How does it work?
The top bar measures the speed and intensity of the connected vibrator.
The bottom bar measures the pressure of an inflatable butt plug.
As you approach orgasm, your hole involuntarily clenches, signaling the device to shut off. After a specified time, it begins to ramp up again. Repeat. Repeat. Repeat.
So, does it work? Just ask @PupHobbes, though, after 2+ hours in the machine, he probably won’t be able to respond in anything but barks and whimpers.
