With his cock so hard he looks around and sees Jen laughing at her little task.
His legs are so long that in a single bound he is so near her that he is able to grab her and impales her on his now massive cock. It doesn't just go to the tip but all the way through her and out her mouth. She can't yell or scream or say a single word.
Kyle said to her, while pistoning her up and down his 19 foot cock stimulating every single inch of it, transform or dare.
She couldn't respond and he kept moving her up and down. He was really enjoying this and as the time ended he said you get both.
For your transformation your tits will grow one ton for every foot in height my cock is. For your dare I dare you to change me back to my normal self but leave my cock 19 feet 6 inches but only when it is hard.
