No, But Something Has Changed

"What the fuck dad" Cam said, not believing his dad could have just said that to him. But then Sam, his identical twin brother, turned around and Cam saw it before he could advert his eyes. He saw the moist, alluring slit between his brother's hairy legs, something that certainly didn't belong there.

"How is that even possible?" Cam said stepping closer to see it better. Sam, suddenly embarressed covered it with his hands.

"I somehow have one too" His father said.

"What?" Sam said as Cam decided to inspect his own groin. He pushed his hand down into his pants and was amazed by what he found. He certainly still had male parts, only they felt twice the size of before. Not thinking, he striiped off his pants and boxers and looked down to see for himself, his cock growing semi-hard in excitement. It was now easily a foot long, if not longer.
