Homemade Cock Sucking Sex Machine #1 (Proof of Concept)

Like if you want to see it finished and/or it being used I have more plans with this machine, some of which are detailed in the wiring schematic shown here: http://schematics.com/project/the-automotive-cocksucker-male-masturbator-47690/ Final schematic (finished machine) here: http://schematics.com/project/the-automotive-cocksucker-model-0001-57573/ Stayed up late working on this, focused on getting it to a point to where I could try it out, and yeah, it's surprisingly effective. I can't take credit for this idea, some of it (like using the syringe as an air pump) came from a video I've seen on Xtube (link to it on my Tumblr). At the moment this is just a proof of concept, a demonstration on how it works. I plan to keep improving on it. Main components consist of: -AC (110v or 220v) to 12v, 15A DC power transformer -20A PWM speed controller -Automotive windshield wiper motor -100ml hydroponics syringe -2" ABS pipe with rubber cap & bicycle tube stretched over each end
