Twilight and Rainbow suddenly appear in your condo and definitely want to learn more about human anatomy.

It's almost a cliche. You're a single brony living in your own apartment. Undone dishes in the kitchen, Plushies laying around, you surely know this too good.

But one day things go a little different as Twilight and Rainbow Dash appear at your home and want to learn more about friendship.

UPDATE February 2017: I know many of you wanted to read the next chapter of this story but unfortunately I never managed to finish the next one. I just don't have the time since I got a new more challenging Job and as I am now in a relationship. Sorry everyone, maybe sometime I will finish it but for now, see it as "Cancelled"

Chapter 1: For The Studies of Friendship

Chapter 1: For The Studies Of Friendship

You did it, you finally did it. You managed to move out and get your own apartment. Your best friend knew someone who rented out the apartment you moved into a few months ago. It was a lot of work to furnish it and you almost ran out of money, but with the help of your family and friends you managed to do it.

Finally, you are able to live the Brony life you always dreamed of. No one makes fun of your plushies standing or lying around. No one cares about the posters on the walls or the wallpaper on your computer desktop showing Rainbow Dash in front of her locker with that bionic wing she got when the real one was, obviously, ripped off in the alternate reality where Sombra ruled Equestria.
Yeah, no one cares about that not your friends and not your girlfriend. Oh right, you don’t have a girlfriend or someone to share your apartment with and that’s the one thing that's missing.

You step out of your car trying not to hit the rusty car in the spot to the left with your door. Today it's rather windy and rainy, that’s why you chose to take the car instead of your bicycle, even though you only live a few minutes from work. You switched jobs a couple of weeks ago. Sure your work is much closer now, the colleagues are a hundred times nicer and way more cooperative, but you still aren’t sure if it’s the right thing for you. The pay is a bit less than before and you have to work way harder for it, to name a few issues.

Deep in thought over what you really want in life, you made your way towards the entrance of your apartment. Gravel and dirt crunches beneath your shoes. The landlord started to add a new apartment to the building at nearly the same time you moved in. Wheelbarrows are standing around outside the building,one far dirtier than the other. A plastic sheet clamped between two bricks flaps in the wind. As you were nearing the entrance to the building you nearly stepped on a bent nail. Picking it up and throwing it into the nearby garbage bin you angrily think of how many of these pointy suckers you found and will find in the future. One of the wheels on your car already suffered a puncture because of them.

Pulling the mail out of the mailbox you pushed open the door, and make your way up to the second floor to your apartment. On the way up you notice that you forgot to close the window beside the stairway before you left for work. Now there's a small puddle of rain on the ground from the showers earlier. You roll your eyes, close the window and continue your journey up to your door. You silently hope water didn't leak into the kitchen through the skylight, again. Unlocking the door and stepping into the apartment you realize once again that it was simply too big for one person alone. You pull off your jacket and hang it on the hook to your left. After slipping out of your wet shoes you close the door behind you and step into the kitchen to your right.
Luckily no water on the floor, "At least that's one good thing today" you sigh. Piles of plates, used drinking glasses, and dirty cutlery decorate the kitchen counter. Opening the drawer, where normally clean and shiny cutlery would be found, you roll your eyes, empty again.

“So we have to do the dishes, great”, you say to yourself.
Nearly maxing out the volume on your stereo, with a mix of the newest Brony Music, Metal and other genres you love, you start to fill the sink with hot water and detergent. Never ever again will you buy a kitchen without a dishwasher you think as you try to scratch off day old ketchup from a plate.

Suddenly you hear a noise, a loud thumping coming from somewhere in your bedroom. To be sure you’re not imagining it you pause the music, there it is again. You quickly dry off your hands with a nearby towel grab a freshly cleaned knife and start sneaking towards the door to your bedroom. Quietly you shuffle out of the kitchen and to the right. Peeking around the corner nothing unusual immediately stands out in your bedroom. You slowly walk into the room looking around expecting to see something or someone. Nothing.
“Hmm, maybe in the wardrobe?”, you think out loud. Holding up the knife for whatever comes next you open the wardrobe. Still nothing. What the hell is going on here? Maybe you’re just getting paranoid. You walk back into the kitchen and finish doing the dishes.

After about half an hour of washing and drying, you are done and decide to have a nice and relaxing bath. You know your muscles will thank you for the hot water and the curing bath salts. You turn on the air heater and the faucet. It doesn’t take long for your bathroom to be filled with hot steamy air and a refreshing smell. You undress and throw the sweaty pieces of clothing in the direction of your washing machine. You slide your hand into the water in the bathtub, Ouch! it’s way too hot.
You turn on the faucet again trying to conquer the unbearably hot temperature with icy cold water. After a few minutes, the temperature is just right and you lift one foot up preparing to get into the tub.

“Is he in there?”, a muffled voice came from god knows where.
“Yeah, he locked himself in this room”, another voice said. Maybe your neighbors have turned up the volume of their TV again. Wait, the neighbors are on their holiday vacation. They gave you the key to their apartment one floor beneath yours and asked you to water their flowers.

A loud sound of something shattering into pieces came through the door. Startled, you slip and fall down onto the white tiles that cover the floor. You moan in pain and rub the back of your head.

“Oh my Celestia, what was that?!”, the first voice asked in a nearly hysterical tone.

Listening closely to the two voices, you are now sure came from the kitchen, you realized that the first voice sounds very similar to a certain purple pony from a certain TV-show half your life revolves around. That can’t be, right?

“Maybe we should just kick the door in, Twi”, a raspy voice worriedly says. Could that voice belong to…
"Rainbow! you can’t just kick somepony's door in. There’s a simple spell for this".
“No, this can’t be. How in the world is this possible? Ponies in our world? and even in my apartment? ”, you think to yourself as a sphere of purple magic begins to wrap around the lock. With a quick “click” the lock turned around and the door flew open. Over the doorstep walking in with eyes wide open, Twilight Sparkle and Rainbow Dash enter your bathroom. You feel like you’re passing out.

“Oh my Celestia, what happened?”, Twilight asks with a worried look.

“Ah… I… Uhm…”, you stammer while you try to collect your thoughts. Suddenly it hits you, you’re still naked and your two favorite ponies are standing right in front of you. They look a bit confused as you quickly turn to the left and try reaching for your clothes laying beside the bathtub.

“Hey, slowly, you're clearly hurt, you shouldn't overwork yourself”, Twilight said .
You are finally able to reach your t-shirt and use it to cover your lower regions.
“Why are you doing that?”, Twilight asks as she reaches out her right hoof towards your crotch and your only piece of clothing, trying to see what you are hiding from her.

“Hey hey hey, what the!”, you shout and slap away Twilight’s hoof.
She flinches back and her eyes grow a little wet, "W... Why did you hit me?", she asked with a sadness in her voice.

"I, um, didn't want to hurt you but you were about to disturb my private sphere.", you try to explain.

"Your private sphere?", Twilight asked with a questioning expression on her face.

“Geez, Twi!” He’s hiding his stallionhood under that shirt”, Rainbow interrupted suddenly while rolling her eyes.

“Oh, ok, now I get it”, Twilight slowly said. “Yeah! I remember now, some of the books in my library show pictures of human anatomy. Can I see it?”, Twilight asked curiously.

“What? No!”, you shout.
Of course, most of your fantasies about making out with a pony were either with Twilight Sparkle or Rainbow Dash or even both. But now that they were standing right in front of you, it seemed a bit rushed to meet a mare and almost instantly get it on with her.

“We don’t know each other, maybe we should get a drink first and have a little talk or something like that?”, you suggest.

“Ok”, Twilight and Rainbow say simultaneously.
They turn around and trot out of your bathroom.
You quickly get up to your feet still feeling a bit of pain in the back of your head. You quickly redress yourself in the clothes you threw aside before.

Stepping out of the bathroom and back into the kitchen you notice that the two ponies aren’t here. They are already sitting on your couch in your living room.
“What can I get you to drink?”, you shout towards the living room while looking into your fridge. You realize that there is only Apple Cider left and remember that you wanted to buy some groceries but forgot, again. You sigh and take 3 bottles out and close the door. Stepping into the living room you hold up the bottles and say, "Sorry, I only have Apple Cider here.”

Twilight grinned slightly, "Are you trying to get us drunk… uh, we don’t even know what your name is.”
“Anon, it’s Anon”, you say and flinch as one of the bottles begins to levitate out of your hand surrounded by an aura of purple magic.
Beside Twilight the blue pegasus’s eyes widened, "Oh my gosh, oh my gosh, oh my gosh, I love Cider!” She flew over to you. Rainbow grabbed the second bottle, hovered back and landed on the couch again. While you reach your free hand out for the bottle opener Twilight had already opened hers with magic. You almost laugh as you see Rainbow Dash holding the bottle between her front hooves biting around the top to get the bottle open. "She looks way too cute doing that", you thought to yourself.
An idea of glass shattering and a heavily hurt pony suddenly forms in your mind. You lunge forward and quickly pull the cider out of Rainbow’s hooves. You open it for her and hand it back, Rainbow greedily takes it and emptied it with a few gulps.
“Whoa,this Cider is delicious”, she said after a few breaths. “Can I have another one?”, she asked.

Standing there and thinking about the ethical implications of getting a pony drunk you don’t move an inch.
“Uh, hello?”, Rainbow said and waved her hooves.
Hmm, she has to know what she's doing, right? So you open the fridge once more and pull another bottle of cider out. You hand the opened bottle over to Rainbow, this time she only takes a sip and sets it down on the table in front of the couch.

“So, why are you two here?”, you ask them sitting yourself between the purple alicorn and the blue pegasus.

“Well, basically the map sent us on a mission”, Twilight explained.

“The map?”, you ask knowing she means the map on the table in her castle.

“Yes, the cutie-mark-map. Every time there’s a mission for one or more of us our cutie marks light up and show us where to go. This time mine and Rainbow’s lead us to Canterlot castle. Celestia opened a portal and told us to travel to your world and gather information about the creatures living here and maybe learn something about friendship too.”

You sit there for a few moments and try to process this information. Slowly you accept the fact that there’s now a portal between Equestria and earth. “Why me? Why not someone else?” you ask.

“We wanted to go to a small town so as not to attract much attention. Since there are only about 1600 humans living here and you’re the only one that we knew had heard of ponies you were the only option Anon.”, Twilight explained further.

Thinking about it that seems pretty reasonable. You notice that Rainbow has gotten way quieter over the last few minutes. You turn your head to the left and see her lying beside you, her eyes half closed. "Something wrong Rainbow?”, you ask.

“Hmm no, jus’ a lil’ drunk,” she murmured.

“What? Why? You only had", you glance over to the table, "One and a half bottles of cider”, you almost laughed.

Twilight shakes her head and says, "Yeah that’s true but the cider Applejack makes has much less alcohol in it.”

“Oh, I’m sorry. I didn’t know”, you apologize.

Rainbow Dash smiled and inched a bit closer to you and rests her head on your lap. “I’m so sleepy”, she murmurs, opening her mouth and yawning.
“Maybe we should all go to bed for today”, Twilight suggested.
You ask the two ponies if they have a place to stay tonight or if they needed to stay here.

"It would be great if we could stay here for a while”, Twilight answered

You smiled and grab some blankets from under the TV board. Tossing them over to Twilight and Rainbow , ”Here! if you’re cold tonight there are more under here”, you point towards the TV board.
“Ok, thank you Anon”, Twilight says and smiled. Rainbow seems like she wants to sleep without any covers at all. You walk over to her and cover her with a blanket. After stuffing it under her warm body so she doesn't freeze during the night. You just couldn’t resist caressing her ear, softly and slowly brushing your fingers through her Rainbow coloured mane. A soft smile grew on her face and a short hum escaped her mouth.

Something in the corner of your eyes gets your attention. You turn to your left and notice Twilight sitting directly beside you, watching what you are doing. Quickly pulling back your hand you stammer, “I, uhm… that wasn’t…”

“Can you do that to me too?”, Twilight suddenly asked and blushes.

You stay there and stare at the purple pony in front of you. “A… Are you serious?”, you ask her and she nods and smiles. You sit down next to Twilight and slowly reach a hand out to her face.

“Don’t worry, I won’t bite Anon”, she chuckled.

You begin to softly caress her left ear with your right hand. She closes her eyes and buries her face into your palm. Her fur feels as soft as Rainbow’s. “Mmmmmmhh, that… that’s amazing”, she sighed. Twilight tilts her head back and you begin to ruffle the fur right below her chin.
She hums and lets herself totally melt into your touch. Maybe she’s enjoying this a little too much?

After a few minutes she opens her eyes and shakes her head to get her thoughts straight again, "Maybe we should go to sleep now~”, she says. You nod and slowly try to get up from the couch.

“No… I mean could you sleep… here… here with us?”, Twilight asked and blushed. She looks so cute like that you thought.

“Yeah, sure… I mean if you want me to”, you answer. Not really thinking about how awkward it will be to sleep on the same couch as two ponies you often fantasize about. You grab a blanket and lie down. Twilight crawls up to you and looks at you with a nervous expression. You roll to the side and put an arm around her. You feel her warm body pressing against yours. You can feel her hot breath on your lips as she faces you with half lidded eyes. “You know Anon, I've never met a human like you before. I never thought you would be so kind, and those things you have instead of hooves feel amazing.”

You brush two fingers over her cheek. She closes her eyes for a second and opens them just to look at you with those beautiful eyes.

“I know we just met and this whole thing is a little awkward” -she moved even closer to you- “but I really want to learn more about humans. Every detail, every… touch.”

Her lips touch yours and she kisses you. At first you two stay completely motionless, your lips locked in a simple embrace, then you slowly push your tongue forward. She opens her mouth slightly and your tongues meet each other half-way. Her breaths get heavier and shorter as the two of you kiss more and more passionately over time.

Quiet moans begin to escape her throat only muffled by the sounds of your own. You tighten your grip around her and pull Twilight even closer to you. Warmth begins to emit from her soft body. You feel a hoof wandering down your spine and trying to pull off your shirt. Loosening your grip around Twilight and breaking the kiss with a wet smack you strip off your shirt. At the same time Twilight was undoing your belt and pulls down your jeans with her magic.

Her left hoof circles a small area dangerously close to your manhood. She pushes her upper body even closer to you and whispers barely audibly into your right ear,"Just for friendship studies."
Her lips once more connect with yours and she let out a short and quiet moan,"Mmmm."
Your saliva mixes with hers as your tongues fight for dominance of her mouth. Your right hand is now on her back slowly caressing the spot between her wings. You run two fingers down one of them and slightly squeeze a single feather between your thumb and index finger. She breaks the kiss and throws back her head barely managing to stifle a moan so as not to wake Rainbow sleeping on the other side of the couch.

"I'm sorry, I didn't know that wings were so sensitive", you apologize in a very low voice.

"No... Nothing to... ah... apologize for.", she pants and presses her lips against yours once more, far more aggressively than before and her breath gets heavier every second. You wrap your arms around Twilight slowly caressing her wing joints again.

Suddenly you feel a warmth surrounding your right hand and feel it being pulled downwards, right towards her flanks and further down between her thighs. The heat her body emits gets hotter the closer she pulls your hand towards her love. You feel her burning lips drenching the tips of your fingers. The strange feeling around your hand disappears and you're finally able to move it of your own accord. You gently start to circle her quivering pussy. Her breath quickens a bit and the frequency of her moans rises noticeably. You feel Twilight begin to slowly stimulate your member. Her left hoof is rubbing up and down on the bulge in your underwear. Her hoof glides under the waistband of your boxers and slides them down. The tip of your fully erect member pokes out and Twilight touches it gently. She pushes away from you just enough for her to look down at your throbbing shaft.

“I’ve never seen a human’s before, it looks completely different than any stallions”, -she touches it once more and your dick twitches slightly-, “But it certainly fills the same purpose” she breathes heavily into your ear.

She uses her magic to pull your boxers off completely while she begins to slowly stroke it with her right hoof. The texture of her fur sends jolts of pleasure right through your cock and up your spine. She moves her body closer to you still massaging your dick from base to tip. Looking at you with half lidded eyes and intense need she brings her muzzle up to your ear and whispers, "P... Please, please make me... ah make me cum Anon.", she begs.
You place a soft kiss on her muzzle and begin to increase the rhythm of your strokes to her pussy. Twilight buries her head in your chest in an attempt to muffle her moans and not wake up Rainbow Dash.

The smell of her mane reaches your nose and you lower your head to get more of that sweet, intoxicating smell. You softly nibble on the tip of her left ear which makes her squeal softly. The amount of juices gushing out of her dripping cunny increase with every stroke. You decide to go a step further and gently push one finger inside her sweltering hole. She presses her head even harder against your chest. It almost hurts but you don't care. All you care about is Twilight and her special way of studying.

You slip a second finger inside her. You feel the heat that radiates from her lower body. She is obviously having trouble keeping her moans quiet now. She squeaks every time you slide your fingers in and out of her. You feel her inner walls twitch and the amount of liquid pouring out of her increases with every minute. Suddenly Twilight makes an unexpected movement. She wraps her magic around you and manages to pull you on top of her.

She brought her head back up to your face and kisses you. The hand that was pleasuring her was caught between the couch fabric and Twilight. You pull it out and wrap both your arms around her fuzzy body. You feel hot air coming out of her nostrils on your face. Her tongue is fighting with yours and saliva mixes while the two of you are kissing. Your cock is being sandwiched between the two of you and you feel the texture of her fur over the full length of your member. Every time she moves under you one of her nipples rubs against your shaft and she moans.

After a few minutes, she breaks the kiss and leaves a thick strand of saliva connecting your tongues. It breaks and falls down on Twilights chest where it shimmers in the moonlight shining through the window. She looks at you with pure lust and need in her eyes. Her face nears yours once more and she whispers, “Please… put it in. I can’t bear it anymore.”

“But Twilight”, -you whisper back slyly- ,”Didn't you say this was all just for study purposes?”.
“Yeah… it was… at first, but I feel something every time you touch me. There’s more than the urge to study you and your body. It’s just-”

You nuzzle her and give her a quick kiss on her nose. She wiggles her rump and lines up her dripping wet marehood with your rock hard cock. The tip of your member touches her entrance and she gasps loudly. You two remain completely still attempting to hear if Rainbow is still asleep. The sky-blue pegasus mumbles something inaudible and wraps herself tighter in the blanket you put around her earlier. You turn your head back and look at Twilight. She gives you a warm smile and nods. You lower your head and kiss her. Then you start to push forward. A moan escapes her throat and is muffled in your mouth as you push further into her hot tight honey pot.
You feel her inner walls twitching and clenching around your cock as you push further into her. After you fully bottomed out you wait a few seconds for Twilight to calm down a bit then start to pull out halfway before slowly pushing back into her. Her breath quickens the moment you begin to slide in again. She lets out short definitely audible moans. But neither of you care anymore. The only thing that’s important to you is Twilight lying below you and the fact that you’re fucking the cutest librarian in Equestria. You speed up your pace and wet smacking noises begin to fill the room as you continue to piston in and out, slamming into her pussy. Twilight’s breath got heavier with each thrust as you also feel both of your climaxes approaching but you force yourself to keep up your rhythm.

Suddenly her wings spread out and she wraps them around you to pull you as close to her as possible. Her hips begin to buck in rhythm with yours making every thrust impact even deeper. Her ears fold back and with one final thrust you drive Twilight over the edge. Her inner walls contract and try to pull your dick further inside her. The feeling of her walls pulsating and the liquids running out of her almost makes you go crazy. Twilight let out a cute whimper, “Ahnn!”, and this finally drove you over the edge. Hot semen spurts out of your member filling up Twilight. Each spurt sending a wave of pleasure through your body. Twilight’s horn begins to glow slightly every time you shoot another load of your white cream inside her the light pulsates a bit.

After an incredible orgasm you break the kiss with Twilight and let yourself roll down of her and lay beside her. Your cock slides out of her vagina and some of her juices mixed with semen drip out and onto the couch where it slowly seeps into the fabric. Twilight pants and turns around to you, her hoof slowly drawing circles on your sweat covered chest, “That was way more than I would have needed for my studies. But I don’t think Princess Celestia needs to know about our little extra lesson.”, she pants and smiles at you.

Twilight lays her head on your chest and magically levitates the blanket, that had been knocked onto the floor by your lovemaking, over the two of you. You plant one last kiss on her head before you close your eyes and drift off to sleep.
