"I want this one here." Meg said pointing to the Earth gem "she looks like an amber rock, and I like it."
"OK, and here is the amulet for your gem." Veronica said handing over the amulet.
Meg put the amulet around her neck quickly saying "I'll put it now, as it takes an hour for the transformation to begin, we'll be home by the time."
"I'm sorry, but I forgot to warn you that inside this store has a lot more magical power than elsewhere, so I think it's good that you take off your clothes now." Veronica said
Before Meg could say anything, she felt her clothes start to tighten. she took that as a sign that the transformation had already begun and that if she left she would be naked before she got home. "Isn't there a more reserved place? I don't think it's a good idea to undress here in the middle of the store."
"Isn't there a more reserved place? I don't think it's a good idea to undress here in the middle of the store." Veronica said
"Can I go along with her?" Ashley asked
"It just depends on her approval." Cristine said
"May come. I prefer my sister to see my transformation. It wouldn't be fair for me to hide after I saw hers." Meg said
On the way to the back room, Meg led the way, and halfway Ashley watched as her tail grew.
Inside the room, Meg began to undress as quickly as possible saying "No more, my clothes are too tight." She undressed as she happily wagged her new tail, which had stopped growing and, by her estimates, was at least three feet long.
When Veronica started picking Meg's clothes off the floor and tucking them into a corner, they realized that she had stayed in the room, just like Cristine.
Realizing their surprise, Veronica said "You don't have to be ashamed of us, we are your personal salespeople, it is only natural that we stay with you."
After that they all focused on Meg's transformation, which was already perceived to be taller than before, at least one more foot at least. Her body began to be covered with fur, the color pattern of a cow. Then her feet became hooves, and her breasts grew to huge K-cup. Her nipples multiplied, leaving her with four in each breast. Her head changed, gaining some cattle traits without losing her human characteristics, ending her horns growing. The next step of the transformation was her bull's cock, growing and reaching 18 inches of hard meat, according to Veronica who measured it as soon as it stopped growing.
"Yeah, this feeling is indescribable." Meg said
Ashley was also very excited about the scene, her cock was so hard it didn't even look like she had fucked a mare just minutes ago.
But Meg's transformation wasn't over yet, as a pink dot formed on her belly and grew into an udder.
Seeing Meg in her final form, playing with her new dick, Ashley turned her back on her, lifted her tail and said "Meg, come here and fuck my mare's pussy until you're satisfied."
"That's exactly what I intended to do, and I'm warning you that I won't hold back." Meg said and then began to fuck Ashley.
While being fucked by her transformed sister, Ashley noticed the tent formed by Cristine's erection, which made her think "Wow, her dick is huge for a human." so she turned to cristine and said "I don't know how you stand it, your hard dick like that inside your pants must be hurting you, take off your clothes and join us."
"And you Veronica too, don't be left out alone." Meg said
The two saleswomen undressed, Cristine's cock was really huge, looking 15 or 16 inches long and 3 inches thick.
"Cristine, you will fuck me now, right now." Meg said. With a sign of Ashley approval, Cristine stepped behind Meg and penetrated her cow pussy. "This is amazing, fucking and being fucked at the same time is a surreal experience." Meg commented
Joining the group, Veronica stepped under Ashkey's horse body and placed her pussy against Ashley's cock.
"No Veronica, it's 21 inches, I can kill you." Ashley said
"Don't worry, remember that I am not really human, but a creature generated by the magic of the store." Veronica said.
Ashley was surprised that her dick actually got inside Veronica, she could see through a mirror on one side of the room that the shape of her cock was perfectly visible through the bulge it formed in Veronica's belly.
The orgy continued until Meg, feeling an unfamiliar pressure on her said " I think I'll come."
"I'll come too." Ashley said
"Me three." Cristine said
The three of them came at the same time, and Ashley realized that Veronica was having an orgasm too.
After the orgasms ended, they sat on the floor to catch their breath.
The twins were still amazed that Cristine's cock, even limp, was huge, and Veronica had so much fucking in her womb that she looked ready to give birth to triplets.
