I have been pumping for many years now. Almost everyday, and found it getting rather dull, boring...bla bla bla. Well I decided to try something different, I slid one of my metal sounds in and very slowly pumped up, until I had a good seal. Man did it feel great, and my dick was harder. I found that I did not get the "mushroom" near as bad. Wondering if anyone else has pumped using sounds at the same time, and did you get a different result?
