... the front of your pants splits open and the kid's straining boxers explode, catapulting your engorged cocks out into the open. Horrified, you see your own hard-on hauling the remains of your briefs out with it. For a second, the tattered white material hangs from your knob, like a ragged flag of surrender, before slipping to the ground.
Staring down, you watch incredulously as your rampant bobbing tools continue to expand until the two shafts are virtually jousting with one another.
"HAW HEE HAW!" the kid brays, eyes half-closed, his face a picture of ecstasy. Even as you watch, his chest starts to expand, his belly growing rounded, a stiff mane of hair bristling from his neck. And the hand that was on your balls is wrapped tight around his huge throbbing cock, jacking it hard with fast, eager strokes.
"HAWWW! HEE HAW, HEE HAW!" he brays again. Releasing you from his grasp, he bends over his pumping fist, his tail rising, stretching rigid. "This is awesome!
YEEHAW! YEE HAWWW! HEE HAWWWW!" His speech is well-nigh incoherent now, each successive bray more protracted, more bestial.
Everything in you wants to run - to get away - to be anywhere other than next to this transforming kid with his huge cock and sexy, outstretched tail.
Sexy? No!!
But it IS!! The way it protrudes from his shorts, like the dick jutting out in front of him, has got you hypnotised - drawn to watch him, to emulate him, to do all the darn things HE's so happily doing...
Desperately you try fight the urge to grab hold of your own dick - but it's impossible. Your body has a mind of its own, and before you know it you've seized your huge hard cock in a warm, tight grip and are pumping away with frantic strokes.
And just like his, your tail is a taut hairy arc jutting out from your butt. So long, so thick, and....
"HEE HAWWW!!!"
Gasping and shuddering, you fall on all fours, one hand clutching your cock as your hot load sprays out in front of you. The sound of ripping fabric again fills the air as your pants split from cuff to knee, your shoes burst apart and your socks tear over your elongating ankles. You can tell, without even looking, that both feet are swelling and changing into hooves - you can feel the hardness of them pressing against the floor - and even more disturbing, your arms are beginning to stretch to match the length of your legs.
In the midst of all this, a loud grunt and a lengthy spattering sound tells you that your companion, too, has shot his bolt. But you don't look at him. Instead your eyes are glued to the spasms afflicting your hands as they twist and clench and deform into horny lumps - hard, dark and shiny. Hooves... Your young man's hands are now hooves!
"HAWWW!" you bray again, clomping them on the floor as your arms grow even longer, pushing you upwards, and your shoulders broaden, splitting your shirt asunder. Dismayed, you hear it rip even more as your back widens and lengthens and your chest barrels outwards.
"HAW, HEE HAW, HEE HAWWW!"
Your legs - your HIND legs - are now fully extended, supporting your growing weight, the only item of clothing left on your body being your partly ripped, massively straining pants. Twisting your neck, you look round for the guy that is with you and see...
