Tony was shaken awake at 5:15 AM for a 6:00 appointment for his temporary mane and tail. As he didn't have to get dressed he was ushered out of bed and into the family car. Once in the car he was passed some special liquid pony food in juice boxes. Tony noticed the brand, "Tranquil Stud". Was his erection a bit larger? Tony grinned as he finished the last of the food.
Tony's ball weights bounced at every bump. At first he yelped, but as the Tranquil Stud took effect, it felt wonderful. Like his balls had started growing inside his scrotem, even as the weights jerked and pulled. If he wasn't so zoned out he would be jerking off fiercely.
When they arrived at the facility, which was effectively a small specialty hospital. Tony was met at the curb and placed on a gurney. Once wheeled inside he was injected and sedated. A happy blackness claimed Tony. He had vivid dreams of being a naked pony boy. He grinned even as the first procedure began.
....
It was 6 hours after the Andersons arrived at the facility. A man clad in scrubs entered the waiting room and asked for Max Anderson. After sorting out ownership and privacy issues, the family was escorted to a conference room.
"So, Doctor Kenworth, how did it go?", Max could barely contain himself he was so anxious. The rest of the family was worse.
The surgeon began, "I'm very pleased. The cosmetic team shaved the sides of his head and transplanted the follicles into the central mane area, and extended it to the upper back. It will take time for the mane to grow out, but we have put in hair extensions that will last till there is some good growth. As for the tail, a growth stimulator has been attached to the tail bone via nanite grafts. This will stimulate tail growth, and begin the enhancement program. In addition to being a cosmetic tail that responds to the actual tail bone, it also delivers part of the pony cocktail as we call it. The bone will grow into the tail, followed by skin and finally hair growth. He should have a reasonable tail in about 2 years. Then we remove the device and stimulate the final growth. In the mean time, there are synthetic nerves that will allow feeling in the tail. Make sure your pony knows this."
"Yes doctor", Max quickly responded.
"We will be sure he knows.", dad responded. He was not happy with Max's happy tone. "His stupid son" was all he could think.
Dr. Kenworth resumed, "As for the penis enlargement, growth stimulation began in the special food. His penis has been augmented by implants and growth hormones. His penis now sits at 11 3/4 inches. It should grow to about 16 inches before we do the next surgery, where it's shape will be modified. We have cosmetically changed it to a proper pony coloration via tattoos. I think you will be happy. In addition we administered the chestnut anti-sunburn treatment. His skin will naturally darken over time before it changes to horse hide over 3 years."
"When can we see him?", Max asked.
He's in recovery. I can take you in shortly.
