Vacuum Masterbation

Take the tube off the cleaner and put you penis directly in the machine.
Never had a problem after using this method for years. (And I am 8" x. 5" )

I used to have a small penis, since I've been using my shop vac to get off, I've grown in length by about an inch, what's more impressive is that now I'm using a 2-inch diameter silicone radiator hose and when I'm erect, I fill the hose, I need to order a 2.25-inch hose on Amazon to get back the vibration effect back. I also get the saggy skin thing right under my head but I'm able to do this multiple times a day--going on 10-years now.

In the 1990s, I shared an apartment with two older men named Rob and Jeff. I was frequently alone at home. Rob and Jeff went out one day to look at stuff at the local Goodwill. I was a turned on 19-year-old who was bored with using my hands, so out of curiosity, I inserted my penis into Rob's vacuum hose and turned it on. It was incredible! Unfortunately, before I could finish, they returned sooner than I expected. I quickly put my penis back in my shorts and acted like nothing was going on, but apparently they saw what I was doing. From that point on, Rob would call me "Hoover" because that was the brand of vacuum he had. It embarrassed me so much that I didn't touch another vacuum for years.

I have done this frequently lately. Usually without erection. I hold my shaft and the suction is controlled there.
You can control the suction/Vibration by slightly relation you hand just a little. Granted when fully erected doesn't work welll. I usually do this after having some booger sugar, because you cant get hard anyways. It takes some learning to perfect but once you get the hang of it. It works well.

I’m totally on board with you. No bleeding in my case, but I spend 20 minutes using the brush and upholstery attachments to suck my sack, my armpits, my torso, and my boner, of course, sucking my head and shaft. Amazing! I spray some white vinegar into the hose for a sexy smell that the blower end of my Electrolux bathed me with while I suck away. The soft horsehair bristles of the dusting nozzle feel so good as they wrap around my throbbing penis. When I cum, I pump away for almost a minute, then suck up the left over cum with the crevice tool. Best orgasm ever!
