Ashley decided to check upstairs for her sister and tip-toed up the staircase. As she neared the top she could hear a low moaning sound, very deep, but getting louder. Upon reaching the top of the stairs she called out for her sister once more but received no reply. Ashley looked down the hall towards where the noises were coming from and saw a door, slightly ajar, which she assumed was a bedroom, and given the use of this house it was likely some porn filming going on. Regardless, Ashley felt something very off in her bones, and was willing to risk some further embarrassment if it meant her sister might actually be in danger. She crept towards the door and gently placed her hand on the knob, pushing the door open just a bit further to see inside.
In the master bedroom, sprawled across the bed, was a woman with four large breast, the nipples extending several inches out, a white tail with a black tasseled tip flailing around behind a plump rear, a large bovine snout, two cow-like ears, and covered head to tow in white fur with black spots, was rubbing her sex with one hand while squeezing a stream of milk out of her teat with the other. Ashley was expecting something sexual but not some kind of anthro woman. After rubbing her eyes to see if she was imagining it Ashley found that not only was it real, but the figure seemed familiar in a way.
Ashley pushed the door open slightly further and stepped in, getting a closer look at the cow-woman. When she was only a few feet from the bed she could clearly make out her face and, aside from the snout, it was all too familiar.
“Laura?!” Ashley gawked.
The cow girl was broken from her trance and turned to her sister. “Ash!” the woman cheered. “I was worried you wouldn’t come after my message. Don’t worry though, everything is fine; better than fine.”
Ashley stood back, dumbstruck. “What the fuck happened to you?”
“Well, when I like, came out of my dressing room I found this cute girl waiting for me, totally naked, and she looked kind of like a bunny. She kissed me real quick and I just went with it, thinking it was just some super realistic costume and junk; but the more I kissed her the better it got and before I knew it I was this sexy bimbo.”
“You turned into a cow girl?!”
“Yeah, and it feels so nice when I get milked, especially by someone else.” With those last words Laura winked at her sister and Ashley was completely caught off guard.
Not only was she just looking at her sister masturbating, but she had turned into an anthro cow woman. To make matters worse, Ashley looked down at Laura’s teat to see it still leaking milk. She was still thirsty from before, and the milk looked so tantalizing.
“You want to try some?” Laura asked, Ashley’s jaw agape.
Without more than a moment’s hesitation Ashley pushed her sister back onto the bed and latched her lips onto the leaking teat. Ashley began to suck while Laura mooed from the pleasure. Ashley’s hands were squeezing Laura’s breast harder to get more milk out while Laura’s hands pressed her sister’s head further into her breast. Laura moaned to the sky and then looked down at her sister. Ashley’s hair was beginning to part on either side as two cow ears poked out from the top of her head. A tail began to stretch from her spine, wriggling it’s way out of her shorts. Soon Ashley was moaning at the pleasure of the experience into Laura’s breast and felt her own grow. An odd sensation started as she felt flesh build up just bellow her breasts as two new ones started to grow. While Ashley’s chest expanded so did her hips and ass, soon ripping the fabric which contained them. Her toes started to reshape into a solid hoof, while her fingers formed three hoof like digits. Soon all that was left of her clothing was her top, which was straining her from the new and improved breasts. Ashley sat up and ripped her shirt open, revealing to her sister the final steps of the transformation. Ashley’s face had already grown into a snout, and light brown fur was already covering most of her torso, expanding outwards. As the fur grew to reach her back it began to darken in spots, leaving her fully coated in less than a minute. Laura stared at her cow sister and then looked at her breasts which began leaking milk.
“Mmm, I’d like to try some of that,” Laura said as she latched onto her sister’s teat with her mouth.
Ashley moaned to the ceiling and it quickly turned into a deep moo. Soon the sister’s were suckling from each other’s breasts all throughout the night, and were content with all the milk they could desire. Eventually though, they might want to find another friend to join them.
