As you put a hand on your blank crotch, Envira lands in a pile of leaves and moss at the foot of a tree.
"You little bitch!" Trying to stand up and pull up your pants at the same time, you slide in your shoes a little. "Give me back my cock!"
A muffled "No! hee hee hee" Comes from the pile as it stirs. Envira pokes a slightly bigger hand up and onto the bark of the tree. She pops up into the air, your penis jutting out from her and your balls forcing her to bend her knees as they dangle. As you get your pants up, she alights on a branch at your head height to wait for your approach, standing bowlegged over around your balls. Stroking the relatively massive cock, she shudders with pleasure and looks smugly at your slow progress.
Why is it so hard to walk? The small fairy is only ten feet away, but you find that you must hold up your pants and you're constantly almost stepping out of your shoes! Taking a moment (since Envira seems content to watch)... is she getting bigger? You watch as her legs gain stubble and her breasts change... Her posture corrects as she gains height... standing one foot three affords her the ability to stand without wrapping her legs around your balls...
And that branch she is on is higher in the air! You are shrinking! You drop your pants and step out of your shoes. Putting a hand over what was blankness, there is now a pair of puffy ridges growing on your crotch.
