"Want to try going fully feral?"
Rachel looks down at herself and sees a large puddle of cum on the ground, not sure if it was hers or Zoe’s. She raises a hand-paw to her stomach where she stills feels the warmth, his seed, within her. Looking back to Zoe, she nods as she says, "Let's do it!"
With a wink and a smile, Zoe lets his penis retraced into its sheath as he gets up. Rachel can only admire his powerful form as he walks over with renewed confidence as he grabs both masks and returns.
"Quite the trick with your penis," Rachel comments.
Smiling, he explains, "It's odd, it's like I've always had a penis for my entire life. I know that's not true of course. Much better than a human penis though, I'd have to wait for it to shrink on its own!"
They both laugh as Zoe kneels down and raises Rachel's mask as he asks, "Ready?"
Nodding, Rachel watches as Zoe puts the mask on her.
"How does it feel?"
"Strange. The tingling's back- oohmmf"
Startled at the strange sound, Zoe asks with concern, "Are you ok?"
A tense moment passes before a more-gruff, though still very female, voice comes back from the mask’s mouth, "Yeah, I couldn't move my mouth there." Raising her paw-hands to the mask and opening her eyes to watch, she touches her new canine muzzle.
"You're so cute!" Zoe laughs as he watches Rachel.
Looking up to Zoe, Rachel gasps. "Are you bigger!?" All she can do is watch as Zoe seems to grow bigger and bigger.
"No," Zoe responds with a smile, "You're getting smaller; you're becoming a true vixen!"
Looking down at her shrinking body, pops and soft grinding alerts Rachel to her arms and legs and watches as they slim down and shrink as her shoulders pull inward and her chest starts to grow outward. Through it, all she can say is "I am!” As small pinches come from her stomach. Rolling to her side she leans over and watches as multiple rows of canine teats grow under the fur.
With glee, Rachel proclaims, “I'm going to be a fox! I’m a vixen!"
Zoe places his mask on his face as he goes through his own transformation.
As the transformations end, Rachel looks over to Zoe and takes a deep breath, filling her nose with Zoe's sweet aroma.
"Well?" Zoe asks with a smile.
" You smell wonderful in this form. And you look so hansom!"
"Thank you," Zoe says quietly as he looks down at Rachel's swollen vulva. "Ready to be filled with my seed again?"
"Yes please!" Rachel says, shivering at the thought as she raises her tail and presents herself to him. It was finally here, her dream to be mated as an animal was finally going to happen! She can hear Zoe approach then a weight lands on her as she steadies herself under Zoe's heft.
"I've never seen foxes mate but I know what I'm doing. I feel so powerful Rachel, so aroused." He shifts a little as his penis slides between Rachel's swollen opening. "Are you ready for this?"
"Yes!" Rachel moans as she feels Zoe bit the scruff of her neck. A calming pleasure fills her as the knowledge that a strong fox was ready to mate her. Taking a deep breath, filling her lungs with Zoe's scent, she waits.
For a moment or two, Zoe glides himself around Rachel's opening. Then, with a grunt, he pushes into her.
"Yip!" Rachel cries out as she feels Zoe's entire length bury deep within her, ramming her forward, only Zoe's strength and bite holding her in place as he drives into her again.
"Oh Merlin! I can't believe how big you are!" Rachel cries out as Zoe starts to pick up speed.
Grunts are the only response as the bite keeps Rachel in place.
Rachel gasps loudly as she feels Zoe's large knot press against her with a final push as warm seed fills her. Another thrust from Zoe sends even more warm liquid floods into her.
"I'm filling up!" Rachel screams as she reaches her own climax sending cum past Zoe's knot as contentment fills her mind like never before!
Zoe's entire weight seems to fall atop of Rachel as a final stream of cum flows into her. It was too much though as they both fall to the ground. Rachel closes her eyes trying to bask in the incredible afterglow. All thoughts, cares, and worries seem to leave her mind as she drifts into a light slumber.
