>You are a unicorn mare, generally shy and soft spoken, you also wear exclusively long but plain and modest dresses. While these two facts might seem initially unrelated, they both stem from the same issue.

>You are a futanari, a mare that also has the reproductive organs of stallion, and, well, to put it bluntly, you're male parts are very large. You mostly keep to yourself, however today, you must go out and do some shopping.

>You put on your favorite dress, grab your bit purse and head for your door.

>You walk towards the market not far from your house, checking over your shopping list, the first item, "Apples."

>You arrive at the market and notice the line at the stall selling apples and consider skipping it for now, though the market had just opened and was fairly busy. Deciding it wasn't too bad, you got in line for apples.

>"This is a pretty big line isn't it?" you hear a voice behind you. "Market wasn't nearly this busy in the town I used to live in…" You turn around and see a pegasus mare, realizing she's trying to start a conversion with you.

>You blush lightly as the mare looks at you before pointing a hoof at your mouth, "Non… parlevous … um… Prancois?"

>The mare looks at you, raising an eyebrow and cocking her head to the side "You… don't speak Prench?…"

>You blush heavily, and point at a random object over the mare's shoulder. She turns to look "huh?"

>As she's momentarily distracted you takes the opportunity to run away from this social situation, careful not to trip over your dress. "The carrot stand?" You hear her say as you bolt , "Wait, where did you go?"

>In your dash to escape contact with another pony you were paying more attention to where you were leaving than where you were going, and you find yourself colliding with the beautiful unicorn mare that owns the boutique you order your dresses from. Normally you just send in orders and payment by mail and have the dress delivered to your house, so you've never really talked to the seamstress.

>You both fall over as a result of the collision, her bags, filled with what she had just bought from the market spill out onto the ground and you wind up laying on top of her.

>You blush beet red and quickly scramble to get off her, then you offer her your hoof to help her up, which she accepts. "I'm so sorry!" you say as you scramble around, helping her pick up her bags.

>"Oh it's quite alright darling, accidents do happen. Say, you're that mare that orders my dresses through the mail aren't you? I recognize the one you have on." You nod as you check an apple for bruises before placing it in Rarity's saddle bag. "

>Its nice to finally meet you, I always like to get to know my clients, care to talk a bit? I was just heading back to my boutique."

>As you both arrive at the boutique, Rarity hold the door open, inviting you in. You usually have a hard time refusing offers and this was no exception, especially with the white mare staring at you with her gorgeous blue eyes.

>You step inside and she follows, setting her bags on the table and grabbing her measuring tape and a note book.

>"Now about that dress!~ If you don't mind, I'd like to take your measurements to ensure a perfect fit, you'll have to take your dress off of course, so the measurement is accurate. "

>You stutter a bit, wearing a blush like it was a fashion accessory now. You slowly start to take off your dress, though only the sleeves and part covering your chest and back, leaving your rear half and legs still covered. Rarity goes to work measuring the part of your body you have revealed.

>"Hmm… okay, good, now lets see the rest." You use your magic to lift your dress a small bit, barely holding your floor length dress up enough to reveal your rear ankles. "Oh you don't have to be so shy, its just part of my job, but I really need those measurements, getting a good fit around the flanks is one of the most important parts of making a dress."

>You blush as she begins to measure your enormous package, "I.. I don't think these measurements are needed for…. the dress…" you finally pipe up.

>"Shush~ I know what I'm doing darling, now bend over so I can get that last measurement~"

>You feel its for your best interest to not resist, a popular mare like her could tell everypony your secret, plus the silky sound of her voice in your ears just makes you want to obey. You bend over to let the seamstress do her work

>You let out a small yelp as Rarity slowly sticks her horn into you, you can't help but get aroused as you hear the mare moaning behind you, sliding her horn in an out.

>Your huge cock begins to swell and harden growing much longer and thicker than it was while flaccid. Rarity begins to lick at you from behind, caressing your large balls with a hoof as she pegs you with her horn. Her hoof reaches to rub you now completely erect, meaty appendage

>You gulp as you look at the huge puddle of your seed, and feel the mare's firm but gentle hoof pushing your face down into it. "It will be easier while it's still warm~" you hear her say.

>You bend down and begin to lick your own cum from the boutique floor, cleaning up every drop as Rarity demands.

>You finish, and she puts her hoof under your chin, bringing you up for a kiss. You're amazed at the experience you just had. Not only was it pleasurable, but you feel so accepted, Rarity knows your secret, and…well this was certainly a positive reaction.

>She tells you that she has something planned for you tonight, and she wants you to return to the boutique at sunset.

>Rarity keeps her promise of free dress, more comfortable than any of the ones you had previously owned, especially since it was made with your...
uniqueness in mind.

>You decide to finish your shopping, an easy feat now that the market has calmed down then returned home to pack up what you bought and rest a bit, you had the feeling your night with Rarity would be a long one indeed. As evening approaches you make sure your new dress is put on neatly and head towards the Carousel Boutique.

>You look around and blush, you immediately recognize three of them, Applejack, the orange mare who sells the apples, Pinkie Pie, the assistant at Sugarcube Corner and the purple unicorn, who organizes the Winter Wrap Up each year. The other two you're not quite sure, one you know is on the weather team though.

>You shuffle over to Rarity and whisper into her ear, "I thought it was going to be just us…"

>"Oh I'm sorry, I should have told you I planned to invite my friends over, darling~"

>You chat with Fluttershy for a bit, as she tells you about her life in the relative seclusion of her cottage on the edge of the Everfree forest when Rarity manages to catch your attention

>Rarity gets your attention my clinking loudly on a glass, getting everyone's attention. "Come have a seat everyone." She has a seating area arranged, all facing the same direction. She stops you from sitting though and guides you to stand in front of everyone else, Rarity still by your side. "I'd delighted you've all had a chance to get to know Is our name, Anon like usual? Anon tonight. I bumped into her this morning at the market and afterwards we really got to know each other."

>You start to worry about where this is going.

>"She's been too shy to make many friends, and when I got to know how wonderful she is, I just couldn't let her go another day hiding herself away."

>You now have no doubt about where this is going.

>You speak up. "Rarity, please, I'm not ready." "Now now, you're only nervous because you think something bad will happen if other ponies see. The best thing to do is just get it over with and see that everyone here is excited about what you have to offer."

>The other 5 are clearly confused.

>"We're all friends now." Rarity says, "And after all, friendship is magic."

>As she says this she magically lifts your dress and nudges you to face away from the group so everyone can see.

>You blush heavily as Rarity show her friends your secret, displaying your plump flanks, huge balls and cock, gigantic even in its flaccid state. "Rarity, please no!" You say, it not quite registering in your mind that its far to late to resist now.

>Your body obeys her gentle push, and you turn, exposing yourself to the group, even as you whisper, "Rarity, please no!"

>You can only hear their reactions.

>"Tarnation!" You hear from AJ, "That's even bigger than Big M…" She stops herself before she finishes saying something she already regrets.

>You hear a quiet squeak from Fluttershy.

>"Wow!" You hear from an excited Pinkie Pie, "I can't believe you've been hiding that all this time! If I had something so super-duper neato I'd want to share it with everyone in town…" She continues talking a mile a minute while running all around, checking it out from every angle.

>"Rarity," Twilight addresses the host, "this is amazing."

>Rarity rests your dress on your back, leaving you exposed. She magics a hair clip over and clips your tail to your mane so it's out of the way. She then puts a hoof on your shoulders and again has you bend all the way over, front knees on the floor, hind-quarters raised all the way up.

>After bending you over, Rarity walks behind you and kicks your legs apart.

>Your legs tremble. Nopony reacted negatively, but you're still extremely nervous. You've successfully hidden this for so long, it's quite the shock to suddenly be on display like this.

>You feel a hoof on your face and look up.

>It's Fluttershy. She's gently stroking your cheek.

>"I know you're embarrassed. I'd be embarrassed in that position too, and I don't even wear clothes most of the time." She brushes your mane. You feel comforted and your legs tremble a bit less. Fluttershy stays by your face, caressing you looking into your eyes with a soft smile.

>You hear Twilight behind you. "I've read about this. You're a futanari, right?" You can feel her breath when she speaks, she's inspecting you so closely.

>"Y-yes." You manage to respond.

>"I've never seen anything like it." She says as you feel her hoof on your inner thigh.

>"What's the big deal?" You finally hear from Rainbow Dash. "It's nothing we haven't seen before. Just…never on the same pony. Alicorns have wings and horns, is this really that different?"

>That's an interesting way of thinking about it. You'd always felt ashamed, but you like this alicorn analogy.

>"This is even rarer than being an alicorn." Twilight says, tentatively touching you, much more gently than Rarity had. "Is this alright?" Twilight asks. "I don't want to hurt you."

>"I…I trust you." You stammer.

>Fluttershy kisses you on the forehead.

>"I know you're scared, but she'll be very gentle." She continues caressing and comforting you. Twilight slowly runs her hoof up and down your length, sliding the loose skin over the turgid shaft beneath. Going downward, she stops just short of the tip, which at the moment you're thankful for, since you'd feel embarrassed if she got any pre-cum on her hoof, and you're sure there's a small puddle by now.

>Going upward she stops just before your balls, which hang downward quite a bit.

>Pinkie Pie joins Fluttershy in front of you. "That thing looks like so much fun! We're all back there watching Twilight play with it and it's just incredible."

>You close your eyes at the thought of 5 of them back there watching you.

>"I'm not playing Pinkie, this is for science." Twilight retorts.

>"Are you alright?" Fluttershy asks, seeing your eyes closed tight.

>You open them. "It's just…everypony watching me, it's…so humiliating."

>"Do you want me to ask them to stop?" Fluttershy asks.

>You feel Twilight's hoof.

>"I…I don't want them to stop. It feels so good…and…I've kept this a secret so long, I've never felt anything like this."

>"But if it feels so good, you should have fun with it all the time." Pinkie interrupts, "Don't you do anything with it?"

>"Well…I…I have some fun…alone." You say.

>"Alone?" Fluttershy asks.

>"I…I masturbate, since I'm too scared to show it to anyone."

>"And that's all you've ever done your whole life?" Twilight asks, still stroking you lightly with one hoof.

>"Until today." You add.

>"So earlier today…" Rarity asks, "That was the first orgasm you ever had with another pony?"

>"Yes." you admit.

>"Y'all had a romp earlier today?" Applejack asked.

>"How do you think I found out about her, darling?"

>Twilight stops touching you. "Can you show me what you did?" She asks Rarity.

>"Of course." She offers.

>Rarity puts her hooves on your plot once again and spreads your cheeks open.

>Pinkie bounds back behind you to watch.

>Fluttershy stays near your head, comforting you.

>"You'll all be able to see better if I just tell you what to do." Rarity says, holding you open.

>"Pinkie, put your hoof here." She places Pinkie's hoof on your balls and moves it in small circles. "Just play around as you like."

>Pinkie juggles your testes with both her hooves, weighing them and bouncing them and giggling.

>"And then I massaged her with my horn…here." Rarity says putting a hoof directly on your anus. "Twilight, maybe you could do the honors while I hold her open for Applejack and Rainbow Dash to see."

>Tentatively, Twilight does as instructed.

>Your puddle of pre-cum has reached your own hooves now.

>Twilight slides her horn in and out of you. "How does this feel?" She asks.

>You cry as Fluttershy pets you. "It feels wonderful." You confess.

>"And Rarity made you…cum?" Twilight asks, "Just like this?"

>"Yes." You admit as Fluttershy wipes some tears from your cheek.

>"Speaking of which…" Rarity says.

>You feel Twilight's horn and Pinkie's hooves leave you.

>"You're making a mess again." Rarity continues.

>"But Rarity," You protest, "With 5 other ponies here…"

>"Lick it up, just like you did before." She says as you hear several giggles from behind you.

>Rarity comes in front of you and lifts your chin with her hoof.

>"Turn around." She commands gently.

>You turn to face the rest of the group, and you see that this extended session of teasing has produced a puddle of pre-cum nearly as large as your orgasm this afternoon.

>"If I spilled something in your home, I'd clean it up." Rarity said. She gently pushes your head back to the floor, and you lick the floor. The assembled ponies don't take their eyes off of you for a second.

>Once you're done, Rarity pats you on the head, saying "Good girl, now we can have some more fun."

>You look at the group.

>"Twilight, I think it's time to give someone else a turn." Rarity says.

>You glance at Applejack, and quickly glance away.

>Rarity noticed. "Aww, do you want to see what Applejack wants to do with you?" She asks.

>Applejack blushes, "Gosh, I never played around with one so big before."

>"Well what did you have in mind, dear?" Rarity asks.

>"Well, I was gettin' a few ideas seeing you bent over like that.

>"Oh really?" Rarity says, guiding you to your former position with her hooves.

>Applejack walks over and sits down so as to use both of her front hooves. She compresses your girth tightly between her hooves. "Ah could actually use some help wit this." She says. "Dash, you're pretty strong, care to lend me a hoof?"

>You feel a second set of hooves on your shaft, and you feel Rainbow Dash next to your thigh, so as to get a perpendicular angle to Applejack.

>"Now just follow my lead." AJ says.

>The four hooves began stroking your length. Each time they got to the top, they'd hit your balls, knocking them upward.

>"Doesn't that hurt?" You hear Twilight ask.

>"Yes…" You gasp, "don't stop."

>At this the two ponies stroking you go faster.

>You whisper as loud as you can, "I…I'm going to…ahhh." You cum, splashing the legs of the two ponies near you.

>"Wow!" Pinkie exclaims. "I've never seen so much!"

>"You could have warned us." Dash said, clearly annoyed.

>"She tried to." Fluttershy interjected. "You were stimulating her so much, she could barely speak."

>Rarity lifts you by your chin again. "You've another mess to clean up, darling."

>You turn and see AJ and Dash's splattered legs. You step forward and begin to lick.

>"Not like that dear." Rarity says. "With mares like this, you have to be more gentle. Now kiss and suck, don't just scrape with your tongue."

>You start with AJ, kissing her legs and thighs and sucking your cum off. AJ seems to be enjoying your attentions, and that's when you notice Fluttershy is helping you, licking your cum off of Dash's leg. You look over at her.

>"Rarity said I could help, but she said I couldn't use a towel." Fluttershy explained.

>Once the two ponies were cleaned up, you turned to see Fluttershy bent over licking your cum off the floor. You take note for your surroundings:

>Fluttershy, bent over in front of you, lapping up your cum.

>Applejack, giving you a look like she didn't want you to stop licking her.

>Rainbow Dash, looking like she wanted Fluttershy's tongue back.

>Twilight and Rarity, discussing something secretively.

>Pinkie Pie…taking pictures. Oh great.

>You go to find out what Twi and Rarity are talking about.

>Twilight addresses you as you approach.

>"Rarity reminded me that there's a part of you we've been neglecting."

>"Yes, darling, and Twilight tells me that your physiology probably allows for two distinct types of orgasm." Rarity added. Rarity's horn glows and she brings two large strap-ons into view. Not as large as you, but considering they're about to go into you, pretty intimidating. Rarity and Twilight affix the accessories and walk with you back to the seating area. Rarity positions you and you feel Twilight mount you and line herself up.

>"Applejack, dear, would you come here please?" Rarity says.

>Applejack comes over. Rarity faces her away from you.

>"This is your first time, and I don't want to hear any garish screaming, so you just keep your face nice and snug here." She presses your face to AJ's plot. 

>Twilight takes this moment to enter you.

>You scream into AJ's marehood and she sighs as Rarity holds your head in place.

>After a little while, it doesn't hurt as much, and you calm down and really focus on AJ. It takes some time, but you get her off. She soaks your face with mare juices.

>"Does this feel good? Am I don't something wrong?" asked Twilight, still penetrating you.

>You moan and Twilight takes this as in indication that she's doing alright. You intended to return to Applejack, but instead you find Fluttershy, eagerly licking AJ's juices off your face.

>"I cleaned up the whole floor for you. Are you doing alright?"

>You nod.

>Twilight slips out of you, and backs away. "Did you cum? I couldn't tell? Did I do something wrong?"

>"I don't think so." You reply. "But that was amazing, you did everything right."

>Twilight smiles.

>You feel something else behind you.

>It's Rarity.

>She mounts you and just teases your opening with her toy. "Beg for it." She says.

>"…Please?" You reply.

>She stops teasing you with it. "You'd better get good at this quickly." She teases with her words.

>Fluttershy whispers in your ear and you repeat her words, "Please fuck me. Fuck me and make me your slut. I need you, I'm going insane without you inside of me. I'm already yours now claim me!"

>Rarity seems convinced, and enters you.

>You look with shock at Fluttershy, not sure if she was just being helpful, or if she was speaking to you.

>Rarity bites your mane and pulls on it as she fucks you.

>You feel something growing inside you, different than your previous orgasm. You suspect what it is, but you don't know how to get closer.

>Rarity whispers in your ear, "Ask my permission."

>You feel it now, "May I cum?" You ask her.

>"No." She says and increases her speed.

>You can't tell if you're disobeying her, you're legitimately not sure.

>"I…please….it's…you…please…need…Rarity." You babble.

>"Not yet," she says, "not til I tell you."

>Fluttershy starts frantically kissing you all over your face. "Rarity, don't hurt her." Fluttershy says.

>Rarity leans forward and bites your ear as she says "Now", and thrusts all the way into you.

>You scream so loudly you scare Fluttershy as your first vaginal orgasm shakes your body. You sort of lose track of things for a moment, you don't pass out but…which direction you're facing is confusing for a moment. When you regain your composure five the ponies are looking down at you.

>Rarity with a knowing smirk, Fluttershy looking terrified, Twilight looking jealous, AJ looking happy for you, RD looking worried about you, and Pinkie Pie is jumping all over the room. "Woohoo! You know what this calls for? A party!"

>"Fluttershy…" you say, "those things you whispering in my ear…"

>Fluttershy blushes deeply, all eyes turn to her.

>"Did you mean them?" You ask.

>Fluttershy crouches on the floor, and emits a quiet squeak.

>"That's a yes." interjects Rainbow Dash, rolling her eyes.

>"It's getting kind of late," says Rarity, "Perhaps you should walk Fluttershy home."

>"But it's not…" Twilight is cut short by a nudge from Rarity.

>"You're right, Rarity." says Pinkie, "And Fluttershy can't walk home alone, she lives too close to the Everfree Forest."

>Everyone says their goodbyes and you leave with Fluttershy.

>You start a conversation with her on the way to her cottage.

>You soon arrive at Fluttershy's cottage, she politely holds the door open blushing. "Um…feel free to come inside." You do and she enters after you, closing the door behind her.

>The cottage is a small, cozy building, the bottom floor being a sort of den or living room, you assume the bedroom is up the stairs the yellow pegasus is looking at. She looks back at you and blushes, giving a shy smile.

>Fluttershy slowly begins to ascend the stairs, and you follow her. She pulls some striped socks from her nightstand and slides them over her hooves.
"I've had these for a while, but I've never actually tried them on before…" She lays on the bed looking at you, her hindlegs spread slightly behind her. "…How do they look?"

>You blush heavily as you feel your dress lifting on its own, the reason made apparent as you feel your a warm throbbing in your member, a large bead of pre-cum forming at the tip.

>Fluttershy blushes as she stares at your rod. "Oh my… I.. um… oh my." You're surprised yourself at how quickly the sight of the mare on the bed aroused you. You blush and remove your dress, nervously climbing into bed next to her.

>You lie on your back, your massive rod jutting into the air as Fluttershy lies on hers, spreading her legs and blushing. Both of you sit there for a moment that seems to take forever, waiting for the other to make the first move. Slowly you sit up to take the lead, leaning over the mare to give her a kiss. You slowly line up your cock with her lower lips, already leaking pre-cum all over the sheets and lean in penetrating her.

>She practically screams out of pleasure as your very thick member enters her tight passage. You slowly continue to slide in, unsure of how much the petite mare could take. You close your eyes and wait for your tip to hit something or just stop being able to go in, to be honest you had no idea what to expect. You open your eyes as you feel your hips hit against the pegasus' flanks, your entire cock inside the shy mare, her moans more like joyful gasps at this point.

>You slowly begin to slide in and out of her, trying to imitate the motions Rarity made when she fucked you with the strap on. Neither of you lasted very long, but Fluttershy reached her climax first, the feeling of the mare contracting around you as her whole body tenses up pushes you over the edge, you moan loudly as your enormous cock pumps her full of your copious amount of seed, her passage quickly overflowing as it begins to spill out around your cock.

>You pull out as you continue to let your seed loose, spurts of white covering both you and Fluttershy and soaking her bed, when your orgasm finally stops,you lean forward over the mare, still reeling from her orgasm and cuddle with her, both you and her soaked in warm cum.

>You wake up and find both of you almost completely covered in dried cum, the bed too, as a result of last night. You awake Fluttershy with a kiss, she responds with a blush and a smile. She pulls you closer for another kiss, and snuggles against you a bit.

>The two of you climb out of bed, Fluttershy begins to slide her socks off, revealing her legs are the only part of her not covered in cum, you tap her shoulder and suggest that she leaves to socks on for now, you really like how she looks in them.

>You and her head downstairs, she insists you take a seat while she makes breakfast. You oblige as she gets to work making <vegan breakfast food>, you find yourself staring at her flanks as she goes about preparing the food, causing you to blush when you notice you're doing this.

>She sits down next to you and you eat together. As you finish and set your bowl on the coffee table you hear a knock at the door. You answer the door to find Twilight and Rarity smiling at you as they walk into the house.

>Rarity looks at you two oddly, "Are you covered in...?"

>You and Fluttershy blush simultaneously, suddenly remember you haven't cleaned up from last night. "I… um… uh…" you squeak out.

>Rarity snickers a bit and insists you two don't clean up. You blush and nod, so does Fluttershy, you both think its really embarrassing but you also like to do what Rarity tells you. "I take it you two had fun last night?~"

>Rarity invites you to brunch with her friends, you ask if you can at least but your dress back on before you leave. "Oh I made you a new dress, darling~" Rarity grins as she pulls a much skimpier dress out of her saddlebag, offering it to you.

>You accept and put it on, you must admit it's quite comfortable, then you realize, it caresses your equipment so well because it was practically designed to show it off, fitting tightly against the form of your balls and flaccid cock, the stretchy fabric even giving the slightest outline of your marehood if you were to lift your tail.

>"Now come along sweetie~ we don't want to be late now!"


>You blush as Pinkie laughs, barely able to make eye contact with the mare. "I'll, um...uh…have a cupcake, I guess…"

>"Why don't you show off your new dress for Pinkie darling~" You blush even heavier as you hear Pinkie let out an excited "Ooh!" as she steps out from behind the counter. You stand still, trying to model for Pinkie the best you can without explicitly showing off your stallionhood. "Now lift your tail and spread your legs so she can see the best part."

>You turn around and show off your plot for the mares, you almost hate to admit it, but doing what Rarity tells you to almost turns you on now.

>You lower your tail as Rainbow Dash and Applejack arrive and Rarity pipes up, "Ah ah ah, who said you could do that~" She lifts your tail with her magic and pins it to your mane to hold it out of the way, just like yesterday evening.

>As you show off your outfit to the two mares that have just joined you and listen to their comments you can't help but feel embarrassed…and aroused. A wet spot begins to form both between your flanks and at the tip of you member as the fabric stretches to compensate for your arousal

>"W-we're covered in… my… cum.." you stutter out to the mares. "And what else is covered in it?~" you hear Rarity ask.

>"Fl-Fluttershy's mattress is…soaked…" You and Fluttershy are blushing very intensely as you sit next to each other. You hear Applejack mumbling something but all you can make out is something about being "Worse than when Big Mac and Braeburn..." and something along the lines of "They were both stallions." Rainbow Dash looks slightly impressed and Twilight mildly jealous as she watches you sit next to Fluttershy, the wet spot of precum on your dress slowly growing larger.

>"I've also made some more outfits you two~" Rarity says as you enter the boutique. You look at the outfits she has, realizing they are very skimpy versions of a maid's uniform. She sets them on the ground next to you and Fluttershy. "I'll let you two dress each other~"

>You nod and look at Fluttershy, blushing just as much as you, you begin to dress her in the maid outfit. "Now it's your turn darling~" Rarity says as Fluttershy starts to nervously undress you and redress you in the maid outfit. As soon as she finishes Rarity lifts Fluttershy's tail and pins it to her mane, just like yours.

>Rarity smiles and holds up two toothbrushes. "Now be a dear and clean the boutique floor for me~" She places one in your mouth and one in Fluttershy's.

>Not wanting to disappoint the beautiful mare you bend down and begin scrubbing the floor, Fluttershy doing the same with you. As you're bent over with your rear still high in the air your legs naturally spread and with your tail pinned into a lifted position you have no choice but to show off your plot, every part of your rear clearly visible to onlookers.

>The other four mares watch you closely as you scrub the floor. Applejack mutters quietly "This is better than watchin' Big Mac work..." and Rainbow Dash enjoys the clear view of Fluttershy's marehood as she works, flying around the boutique to ensure she has the best angle to watch from.

>Pinkie just seems to appreciate you both in general as she bounces around on the now very clean sections of floor. You feel Twilight occasionally groping you or fondling your balls, claiming the defense of "scientific research."

>You can't deny this is embarrassing yet you also find that arousing, your meaty horsecock beginning to perk up as you drip precum on the floor you just cleaned. "But darling, you just cleaned that, what are you doing making the floor messy again? Are you going to clean that up or should I have Fluttershy?" Rarity points to the puddle of precum forming under your semi-erect penis.

>"I'll just have Fluttershy do it~" Fluttershy drops her toothbrush and comes up behind you, her ears brush against your shaft and you start to move away when Rarity tells you to stay right there.

>Fluttershy does her best to avoid contact but this soon turns futile as the only precum left is closer to your cock, she goes to lick that up, her head and soft mane brush against your stallionhood and she occasionally licks the tip. This only serves to arouse you more as even more pre starts to leak from you, the puddle on the floor growing much faster than she can lap it up.

>You hear the mares giggle as Fluttershy desperately tries to keep up with the ever increasing amount of precum dripping from your turgid cock.

>"You're going to need it all of you want to make any progress, honey, perhaps you should empty the source first~" Rarity suggests.

> Suddenly you feel lips wrap around your thick head as you grow fully erect. You look between your front legs and back at Fluttershy, watching her cheeks puff out then empty as they fill with your leaking precum and she swallows, eventually she gets the rhythm of constant swallowing the flow rather than taking it mouthfuls at a time.

>She teases the head of your equine prick with her tongue as she rubs your shaft up and down, you feel yourself closer and closer until you finally cum into the mare's mouth.

Her eyes widen and cheeks puff out as you flood the mare with your seed, she can't keep up and pulls away, getting blasted in the face by your powerful ejaculation, covering her face in cum, the rest of your massive load emptying onto the floor in a large puddle.

You offer to wipe your cum off her face, but Rarity stops you, like the dried cum from last night, she forces Fluttershy to keep it on her. "Now look at the mess you made! Is like you don't want this floor cleaned at all." She says pointing to the massive puddle of your seed on the floor below you and Fluttershy.

>Rarity looks over the floor, "I'm sure thats more than even you two could handle licking up...perhaps Fluttershy could use that lovely main of hers like a mop?" Rarity suggests. 

>Fluttershy looks around, cum still dripping from her face.

>She begins to rub her mane against the floor, her silky hair absorbing the mess with ease. As she mops it up her hair becomes soaked and it gradually becomes harder for her to clean it up as she has to rub her head against the wet floor over and over to soak anything up.

>When she finally gets it all soaked up it leaves her mane heavy and wet, dripping with your cum. Rarity shrugs and says that will have to do…for now. She asks you two to stand close together and stay still as she takes out a camera, taking a picture of the pegasus mare and you from the front, side and several pictures from behind.

>Twilight whispers to Rarity, who whispers back and nods. Twilight approaches you with an offer to take you back to her home for some research. You realize you have nothing better to and getting a break from Rarity's control might be nice, no matter how much you enjoy it, and science can't be that bad…right?

>As you're lead to the library Twilight removes the hair pin holding your tail up, guessing you'd appreciate the small bit of modesty, there doesn't seem to be anypony outside, being a cloudy day, but you still thank her, better safe than sorry.

>You enter the large tree that is the town library and are led through a door, Twilight hanging a "do not disturb" sign on the knob as she closes it behind her, you descend a flight of stairs to a small lab set up in her basement.

>"This is where I do my research! Not as nice as the lab back in Canterlot, but it's something." The purple mare seems very proud as she explains her equipment. "Now lets get you out of those clothes and cleaned off, don't want anything interfering with the scientific method."

>Twilight begins to pull your outfit off, which being completely naked in front of Twilight almost felt less embarrassing. You feel her lift you up with her magic as it begins to scrub the dried cum from your coat before being set down, so clean you'd compare it to the sterilization of medical equipment before procedure.

>She asks you to stand in an oddly specific position, down to how many millimeters your rear hooves should be spread apart. She then asks you politely to raise your tail, which you do.

>Twilight looks between your legs, blushing a bit. "I'm sorry…its just I've never seen these so close before last night at Rarity's, on a stallion and definitely not on a mare!" After a brief moment moment she grab her tools and begins to measure everything; your flaccid length and girth, which she compares to the length and circumference of your torso. She measures your balls and how far she can spread your flanks apart.

>"I couldn't find much information but for now I'm going to theorize that futanari mares have a larger penis and testicles than stallions, because its statistically unlike for you to be born a futanari and this far above the average size. Now I just need to take one more measurement."

>Twilight begins to rub your shaft up and down, cuddling her flanks against you as your cock begins to harden. As your dick swells pre-cum begins to drip from it, as usual, but what surprises you is Twilight slides what feels like a tube over the head, collecting your pre-cum in a large jar. "Hope you don't mind, I might need a lot for research later." She continues to rub your member until she's sure its fully hard, then she carefully measures it.

>Asking you to roll on your back she examines your balls and throbbing appendage more closely. She runs her hoof from the base all the way up to the top, measuring your reaction. She gently rubs the tip of your cock with her hoof causing even more pre-cum to be teased out. She continues to prod and rub you, writing notes on your reactions. You moan as she continues to tease you, almost constantly on the edge of an orgasm but never entirely pushed far enough.

>Twilight continues to tease you then suddenly stops, practically begging for an orgasm after all that build up. She pulls the the tube collecting your precum off of you, the huge jar completely full.

She looks over her notes and looks to you, she nods and begins to prepare a spell, which she casts on you. You feel an odd tingling in your balls, then suddenly the amount of precum flowing from your dick increases dramatically, and you can literally feel your balls churn as your cum production increases. Twilight lets out a satisfied "Aah!~" and prepares another spell.

>As she casts this one you let out a gasp as your package begins to literally grow before your eyes, becoming even longer and thicker than before. Twilight looks very happy, "My spells worked! The first time I tried them too!" Twilight leans over you, looking at your enlarged cock before placing her lips against it.

>She starts to suck your engorged member, barely able to even fit her lips around it, bobbing her head up and down and slowly rubbing it from top to bottom with her hooves. You're able to do nothing except lay on your back and moan as she wraps your cock with her magic while she sucks and rubs its, squeezing your cock tightly in all the right ways.

>When you finally climaxes she holds her mouth over your head as you begin to deliver your payload, however she and definitely not you were not prepared for exactly how much her previous spell had drastically increased your cum production from its already huge volume. She quckly pulls away from your cock as the flood of cum begins to hose her down, and gets all over you. Your orgasm seems to last forever as your cock produces rope after rope of your thick, white seed. Both you and Twilight are left covered and dripping in cum.

>Twilight nuzzles your cock and begins to clean up the mess you've made. "Well that worked even better than expected…though I did forget to take notes…I don't know what came over me! Well…you came…all over me and yourself…and…the lab…" "Maybe I should try to collect a sample in a neater fashion… " she says as she goes to her closet, pulling out what looks like a milking machine, for a cow, yet modified…somehow…like it was mixed with a vacuum cleaner almost. She turns the machine to show you, indicating you slide your cock into the end here.

>She turns the machine on and immediately it feels amazing, you blush and scream out of pleasure as it pushes you over the edge almost instantly, bringing you into a constant orgasm. Twilight watches the machine milk your cock. "I hope you don't mind if I test another spell out."

>You look behind you to see Twilight cast a spell on herself as she grows a massive cock and pair of balls, not as big as your exaggerated equipment, but still very large. You would worry a bit about her plan but you're unable to truly focus with the machine working its magic.

>Twilight looks absolutely exhausted from the strain of casting the spell, but also quite proud of herself. You feel her hoof on your shoulder and also something else pressing against your flanks. Slowly and cautiously Twilight leans in, sliding her stallionhood into you. She moans loudly as your tightness wraps around her while she pumps your marehood.

>As she fucks you she starts to pound harder and harder, delivering a final hard thrust as she unloads her seed into you, you're almost lost in the pleasure as you experience your second vaginal orgasm at the hands of another mare. Twilight moan and slumps to the ground, cuddling against your flanks. "Ooh~ I'm…keeping this~" you hear her say.

>You fill the machine's large tank, and it kicks off automatically as you slide out of it and lay on the ground next to Twilight, just as, if not more exhausted than her.

>As you lay on the ground you feel Twilight cast the spell from earlier. "Just one more test!" she says as you feel a weird but pleasant tingling in your balls. Twilight holds the spell a bit longer than last time before she finishes casting. "Oops…"

>"W-what?" You ask.

>"I think I might have over done it a bit…"

>"What does that mean?"

>"Well, you'll still make more…cum…than before…a lot more…you'll see. But for now I think need another…sample."

>She rolls you onto your back and grinds her body against yours, your cocks, both still semi erect, rub against each other and both you and the purple mare become very aroused quickly. She sits up, holding her meaty penis against yours as she rubs them up and down with her hooves, she leans over and begins to suck on the head of your cock, noticeable bigger than hers.

>Feeling another warm, fleshy cock throbbing against yours is a whole new experience of its own. You reach your hooves out to pleasure Twilight's cock as it only seemed appropriate to return the favor. You moan louder and louder and you guess Twilight would be doing the same if her lips weren't locked around the head of your cock, but you can feel her heart rate increases by the throbbing of her member.

>You're both pushed over the edge as Twilight begins to shoot herself in the chin with her own seed, and you begin to fill her mouth. She presses her head down as hard as she can, swallowing frantically, let as much as she wants too she finds herself unable to swallow it all, her cheeks puffing out and some cum leaking out of her nose.

>She pulls away as your cum sprays out, yet she still tries to drink it all, before you finally feel emptied for now. Twilight leans back and rubs her belly, "I think that sample will do great for now~" You lean back too, realizing how heavy your balls feel already, despite the huge amount of cum you had just pumped out. The two of you both lay back and relax for a bit.

>After you rest Twilight gently nudges you suggesting that you and her should go upstairs. She checks the clock in the library "Wow…that's late...maybe you could spend the night here…I don't mind sharing my bed…" Twilight blushes and begins to walk upstairs.

>She lies down in her bed and smiles at you, you climb in bed next to her, you lay back to back in the bed, but even then you find the idea of being in bed with another mare arousing. You feel Twilight roll over behind you and something warm and hard press into your back. It doesn't take you long to
guess what, but what surprises you is that her hoof wraps around you and touches your member. You blush and moan slightly, rolling over to find Twilight fast asleep, you smile and slowly drift off yourself.

>You wake up the next morning to Twilight tapping your shoulder, who had apparently been up for a while, which you thought was insane considering you normally don't wake up even this early most days, she says Rarity was asking you and here to come back over. As you climb out of bed you feel like your balls have gotten heavier, you look back to find they have swollen to be even larger.

>You whisper to Twilight about the swelling and she nods before the two of you walk with Rarity towards the boutique. When you arrive the other mares are there…of course…Twilight had explained that you need some release fairly often or you could experience fairly painful swelling because of her mistake with a spell, Rarity just smiled and nodded, from what you've learned about her so far you hardly expected it to be good. Your suspicion was confirmed as she politely asked you to roll on your back and begins to fit some sort of locked belt over your member, stopping it from being able to be touched.

>You sit in with them as the six have a friendly conversation, but all you can think about are your swelling balls, eventually to the point where the pain becomes noticeable, you gently tap Twilight's shoulder and whisper to her, and she then whispers to Rarity who smiles.

>"It looks like Anon here could use a bit of relief, you have that wonderful new tool of yours, Twilight, why don't you tend to her?"

>"Rarity, I'm not sure that would help…"

>"Try anyway darling~"

>You and Twilight stand up and you, desperately wanting something to let the growing pressure In your loins off, you bend over in front of he rand present your plot, comforted by the fact that you know she'll be gentle. Staring at your marehood between your plump flanks she has no trouble getting her stallionhood up and ready and she slowly mounts you, leaning in to penetrate you.

>Nornally your own stallionhood would be getting aroused, which you fear might be a bit painful in your current situation, and you'd already be leaking precum all over the place, until you realize the belt is enchanted to make it impossible for your cock to become aroused or orgasm and it holds in any precum which only serves to make your balls swell faster.

>Twilight pumps at you with her throbbing cock it feels amazing yet you also can't get over the growing pain in your testicles, growing even worse when Twilight cums inside you causing you to orgasm vaginally yourself. As Twilight pulls out you slouch forward, almost in tears from the pressure in your balls.

>"I think that's enough for now darling~" You hear Rarity say. She joins Twilight behind you, gently touching her hoof to your balls. "P… please just take this off!" you beg. Rarity, ignoring your pleas, begins to fondle your balls. "Mhmm~ you have gotten quite big~ but it wouldnt hurt to be bigger. .. that badly now would it?~"

>Rarity leaves the belt on as she continues to tease you. She invites Applejack to join her, "Ah've always wanted ta get my hooves on a pair this big~" you hear as she begins to play with you. You're balls continue to swell as the mares tease you like a toy for the better part of the day leaving you massive and incredibly swollen, crying from the pain.

>"Hmm, I think she finally deserves some release~ What do you think Fluttershy?~" You hear Rarity ask.

>"I-yes," she says rather meekly. You hear the jingle of keys before a pressure on your back. The latch releases and the belt clanks off of you. Your junk reacts immediately, your testes quivering and your erection painfully swollen from the neglect, leaking a steady stream of pre.

>"Well," Rarity says, "Go to it, Fluttershy." Still in the open stance, you turn your head and see Fluttershy walk up to you. She nuzzles your face, before crouching under you. You feel her breath on your head, causing you to twitch and leak another squirt of pre. She opens her muzzle and tries to envelop your member, she quickly finds out that it's an arduous task.

>You hear a snicker from Rarity before a cloud of magic envelops your waist. Against your will, you feel your hips moving forward, plowing into the unsuspecting pony.

>You were so close beforehand that this pushed you over the edge, cumming down her throat. Fluttershy tries to take it all in, but the massive amount is too much for her to handle as her cheeks puff up, semen streaming out from the corners of her mouth. She gets off of you, choking and coughing up an obscene amount of your fluid onto the floor.

>You on the other hand are still cumming, saturating Fluttershy's already soaked mane and coat with more of your essence; along with the wall behind her.

>Eventually your hooves fail you and you simply collapse, still leaking semen on the floor under you and your stomach, coating both of your parts in your own seed.

>Lying there, panting like a dog, you hear Fluttershy talk to Twilight. Fluttershy starts, saying "I-I don't like seeing Anon in so much pain, do you have any way to stop it from happening?" Twilight replies "Sure, every spell has a counterspell."

>You hear faint grunts of exertion and a magical bolt hits your genitalia from behind, specifically at your swollen balls. You feel the pressure receding and it feels like they've gone back to their original size, no longer producing cum like a factory.

>You try to stay conscious, but as the girls talk to themselves, you start fading into sleep from what just happened. You try to get their attention but you can hardly think as you sink deeper into the warm grasp of sleep. You close your heavy-lidded eyes and soon fall asleep.

>A sleepless dream, infinitely small and large passed you by as you awoke, finding yourself in a somewhat familiar room. Gathering yourself from the mental fog of sleep, you realize that you're back in Twilight's place.

>You feel a form besides you and you turn around, only to meet Twilight cuddling up against you. She presses herself into you, nuzzling your form as you feel her erection poking between you.

>She reaches around with her hoof and starts fondling your package, further rousing you from sleep. She starts rubbing herself against you, the frotting an alien but pleasurable experience. Overall, you would surmise that this was one of the best ways to wake up.

>She kisses you on the cheek, saying, "Good morning..." You nuzzle her in response, eliciting a giggle from the purple unicorn. She kisses you again, this time on the mouth. You reciprocate, opening your mouth to ask without words for her to do the same. She complies and you start wrestling your tongues for dominance. You two start rubbing against each other in this embrace, coating each others' rods, and Twi's bed, in your combined pre.

>You break the kiss, a strand of saliva between the two of you. Before she could ask you lean down and grab ahold of her smaller member with your hooves.

>Turning yourself to the other side of the bed, you get better access to her meat as you take the head in your mouth, licking her delicious pre and swirling your tongue around the broad flat of her erection. You haven't done this before, but you try your best as you take more and more of her meat down your throat, stopping before it became too difficult to breath, you manage to take in almost all of her.

>You start sucking on it, moving your tongue along her natural contours as she lets out a gasp. She starts leaking much more pre, which you happily collect as you further massage her, occasionally stroking her balls or massaging her feminine features.

>Twilight, not wanting to seem ungrateful, grabs ahold of your leaking member and tried to reciprocate. Your endowment, however, was making it tricky for her. After a few minutes and several attempts she finally manages to fit you inside her mouth, quite possibly stretching her jaw in the process. Shivers run down your spine as her maw engulfs you like a furnace, creating a vacuum seal from the outside world.

>You hear her cough and sputter, taking too much of your meat at once. You don't mind however as you quietly bob your head on her, making small noises as you slide her in your throat.

>Soon, you feel the telltale signs of her orgasm and you brace yourself. A liquid soon deposited itself in your throat. No choice in the matter, you swallow it down, quickly ascertaining its delectable taste.

>She stops and you're quick to realize that her orgasm was rather diminutive. You try sucking harder on it, determined to suck it out like a straw. No such luck prevailed however.

>You feel Twilight's magic upon your gonads again and you clench down, trying not to cum so quickly for the purple mare. Another bout of magic pushes past your resolve and you feel your seed travel up into the mare's awaiting maw.

>You hear more coughing as she tries desperately to drink it all down. It's like fighting a river however and she disengages, spilling your cum all over the bed and her as she quietly coughs and clears her nose.

>You sit up in the bed, watching Twilight try to cope with your seed. When she's finished she looks at you with a bewildered expression, like you just grew four mouths. This causes you to burst out laughing at how cute she looks. After a moment you see that she looks hurt, so you give her a hug, and say "I'm sorry."

>You break from the hug, realizing that you were tired once more; yesterday must of taken more out of than you then you realized. You give Twilight a final peck on the cheek before you settle back down into her bed.

>Twilight admires your feminine form before she gets up from the bed. Walking down to the library, she enters the magical spells section. Rarity had recently asked her to preform a spell, and right now would be the perfect time to try it out. she pulls out a book and flips through it, before stopping on a particular page.

>"Subtle Growth", the spell claimed, "grows the desired area slowly and painlessly." Perfect. Twilight, with book in tow, clamored silently back into the bedroom, readied herself for the spell to be cast. Her horn glowed a purple and she muttered a few phrases in an ancient and dead language before releasing the shot aimed at your masculine parts.

>You sleep through all of that, the only thing that would indicate anything was the feelings you experienced during your dream, but they were subtle and easily ignored while you went around your dreamworld.

>You sleep for what seemed like an eternity, not waking back up until midday. Sitting up, you notice Twilight was nowhere to be found, and neither were your clothing. Scrambling to find something to cover your exposed bits you manage to hit your head, causing Twilight to come up to check out the noise.

>Twilight laughed to herself when you explain the situation, trying your best not to expose yourself anymore than you already are. She goes down to another part of the house, before coming back and throwing some articles of clothing in your face, eliciting another giggle.

>You dress yourself and look down, only to adopt a giant blush. It was the maids outfit from earlier. Laced stockings that met with a black blouse that barely covered your feminine parts, god forbid your more shameful bits.

>You ask twilight if she has any other pairs of clothing, she replies, saying that it was the only thing Rarity would allow. After that discussion, you ask Twilight if you could go to Fluttershy's house, she says that would be fine. She purposefully fails to mention the spell she placed on you, much to her chagrin.

>You sigh, but steel yourself as you walk out of Twilight's front door, your deep shame leading way to a strange form of arousal, making it that much more difficult to leave with some form of dignity as you begin to carefully trudge to Fluttershy's place.

>You try to sneak to Fluttershy's house, but it seems that luck was not on your side. As soon as you stepped out you tried making you way to Flutter's house, focusing heavily on not being detected. Unfortunately a stallion sees you while you duck out of an alleyway and gives you a catcall, only furthering your shame and hidden arousal as you try desperately to hide your erection.

>Unbeknownst to you, the spell placed upon you works in lieu with your libido. The more aroused you become, the quicker the spell takes place.

>The stallion gives you another catcall and you lose it. You bolt out and run, full gallop, the rest of the way; your slowly enlarging futa horsecock and testes slapping against you as you run, leaking pre on the ground and your chest. You keep running in the vain hope that nopony would see you.

>You eventually arrive at Fluttershy's cottage, thankfully it was at the edge of town so nopony would be there. You were in a mess, your stomach stained white and a trail leading from town right to where your standing as your turgid shaft twitches in anticipation.

>You shuffle awkwardly up to Fluttershy's cottage and rap twice on the door in quick succession, pressing your hindlegs together in discomfort as you wait, your cock growing a bit larger underneath you.

>You hear the chain being pulled back, and a cyan blue eye peeks out at you. "A-Anon?" Her eyes drift down to your swollen nethers, before snapping back up to your face.

>"G-good afternoon, Fluttershy…" you say softly, her staring only making your condition worse.

>She opens the door further, grabbing your hoof and pulling you inside, before shutting the door and locking it behind you.

>You shift your legs awkwardly, looking up briefly into her stunning eyes, your long member twitching happily. "Fluttershy…could you help me out? P-please…?"

>Fluttershy swallows nervously as she catches another glimpse of your throbbing member, ""Th-the same thing happened last week! Oh, my…would you like me to be forceful again? I know you liked that last time…" she mumbles, poking your cock curiously with her hoof.

>You nod once as she nudges your swollen cock, your balls growing larger from Twilight's spell.
