Roy loved to see Arnold transform and break through his clothes. Roy remembered the way he felt to first see his well built body. It was great with pleasure.
"Alright now it's my turn," said Roy. He grabbed the potion with great strength and gulped it down like a beast. The deep grumble occcured again. Then, Roy burst out in layer over layer in bulky, veiny muscle. He was more than a body builder. He was lord of the universe.
"Aaaaaawwwwww, yeah!," moaned Roy in great pleasure.
"Please, stop," said Arnold. It didn't help stop the growing. Roy kept growing taller and wider as his muscles expanded. Even his dick grew into a 12 incher.
"Oh, I am so getting horny right now! Don't you want to see me grow out of this building. See me get fricken huge and fuck you like never before," yelled Roy in his new deep voice. He struck a pose and as he saw his reflection he got an erection, making his dick a massive 16 inches!
"Rrrraaaaaawwwwwrrrrr!
All I ever need is muscle," said Roy. He grabbed a new potion and drank it. He grew too big for his room. His clothes tore off, and by flexing his pecks all of the buttons on his shirt popped off. Cum sprayed everywhere.
"Giimmmme MORE!,"said the new Herculean figure of what used to be Roy.
"I'm just going to keep growing and no one can keep me from that"
