No hands cum-no prostate stimulation!

I discovered yesterday whilst cleaning the patio with my pressure washer, that the hose that joins the machine to the trigger vibrates very powerfully and at a perfect frequency. I held it against my cock and within about a minute I was literally coming in my pants! Fortunately the pressure washer is so loud, my neighbours didn't hear me groaning and grunting with pleasure:) Some anal stimulation would have made it extra nice.....
