Jess attempted to cradle Jame’s head in her lap which was more difficult than it had been. she had to reach around her gigantic boobs it effectively shortened her arms. She effectively ended up smooshing his head into her sensitive teats on her belly.
“I’m sorry sis I didn’t mean it.” said Jess
Jess didn’t reply Well he wasn’t wrong I am becoming a cow and I do love my toys...heat and dampness was growing in her between her legs again. NO! Jess thought she shut her eyes and shook her head and took a deep breath to clear the thought away. Instead of fresh air though she got a nose full of musky cum smell that acted like a bellows to a fire. in addition to the warm heat growing between her thighs she noticed a cold wetness seeping through the legs of her dungarees.
Opening her eyes she realized two things James was laying in a huge puddle of (his own? she imagined her brother’s cock shooting gallons of seed NO! STOP!) cum. She was kneeling in the same puddle.
“Bro we’ve got to get out of here! Out of this.” she also realized that by scooping her brother into her lap she had coated her hands in musky spunk.
James closed his eyes against his tears. He loved his sister so much and after all that she had come to find him. Turning his head slightly James could feel his sisters teats gently prodding his face through her blouse. Just below the reek of donkey cum he could smell his sister’s (is it a cow pussy now? GAH! STOP thinking about your sister like that!) sex dampening. His horse dong started to stir NO he had to keep focused.
“I don’t think I can walk on my foot” James said opening his eyes.
“Lean on me! I’ll help you.” his sister replied while trying to hoist her brother. when she looked at him his eyes were widely staring at her head.
“yes, my ears, I know. Lets go!” with that last word she heaved him up on to his good foot and they started hobbling home i mean towards the cabin.
They moved in silence for a wile except for grunts. concentrating on the path ahead and keeping James from stumbling. Kept their minds off of of other things, mostly. but they were fighting the musk of the cum soaked clothes.
Jess’s ears retreated nearly to their human form but would grow out again with unbidden thoughts, or she caught sight of her brothers shirt bulging from what she could only assume was his fat horse cock. every lurching step caused her sagging breasts to swing around in her blouse. the teats of her breasts were banging and rubbing on the teats sticking out from her belly. All that flopping around was a constant reminder that she was becoming a fat stupid cow. Only good for milking and breeding. she wondered if any of the cum from the puddle had soaked into her panties. One of her ears brushing her shoulder snapped her out of it.
James was having a harder time. His sister’s ears growing and shrinking plainly showed her struggle with desire for him. She wanted the hardening horse cock flopping around in his shirt. She was fighting her desire to be bread by him. NO she is my sister! uhh baseball, yeah. He tried to think about baseball but it turned into a fantasy of pushing the bat into a his sisters meaty pussy. Suddenly he was noticing a strange dampness between his thighs. “nononononoNO!” shouted James..
“NO AAAAH STOP THINKING ABOUT SEX!” shouted Jess at the same time.
she shook her head violently she smacking her own face as well as her brother with her long ears.
With all the shouting and the shaking they weren’t looking where they were going and tripped. Jess landed with her face against the broad tip of James’ cock with only his t-shirt separating her from a mouthful of brothers dick. but this was the part of his shirt he had been saturating with his precum for the last several minutes and now her nose and mouth were slathered in her brother’s musky fluids.
They both froze.
Jess breathed in the earthy scent for three breaths, licked the pre from her lips and then went back for more sucking it from her brother’s shirt.
James moaned at his sister’s ministrations of his dick through his shirt and started pulling it off.
Once free Jess marveled and the thick mottled beast-cock throbbing in front of her. she had no restraint left and started trying to fit the head of this monster in her mouth. She shoved her tongue in his dickhole lapping up the copious clear fluid as soon as she could reach it.
She unbuttoned her dungarees and worked them free with one hand so she could get at her pussy.
Just then she heard a twig snap. She popped off of her brother’s mushrooming cock and turned to see a large dog standing behind her.
“Uunnnhhhg so close” said her brother full of frustration.
If he comes he will lock in what ever change he has. Jess suddenly felt very vulnerable. “We need to sto-MPHM!” She said as her mouth was filled. Her brother was so far gone he grabbed her by her ears and dragged her head back to his horse cock. He was no face fucking his sister and using her cow ears as handles.
Jess was terrified but a small but rapidly growing part of her was excited to be used as she should be.
A second shock came when she felt someone lapping at her dripping cunt. That dog! was the last thought before a sudden orgasm wiped all thought from her mind. She screamed as best as she could while being gagged by her brother’s dong. The lapping suddenly stopped as she was coming down. She felt the dog on her back as he started to hump at her pussy missing several times before burying his cock in her.
The stray dog is breeding me i’m just a cow only good for breeding and milking. she thought.
The head of her brother’s cock flared as jets of cum were fired down her throat.
“EERRRRGHEGEHA!” Said James
So much of her brother’s seed was being shot in to her that she coughed and couple of shots came right out of her nose.
breeding and milking she thought
Her stomach felt full and bloated.
breeding and milking...
Realizing his sister was struggling he lifted her off his cock which continued to glaze her face and chest.
Jess’s nose and mouth were completely filled with cum she was coughing and burping her brother’s cum even as she was grunting and moaning from the dog currently breeding her.
breeding and milking is all I am good for...
The dog continued his assault on her pussy. she timed her chant to his thrust
milking
and
breeding
and
milking
and
breedingggggggaahhh!
Jess came again.
she realized her blouse had popped open and her boobs were starting to fall out so she pulled at it. buttons flew as her breasts flopped free her teats dragging one the ground.
His rapid thrusts were causing her belly to jiggle more and more but she didnt have a belly? Jess reached back with one hand and found a large fleshy udder!
At the same time the dog slammed home his knot. but it didn’t stick inside her. It kept swelling and just kept popping in and out. She opened her eyes to see her brother watching her breeding with a stray dog.
While all this was happening James was lay on his back stunned from the longest orgasm in his life. Slowly processing everything he could not believe how much cum had come out of him...into his sisters face. Jess! what had he done to his sister...again. He raised his head to look at her and beg her forgiveness.
His eyes and quickly realized two things. His sister was looking at him while being fucked by a large dog and he had to do something about it. Just as he was crawling over to get the dog off of her she moaned out in orgasm.
Before James could do anything the dog dismounted and wandered off. James noticed the dog had a cunt between it’s ass an balls.
James looked at his sister. Her pussy was big before but now it clearly belonged on a cow. It had moved further back and the skin around her pussy was now black, rubbery looking and gaping open dripping dog cum. Her little butthole was now large and puffed out like a black donut right below her tail. between her legs was a large veiny udder caped with long teats. Her large pillowy breasts dragged on the ground but also looked...full. despite himself the scene before him started his cock to stir again and a strange wetness between his legs. He shot a hand down there only to be met with the damp velvety folds of a horse pussy! it felt so welcoming and-nonono!
James had not realized that he had closed his eyes.when he opened it he realized his sister was sobbing.
Even as aftershocks shot through her body she could feel her udder swinging and her tail swishing. she didn’t want to be a cow. With some difficulty she sat up and tried to get her brothers cum off her face and out of her nose. James’s arms were around her in a hug. her brother holding her brought out all the tears.
“I dont want to be a cow just breeding and milking! lookatmeimamonster!” she sobbed continuing to wipe at her face.
James had no idea what to say he had never been good at this sort of thing and how do you comfort someone who is turning into a cow?
“you are not alone.” was all he could think to say.
After a few minutes she stopped crying and dried her eyes on the ruins of her blouse.
she looked down at her massive breasts blue veins running all through them. beyond that was her lap filling udder. She put her hands on it. It was sore and sensitive. she banished thoughts of milk before they could fully form.
“At least we are not alone.” she hugged her brother warmly.
“Well, I don’t have to worry about finding pants again.” she joked as she hefted her milk bag.
James smiled wryly. then she sneezed. spraying semen all over james.
“I hope i didn’t get your nose pregnant.” James joked.
They both smiled.
James stood up before he remembered his ankle was messed up from the fall. but it didn’t hurt.
“Hey my ankle is all better” he shook it to be sure “It must have gotten healed by the transformation.” he said
“What else changed?” Jess asked
James was suddenly ashamed. Then he realized he had just cum all over his sisters face and watched her get fucked by a dog.
“I...have a horse vagina...and probably a butthole too”
he could feel his large donut between cheeks.
“I always wanted a sister.” Jess asked with a smirk.
James blushed.
“...no.”
Jess was going to ask to see it when she realized it was literally the worst idea. instead she looked around to get their bearings she could just make out the cabin in the distance. she was excited to get home until she realized that her clothes were beyond repair and she was coated in semen inside and out. As she stood up more dog cum slid out of her pussy and down her leg.
“bro I am going to need to hose off and get dressed before I see mom and dad. look in the closet in our room there should be a dress big enough for me.” with that she shuffled out of the rest of her clothes except for the sandals on her feet.
“I know being naked isn’t the best thing for maintaining our humanity but please try not to fuck me between here and the cabin.” said Jess.
James replied “I promise to try not to fuck you before we reach the cabin.” holding up a scout salute
“Also I think you should know about mom after....our...our first time I went to talk to mom and she already has a goat penis and hooves. Her and dad have been alone in the cabin for a few hours now.” said Jess
“You think there will be more changes to mom.” said james wearily.
“ Probably and maybe dad too. You and I can’t resist each other for long and we wouldn’t have sex normally. They would, and have and probably still do. Just be ready.”
James nodded and they bravely headed off towards the cabin.
At least they tried to. James could now walk normally but Jess had to figure out a waddling shuffling gait to avoid kneeing herself in the udder each time she took a step. Once she figured that out they made good progress.
Until Jess realized she needed to pee. the instant she felt the need her tail reflexively raised and huge amounts of pee came pouring out of her in a thick stream. She was so shocked that she had no control over it. urine was spattering on the grass for a few seconds before she thought to squat. she was still trying to control it until the stream dribbled out. even with all her and James had been through loosing control of her pee deeply embarrassed her and her ears drooped.
“I couldn’t control it!” Jess squeeked
“New muscles down there I guess”. James said calmly trying to sooth his sister
Jess stood and tiptoed out of the puddle of her own pee. I’m not toilet trained...or is it house broken? Will my poop just fall out of me? she thought.
As they neared the cabin there were lights on. There was a barn behind the house they hadn’t noticed before.
“I hate this place” said Jess
“Me too” said James
