can do that because... he did... and... he’s really nice and... he won’t lie to you or tease you or anything.”

Dinky gave Archer a long look, noting the blue pony’s lack of a strong scent, the missing stickiness between her legs, her relaxed poise and demeanor, her not being constantly covered in a sheen of sweat anymore.

“You really aren’t in estrus,” she realized in wonder. Then her expression dimmed and she looked aside saying, “I probably made him mad.”

Archer glanced down thoughtfully, “Well, he said he still wanted to help. He told me to talk to you, because I’m your friend, and to bring you back and... get you to drop that tea.”

Dinky giggled, “I did kinda drop it didn’t I.” After a pause, she took a deep breath, firmed her resolve, and looked at Archer saying, “So let’s go back and see if he can help me.” She didn’t look nearly as confident as she sounded though.

When the two returned Apple Bloom uncurled from the floor saying, “Dinky, I’m sorry, are you alright? I didn’t mean to scare you.”

“I-I’m fine,” Dinky said nervously, carefully stepping into her room now aflood with the stallion’s musk rising off of Apple Bloom’s flank. Archer followed her in, and Dinky very deliberately shut the door behind her. Then she turned to Apple Bloom saying, “H-how do we um...”

Apple Bloom sighed, her usual strategy of going straight for the groin seeming a bit fast for this unicorn filly here. She looked about ready to jump out of her skin if Apple Bloom so much as touched her. But hey, maybe Apple Bloom didn’t have to be the one doing the touching...

Apple Bloom puffed up her chest, somewhat more prominent now saying, “First you gotta touch me right here,” laying a hoof across her heart. “I ain’t gonna touch you or move or anything. I just want you to touch me. Here or, wherever you want. I don’t mind it’s okay.”

Dinky’s heart was racing as the colt stilled himself, approaching him carefully looking at him from the side. Was it that easy, she could just... touch him all she wanted? Touch whatever she wanted? Carefully she raised a hoof and laid it against Apple Bloom’s chest, almost startled that she could feel the pony’s heartbeat under there right away. His lemon fur was thick there, and warm.

She looked up at him, but Apple Bloom just smiled and nodded. Encouraged, Dinky brought her other hoof up to brace against him. Sitting on her haunches she felt a little silly swirling her hooves around his thick muscular chest, doing something she never thought she would ever have the nerve to do before. She could get lost in just gazing at that body, and here she was feeling it and sharing in Apple Bloom’s warmth.

Apple Bloom found Dinky’s adoring strokes to be surprisingly calming and more pleasant than she’d anticipated. She sort of wanted to lay on her back and receive belly rubs. She promised herself she’d go back to review that sometime, but Apple Bloom had a job now and that job was studying. Apple Bloom could enjoy herself all she wanted after Dinky’s grades were safe. Pulling away, Apple Bloom presented her side saying, “Okay, now do it to my flank.”

When Apple Bloom pulled away, Dinky found herself reaching after the colt longingly. As his broad side presented itself to her, she nodded at his words and dutifully brought her vaguely manipulatory/ambulatory appendages up to contact his flank. The barrel was round and firm, just slightly plush to the touch. Far down past his heartbeat, but still warm with his body heat. A musky scent was calling her achingly to somewhere underneath him. Her hooves started to stray towards his hind legs inadvertently.

Apple Bloom’s penis meanwhile was quite excited enough to come out from the smell of being in a filly’s room. The physical contact, while relaxing, wasn’t relaxing Apple Bloom’s penis at all. It wasn’t conflicting with that particular kind of excitement, leading Bloom to feel both excited and relaxed at the same time. It was just like that first night of being a boy, trying to sleep in her own room, except here everything smelled like Dinky. Not that Apple Bloom was familiar with Dinky’s smell before this, but she didn’t think now she was ever going to forget it. Smelling it was making her want to do it something fierce. Time to kick this up a notch.

“Okay hold up,” Apple Bloom said, readying herself for full presentation. “I’m gonna lift my leg, and show you my uh... my penis. It’s gonna be okay, and I just want you to know you can... be with it and still be okay.”

“W-wait I mean,” Dinky shifted nervously trying desperately not to wake that ache inside her that wouldn’t go away. “I mean, just a little...” she trailed off into a whimper, then Apple Bloom lifted his leg and... she saw it. Apple Bloom’s limp flesh was already long as her hoof and thick as a broomstick. Apple Bloom’s fur coloring seemed to bleed into it at the base, but around the medial ring it became mottled and then fully pink toward the bulbous tip. Dinky didn’t want to stare at it, but it was spellbinding. To her horror, she felt a tell-tale trickle flowing between her legs.

“Oh no I’m getting wet,” Dinky moaned behind Apple Bloom.

“No, that’s good!” Apple Bloom said, “You wanna get as wet as you can.”

“But‒” Dinky chewed out in a frustrated tone, “That makes me‒ I can’t... think and... hot and sticky and... and how could that help me study?”

“We’re studyin’ after,” Apple Bloom explained, “You’re gettin all excited now, but when we’re done you’ll be more relaxed than you ever been before. You don’t have to worry about studying now. This is just to help you study after.”

Apple Bloom put her leg down facing the unicorn again saying in a practical fashion, “It’s like... it’s like a runnin’ race really. You have to go and pound your hooves like you were pullin’ the earth around under you, and flex your muscles and get all sweaty and excited. You can’t study when you’re runnin’ but after the race you’re all relaxed and happy, and your muscles make the little twinges in it that let you know you did a good job. You follow?”

“So... it won’t help me study,” Dinky said unsteadily, “Buut when I stop it’ll... help me study better?”

“The thing is,” Apple Bloom continued. Even Archer was in rapt fascination, listening to them from up on Dinky’s bed, “Your estrus really really wants you to run this race. It’s like... scratchin’ an itch. You can’t scratch it till the race is done, so are you gonna sit there itchin and try to study, or are you gonna race, scratch it, then study better?”

“That’s just like what Diamond Tiara was saying,” Dinky said veeeery skeptically, as squirming her hindquarters just got them stickier and more humid.

Bloom paused at that, then chuckled, “Yeah, Diamond got me too, but it worked out alright so far. Ah don’t mean orgasm. That’s like uh... aha! Got it.”

Apple Bloom reached over and put a hoof right in the small of Dinky’s back. “Say you got an itch here,” she said, “What are you gonna do?”

Dinky stiffened at the touch, but then said thoughtfully, “Use a back scratcher?”

“W-well I mean,” Apple Bloom said flustered, “You aren’t gonna scratch your belly if your back itches, right? That won’t fix it up there. And you aren’t gonna scratch your leg, or your rump. That’s what orgasm is like. It’s nice, but,” she tapped Dinky carefully on her back again, “It isn’t scratchin’ the right spot. What if you didn’t have a scratcher?”

“I’d um... roll on my back?”

“Ugh...” Apple Bloom facehooved. “A’hm tryin to say you would get another pony to scratch you, which is where I come in.”

She backed up a few steps so that it was easy to point with a hoof right at Dinky’s groin, though the filly was trying to hide it beneath her hooves and tail against the floor. “That itch between your legs there won’t go away no matter how much you roll around, and I don’t think there’s a scratcher for it. You need something besides scratchin’. Somethin’ only another pony can provide. Specifically, a colt!”

“W-what is it?” Dinky asked. Archer nodded frantically, clearly wanting to know as well.

“I uh, I actually don’t really know,” Apple Bloom said embarassedly, “Some sorta balm that my body can produce when I orgasm. I just call it boy goo.” Archer’s eyes lit up with realization of course as she remembered the boy stuff going into her. Dinky was still clueless, but in an adorable sort of way; now that Apple Bloom knew she had the power to make the unicorn feel better it was kind of fun to see her get a little worked up over all this.

“Boy goo, huh?” Dinky said forgetting her embarassment for a moment, and even if her crotch wasn’t tingling and twingeing at the very thought, she’d still be curious simply from the interesting ideas Bloom was bringing up. She tried to imagine a balm down there, like a skin cream or something. It was hard to imagine though, because she was already all wet and slimy down there.

“So anyways,” Apple Bloom continued, “What I mean to say is all that annoyin’ getting sticky and hot and light headed and thinkin’ about dicks, and goo goo eyed and achy and empty and...” As Apple Bloom spoke, she saw both Archer and Dinky’s eyes light up in remembrance, but only Dinky seemed to get more and more into doing exactly what Apple Bloom was talking about. One of them was absorbing the knowledge, the other was getting droopy eyed horny over it. It was kinda funny really, such an easy solution that’s so effective, the two of them like night and day one filled with boy goo and the other needing it. Apple Bloom had to... continue speaking, and not staring in captivation, didn’t she?

“...and all that,” she concluded hastily, “Is to make your estrus stop, by makin’ you chase after colts who then can help you,” She gave them a subtle wink, saying “That’s where the trick comes in. See, Diamond Tiara wanted you to orgasm without boy goo. When you do that, you just go right back to square one. Square zero even. But when you orgasm with boy goo, I mean, I ain’t felt it myself but it looks like flipping a switch. I mean, what’s it like Archer?”

Archer blushed at the attention, but thought for a moment, squirming her legs together experimentally. She said, “It’s like... when you’re the tickliest from feathers all over, you jump all of a sudden into a big vat of warm pudding.”

“Boy pudding then?” Apple Bloom said skeptically.

“It’s more gooey than puddingy” Archer said.

“Boy goo it is.”

“So. Um.” Dinky interrupted tightly, her expression pained, “How do you make this boy goo.”

“Why, with this!” Apple Bloom said, flopping on hindquarters and pointing at her own dick. “Ah just make it unconsciously... by bein’ a boy I guess, and when I orgasm it comes out right nice.”

Dinky was staring at Apple Bloom’s dick again, and it was starting to make Apple Bloom stiffen up down there. She was the only one who could feel her dick twitch in the air sensitively, but together with Dinky she watched it do so. So weird, feeling a boy thing from the inside being all stiff and twitchy. It was different from just watching Rumble’s. Apple Bloom could feel the muscles she had to flex to make it slap up lightly against her belly with a fluttery burst of pleasure. Reminded her that it was hers, and made it hard to think of it as some other colt’s dick, which in turn made it hard to think of herself as a filly not a colt.

“Woah,” Dinky said, “You can... you can move it?”

“Sorta,” Apple Bloom said. “Ah can make it do this,” she clenched down and her dick jerked in the air again. “And also thicken up quite a bit, but that takes um... me gettin horny.”

“Could you make some boy goo?” Dinky whimpered, her piked hooves unconsciously rubbing her aching nethers.

“I ah,” Apple Bloom shifted uneasily, “I gotta orgasm to make it come out, sorry. I wish I could make some for you right now, but it takes a lot of rubbin.”

“Why do I have to orgasm though?” Dinky whined, leaning into her hoof. No doubt despite her complaining, she was well on the way to doing just what she was complaining about. And boy nelly, watching that unicorn fight with herself to stop grinding against her own hoof was more than enough to make Apple Bloom grow fully erect. Dinky couldn’t stop staring at Apple Bloom’s penis, and she couldn’t stop touching herself, so it was like Apple Bloom was making her touch herself, and get all heated and half lidded and breathing heavy. Every moment of that unicorn increasing in beauty and allure as she lost herself to lust was something Apple Bloom could do to her, just by the simple act of erecting where Dinky could see it.

“You uh I‒” Apple Bloom gulped, twitching in that weird way that made her irrevocably stiffer and thicker. “I don’t... know why you uh, have to orgasm, but I do know that the more... excited you are, the better it works. Besides, orgasm feels good. Real good! Only reason not to is, it doesn’t make the estrus go away. Ah can fix that problem. So that means you can orgasm now, and you don’t have to worry about hurtin’ for it!”

“I... I can orgasm...” Dinky said quietly, leaning into her hoof wetly. “It’s okay if I orgasm...” She was starting to make a mess of the floor and Archer went and brought the newspapers she spread out over to where Dinky was. Dinky barely even noticed when Archer shoved the newspapers under her butt. It wasn’t a perfect solution, but it was pretty ingenius of Archer and should work in a pinch.

But Apple Bloom’s appreciation of Archer’s ingenuity was nothing compared to what she felt when Dinky lost herself in the need to orgasm. Apple Bloom stood up shakily, her stiff dick swinging in the cool air as she stared captivated at Dinky’s hips which began a familiar rolling motion, just riding her own hoof instead of a dick. It was like she got more beautiful every second, her poise shifting emphasizing her curves and her soft definition, and those mindless rocking motions just making Apple Bloom’s heart jump in her throat. She had get in that unicorn, one way or another. The more Dinky pleasured herself, the more Apple Bloom wanted to pleasure her.

She stood next to the lonely looking unicorn not sure how to start, or what to do, or how to help, her dick smacking her belly every time it twitched. Dinky’s eyes were closed, so Bloom turned her head to face Dinky’s ear and said quietly so as not to disturb her,

“You can touch it, if you want.”

Dinky’s eyes fluttered open, seeing Apple Bloom’s member fully turgid for the first time. It almost seemed like she didn’t know what she was looking at. But then, her hips started just twitching, and the pitch of her hot breaths rose to a point. Then her eyes widened and she just gave this adorable squeak, and fell over on her side, legs kicking convulsively.

Dinky must have been holding out from orgasm a long time, Apple Bloom figured. Maybe not days but... yeah maybe days. That unicorn was orgasming hard. Even Archer seemed bug eyed at the sight of her friend. Apple Bloom remembered darkly what came next, from when she did it as a filly, and when she tricked Sweetie Belle into doing it. That frightened realization when your loins were begging even more to be stuffed, and it just would not let up. Apple Bloom was not going to let Dinky go through that, not after the nervous wreck that Dinky seemed to be when she got here.

“Git some more papers, Archer,” she said, the blue pony hurriedly complying while Apple Bloom took hold of the heedless orgasming Dinky and unfolded her, laying her out on her back as she went limp from the convulsions within her coming to a rest. It would take a while before Dinky came down from the high though, so Apple Bloom still had time to get started. Winking at Archer, Apple Bloom squatted down over Dinky, straddling Dinky’s legs and holding her dick up in the air.

She said to Dinky whether she heard it or not, “Ah’m gonna do you just like I did Archer.” And with that she let her dick lay against Dinky’s hot soaked folds.

It was like the oasis after the desert. So much touching and cajoling and dancing around it like a bowling ball on eggshells. Apple Bloom wanted to be touched so bad she could taste it. Not on her chest, not on her flank. On her dick. Not anything dry or rough, but only those silky wet petals between the unicorn’s plum colored legs. And she was. Apple Bloom needed to touch Dinky with her dick, and it was okay for her to do it because Dinky needed it too! It made her focus on the rousing Dinky and be more aware of the unicorn’s body, Dinky not just seen but felt, and felt so softly. Just the feel of that soft moist center on the underside of her dick was almost too much for Apple Bloom. She couldn’t wait now.

“O-Okay, here we go,” Apple Bloom said, knowing that if she waited for the unicorn’s answer then Dinky would have already started to suffer from the burning need. So she just answered for Dinky, laying her own tip in those glorious folds Dinky had, and gently tilting Dinky’s pelvis up to an angle she could slide her in smoothly. Dinky’s eyes were still dreamy and relaxed and she had a beatific smile on her face, saying, “That was... so... good...” and right then Apple Bloom found the entrance to her passage. Dinky’s words were cut off and she moaned surprisedly and went limp from the physical sensation and also just from the sheer realization that a boy was nestling his penis in her vulva.

“Dinky, you gotta look!” Archer said urgently. Dinky seemed content to lie there staring at the ceiling, but Archer propped the unicorn’s head up. Once Dinky felt Apple Bloom start to penetrate her, Dinky lifted her head herself, coming to full awareness as she felt something beyond her petals get stretched open by him, seeing her voracious purple abdomen swallow up that penis inch by inch.

“Wh- nguh,” the unicorn spluttered for words, her breath picking up again as the heat flared within her. It was pushed back though, by that incredible dick. The cure for estrus. Apple Bloom was putting it inside her! Was it supposed to go inside her?! “What are you doing?” she huffed, grunting from being stretched tightly around his dick.

“I’m doin... boy stuff,” Apple Bloom said huskily, hiking her hips forward to fully hilt inside Dinky. She was in. She did it. She was as deep in that unicorn as she could go. No way Dinky was going to be scared of her now. Apple Bloom could even feel those funny balls she had lightly resting against Dinky’s pelvis.

Dinky wanted to protest. She didn’t like things she didn’t understand. But she actually did like this? She had to like this, even if she didn’t understand it. Because it felt so good. Why did this feel so good? Why was he putting his penis in there?

Fighting for questions that didn’t have answers, “M-my... orgasm..” she managed to say.

Apple Bloom’s answer was to start pulling out. That made Dinky’s insides clutch needily. She hadn’t even realized just how deep in there he was until he pulled back. She could feel everything. Oh, she could even feel that ringlike shape in the middle as it dragged along the texture of her inner walls! What was inside her? Dinky couldn’t think straight. It was like a cave or a... a place that Apple Bloom’s penis just opened up!

“You orgasmed,” Apple Bloom said tensely, hips pushing pressure on her making his dick slide smoothly in again, “N-now it’s... my turn... and when ah do...”

“Boy goo?” Dinky said giddily, almost reverently, her legs tensing as she felt deeper and deeper that sliding shaft.

“Yeah,” he said lowly, contacting her hips. Celestia did it feel good when he did that. Dinky felt her insides were stretched so wide and her toes were curling from the sensation of that velvety yet stiff shaft pulling everything open down there. Even on the surface something underneath him was scrunching against her labia and and... and all the way inside he was inside he was—!

“Y-you mean... inside?” she said frightened, looking up at Apple Bloom for confirmation.

“Ahm gonna put that boy goo,” he said drunkenly, pulling out of her again without regard to her shuddering gasp, “As deep inside you as I can. When I orgasm I’m just gonna shove it in there an’ cut loose.”

His front hooves left her hips to their own devices, planting themselves to either side of her. Now when he pulled back she could see his whole body just surge above her. Dinky whimpered, her heart thudding in her chest. What had she gotten into?

“Don’t worry Dinky,” Archer said with Dinky’s head in her lap, stroking Dinky’s bangs tenderly, “It feels so good when he does.” Dinky wasn’t consoled at those words though. Not with this happening to her. It felt so good that she wanted to just scream! And boy stuff felt more good?

“How is this possible?” she whispered huskily.

“That’s what I said!” Archer laughed. She leaned over Dinky and, reaching a hoof in between them she lightly tapped the join where Apple Bloom was entering Dinky. “He’s all ready to fix you,” Archer said with a warm loving gaze down into Dinky’s eyes. “Soon as you’re ready.”

Dinky wanted to say she was ready. She wanted to say she was ready to take on three tigers and a dire wolf if it would fix her estrus. If if it would get him to keep doing this. She wanted to tell him how incredible he was making her feel, so much she couldn’t even think clearly with the stretching and sliding sensations coming from her pelvis so much stronger than anything she’d ever felt. And all she could do is stammer saying “I’m... um... I... I don’t... I don’t know...” because any more of this and she thought she would explode!

Archer pulled back and looked forward at Apple Bloom. Apple Bloom’s gentle pistoning paused as he looked down at Dinky’s frightened form worriedly. He seemed so full of power and need, hunched over her hulklike and coiled. He planted his hooves to the floor on either side of her, surging against her as he struggled with his need. “Ah ah ahm sorry Dinky,” he stammered, revealing an anxiety she hadn’t even known he had until she looked into his apprehensive and somehow frightened eyes, “But I just can’t.. I gotta do this I... I can’t hold back any more I just gotta do it.” Dinky’s heart thumped as her insides contracted urgently around him.

And without another word between them, Apple Bloom’s careful slow strokes turned into a rhythmic animal thrusting.

As for Apple Bloom’s perspectivee, she couldn’t believe how conflicted this unicorn was making her feel after she penetrated her. Dinky still didn’t seem ready, and it seemed that the more aroused Dinky got, the harder it was for her to give Apple Bloom any indication or direction. Dinky went from chatty to downright fluttershish which would make Apple Bloom hesitate, since maybe Dinky doesn’t like it after all, but... Apple Bloom couldn’t stop. Even though Archer was there, consoling Dinky and cradling her head and cooing soothing words at her, Apple Bloom could hardly hear it from the intense desire radiating from her loins. The intense desire that surged up in her breast when she saw that unicorn under her, in whom she was buried hip deep, and then Archer went and touched the very place Apple Bloom was going in, pulling back and giving Apple Bloom a bit of a worried look. Not nearly as much as Dinky though.

When Dinky’s frightened eyes had met hers, Apple Bloom just wanted to gently hug this pony and stroke her mane and tell her she’s gonna be okay, but she also just wanted to shove that dick in so it throws that unicorn’s head back and catches her breath in her throat and shows her that she can take a stuffing, that she isn’t made of glass. She honestly wasn’t sure which one Dinky needed, but as her dick continued to slide through that unicorn’s glorious passage, the latter was starting to appeal to Apple Bloom more and more. She just wanted to orgasm so bad! But she didn’t want to scare Dinky. But she‒she didn’t‒she did want to thrust. She had to do it.

“Ah ahm sorry Dinky but I just can’t,” she begged feeling like she was falling off a cliff, bracing her hooves on the floor in preparation to thrust, “I gotta do this,” she tried to explain, the need surging within her as her body got into position.

“I... I can’t hold back any more,” Apple Bloom insisted. “I just gotta do it.”

If Dinky even could say anything, she didn’t do more than whimper and huff and squeeze in there. So Apple Bloom just started thrusting, stroking her dick shamelessly with Dinky’s canal, in that beautiful way that would bring her and, hopefully them both to orgasm. She was desperately rolling into that unicorn, the stuff within Apple Bloom just about boiling up inside her ready to shoot out, yet somehow always just out of reach until that perfect moment. All that Apple Bloom could dribble out was her own sorta girl cum, quickly lost in the ocean of Dinky’s vagina. She wished it was boy stuff instead. She wanted to make boy stuff so bad. She had make herself orgasm, so that it could be boy stuff. Apple Bloom just thrust stronger and stronger, with only the goal in her mind of reaching orgasm, and pumping her stuff into that unicorn hard as she could.

And whattya know, it was the right decision after all. As Apple Bloom’s thrusting met its instinctive rhythm, Dinky’s whimpers slowed and started to turn to heavy breathing and wet gasps. Both she and Dinky began to feel that immense satisfaction of a job well done. Dinky’s eyes half slid closed, gazing up at Apple Bloom in a confused but somehow adoring light. Then Dinky’s hooves unfolded, pressing up against Apple Bloom’s chest for support, and her hips bucked up against Apple Bloom’s inexpertly.

(She’s tryin’ to do it too!) thought Apple Bloom, and she wanted to help the filly do the bucking that Dinky needed to do too. Somehow Apple Bloom managed to bring herself to a halt, pulling her cock half out of the filly and leaving it to drip Dinky’s juices teasingly onto Dinky’s own groin. Sure enough, deprived of the filling made Dinky arch upwards, doing whatever she could as long as it got Apple Bloom back inside her. Once Dinky’s frantic rocking, bucking thrusts had reached a relatively steady rhythm, Apple Bloom started up again, matching it and meeting Dinky’s hips with every upthrust.

That made Dinky react much more vehemently, fighting carnally with Apple Bloom in a way that was more like a beautiful dance of in an out, with no struggle just slamming together and breathing together. Dinky’s eyes opened wide as she said “It... again‒!” And then just as Apple Bloom flared, Dinky’s orgasm closed down on it like a vice. It was frantic and frenetic, and hot as hell. Apple Bloom couldn’t thrust because she was too stuck in there, because Dinky’s legs locked around behind her and that glorious cunny had her so stuck that when she tried to thrust it just carried Dinky’s hips with her. Dinky couldn’t thrust because she was lost in her own world, her eyes rolling back as she convulsed, squelching wetly around Apple Bloom’s cock.

“Lemme... Lemme go I gotta...” Apple Bloom begged almost under her breath, fighting to pull that flared cock out of Dinky’s abdomen, to slide it along her walls somehow. There was just nothing doing. Apple Bloom was stuck on the edge of orgasm and had to sit there with Dinky’s hips locked against hers, while the unicorn squeezed and rippled helplessly around Apple Bloom’s dick, spasming legs kicking out on either side of Apple Bloom, and moaning in an aroused, but... still fearful tone? Dinky looked so scared of what was happening to her...

Apple Bloom’s front hooves just folded down and she held onto Dinky desperately, hugging her close and riding out the unicorn’s needy contractions. It hit her hard that, more than an orgasm, she just wanted Dinky to feel safe and not afraid. That’s why she wanted to make boy goo so much. Buck the orgasm! She wanted to see it happen to Dinky. That beautiful moment when the body against Apple Bloom drains of tension and the filly finally truly learns how amazing boy goo is. That’s what Apple Bloom craved, more than breathing!

At last, Dinky’s hind legs went limp and she loosened up enough that Apple Bloom could pull in and out of her again. Bloom almost backed up to focus on thrusting those important final thrusts, but then she felt Dinky’s forelegs close around her this time, hugging her right back without impeding the motion of her pelvis. Apple Bloom couldn’t even see Dinky’s face, the unicorn still hiding it in Apple Bloom’s chest fur as if desperate to move one single centimeter away from her. It was less effective to thrust this way, but Apple Bloom couldn’t even think about stopping. She should be able to do it like this, if she tried real hard. And she tried real hard.

So while Dinky held on, Apple Bloom just held onto Dinky too and scrunched her eyes shut, concentrating only on the hip movements and the sliding sensation they produced, stoking a rising tingle in her that would make... make the boy goo come out. She didn’t want to make Dinky wait a second longer than necessary. She didn’t want to make herself wait! Apple Bloom wanted to do it so bad. Her cries became gladder, even grateful when that tingle built up in her. When it finally ‘caught’, she just gave a satisfied “Oohmnn,” and hilted inside Dinky, opening her eyes‒ just in time to see Archer, watching it happen to her.

There was something special about another pony just sitting there watching you while you orgasm, while you and another pony were in that crazy position with your dick shoved inside her and her pussy wrapped around you, and it’s just happening to you. Like, like it was more real that way, like you couldn’t trust your own senses because it was just too amazing to feel that dick pumping load after load of boy goo into those fleshy depths. Dinky was shuddering uncontrollably, but wasn’t making a sound, just clutching Apple Bloom like a lifeline. But Archer was sitting there, fascinated look on her face, and that meant this was really happening. Apple Bloom was really a colt, and her boyhood really was inside Dinky and she really was pulsing forth her hot fluid into that unicorn’s vagina.

And most importantly, Apple Bloom really honestly truly wanted to do it. Every spurt, she pumped inside Dinky eagerly and with as much vigor as she could push behind it. It was so earnest a desire, Archer just had to see that on Apple Bloom’s face. There was no joking about what Apple Bloom was doing; it was the most important thing in the world to her, and she wanted Archer to see that in her. Apple Bloom couldn’t just casually say hi, or smile or crack a joke or do anything while she was doing this. She could only sit there cumming her brains out, pumping her boy goo into Dinky, looking at Archer hopefully for validation, because it just felt too good to do anything else.

And Archer gave that validation with a bright, and gentle approving smile.

With the fourth pulse, Dinky tensed under her and Apple Bloom’s excess cum began to flow out of her vagina, pooling on the unicorn’s crotch fur and trickling down her sides and legs to drip heedlessly to the floor. It didn’t matter. Apple Bloom had to keep pumping it even as it spilled out between them. There could have been newspaper there or not, and Apple Bloom honestly did not care. It wasn’t the incredible orgasm that Sweetie Belle gave Apple Bloom, but by golly it was the most exciting one. As her dick throbbed the last few times, emptily, Apple Bloom realized just how hard she was panting, her whole body feeling like it was flushed red.

She started to let Dinky off from under her, but as soon as she did Dinky just hugged her tighter, and continued to hide her face almost protectively in Apple Bloom’s warm chest fur. Apple Bloom rested her weight against Dinky from above, but that... wasn’t going to work. So she just slightly rolled on her side, holding Dinky to her until the two of them were side by side, still hugging close. Matter of fact, Dinky’s insides were still hugging Apple Bloom irregularly along with her hooves, though that “inside hugging” didn’t make Apple Bloom want to thrust any more, not now that her boy goo was out of her body.

Probably for the best really. Apple Bloom wasn’t sure if this Dinky filly could take any more stimulation of her nethers, with how hard it had been hitting her. Apple Bloom stroked her hoof down the back of Dinky’s head tenderly, the unicorn’s blunted horn making Apple Bloom’s chest tingle where it poked against her while the unicorn buried her face in Apple Bloom’s chest. Dinky was just the picture of adorableness. Apple Bloom felt like she could gaze at that unicorn for hours, whether her dick was in her or not.

Archer came over and sat down beside Dinky, reaching out a hoof and looking at Apple Bloom uncertainly, saying “Um... can I...”

“Sure,” said Apple Bloom, opening her hooves and letting her sandwich Dinky between the two of them, in a much less frantic and more gentle hug than Dinky had had over the past ten minutes or so. Not long after, Apple Bloom’s penis softened up enough where it wouldn’t stay in Dinky anymore, slipping out wetly to dangle between them. Dinky actually gave a quiet, distressed noise at that, her hips moving around briefly before stilling again. Archer looked at Apple Bloom questioningly, who just whispered very quietly (not that it’d be possible for Dinky not to hear) “I think she really likes my penis.”

The very, very female ‘she’ didn’t dispute those words, not one little bit.

Dinky eventually shifted and turned her head to rub her cheek sideways against Apple Bloom’s chest, giving a soft “Mmmm..” and opening her striking golden eyes with a mystified smile.

“How did you... find out about this?” Dinky said at last when she had the words to say again.

“Trial and error, believe it or not,” Apple Bloom answered honestly.

“Really?” Archer said quietly but curiously, still in their three layered embrace.

“Well, ah was just y’know checking this penis out since ah just got it, and Scootaloo found me then. She showed me her estrus to show how bad it was and we just kept feeling like masturbating the closer we got to each other.”

She patted Dinky on the shoulder, who was leaning sideways against Apple Bloom with a contented smile. “Like you saw with Dinky she just had to masturbate, right? So Scoots was rubbin’ on anything to get herself going, and the closest thing was mah penis. Like it was a pole or something. And ah was rubbing back because it made me want to masturbate too, which works like rubbin’ mah penis. We were like, huggin together and rubbin on each other, then I just accidentally slipped in.”

“You accidentally slipped in?” Dinky said astonishedly.

Apple Bloom blushed, turning her head aside a bit saying bashfully, “It wasn’t no problem, since we were already rubbing together. But you gals remember what a penis feels like in you, so soon as Scootaloo felt that she pushed me all the way in.”

“Then you did the boy goo thing?” Archer suggested. Apple Bloom shook her head.

“No,” she said, “We were a bit confused at that point. But soon as we tried to separate we found it’s the sliding that feels good. So Scootaloo was ridin’ me like a scooter, slidin’ me in and out and then she went and orgasmed.”

Both girls ooohed at that.

“I just had to keep sliding mah penis like that, so when she stopped to orgasm I just sort of climbed on top of her and started pushing into her mahself. So it worked like I was doin’ with you two, all on top of you and pushin’ it in. Sweetie showed me another way but, that’s how it went mah first time.”

“You had to?” Archer asked testily.

Apple Bloom nodded, “Yeah it... you girls don’t even know how good you feel in there. Ah can’t even describe it, besides the obvious hot wet and squeezin. It’s like that scratchin’ your back or, no, like how a filly wants to go rubbin’ against a stallion. You know, you can’t even think about anything else, and you don’t even realize what you’re doin’ until the teacher yells at you. That’s sorta how it feels, except for me it’s your insides not a stallion, and it’s not mah whole body just mah penis that needs rubbin’”

“So it’s like you have a little filly coming out of your hips,” Archer mused, “And our insides are like big hunky stallions to her.”

Apple Bloom pfft, couldn’t help but snicker. “That’s surprisingly apt,” she said laughingly to Archer, “But... but it sounds so weird when you say it!”

Bloom paused in thought and added, “Thankfully the boy goo just comes out by itself when I orgasm in a filly, otherwise me and Scootaloo would have been stuck doin that forever.”

“Does it come out when you orgasm outside?” Dinky put in. She didn’t seem offended to be hugged between the two of them. Not that it was possible to be offended considering how happy her loins were. But Archer was nuzzling close to Dinky as tenderly as Apple Bloom could imagine. Apple Bloom was honestly touched by Archer’s affection. Study partner my tail, this was something special.

“I haven’t tried yet,” Apple Bloom admitted. “I don’t want to waste it or nothing. I been focusing on helping fillies, not experamentin so much.”

“You want to try it now?” Dinky asked.

Apple Bloom smiled apologetically at that, saying, “Do you mind if we extricate ourselves for a minute? I wanna show you something.”

Dinky smiled that beautiful smile, saying “No it’s fine. I feel calmer already!”

Dinky found that they separated with more difficulty than expected. Specifically in the groin area. “Ewww,” she said, lifting a leg to look at her crotch. It was a royal mess, for sure.

“Yeah and,” Apple Bloom pointed to the puddle of boy goo that had overflowed and trickled out and landed on the newspaper.

“Woah,” Dinky said. “That’s... that’s really boy goo?”

“And all of it went into your vagina,” Apple Bloom said teasingly. Dinky stood up and twisted around, looking at her own vagina. In the mirror that is. Ponies can’t actually look at their own vagina. Except Blossomforth.

“Well it just looks like a mess,” Dinky said somewhat unhappily, then gave a surprised, “Oh!” as a blob of cum emerged from her vagina, trickling down to the floor.

“Yeah, it kinda drips outta you for a while,” Apple Bloom said blushing. “Best to stay on the newsprint until you’re all clear.” Dinky pulled some newsprint over, but seemed equally fascinated about watching her vagina drip with every little aftershock in there.

“Why do you make so much?” Dinky asked curiously.

“I don’t know,” Apple Bloom said, “It just seems weird to me– woah, Archer!”

The pony in question had crouched down over the puddle Apple Bloom and Dinky left behind and was rubbing her groin against it.

“What?” Archer said, with a devil-may-care laugh, “It feels kinda good.”

“You don’t need any more do ya?” Apple Bloom asked uncertainly.

Archer frowned at that saying, “Well I don’t know. I don’t think so, but just to be sure...” She laid down on her belly and just started rubbing it into her labia with a hoof, a look of satisfaction on her face as she did so.

“Fascinating,” Dinky said with a smile, “I wonder how many times you could reuse it?”

“Won’t do much good without a penis to deliver it, if you have to get it all the way in that is,” mused Apple Bloom.

“All the way in,” Dinky repeated, her insides purring at her happily.

“So anyway,” Apple Bloom recalled, “You’re seein’ every drop of boy goo ah can make. Ain’t got none left in mah hips. Ah can’t stop until it all comes out, and so now I gotta wait until I make more.”

“So when you were um... overflowing me, you couldn’t stop and put it in another filly?” Dinky said speculatively.

Apple Bloom shook her head, “Nope, even when it goes over ah can’t even move, just gotta sit there pumping it into you. It’s like when you’re clenchin’ around me in your orgasm, except for boys it’s a ...pumping action.”

“That’s kind of cool,” Archer said in a heady excited voice flushing in her face. “So we know if you start pumping it in, that you’re going to keep doing it even if you try not to. We can enjoy since it’s a sure thing we’ll get all of it once it starts!”

Apple Bloom blushed too a bit more self consciously saying, “That seems about the sum of it. Ah ain’t exactly tried not to though. Why would I? Ah love givin’ you boy stuff. That goo makes you feel all better, and you look amazing when you do.”

Dinky’s hindquarters stopped the happy wiggle, and she suggested, “Maybe you could try to stop halfway through, then put the rest in a second filly?”

“Well ah don’t think‒” Apple Bloom stopped and nosed her hoof in thought, “You know, I actually hain’t never tried that before. It’d definitely let me get more fillies in one go.”

“Just something to think about I guess,” Dinky said, “I’m very content with you doing all of it in just me. I was just... surprised when I couldn’t hold it all in.”

Apple Bloom nodded then turned to Archer saying, “Hey, you done yet? We gotta clean up. We got some studying to do!”

Dinky visibly brightened at that, saying “Oh that’s right... so you mean I can... I feel, I mean, I can think so clearly again!”

“That’s the plan,” Apple Bloom said. “Still think you got no chance to pass your exams now?”

Dinky gave a thin lipped smile saying, “...let’s get cleaned up so we can study.”

Archer waved a hoof at Apple Bloom saying “Yeah I’m just, messing around.” She picked up a particularly messy newspaper in her hoof and her mouth and carried it over to a trash bag that she obviously had ready for that sort of purpose.

“How do I clean this off?” Dinky asked, looking at her increasingly sticky groin.

“Orange mess works best,” Apple Bloom said, “But that’s mostly for floors. I’d tell you to take a shower but that might clean out your insides too, and you don’t want that.”

“I’ll just try a damp cloth,” Dinky said, carefully hobbling over to the upstairs bathroom. Apple Bloom followed her in there after a thought, and Dinky was most grateful to have some help wiping herself down there. While she did, Archer took to Apple Bloom’s groin with a washcloth, but seemed more intent on just feeling out what Apple Bloom had down there than actually cleaning it. Apple Bloom did her best to get Dinky all smooth and clean, wiping across the entrance with utmost care so as to keep the unicorn nice and full of her boy stuff. When Dinky moaned at the sensation, Apple Bloom backed off, blushing as she realized she might have been making Dinky excited again.

“You alright, Dinky?” she asked testily. “Your heat’s still gone, right?”

Dinky nodded, “It’s just so sensitive down there, even still. It never stopped feeling good, just stopped... feeling bad.”

Apple Bloom rinsed off and wrang out the washcloth, swiping across Dinky’s groin one more time. Archer was just laying on her back with the washcloth she used on Apple Bloom laid over her face, breathing in deeply and going “Boy stuff is so ...awesome.”

“Sure is,” Apple Bloom agreed thoughtfully. “Girl stuff is awesome in its own right though, if you know the trick.”

“We know the trick,” Archer said smugly.

“But what we need to know,” Dinky countered, “Is even one single word of what Mister Tinker or Miss Cheerilee said this past week. So let’s get studying!”
