Thinking that everyone left you decided to have a little private time with Alice, doing it in her bed, then you both heard something strange in the living room like something fall.
"Want me to check that?" You asked her.
"Don't worry, I'll go, you can start getting prepared for our second round~" she winked at you and left the room naked only wearing a jacket.
She went down the stairs slowly looking at her surroundings, Alice started to notice the sex toys on the ground, seeing even more every time she checked until she began to understand what was going on. She saw the sex doll, it had the same appearance as Ema but as a plastic sex toy, the 4 dildos at her sides looking like they were her limbs, then noticed the necklace was inside one of the dildos, like a ring inside a finger.
"What happened to you" Alice smiled, grabbing the necklace, "and what were you doing with this?" She put it back to her neck, then a sudden spark of memories went to her mind watching the scene of Ema stealing the necklace and transforming into the group of sex toys she was now.
"Ohhh, now I got it..." Alice grabbed the main body of Ema that was just a plastic torso with a head, tits and a pussy in the bottom. "We are going to have some fun to make you pay for what you did" Alice giggled touching some of her gems transforming into a different creature.
Ema watched in horror how Alice's new body raised in front on her with an evil smile. Her legs were now a giang snake lower body with two tentacle-like cocks coming from it, she had two pairs of human breasts but one her arms was replaced with a crab claw while the other was a muscular arm that seemed to be from a minotaur, her head was entirely replaced by the one of a white sabertooth tiger, "we're going to have so much fun" Alice said in a deeper voice.
Using her strong crab libs she grabbed Ema's torso and inserted her two whole snake cocks, she loudly roared in pleasure while stroked her breasts with her minotaur hand. Then she grabbed the other parts of Ema, shoving all the dildos inside a pussy that was below her two dicks, Ema could feel the pleasure of all her parts but at the same time felt humiliated.
After some minutes of pleasuring herself with her now inanimate friend Alice returned to normal, "wow, that was just amazing wasn't it Ema?" She laughed looking at her plastic form, Ema was angry but could do nothing about it, looking how the necklace had printed the name "Alice" in above the gems.
"Let's se if I can get you back" Alice grabbed and put all Ema's parts together and touched her at the same time her emerald, thinking to transform her into a human. The dildos started to attach to her main body as the plastic texture vanished turning into a more skin-like one. Ema slowly stood up regaining her consciousness as Alice passed her clothes to her, getting dressed in that moment.
"I hope you had fun" Alice giggled.
"Yeah... It really was..." Ema said in a barely sarcastic tone leaving her friends house, "that necklace will be mine one day and I'll get my revenge" she thought as she walked to her home.
You went to the living room worried about your girlfriend, "what happened? you were taking too long"
"Don't worry, I accidentally left the necklace here and decided to have some fun with myself~ want to try it with me again?"
"Of course!" You both went to her room again.
