I was cleaning out he garage the other day when I noticed an old friend sitting in the corner. My old shop vac. I pulled it out and dusted it off a bit. I plugged it in and pulled out the hose. Left a nice big opening on the side. Not to pass up an opertunity, I dropped my pants and turned the vac on. Just too tempting. My cock seemed to know what was going to happen. It got hard just holding it close to the hose opening. Old memories came flooding back. It's been a while. 

I eased my cock into that dark hole and the vac took over. I had to hold it with both hands. Like holding your lovers hips. It didn't take long. I pushed my cock in as far as I could and unloaded. I should have turned the vac off, but I wasn't thinking. As I pulled my cock out of the large hose hole, The vac sucked my ball in. I almost paniced. To be honest it was a bit uncomfortable, almost painful. But after a few seconds in didn't seem to get any worse, so I waited to see (or feel) what would happen. That vac sucked my balls, pulling them back and forth. Without too much warning, I had a good hard second cum. I squirted all over the outside of the vac and on my shoes. Don't know if I want to do that again. Oh hell. I know I will do it again.
