Matt wakes up and looks around groggily at his surroundings thinking to himself, what just happened. It appears that he was in a stable and was naked on his hands in knees with his dick hanging down from him. He looks to his right and see his Twin babe friend in the same position. This was the first clip he had seen her bare in awhile and she was hot with her b cup mammilla hanging down. The room is dismal with many empty-bellied horse barn around. Then the threshold to the horse barn open and sun floods the elbow room making Matt have to squinch his centre to see what is happening. The doors closes quickly and he can clearly see a man walking into the way with a big bag. He walks over to his twin sister 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 '', Matt pleads.

The man continues, `` This experiment will hurt, I will recite you that, but when it is over we will accept created something miraculous. ``

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

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

Matt can see what he is doing and begin to dissent but his voice is cut short when he forcefully sticks two of his finger into his ass. The feeling is weird. It is irritating and pleasurable at the same metre. It is all over quickly though as he retracts his two fingers covered in lube and walkway over and takes a 6 inch dildo and walkway over and places the tip on Matt 's ass.

'' If you are going to handle what happens next, 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 Lapp feeling comes over him as Matt can finger the dildo inside of him. He then takes it back a few inches and starts to push up it back and forth creating a musical rhythm. mat grunts from elbow grease as he is doing this. Then something really weird happens, he starts to get a pratfall. 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 in dildo makes Matt tone Buckminster Fuller then the 6 in dildo. As he is ramming the dildo in he can start to palpate his ass getting idle and looser.

After about five instant of the man ramming the dildo in his ass the man says to him, `` You are almost ready, there is just one more matter I have to do to you to get you prepare for the main case, I have to clean you from the interior out. ``


He then goes over to his bag and takes out a underground attached to a big H2O bag. He goes over to a hose on the bulwark and fills the weewee bag full of water. The bag must have been big enough to support a gallon. Then he takes the bag and hangs it on a hook above him that Matt had not noticed before. lusterlessness think he recognizes the bag from some of the smut he watched. It was an enema, he thought to himself. He then takes the subway system and take to amaze it right into his already loosened ass.

'' I am going to need you to be really clean in there if my experimentation is going to work '', the man says.
He then turns a valve and the water system starts to flow into his ass. Matt can feel the cold water flow into his ass making it flesh out. After a minute he can feel his belly start to exposit and he looks back and his belly looks like he is meaning. 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 brown fluid shoots out of his ass and onto the story. It feels really weird having the liquid state shoot out of Matt 's ass. He then proceeds to put the clyster subway system back in

mat 's ass and does 3 times 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. ``

mat turns around and sees the doorway to the barn open 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 foot long cock outpouring out from the horse.

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

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

The man then presses a button on his remote and the strap holding his work force and peg to the soil tighten and he is lifted up into the air on a political program that he was on that he had not noticed before. The platform stops at the perfect tense summit for the horse to dawn his ass. The stallion then rears up and places both its hooves on a bar so that the hooves will not be on Matt. Then the stallion starts to thrust searching for his hole. lusterlessness starts to prepare himself for the inevitable. Finally after four or five missed thrusts, the horse finds his cakehole. At first the horse can only fit the orchard apple tree sized tip of his gumshoe into his ass. The horse then begins to pierce his prick further and further into his ass. Finally, after a couple of moment of the knight going deeper and deeper into his ass the horse bottoms out and stands still for a duad of instant. The pain is excruciating. lusterlessness almost blacks out from having the sawhorse dick so far up his ass. Then the sawbuck pulls out six inches and thrusts. He repeats this activeness and then forms a invariable rhythm. The botheration begins to subside 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 sawbuck, he can feel the horse 's balls tense up. The buck then bottoms out and his cock erupts with cum. The hot fluid feels so good inside his Virgin ass. The ropes 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 horse occlusion and rightfield as the knight pulls its dick out of him the man puts a but stopple in.

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



He then lowers the platform and takes the strap off mat 's pegleg and hands and he collapses on the solid ground. He feels so bloated and he looks at his stomach and it looks like he is fraught from all the cum inside of him. He can finger it swishing around in his ass and it feels sort of good. Then he passes out on the floor….

lustrelessness wakes up on the cold reason naked and looks at himself. His abdomen bulged with all the cum inside of him and his ass ached and mat tries to digest up but can not. He looks around and saw that he is in a horses horse barn. He then turns and looks at his similitude baby lying next to him nude. She too had a abdomen that bulged like she was pregnant too but she still looked aphrodisiac. Matt could see her B-cup mammilla because she was lying on her back and her beautiful pussy with just a little tuft of hair at the top of her scratch. His cock starts to grow but at that same mo she woke up.

'' What happened '', proclaims Ally.

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

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

'' nookie my kitty-cat, says Ally, `` Yeah ''

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

'' Rise and radiance boys and girls '', the man says, `` I bet you have been wondering what the experiment I
preformed on you was for. I didn't want to secern you yesterday to spoil the surprisal but here we go. Those 2 horse yesterday that you had a little fun with, were convention. I genetically modified you and you sister to get impregnated by any creature. I also modified the time the pregnancy will take to lay down it go from 9 month to 1 month so you will experience changes pretty soon. Another thing is that the grounds I plugged up your muddle from letting the cum seep out was because the wight cum takes about 4 hours to impregnate you. The reason 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 sawhorse with a human because with a human, the horse can be very reasoning. The reason I picked you 2 was because you both have eminent IQ 's, are athletic and it looked like you could handle this. And I thought it would be fun to have a crony and sister. Oh, and by the way, my name is Dr. Jekyll Any questions ? ``

matt speaks up, `` You can not be serious, there is no way that I can be… meaning. ``

'' Oh, I am quite sober '', Dr. Jekyll says, `` I have given you, ah I don't want to get into particular. Any more inquiry ? ``

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

'' Well your body will be changing to suit the foals but it will still hurt very a great deal '', Dr. Jekyll
says, '' It will probably hurt more than a pattern maternity so be prepared. You will stay here in this stable for the remainder of this pregnancy. Oh, and one more than thing. ``

Dr. Jekyll then walks over to Matt 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 level of the stable. He then pulls the plug out of
Ally and says, `` Well I hope that this ejaculate did its matter. ''

He then walks out of the stable leaving matt and friend laying in piles of cum. They both sighed out of
substitute when the cum was finally out of their kitty and asses.

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

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

Matt then lays on the ground in his pool of cum, thinking about the consequence that happened yesterday. Then the man walks into the stable and says, `` Here 's dinner party. ``

Then he walks out of the room. matte crawls over and gets the 2 bucket and brings them over to ally.
friend gives Matt a puzzled look and he just shrugs it off. He then takes a handful of the texture and puts grub it. `` It 's not that bad '', says Matt.

'' Yeah the right way '', says ally

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

matte wakes up first the next daybreak and tone different. He feels a weighting on his dresser and looks down and sees that he has some A-Cup tits. His hips had widened too and his stomach was a small bloated. His ass also did not feel sore anymore. He looks over and sees his sister awake as well. He could see that she also had modification. Her pelvic arch had widened and her knocker went from an A to a B-cup. He then hears a giggle come from his sister.

'' What 's so good story '', matt says to Ally.

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

'' Yeah '', matt says, `` It hurt at first of all but after awhile it felt really effective. ``

'' Yeah '', ally says, `` The horses big dick felt so proficient in my pussy. The respectable part was when he cummed, it
was so great that it gave me the upright coming I had ever had. ''

'' Are those real ? '' friend says pointing to her crony tits.

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

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

matte then places his hands on his babe B-Cup tit. Ally too lets out a low moan as he does this. Ally 's teat felt so soundly in his hands. He had always admired them and now he was doing the thing he had only dreamt of doing. Her tits were the perfect size and they were still firm. lustrelessness then wanted to take it a petty further. He takes one hand off her tit and started to move it down her trunk. He reaches her clit and starts to rub it.

Her consistency shook violently as the orgasm went through her hale dead body. After the orgasm was over, she said to her brother, `` Now your spell. ``

She then grabbed his already toilsome pecker and put it into her oral fissure. She started to suck in his hammer and massaging his balls at the same time. Matt could feel his sis sucking on his turncock, licking the tip every once in awhile. Then he could sense his nut tense up and he said to ally, I am going to cum. '' Matt could then feel Ally start to deep pharynx his rooster. mat then erupted with cum and then bourgeon it all down his babe throat.

Matt then took his prick out of his sisters throat 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 experience his balls rub up against her ass.

'' Are you ready '', asks Matt.

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

Matt then pulls out and slam into his Sister. He then started a rhythm and he could feel the precum dripping out. His cock feels so good with his sister pussy enveloping it. After what seems like an eternity, Matt can feel his clump tense up and he goes hilt deep and cum into his sister as hard as he can.

They both lay there for a few import with matt 's peter still in his sister pussy and that 's when they heard mortal clapping.

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

matte and Ally both blushed as they both thought about what just happened. What made it even worse was that individual had seen them do it. Matt then pulled his semi intemperately pecker out of his sisters pussy and a short flow of cum followed after that.

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

He then leads the two of them out of a stall and into another stand where both their horse cavalry were kept.
The black one was ally 's and the brown one was Matt 's. `` Well, I will leave 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 show you how it is done. ''

mat picket as his sister takes the immense horse prick and sticks it in her mouth and starts to suck on it. flatness then watched as she took her hands and started to jack off the horses massive prick. Soon he can see the buck balls tense up and he knew what was going to happen. He could see her struggling to take back the massive sum of money of cum from the cavalry but soon he could see that she couldn't take it any more so she pulled the cavalry cock out of his rima oris as it was still cumming and it cummed all over her petite consistency. This turned matte on very much and soon he had a big blunder watching the gymnastic horse cum all over his sister.

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

flatness had not been thinking about what was about to happen. He walks over to his chocolate-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 '', friend says encouragingly.

mat then takes the altogether cock and puts it into his mouth. He starts to breastfeed on it at the Saame meter jacking off the horse with his paw. Matt loves sucking the Equus caballus rooster. He can savour the precum oozing from the horses incision and he loves it. Soon the buck glob tense up and post ropes of cum down flatness 's throat. Before long Matt 's abdomen is replete and he pulls out the cock from his backtalk. The horses dick then starts to burgeon forth cum all over Matt 's trunk covering him from head to toe.

Dr. Jekyll then walks into the room and says to the twin, `` Oh, you two are a mess, go back to your stalls. '' Matt and friend comply and follow them back to their static. He then puts a bucket of cold water and a buck light touch and says to them, `` You two should probably scavenge up. ''

They then grab the bucket and begin to scrub each early with it focusing on the `` medium '' region mostly. This workaday goes on everyday for a match of workweek. They wake up, have sex, get covered in cum, and then wash each other. Their bodies go through many more change as well. Both of their hips get spacious enough to accommodate the horse. There tits swell up in size of it too. They go all the way to the D-Cup and finish. Their abide keep expanding rapidly in size of it too. With about a week left hand, it looks like they are both having quadruplets in their venter. They have to bar having sex because their belly are so big but they can still finger each early up.

Then one day, Dr. Jekyll walkway in the way with a box full of dildos. He says to the twin, `` Here, these are for matte. If you want to surrender this buck without any damage then you will demand to work on making your rectum big enough to accommodate this horse."

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

'' You should be amercement, charwoman are meant to open birth and I think that your vagina will do just fine. ``

The man leaves and lusterlessness goes over and looks at the dildos. They are not that long but some of the girth of the dildos were Brobdingnagian.

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

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

Matt gets on his hands and human knee and ally chooses the pocket-sized dildos and penetrates lusterlessness 's ass slowly. mat moans because he had been craving having the horses dick in his ass for awhile but he knew that it would smart the foal. She then worked her way up to the prominent dildo which was as wide as the horse peter. She did this every day until one day Matt had some precipitous pain sensation in his stomach and soon after his sister did too.

They both knew that their foals were coming and started to set 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 muscular contraction.

Dr. Jekyll then came running in and says, `` The show has just begun '', and brings a chair over to watch the celebration. They went through contraction after contraction together until 12 minute in, flatness felt that he needed to push. He started to labor and could feel the gymnastic horse sliding down his colon. He pushed and pushed until he looked back and could see the head word out. `` Almost there '', matte thought. The pain was excruciating. He kept pushing and pushing until the front legs popped out, then the back legs popped out after and he was done. His foal crawled over to him and mat pulled off the membrane from around it. The horse then started to give suck on flatness 's tit. The feeling was amazing as he could feel the Milk River leaving his body and into his horse.

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

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

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

Matt can see the head start to come out of his baby pussy. Ally keeps pushing and soon the front legs pop out and finally the backrest ramification. 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 future day and they both feel different. Their consistency had gone back to pattern. Matt no longer had tits and widened hips and ally pap and hips had gone done in size as well. They were perplexed. Then they could get wind the barn doors unresolved and in walked Dr. Jekyll into their stall.

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

He looked at their gravel looks and says, `` There was one to a greater extent thing that I did not enjoin you about when I modified your eubstance. After you give parturition, the modification that were made revert back and you look just like you did a month ago. Unless you want to prevent the variety. ``

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

'' Ok, I bet you have been wondering what your parents are going to guess when you come back after being gone for a month. Well, when I kidnapped you, your parents were going to broadcast you to tent for a month and I have been sending them letters about all the fun you have been having. Do not assure anyone about what happened today unless you want me to release a video documenting what happened. From you having sex with each other, with a horse, and giving birth. Are we sack up ? ``

They both nod in understanding. He then tosses in some clothes and tells them to get garb

matte had gotten so used to be naked all the time that the apparel feel weird. They then look at each early and Matt knows that life will never be the same .
