"Mr. Anderson, on behalf of myself and the hospital I am deeply sorry for this mix-up. Of course there will be no charge for the erroneous breeder treatment."
"There better not be", snapped Max. "We did not request any breeder enhancements, and we certainly did not approve any mental conditioning!"
"You're damn right we didn't", dad was madder than Max. "If you have damaged my son rest assured you will be hearing from our lawyer."
"it's alright dad, I'm fine", said Tony. He had been a spectator to this point as the doctor had brought the family in. "After a while I started enjoying it. It was fun."
Tony's now 13 inch black and pink mottled erection stood proudly at attention despite the recent milking. His new bangs hung down in his eyes causing him to toss his head. He felt his chestnut mane tickle his mid-back. His matching tail swished lazily back and forth, almost brushing the ground as it tickled his ass. His skin had already darkened a few shades from the treatment and his recent outdoor nudity. The amount of weight on his balls was more than double what it had been, which Tony barely noticed. His balls were approaching the size of hen's eggs.
He stood tall on the balls of his feet thanks to his shoes, but even so he had grown from his original 5' 10" to 6' 1". What body fat he possessed before was gone and his muscles bulged with new growth and power. He looked like he had been lifting weights for the last year. Tony liked what he saw in the wall mirror. He flexed and posed even as the doctor and his family talked. Thanks to the treatments his muscle soreness was fading quickly.
"Doctor, is that my son talking or your conditioning?"
"Mr Anderson, normal breeder conditioning takes 10 4 hour sessions over two weeks. Your son barely started the treatment. We do use a special food cocktail with the first session to promote rapid growth, which accounts for his slightly increased size. His penis will likely grow some extra inches, as it has already. He was bound to grow a bit even from the racing treatment. He'll just be a bit larger than your normal racer. He might even have a speed advantage. As far as liking the treatment, I seriously suspect your son was bisexual before we started."
Everyone turned to Tony who nodded affirmatively in a disturbingly equine manner. He all but pawed the ground and snorted.
"Well I have to admit he looks great and he seems to be himself." Max looked a little more at ease seeing his brother's attitude, not to mention his incredible appearance.
"I feel good. A little sore in places, but that is fading. I like my new look." Tony looked at Max and his dad, "Can we get out of here? I really don't want to miss the movies tonight."
"What about it doc? Can he go out tonight?", dad asked with his arms folded.
"He should be fine. By now all the sedation and aphrodisiacs have worn off, he is clear to go home. If there are any issues call me at once.
With that, the family headed for the car and the drive back home.
