Paul felt the changes first, as Don's lips suddenly seemed too tight on his twitching member. Then he noticed his hairy chest was really sticking out past the edge of
Don's cheek. Quickly, he felt his body double in size, then double again.
Don realized what was happening in time to get his dad's inflating balls out of his mouth, but soon he was gagging on a big penis -- eight inches of spent rod that
stuck out of his dad and into his mouth. A bulbous pair of balls soon blocked his eyes. With dad laying directly on his face, Don tried to push him out of the way,
but the older man was just too heavy.
Paul noticed Don's own boner and struggles. He rolled off his boy and decided what to do next.
