matt wakes up and looks around groggily at his surround thinking to himself, what just happened. It appears that he was in a horse barn and was naked on his hands in articulatio genus with his dick hanging down from him. He looks to his right and see his counterpart sister ally in the Lapplander position. This was the number 1 meter he had seen her raw in awhile and she was hot with her b cup pap hanging down. The room is black with many empty-bellied stables around. Then the doors to the static give and sunlight outpouring the room making matte have to squint his eyes to see what is happening. The doors closes quickly and he can clearly see a man walking into the elbow room with a big bag. He walks over to his similitude sis and him and puts the bag on the Bench and starts to talk 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 experiment and you were chosen because of some certain qualities… ''

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

The man continues, `` This experimentation will wound, I will assure you that, but when it is over we will sustain created something heaven-sent. ``

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

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

mat can see what he is doing and set out to resist but his voice is cut short when he forcefully sticks two of his finger's breadth into his ass. The feeling is weird. It is terrible and pleasurable at the same time. It is all over quickly though as he retracts his two fingers covered in lube and walks over and takes a 6 inch dildo and pass over and places the tip on Matt 's ass.

'' If you are going to handle what happens side by side, we are going to need 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 palpate the dildo inside of him. He then takes it back a few inches and starts to throw it back and forth creating a rhythm method of birth control. mat grunts from exertion as he is doing this. Then something really weird happens, he starts to get a boner. He had never been gay in his life so he thinks that it is odd that he gets a boner.

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 in dildo and does the same thing. The 8 column inch dildo makes matte feels R. Buckminster Fuller then the 6 inch dildo. As he is ramming the dildo in he can startle to feel his ass getting liberal and looser.

After about five second of the man ramming the dildo in his ass the man says to him, `` You are almost gear up, there is just one more affair I have to do to you to get you ready for the briny issue, I have to pick you from the interior out. ``


He then goes over to his bag and takes out a electron tube attached to a big water bag. He goes over to a hose on the rampart and fills the body of water bag full-of-the-moon of water. The bag must accept been big enough to harbour a gallon. Then he takes the bag and bent it on a hook above him that Matt had not noticed before. lustrelessness think he recognizes the bag from some of the porn he watched. It was an enema, he thought to himself. He then takes the thermionic vacuum tube and takings to stick it right into his already loosened ass.

'' I am going to take you to be really sportsmanlike in there if my experiment is going to work '', the man says.
He then turns a valve and the water starts to course into his ass. mat can feel the cold body of water flow into his ass making it flourish. After a minute he can sense his belly start to exposit and he looks back and his belly looks like he is pregnant. Finally the man closes the valve and slowly starts to take the enema tube out of his ass. As soon as he does this, some chocolate-brown fluid shoots out of his ass and onto the floor. It feels really weird having the liquid state shoot out of lusterlessness 's ass. He then proceeds to put the enema tube back in

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

The man then pulls out walkie-talkie and says into it, `` He is prepare, bring him in. ``

Matt turns around and sees the doors to the barn open and a man walks in directing a entire behind him. `` Oh no '', lustrelessness 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 foot prospicient putz springs out from the horse.

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

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

The man then presses a push on his remote control and the straps holding his custody and pegleg to the primer coat 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 height for the horse to come home his ass. The stallion then rears up and places both its hooves on a bar so that the hooves will not be on lustrelessness. Then the entire starts to throw searching for his hollow. Matt starts to prepare himself for the inevitable. Finally after four or five missed thrusts, the horse finds his gob. At beginning the sawbuck can only fit the orchard apple tree sized tip of his putz into his ass. The knight then begins to lunge his dick further and further into his ass. Finally, after a couple of mo of the horse going abstruse and cryptical into his ass the Equus caballus bottoms out and stands still for a couple of seconds. The nuisance is excruciating. Matt almost blacks out from having the horse dick so far up his ass. Then the knight pulls out six in and drive. He repeats this action and then forms a unremitting beat. The pain in the ass begins to subside and the delight kicks in. Before long he can feel his own prick starting time to shoot off on the level. Then after ten minutes of straight fucking from the buck, he can find the horse 's glob tense up. The horse cavalry then bottoms out and his gumshoe erupts with cum. The hot fluid feels so dependable inside his virgin ass. The rophy of cum cover the inside of his ass and begins to make his ass expand. The horse keeps cumming for about a minute. Finally the Equus caballus stoppage and right as the buck pulls its hawkshaw 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 platform and takes the straps off matte 's legs and hands and he collapses on the ground. He feels so bloated and he looks at his stomach and it looks like he is significant from all the cum inside of him. He can feel it swishing around in his ass and it feels form of good. Then he passes out on the floor….

Matt wakes up on the cold ground naked and looks at himself. His stomach bulged with all the cum inside of him and his ass ached and Matt try to stand up but can not. He looks around and saw that he is in a horses stable. He then turns and looks at his twin sister lying next to him bare. She too had a stomach that bulged like she was fraught too but she still looked sexy. Matt could see her B-cup tits because she was lying on her back and her beautiful pussy with just a niggling tuft of hairsbreadth at the top of her slit. His shaft starts to grow but at that same import she woke up.

'' What happened '', proclaims Ally.

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

Matt looks over at Ally and says, `` Did the horse… ''

'' Fuck my pussy, says friend, `` Yeah ''

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

'' Rise and shine boy 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 separate you yesterday to spoil the surprise but here we go. Those 2 horses yesterday that you had a little fun with, were normal. I genetically modified you and you sister to get impregnated by any creature. I also modified the prison term the gestation will take to form it go from 9 months to 1 month so you will feel changes pretty soon. Another thing is that the reason I plugged up your pickle from letting the cum seep out was because the wight cum takes about 4 minute to impregnate you. The understanding I wanted to do this was because I wanted to create the expectant horse ever. I could not do this with mating 2 gymnastic horse together but I had to couple a horse cavalry with a man because with a human, the horse can be very intelligent. The reason I picked you 2 was because you both have high IQ 's, are acrobatic and it looked like you could handle this. And I thought it would be fun to have a brother and sis. Oh, and by the way, my name is Dr. Jekyll Any questions ? ``

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

'' Oh, I am quite grave '', Dr. Jekyll says, `` I have given you, ah I don't want to get into specifics. Any Sir Thomas More questions ? ``

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

'' Well your trunk will be changing to lodge the foals but it will still smart very much '', Dr. Jekyll
says, '' It will probably hurt more than a normal pregnancy so be prepared. You will stay here in this stable for the remainder of this pregnancy. Oh, and one more thing. ``

Dr. Jekyll then walks over to Matt and pulls out the but plug holding all the Equus caballus cum inside of him. The cum shoots out of his ass and all over the concrete floor of the stalls. He then pulls the sparking plug out of
Ally and says, `` wellspring I hope that this semen did its affair. ''

He then walks out of the stable leaving Matt and ally laying in piles of cum. They both sighed out of
relievo when the cum was finally out of their cunt and stern.

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

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

Matt then lays on the ground in his syndicate 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 elbow room. flatness front crawl over and gets the 2 pail and brings them over to ally.
friend gives Matt a nonplussed facial expression and he just shrugs it off. He then takes a fistful of the food grain and puts chow it. `` It 's not that bad '', says Matt.

'' Yeah right '', says ally

She then tries the grain and agrees with Matt. They could accept probably eaten anything at the moment.
They had not eaten anything in awhile and they were both very hungry. They then took turns sipping water from the bucket until the bucketful was drained. They then fall asleep on the cold concrete.

Matt wakes up first the adjacent morning and flavour different. He feels a weight on his chest and looks down and sees that he has some A-Cup tits. His rose hip had widened too and his belly was a little bloated. His ass also did not sense sore anymore. He looks over and sees his sister awake as well. He could see that she also had modification. Her hips had widened and her knocker went from an A to a B-cup. He then hears a titter cum from his baby.

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

'' zero '', Ally says, `` That was quite the experience we had yesterday. ``

'' Yeah '', Matt says, `` It hurt at for the first time but after awhile it felt really near. ``

'' Yeah '', ally says, `` The sawbuck big dick felt so good in my kitty-cat. The sound part was when he cummed, it
was so bully that it gave me the best orgasm I had ever had. ''

'' Are those literal ? '' Ally says pointing to her brothers tits.

'' Yeah, unfortunately they are. I think that this is one of the side core. '' lustrelessness says, `` sense them if you do not consider me. ''

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

lustrelessness then places his workforce on his sisters B-Cup tits. Ally too lets out a modest moan as he does this. Ally 's tits felt so good in his hands. He had always admired them and now he was doing the matter he had only dreamt of doing. Her tits were the consummate size and they were still truehearted. Matt then wanted to ingest it a little further. He takes one hand off her tit and started to go it down her physical structure. He reaches her button and starts to rub it.

Her organic structure shook violently as the orgasm went through her whole physical structure. After the orgasm was over, she said to her comrade, `` Now your crook. ``

She then grabbed his already hard cock and put it into her rima oris. She started to suck his cock and massaging his balls at the Lapplander time. Matt could experience his sister sucking on his cock, licking the tip every once in awhile. Then he could feel his testicle tense up and he said to ally, I am going to cum. '' Matt could then feel Ally start to deep pharynx his pecker. Matt then erupted with cum and then photograph it all down his Sister throat.

matt then took his prick out of his Sister throat and picked her up and laid her in a corner on the hay. He then took his 8 inch hammer and directed it into her awaiting pussy. He pushed in slowly not wanting to spite his sis. Finally after a petty of pushing, he could feel his chunk rub up against her ass.

'' Are you ready '', asks Matt.

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

Matt then pulls out and slams into his sis. He then started a rhythm and he could feel the precum dripping out. His stopcock feels so good with his Sister pussy enveloping it. After what seems like an eternity, mat can experience his balls tense up and he goes hilt cryptic and cums into his sister as hard as he can.

They both lay there for a few moments with matt 's dick still in his sisters 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 pass off. 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. mat then pulled his semitrailer difficult dick out of his sisters pussy and a little current of cum followed after that.

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

He then leads the two of them out of a kiosk and into another sales booth where both their horses were kept.
The black one was Ally 's and the brown one was Matt 's. `` Well, I will will you two to get to it '', Dr. Jekyll says as he backs out of the room.

They both stand there for a few minutes when friend says, `` Well I will go first to establish you how it is done. ''

Matt watches as his babe takes the immense horse cock and joystick it in her back talk and starts to suck on it. Matt then watched as she took her hands and started to jacklight off the Equus caballus massive putz. Soon he can see the knight egg tense up and he knew what was going to happen. He could see her struggling to accept the monolithic amounts of cum from the horses but soon he could see that she couldn't take it any more so she pulled the Equus caballus cock out of his mouth as it was still cumming and it cummed all over her petite trunk. This turned Matt on very much and soon he had a big boner watching the horse cum all over his Sister.

Soon the horse was done and Amy turned toward his her brother and said, `` Now it 's your turn '',

Matt had not been thinking about what was about to happen. He walks over to his brown horse and starts to rub its cock. 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 '', Ally says encouragingly.

Matt then takes the unanimous cock and puts it into his rima oris. He starts to blow on it at the Lapplander fourth dimension jacking off the horse with his hands. Matt loves sucking the sawbuck cock. He can taste the precum oozing from the horses slit and he loves it. Soon the knight ball tense up and send ropes of cum down Matt 's throat. Before retentive Matt 's stomach is full and he pulls out the hammer from his sass. The cavalry dick then starts to tear cum all over matt 's body covering him from head to toe.

Dr. Jekyll then walks into the way and says to the twins, `` Oh, you two are a passel, go back to your stable. '' Matt and ally comply and follow them back to their stable. He then puts a pail of low temperature water and a buck thicket and says to them, `` You two should probably clean up. ''

They then grab the bucketful and lead off to scour each former with it focusing on the `` sensitive '' areas mostly. This everyday goes on everyday for a couple of weeks. They wake up, have sex, get covered in cum, and then wash each other. Their bodies go through many more changes as well. Both of their rose hip get wide enough to accommodate the horse cavalry. There tits swell up in size too. They go all the way to the D-Cup and block. Their stomachs hold back expanding rapidly in size too. With about a calendar week left, it looks like they are both having quadruplets in their stomachs. They have to block off having sex because their belly are so big but they can still finger each other up.

Then one day, Dr. Jekyll walk of life in the room with a box wide-cut of dildos. He says to the twins, `` Here, these are for lustrelessness. If you want to extradite this Equus caballus without any equipment casualty then you will want to exercise on making your rectum big enough to hold this horse."

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

'' You should be very well, charwoman are meant to give birth and I think that your vagina will do just ticket. ``

The man leaves and Matt goes over and looks at the dildos. They are not that long but some of the cinch of the dildos were huge.

'' Want to facilitate '', Matt say to Ally.

'' Sure '', friend says, `` Now get into the position. ''

matt gets on his hands and knees and ally chooses the smallest dildos and penetrates mat 's ass slowly. flatness moan because he had been craving having the horses dick in his ass for awhile but he knew that it would injure the foal. She then worked her way up to the biggest dildo which was as wide-eyed as the horses tool. She did this every day until one day flatness had some sharp pain in his stomach and soon after his sister did too.

They both knew that their foals were coming and started to prepare their ego. 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 foremost contraction.

Dr. Jekyll then came running in and says, `` The show has just begun '', and brings a electric chair over to watch the festivities. They went through muscle contraction after contraction together until 12 hr in, Matt felt that he needed to push. He started to labour and could feel the horse sliding down his Aspinwall. He pushed and pushed until he looked back and could see the head out. `` Almost there '', Matt thought. The pain was excruciating. He kept pushing and pushing until the nominal head legs popped out, then the back legs popped out after and he was done. His foal crawled over to him and matte pulled off the tissue layer from around it. The horse then started to fellate 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 beauty. ``

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

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

matt can see the head start to come out of his sister pussy. Ally keeps pushing and soon the movement legs pop out and finally the spinal column legs. ally sighs as her foal finally comes out. The two twins 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 normal. matte no longer had tits and widened rose hip and Ally boob and hip had gone done in sizing as well. They were perplexed. Then they could hear the b doors open and in walk Dr. Jekyll into their stall.

'' Hello '', Dr. Jekyll says to the twins, `` You two did a nice job yesterday. ''

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

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

'' Ok, I bet you have been wondering what your parents are going to think when you come back after being gone for a month. Well, when I kidnapped you, your parents were going to place you to camp for a month and I have been sending them letter about all the fun you have been having. Do not tell anyone about what happened today unless you want me to put out a video documenting what happened. From you having sex with each other, with a sawhorse, and giving birth. Are we clear ? ``

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

matte had gotten so victimized to be naked all the time that the clothes feel Wyrd. They then look at each former and flatness knows that life will never be the same .
