This was when I was first trying to make myself to keep the vibrator on my clit after orgasming. The natural thing is after you cum to relax and enjoy. I decided I wanted to see what would happen if made myself to keep going even though it's extremely sensitive. What I found out was it's insanely good and almost better than the orgasm and it's almost like it just extends it and eventually it just turns into another orgasm and you can do this is much as you want. Well, at least a girl can. Sorry boys!
