The Experiment

It's been a long year since you have arrived in Equestria. Ever since that day, you have had to come to terms with; can never return to Earth, the inhabitants of the planet are either animals or mythical creatures back home, That half of the ponies (I.e nobles and the like) think your nothing but an animal, and the biggest is that you deeply love Luna. You have been in a relationship with Luna for 4 perfect months. And the crazy attempts, you tried to woo the princess of the night with, make you chuckle, and hide in embarrassment. But would you do it again, to win her heart? You wouldn't even need a second to think about it, the answer is yes. Like every relationship there are ups and downs, especially if your other has wings. Your first fight, involved none other than the princess of assholes Blueblood. Luna wasn't happy that you punched him and knocked him out in one go, even if it was in self defence. Although she would never admit that if he didn't do it, she would have, and was a little jealous.

One of you most favourite moments with her that wasn't sexual in any way, was when the both of you pranked Celestia in her day court. Lets just say pink hair dyes are banned from ever being sold in Canterlot ever again, and Celestia can't look at a cake without thinking in someway that it's a trap. How ever your favourite moment ever with her was obviously sexual event. But it wasn't the first time you did it, because the first time was kind of awkward and you two were getting used to each other. No the best was when you two went at it literally all night an into midday the next day. You poor genitals needed 2 days rest, with them being so sore (yours and hers).

You have a decent size penis, but compared to ponies. They don't say "hung like a horse" for no reason. However a powerful spell from Luna and your just as big as any normal stallion, permanently (Well only when erect, otherwise that would just be awkward). Although she won't admit it, but you can tell, she prefers you this way. And that doesn't bother you, what ever makes her happy, and truth be told, you were a little bit jealous of stallions and a tiny bit self-conscious. And it's not a well kept secret that horses or ponies love sugar and salt, a lot more than humans do. Then also add the fact that you sweat and ejaculate one of those. Lets just say if word got out, you wouldn't be left alone by some ponies.

However you have got something big planned this evening, little did you know so did Luna.

"Why don't you put that journal down, and come on pleasure thy princess" Luna says in the most sexual and alluring voice she can muster.

Nodding you put the quill down, and slowly walk over to the bed, holding your mare. You waste no time and take Luna into a deep passionate kiss. Luna is slightly taken back by your assertiveness tonight, but welcomes it none the less. And moans into your mouth. And so the battle of the tongues begins, the winner will have bragging rights and the losers will not. Although nether of you can lose in a sense, but you two have grown quiet competitive. But Luna has evolution on here side. What with have a bigger and more power tongue, and bigger mouth and that Alicorns are much stronger than humans. Although humans are in-between pegasi and unicorns for strength, well at least they would be if they have magic in them like you do now. Anon finds it cool that ever since the planet changed his being, and made him able to use magic (not directly, but indirectly, like pegasi with their wings and earth ponies and their strength and so on), his stamina has greatly increased, so has his strength. But something he wasn't expecting is that, when he plays some kind of instrument or is signing he can effect others around him a lot more than ponies can. He is not a great singer by any stretch of the imagination but, it's the feeling behind that words. He can't control anyone, far from it, he can just effect what mood they are in.

After a great long battle, Luna comes out on top, which Anon has no problem with. "Huzah! We win that little battle. Thee know what that means....." Luna is now giving you a vil smile. "We get to decide where this goes tonight." She moves her legs over to the other size of you, and is now looking down at you from above. Her hair is following as always, but with the moonlight hitting it perfectly, it only adds to her beauty. "My my, my human. Is something in your pocket or are you just happy to see us." And with that she adds pressure to the intruder of her personal space.

This only gets a moan from you. You now human enhanced penis is almost at full attention, and with you jeans still being on, it's defiantly not that comfortable anymore. Using her magic, Luna takes of your belt, and undoes the buttons in your jeans. With a little more room to breath, your love stick comes straight out, but still with the confines of your boxes. The end of the box is a little wet stain.

Smiling, Luna looks down at your going manhood. "My aint we excited" Luna says chuckling.

"You have no idea. But can you blame me, I have the hostest mare on the planet seducing me."

"Who? little old me?" Luna says playing innocent. Not wanting to be out played, you reach down and put a finger on her other lips. Instantly getting the reward of her squirming and moaning to your touch.

"And you said I was excited......" You don't get to Finnish your taunting as Luna dives straight shouting "MINE!" in a primal way.

The next thing you know, your clothes are off, and you manhood is at the entrance of her marehood. "This is for writing your damn journal inside of having all your attention on me!" And with that, she slams down her rear, taking all that you have to offer. She slams down with a loud slap reverberating around the room. You immediately sit up straight in both pain and pleasure.

You can feel her walls around you, her warmth, and boy is she tight. Luna stays there for a while, before taking you into another deep kiss. With evolves into a make out session. And she starts up again, in the middle of your make out session, making the both of you moan into each other mouths. Slap slap slap slap slap slap. Is what someone would hear the other side of the door, that and the moans of the princess and the human.

How to describe having sex with not only a princess but an Alicorn goddess to most ponies. You have always been a butt guy, not that you can ignore boobs either. But Luna's rear, put to shame most beings you have ever and will ever meet. Although Celestia's is more..... "attractive", which you can't resist a look now and then, I mean come on, your a guy you can't help it. In your eyes Luna's is better. It has the perfect balance of firm and softness, and then add the fact it is big. Not in the sense of fat, but big in the sense of "Daaaammmnn". Also not forget that Luna as an Alicorn can move faster, harder and be more agile than most beings in the universe, never mind other humans or ponies.

Luna picks up the pace, the now space out slap of your bodies slamming into each other, is now shorter. "Ohhhh .............. yessss! Rutt your princess big juicy butt" Not wanting to disappoint, you help by thrusting into her as well. This only increases yours and hers pleasure. It doesn't take long before the pace of it all is at is maximum. Luna is shouting out in pleasure, with you moaning underneath her. You both forget everything around you, and its all about the pleasure.

With how pleasured able and fast this is going, you can't even take your mind off it and say your getting close. With one last thrust, you put your arms and her shoulders and hold her down. Taking in all you have, this sets of her climax, squeezing your love rod even more. And not long after, you join her. Pumping your seed into her. Her vagina milks you for everything you have. Once the torrents of sperm spot, you both land next each to other, in sweat. Panting like dogs on a hot summer day.

"Woooowww" Is all both you can say at this point. After a few minutes of resting, you look toward your partner. Who is getting her great back, but has a very satisfied smile on her face. She looks to you with the same smile "You up for round 2?"

Nodding vigorously, she chuckles, as you go to start it over again. But she stops you with her hand. "I have something different in mind." With that her horn starts to glow...... and so does her crouch. Puzzled, you wait and see what happens. To your shock and fully equipped pony cock appears.

"erm..... Luna? You do know I don't go that way right?"

"Yes.... Im fully aware. What I had in mind is different. You see Anon before my banishment, ponies from all over Equestria offered them selfs to me and our sister. Wether it be for sex or for......... a meal."

She lets that sink in. "A-a-a me-meal?" You eventually say. Luna nods her head and carries on.

"The ponies themselves would be fine after our bodies were done with them of course. Its just that.......... Just that I kinda of.... miss it. Back then, ponies weren't scared of us, and we felt truly loved. Now you can say no, but please hear us out. No harm will come to thee, and before you say, We would never hurt you. We love the too much. This is just away too....... experiment and bring a closer bond between us."

"I-I don't know what to think Luna. You sure its safe?" Luna nods. "Its just a lot to take in you know. And besides you said meal, so why do you need that?" Anon says pointing to Luna's recently formed bobby part.

"Well...... We did used to eat ponies the normal way, but...... Ok here goes. Celestia and I have always had one of these, every Alicorn has one. Why do you think there are only female Alicorn's. There isn't a need for male Alicorns. But male Alicorns can happen though, they are just very very very very rare. Or used to be when Alicorns were more numerous. And yes I had mine, since you came here, Ive just used a spell to hide it. Infact Twilight has one now, the spell used to hide it, is one of the first ones Celestia taught her how to use when she became an Alicorn. But Im getting off topic. We could as I said eat ponies normally or we could.... uses them as a meal in a different way. We could used them in our wombs or ... excuse my rudeness, but stuff them up our royal butts. But my personal favourite was always this way. It just more pleasured for me, and the pony always last longer. And the releasing of the pony, oh my solaris the release! Is so much better."

"Soooo I wouldn't be any harm and would you want this to be a one time thing or....." Anon leaves it out there for her to answer

"Well... If you go threw with this and like it, Im not going to say no. But please for me, just try it once, and it you don't like it, we will never ask thee again." Luna gives you her best puppy dogs eyes, with the complete shaking bottom lip.

"Luna you know thats not fair..... How can I say no to that face."

Luna brightens up immediately and gives you a bear hug, to end all bear hugs. "LUNA....... CAN"T....... BREATHE...... NEED...... AIR!"

"Oops... sorry hehehe" Luna lets you go and smiles sheepishly.

After getting what air you can into you lungs and calming down, you turn back to Luna. "I didn't say yes.... But what will happen if I do say yes?"

For a brief second there are two emotions on her face happiness and sadness. "Well,.... to put it bluntly. You would be turned into cum, I release, then your body will reform."

You sigh. "If you think we should try it then...... I will do this ONCE! And you promise you won't ask again." Luna nods so much, you think she might take her own head off. "Soooo.... How do we do this?"

"Well depends which way you want to go, head or feet first?"

"Erm............. I think head first." Luna nods with a smile.

"Okay my love. I'm pretty excited about this, as you can probably tell. So lets get straight to it." Luna grabs your hands in her magic and rubs your fingers on her second head, in a circular motion. The heads starts to get wider and little by little starts to open up. You are a little bit freaked out, but you trust Luna with your life. Once is open to the size of where you can put one finger in, she forces your hands together and stuffs them inside the head. She instantly moans out in pleasure. Her horn stops glowing and you wondering whats she doing, but you get an answer straight away. You can feel her muslces pulling you into her cock. Your hands slowly descend her shaft. It's not long before they leave the shaft and enter the flesh purse bellow the cock. It's a strange sensation for sure, and you can see them in her balls. Her balls where big, but even ponies, are not as big as both your hands. It looks like you have some skin made gloves on your hands. But the main thing you are wonderings, is you should be in pain, your hands are bent towards you. Maybe Luna cast a spell on you? You think to yourself, Luna is unfortunately too out of it to answer your question. Slowly but surely you elbows where next, and now your head is touching Luna's cock. And fear starts to creep into your mind.

"L-L-Luna I don't think I can do this, I...."

Luna doesn't give you the chance to finish your sentence, as she grabs your head in her magic and shoves it down her cock. All you can do is give out a muffled scream. Her cock is so tight around your face, it's not to uncomfortable, but not exactly 5 star. However your to busy panicking to notice. As your head travels deeper, you shoulders are next on the agenda. Show how, the cock takes them in, like the rest of you, without even stopping. Your head is now entering the ball sack, and from the outside world, your expression is there for all to see, pure panic. But with the sack offering not space what so ever, all you can do its scream in your throat. With comes out as nothing more than a muffled moan like scream.

"Luna, why are you doing this, I didn't want to go through with it." Is all you can think to your self. You start to fell your arms are being force to your sides. As Luna takes more and more of you into her cock, she is getting more and more pleasure from it. Soon your chest is in her cock, and only your lower half is left. But her muscles stop with their pulling suddenly and your descent stops. You feel Luna turning your body around, then she lick your fully erect cock. Getting a loud "Eep" from with her sack. Which makes her giggle.

"Sorry Anon, but once the process has starts, it can't stop...... Now why don't I give you a going away present hmm?" Somehow how you can hear here perfectly fine. But before you can protest in anyway, Luna starts sucking you off. You have to admit is warm in her sack, and the sack itself is very soft. And with Luna give you a blow job, you can't say you are not enjoying it at this moment in time. Luna increases her speed of her head bobbing up and down your cock, and then puts a hoof on your balls and starts rubbing them, making it more pleasurable for you. You feel your balls tightening and an urge to release increases, you try and hold it back, so you can have more of this feeling. But it is going to happening. Luna feels your cock twitch and takes you all in, waiting at the base of your cock. Not long after, you release load after load. And being that ponies love salt, Luna greedily swallows everything you have to give. Once it stops, she sucks your cock hard, milking all that was left in your cock. With that now done, she lets your cock slip out of her mouth, and gives off a loud burp. "Ive always loved how your cum taste Anon. But lets get this over and done with hmm?" And with that the muscles in her cock start again, and your descent beings.

Its not long before you cock enters hers, and its quiet painful and enjoyable at the same time. You chest is now joining the rest of you, as more and more is swallowed. Only your legs and feet are left now. As they kick wildly, trying to get a hold of something to stop your descent. But they prove to be nothing more than worthless at this point. As your feet are the only thing outside now. Luna has a devilish smile and her face, as she tickles your feet. You squirm and shout out in laughter, making it all the more pleasurable for Luna as you struggle, inside her sack. Which is now bouncing on the bed.

Luna gives you a break, and takes the last of you in her cock, as the giant muscles closes around your feet. Luna is now coming down from the high as your feet travel down her shaft and finally with a muffled splash, joins the rest of you. You are forced somewhat into a hugging your legs kind of position. But with the stretches of Luna's sack, it's not to overpowering. And to the outside world, the can clearly see most of your body in high detail. Now that all of you is inside, its kind of nice, but you can but think of something you should off asked before agreeing to this.

"Mmmmmm that was better than it used to be Anon. Maybe its because you're a lot bigger than normal ponies or because of the bond we share. But now that you are 'sacked' as it were. I think I'm going to take a nap."

"MMhmmm mhmm" Is all Luna can her from her crouch. Sighing in bliss, Luna sits up and moves her head closure to you. "what was that my love?"

"Mmmhmmm mmhmm mhm mhmm (How long is this going to take?)"

"Errr..... Lets see, someone your size... Also add the fact Ive not done this in over a 1000 years...... I would say about........ 1? 2? Yeah 2 weeks."

"MMMHMM?!! MMHMM!!" You are cut off by a loud gurgle

"Now now Anon. Its rude to use that in front of a Princess. But then again, in this case 'IN' a princess" Luna chuckles to herself. "Well, night Anon, see you in 2 weeks" It doesn't take long for her to dose off. Leave you to struggle and shift within her sack.
