- you don't need all holes or lube. I use a piece of PVC that leaves a little clearance, this allows the skin on the shaft to reverberate and makes me cum. i keep it in a bucket with all the other shop vac accessories. Be sure you sand your end smooth. Insert the vac hose in the other, (make the pipe is long enough) i wrap a rag around the gap to control the amount of suction.

- i use mine when the wife is home and i'm "vacuuming the car" or home alone, I'll stand behind the workbench getting sucked off and watching the world go by.

- made one the other day, intense cum! I consider myself average (6"long x 5" girth) and 1ft of 2" pvc works well. tried 1.5" but swell quickly and stops the flutter effect. regular shopvac works best. don't need all the holes shown but do need several small ones down the shaft. u can cover them with your hand as needed to control the suction and vibration. don't forget to sand edges and the inside of tube where holes drilled.

- I use a 5hp shop vac with a piece of PVC pipe on the end. I drilled holes in it and my cock will vibrate intensely while I drill my ass with a huge dildo
