Apple Bloom's potions have been causing strange side effects. Applejack insists on observing her sister's lessons with Twilight and testing the results. Unfortunately, Applejack isn't prepared for the side effects of Apple Bloom's latest potion.

After losing a whole night's sleep dealing with the aftermath of one of Apple Bloom's potion-making experiments, Applejack decides to supervise her little sister's work. Apple Bloom's next potion causes some unfortunate side effects, however, and Applejack finds herself needing some very intimate help from Twilight to counteract this new potion's effects.

Chapter 1

"I ain't gonna get a lick of sleep tonight," I muttered to myself as I tried—for the third time—to tuck Apple Bloom into bed.

"Sorry, Applejack. I don't know wh—" Apple Bloom's voice cut off as she yawned. "I keep tryin' to go to sleep, but—" Her hooves spasmed under the covers. At least it was a small spasm this time. "—the twitchin' just won't stop."

"It's okay, Sugarcube." I brushed my hoof through her mane and smiled. "But maybe you oughtta take a break from makin' potions with Twilight for a while. This ain't the first time your concoctions ended up havin' some mighty strange side effects."

Apple Bloom sat bolt-upright in the bed. "Take a break? But Twilight Time is the most fun I get to have all week! Applejack, you can't ask me to stop goin'!"

I sighed. "Fine, fine, Sugarcube. I know you like workin' with potions. Just be careful, all right?" I pressed her back into the bed gently. "An' please, Little Sis, try to get some sleep this time."

Apple Bloom started to respond, but another yawn drowned her words. She breathed out heavily and snuggled down into her bed, her hooves giving one last twitch.

Right then and there, I decided on a plan of action. Twilight was my friend, and the most trustworthy pony I knew—but sometimes a big sister had to look out for her little sister. Anyway, Twilight was the head-turning-est pony I knew, too, and this plan of action meant getting to spend more time letting her turn my own head.

I smiled as I closed Apple Bloom's door. I felt a nice, warm tingling coming from my hindquarters. 'Tweren't much time left to sleep tonight, but there was time enough for a little fun before I had to tackle the day's chores. I headed back to my room.

Saturday afternoon found me in the library of Twilight's new Friendship Castle, or whatever we were supposed to call it. I didn't usually like to spend a lot of time there—too big and empty, not nearly homey enough—but today I had my reasons.

"Still ain't what I'm lookin' for, Twi," I said, closing another book and adding it to the pile beside me. "Sorry to make you go through all this trouble for nothin'."

Twilight rubbed the base of her horn with one hoof, grimacing. "Are you sure? I would have sworn Peabody had written a chapter or two about horticultural applications of unicorn magic during astral conjunctions."

"He... uh..." I gave the book a sidelong glance and prodded at it with one hoof. "Yeah, well, maybe so. But it still ain't what I'm lookin' for." 'Course, what I was lookin' for had no more to do with books than a sheep-dog in a shearing shed. I might've let Twilight think it did, but I was never properly dishonest about it.

I was spared from my rumbling conscience a moment later, when the drum of tiny hooves told me that my sister and her friends had arrived for their weekly lessons.

Apple Bloom clopped into the library at the head of her little herd. "Hi, Twilight! What d'ya have for us to do tod—" She cut off when she saw me.

"Hey there, Sugarcube." I gave her my best warm, sisterly smile.

Sweetie Belle and Scootaloo filed into the library and ran to Twilight, but Apple Bloom stood as still as a statue, staring at me. "Applejack, what're you doin' here?"

"Oh, nothin' much. I just thought I'd come see what this potion makin' business is all about."

Apple Bloom frowned. "I know you mean well an' all, Applejack, but don't you think Twilight's responsible enough to look after me for a couple hours?"

I chuckled. "Of course I think Twilight's responsible, Sugarcube. She's maybe the most responsible pony I know. But that don't mean I can't worry about my little sister a bit, if I want to."

Apple Bloom's lips tightened, and she paused for a moment. "You're not gonna try to stop me makin' potions with Twilight, though, right?"

"Nope," I said. "Big sister promise. I won't interfere with your potion-making. I'm just here to observe." I made a cross over my chest with one hoof.

With a sharp nod, Apple Bloom turned away and trotted over to Twilight, joining her friends.

The next hour was... well, it was about as boring as a rutabaga at a rodeo, to be honest. Just a lot of watching three little fillies make a mess of a perfectly good library. I didn't envy Spike the clean-up job he was going to have later that evening. From time to time, Twilight would give one of the fillies a little lecture about something or other. Never anything very interesting—not the sort of lecture that'd help you grow better apples, or sell more fritters—but Twilight ain't hard on the eyes, and I gotta admit I didn't mind a whole lot, watching her flank bob up and down as she paced the room, overseeing the girls.

By the end, Sweetie had managed to sweep up a good quarter of the mess she'd made trying to magic her broom around in the first place. Scootaloo had built herself what seemed to be a perfectly functional unicycle, even if she did have about a dozen parts left over that she didn't know what to do with. And Apple Bloom—my sweet, innocent little sister—had brewed up a brand new potion, all purple and bubbly and not-at-all pleasant looking. I gulped and trotted over to join her and Twilight.

"—not really sure," Apple Bloom was saying. "I think I got everything right, but the book you gave me said it should've turned out yellow."

"Well, there's always some natural variability in how potions turn out," Twilight said. "It's probably nothing. Though I've never seen a concentration potion with that color before."

"So you think it's okay to drink?" Apple Bloom asked.

I butted in, like I'd been planning to do anyway. "I think maybe I should try this one, Little Sis."

Apple Bloom frowned up at me. "I thought you said you weren't gonna interfere with me learnin' about potions, Applejack."

"An' I didn't. I let you make the thing all by your lonesome, didn't I? But after last week, I think maybe you oughtta let me try 'em out before you do. Just to make sure everything's safe. Whatever the effects are, they should be less for me, right? I'm older and bigger'n you."

"But I made this for me!" Apple Bloom protested. "It's supposed to help me with my school work. What do you need a concentration potion for?"

I could think of a few things, actually. I took another quick glance at Twilight's flank before snapping my head back to my sister. I'd been thinking about that flank a bit more than I'd like lately. It'd be nice if I could focus on tending the apple trees all day. Those noontime breaks, alone in the barn, weren't helping get the harvest in.

"Never you mind, Sugarcube. An' I promise I won't drink the whole thing—just enough to be sure it don't have any unwanted side effects, like that twitching you got last time. After that, it's all yours."

"Twitching?" Twilight asked. "Did something go wrong with the potion you made last week, Apple Bloom?"

Apple Bloom turned her attention to the floor of the library. "Yeah, maybe a little..."

"And you didn't tell me about this before?" Twilgiht's eyes narrowed. "Apple Bloom, I thought we'd discussed this before. Potion-making can be dangerous. If your potions are having unintended side effects, I need to know about them."

"I know," Apple Bloom said sheepishly. "But it wasn't all that bad. Just kept me up through the night. I was fine by Sunday."

"Still, it ain't right you riskin' your health like that, Sugarcube." I walked over to the still-bubbling potion and scooped it up with one hoof. "I know you wanna do this by yourself, but I'm your big sister, and sometimes I gotta look out for you, whether you want it or not." I took a long sip from the potion.

Twilight raised a hoof at me. "Applejack, wai—" Her lips tightened as the potion went down my throat. "Sometimes I wish you two would stop and listen to me. You probably shouldn't have drunk that just yet. If Apple Bloom's potions are having side effects, we should spend some more time trying to figure out how that purple color came about."

I set the potion back on the ground and rolled my neck. "Nah, it's fine Twilight. Us earth ponies are hardy. Even if there's a little somethin' wrong with this, I'm sure I can handle it. Better me than my little sis."

Apple Bloom eyed me warily. "So? How do you feel, Applejack? Can I try it now?"

"Gimme a bit, Sugarcube. I don't know if it's workin' at all yet. I'll let you know when I do."

Apple Bloom frowned and settled her rump on the ground, watching me patiently. I took a long look around the room, trying to figure out if I felt any different. I couldn't say I did. I focused on one of the bookshelves nearby, reading the titles at a distance. They weren't any easier to read than usual. And I didn't seem to have an easier time focusing my attention on them, either.

I turned to Twilight. "I dunno, I think maybe this one was just a dud. Does that hap—"

I cut off, feeling my heart start to race. Somewhere back by my tail, my body suddenly started to feel very, very warm.

"Yes, though it's rare," Twilight said, not noticing my discomfort. "If the ingredients aren't fresh, that can dull the effect. Apple Bloom, tell me what ingredients the potion called for."

Apple Bloom scanned the book in front of her. "Jasmine, orris root, strawberry leaves, violet petals, an' yarrow."

"All fresh. I know I keep each of those five handy; they're common ingredients. And I don't think I've run out of any of—" She paused, humming to herself. "Wait, didn't I use... Yes... And I told Spike..." Twilight took a glance around the library. "Where did you get the violet petals, Apple Bloom?"

"Yeah, those were kinda tricky to find. They were way up on one of the high shelves. I had to get Scootaloo's help to reach 'em, 'cause you were busy helping Sweetie Belle with her levitation."

Twilight stepped closer to the remains of the potion, staring like she expected it to unbrew itself and reveal its ingredients. Then her eyes drifted up to me, and she must've seen how much my tail was twitching, or maybe how I was starting to sweat. Her face went a little pale, and she took a step backward.

"Oh. Oh, yes. I... I think I may know what caused the purple color. I should have realized—" She started pacing, which didn't help me none, because it meant I had a very clear view of that flank I'd spent the last week thinking about. And—because this here concentration potion was, by now, certainly helping my concentration about some things—I got a nice view of what her tail usually hides, too. I had to bite back a moan.

"So it's a dud?" Apple Bloom asked.

Twilight shot another glance at me. "Well, not exactly..."

I felt my hindquarters bump up against one of the library's bookshelves. And I felt them hindquarters—very gently—start grinding against the corner of that bookshelf. Oh Celestia, it felt good, like I'd got an itch deep inside me that I had to scratch or I'd just go plum crazy.

"So can I try it?" Apple Bloom asked excitedly.

"No!" Both Twilight and I said on top of each other.

"Aww, c'mon!"

Twilight gave me another nervous glance, and I tried to keep myself from grinding back against the bookcase. "It's just... we still don't really know what it might do. I think the violet petals you used might have... gone off a little. And I think it's best if only Applejack drinks that potion. Just to make sure it's okay. Anyway, it wouldn't have done what you wanted it to do, Apple Bloom."

My sister gave Twilight that suspicious stare I know all too well. "Yeah, but how can you be sure it don't wo—"

"I think," Twilight said imperiously, "that we're going to have to call an end to Twilight Time for this week, girls. I'll see you all next week, and we can pick up where we left off."

I sighed, but I tried to be quiet. Yes, please, anything to get those three fillies out of the library, so I could... So I could... I took another quick glance at Twilight, and images started flashing through my head faster than I could make sense of them. I turned away before they overwhelmed me, but already I felt that warm glow in my nethers starting to build again. I pressed back against the bookcase harder.

"That's not fair!" Apple Bloom said. "We was just talkin'! You can't just say we're done. I wanna know what went wrong with my potion."

I grimaced. "Sugarcube, your big sister is tellin' you to go home right now. We can talk about this more later."

"You're gonna make me stop learnin' about potions, aren't you?"

My knees started to tremble. That itch was getting worse, and the bookcase wasn't helping much anymore. "No. No, Sugarcube, I'm not gonna make you stop. But... But Twilight an' I need to have a talk, mare to mare, okay? Now will you please do what I say an' go home?"

Apple Bloom kicked her hoof against the floor and turned. "Fine, whatever. I guess I'll talk to you later. C'mon, girls. We ain't gonna stay where we ain't wanted."

The three fillies fell in together and clopped out of the library, muttering to each other. Twilight used her magic to close the door behind them after they left.

"Uhh... So... Do you know what went wrong with the potion, then, Twilight?" I asked, grinding against the bookcase hard enough to make it creak. There weren't no holding back now, really.

Twilight blushed. "I ran out of violet petals last week. I'm pretty sure Apple Bloom used the Heart's Desire instead."

"The... You mean, this is some kinda love potion?"

"Well... Maybe?" Twilight turned her head away. "I'm not sure. It's not a proper potion, just a mistake. If I had to take a guess, though, I think it's probably more of a lust potion. And I'm guessing you must've imprinted on me?"

I grunted, and the bookcase creaked again.

"Sorry, Applejack. I didn't mean to... I mean... I'm sure this must be really uncomfortable for you. Especially wanting another mare like that. If there's anything I can do to help... I mean, well, obviously I could... But that's not right... I mean, you're under the influence of some crazy potion, it's not like you actually think that way about me. It'd be wrong to take advantage of you like that. I mean, I'm sure it seems like you want that sort of thing now, but when the potion wears off I'm sure you'll feel a lot better if we don't—"

"What the heck are you talkin' about, Twilight?" My tail started to twitch something fierce.

"I just don't want you to... make a mistake? You know?" Twilight started pacing again, faster now, making little circles between the bookshelves. She gave a nervous laugh. "I mean, it's not like we're attracted to each other, right? So you'd feel really bad if the potion made you—"

"Uh, well... About that, Twi... Actually I am kind of attracted to..." My voice trailed off as I started staring at that beautiful lavender flank again.

"Y–you are?" Twilight blushed. "Oh. Um. I didn't realize that you... I mean, if I'd known before, maybe... But... Oh, ponyfeathers." And then in one quick motion, Twilight scooped up the rest of the potion and poured it down her gullet.

I just stared at her for a minute. "Twi, you know what you just drank, right?"

Twilight's cheeks burned bright red. "Mmm. Yeah, I think so."

It felt like bees were buzzing all through my nethers. Wet bees. Bees who were very angry about being wet. For a moment, my imagination took over and my jaw went slack.

"Um, Applejack? Are you okay?"

I realized I was grinding against the bookcase again. And groaning, loudly. I tried to settle myself. "No, Twilight. No I ain't."

Twilight's horn glowed for a moment, and she levitated a large, round cushion from the far end of the library. "You know, there's an easy way for us to deal with this," she said, setting the cushion down and going to lie on it. Her hoof began to stroke against her own nethers.

Now I gotta say, at this point I wasn't rightly sure what to do. I mean, obviously Twi was giving me every indication that she wanted to... toss a little hay, as we liked to say on the farm. But I ain't the type of pony to toss a little hay with some mare I ain't never even kissed. On the other hoof, them bees were still pretty angry, and I'd already started to leave some unfortunate stains on the edge of Twilight's bookcase. This was a dilemma of the first order, the kind my ma used to warn me about before she passed on. I moaned uncomfortably, still rubbing against the bookcase.

Twilight's tail was twitching like a rattlesnake caught in a cleft stick. "Oh, for pony's sake, Applejack! Will you please come over here and fuck me, already?"

Well, that got my attention. I fought my hips to a halt and took one awful step away from the bookcase. Them bees started stinging something fierce, without the sharp edge of wood to calm them down. "I didn't... Hahhh... I didn't think you were that kind of pony, Twilight." Slowly, agonizingly, my hooves took me to her cushion.

"I'm not," she said, her cheeks turning crimson again. "But... but you're beautiful, AJ, and I'm tired of using my hoof when I think about you, and—" Her voice cut off abruptly.

"You too?" I muttered. "Well, why didn't you say nothin'?" I stepped onto the cushion, straddling her.

"It doesn't matter. Please, just... Oh Celestia, it hurts, Applejack."

I leaned down and kissed her. There. Now nopony could say I did anything with a mare I hadn't kissed before, at least. She kissed me back, hard. Her tongue traced my lower lip. She bucked her hips up, pressing her nethers into my hindleg and rubbing herself against it. I could feel a trickle of something wet on my fetlock. My imagination took hold again, and in my mind I could see what she was doing. The bees buzzed like a swarm of angry... Oh heck, I couldn't even make countryisms in this state.

Twilight groaned against my lips. "Oh please, please, please. Just like that."

I gave a grunt of my own. "I ain't doin' anything, Sugarcube. That's all you." I tried to move my hips around to find some way to get her hoof on my own nethers or... or something. It was hard to think, with the way them bees were buzzing. I just couldn't find anything to rub against, though. Twilight's legs weren't giving me any help.

Twilight moaned again, and I gave her one more kiss before pulling back. "This ain't gonna work, Sugarcube. I need some help of my own, or I'm gonna... I'm... I don't rightly know what I'm gonna do, but I don't think it'll be pretty."

With a regretful whimper Twilight nodded. "Okay, why don't we try... Can you turn around, AJ? I've... read a couple books, and I think maybe we can..."

"We can do what, Sugarcube?"

"Just... yeah, turn around, like that." Twilight squirmed around underneath me as she spoke. "Okay. Now lie down right there."

For a pony with this sort of hankering, Twilight seemd awfully embarrassed, but I did what she asked. Her directions left her facing my nethers and me facing hers, and I could see that they looked uncomfortably swollen. My own probably looked the same. For a moment, I found myself thinking about Winona when she'd get in heat. Ponies didn't get in heat the same way dogs and farm critters did, but I had plenty of experience with what happened to other animals, and—

I felt something rough and wet brush against my nethers, shoving inside me just a little. I gasped. I damn near shouted. Oh Celestia, that felt good. The bees stopped stinging and started making some sweet, delicious honey, the kind that made me feel all warm and gooey inside.

"What in tarnation was that you just did?"

Instead of answering me, Twilight did it again—and then I felt a little suction, a little pop, right around my most sensitive bits, the parts my hoof always sought out when I let myself think about... My eyes rolled back and I gave a quiet whinny. That felt so good. So, so good.

It dawned on me that I was staring right at that flank I'd spent so much time thinking about. More than Twilight's beautiful lavender flank, I was staring right at her most private parts—parts she'd made very clear she wanted me to touch. And I was getting all the enjoyment I could want, without having to lift a hoof for my own pleasure. My life could not, I realized, get any better than this.

I felt that rough, wet patch brush against my nethers again, and I finally figured out what Twilight was doing. She was starting to tremble under me, her tail twitching like a thing possessed, so I leaned in and tried it myself. I licked across the warm, pink skin of her own nethers. They had a taste to them, and somehow it reminded me of apples. Twilight shuddered violently and I could feel her breath against my own skin.

I licked again, eager for more. She couldn't really taste like apples, could she? But she did, she really did. I think I fell in love with her a little, right then and there. I mean, she'd always been a beautiful mare, and that was hard to ignore. But her nethers tasted like home, and there was just something so right about that.

Suddenly, I felt something parting my nethers and pressing deep inside me. I sucked in a breath, shivering. Twilight wouldn't... that could be dangerous, using her horn like... But no, this didn't feel like no horn. It wasn't hard like that, and it certainly didn't feel sharp. It began to move back and forth inside me. I'd never felt anything like it before. I gave another lick to Twilight's nethers and then I spoke. "Sugarcube, d'you mind if I ask what you're doin' back there?"

"Don't you like it?"

I gasped again, my whole body shaking. "No, it's... it's real nice, Twilight. I'm just curious, is all."

"Would you mind, um... could you kiss me a little more... down there? While I tell you, I mean. It's... it's starting to hurt again."

"Sure thing, Sugarcube," I said. I bent my head down again and pressed my lips to her nethers, breathing against them and licking slowly.

"Ohh. Oohhhhh... Oh please, AJ, that feels so good. Could you go a little faster?" She moaned again. "Yeah, like that. Oh Celestia, that's perfect. And I'm just... It's a magic spell, that's all. I, um, figured it out about a year ago. It's just a big telekinetic tube that pushes outward, sort of like water pressure. Telekinetic energy functions like a non-compressible fluid, you see, and—"

I didn't hear the rest. I was too busy enjoying the sensation of having Twilight's magic tube sliding into and out of me. It was wonderful. Didn't even feel like bees were attacking my nethers anymore, more like somepony'd found a way to distill pure happiness, and then pumped it inside of me until I felt just about ready to burst. My eyes rolled back again, and I felt my hips beginning to sway in time with Twilight's magic.

For a moment, the world seemed to go black around me, and I think I might've screamed a little. I buried my muzzle against Twilight's privates, which she didn't seem to mind none, and started gasping for air. Waves of happiness rolled through my body—over, and over, and over again, and only gradually did they start to subside. I could tell I wasn't doing a very good job licking anymore, and I felt a mite bad about that, but it was so hard to concentrate with what Twilight was doing to me.

After I got my breath back, I had a thought. "Hey Twilight," I asked, "D'you ever use this tube thingamajig on yourself?"

She squeaked at the question, which made me chuckle. Here we were, doing something I never thought I'd do until I was a properly married pony, and she was still shy about talking it through? Only Twilight. "Yeah, sometimes," she said eventually. "It's... it's probably my favorite way to... um... make myself feel good?"

I nodded, stroking a hoof lazily across her nethers. "D'you think it'd be long enough to maybe fit inside two ponies?"

Twilight was silent for a moment. "I don't know what you're... Oh, you mean like... Hmm. Yeah, I suppose I could extend the length, but what are you thinking we—"

I got to my hooves and turned back around , laying down square on top of her and planting my lips against her own. "I'm thinkin' I like kissin' you, Sugarcube. And this'd be a whole lot easier if I could kiss you while we're... What do you call it, when it's two mares doin' it? I suppose with that tube of yours, maybe this is just some right proper fucking."

"I still don't think I understand," she said.

"It's easy, Sugarcube." I ground my nethers down against hers. It helped a little, but the bees were starting to buzz again. "You just magic on up that tube of yours again, except this time you put one end inside me, and you put the other end inside yourself, and then we... I dunno, we just keep doin' what we've been doin', I guess."

"Oh, well, that's not too hard." I felt the tube inside me pop, like a water balloon, and I moaned involuntarily. Then a new tube took its place—the same as the last one, for all I could tell. Except it started moving, and at the same time I could feel Twilight's nethers grinding against mine. The feeling was... I don't know if I've got a word for it. Rarity'd probably call it 'exquisite' or something like that. I guess I'll just say it was pretty amazing. As good as it was having Twilight lick me, as good as her magic tube turned out, this was better. A lot better. Feeling her soft little body grind against mine, feeling how that moved the telekinesis tube she'd put inside me, and being able to stare into her eyes and kiss her while it all happened. Well, that was something special.

Twilight shivered under me, so hard I almost got worried about her. She started to whimper, and her hips moved faster and faster, which just made everything feel that much better for me. Her breath against my lips was hot and ragged, and she groaned like she was worn down from a hard day of apple-bucking. It was pure magic to watch. Made me want to do this more often, potion or no potion. Then her voice turned into a high-pitched whine, and she squeaked over and over again. It was kinda funny, honestly. Sweet too, though. And I wasn't in any position to be laughing myself, 'cause she was grinding against me so hard I could barely even keep my eyes focused. It weren't long before my body was shuddering itself apart again, too, and I started making some pretty embarrassing noises of my own. But heck, what's a little embarrassment between friends, especially if it means feeling like I felt just then.

I don't rightly remember what happened after that. It went on for a while longer, and maybe we found some new ways to arrange ourselves and our nethers. It sure felt good, though—that's all I really remember. Celestia, but it felt good. Even remembering it makes me feel all wet and gooey inside. But there's not really a lot more to say. Twilight and I fucked each other silly. We fucked until our knees got so weak that neither of us could walk straight. And it was amazing, and I want to do it again. Next week, and the week after, and every week for as long as I can think ahead.

But the best thing about it, the absolute best, is that next time I won't have to come up with another wild story to explain to Apple Bloom why she wasn't allowed to try any of that potion she made. I really do hate it when I can't be honest with my own sister.
