Feeling the 3 inches of newgrown body tissue between his shivering fingers, Eric is toppled over by a raging pain that flashes through his changing body.
Dropping to his knees and hands he's choughing and breathing very hard, trying to regain his conciousness against the unbelievable pain that seems to focus itself upon his rear end.
Eric starts to pant, his tounge hanging out of his half-opened mouth, a second later he's whimpering, whining, too.
The pain in his rear is becomming more and more unbearable but he's trying not to give in to it, as something drives him ever deeper into his transformation.
Then, as the pain reaches it's peek, it subsides into something that can only be desribed as a orgasmic flash that rushes thoughout Eric's body.
He cries out, shaking his head in uncontrolled motions, pushing his rear end up into the air, while his body is still being grounded on its knees and hands.
His cries change into a canine whining as the small bump on his rear expandes once more, gaining in size and lenght. It seems to telescope right out of his body, as if it was allways hidden inside of him and is free'd now.
He's growing a perfect Golden Retriever's tail. Bushy, blonde, long and swinging from side to side.
Eric's snarling in horror, as he's still on all fours and seemingly unable to stand up as he was used to be.
The orgasmic rush that's still rocking Eric's body vanishes, but not without a further change...
