Dirk filled a few old plastic water bottles with piss, and deposited loads of cum in 3 magnum condoms. Hours had passed, and Chad remained in the dark in Dirk's gym bag.
It was after 11PM, Dirk's family was asleep. His vibrating alarm prompted him to action. He had meant to sleep, but found he was too excited. He set up his video camera on the tripod aimed at the blotters on his desk.
He lined up the condoms and bottles of piss. His shorts were tented in anticipation. He took Chad out of the gym bag, but left him in the baggie.
He had a notepad with several experiments outlined. The first was to check whether Chad's size could be altered by the transformation. He initially planned to put the pink urinal cake in one of the cum filled condoms to see if the confines of the condom would produce an action figure sized cock slave. But the condom was tight and colored, so he considered using the plastic baggie instead. He would get a better view. He could always pour piss on Chad, and put him in condom or in the baggie to see if there was a size difference. But only if he remained tiny, if he grew. Well, a couple doses of cum and a lot more piss should have Chad on his way to becoming Dirk's slave.
