lusterlessness wakes up and looks around groggily at his environs thinking to himself, what just happened. It appears that he was in a stable and was naked on his mitt in genu with his peter hanging down from him. He looks to his right and see his twin sister ally in the same position. This was the first time he had seen her naked in awhile and she was hot with her b cup mamilla hanging down. The room is morose with many empty stalls around. Then the doorway to the unchanging open and sunlight floods the room making mat have to squint his eyes to see what is happening. The threshold closes quickly and he can clearly see a man walking into the room with a big bag. He walks over to his Twin sister and him and puts the bag on the bench and starts to babble 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 '', mat pleads.

The man continues, `` This experiment will pain, I will secernate you that, but when it is over we will birth 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 lube and an assortment of dildos. He puts on a boxing glove and sticks his fingers into the lube.

lusterlessness can see what he is doing and set out to protest but his voice is cut short when he forcefully sticks two of his digit into his ass. The tone is weird. It is atrocious and gratifying at the Lapp meter. It is all over quickly though as he retracts his two fingers covered in lubricant and walks 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 future, we are going to need to loose 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 lustrelessness can find the dildo inside of him. He then takes it back a few in and starts to pierce it back and Forth River creating a rhythm. Matt grunt from exertion as he is doing this. Then something really weird happens, he starts to get a fuckup. He had never been gay in his animation 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 inch dildo and does the same thing. The 8 inch dildo makes matte tone fuller then the 6 inch dildo. As he is ramming the dildo in he can lead off 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 set, there is just one more thing I have to do to you to get you prepare for the main effect, I have to clean you from the inside out. ``


He then goes over to his bag and takes out a subway system attached to a big water bag. He goes over to a hose on the wall and fills the piss bag full of H2O. The bag must take in been big enough to curb a gallon. Then he takes the bag and hangs it on a claw above him that Matt had not noticed before. matte think he recognizes the bag from some of the smut he watched. It was an enema, he thought to himself. He then takes the tube and proceeds to adhere it right into his already loosened ass.

'' I am going to require you to be really clean in there if my experiment is going to make '', the man says.
He then turns a valve and the water starts to hang into his ass. flatness can feel the cold weewee flow into his ass making it expand. After a moment he can feel his belly startle to dilate 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 brownish fluid shoots out of his ass and onto the floor. It feels really weird having the liquid state shoot out of lustrelessness 's ass. He then proceeds to put the clyster tube back in

flatness '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 ready, bring him in. ``

flatness turns around and sees the room access to the b open and a man walks in directing a entire 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 pecker. Before long a 2 foot foresighted turncock outflow out from the horse.

Matt 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 clit on his remote and the shoulder strap holding his hands and legs to the undercoat 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 complete height for the horse to fathom his ass. The stallion then rears up and post both its hooves on a bar so that the hooves will not be on flatness. Then the stallion starts to throw searching for his hole. Matt starts to organize himself for the inevitable. Finally after four or five omit thrusts, the cavalry finds his hole. At start the horse can only fit the apple sized tip of his tool into his ass. The cavalry then begins to thrust his peter further and further into his ass. Finally, after a duet of second of the buck going deeper and deeper into his ass the horse bottoms out and stands still for a couple of seconds. The pain is excruciating. Matt almost blacks out from having the buck dick so far up his ass. Then the horse pulls out six inch and thrusts. He repeats this action and then forms a incessant rhythm. The annoyance begins to subside and the delight kicks in. Before long he can find his own hawkshaw offset to fool away off on the level. Then after ten minutes of straight fucking from the gymnastic horse, he can palpate the knight 's balls tense up. The horse then bottoms out and his dick erupts with cum. The hot fluid tactile property so good inside his Virgin ass. The forget me drug of cum cover the inside of his ass and begins to make his ass expand. The gymnastic horse keeps cumming for about a hour. Finally the horse stops and right as the Equus caballus pulls its dick out of him the man puts a but plug in.

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



He then lowers the platform and takes the shoulder 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 sort of good. Then he passes out on the floor….

mat wakes up on the cold-blooded reason naked and looks at himself. His abdomen bulged with all the cum inside of him and his ass ached and matt tries to stand up but can not. He looks around and saw that he is in a sawhorse stable. He then turns and looks at his twin baby lying future to him nude. She too had a abdomen that bulged like she was pregnant too but she still looked sexy. Matt could see her B-cup breast because she was lying on her back and her beautiful kitty with just a petty tuft of hair at the top of her slit. His tool starts to originate but at that Same moment she woke up.

'' What happened '', proclaims Ally.

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

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

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

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

'' Rise and strike 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 tell you yesterday to spoil the surprise but here we go. Those 2 horses yesterday that you had a niggling fun with, were pattern. I genetically modified you and you sister to get impregnated by any brute. I also modified the metre the pregnancy will conduct to make it go from 9 months to 1 month so you will feel changes pretty soon. Another matter is that the grounds I plugged up your holes from letting the cum seep out was because the creature 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 sawhorse together but I had to mate a knight with a human because with a human, the knight can be very intelligent. The intellect I picked you 2 was because you both have high IQ 's, are gymnastic and it looked like you could handle this. And I thought it would be fun to have a brother and sister. Oh, and by the way, my public figure is Dr. Jekyll Any inquiry ? ``

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

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

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

'' Well your trunk will be changing to accommodate the foals but it will still pain very very much '', Dr. Jekyll
says, '' It will probably hurt more than a normal pregnancy so be prepared. You will stay here in this unchanging for the end of this pregnancy. Oh, and one Sir Thomas More thing. ``

Dr. Jekyll then walks over to Matt and pulls out the but plug holding all the sawbuck cum inside of him. The cum shoots out of his ass and all over the concrete floor of the stable. He then pulls the wad out of
ally and says, `` Well I hope that this semen did its thing. ''

He then walks out of the stable leaving Matt and friend laying in raft of cum. They both sighed out of
relief 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 priming coat in his pool of cum, thinking about the case that happened yesterday. Then the man walks into the stalls and says, `` Here 's dinner. ``

Then he walks out of the room. matt crawls over and gets the 2 bucket and brings them over to Ally.
Ally gives Matt a amaze look and he just shrugs it off. He then takes a handful of the grain and puts eats it. `` It 's not that bad '', says Matt.

'' Yeah mighty '', says ally

She then tries the food grain and agrees with lustrelessness. They could birth probably eaten anything at the mo.
They had not eaten anything in awhile and they were both very hungry. They then took round sipping water from the bucket until the pail was drained. They then fall asleep on the cold concrete.

Matt wakes up first the next forenoon and feels different. He feels a weight on his chest and looks down and sees that he has some A-Cup tits. His rosehip had widened too and his stomach 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 alteration. Her pelvic girdle had widened and her tits went from an A to a B-cup. He then hears a giggle come from his sister.

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

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

'' Yeah '', Matt says, `` It hurt at 1st but after awhile it felt really good. ``

'' Yeah '', ally says, `` The horse cavalry big dick felt so good in my pussy. The undecomposed part was when he cummed, it
was so expectant that it gave me the best sexual climax I had ever had. ''

'' Are those existent ? '' friend says pointing to her brother tits.

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

She then walks over to Matt and places her helping hand on his tits. flatness was shaking in expectation for this and lets out a pocket-size moan as she places her hands on his nipple and starts to feel around. Ally then said to him, `` You can finger my boob if you want. ``

flatness then places his hands on his sisters B-Cup tits. 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 pap were the perfect size and they were still firm. lustrelessness then wanted to take it a little further. He takes one hand off her tit and started to go it down her soundbox. He reaches her clit and starts to rub it.

Her trunk shook violently as the climax went through her whole organic structure. After the orgasm was over, she said to her sidekick, `` Now your routine. ``

She then grabbed his already hard cock and put it into her mouthpiece. She started to suck his rooster and massaging his lump at the same time. Matt could feel his sister sucking on his shaft, licking the tip every once in awhile. Then he could feel his balls tense up and he said to Ally, I am going to cum. '' lustrelessness could then feel Ally start to deep throat his cock. Matt then erupted with cum and then shot it all down his sisters throat.

flatness then took his prick out of his sis pharynx and picked her up and laid her in a street corner on the hay. He then took his 8 inch putz and directed it into her awaiting slit. He pushed in slowly not wanting to hurt his baby. Finally after a little of pushing, he could feel his balls rub up against her ass.

'' Are you ready '', 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 experience the precum dripping out. His hammer smell so good with his sisters pussy enveloping it. After what seems like an eternity, Matt can experience his musket ball tense up and he goes hilt deeply and cum into his babe as hard as he can.

They both lay there for a few moment with lusterlessness 's dick still in his sisters pussy and that 's when they heard individual clapping.

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

Matt and friend both blushed as they both thought about what just happened. What made it even worse was that somebody had seen them do it. Matt then pulled his semifinal difficult cock out of his sisters pussy and a short stream 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 venter, `` The best way to do that is by the semen from their male parent. ``

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

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

mat spotter as his sister takes the huge Equus caballus shaft and control stick it in her mouth and starts to suck on it. lusterlessness then watched as she took her handwriting and started to jacklight off the horse monolithic pecker. Soon he can see the horse cavalry balls tense up and he knew what was going to happen. He could see her struggling to take back the monumental quantity of cum from the horses but soon he could see that she couldn't take it any more so she pulled the horses cock out of his sassing as it was still cumming and it cummed all over her petite body. This turned Matt on very much and soon he had a big boner watching the horse cum all over his sister.

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

Matt had not been thinking about what was about to happen. He walks over to his brownish horse and starts to rub its putz. Soon the turncock is at full distance 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.

matt then takes the whole cock and puts it into his mouth. He starts to suck up on it at the Lapplander sentence jacking off the horse with his hands. Matt loves sucking the horses turncock. He can taste the precum oozing from the horses slit and he loves it. Soon the horses balls tense up and send ropes of cum down lusterlessness 's throat. Before recollective mat 's stomach is full moon and he pulls out the cock from his mouth. The knight dick then starts to shoot cum all over Matt 's body covering him from school principal to toe.

Dr. Jekyll then walks into the room and says to the Gemini, `` Oh, you two are a mess, go back to your stable. '' Matt and Ally comply and follow them back to their stable. He then puts a bucket of cold water system and a Equus caballus brush and says to them, `` You two should probably clean up. ''

They then grab the bucket and get to scrub each other with it focusing on the `` sensitive '' areas mostly. This subprogram goes on everyday for a couple of weeks. They wake up, have sex, get covered in cum, and then wash each former. Their bodies go through many more changes as well. Both of their hips get wide enough to accommodate the horse. There titmouse swell up in size too. They go all the way to the D-Cup and stop. Their stomachs celebrate expanding rapidly in size of it too. With about a week left wing, it looks like they are both having quadruplets in their stomachs. They have to arrest having sex because their stomach are so big but they can still experience each early up.

Then one day, Dr. Jekyll walks in the room with a box full of dildos. He says to the twins, `` Here, these are for mat. If you want to give birth this horse without any damage then you will need to act on making your rectum big enough to accommodate this horse."

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

'' You should be hunky-dory, fair sex are meant to give nascence 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 post. ''

matte gets on his hands and human knee and friend chooses the smallest dildos and penetrates Matt '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 hurt the foal. She then worked her way up to the full-grown dildo which was as wide as the horses shaft. She did this every day until one day Matt had some sharp infliction in his tummy and soon after his Sister did too.

They both knew that their foals were coming and started to educate their self. Out of inherent aptitude, they both lay on their incline because that is how horse cavalry normally give nascence. They both yelled as they went through the first of all muscular 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 contraction after muscular contraction together until 12 hour in, Matt felt that he needed to push. He started to push and could feel the knight sliding down his colon. He pushed and pushed until he looked back and could see the head out. `` Almost there '', matte thought. The pain was excruciating. He kept pushing and pushing until the front pegleg popped out, then the back branch popped out after and he was done. His foal crawled over to him and lusterlessness pulled off the membrane from around it. The horse then started to suck on matte '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. ``

flatness 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 front legs pop out and finally the backbone legs. ally sighs as her foal finally comes out. The two Gemini the Twins then fall asleep with their babies sucking on their tits.

They wake up the next day and they both feel different. Their physical structure had gone back to pattern. matt no longer had tits and widened rose hip and Ally tits and rosehip had gone done in size as well. They were perplexed. Then they could get a line the barn room access open up and in walk Dr. Jekyll into their stall.

'' howdy '', Dr. Jekyll says to the Twin, `` You two did a gracious job yesterday. ''

He looked at their perplexed smell and says, `` There was one more affair that I did not enjoin you about when I modified your trunk. 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 back the changes. ``

'' 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 calendar 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 alphabetic character about all the fun you have been having. Do not recount anyone about what happened today unless you want me to give up a television documenting what happened. From you having sex with each other, with a horse, and giving birth. Are we clear ? ``

They both nod in correspondence. He then tosses in some clothes and tells them to get apparel

mat had gotten so used to be naked all the meter that the clothes feel Weird. They then look at each former and mat knows that life will never be the Lapplander .
