Matt wakes up and looks around groggily at his environs thinking to himself, what just happened. It appears that he was in a stable and was naked on his hands in genu with his shaft hanging down from him. He looks to his right and see his twin sis ally in the same position. This was the first time he had seen her defenseless in awhile and she was hot with her b cup knocker hanging down. The room is colored with many empty stalls around. Then the room access to the stable open up and sunlight rising tide the room making Matt have to squint his eyes to see what is happening. The doors closes quickly and he can clearly see a man walking into the room with a big bag. He walks over to his twin sister and him and puts the bag on the terrace and starts to babble to them.

'' I bet you are wondering why you are here '', he says.

His Sister and him don't respond.

'' You are here because we are doing an experimentation and you were chosen because of some certain qualities… ''

'' But we are only 16 '', Matt pleads.

The man continues, `` This experimentation will pain, I will differentiate you that, but when it is over we will experience created something miraculous. ``

He then walks over to Matt and says, `` We will set forth with you. ``

Then he opens his bag and takes out some lubricant and an assortment of dildos. He puts on a baseball glove and sticks his fingerbreadth into the lube.

lustrelessness can see what he is doing and begin to resist but his voice is cut brusk when he forcefully sticks two of his finger's breadth into his ass. The feeling is weird. It is afflictive and enjoyable at the same time. It is all over quickly though as he retracts his two finger covered in lube and paseo over and takes a 6 inch dildo and walks over and places the tip on mat 's ass.

'' If you are going to handle what happens succeeding, we are going to involve to loosen you up first '', the man says.

He pushes the dildo slowly into his ass before finally bottoming out. The same feeling comes over him as Matt can feel the dildo inside of him. He then takes it back a few inches and starts to hurl it back and Forth River creating a rhythm. Matt grunts from exertion as he is doing this. Then something really weird happens, he starts to get a boo-boo. He had never been gay in his life story so he thinks that it is odd that he gets a blooper.

The man then says as he is ramming the dildo into his ass, `` Oh so you like this '', while still ramming the dildo into his ass. He then goes back to his bag and takes out an 8 inch dildo and does the same thing. The 8 in dildo makes mat feels fuller then the 6 inch dildo. As he is ramming the dildo in he can begin to feel his ass getting unaffixed and looser.

After about five min of the man ramming the dildo in his ass the man says to him, `` You are almost ready, there is just one to a greater extent thing I have to do to you to get you ready for the master upshot, I have to scavenge you from the inside out. ``


He then goes over to his bag and takes out a tube attached to a big water bag. He goes over to a hosiery on the wall and fills the water bag wide of weewee. The bag must have been big enough to hold a gallon. Then he takes the bag and hangs it on a hook above him that Matt had not noticed before. Matt think he recognizes the bag from some of the smut he watched. It was an clyster, he thought to himself. He then takes the tube and proceeds to flummox it right into his already loosened ass.

'' I am going to need you to be really light in there if my experiment is going to work '', the man says.
He then turns a valve and the piss starts to fall into his ass. matt can find the cold water supply current into his ass making it expand. After a minute he can finger his belly set forth to expand and he looks back and his belly looks like he is significant. Finally the man closes the valve and slowly starts to take the clyster tube out of his ass. As soon as he does this, some brownish unstable shoots out of his ass and onto the storey. It feels really eldritch having the liquid shoot out of mat 's ass. He then proceeds to put the enema tube back in

Matt 's ass and does 3 times before the fluid that comes out of his ass is clear.

The man then pulls out walky-talky and says into it, `` He is set up, bring him in. ``

lustrelessness turns around and sees the doors to the barn open air and a man walks in directing a stallion behind him. `` Oh no '', Matt thinks to himself, `` this ca n't be. ``

The man then walks over to the stallion and starts to rub it cock. Before long a 2 groundwork long cock springs out from the horse.

matt says to the man, `` There is no way that this horses cock will fit in my ass. ``

'' fountainhead it has to '', the man says.

The man then presses a button on his remote and the shoulder strap holding his hands and stage to the soil tighten and he is lifted up into the air on a platform that he was on that he had not noticed before. The platform stops at the perfect altitude for the sawhorse to riddle his ass. The entire then rears up and places both its hooves on a bar so that the hooves will not be on matte. Then the stallion starts to force searching for his hole. flatness starts to set himself for the inevitable. Finally after four or five lose thrusts, the Equus caballus finds his mess. At first the horse cavalry can only fit the apple sized tip of his dick into his ass. The horse then begins to stuff his cock further and further into his ass. Finally, after a couple of minutes of the horse going deeper and deeper into his ass the horse cavalry bottoms out and stands still for a dyad of second. The pain is excruciating. matt almost blacks out from having the horse dick so far up his ass. Then the horse pulls out six inches and thrusts. He repeats this natural action and then forms a invariant rhythm. The pain begins to lessen and the pleasure kicks in. Before long he can feel his own dick start to shoot off on the floor. Then after ten minutes of straight fucking from the horse, he can feel the buck 's balls tense up. The horse then bottoms out and his dick erupts with cum. The hot fluid feels so good inside his virgin ass. The roach of cum cover the inside of his ass and begins to make his ass expand. The knight keeps cumming for about a minute. Finally the Equus caballus stops and rightfulness as the horse pulls its dick out of him the man puts a but plug in.

'' Now we don't need to waste any of that cum do we '', the man says.



He then lowers the political program and takes the straps off Matt 's legs and hands and he collapses on the ground. He feels so bloated and he looks at his abdomen and it looks like he is pregnant from all the cum inside of him. He can feel it swishing around in his ass and it feels variety of good. Then he passes out on the floor….

Matt wakes up on the cold primer naked and looks at himself. His stomach bulged with all the cum interior of him and his ass ached and lustrelessness try to stand up up but can not. He looks around and saw that he is in a horse cavalry stable. He then turns and looks at his twin baby lying next to him raw. She too had a tummy that bulged like she was meaning too but she still looked sexy. Matt could see her B-cup tit because she was lying on her back and her beautiful pussy with just a little tussock of hair at the top of her puss. His hammer starts to farm but at that like moment she woke up.

'' What happened '', proclaims Ally.

'' I don't know, says lustrelessness, `` we were going to summer clique and then… ''

lusterlessness looks over at ally and says, `` Did the horse… ''

'' Fuck my twat, says ally, `` Yeah ''

lusterlessness then hears the doors to the barn capable and eyes the man as he walks into their stable.

'' Rise and shine boys and daughter '', the man says, `` I bet you have been wondering what the experiment I
preformed on you was for. I didn't want to tell you yesterday to spoil the surprisal but here we go. Those 2 horses yesterday that you had a trivial fun with, were normal. I genetically modified you and you sister to get impregnated by any animal. I also modified the time the pregnancy will take to make it go from 9 calendar month to 1 calendar month so you will feel variety pretty soon. Another thing is that the reason I plugged up your holes from letting the cum seep out was because the creatures cum takes about 4 time of day to impregnate you. The rationality I wanted to do this was because I wanted to create the greatest horse ever. I could not do this with mating 2 horses together but I had to mate a horse with a homo because with a human being, the cavalry can be very intelligent. The reason I picked you 2 was because you both have eminent IQ 's, are athletic and it looked like you could manage this. And I thought it would be fun to consume a blood brother and sister. Oh, and by the way, my name is Dr. Jekyll Any questions ? ``

Matt speaks up, `` You can not be dangerous, there is no way that I can be… pregnant. ``

'' Oh, I am quite serious '', Dr. Jekyll says, `` I have given you, ah I don't want to get into specific. Any to a greater extent doubtfulness ? ``

'' Yeah '', Ally says, `` How will the foal come out of our… ''

'' Well your bodies will be changing to accommodate the foals but it will still hurt very much '', Dr. Jekyll
says, '' It will probably suffer to a greater extent than a normal pregnancy so be prepared. You will stay put here in this stable for the remnant of this maternity. Oh, and one more thing. ``

Dr. Jekyll then walks over to flatness and pulls out the but plug holding all the horses cum inside of him. The cum shoots out of his ass and all over the concrete flooring of the unchanging. He then pulls the nag out of
ally and says, `` Well I hope that this semen did its thing. ''

He then walks out of the stable leaving Matt and Ally laying in piles of cum. They both sighed out of
rilievo when the cum was finally out of their pussies and nooky.

'' What are we going to do now '', exclaims Ally.

'' I don't know '', says Matt.

lustrelessness then lays on the terra firma in his puddle of cum, thinking about the events that happened yesterday. Then the man walks into the stable and says, `` Here 's dinner. ``

Then he walks out of the room. flatness crawls over and gets the 2 bucket and brings them over to Ally.
Ally gives Matt a puzzled smell and he just shrugs it off. He then takes a handful of the caryopsis and puts chuck it. `` It 's not that bad '', says Matt.

'' Yeah right-hand '', says ally

She then tries the grain and agrees with mat. They could have probably eaten anything at the moment.
They had not eaten anything in awhile and they were both very hungry. They then took turning sipping pee from the bucket until the bucket was drained. They then fall asleep on the low temperature concrete.

flatness wakes up first the next daybreak and feels different. He feels a weightiness on his chest and looks down and sees that he has some A-Cup pap. His hip had widened too and his stomach was a niggling bloated. His ass also did not find sore anymore. He looks over and sees his Sister awake as well. He could see that she also had alteration. Her hips had widened and her titty went from an A to a B-cup. He then hears a titter ejaculate from his sister.

'' What 's so funny '', Matt says to Ally.

'' Nothing '', friend says, `` That was quite the experience we had yesterday. ``

'' Yeah '', flatness says, `` It hurt at maiden but after awhile it felt really near. ``

'' Yeah '', ally says, `` The horse big dick felt so practiced in my pussy. The best role was when he cummed, it
was so great that it gave me the best orgasm I had ever had. ''

'' Are those tangible ? '' Ally says pointing to her crony tits.

'' Yeah, unfortunately they are. I think that this is one of the side issue. '' Matt says, `` Feel them if you do not believe me. ''

She then walks over to Matt and places her hands on his tits. matte was shaking in anticipation for this and lets out a small moan as she places her hands on his nipple and starts to find around. ally then said to him, `` You can feel my tits if you want. ``

lusterlessness then places his hands on his sisters B-Cup breast. Ally too lets out a small moan as he does this. ally 's tits felt so honest in his work force. He had always admired them and now he was doing the thing he had only dreamt of doing. Her pap were the everlasting size and they were still firm. matt then wanted to engage it a little further. He takes one hand off her tit and started to go it down her body. He reaches her clitoris and starts to rub it.

Her consistency shook violently as the climax went through her unanimous body. After the sexual climax was over, she said to her brother, `` Now your turn. ``

She then grabbed his already hard tool and put it into her mouthpiece. She started to suck his hammer and massaging his balls at the same time. matt could feel his sister sucking on his cock, licking the tip every once in awhile. Then he could experience his musket ball tense up and he said to ally, I am going to cum. '' lustrelessness could then feel Ally depart to deep throat his prick. matt then erupted with cum and then germinate it all down his sisters throat.

Matt then took his pecker out of his sis pharynx and picked her up and laid her in a nook on the hay. He then took his 8 inch cock and directed it into her awaiting pussy. He pushed in slowly not wanting to hurt his sister. Finally after a little of pushing, he could sense his orchis rub up against her ass.

'' Are you ready '', asks Matt.

'' Give it to me '', replies Ally.

lustrelessness then pulls out and slam into his sister. He then started a rhythm and he could sense the precum dripping out. His cock tactile property so good with his babe pussy enveloping it. After what seems like an timelessness, Matt can find his balls tense up and he goes hilt rich and cums into his sister as hard as he can.

They both lay there for a few moments with Matt 's pecker still in his sis pussy and that 's when they heard someone clapping.

Dr. Jekyll had been watching the whole thing and was astonished. He had never thought that this would happen. He then said, `` Bravo you two. That was quite the show. ''

Matt and Ally both blushed as they both thought about what just happened. What made it even worse was that someone had seen them do it. flatness then pulled his semi hard tool out of his sisters pussy and a little stream of cum followed after that.

After a few awkward seconds, the Dr. Jekyll says, `` Well the reason I came here was because I needed to feed your kids '', pointing towards there bulging stomachs, `` The best way to do that is by the semen from their sire. ``

He then leads the two of them out of a stall and into another carrell where both their horses were kept.
The black one was friend 's and the chocolate-brown one was matte 's. `` Well, I will leave you two to get to it '', Dr. Jekyll says as he backs out of the way.

They both stand there for a few arcminute when ally says, `` wellspring I will go first to show you how it is done. ''

mat watches as his baby takes the huge horse tool and sticks it in her mouth and starts to suck on it. matt then watched as she took her paw and started to jack off the buck massive putz. Soon he can see the sawbuck glob tense up and he knew what was going to happen. He could see her struggling to accept the monolithic amount of money of cum from the horses but soon he could see that she couldn't take it any more so she pulled the horses cock out of his oral fissure as it was still cumming and it cummed all over her tiny physical structure. This turned Matt on very a lot and soon he had a big flub watching the buck cum all over his babe.

Soon the Equus caballus was done and Amy turned toward his her chum and said, `` Now it 's your turn '',

matt had not been thinking about what was about to materialise. He walks over to his brown Equus caballus and starts to rub its stopcock. Soon the cock is at full length and Matt just stares at it.

'' I do n't think I can do this '', he says to Ally.

'' Yes, you can, just do what I did '', friend says encouragingly.

Matt then takes the solid cock and puts it into his mouth. He starts to suck on it at the Lapp time jacking off the horse with his hands. Matt loves sucking the horses cock. He can savor the precum oozing from the horse slit and he loves it. Soon the cavalry egg tense up and send ropes of cum down Matt 's pharynx. Before long matt 's tummy is total and he pulls out the turncock from his mouth. The horses dick then starts to shoot cum all over Matt 's body covering him from chief to toe.

Dr. Jekyll then walks into the way and says to the Gemini the Twins, `` Oh, you two are a mess, go back to your stable. '' Matt and Ally comply and follow them back to their stalls. He then puts a pail of cold weewee and a Equus caballus coppice and says to them, `` You two should probably clean up. ''

They then grab the bucket and begin to scratch each former with it focusing on the `` spiritualist '' surface area mostly. This turn goes on everyday for a match of hebdomad. They wake up, have sex, get covered in cum, and then wash each former. Their eubstance go through many more changes as well. Both of their hips get spacious enough to accommodate the horse. There tit swell up in size too. They go all the way to the D-Cup and break off. Their digest keep expanding rapidly in size too. With about a week left hand, it looks like they are both having quadruplets in their stomach. They have to break off having sex because their bellies are so big but they can still find each early up.

Then one day, Dr. Jekyll walks in the elbow room with a box full moon of dildos. He says to the Gemini the Twins, `` Here, these are for flatness. If you want to render this sawhorse without any damage then you will need to act on making your rectum big enough to accommodate this horse."

'' What about me ? ``, says Ally.

'' You should be fine, women are meant to chip in birth and I think that your vagina will do just ticket. ``

The man leaves and matte goes over and looks at the dildos. They are not that long but some of the girths of the dildos were immense.

'' Want to help '', lustrelessness say to Ally.

'' for sure '', friend says, `` Now get into the position. ''

lusterlessness gets on his hands and genu and friend chooses the pocket-sized dildos and penetrates matt 's ass slowly. matte moan because he had been craving having the horses dick in his ass for awhile but he knew that it would spite the foal. She then worked her way up to the self-aggrandising dildo which was as wide as the cavalry gumshoe. She did this every day until one day Matt had some sharp-worded pains in his breadbasket and soon after his sis did too.

They both knew that their foals were coming and started to machinate their selves. Out of instinct, they both lay on their sides because that is how horses normally give nativity. They both yelled as they went through the first compression.

Dr. Jekyll then came running in and says, `` The show has just begun '', and brings a chair over to determine the festivities. They went through compression after contraction together until 12 hr in, Matt felt that he needed to push. He started to push and could feel the horse sliding down his colon. He pushed and pushed until he looked back and could see the headway out. `` Almost there '', Matt thought. The pain was excruciating. He kept pushing and pushing until the front peg popped out, then the back legs popped out after and he was done. His foal crawled over to him and Matt pulled off the membrane from around it. The gymnastic horse then started to absorb on Matt 's tit. The feeling was amazing as he could experience the milk leaving his body and into his horse.

'' Nice job Matt '', Dr. Jekyll says, `` That is a smasher. ``

Matt looks over at Amy and sees that she is struggling to get the foal out of her.

'' You are doing well '', lusterlessness says encouragingly, `` Almost there. ''

matt can see the head startle to come out of his babe pussy. ally keeps pushing and soon the front wooden leg pop out and finally the backrest pegleg. Ally sighs as her foal finally comes out. The two twin then fall asleep with their babies sucking on their tits.

They wake up the next day and they both feel different. Their bodies had gone back to rule. Matt no longer had tits and widened rosehip and friend titmouse and hips had gone done in size as well. They were perplexed. Then they could hear the barn doorway give and in walk Dr. Jekyll into their stall.

'' hi '', Dr. Jekyll says to the Twins, `` You two did a squeamish job yesterday. ''

He looked at their perplexed looks and says, `` There was one Sir Thomas More affair that I did not tell you about when I modified your bodies. After you give nascency, the changes that were made revert back and you look just like you did a month ago. Unless you want to celebrate the changes. ``

'' No, no '', says the similitude in unison.

'' Ok, I bet you have been wondering what your parents are going to suppose when you come back after being gone for a month. Well, when I kidnapped you, your parents were going to send you to camp for a calendar month and I have been sending them letters about all the fun you have been having. Do not state anyone about what happened today unless you want me to release a TV documenting what happened. From you having sex with each early, with a sawhorse, and giving giving birth. Are we clear ? ``

They both nod in agreement. He then tosses in some clothes and tells them to get dressed

Matt had gotten so used to be naked all the time that the clothes feel Weird. They then look at each former and lusterlessness knows that life will never be the Lapplander .
