One time I was riding the school bus home and my buddy said he overheard his dad tell mum to suck his dick. I was like wtf does that do? He was confused too. Anyway, my family had a central vac system in the house but inside each hole in the wall were two lil metal nubs. The vacuum hose has a metal ring around the end that connects that circuit and turns on the vacuumage.
So I thought that thing could suck my dick. But how do I get metal in there? First I tried fucking it with a spoon. That was goofy. It would turn on for a second but it didn't really feel great. I put the spoon back in the drawer and tried other various paper clips and shit. Never got it to work right.
