Roger stood up, upon feeling his butt shaking uncontrollably.
Suddenly, he saw a huge long green lizard tail sprout from his behind, splitting a huge hole in his slacks.
Roger's jaw hung.
"Holy shit." he said to himself. "This. Is. Not. Happening." HE MUTTERED. "Humans aren't supposed to have lizard tails!"
He tugged his tail, and he felt himself yell in pain, for the tail was now a part of his body.
The change was worrying, but not as worrying when he looked at his manhood, and saw that his penis had grown smaller.
of course, Roger didn't know about the tf site that his son used to turn him into a monster.
