Ty looked around the gym and spotted a classmate from school, who had just walked in. In fact, the teenage student had just filled out his membership application! Ty grinned as he saw him walking through the door, holding his gym bag. Ty could tell that he felt intimidated.
"Hi, Morgan! What's up?" Ty greeted.
"Hey..." the shy boy with long, straight, black hair replied. Morgan wasn't really skinny, but he wasn't fat either. He had an average build for a boy his age, albeit slightly shorter. Ty had always liked Morgan because he was kind to Ty, so he decided to give Morgan a blessing in return. Ty could see through Morgan's spandex workout clothes that he had a fairly average cock and balls, but with Ty around, that could easily changed. Ty wished for Morgan's equipment to double in size.
"What are you do-" Morgan stopped in mid-sentence as he felt a tingle go through his groin, followed by an amazing pleasurable feeling. Ty could easily see the effects on the outside through the spandex: Morgan's cock began to lengthen and thicken, growing longer and longer. It had already passed 7 inches and was nearing a thick 8. Below, Morgan's balls began to grow from their previous ping pong ball size, swelling up into firm baseball sized nuts. Morgan groaned as his cock snaked down into his pant leg before finally stopping at 11 inches long.
"Wha- what happened to me? Why do my pants feel so tight?" Morgan gasped out as he returned to consciousness.
