Cat soon finished pleasuring both herself as well as the donkey, and then laid back, almost in a daze while she continued to change.
Grrl stood and watched in both horror and amazement at Cat's transformation. She had removed her socks and shoes already, and her feet were just beginning to grow fur. Cat continued to remove her clothing while a warm feeling overtook her. Grrl noticed Cat's breasts, and how they began to swell.
Grrl no longer had any fear of what was going on, but was rather inquisitive. Cat removed her top and bra, freeing her growing breasts. She began to move her hands over her body, across her thighs and hips, her rump, and up across her waist, stomach, and chest.
"Oooohhhh," she moaned in pleasure as she moved her soft warm hands across her growing nipples. Much of her chest was covered in a dark, dense fur, that was rather soft, but her breasts were still visible.
A tail then began to grow from her lower back, just above her cute little rump. Cat slid her hands down to her waist, slowly pulling off her pants, and dropping them on the floor. Her vagina was completely covered in a very dense fur, which spread across her upper thighs, and around to her back side, completely covering her rump.
Grrl was pulled to Cat now, her transforming body acting like a beacon to a ship that had been lost at sea for years. She knelt down beside Cat, observing her mane, her fur, her breasts, her legs, her tail which was now fully grown.
Cat turned to her, and said something that Grrl could not understand.
"What?"
"Breasts.... hurt. Milk..... Drink.....," replied Cat.
Grrl understood what she was saying. Cat laid down, her back on the floor, her tail between her legs and her cheeks. Grrl leaned over as if to give mouth to mouth, closed her eyes, and placed her mouth on Cats left nipple to suckle. The milk that flowed forth was warm, and very sweet, as if sugar had been added to regular milk.
Cat moaned in pleasure, her eyes closed and visions of herself in a state of euphoria bombarding her mind. She felt as if she were on her way to an orgasm. Suddenly, she heard something that sounded like wet cloth being torn.
Cat opened her eyes, and tilted her head to the left. There she saw Grrl, eyes closed, still suckling, and with a long ropey tail growing from her backside. Her tail had torn through her purple cotton pants and was fully grown, tassel and all.
Grrl's ears were stretching to points, becoming covered with a fine layer of fur, also just as soft as Cat's. Her hair grew long, down to her tail, and turned dark brown. Soon afterwards, a mane began to grow. Cat soon took her left hand and moved it up the inside of Grrl's white sweatshirt, eventually reaching her right breast and bra cup. With her other hand, she pulled Grrl closer to her, and soon began to massage Grrl's breasts.
Grrl paused her suckling briefly, and to remove her shirt and bra, and then resumed pulling the milk out of Cat's breasts. Cat lifted her own head, and began to suckle Grrl's right nipple, her hands now around Grrl's back.
Fur soon crawled up from Grrl's backside, growing up along her back, then covering her front with a soft fine fur, very different from that of a donkey. The dark brownish/grey fur began to grow on her legs, eventually covering them, and then everything below her waist.
Her feet began to grow, but she didn't care. They stretched inside of Grrl's socks and shoes, eventually pushing forward through the sneakers, stretching out the socks. Simultaneously, both Grrl's and Cat's feet converted to hooves. Their feet stretched, and their toe nails turned black. The nails began to grow in all directions, and spread like a liquid on a table. The black nails on each foot then merged, and then split in the center, forming cloven hooves where their feet used to be.
Cat's breasts stopped growing, now easily twice their original size, and the muscles in her legs began to grow. But Grrl's breasts had just begun to grow. The fur now covered Grrl's body, even the tops of her hands. Her ass now began to swell in size, very slowly at first but speeding up as time went on. The fur on Grrl's legs inside of her sweatpants was extremely comfortable, and her swelling ass and tigthening pants just seemed to make the experience so much more erotic. Eventually, Grrl's pants ripped down the center of the seat, as did her panties, and they spilled to the floor. Yet the comfortable feeling of fur inside of sweatpants remained with her forever.
After some time, Grrl's breasts had nearly doubled in size, and Cat's own ass had swollen. Eventually, their faces pushed out into muzzles, but they never completed the change into complete donkeys. After their erotic experience, then both had human hands (though covered in fur), and the fur was soft, unlike that of a donkeys. They had breasts, and basically the shape of a human female.
After about 90 minutes of fondling and suckling, both Cat and Grrl gave up, and never reached orgasm.
Both embarassed, they crept to opposing corners of the trailer and went to sleep.
While they were sleeping, they and the rest of the donkeys were moved, the trucker driving to some other part of the nation.
The trailer came to a jolting stop, some time in the early morning hours, probably 2 a.m. The bars were closing, and a couple of drunks could be heard outside of the trailer.
All hell broke loose when the doors opened.
