8 XXX : BdsmDIY

Modified our favorite toy by drilling a hole down the center. The tip has only a slice with a knife so that it closes up when no fluid is coming out. Attached to 12v powered peristalsis pump which will be driven by arduino providing pre-cum throughout long sessions. Will post more detail as the project gets finished up!
What fluid is actually being pumped?
Well... that's hot. I'm impressed! What did you use for the fluids?
Love it
Be conscious of your tube routing. I assume it isn't finished yet, but you don't want any places where it rubs against hard wood or plastic. You could end up damaging the tube and have to replace it.
Omg! Yes! Please! ❤
Thats awesome!
Did you build the machine yourself, too? I'm at such a project at the moment, and I'd need a few numbers, if possible :)
They sell dildos that do that already.
