Kid to Beast- A TS4 Story 19 (Patreon)

The next day the Fry Parents received a phone call from the doctors. Arian's test results were back." After analysing your son's urine sample, we have found that his testosterone levels are almost 500x that off a normal teenage male. We have never seen anything like this it is incredible!" The doctor paused for a response" So its not steroids! Oh thank goodness!" It was not what they feared. "I cannot suggest anything to combat this though, your son will probably end up growing a lot more, he may reach close to 8' and his body will drastically change." His parents were kind of in the middle of this transformation, an 8' son though wow, even they were stunned. Little did they know Arian had blown past 8' just the day before. They put the phone down. "Who was that?" A voice boomed, His parents actually jumped back in shock at the power of his voice. Arian's parents jumped out of their skin, they turned around and faced their gigantic son.  He was even bigger than yesterday!  What was going on?" "Oh Arian! Gosh you made us jump" His Father responded, startled by his son looming over him, muscles glistening in the hallway light. Just.. just the doctor confirming that you latest appointment went all ok that's all!" His father grinned. His parents stood there gaping up at their son, his colossal body nearly filling their entire field of vision. Then his Mother asked him “Are you feeling alright Arian, I mean even this growth spurt must be a little weird for you?”

“I feel fine! I actually feel incredible. Absolutely incredible! I mean look I am so STRONG!!! How do I look?” Arian treated his nervous parents to  a double biceps flex and then a most muscular. He bounced his pecs as well. Arian wanted his parents to see exactly how massive and huge their son had become! He stood a good 3ft taller, at least 300Ibs heavier and his chest  surpassed his parents in girth. In fact his chest was now a good 5ft around, his arms almost 3ft around "I am now 8'6"!" Arian exclaimed proudly, ( not knowing he had inched up to 8'10) his parents faces turning to fear. He had already passed the doctors predictions! " Yeah and I think we need some new scales, the old ones are broken can you pick me some up? Oh and some new underwear!" He felt his huge cock throbbing but managed to divert his urge to get his cock out there and then. "Sure that's fine!" Anything to please their son. His parents left immediately to town to pick up some food, new clothes, and scales for there monstrous teenage son. They were both left a little scared, both of them unable to speak for most of the car trip.
