What Tim and Kyle hadn't noticed was that while they were making love, another man was in the room.
Wanting to punish Tiffany, but not herself, Amy had decided to make a copy of Kyle before transforming him. She programmed in that Kyle 2 should be exactly like the original, except that while Kyle 1 and Tiffany were making love, he would be transformed into a pair of panties.
While Tim and Kyle were in the bathroom marvelling at themselves, Amy quietly retrieved the pair of panties. Not wanting them to be mistakenly washed, damaged or lost, she slipped into a closet and put them on instead of the pair she had previously been wearing.
In the meantime, Kyle 2 was experiencing pleasure as a pair of Amy's panties, and loved every minute that he was pressed up against her virginal body.
Unforunately...
