Ty grinned at Ian, realizing that the way he'd worded his wish, everything had gone in stages and stacked, so that when Ian grew taller, he was enlarging an already enlarged dick and muscles. He was now 7'9" tall, but with a dick over a foot long, and was more than 30% more muscled than he would have been if he'd just grown taller.
"I wish you'd remember your new clothes, Ian," Ty said, still grinning. "It's not like you just suddenly got this growth spurt."
Actually, it was just like Ian had suddenly got this growth spurt, but Ty's wish winkled its way into his mind, making him think that the massive growth had been over the course of the past couple of years. Which was still pretty amazing, but not as much of a freakout.
"Yeah," said Ian, looking down at himself, noting his massive cock. "Wonder if I'm going to grow anymore?"
He started to think about jacking off, and how it took both hands now, and with that, his cock grew again, over an inch, then his muscles began to massively fill out even further. Then he started to grow taller until his head touched the eight foot ceiling and he started to hunch over. Not that he thought this was anything unusual.
Ty did his best to keep a straight face, watching as Ian was obviously still thinking of jacking off, his dick growing from the 15 inches it was with him at eight and a half feet tall up to an amazing sixteen and a half inches, his muscles rapidly growing more massive, and then his height increasing until he was almost nine and a half feet tall with an eighteen inch cock. The shreds of his old clothes were hanging off him.
"God, I'm a freak," Ian said. "Not much to do but sit in my room and jack off." His cock sprouted again, going to twenty inches, and he his muscles bulked up more, impossibly massive, and then his height inched up to just over ten feet tall, hunched over in the hallway. "Wish I'd stop soon. My cock's almost two feet long." Which it was, just a hair under 22".
Ty grinned. "You don't want to stop now?"
Ian thought, remembering the past couple years, and his strange, massive growth. "I don't know. It's kind of weird. It's almost like you set yourself a goal. First you get to say you're a seven footer. Then you say you're an eight footer. Then you're suddenly ten feet tall, but you don't want to lie and say you've got a two foot cock when it's actually a bit shy."
"Measured lately?" Ty asked.
Ian thought about it, and as he did, his cock inched longer, growing to just over two feet long. Then his muscles inflated more and he started to hunch over further in the hall as his height grew to 11'4". Ian grinned, "Actually, it's a bit over. Wish I'd stop growing though. Taking a ton of my basketball salary just to keep me in clothes."
"Sure thing," Ty said, wishing that Ian would stop having his cock grow and getting taller ever time he thought about masturbating. Ian put on his new clothes awkwardly in the cramped hallway, his muscles continuing to swell until Ty wished for them to stop also.
"Hey, happy birthday, Ty," Ian said. "Good to drop by the old place. I got a new apartment with twelve foot ceilings. Fits me, if just barely." He waved his massive hand and shambled down the stairs with his enormous size 38 basketball shoes. "Drop by sometime."
