What do you think of this fucking machine?

The base is just a 4" × 16" wooden board.

I mounted my favorite dildo on one end of the board. Then I placed the board on top of a ball that acts as a pivot. By pushing down on the other end like a lever, I can move the dildo up and down at whatever speed I want.

Another thing I really enjoy is that when I'm fully seated on it, the repeated motion also rubs against my penis and balls. Any precum that drips onto the board is easy to collect, and I like licking it off afterward.

Credit to @smoozzy20 for the original inspiration. This is just my own DIY version built with easy-to-find materials.

I hope I explained the idea clearly.
