The one to try to destroy the dildo first would be Margaret.
After Laura left the garage, Margaret picked up the saw and hovered it just above the sex toy. She took a deep breath, then began to cut it. One slice in the middle, cutting it in half. She braced herself for something to happen, but nothing did. She wasn't a sex-crazed maniac like Grace had become. Maybe this could actually work after all.
She hovered the saw over the middle of one of the cut pieces and was about to cut, but stopped when she saw that something was happening to it. The piece that she was about to cut was basically just a cylinder of whatever the thing was made of. The other piece was the one with an end looking like the head of a penis. Now the piece that she was looking at was developing its own "penis head". So she had essentially created two dildos by cutting the original in half.
"Laura, I've got a problem here!" she shouted, panicking.
As she did, she watched in horror as both dildos grew longer, becoming as long as the original. What had she done? Now there were two of these things?!
