The fox starts to pant eagerly as you reach out for the tail, the tips of your fingers grazing along the surface of the rubber for a split second before the four-tailed fox darts behind you with an excited vulpine giggle.
In one deft motion, the fox lifts the back your shirt, gripping the base of the tail in its other paw and firmly pressed it into the small of your back. The patch of skin where the tail has touched is alight with an intense warmth, the latex softening and melding into place with a putty-like consistency before the kitsune lets go and backs away.
Before you can process what's happening, those keen, intense eyes of the creature lock onto you once more. Watching intently as the rubber continues to meld, soften and spread along your lower back. Engulfing more and more of your body as that warmth continues to spread.
The tail now has a presence within your senses that bombard your psyche with intense feedback. The motions and reverberations as it sways, curls and wags. The ripples of the rubber envelope coursing along its length as the air subtly shifts around within.
The warmth continues to spread, a tendril of goo running along your spine all the way to the base of the skull before plunging into your hair. Within seconds, two bits of rubber emerge into vague triangular shapes before fully forming into a matching pair of rubber vulpine ears.
That's when a voice echoes out around you, with an ethereal, otherworldly vibe.
"Yesssss, coming along nicelyyyy~ You'll be a lovely rubber fox just like me before long~
The kitsune approaches once more, running one of its paws along the contours of your head as that paw traces further upwards to your newly formed ears that twitch in response to their very tips being grazed.
"So sensitive, aren't they? Don't they feel wonderful?"
Vulpine purrs rumble around you before she leans in further, placing her muzzle right next to your right ear with a soft, sultry whisper.
"Do you wish for more?"
