For the quickest orgasm, watching/listening to others masturbate, male or female goes a long way for me. as does masturbating on my mic. Often, but not always, I will climax fairly quickly. Its a big turn on when ppl are listening to me enjoy touching myself. in fact, i hve had multiples on mic. hard to achieve any other way.
kissing while being rubbed/touched also pushes me over the edge. i lve hubby doing that
