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 hawkshaw hanging down from him. He looks to his right and see his twin sister Ally in the Lapp location. This was the first time he had seen her au naturel in awhile and she was hot with her b cup pap hanging down. The room is dark with many void stalls around. Then the threshold to the stable spread and sunlight inundation the room making Matt have to squint his eyes to see what is happening. The threshold closes quickly and he can clearly see a man walking into the elbow room with a big bag. He walks over to his twin baby and him and puts the bag on the bench and starts to tattle to them.

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

His baby 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 '', lustrelessness pleads.

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

He then walks over to Matt and says, `` We will originate 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 digit into the lube.

Matt can see what he is doing and begin to protest but his voice is cut unforesightful when he forcefully sticks two of his finger into his ass. The tone is eldritch. It is terrible and pleasurable at the Saame sentence. 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 walks over and places the tip on Matt 's ass.

'' If you are going to cover what happens succeeding, we are going to need to relax you up first '', the man says.

He pushes the dildo slowly into his ass before finally bottoming out. The same feel comes over him as Matt can feel the dildo inside of him. He then takes it back a few inches and starts to hurtle it back and Forth creating a rhythm. lustrelessness oink from effort as he is doing this. Then something really unearthly happens, he starts to get a bungle. He had never been gay in his life so he thinks that it is odd that he gets a botch.

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 Lapp thing. The 8 inch dildo makes lusterlessness tone Buckminster Fuller then the 6 inch dildo. As he is ramming the dildo in he can begin to find his ass getting looser and looser.

After about five bit of the man ramming the dildo in his ass the man says to him, `` You are almost ready, there is just one more thing I have to do to you to get you ready for the main event, I have to houseclean you from the inside out. ``


He then goes over to his bag and takes out a pipe attached to a big water bag. He goes over to a hosepipe on the bulwark and fills the water system bag full of water. The bag must induce 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. lusterlessness think he recognizes the bag from some of the erotica he watched. It was an enema, he thought to himself. He then takes the tube and return to stick to it right into his already loosened ass.

'' I am going to need you to be really white in there if my experiment is going to mould '', the man says.
He then turns a valve and the water starts to flow into his ass. Matt can finger the insensate water period into his ass making it expand. After a instant he can experience his belly originate to amplify 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 brown runny shoots out of his ass and onto the base. It feels really Weird having the liquid shoot out of Matt 's ass. He then proceeds to put the clyster tube back in

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

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

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

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

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

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

The man then presses a button on his remote and the straps holding his hands and legs to the ground tighten and he is lifted up into the air on a weapons platform that he was on that he had not noticed before. The program stops at the stark height for the knight to riddle his ass. The entire then rears up and seat both its hooves on a bar so that the hooves will not be on lustrelessness. Then the stallion starts to squeeze searching for his hole. Matt starts to prepare himself for the inevitable. Finally after four or five missed thrusts, the cavalry finds his hole. At inaugural the buck can only fit the Malus pumila sized tip of his cock into his ass. The knight then begins to thrust his tool further and further into his ass. Finally, after a couple of minutes of the horse going deep and deeper into his ass the horse bottoms out and stands still for a couple of seconds. The annoyance 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 military action and then forms a invariable cycle. The botheration begins to settle and the pleasance kicks in. Before long he can feel his own dick starting line to shoot off on the trading floor. Then after ten min of heterosexual person fucking from the horse, he can finger the horse 's balls tense up. The buck then bottoms out and his tool erupts with cum. The hot fluid feels so effective inside his Virgo ass. The roofy 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 stops and right field as the horse pulls its tool 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 weapons platform and takes the straps off Matt 's leg and hands and he collapses on the ground. He feels so bloated and he looks at his stomach and it looks like he is pregnant from all the cum interior of him. He can sense it swishing around in his ass and it feels sort of in force. Then he passes out on the floor….

Matt wakes up on the coldness ground naked and looks at himself. His stomach bulged with all the cum interior of him and his ass ached and flatness tries to stand up but can not. He looks around and saw that he is in a horse horse barn. He then turns and looks at his twin baby lying next to him naked. She too had a stomach that bulged like she was pregnant too but she still looked aphrodisiac. lusterlessness could see her B-cup breast because she was lying on her back and her beautiful pussy with just a petty tuft of hair at the top of her cunt. His prick starts to grow but at that Lapplander import she woke up.

'' What happened '', proclaims Ally.

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

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

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

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

'' Rise and fall male child and girls '', the man says, `` I bet you have been wondering what the experimentation I
preformed on you was for. I didn't want to tell you yesterday to plunder the surprisal but here we go. Those 2 horses yesterday that you had a little fun with, were pattern. I genetically modified you and you sister to get impregnated by any creature. I also modified the time the pregnancy will use up to relieve oneself it go from 9 months to 1 month so you will find modification pretty soon. Another matter is that the reason I plugged up your holes from letting the cum seep out was because the creatures cum takes about 4 hours to saturate you. The reason I wanted to do this was because I wanted to produce the greatest horse ever. I could not do this with mating 2 horses together but I had to pair a horse cavalry with a human because with a human, the sawbuck can be very level-headed. The grounds I picked you 2 was because you both have high IQ 's, are athletic and it looked like you could wield this. And I thought it would be fun to have a brother and baby. 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… pregnant. ``

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

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

'' Well your eubstance will be changing to accommodate the foals but it will still hurt very much '', Dr. Jekyll
says, '' It will probably spite more than a convention pregnancy so be prepared. You will stay here in this stable for the remainder of this maternity. Oh, and one 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 plug out of
ally and says, `` Well I hope that this ejaculate 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 can.

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

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

Matt then lays on the ground in his puddle of cum, thinking about the events that happened yesterday. Then the man walks into the horse barn and says, `` Here 's dinner. ``

Then he walks out of the room. matte crawls over and gets the 2 bucketful and brings them over to friend.
friend gives mat a nonplused look 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 right '', says friend

She then tries the grain and agrees with Matt. They could have probably eaten anything at the minute.
They had not eaten anything in awhile and they were both very thirsty. They then took turn sipping body of water from the bucketful until the pail was drained. They then fall asleep on the inhuman concrete.

mat wakes up first the future first light and smell different. He feels a weighting on his chest and looks down and sees that he has some A-Cup mammilla. His articulatio coxae had widened too and his belly was a little bloated. His ass also did not finger 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 tits went from an A to a B-cup. He then hears a titter seed from his sister.

'' What 's so curious '', lusterlessness says to Ally.

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

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

'' Yeah '', ally says, `` The Equus caballus big cock felt so right in my twat. The best part was when he cummed, it
was so great that it gave me the best coming I had ever had. ''

'' Are those real ? '' friend says pointing to her buddy 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 hands on his teat. Matt was shaking in anticipation for this and lets out a pocket-sized moan as she places her hands on his tits and starts to experience around. ally then said to him, `` You can feel my tits if you want. ``

flatness then places his hands on his babe B-Cup tit. Ally too lets out a lowly groan 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 pap were the perfective size and they were still firm. lusterlessness then wanted to take it a minuscule further. He takes one paw off her tit and started to strike it down her organic structure. He reaches her clitoris and starts to rub it.

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

She then grabbed his already grueling cock and put it into her mouth. She started to give suck his turncock and massaging his balls at the Lapplander sentence. lustrelessness could find his sister sucking on his pecker, licking the tip every once in awhile. Then he could experience his balls tense up and he said to Ally, I am going to cum. '' Matt could then feel Ally start to deep throat his cock. mat then erupted with cum and then burgeon forth it all down his sisters throat.

Matt then took his cock out of his sis throat and picked her up and laid her in a recession on the hay. He then took his 8 inch cock and directed it into her awaiting puss. He pushed in slowly not wanting to hurt his baby. Finally after a little of pushing, he could feel his Ball rub up against her ass.

'' Are you set up '', asks Matt.

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

flatness then pulls out and mosh into his baby. He then started a cycle and he could feel the precum dripping out. His stopcock feels so good with his sisters pussy enveloping it. After what seems like an eternity, matt can feel his formal tense up and he goes hilt bass and cum into his Sister as hard as he can.

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

Dr. Jekyll had been watching the unit affair and was astonished. He had never thought that this would pass off. He then said, `` bravo you two. That was quite the show. ''

flatness and friend both blushed as they both thought about what just happened. What made it even worse was that someone had seen them do it. Matt then pulled his semi backbreaking shaft out of his Sister pussy and a picayune current of cum followed after that.

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

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

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

lusterlessness watches as his sister takes the huge horse tool and sticks it in her back talk and starts to nurse on it. matt then watched as she took her hands and started to jacklight off the knight monolithic tool. Soon he can see the horses balls tense up and he knew what was going to encounter. He could see her struggling to swallow the massive amounts of cum from the Equus caballus but soon he could see that she couldn't take it any more so she pulled the gymnastic horse cock out of his sassing as it was still cumming and it cummed all over her midget body. This turned mat on very a lot and soon he had a big fuckup watching the horse cum all over his babe.

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

matte had not been thinking about what was about to fall out. He walks over to his brown gymnastic horse and starts to rub its pecker. Soon the cock is at full duration and flatness 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 hale tool and puts it into his mouth. He starts to wet-nurse on it at the like time jacking off the knight with his hands. flatness loves sucking the horse cavalry cock. He can try the precum oozing from the horse slit and he loves it. Soon the buck balls tense up and beam ropes of cum down lustrelessness 's pharynx. Before long lustrelessness 's tum is good and he pulls out the cock from his mouthpiece. The horses dick then starts to film cum all over matt 's body covering him from head to toe.

Dr. Jekyll then walks into the room and says to the Twins, `` Oh, you two are a tidy sum, go back to your stable. '' Matt and friend comply and follow them back to their unchanging. He then puts a pail of frigid water and a sawbuck skirmish and says to them, `` You two should probably scavenge up. ''

They then grab the bucket and begin to scrub each former with it focusing on the `` sensitive '' expanse mostly. This routine goes on everyday for a duad of weeks. They wake up, have sex, get covered in cum, and then wash off each other. Their trunk go through many More changes as well. Both of their rosehip get wide enough to suit the horse. There tits swell up in size too. They go all the way to the D-Cup and kibosh. Their stomachs celebrate expanding rapidly in size of it too. With about a week leftfield, it looks like they are both having 4 in their abdomen. They have to blockade having sex because their bellies are so big but they can still feel each former up.

Then one day, Dr. Jekyll walks in the room with a box to the full of dildos. He says to the twins, `` Here, these are for Matt. If you want to drive home this buck without any damage then you will ask to work on making your rectum big enough to reconcile this horse."

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

'' You should be very well, women are meant to give nascence and I think that your vagina will do just fine. ``

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

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

'' trusted '', Ally says, `` Now get into the situation. ''

matt gets on his hands and genu and friend chooses the smallest dildos and penetrates flatness 's ass slowly. Matt moan because he had been craving having the cavalry dick in his ass for awhile but he knew that it would pain the foal. She then worked her way up to the gravid dildo which was as encompassing as the horses putz. She did this every day until one day mat had some tart pains in his stomach and soon after his sis did too.

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

Dr. Jekyll then came running in and says, `` The appearance has just begun '', and brings a president over to learn the festivities. They went through muscle contraction after muscle contraction together until 12 60 minutes in, Matt felt that he needed to push. He started to crowd and could feel the sawbuck sliding down his El Salvadoran colon. He pushed and pushed until he looked back and could see the head out. `` Almost there '', lustrelessness thought. The botheration was excruciating. He kept pushing and pushing until the breast stage popped out, then the back stage popped out after and he was done. His foal crawled over to him and mat pulled off the tissue layer from around it. The sawbuck then started to suck on mat 's tit. The feel 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 '', Matt says encouragingly, `` nigh there. ''

Matt can see the head start to come up out of his sisters pussy. ally keeps pushing and soon the movement legs pop out and finally the dorsum pegleg. friend sighs as her foal finally comes out. The two Gemini then fall asleep with their babies sucking on their tits.

They wake up the next day and they both feel different. Their body had gone back to normal. Matt no longer had nipple and widened hips and ally bosom and hips had gone done in size as well. They were perplexed. Then they could get wind the b threshold clear and in walked Dr. Jekyll into their stall.

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

He looked at their perplexed looking at and says, `` There was one more thing that I did not tell you about when I modified your organic structure. After you give parturition, the changes that were made revert back and you look just like you did a month ago. Unless you want to save the modification. ``

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

'' Ok, I bet you have been wondering what your parents are going to mean 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 letter of the alphabet 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 early, with a horse, and giving parentage. Are we clear ? ``

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

flatness had gotten so secondhand to be naked all the time that the dress feel weird. They then look at each former and Matt knows that life-time will never be the same .
