tanding under the cold water listening to Jeff call him, Simon had no idea what the surge of testosterone into his body had done. While it was not affecting his mind because of the cold water, and the water was keeping his dick from full erection, Simon's muscle did not retain their original dimensions.
Slowing his back began to widen. While he had originally had very narrow shoulders to where they were barely wider then his waist, now they would give the impression of the V shape most men craved. While his back grew, his pecs also became thicker and harder. Soon they appeared like the traditional square slabs of meat that jutted forth. His abdominals hardened and developed so all eight were visibly separate. Finally his legs became harder, though not quite with the diamond shapes, it was obvious a person would have serious trouble finding any fat. Finally growing taller, Simon's head slowing inched its way closer to the ceiling.
While the hair on his body did not continue to grow, it did highlight the extensive musculature that Simon now possessed. Simon could now easily pass as a jock and would never be able to hide his changes.
