Ty couldn't help but laugh as he watched Dustin, drenched in his own cum, start to grow larger, still. As his brother groaned and gripped the base of his massive, two-foot cock with canteloupe-sized balls, Ty could just hear sounds outside from his neighbors.
Probably reacting to the cum fountain that he'd created out of his brother over the past quarter-hour, he thought. Closing his eyes, he concentrated and felt that part of his brain that held his power reach out to the reactions of his neighbors and "turn off" their awareness of the puddles of ejaculate that were just about everywhere. Just for fun, he also tweaked his hyper-hung neighbor, Jeff's, sexual desires, sending the man running to his bedroom with his confused girlfriend on his heels, still trying to figure out what he was trying to hide in his pants.
Ty knew.
Ty nearly wished that he could watch what happened next in the house next door but -instead- he focused on his brother.
Indeed, Dustin's cock already was over three feet long and thickening as fast as it was getting longer. His weary brother moaned at the sensations, his hands stroking along his cock helplessly while Ty watched.
"God, Ty... Please! You said you weren't going to do stuff like this to me..."
Ty corrected Dustin. "I said that I'd occasionally play with you... I just won't do shit like that I did to Mark and June, to you..." With that, Ty sat down and concentrated on the roof being fixed and the cum, outside, soaking into the surrounding lawns to fertilize them.
Dustin continued to moan as his legs were pushed further apart by his growing balls and endowment. Soon, the teen was looking up at his massive, tightly-pumped cocktip as it loomed a couple feet over his head! It pulsed, idly, and sent a huge, thick stream of precum flowing from it's tip down the length of the shaft while each of his balls swelled to the size of beachballs! "Ty... It's ... it's making me hornier..." he complained.
Ty nodded. "Sure is..."
"Please! I'm practically all cock, now!"
