Teri decided not to meet the French girls just yet, so she started following them while staying hidden. She followed them around for about 5 minutes before starting to prank her, and the first thing she did was wish Louise to turn into a centauress.
The girls were walking through the forest when Louise stopped in front of Alice. Suddenly she felt her pants getting too tight as her ass stretched and stretched the fabric to its limit.
"What's the problem Louise? You are not feeling well? Is there something that.....?" Alice asked worried about her friend, when the fabric of her pants gave way and began to tear.
"I'm feeling weird. Something is happening to me but I have no idea what." Louise said and then several cracks started to be heard one after the other and she held on to a nearby tree.
"No, stop it. Are There someone nearby? Anyone please help my friend. There's something hurting her and I don't know what it is." Alice screamed desperately believing that her friend was in severe pain, but there was no one besides Teri around who could hear her. She looked around a bit hoping someone would show up, but when no one did she turned to Louise again, seeing that now her friend, who was getting taller, as her backside seemed to have lengthened, and her legs had assumed a strange form but which were familiar to her.
"This is weird. I feel my bones breaking and my insides being turned over but still I don't feel any pain, I'm just having trouble keeping my bal..." Louise said when her shoes broke and slipped out of her feet, which had become hooves, and she almost fell, but she managed to keep her feet. She looked back and noticed that she had a tail now and a fully equine ass. Short caramel colored fur already covered her legs and ass and fanned forward while a second pair of legs that also ended in hooves grew above it. With her new legs fully formed she stopped holding on to the tree and let herself stand on her four legs, meanwhile she felt something happening in her ears and took her hands there and found that they had become pointy.
"This forest is very strange Louise. First we came here all of a sudden now your lower half became a mare's body." Alice said
"The weirdest thing was that I didn't feel any pain even though my bones were breaking and other injuries that happened while I was transforming. Don't we just fall asleep and are we dreaming?" Louise said, getting rid of the rags that were once her pants, which were still attached to one of her back legs.
"Ouch... It's definitely not a dream. You've really become a real centauress." Alice said after having pinched herself
Teri was having fun masturbating while watching in secret and then wished that Alice too could become a centauress, but with a different transformation order.
"If the place is responsible for its transformation then will something happen to me too?" Alice asked
"I don't know but it doesn't feel bad. It's only going to be a problem when I come home like this." Louise said admiring her new body, then she looked at Alice and noticing something unusual about her friend she asked "Is that hair escaping under your skirt?"
"What?" Alice said and bent down, lifting her skirt and seeing the long blonde hair that was down the back of her legs. After seeing what had happened to Louise she had an idea what it was and, touching it above her ass, she was sure she already had a horse's tail. "It's happening to me too, I'm changing." She said then noticing two bumps growing on the sides of her waist, soon growing with hooves forming at the ends, which would be her new front legs. Louise stood next to her and said that her friend could lean on her if it became difficult to stand during the transformation.
Teri wished Louise to acquire a new fetish and get horny watching her friend transform.
Alice leaned on the back of her friend's horse body as her feet also became hooves and her body began to lengthen, with several cracks being heard from her bones as they broke and reformed, as well as her new muscles formed.
Louise couldn't take her eyes off her friend transforming, her mare pussy getting wet, and then her realizing and wondering how she was attracted to her friend transforming into a centauress. She saw that the girl's transformation was almost complete, as the lower half of depa had already fully become a horse's body and only the fur was missing. Now managing to stand up without problems, Alice got off her back and without thinking, Louise grabbed her friend's head and kissed her, feeling her ears getting pointy in her hands.
"Louise, why did you do this?" Alice said pushing her friend away after her sudden kiss, this while her transformation was completed with short white fur covering her horse half.
"I don't know, I just started to get attracted to watching you change and I couldn't help myself. I'm not a lesbian and I've never had any interest in girls, at least not in this sense." Louise said
"I also only like you and any other female as best as a friend. Now control your impulses and we'll continue to look for clues to where we are or a way out of the woods. Then we can look for a way to get back to normal." Alice, now fully transformed into a centauress, said
The pair of French Centauress girls continued to walk through the forest looking for a way out with Teri still hiding behind them. The stalker then teased the pair by wishing their libidos were doubled.
The last wish had no apparent immediate effect on Alice, but it was different for Louise, who was walking behind her, who began to pay more attention to her friend than to the way, looking from the head to the half horse, from the back to the legs, then for the tail she waggled and her ass, but at the sight of her friend's mare's pussy the desire became too great again and she couldn't resist.
"I'm sorry Alice, I'm so horny and I can't hold back anymore." Louise said and lowered her human part, burying her face in her friend's ass and starting to lick her pussy
"Oh no, stop it Louise." Alice complained, but deep down she liked the intrusion and let her friend continue what she was doing while her horniness only increased.
Louise had completely given in to lust, but she was still very horny and felt her pussy abandoned, especially now that it was too far away for her hands to reach. "Alice, help me, I need someone back there." she said
"But I also don't want you to stop playing with my pussy." Alice said, thinking a bit she had an idea. She turned around and stood by her friend's side while facing the opposite direction so that her front was side by side with the other centauress's backside, then she bent over leaning over Louise's ass and hugging it, tucking one whole hand in her pussy right after locating it.
Louise groaned at the intrusion that was more than she'd expected, but at the same time she felt like it was what she needed at the moment. She then reciprocated by hugging her friend's equine ass and tucking her hand into her mare's pussy as well.
Alice and Louise were lost in lust and for a while nothing else mattered to them. They didn't care if they were lost in a mysterious forest, nor did they care about the transformation they had gone through, they only cared about feeling pleasure and giving pleasure to the other. At the same time Teri was still peeking and masturbating, having lost count of how many orgasms she had already had.
The two centauresses continued handfucking each other until they came, Alice was first and Louise shortly after. Then they repositioned themselves, standing side by side facing the same direction, and laid their horse halves on the ground to rest a little before walking again.
