After school Jenny went home ready to try some new things. First she put a soccer ball in each boob and then hardened then with metal. Then she removed the balls and laid down on her boobs. They weren't solid but were quite firm, though still a bit squishy.
Then she had a fantastic idea. She went out to the garage and used the skills her dad had taught her in the shop to build a fun contraption.
First she built a frame with two pulleys on it. Then she made a few hooks out of metal and wood. There were single hooks, double hooks like an anchor. Triple hooks like a grappling hook.
She screwed the frame to the ceiling and ran ropes through the pulleys to an electric motor on the wall that had a remote and timer she had soldered on.
After weight testing it she lowered the ropes, placed a pad on the floor just in case, and hooked a single coated, metal hook in each nipple.
Slowly she raised the winch till she could see her boobs deform a bit, though they were still quite firm. Then she lifted herself off the floor, and slowly fell asleep thinking of all the changes from the last 3 days.
