WAIT, Ty thought, that's not enough is it? After all, giving Matt 6 inches would only get him up to 6'2". Ty wanted Matt a bit bigger, so he revised his wish to 8 inches of height, bringing Matt to 6'4". To put a bigger twist on to the wish, he wished that it would happen from the bottom up.
Matt felt a tingle in his feet, but he continued watching the teacher. Inside his shoes, his feet began to grow, from their previous Size 10's to a manly Size 14! Ty wished that while his clothing wouldn't adjust to his size, no one else would notice or care about it ripping.
With a loud RRRRIIPPPP, the shoes fell off. Matt's new huge feet looked out of place on his otherwise unchanged frame. But that was changing.
Matt's legs started to stretch out, longer and longer and thicker and thicker, getting hairier as well since Ty had wished earlier for him to become more manly. When they stopped, Matt looked freakish, with the upper body he always had, but with the lower body of a jock.
His cock grew to a thick 10 inches soft. It flopped lazily on his legs.
Matt's torso and shoulders expanded, and grew thicker. His arms did as well, completing the look. Now he looked like a true jock!
