Confused. That’s how you felt as you rushed to find the book.

“Oh, I know there’s gotta be one here, I have a book for everything.” You say as you recall the previous day’s events.

“Twilight, did you hear me?” Rainbow Dash asks. You nod.

You and Raindow dash are on your way to meet Rainbow Dash’s boyfriend. “I just want to let you know, I’m excited for you to meet Whiplash, n-not that it’s a big deal or anything.” Rainbow Dash says, catching herself before revealing too much emotion.

“Yes, I’m interested in this ‘special somepony’ of yours.” You say, galloping to keep pace with Rainbow Dash’s speed. You arive at a cottage house with daisies and roses surrounding the front porch. Wow, if there’s one thing about this pony, he sure has a lovely home you think as Rainbow dash descends and knocks on the door.

“Coming!’ Says a sing-song voice from inside the house. There is the sound of trotting and the door opens, revealing a very rough looking purple and teal pegasus. “Hey RD!” Whiplash, at least you assume it’s Whiplash, says. “And you must be Twilight, it’s nice to finally meet you!” He says, lifting his hoof in greeting. You shake hooves with him and Rainbow Dash trots up to him and gives him a kiss. Whiplash whispers something in her ear and she instantly turns red.

“Twilight, why don’t you come inside with us?” Rainbow Dash asks. “Sure!” You agree as you trot in. You look down and notice Whiplash’s cutie-mark. Hmm, a whip and hoof-cuffs, I’ve never seen that before you think as you sit down in a chair.

“That’s an interesting cutie-mark you got there Whiplash. Could you explain how you got it?” You ask. “Oh Twilight, allways the curious one.” Rainbow Dash says, rolling her eyes.

“Well yes Twilight, it is an ‘interesting’ cutie-mark and it is a bit of a personal story.” Whiplash answers. “Oh well if it’s personal then you don’t have to tell it. I’m sorry for invading your privacy.” You say, getting embarrassed.

“No worries, but I will tell you this, It’s called a ‘fetish cutie-mark’, and well it just means that I’m very good at pleasing ponies.” Whiplash says as he nuzzles Rainbow dashs mane. Rainbow dash giggles, then looks at you and turns red, instantly stopping her giggling.

“Lets talk about something else, like how the wonderbolts are going to be coming to Ponyville in just ONE MONTH!” Rainbow Dash shouts excitedly.

********

“Here it is! THE DATABASE OF ALL KNOWN TYPES OF CUTIE-MARKS.”

You say, reading the cover off an old, dusty book. You levitate the book in the air in front of your face and turn the page. “OK, ‘F’, let’s go to the ‘F’ section.” You say as you flip through the book. “Gosh they have records for all types of cutie-marks. From gardening cutie-marks to music cutie-marks. Ah, here it is, fetish cutie-marks. Now, let’s look for...oh my.” You say, turning red and green at all the pictures of ponies on display partaking in various sexual acts. “There’s some writing here, I’ll read it; fetish cutie-marks are one of the rarest types of cutie-marks because they usually aren’t an actual ponies ‘special talent’, (with the exception of the BDSM fetish cutie-marks) However, if a pony thoroughly enjoys a fetish, one may aquire a fetish cutie-mark.” You then begin flipping through the pages, each one making you gasp. “Wow, I never knew there were so many different ways people had intercourse. They have cutie-marks for everything; ungulaphilia, formicophilia, incest, rape, emetophilia, and ah, here it is, BDSM. There’s some more writing here; The whip and hoof-cuffs are usually for the dominant, sadistic role-player and the rope and tape is usually for the submissive, masochistic role-player.” You start laughing. “At least now I know how Whiplash got his cutie-mark. Hey, what’s this?” You ask as you turn to another page titled voyeur. “The binoculaurs are a cutie-mark usually designated for those who enjoy to watch sexual activities. Wow, that’s…interesting.” You say as you get an idea. “OK, so I really would like to learn more about these types of cutie-marks, study them and see the lasting effects they have, but to do that, I’d have to test on another pony, and that’d be unethical. It’d have to be with somepony I know I can trust, and that I’m friends with, AND that doesn’t have their cutie-mark. I think I know just who to ask.” You say, smiling as you head to bed, thinking of ways to conduct experiments.

“You want us to WHAT?!” Shouts an orange and purple filly. It’s two days later.

You’ve invited the Cutie-Mark-Crusaders to your library in the hopes of asking them to help you with your tests. They each give you strange looks, and you are afraid they might leave.

“I just want you to help me with a few experiments.” You say, innocently.

“Can’t you just have spike help you with it?” Asks Scootaloo.

“He’s on vacation with Little Strongheart. Besides, it wouldn’t work. I need you three specifically. “ You say with a smile.

“What do y’all mean ya need us?” Apple Bloom asks curiously.

“I just need to make some tests regarding the effects of cutie-marks and how somepony gets one.” You answer.

“That’s easy, a foal gets their cutie-mark when they learn their ‘special talent’.” Sweetie Belle says knowingly. “Yeah everpony knows that!” Agrees the other two.

“No, I’m talking about a rare type of cutie-mark. I can’t tell you anymore because it might affect the tests. Will you help me?” You ask, eager to begin.

“Sure, the Cutie-Mark-Crusaders are willing to do anything to get their cutie-marks!” The fillies say in unison.

“Great, now let me just go get my supplies.” You say as you go outside to your cart. Celestia it was such an ordeal to get these you think, shuddering as you remember the ordeal you went through yesterday.

********

The sun is shining above as you make your way to Rarity’s Boutique.

“Hopefully Rarity will have what I’m looking for. She and Pinkie Pie are into this stuff according to Rainbow Dash.” You say as you canter down the gravel road. When you reach the store, you are surprised to find it closed. “Huh, usually she’s open at this time of day. Well she won’t mind if I just ‘pop in’, we are friends after all.” You think out loud as you slowly open the door. “Rarity? Are you home?” You ask. You hear giggling and the sounds of laughter and as you walk farther into the shop the noises become more intense, almost as if you were getting closer to the source, or if somepony was intesifying the noises. You go upstairs and trot towards Rarity’s room and open the door and gasp at the sight of Pinkie Pie eating out Rarity. Luna on the moon you think as you continue to watch. Pinkie Pie takes her hoof and begins rubbing Rarity’s clit. They don’t even know that I’m here you think as Rarity begins to cry out.

“Pinkie dear, I think I’m gonna-I’m gonna…AHH!” Rarity says as she reaches climax.

“Yum, that’s better than any sweet I’ve baked!” Pinkie says with a silly smile as she licks the juices dripping down Rarity’s tail and legs. You cough in order to get their attention. Rarity shouts at the sight fo you and then covers her pussy with her tail. Pinkie Pie starts laughing. “How long were you there?” Rarity asks, embarrassed by the current events.

“Enough to know that you really enjoy each other.” You say, giggling. Pinkie Pie runs up to Rarity and gives her a big hug.

“She’s my cuddle monster!” Pinkie Pie says, giving her a kiss. Rarity blushes and then kisses her back. Then they begin getting really into it and start moaning and you have to cough again to remind them of your presence.

“Sorry dear, once I start I tend not to stop,” Rarity says, “OK, so is there a particular reason why you popped by?”

“Yes, I was wondering if you have any binds and rope.” You say

“Oh, yes but I have some dress binds, and I don’t usually carry rope, that’s actually an odd thing for you to ask Twilight dear, but I do have some.” Rarity answers, opening and closing drawers with her magic.

“Uh no, I meant, like, uh, binds for uh…role-play.” You say quietly, getting extremelly embarrassed. Pinkie Pie giggles. “Twilight, I didn’t know you were into bondage, me and Rarity are too! It’s pretty kinky.”

“Well, you see, I’m conducting some experiments and I wanted to try them out and…” You say, trailing off.

“Of course dear, we all do ‘experiments’ it’s perfectly OK for a lady to be interested in fore-play and such. That’s how me and dear Pinkie Pie started dating.” Rarity says, giving you a happy look.

“Uh…yea…” You say, realizing it’s pointless to convince them otherwise.

“Well here, these might work, and I’ve got some ballgags and a whip too, OH this reminds me how excited I felt the first time me and Pinkie Pie started having sex. She would tie me up to a bed, and then she would-“ Rarity starts. You cough again. “Oh yes, sorry, like I said before, once I start I tend not to stop. Here we go then.” She says as she levitates a bag full of different sexual toys.

“OKIE DOKIE LOKIE, well me and Rarity have some ‘things’ we need to do, so if that’s all you need then have fun!” Pinkie Pie says, rushing you out the door.

********

“I’m, back!” You say as you trot back into the library levitating a bag full of ‘toys’ in the air.

“What’s in the bag?” Sweetie Belle asks curiously as you set the bag down on a desk.

“Equipment for our experiment. Now Sweetie Belle and Scootaloo, you’re up first. Apple Bloom, I want you to just watch, and do whatever feels…natural, but don’t interfere with what they’re doing. OK?”

“OK!”

You open the bag and let the contents spill out on the floor. There are binds, a dildo, a ballgag, a whip, and a vibrator. Apple Bloom looks at the dildo questioningly. “Hey, ah’ve seen one of those in my sis’ room, ‘cept it was bigger.” You cough, choking down a laugh.

“So what exactly are we doing and how do we do it?” Sweetie Belle asks.

“Well technically you’ll be having sex with each other, only this is a different way to have sex.” You say, grabbing a scroll and pen.

“Hey, I think I know what to do, I’ve seen Pinkie Pie and Rarity do this before. OK, here Twilight can you levitate the bed down here?” Sweetie Belle asks.

“Sure.” You levitate the bed and place it gently between Sweetie Belle and Scootaloo.

“OK now come here Scoots I’m just gonna tie you up.”

Scootaloo laughs. “No way, this is just too weird!”

“Come on, don’t you trust me? Besides it’ll be fun.”

“OK, but if I tell you to untie me, will you?”

“Of course.” Scootaloo then gets onto the bed and Sweetie Belle then begins to use her magic to wrap the binds around each of Scootaloo’s legs and the other ends against the bedposts. Scootaloo then blushes. “Wait, you can see my-my…” Scootaloo says quietly, slightly embarrassed.

“It’s ok, here, you can see mine too!” Sweetie Belle says as she shows off her cunt to Scootaloo. Scootaloo instantly turns red. “I feel, warm down there, like, like I want to touch it…” Scootaloo says, straining against the binds. “Augh, I NEED TO TOUCH MYSELF!” She yells.

“If you say please, I will for you…” Sweetie Belle says with a kinky smile. You start taking notes furiously. Woah, she must watch her sister a lot because she sure knows what she’s doing you think as Scootaloo nods her head and says ‘please’ to Sweetie Belle, who then begins to slowly rub Scootaloo’s tender lips.

“Sorry if I’m bad at this, I’ve only seen my sister do it with Pinkie Pie a couple of times. You’re really dry down here, let me fix that.” Says Sweetie Belle as she leans down and lightly kisses her lips. She then moves up to Scootaloo’s face and begins to kiss her. Scootaloo happily greets her and kisses back and soon the two are going at it like there’s no tomorrow. You hear noises coming from your right and you turn to look and see, to your surprise, Apple Bloom moaning and rubbing her clit. She stops to lick her hoof and then continues to rub it, occasionally pinching her clit and moaning louder. You turn your attention back to the left and find that Sweetie Belle has already gone and wrapped a ballgag around Scootaloo’s mouth, preventing her from shouting out. Wow, this is going well, but they still haven’t gotten their cutie-marks yet you think as you look at their hips and notice that they’re still blank. You decide to add a little variable by casting a spell to speed things up. You leave the room and go through your library of books until you find a book titled SPELLS FOR SEXUAL ACTIVITIES. You look through the book and find a page entitled PHEROMONES and something else, but it’s too dusty to read. Perfect, this will probably speed things up you think as you read how to cast the spell. You cast the spell and the room begins to fill with pheromones and chemicals and you instantly begin to feel very warm. That’s when you realize it: you’re in heat. You look back at the page and blow on it, revealing that it says PHEREMONES AND HEAT. UH-OH! I didn’t see the whole page. At least foals can’t go into heat you think as you continue to read the page. “OH BUCK ME!” You yell as you read the fine print; WARNING! Casting this spell causes all ponies that inhale it to go into heat, no matter what age. “Well this is going to be interesting…” You say as you hurry back into the other room. You gasp at the sight in front of you: Apple Bloom has taken it upon herself to use the dildo on her asshole. Sweetie Belle has untied Scootaloo and the two are rubbing each other’s clit and cunts against each other. They continue to scissor until Scootaloo cries out.

“I think I’m gonna…I feel like I’m gonna pee!” She yells. Suddenly she goes into a spasm as she has her first intense orgasm.

“It’s called cumming, Scoot’s.” You tell her as you grab the vibrator to satisfy your craving loins. You turn the vibrator on and move it towards your tender lips, listening to the whirring noise it emits. You slowly rub it against your cunt’s lips and gasp, the sensation making you shiver in pleasure. Urgh, I can’t take it! I NEED IT IN ME you think as you slowly move the phallic object inside you. You begin slowly moving it in and out, pumping it to your satisfaction, feeling yourself reach climax. You hear moans and the sounds of the fillies experiencing their own orgasms, but the sounds are muffled by the intensity of your own. You reach down and wipe your juices with your hoof and then bring it up to your face and lick it clean. So yummy, but I need somepony else to help me, It’s no fun by myself you think as you eye Apple Bloom. You then stand up and trot over to her. “Apple Bloom, you need some help over there?” You say seductively as you crawl over to her, placing your hoof on her leg and slowly trailing up her thigh. She moans at the sensation and nods her head.

“Yes, please Twilight, it hurts so bad, ah NEED somepony to help meh!” She says, tearing up slightly as you pull the dildo out of her ass with your magic. She sighs and you take your vibrator and rub it against her vaginal lips, causing her to shiver in delight. “Ah feel so good Twilight. What’s happening? It feels so natural.”

“That’s because it is good and it is natural.” You respond as you begin to kiss her leg, moving up until you reach her ass. You then give it a tentative lick and then continue licking it, the taste unique to you. Apple Bloom then gets up on all fours and licks your horn causing your body to scream in delight. Your horn starts to glow and shoot sparks the more she licks it. Apple Bloom pushes you down, holding all your legs with her own. You struggle to get up but you realize she’s spent her whole filly life working on a farm and your strength doesn’t compare. You begin to panic, but as she forcefully kisses you and shoves her tongue into your mouth, you give in and stop resisting. This form of sex, almost like being raped, but enjoying it and putting your trust in a pony so young is entirely new to you, yet your body and mind enjoy it. She begins to suck on your neck, but you feel apathetic towards it. Not something that I entirely like, but I don’t mind it either you think as you do the same to Apple Bloom. You look behind her and notice that Sweetie Belle and Scootaloo are cuddling with each other, completely wiped out.

“Hey Twilight, bend over, ah want to try something.” Apple Bloom tells you. You obey her and then feel a sharp smack on your backside. You gasp and cry out in joy.

“OH CELESTIA YES! SPANK ME PLEASE!” You shout. Apple Bloom gives you another sharp smack in reply and you cringe in joy. Apple Bloom continues to spank you until it sends you into your second orgasm of the day.

“Hey, get down here with me. I want to hold you.” You tell Apple Bloom as she gets down and huddles against your warm and wet body. You begin licking her pussy until she goes into an orgasm and you both give a sigh of relief.

The next day you awaken to find all three Cutie-Mark-Crusaders staring at you with joy in their eyes.

“WE GOT OUR CUTIE-MARKS!” They all cheer together. You look at their flanks, and, just as they said, they each have their own variety of cutie-marks.

“Let me go to the books and check which cutie-marks you have.” You tell them. You then walk into the other room with the fillies in tow as you levitate the book THE DATABASE OF ALL KNOWN TYPES OF CUTIE-MARKS. “Let’s start off with Sweetie Belle, let me see your cutie-mark.” You say, getting excited. She shows off her newly acquired cutie-mark, which is an orange heart, cut in half with a whip on the side. “Allright Scoot’s, you’re next.” Scootaloo does the same thing, and her cutie-mark is a white heart, cut in half, with a ballgag next to it. “And lastly, Apple Bloom.” Apple Bloom happily shows off her flank, revealing a fully shaped lavender heart.

“Cool huh?” They all ask.

“Yes, but let me read about them now, OK?” You tell them. You open the book and turn to the ‘fetish cutie-mark’ section and then find the ‘heart’ and ‘half heart’ cutie-marks. There’s some fine print here. Let’s read it you think as you read it aloud. “The half heart cutie mark is a symbol of united love, it connects with the other half to make a whole heart and united lovers. The whole heart is a sign of love that will never be complete, for it means that the other half of the cutie-mark is gone, for that other half already has their very own cutie mark separate from the heart. The whole heart will follow the ‘false half’ for the rest of their lives.

“What'd ya say?” Apple Bloom asks, looking at you dreamily. You glance at Sweetie Belle and Scootaloo, but they are already on their way out of your library, leaning on each other, madly in love.

“Hey Twilight, ah wanna be with ya now!” Apple Bloom says, gazing at you dreamily.

“OH BUCK ME!” You say out loud.
