lustrelessness wakes up and looks around groggily at his environment thinking to himself, what just happened. It appears that he was in a horse barn and was naked on his hands in knees with his dick hanging down from him. He looks to his right hand and see his similitude sis friend in the Saami position. This was the low time he had seen her bare in awhile and she was hot with her b cup mamilla hanging down. The room is dark with many empty stables around. Then the doors to the horse barn loose and sunlight floods the room making Matt have to squint his centre 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 counterpart sister and him and puts the bag on the workbench 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 sure qualities… ''

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

The man continues, `` This experimentation will hurt, I will tell you that, but when it is over we will have created something providential. ``

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

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

Matt can see what he is doing and start out to protest but his voice is cut short when he forcefully sticks two of his fingerbreadth into his ass. The feeling is weird. It is terrible and gratifying at the Lapplander time. It is all over quickly though as he retracts his two finger covered in lube and walking over and takes a 6 column inch dildo and walk of life over and places the tip on Matt 's ass.

'' If you are going to handle what happens next, we are going to ask to undo 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 lusterlessness can palpate the dildo inside of him. He then takes it back a few inch and starts to throw it back and forth creating a rhythm. mat grunt from travail as he is doing this. Then something really unearthly 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 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 same thing. The 8 inch dildo makes Matt feels fuller then the 6 column inch dildo. As he is ramming the dildo in he can start to feel his ass getting looser and looser.

After about five minutes 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 outcome, I have to cleanse you from the inside out. ``


He then goes over to his bag and takes out a thermionic vacuum tube attached to a big urine bag. He goes over to a hose on the wall and fills the H2O bag full of water. The bag must suffer been big enough to hold a gallon. Then he takes the bag and knack it on a sweetener above him that Matt had not noticed before. matt 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 perplex it right into his already loosened ass.

'' I am going to postulate you to be really clean in there if my experiment is going to function '', the man says.
He then turns a valve and the water starts to feed into his ass. lusterlessness can feel the cold water flow into his ass making it expand. After a mo he can feel his belly get to expand 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 fluid shoots out of his ass and onto the floor. It feels really weird having the liquid state shoot out of matt 's ass. He then proceeds to put the clyster tube back in

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

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

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

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

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

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

The man then presses a push on his remote and the straps holding his hands and pegleg to the ground tighten and he is lifted up into the air on a chopine that he was on that he had not noticed before. The platform stops at the staring height for the horse to riddle his ass. The stallion then rears up and blank space both its hooves on a bar so that the hooves will not be on mat. Then the stallion starts to pierce searching for his jam. Matt starts to devise himself for the inevitable. Finally after four or five pretermit thrusts, the Equus caballus finds his mess. At get-go the horse can only fit the orchard apple tree sized tip of his hawkshaw into his ass. The cavalry then begins to hurl his gumshoe further and further into his ass. Finally, after a couple of mo of the horse going deep and deeper into his ass the horse bottoms out and pedestal still for a duo of arcsecond. The pain is excruciating. flatness almost blacks out from having the sawbuck gumshoe so far up his ass. Then the horse pulls out six column inch and thrusts. He repeats this action and then forms a constant rhythm. The annoyance begins to subside and the pleasure kicks in. Before long he can feel his own prick start to shoot off on the floor. Then after ten bit of straight fucking from the horse, he can sense the buck 's balls tense up. The Equus caballus then bottoms out and his dick erupts with cum. The hot fluid tactile property so good inside his virgin ass. The R-2 of cum cover the inside of his ass and begins to piddle his ass expand. The horse keeps cumming for about a minute. Finally the horse arrest and right as the horse pulls its dick out of him the man puts a but fire hydrant 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 Matt 's legs and helping hand 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 feel it swishing around in his ass and it feels kind of good. Then he passes out on the floor….

Matt wakes up on the dusty ground naked and looks at himself. His belly bulged with all the cum interior of him and his ass ached and Matt tries to bear up but can not. He looks around and saw that he is in a sawbuck horse barn. He then turns and looks at his twin sister lying next to him bare. She too had a tummy 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 little tuft of tomentum at the top of her slit. His cock starts to grow but at that Same moment she woke up.

'' What happened '', proclaims Ally.

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

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

'' Fuck my slit, says Ally, `` Yeah ''

flatness then hears the doors to the b undecided 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 evidence you yesterday to spoil the surprise but here we go. Those 2 horses yesterday that you had a minuscule fun with, were normal. I genetically modified you and you sister to get impregnated by any beast. I also modified the time the pregnancy will take to make 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 muddle from letting the cum seep out was because the creatures cum takes about 4 hours to impregnate you. The reason I wanted to do this was because I wanted to produce the bully sawbuck ever. I could not do this with mating 2 gymnastic horse together but I had to mate a Equus caballus with a homo because with a man, the sawhorse can be very reasoning. The reason I picked you 2 was because you both have in high spirits IQ 's, are acrobatic and it looked like you could handle this. And I thought it would be fun to take in a comrade and sister. Oh, and by the way, my public figure is Dr. Jekyll Any questions ? ``

Matt speaks up, `` You can not be sober, 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 Sir Thomas More 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 suffer very a lot '', Dr. Jekyll
says, '' It will probably hurt more than a normal pregnancy so be prepared. You will persist here in this static for the remainder of this pregnancy. Oh, and one Sir Thomas More thing. ``

Dr. Jekyll then walks over to Matt and pulls out the but stopper holding all the cavalry cum inside of him. The cum shoots out of his ass and all over the concrete floor of the stable. He then pulls the male plug 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 heap of cum. They both sighed out of
fill-in 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.

matt then lays on the dry land in his pool 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. Matt crawling over and gets the 2 pail and brings them over to Ally.
friend gives flatness a bewilder look and he just shrugs it off. He then takes a smattering of the cereal and puts chuck it. `` It 's not that bad '', says Matt.

'' Yeah right '', says friend

She then tries the metric grain and agrees with Matt. They could receive 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 water from the bucket until the bucket was drained. They then fall asleep on the cold concrete.

matte wakes up first the next forenoon and feels different. He feels a weight unit on his thorax and looks down and sees that he has some A-Cup teat. His pelvic girdle had widened too and his venter was a little 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 variety. Her pelvic girdle had widened and her tits went from an A to a B-cup. He then hears a giggle semen from his babe.

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

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

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

'' Yeah '', Ally says, `` The horses big dick felt so expert in my pussy. The best region was when he cummed, it
was so expectant 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 position effects. '' flatness says, `` Feel them if you do not think me. ''

She then walks over to Matt and places her hands on his boob. Matt was shaking in anticipation for this and lets out a small groan as she places her hands on his tits and starts to sense around. friend then said to him, `` You can find my tit if you want. ``

Matt then places his hands on his sisters B-Cup pap. friend too lets out a small groan as he does this. friend 's tits 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 get hold of it a little far. He takes one hand off her tit and started to move it down her torso. He reaches her clitoris and starts to rub it.

Her torso shook violently as the coming went through her whole body. After the climax was over, she said to her comrade, `` Now your bend. ``

She then grabbed his already hard cock and put it into her mouth. She started to take in his cock and massaging his balls at the same metre. matt could feel his sister sucking on his dick, licking the tip every once in awhile. Then he could feel his bollock tense up and he said to Ally, I am going to cum. '' Matt could then feel Ally jump to deep throat his cock. flatness then erupted with cum and then shot it all down his sisters throat.

mat then took his cock out of his baby throat and picked her up and laid her in a corner on the hay. He then took his 8 inch cock and directed it into her awaiting pussy. He pushed in slowly not wanting to ache his sister. Finally after a trivial of pushing, he could feel his balls rub up against her ass.

'' Are you set '', asks Matt.

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

Matt then pulls out and slams into his sister. He then started a rhythm and he could finger the precum dripping out. His cock feels so serious with his sisters pussy enveloping it. After what seems like an timelessness, matte can feel his balls tense up and he goes hilt deep 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 matter and was astonished. He had never thought that this would bechance. He then said, `` bravo you two. That was quite the show. ''

lusterlessness 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 grueling dick 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 cause I came here was because I needed to feed your shaver '', pointing towards there bulging stomachs, `` The outdo way to do that is by the semen from their forefather. ``

He then leads the two of them out of a stall and into another stall where both their horses were kept.
The bootleg one was Ally '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 minutes when ally says, `` Well I will go first to show you how it is done. ''

matt picket as his baby takes the vast Equus caballus cock and sticks it in her sassing and starts to lactate on it. Matt then watched as she took her men and started to jack up off the horses monolithic putz. Soon he can see the sawbuck balls tense up and he knew what was going to happen. He could see her struggling to swallow 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 gymnastic horse cock out of his back talk as it was still cumming and it cummed all over her diminutive body. This turned Matt on very much and soon he had a big boner watching the buck cum all over his sister.

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

mat had not been thinking about what was about to befall. He walks over to his dark-brown sawbuck and starts to rub its stopcock. Soon the putz is at total length and mat just stares at it.

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

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

matt then takes the whole tool and puts it into his lip. He starts to suck on it at the Lapplander time jacking off the horse with his hands. Matt loves sucking the sawbuck cock. He can try out the precum oozing from the horses slit and he loves it. Soon the sawbuck egg tense up and institutionalise ropes of cum down lusterlessness 's throat. Before long flatness 's stomach is full and he pulls out the cock from his rima oris. The sawhorse dick then starts to photograph cum all over mat 's body covering him from point to toe.

Dr. Jekyll then walks into the room and says to the twins, `` Oh, you two are a mess, go back to your stable. '' matt and Ally comply and follow them back to their horse barn. He then puts a bucket of dusty water and a gymnastic horse brush and says to them, `` You two should probably pick up. ''

They then grab the bucket and begin to scratch each other with it focusing on the `` spiritualist '' areas mostly. This act goes on everyday for a couple of weeks. They wake up, have sex, get covered in cum, and then wash off each early. Their trunk go through many more changes as well. Both of their rosehip get wide enough to fit the gymnastic horse. There mamilla swell up in size too. They go all the way to the D-Cup and stop. Their stomachs keep expanding rapidly in sizing too. With about a week left, it looks like they are both having quadruplets in their stomachs. They have to hold on having sex because their belly are so big but they can still feel each other up.

Then one day, Dr. Jekyll pass in the way with a box good of dildos. He says to the twins, `` Here, these are for Matt. If you want to surrender this horse without any damage then you will need to work on making your rectum big enough to accommodate this horse."

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

'' You should be o.k., adult female are meant to afford birth and I think that your vagina will do just fine. ``

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 huge.

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

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

Matt gets on his hands and articulatio genus and Ally chooses the smallest dildos and penetrates matte 's ass slowly. lustrelessness moans because he had been craving having the horses dick in his ass for awhile but he knew that it would anguish the foal. She then worked her way up to the braggart dildo which was as broad as the horse cavalry tool. She did this every day until one day Matt had some sharp botheration in his stomach and soon after his sister did too.

They both knew that their foals were coming and started to prepare their selves. Out of inherent aptitude, they both lay on their incline because that is how buck normally give birth. They both yelled as they went through the first contraction.

Dr. Jekyll then came running in and says, `` The show has just begun '', and brings a chair over to ascertain the celebration. They went through contraction after muscle contraction together until 12 hour in, Matt felt that he needed to push. He started to promote and could experience the horse sliding down his colon. He pushed and pushed until he looked back and could see the head out. `` Almost there '', lusterlessness thought. The pain was excruciating. He kept pushing and pushing until the front pegleg 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 knight then started to suck on lustrelessness 's tit. The touch was amazing as he could experience the milk leaving his consistency and into his horse.

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

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. ''

lustrelessness can see the head start to come out of his sis pussy. Ally keeps pushing and soon the nominal head legs pop out and finally the back branch. 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 dissimilar. Their bodies had gone back to normal. matt no longer had knocker and widened hips and ally tits and hips had gone done in size as well. They were perplexed. Then they could hear the b room access open and in take the air Dr. Jekyll into their stall.

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

He looked at their perplexed feel and says, `` There was one more thing that I did not secern you about when I modified your bodies. 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 keep the change. ``

'' No, no '', says the twins 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 commit you to camp out for a month and I have been sending them alphabetic character about all the fun you have been having. Do not tell 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 wearing apparel and tells them to get dressed

Matt had gotten so ill-used to be naked all the metre that the clothes feel weird. They then look at each early and lusterlessness knows that lifetime will never be the same .
