“Gosh, Ty… I come here to study biology, and I get a new body!” Mark cheered. “I don’t know what to say!”
“Well…” Ty replied, as he folded his arms before his chest. “I love watching nice guys like you grow big before my eyes… And, speaking of growth, I saw how you got bullied last week, so I think you could use a little more height and muscle in your arms?”
“What are you… OH!” mark gasped.
Once again, Mark was overcome by a powerful, tingling feeling, thanks to Ty’s powers. His arms started to inflate a little more, and he felt his strength increase while his biceps grew even thicker and wider.
“I-I’m getting stronger…” Mark whispered, as he looked over at his bowling-ball-biceps.
“You got it!” Ty chuckled.
In the meantime, Ty was getting a major hard-on just by watching mark grow bigger. He just LOVED watching his friends hulk out!
Next, Mark’s legs… Well, they just grew bigger, longer, and wider… all at once!
“WHOA!” Mark shouted, as he swung his arms sideways when he felt a powerful jolt, as his longer legs pushed his upper body higher from the ground when they suddenly started to grow. “Hey! I’m growing again!”
Within seconds, Mark had become a 7-foot-tall hulking giant. His pectorals pushed out by ten inches, forming two giant spheres of rock-solid muscle, as he towered over Ty, who was now looking up to him while sporting a raging boner.
“Gosh, Ty… “Mark grinned, as he almost needed to bend forward slightly, in order to see Ty, because his huge pectorals were blocking his view of anything or anyone standing in front of him, since he had become so tall. “You… You made me so big, now…”
“Yeah… You look great!” Ty smiled. Ty craned his neck in order to look up to Mark, who was 18 inches taller than him now.
Mark then walked up to him and reached out with his huge arms. He gently placed his hands just below Ty’s armpits, before lifting Ty off his feet like he were a rag doll. Then he brought Ty almost at his eye-level. Ty’s shoes were dangling 18 inches above the ground!
“I-I love you, Ty!”
“I love you too, big guy!” Ty replied with a smile.
“Thanks for giving me such a big body!” big Mark said, before setting Ty back on the ground. “Let’s get some studying done, alright?”
Mark sat down at the table and Ty sat down on the other side. They studied for half an hour. When they were done, they discussed what they were going to do next…
