"We should rush things.? Why not enjoying ourselves a little bit..." Anna used her right arm to touch their shared pussy rubbing a little bit their clit.
"Yes... Keep going" Christa moaned following Anna's crazy ideas, Ashley enjoyed it too but don't wanted to admit it, this time she hardly tried to stop Anna, but the pleasure got stronger, moaning a bit. Anna introduced her two whole fingers noticing that the three were enjoying it, pulling them it and out faster to make them cum. After some minutes of pleasuring themselves while Ashley grabbed their left boob the three headed women squirted again feeling a synchronized orgam.
"Oh... God, it was really good..." Ashley tiredly said.
"I told you it was going to be awesome!" Christa excitedly said.
"Hoof... oof... I knew you would like it..." Anna said sweating, "why don't we try more things?" She giggled.
"Ooooh... I-I think is enough for now" Ashley said sweating too.
"Party pooper" Christa said in a lower voice, triggering Ashley again.
"I'm not a...!" She tried to finish her sentence but Anna started to touch them again, "st-stop that! We had enough!" She used her arm to move Anna's, making her other two friends laugh, enjoying to annoy her.
The girls began to fight with themselves, Anna and Christa wanting to have fun while Ashely stopped them, meanwhile Anna's German shepherd Chase went down the stairs chasing the noise the three girls made, then he grabbed the blanked with his mouth, walking to the women.
"Oh Chase! Want to have some fun with us?" Anna said.
"No! We're not getting involved with your dog!" Ashley said trying to grab the blanked from Chase's mouth but he pulled harder. "Give me that!" Ashley pulled even harder making the blanket fly, falling on top of them and Chase, starting another fusion.
At that point the women couldn't fight but feel how the magical artifact started to merge their bodies, Chase slowly starting to melt with them and disappear in their body, growing a lot of fur on them, their body morphing and being changed by Chase's influence. Ashley quickly removed the blanket with her left arm after the fusion finished.
The women didn't feel dizzy anymore but worried about what happened, Ashley inspected her own arm seeing that it was completely covered on fur with long claws replacing her nails. "What is this" she looked down, appreciating that all their body was covered on fur, the same colour of chase.
"Yeah, I feel weird..." Christa said, then looked at her right, opening her mouth of surprise after she looked.
"What?" Anna said confusedly looking at Christa noticing the change. "No way... We merged with Chase!" She looked that both Ashley and Christa had dog faces, but more wolf-esque, "I suppose I look like that too"
"Yup" Christa nooded.
The women walked in front of the mirror, fully appreciating their new shared body. A full three headed anthropomorphic German shepherd, a little big muscular, and with their breasts slightly bigger that before, also covered in fur. They looked down noticing that small three pairs of nipples were in their chest below thier boobs, for their surprise now they had a wolf dick, in top of their now wolf vagina, not forgetting how they waved their wolf tail in their ass.
"This is amazing!! We can do lots of fun stuff with this! We could scare people or doing wild animal's stuff" Christa said excitedly.
"I feel... Great too!" Ashley said, "I'm way more stronger! I feel should do more things too!" She raised her furry arm.
"Yeah, but first, we should use our new assets" Anna said as she masturbated their shared penis, while Ashley inserted some fingers inside their pussy below their cock, feeling a really strong pleasure. Eventually the three headed dog came from both of their two sex organs, leaving a mess on the floor.
"Ugh! I can feel like I can do this forever, I'm full of energy!" Anna said.
"We should calm down, but a little more oof fun won't hurt anyone" Ashley smiled.
"Now you're understanding! We're going to have so much fun!" Christa howled like a wolf, Anna and Ashley imitated her, enjoying their new form as a shemale cerberus, creating a new legend like the werewolf.
