OK. Getting big didn't scare Adam. Simon frowned, watching his brother keep stroking the big cock. Then he grinned. "So, you like a big cock, huh? You ever see the movie Flesh Gordon?"
"Hey? Who the fuck are you?" Adam scowled, not recognizing the older version of his own brother. "I'll beat you to shit!"
Simon pointed the Chronivac at his brother, punching in a totally new set of instructions. "Oh, I don't think so, Adam. Simon says you're a Penisaurus!"
"Simon?" Adam blinked, finally realizing it was his own brother, but then gasped as his cock swelled out even larger. "Oh, fuck!" The shaft stretched out and thickened, a foot long, fifteen inches, twenty. He was so busy staring at his crotch that he didn;t notice the rest of him was shrinking. His legs were getting shorter and thicker, skin sagging and getting wrinkled. But not with age. the muscles and bones were shanging into softer tissue.
Adam staggered and then sat down on the floor as his legs gave out, but all he was paying attention to was the now three-foot long, foot-wide cock. His hair was falling out and his upper body looked like it was melting. His legs lost all bone, and were now obviously changing into massive testicles.
Moaning in pleasure, Adam reached up with his shrinking arms and pulled down the heavy foreskin that covered a shaft taller and heavier that the rest of his body. He looked like an ugly 5 year-old now, head dropping into his shoulders. The ballsack was filling, strecthing as more of Adam turned into cum. His eyes widened in sudden fear, but his scry was cut off as the last of his body and head got sucked into the cocka nd balls.
Adam was now a five-foot tall, three-foot wide Penisaurus, a true monster cock. It shuddered and then twisted its huge flare to face Simon.
