The ooze coating your body swirls and blends, gradually taking on a deep red hue as the light of the room glints off of it. The girls only help it along, stirring it all together with their hands (or paws, or hooves, or whatever you might call them), and once your entire body's been covered in a single, even coating of that cherry red rubber, they go to work molding it.
The rabbit moves to your face, leaning in as though to kiss you, pressing her lips against yours... only to blow into your mouth, the rubber along your face expanding outwards, forming into a long muzzle as two rather large nostrils pop out atop its tip. With the muzzle done she moves to your ears, giving each a playful nip and then tugging them upwards with her teeth, the stuff stretching up and above your head, pulling your ears into tall and long points.
Not to be outdone, the cat's been focusing just above your ass, gradually pulling out the rubber. The stuff seems to just fill itself with more rubber as it's stretched, reaching out behind you a few inches before the mass she's pulled dips down, forming into a long, solid mass of red shaped to look like an equine tail. Not quite satisfied to do that alone, she reaches around to your hands, her own paws melting over your fingers, your palms... your entire hands quickly consumed by the black latex of her body. She soon pulls her paws back away, both of them fully intact, and you can only watch as the stuff on your hands solidifies into a pair of solid, shiny ebony hooves. She bends down to get to your feet and do the same there, and as she does you notice the pig for the first time.
Just standing in front of you, the pig girl seems to be doing nothing more than watching the other two, waiting for them to get a good ways in. Once they have, she swoops in, reaching both hands down the front of your pants. You watch as her arms start to "sweat" like the three of them had, all of the gunk sliding down your pants... and the bulge at their front gradually growing as you feel the fluid submerging your member deeper and deeper. Once your pants start to strain the girl seems to realize there's no more room for them, and opens up the front, allowing your junk to practically explode out of them like a jack in the box popping up. You can hardly contain your horror as you see your new member, having been shifted to its former self to a massive length of at least a two feet, its broad mushroom-like tip bearing no real resemblance to the one you're familiar with. She slides your pants down just enough to give you a look of your massive balls as well, the ball sack looking as though it's straining to contain them as it rests on your smooth, cherry-colored rubbery thighs.
Their work apparently done, the cat and pig girls step back. The rabbit, on the other hand, just stands in front of you, pensively. After a few seconds of thought, she swirls a single finger around your member, which you now realize has no hole at its tip. As though she's acting on that realization she dips a single claw into the tip, piercing into it before pulling back and leaving a single, thick drop of white rubber that reforms into a nozzle not unlike what you might expect to see on a pool ball. Having done that, she joins the other two to admire the new horse "toy" they've created.
