Jen was so lost in the ten minutes after she had transformed her mom that she hadn’t even noticed her room changed. Her makeup table was missing. “Oh yeah, I guess I don’t need that anymore.” She thought, as she looked for more changes. She now had a bathroom and a walk in closet to herself, which surprised her. Her family was wealthy, but her old room had been smaller. “Oh, maybe because I’m... horsey, I needed my own bathroom.” She thought. It didn’t explain the walk in closet, but she wasn’t complaining.
She stripped out of her tight tube top, took off her heels, pulled down her yoga pants, and decided to look at herself in the mirror while she was still wearing her sexy lingerie.
Jen walked up to the full body mirror in her huge walk in closet. This had sat in the corner of her old room, but when reality had adjusted, it had been moved to her closet.
She looked at herself. Jennifer Smith, the hot but nasty head cheerleader, was there in name only. Her light brown hair had always been beautifully maintained, but the transformation had made her hair even more beautiful. The same with her face, which again, was still similar to her old one, but now she looked like a model. Little things: her nose a bit smaller, her lips a bit plumper. The only big change above her shoulders were the two long, horsey ears that were on top of her head.
The biggest change was her body; the thin waist and toned stomach she had worked so hard for were still there, but looked even better. Above that, there were two very big changes she couldn’t ignore: her once B cup breasts, the only thing she’d ever been self conscious about, had exploded into L cups, even bigger than her busty mom. They were like spheres, two volleyballs on her chest, her hard nipples ready to give milk at any time. Jen took her bra off, exposing them. They didn’t sag at all; they stuck up straight, just like implants.
She noticed the bulge in her panties, and stripped herself of her custom thong next. Her new cock was in it’s sheath, just above her pretty pussy. She spun around, her massive ass jiggling a bit as she did so. She noticed her big, soft horse tail, her hand brushing against it. “Mmm, so soft!” She thought. She looked back down; she couldn’t be a cheerleader now, with these giant hips, but she realized she didn’t want to be. Putting that thought aside, she looked at her new, horsey anus. “Sex with this is even better than getting fucked with my old pussy was!” She thought, imagine how good it would be to sit on a pretty girl’s face. She paused. She really didn’t like guys anymore... at all. In fact, they disgusted her... but girls?
“Mmm... Candice’s pretty little face...” she thought, rubbing her anus and getting aroused. She felt her cock stiffen a bit, her pussy moisten... and a heat in her ass. She hadn’t been expecting that, but at this point, she didn’t want to question it; all she wanted a hard horse cock in her ass.
She really, REALLY wanted Candice’s face in her ass. Candice, her best friend, that she used to cheer with... and bully people. Her erection quickly faded as she thought about it. Guilt filled her. “Ugh, I guess Kyle got what he wanted. I was such a nasty bitch... but now I can make everyone happy!” She thought. She felt her cock harden up again. In her warped mind, the best way to make up for all those past years of bullying was to spread this curse, or virus, or blessing, or whatever it was.
She looked at herself in the mirror jerking off. “I’m a dirty slut.” She said to herself, smiling. On second look, though, she was also dirty in the literal sense. Her beautiful hair was looking a bit greasy. “I guess I could take a shower.” She thought, getting up and going to her own personal bathroom.
Walking by her door, she heard grunting and moaning from down the hall. “Mom’s room...” she thought. Her mom was jerking off for the first time... Jen drooled a bit, thinking about how much fun it would be to walk in on her.
“No! You already did... *that.* Just get in the shower and jerk off.” She told herself.

Jen had lathered up her sexy new body, exploring every part of it. She was shocked at how spacious the shower was; it was at least the size of her walk in closet. Come to think of it, her whole house had changed. She really didn’t want to think about that right now, though. She had something much, much more important to get to. After lathering up her hair, she got to work lathering up her cock, watching it expand to the full twenty inches it was meant to be.
“Mmmm” she moaned, thinking about spreading this feeling. The equine gift, she decided to call it.

Meanwhile, Jen’s younger sister, Emma, walked in their house. Despite being the “younger” sister, she was only about 10 months younger then Jen, and she had just celebrated her 18th birthday three weeks prior. Jen had taken advantage of the fact that she was younger quite a few times before, but now that they were both basically adults, that had passed.
“Mom?” Emma shouted. She was so worried about Jennifer, she almost hadn’t gone to school, but her mom had made her. She heard the sound of her mom’s moans from upstairs. “Oh.” She said, blushing. “Mom must have thought I was coming home later.” She said to herself. However, besides her mom’s moaning, she could hear another sound... the shower. “Did dad come home early? No, his shower’s down here... Jennifer!” She said, happily. Her sister was okay! She was going to wait outside of her bedroom and surprise her with a big hug.
As Emma went upstairs, though, a smell warped her mind. Both her mom’s and her sister’s scents were filling her mind and corrupting it. “Maybe... maybe I should just go in the shower with her. She is my sister after all!” She thought, entering her sister’s room, the thick musk intoxicating her brain further. She stripped down, hearing Jen in the shower.
*****
Try as she might, Jen couldn’t stop thinking about how hot it was when her mom transformed. Her mind kept drifting to it, and when she eventually came, her mom’s naked, horsey body was the image that did it in. Her huge cock splattered cum on the tile in the bathroom. “Ugh... I’m such a perv.” She thought, as her cock receded into its sheath. She’d wash the cum off in a minute; right now she needed to finish washing her hair.
“Sis! I’m coming in!” She heard from outside the shower, her younger sister’s voice dripping with lust.
“Oh no! I have to lock the door before...” Jen thought, as she opened the glass door in the shower. The sound of the bathroom door opening put these thoughts out of her mind.
“Sis! I missed you so much...” Emma said, walking in the open shower door. “You must have been so lonely! The least I could do is help you wash up.”
“S-sure Emma...” Jen said. Emma walked in, her nude body surprising Jen. Emma surprised Jen by giving her a naked hug, Jen’s huge tits covering her sister’s face. Jen felt her cock stiffening once more...
“Mmm Jen, something smells... goooood.” She said, breaking the hug. Jen sighed in relief before recoiling in horror.
Emma sniffed and found the source of the delicious smell. Jen frantically tried to stop her, but Emma started licking Jen’s semen from the shower wall.
Immediately, Emma’s expression changed. Jen could already see her sister’s vagina expanding and becoming a horse’s, and her ears had already relocated to the top of her head and become long and equine.
“Sis... that was delicious. But now I’m thirsty.” She said, a sultry look in her eyes. She immediately latched on to one of Jen’s massive mammaries, sucking as much milk as she could. “Ohhhh yes!” Jen moaned out, her cock reaching its full girth once again.
“No! No! Nononono!” She thought, as her sister kept sucking her corrupting milk. “Ugh... mom, and now Emma? It was fun when it was Caroline... and Amy... and it’s gonna be fun with Candice, but this is so gross!” She thought.
“No... look how good she feels!” A voice called from inside of her said.
Jen looked; Emma’s face had become more attractive, with her puffy, sexy lips a crimson color. Those sexy lips were sucking as much milk out of Jen’s tits as possible, alternating between them. She had grown her own 16 inch horse cock, throbbing and hot, a pair of egg sized balls filled with corruptive jizz. It was smaller then Jen’s, but still incredibly impressive.
Jen watched excitedly as her sister’s tits grew and became more rounded before she felt disgusted with herself again. Before, her sister had even smaller tits, an a cup, but they were growing bigger by the second, in fact they were growing even bigger than Jen’s! They finally finished at M cups, a whole size bigger than Jen.
Emma finally relented, collapsing on to the shower floor. Her hips had expanded, she gained a huge bubble butt, and her anus and pussy became horsey. Finally, she came, her cock spurting huge amounts of cum like a geyser, covering herself and Jen with cum. She sat down in the shower, her back on the tile, a satisfied smile on her face.
“I guess we really need to clean up, don’t we Jen?” She said, another sultry look in her eyes.
“Oh no! I turned my sister into a slut... just like mom...” Jen felt dread as she thought this to herself, desperately trying to fix the situation, focusing on making her sister normal...
“Huh... wait... Jen! I have tits! And a cock!” She said, happily.
“Wait... you remember your old body?” Jen asked.
“Yeah, why wouldn’t I? Wait... you weren’t like this two days ago, were you? And when did you get a bathroom?” Emma asked.
Jen hugged her horse herm sister. Something good came out of this; this was the first time anyone kept their old memories! For some reason, she felt fine with changing Emma into a horse slut as long as Emma kept her old mind. She would’ve been grossed out if it was her mom, but this was... Emma.
“Oh... Emma, I have a lot to explain to you.” Jen said.
“Yeah you do! But let’s clean each other up, Sis. This body feels really good, but I don’t like being covered in jizz. At least... not my own.” Emma said, smiling.
*****
After Jen and Emma had cleaned up, they had found clothes that fit their new bodies (Underwear for the two of them; a mini skirt and a v neck for Emma, and a pair of daisy dukes and a tank top for Jennifer.) and sat in another new addition to Jen’s room: two chairs across from each other; in between was a fancy tea table and two other chairs. Jen had made tea on a portable stovetop, and grabbed a bottle of her own special “milk” and “cream” from a mini fridge. She saw tube connections in the fridge and figured out that they were connected to her milkers.
“Alright Jen. So... you were cursed, and then you did this instead of turning yourself back to normal. That’s so...” Emma started. Jen was about to defend herself; “the curse messed with my brain! I was in horse heat!!” but then Emma finished her sentence.
“...hot!” Emma exclaimed. Jen could see a bulge forming the miniskirt she was wearing.
“What?” Jen asked.
“You heard me! That’s so sexy, big sis!” Emma proclaimed before pausing.
“Wait. So no one remembers their old selves?” Emma asked. “Come to think of it, I thought everything was normal until a little while after I changed.” She finished.
“Oh! I think I might have been able to bring your old memories back. I focused really hard because I felt bad about mom’s change.” Jen said.
“That’s so cool! Mmm, I can’t wait to change people!” Emma said
She paused.
“You changed mom, too?” She asked.
“Yeah, why?” Jen asked back.
“Because for a while, I remembered mom as the horny slut she is now. It didn’t even phase me that she was jerking off upstairs... So it’s not just the person that changes. Reality does...” Emma said.
“Yeah. That was part of my first transformation.” Jen said.
“So I almost ended up like mom? She’s still jerking off right now.” Emma finally said.
“Oh... Um... I guess.” Jen said.
Emma's bulge grew bigger as she got up and hugged Jen.
“Thanks for changing me back, Sis. That sounds scary... and a little hot.” Emma whispered that last part so Jen couldn’t hear.
“Okay. Now let’s make some more sluts!” Jen said.
“Yeah, let’s find some hot girls!” Emma said, before a look of realization hit her face. “Wow, boys seem totally disgusting to me now.” She said.
“Yeah, that’s part of it.” Jen said.
“Good. Let’s make them yummy horse sluts too!” Emma said.
“Wait Sis. I think we should wait for dad to get home. I bet mom’s gonna have a really tasty meal for us.” Jen said, smirking.
“Ooh. Okay. Why don’t we check out my room?” Emma said. Her room had changed just like Jen’s, and she was excited to see it.
“Okay!” Jen said, and the two headed out.
