mat 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 pecker hanging down from him. He looks to his right and see his twin sister ally in the Saame position. This was the showtime time he had seen her naked in awhile and she was hot with her b cup mammilla hanging down. The room is moody with many empty stables around. Then the doors to the stable spread and sun floods the room making Matt have to squint his eyes to see what is happening. The doorway closes quickly and he can clearly see a man walking into the elbow room with a big bag. He walks over to his twin Sister and him and puts the bag on the terrace 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 experimentation will ache, I will tell you that, but when it is over we will own created something providential. ``

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 mitt and vex his fingers into the lube.

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

'' If you are going to palm what happens adjacent, we are going to demand to loosen you up first '', the man says.

He pushes the dildo slowly into his ass before finally bottoming out. The Saami look comes over him as Matt can feel the dildo inside of him. He then takes it back a few column inch and starts to force it back and forth creating a rhythm. Matt grunts from exertion as he is doing this. Then something really weird happens, he starts to get a bloomer. He had never been gay in his liveliness so he thinks that it is odd that he gets a bungle.

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 like thing. The 8 in dildo makes Matt feels Buckminster Fuller then the 6 column inch dildo. As he is ramming the dildo in he can start to experience his ass getting liberal and looser.

After about five transactions 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 ready for the main event, I have to clean you from the inside out. ``


He then goes over to his bag and takes out a tube attached to a big piddle bag. He goes over to a hosepipe on the paries and fills the water bag broad of body of water. The bag must own been big enough to prevail a gallon. Then he takes the bag and bent it on a bait above him that lustrelessness had not noticed before. lusterlessness think he recognizes the bag from some of the porn he watched. It was an clyster, he thought to himself. He then takes the subway and proceeds to hold fast it right into his already loosened ass.

'' I am going to need you to be really neat in there if my experiment is going to form '', the man says.
He then turns a valve and the water supply starts to course into his ass. matt can feel the inhuman H2O flow into his ass making it inflate. After a moment he can feel his belly start to lucubrate and he looks back and his belly looks like he is pregnant. Finally the man closes the valve and slowly starts to subscribe the clyster tube out of his ass. As soon as he does this, some brown smooth shoots out of his ass and onto the storey. It feels really weird having the liquidity shoot out of Matt 's ass. He then proceeds to put the enema tubing 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, bring him in. ``

mat turns around and sees the doors 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 prospicient cock saltation out from the horse.

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

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

The man then presses a button on his remote and the shoulder strap holding his hands and ramification to the ground tighten and he is lifted up into the air on a political platform that he was on that he had not noticed before. The weapons platform stops at the perfect height for the horse to diffuse his ass. The entire then rears up and place both its hooves on a bar so that the hooves will not be on Matt. Then the stallion starts to throw searching for his golf hole. Matt starts to prepare himself for the inevitable. Finally after four or five miss thrusts, the cavalry finds his gob. At first the buck can only fit the orchard apple tree sized tip of his hawkshaw into his ass. The horse then begins to thrust his pecker further and further into his ass. Finally, after a mates of minutes of the horse going bass and deep into his ass the sawhorse bottoms out and stands still for a couple of minute. The painfulness is excruciating. Matt almost blacks out from having the horse cavalry dick so far up his ass. Then the horse pulls out six in and thrusts. He repeats this action and then forms a constant rhythm. The pain begins to sink and the pleasure kicks in. Before long he can finger his own putz jump to dash off on the floor. Then after ten minutes of direct fucking from the horse, he can feel the horse 's balls tense up. The horse then bottoms out and his gumshoe erupts with cum. The hot fluid look so serious inside his Virgo the Virgin ass. The Mexican valium of cum cover the inside of his ass and begins to make his ass expand. The gymnastic horse keeps cumming for about a minute. Finally the horse stops and right 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 program and takes the straps off lustrelessness 's branch and paw and he collapses on the basis. 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 palpate it swishing around in his ass and it feels kind 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 mat tries to stand up but can not. He looks around and saw that he is in a knight stalls. He then turns and looks at his twin sister lying future to him raw. She too had a stomach that bulged like she was pregnant too but she still looked sexy. Matt could see her B-cup tits because she was lying on her rear and her beautiful pussy with just a little tuft of fuzz at the top of her slit. His turncock starts to grow but at that same moment she woke up.

'' What happened '', proclaims Ally.

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

matt looks over at friend and says, `` Did the horse… ''

'' shtup my cunt, says Ally, `` Yeah ''

Matt then hears the threshold to the barn undetermined and eyes the man as he walks into their stable.

'' Rise and shine boy 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 tell apart you yesterday to spoil the surprise but here we go. Those 2 horse yesterday that you had a trivial fun with, were normal. I genetically modified you and you sister to get impregnated by any creature. I also modified the meter the pregnancy will take to prepare it go from 9 months to 1 month so you will finger changes pretty soon. Another matter is that the reason I plugged up your holes from letting the cum seep out was because the animate being 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 match a knight with a human because with a human being, the horse can be very intelligent. The reason I picked you 2 was because you both have high IQ 's, are athletic and it looked like you could manage this. And I thought it would be fun to get a brother and sister. Oh, and by the way, my name is Dr. Jekyll Any inquiry ? ``

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

'' Oh, I am quite dangerous '', Dr. Jekyll says, `` I have given you, ah I don't want to get into specifics. Any more than questions ? ``

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

'' Well your bodies will be changing to accommodate the foals but it will still injure very much '', Dr. Jekyll
says, '' It will probably injure more than a normal pregnancy so be prepared. You will stay here in this horse barn for the difference of this pregnancy. Oh, and one Thomas More 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 floor of the stable. He then pulls the stopper out of
Ally and says, `` Well I hope that this cum did its affair. ''

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

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

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

lusterlessness then lays on the ground 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 way. mat crawls over and gets the 2 buckets and brings them over to ally.
Ally gives flatness a puzzled aspect and he just shrugs it off. He then takes a smattering of the grain and puts eats it. `` It 's not that bad '', says Matt.

'' Yeah correctly '', says Ally

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

Matt wakes up first the next break of day and feels dissimilar. He feels a weight on his chest and looks down and sees that he has some A-Cup tits. His hips had widened too and his tum was a minuscule 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 change. Her hips had widened and her pap went from an A to a B-cup. He then hears a giggle come from his babe.

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

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

'' Yeah '', Matt says, `` It hurt at commencement but after awhile it felt really good. ``

'' Yeah '', Ally says, `` The horses big dick felt so undecomposed in my twat. The advantageously role was when he cummed, it
was so great that it gave me the better orgasm I had ever had. ''

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

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

She then walks over to Matt and places her handwriting on his teat. matt was shaking in expectation for this and lets out a small-scale moan as she places her bridge player on his nipple and starts to feel around. ally then said to him, `` You can feel my breast if you want. ``

flatness then places his helping hand on his sisters B-Cup boob. ally too lets out a small 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 thing he had only dreamt of doing. Her tits were the consummate sizing and they were still firm. Matt then wanted to take it a little further. He takes one deal off her tit and started to locomote it down her trunk. He reaches her clitoris and starts to rub it.

Her body shook violently as the orgasm went through her whole body. After the sexual climax was over, she said to her brother, `` Now your twist. ``

She then grabbed his already laborious turncock and put it into her mouth. She started to suck his cock and massaging his testicle at the same time. lusterlessness could feel his sister sucking on his cock, licking the tip every once in awhile. Then he could finger his balls tense up and he said to ally, I am going to cum. '' Matt could then palpate Ally start to deep throat his cock. matte then erupted with cum and then scoot it all down his baby throat.

matt then took his cock out of his sisters pharynx and picked her up and laid her in a recess on the hay. He then took his 8 inch putz and directed it into her awaiting pussy. He pushed in slowly not wanting to smart his sister. Finally after a little of pushing, he could sense his balls rub up against her ass.

'' Are you ready '', asks Matt.

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

flatness then pulls out and bang into his sister. He then started a rhythm and he could sense the precum dripping out. His dick feels so honorable with his sis pussy enveloping it. After what seems like an eternity, mat can palpate his balls tense up and he goes hilt inscrutable and ejaculate into his baby as hard as he can.

They both lay there for a few moments with Matt 's pecker 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 happen. He then said, `` Bravo you two. That was quite the appearance. ''

Matt and friend both blushed as they both thought about what just happened. What made it even worse was that mortal had seen them do it. matt then pulled his semi concentrated putz out of his sisters pussy and a petty watercourse of cum followed after that.

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

He then leads the two of them out of a stall and into another stall where both their horses were kept.
The Negro one was friend 's and the brown one was Matt 's. `` wellspring, I will exit you two to get to it '', Dr. Jekyll says as he backs out of the room.

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

matt watches as his sister takes the huge horse cock and joint it in her mouth and starts to suck on it. Matt then watched as she took her hired hand and started to jack up off the horses massive dick. Soon he can see the horses balls tense up and he knew what was going to happen. He could see her struggling to swallow the monumental total of cum from the horse cavalry but soon he could see that she couldn't take it any more so she pulled the horse cock out of his mouth as it was still cumming and it cummed all over her tiny torso. This turned Matt on very much and soon he had a big boner watching the horse cum all over his sis.

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 Robert Brown horse and starts to rub its shaft. Soon the putz is at full length and mat 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.

matte then takes the whole tool and puts it into his mouth. He starts to suck on it at the Sami time jacking off the horse with his hands. lusterlessness loves sucking the sawhorse stopcock. He can savour the precum oozing from the horse pussy and he loves it. Soon the horse cavalry balls tense up and mail forget me drug of cum down lustrelessness 's pharynx. Before longsighted Matt 's abdomen is replete and he pulls out the cock from his rima oris. The horses dick then starts to photograph cum all over Matt 's body covering him from drumhead to toe.

Dr. Jekyll then walks into the elbow room and says to the Twin Falls, `` Oh, you two are a sight, go back to your stable. '' Matt and friend comply and follow them back to their stable. He then puts a bucket of insensate water and a knight brush and says to them, `` You two should probably clean house up. ''

They then grab the bucket and begin to scratch each early with it focusing on the `` sensitive '' country mostly. This routine goes on everyday for a couple of calendar week. They wake up, have sex, get covered in cum, and then wash each other. Their dead body go through many more than changes as well. Both of their articulatio coxae get wide enough to conciliate the horse. There titty swell up in size too. They go all the way to the D-Cup and stop. Their stomachs hold on expanding rapidly in size of it too. With about a calendar week left hand, it looks like they are both having foursome in their stomachs. They have to hold back having sex because their abdomen are so big but they can still sense each former up.

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

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

'' You should be exquisitely, women 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 girths of the dildos were huge.

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

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

Matt gets on his hands and knees and Ally chooses the pocket-size dildos and penetrates Matt 's ass slowly. Matt groan because he had been craving having the buck dick in his ass for awhile but he knew that it would hurt the foal. She then worked her way up to the biggest dildo which was as panoptic as the horses dick. She did this every day until one day lustrelessness had some sharp pains in his stomach and soon after his sister did too.

They both knew that their foals were coming and started to gear up their selves. Out of instinct, they both lay on their slope because that is how Equus caballus normally give birthing. They both yelled as they went through the kickoff muscular contraction.

Dr. Jekyll then came running in and says, `` The show has just begun '', and brings a chairperson over to follow the festivities. They went through contraction after contraction together until 12 hours in, Matt felt that he needed to push. He started to promote and could sense the horse sliding down his colon. 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 front legs popped out, then the back stage popped out after and he was done. His foal crawled over to him and Matt pulled off the membrane from around it. The horse cavalry then started to suck on flatness 's tit. The intuitive feeling was amazing as he could feel 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 '', lustrelessness says encouragingly, `` most there. ''

Matt can see the guide starting time to come up out of his Sister pussy. Ally keeps pushing and soon the front legs pop out and finally the back ramification. Ally sighs as her foal finally comes out. The two twins then fall asleep with their sister sucking on their tits.

They wake up the next day and they both feel different. Their bodies had gone back to normal. Matt no longer had tits and widened hips and Ally bosom and pelvic girdle had gone done in size as well. They were perplexed. Then they could see the b doors undefendable and in walked Dr. Jekyll into their stall.

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

He looked at their perplexed looks and says, `` There was one More affair that I did not secernate you about when I modified your physical structure. After you give parentage, the changes that were made revert back and you look just like you did a month ago. Unless you want to sustain the changes. ``

'' No, no '', says the twins 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. wellspring, when I kidnapped you, your parents were going to beam you to camp down for a calendar month and I have been sending them letters about all the fun you have been having. Do not tell anyone about what happened today unless you want me to loose a video documenting what happened. From you having sex with each early, with a horse, and giving birth. Are we clean ? ``

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

lusterlessness had gotten so ill-used to be naked all the time that the apparel feel Weird. They then look at each early and lustrelessness knows that life will never be the like .
