Have a cow

Jake came to with his hands bound and his mouth gagged in a closet. He was trying to remember how this had happened, then his memories came roaring back into his brain. He had been doing a routine check on the bovine potion earlier when two guys had jumped him from behind and restrained him in an instant. Jake had been told by on of the intruders that the potion was cruelity to animals, they were obviously animal fanatics, they also said that they were going to make him drink every last ounce of the stuff, all two and a half gallons of the stuff, after wards they gagged him and stuffed him in the closet. Jakes belly was still bloated from having drunk so much, "Got to get out of here..." he thought, "Nobody to helo me tonight....no other security personal in this sector." So Jake slowly began to work his hands free, he finally got the rope off after a few minutes, he had no idea what the potion would do to a human, but he did know that is made any mal bovine grow a little bigger, multiply its seed production by four, and cause the penis to enlarge enough to handle the new sperm supply. Jake really didn't want to be put in a lab so he hurridly laft leaving a note saying that he had knocked over the jugs containing the potion and had cleaned it up, the note was signed saying that he was sorry.

When Jake arrived at his small house his skin felt like it was on fire! Jake stumbled to his bathroom ignoring the burning feeling, his bladder needed to release alot of liquid, his stomach was still very bloated and his jaws were sore from drinking the potion. He unzipped his pants and pulled out his shaft. It was a good sized cock for a human, but it was nothign compared to a bovine cock, slowly a stream of urine poured out. However Jake noticed that his hand wasn't going all the way around the organ, usually his middle finger and thumb just barely touched each other now they weren't touching at all. He figuered that the poton caused this growth and continues using the bathroom, all the while letting his mind wonder about the secret stash of PlayBoy magizines under his bed, those pictures of naked women with huge tits aroused him greatly. He had finished peeing but his cock was growing hard as it pushed its way out of the sheath. The hard shaft slithered through his hands, when done growing his boner was bigger than a full grown bull cock! Then all of a sudden his balls began to swell to match the size of his new equipment. His balls grew to the size of a male cows testicles. His hand rubbed vigerously, making the preasure build within his enlarged member. With a moan that sounded more like a howl from an animal he cummed. The white liquid gushed out of the cocks tip and splatterd onto the floor. When the cloud of lust had left Jake finally took notice of his bigger dick, he had the biggest cock for a human, "Could this have happened from that potion? I wonder what else will happen?" Jake thought.

Jake stuffed his endowment back into his pants afted it had gone soft, he was walking towards the kitchen when he noticed that his legs were becoming stiff and hard to move, a tight feeling spread through out his body at a very fast pace. His pants were becoming extremely tight, his feet felt like they were in a furnace, so he bent down painfully and removed his shoes and to his shock his toes were fusing together into hooves! His pants were to a point were they felt like a vice, Jake undid the button with a little trouble but the zipper explodded as soon as the button was cleared. The pants tore along the seams as muscles grew, his butt puffed up a little and a spot at the base of his spine grew into a lump. The lump grew longer and sprouted hair at the end, Jake now had a cow tail. His shirt slowly ripped to shreds as his upper body gained muscle, his neck lengthened slightly, his face extended into a snout, and his nose grew to the average bovine size. He felt his jaw structure rearrange as his teeth became wider and thicker, his tounge grew much longer, but the biggest supprize for Jake was happening on his chest. A bulge had developed on the left and right side of his front torso, they quickly inflated greatlybefore his eyes, and before he knew what had happened, a set of gigantic tits had burst out of his shirt and each was equipped with four nipples, just like and udder! Jake was so much in shock that he didn't notice the short brown and black patched fur beginning to grow all over his new body, when his skin was completely covered in hair Jake was finally able to tear away his eyes from his udder tits and gaze upon his new form. The only thing he could think to say was, "HOLLY MOTHER FUCKING HELL!!!" he screamed with all his might in his new feminine voice. Jake was now part male and part femal, she wanted to change back into her human form but she didn't know if that was even possible. Jake slowly walked out of the kitchen, her udder tits jiggling with each step. She desperately wanted to go back to the lab and see sbout a cure, but how would the scientists react to the fact that she had drank all of the potion and how was she going to be in public without anyone seeing her?

There wasn't much choice for her at the moment since she didn't know if more changes were going to happen, she had to call them and tell the truth. Jake picked up the phone and began punching in the numbers for the Lab. Her friend Rick was the one who answered, "Hello, this is Rick. Can I help you?"

"Actually you can..." replied Jake, hearing the new girl voice Rick had no idea it was Jake speaking. "Who is this and how did you get this number?!!"

"Rick its me Jake..."

"Jake? What happened to your voice?"

"You'll find out later, but right now I need you to drive the van to the back of my house and try not to yell when you see me."

"Okay then, see ya there." and with that the line was disconected. While waiting for Rick, Jake went to her bedroom insearch of clothes to try and hide some of her bovine body, especially her udder breast. She pulled on some pants over her thickly muscled legs, having some trouble pushing her hooves through the legs. Jake also found a shirt that fit over her large tits but it just barely held them back. You could see the nipples under the stretched fabric, "At least they haven't grown bigger." she thought, her big cow cock also caused a slight bulge on the front of her pants. Then at last Rick drove up to her backyard, but not in the van. He was driving the truck hauling the trailer, Jake sighed heavily, "It will have to do." she thought, "Time to suprize Rick..." she mumbled as she headed for the backyard.

Rick was waiting for Jake at the back pourch but he didn't expect what was going to come out the door, the door opened and out stepped some kind of a cow/human hybrid!"Holy shit! What the heck are you?!" screamed Rick.

"Easy Rick its me Jake." replied a somewhat suprized Jake.

"Jake? What happened to you?!"

"I'll tell you and everyone else at the lab, but first I need to get there."

"Alright then, get in the trailer, I couldn't use the van." Jake walked over to the trailer and got in, but the smell on the inside smelled different, it stirred something within her. Rick started up the truck and began to back up and head off to the Lab. However the scent inside the trailer continued to do something to Jake, "Rick, what was in this trailer?"

"Just some male cows."

"Oh crap.." she thought when she heard his answer. She now knew what was going on, the musk of the earlier occupants was making her horny and very aroused. She could feel her cock begin to grow inside her pants and her tits start to puff up making her nipples hard and stiff. Jake tried to stop, but she failed. Moans escaped her mouth as she grew more horny, cum was leaking from both her cock and vagina and milk was coming out of her tits, she desperately wanted sex now. Loud groans came from the trailer, Rick knew what the noise ment, "Try to calm down Jake. We don't need anyone finding out about you.", Jake couldn't hear him. Another cloud of lust had enveloped her mind, her clothing had become soaked with the liquids leaking from her body, but her cock was slowly growing. It traveled down the pants leg, stretching the fabric her cock pulsed about hungry for a chance to be pushed deep into a rump. Her tits were also growing, they inflated more and more, her nipples widdened and grew longer. With a very load ripping sound her shirt and pants tore apart as her two body parts burst through the clothing revealing a gigantic set of boobs that were leaking milk and her lower regions were even more breath taking. Her shaft was five feet long and three feet wide, and at the base of her monsterous cock was a sac that hung limp, but very heavily with two huge balls inside it. Jake took her fingers and shoved them into her vagina, pulling them out and pushing them back in, trying to satisfy her lust. Her other hand was busy doing two things, messaging her giant udder breasts and then switched to rubbing her monster cock. Preasure grew inside her body, her body temperature increased, making her tounge hang out her mouth as she began to pant. Moans of plesure came from the trailer, the noise and smell of sex was having the usual effect on Rick, he was being aroused. A bulge had developed on the crotch of his pants, he groaned as he restrained himself from masturbaiting.

Rick picked up the pace so he could reach the Lab before the musk from the new Jake broke down the last of his self control. Jake on the other hand was enjoying the sensation of rubbing her big tits, causing more milk to shoot out from all eight nipples, the milk splattered onto the wall and dripped to the floor. Cum was gushing out of her rock hard member and vagina, the two liquids mixed together on the floor. The preasure inside her body was still growing and fast. Heat was pouring from all over her body in waves, it felt like she was in a heat box. Finally she cam, cum shot out of her cock like a broken fire hydrant, more cum was being pushed out of her vagina, and milk was being drained from her tits like they were water guns, each nipple having a solid stream of the white liquid. Quickly the floor of the trailer was covered in an inch deep layer of her cum and milk. When Jake was free of the lust she collapsed to the floor gasping for breath. "That was the biggest orgasm I've ever had." she whispered to herself, Rick on the other hand wsa still battling his own lust.

"Damn, I need to cum soo badly! Got to get Jake to the Lab first, only another five miles..." he muttered. He could feel precum leaking from his errection while Jake lay in her own juices as she calmed down, her cock slid back into her sheath and her nipples became soft again. After another two hours of torture, Rick at last reached the Lab. He swipped his ID card and drove the truck up to the loading ramp. Rick got out of the truck and went to undo the latch on the trailer, as soon as the door was swung open a small waterfall of Jake's juices cascaded out of the trailer and onto the ground. "For the love of god Jake! How in the world did you make all this?"

"I'll tell you and the rest of the workers once I'm inside." replied Jake. Lucky for Jake not a soul saw her new form, however when the people in the Lab saw her they had the same reaction that Rick did. Jake then told them all about the intruders and how they had forced her to drink the potion. The scientists didn't blame her for what happened to the potion or that she was scared to come for help at the start of it all. Jake was told to stay within sector six, lab # twenty-one, so as not to freak out the locals, Jake happily agreed.

Later Matt, another friend of hers, was taking a blood sample for tests, "So how does it feel?"

"This body feels like my old one except for the tail and tits."

"Interesting..." Matt thought as he finished drawing blood. Then all of a sudden two great bulges developed underneath her boobs, at least this time she was wearing a stretchy shirt, it was very fourtinate for her to be wearing it becuase the bulges quickly became a second set of udder tits which grew to match the size of the originals. Her pants weren't as lucky, her butt started to push out against the pants, the seams tore easily as he rbutt extended and the pants legs tore apart as another pair of hooved legs grew. Her bottom qucikly pulled away from her body forming a body of a cow where the head should have been her upper body was attached, she was a cowtaur. She even had another normal udder, her cock had grown bigger, it now reached five and a half feet long by four feet wide, and she could feel her balls swelling slowly.Her boobs all of a sudden had a last minute growing burst and explodded out of her shirt with milk dripping from all six-teen nipples and then a pair of horns sprouted from her forehead, and with that the changing was done.

"WHAT THE HELL HAPPENED TO ME!!!" screamed Jake.

"I-I don't know! My guess is that your body is still changing from the effects of the potion, there is no way I can tell if the changes won't or will happen again. To find that out I'll need to do some other tests. I'll be needing more blood."

"Fine, lets get this over with." mumbled Jake in misery. "Any idea what would have caused this?" asked Matt.

"I don't know, the last thing I did was a some what brief moment of playing with myself. I had been aroused by the musky scent of the earlier cattle that had been in my trailer."

"My guess is that every time your body undergoes that sensation you become more cow than human, not to mention that you aparently grow a new set of breasts everytime it happens. You should probably not do anthing to cause another change, and yes that includes playing with yourself Jake!" ordered Matt. "All right." said Jake, Jake left Matt alone so he could test her blood, to make the time go b yshe walked about the building's area, she knew most of the place, but since she wasn't going to leave the place anytime soon, she figured that she would look around. First she went to the East Wing, the East Wing was mainly storage. There were hundreds of doors, some locked, others weren't. Behind th first door was an old looking machine, there was a layer of dust on everything. Jake opened the door further to allow her lower body into the room. "Strange looking device, it kind of looks like a milking machine." she thought. But on a closer inspection she saw that it had needles on the ends of two arms, ":What the hell is this thing." she pondered out loud. There was a console attached to the side of the machine, Jake pushed the "on" button and the screen flickered to life.

As it turned out the machine had been designed to inject a breast expending horamone into female cattle in order to promote better milk for their calves, but the project had failed so the device was forgotten. There were a few pictures of the test subjects and all of them had tits so big their legs couldn't touch the ground! For some reason Jake pictured herself with such massive tits, the very thought of such big boobs arounsed the male side of her personality. Her ock slid out of her sheath, ready fo rattention. To bad for Jake was that since she was a cowtaur she couldn't her cock with her hands, so she began rubbing her own massive breasts. Jake knew she wasn't suppose to play with herself but she had allready been aroused by those pictures. Her cock inched forward more and more as she became more aroused. As her cock was growing so to was her balls, they swelled larger and wider, her sac dropped to the floor from the weight of her testicles. Milk was once again dripping from her tits, her tail swished back and forth, the preasure was building in her cock and tits. Soon her hind legs were slowly being lifted off the floor from the girth of her balls, they only got lifted about an inch into the air before Jake began to cum. Jake roared in pleasure as the force of her orgasm blasted cum across the room, milk also had shot out of her tits, more cum poured out of her femal sex onto the floor. As the preasure dwindled Jakes control over her body increased, "Damn, that was a new feeling..." she said to nobody. Jake could only hope that she wouldn't undergo more changes like last time.

After she turned off the strange machine, Jake walked out the door and carefully closed it behind her, she teh trodded off back towards the big room she now called home. Jake continued to think about machine, what would it be like if she had such titanic tits? As she was going towards her room, she felt a sensation in her crotch area, the feeling spread throughout her entire body, she galloped down to her room as fast as possible and slamed the door shut behind her and not a moment to late. Two bumps had formed under her lower level boobs, the bumps quickly inflated and developed nipples, a second udder grew on her belly, and her cock grew bigger, reaching a size of seven feet long by five feet wide. Her balls were hanging close to the floor and her sheath was just barely touching the floor! All six of her breasts inflated even more as they produced more milk inside, now no bra would be able to contain them. Her cock slowly extended towards her front legs, preasure began to grow inside her sac, but it didn't feel like an orgasm. Instead her balls were growing and they stopped growing when they hit the floor, "Motherfucker!" shouted Jake. Her legs then began to grow long enough to suspend her massive balls, but her legs wasn't the only thing enlarging, her whole body was growing to match her cock and tits. When the growing was finished Jake was absoulutely massive, her legs must have been at least seven inches thick! Her tail had also grown, it was slightly thicker but it was much longer, almost like a cats tail with very short fur. Her two udders were equally fat with milk and her three sets of udder tits were twice as plump as her normal udders, Jake walked toward her door so she could go back to the other labratory so she could show Matt what had happened. It seamed like she would never get her old life back. When Matt saw that she had undergone more changes his jaw dropped, "What the heck! Don't tell me... you played with yourself didn't you?"

"I couldn't help it, I saw some female bovine on some pics from an old gadget in the East Wing, and I got aroused." replied Jake.

"I guess I can't blame you for what nature caused, but from now on you'll have to be completly solitary, no more of your 'little' adventures." Even as Matt was going over every tiny detail of Jake's confinement, she was still thinking about that machine, a sort of make-shift plan was already forming inside her head. She would sneak away tonight and use that machine.

Late that night Jake was trying her hardest to keep her hooves from making too much noise, she was already in the East Wing. She was at the door of the failed project, Jake silently opened the door and trodded into the room. First she turned it on again and began to look over what she had to do, strangely though she didn't need to do so much except provide a strand of her fur and stand still. After Jake placed the hair on the DNA scanner the two mechanical arms came to life. The two robot arms extended forward and plunged themselves into Jakes top level tits, but since she had another two sets four more arms came out of the machine and they to plunged their needles into her tits. A pink fluid goo then began to flow through the hose on the robot arms and was pumped into her tits, as soon as the first doze of that goo entered her tits she felt her tits begin to swell in size and girth! She grabbed one of her three sets and felt them expand within he hands, when she looked down she saw them continue to grow beyond that of her hands could hold. Milk began leaking from her udders and tits, her breasts grew to the size of her body and Jake could only wnat more for them to be bigger. She didn't notice her cock begin to swell greatly, the sheath stretched across the tile floor, her balls became engorged with seed, her cock and tits stopped growing when the pink goo stopped flowing into her body. As it turned out the machine had used all of it up, "Damn!" thought Jake when she saw just how huge her tits and cock had grown. The milk that had leaked from her body was surrounding her like a good sized puddle. She had to get out of there before anyone saw her and fast! The only problem was that her hyper tits were now too big to pass through the door frame, he cock was equally titanic, a ten foot long by five feet wide god of a cock when it was soft! unfourtinately for her the sight of her hyper endowments was getting her aroused, her cock had already begun to grow hard, she felt it leave her sheath and push its way past he legs and shove its massive head into her cleavage. Jake then began to tit fuck herself and rubbing her hands all over her soft tit flesh. Preasure was building inside her tits and cock, "Oooohhhhh!!!!" moaned Jake loudly, her rear was doing the normal humping motion causing her cock to be pushed a little deeper into her cleavage. The sensation she was feeling was unforgetable and indescribeable, the preasure grew more and more as the seconds ticked by. MIlk and precum were leaking from her body, then the preasure reached it peak and she started cumming.

Milk and cum splattered onto the walls and covered the floor, everything weas soaked with the milky white liquids. When she was finished another suprize revealed itself, the door opened and in the doorway was Matt and a machanic!

"Jake!!! HOLY SHIT!! What the heck happended to you?!" screamed and outraged Matt, but when he saw the milky white liquids all over the room her had his answer, "I'll give you this shot, it will permenately stop the changes but it will also make it tougher to return you to your human form, so hold still." said Matt. The needle was poked into her arm just as that odd changing feeling was starting up but whatever was in the neeple made it go away. "I guess I'm stuck like this forever..." groaned Jake.

"Only untill we develop a cure for you 'condition'. However with so much milk stored in you udders you'll need to be milked dialy, I'll go get Jenny now, in the mean time, Arther will you please take apart that device so our friend here will never use it again."

Three weeks later Jake was finishing up her old routine checks, "Jake...its milking time." said Jenny from the doorway, "Coming..." replied a some-what happy Jake. Life wasn't so bad now, she woudn't miss her old life too bad now.
