Cum TWICE to escape!

[Like Ra]

Another version: try NOT to come, or the bondage time will be increased. The challenge is the same - how to detect subsequent orgasms.

Oh man, that’s just evil...

this project uses an inflatable butt-plug and a pressure-sensor to detect an approaching orgasm:

Wouldn't it just be easier to measure the resistance over a piece of fabric that absorbs the cum and to let loose once the resistance drops below a certain value?

Sensors exist that you can just put a piece of tubing through it and it can sonically detect flow without even touching the fluid. With my device that captures cum and pumps it combined with one of those flow sensors, it should be able to detect orgasms decently reliably with the right program. I would build one but I'm just not that good at programming or electronics design.
