Jennifer smiled as she observed Brad's toes get stubby and furry. His skin seemed to crawl and bubble over his changing feet which were turning into clawed dog paws fast.
Jill, still removing Brad's clohes one by one, was also smiling lustily, as she saw dark fur creeping up the boys legs and lower abdomen.
"Heh, Braddie seems to like it the canine way," the Vixen purred.
"I... don't... understand," Brad muttered, as he felt the growing fur work it's way up his stomach. His penis felt eerie... but despite the gruesome transformation he was undergoing, it hardened in arousal.
He wanted to stand up and run, but the two foxgirl's hands held him down on the ground carefully but firmly.
"Yeah, the big canine way," Jennifer concluded her vixen sister's sentence, slowly trailing her clawed fingertips over Brad's transforming cock. While the fur sprouted all over the quarterback's body his penis had changed shape to resemble a german shepard's slick, pointed doggy cock. A furry sheath was forming while Jen was slowly stroking the enormous piece of meat.
The other girls got more and more exited by the boy's transformation and started petting, licking and kissing themselves with growing intensity.
Brad was shocked out of his mind as the transformation continued to reshape his hands to black-furred, clawed animal like talons.
A fuzzy tail grew out of his lower back as one of the foxgirls started licking his new alien dog cock. Ecstatic rushes flashed trough his body.
His face seemed to explode as his face extended itself to form a muzzle.
Then everything went black.
