As Peter left the bathroom and went to class Katrina saw the bulge as Peter went to his desk. Katrina thought to have his muscles grow. Peter felt that his body ached all over and his clothes felt tighter. He raised his and to go to the bathroom he went into a stall and took off his shirt. He had a tight sixpack then his pants got tight and he took off them too. He had huge legs then is cock gows again by the unseen force. It keeps growing and growing and growing. Finaly, after a while it stops. Peter took of his underwear and saw his cock "It must be two feet now and 1.5 inches of girth!" Peter wisper-shouted. Peter feels his new long cock puts back on his clothes and looked in the mirror his saw that the bulge is definitely bigger and he went back to class.
