In his haste to impress the girls Shane pushed too many buttons. Instead of inputting muscle mass increase of 10% he hit the zero twice setting the increase to 100%. His body began to shake more violently with each passing second. At first it was a slight mummer but quickly developed into a full fledge quake. His body grew noticeably bigger all over.
The girls had seen on-line morph movie before but this one was for real. Their friend Shane was growing right before their eyes. Jackie watched Shane expand bigger. As a matter-of-fact his whole body was getting bigger than her ex. The tank top he wore under his Hawaiian shirt exposed his upper chest to the world. The exposed areas expanded out further and further until the shirt could not hold back the growth any longer. The tank top, now vest, had ripped down the middle showing off his bare chest and abdominal muscles. The board shorts Shane wore to the beach were being stretched to their limit as well. His legs grew bigger than his shorts could hold. His growing thighs pushed the hem of the shorts higher up the legs until they resembled hot pants. His arms grew at the same amazing rate as his legs with the similar effect. His biceps and triceps split the sleeves of his shirt as they grew bigger. The most pronounced growth on Shane was in his tight shorts. All those huge muscles required a lot of testosterone to maintain their size. The testosterone factory was working overtime to supply the needed muscle food to feed his muscle mass. To keep up with demand it had grown larger as well. Over all Shane was enjoying his new size and the bulge in his shorts showed it.
“Well girl, do you believe me now?”
