You are nervous and stare at the ape man's empty loin cloth hanging from the branch opposite you. The ape man's hot breath is on your neck. Then the loin cloth starts twitching and moving of its own accord. It is getting larger and larger and its starting to look human. Then it fell off the branch where Tarzan hung it. The thing falls in a heap about two feet from your bed.
A sweaty dirty naked young man gets to his hands and knees and grins at you.
"Damn, after two months, I thought the court wouldn't ever send anyone else. Then I kind of lost track of time. What's the date anyway?"
Startled you reply, "December 18, 2013."
"December? Well that's only - wait 2013! I've been that stinking ape man's loincloth for nine years!"
"His loin cloth for nine years?"
"Yeah, well, now it's your turn."
"Umpf!" you say as your head disappears under the covers as you shrink to wrap the huge ape man's manhood and buttocks.
"Come to bed, Jane!" the ape man says.
The former loincloth lets out a shriek as size a pair of DD boobs erupt from his chest and his cock and balls burrow deep inside his own crotch.
