Sucking Toys?

Anyone got any toys that actually suck their penis?

I keep seeing TEMU add videos that show a device sucking on butt plugs that are about the girth of an average penis & I'm intrigued by the adds. What do you all think?

I have made a few sucking toys/machines. I am a retired Chartered Electrical Engineer and like to keep my skills up to date. My best machine consists of an electric air pump which is controlled by an Arduino Uno board. In continuous mode the pump tarts up and runs until it reaches the set vacuum. In pulse mode the pump runs until it reaches the set vacuum then switches off. A vent solenoid then opens releasing the pressure for a set time period (0.5 to 3 seconds) then closes and the pump starts up again.

I have various receivers that plug into the pump that fits over my penis, my testicles or breasts.
