Following the effects of the hormonally flood of testosterone, Derek's bones begin to grow and expand in a torrent of pain along with his mussels working on themselves growing to the proportions of the newly founded testosterone factory in his groin.
A week before, Derek went to the doctor for his yearly required UA test it had come back clean and normal. His height then was about 6'7.
Now his body receives a powerful jolt by the infusion making him black out in tremendous pain loosing control of his ever growing body. His body begins showing secondary effects of growth after hitting the first stage, his arms begin to lengthen and thicken into 9ft forearms 2ft thick breaking the drywall leading to the Storage Dept. in a springlike manner.
While this is happening his legs shoot up like a plant does towards sunshine becoming 11 ft long and 3 1/2ft thick launching him out of the rest room and in to the Dept..
As the muscles in his arms and legs slow their growth and come to their final dimensions, his flabby and sum what fat torso starts to widen and tone making it become stronger and more ripped eating away what once was a hairy and flabby chest and midsection, his torso along with the organs inside grow to fill the new space.
He wakes up and looks around then looks at what has happened to him he finds that his pants, shoes and shirt had grown with him he was when standing a 19ft giant with a huge 8ft cock to match feeling embarrassed being out of the restroom he pulled up his underwear then his pants ,which were more like shorts, even though he grew his package still big, it was like having his perfect cock 18 inches long and 2 1/2inches thick only he was way bigger Now that his body was bigger he felt OK to the idea of being a very strong man with huge cock. so he was tired and took a short nap.
The manager had stopped in his office and panicked about Derek and didn't know what to do because he was kind of new at the job and he didn't believe he had time to call any authorities while he was searching for some type of ram to open the door to the bathroom, he wasn't a multitasker. He found something a steel-toe boot he ran down the hall to the bathroom he broke the door down only to find a recoiled sock torn in two and in need of repair he looked at the hole in the wall and seed a huge foot of a surprised Derek and Derek says
"Its the sock..."
He listened to Derek explain how the sock worked for him. So he took the sock not knowing how he was going to fix it, lucky he knew how to sew being a very good handyman and took action and finnished the work and cleaned the tattered remains of the sock and sewed it back. Then he put it in his pocket, and went home after saying to the now giant Derek that he was on his own.
He got home and then proceeded to do the same thing but this time he had a pair of scissors and a couple of other people to help he had the scissors ready he slipped his 6" cock in and balls too the elastic again tightened and his cock then got a semi-erection. It grew to 7", 8" then 9" it took about 2 minutes all that time sliding down like a python but this time marsden was prepared his assistants were ready to cut the sock off. He couldn't standing it he cut the sock at the balls at first they were the size of a small eggs he got them out and then started cutting down the center then he worked on the shaft and the head he got them out and then started removing the sock. He did it the cock didn't get out of hand and his cock grew to an smaller but still astounding 20 inches hard. now his assistants do the same.
What happens next, does something great happen...
