This is the most difficult time and you'll really have to stimulate yourself. After the third or fourth orgasm, you'll be coming dry, and you'll notic... a new sensation. Firstly, you'll be able to keep on having orgasms (within reason of course) and when your cock goes into dry spasm the sensation will be deeper and much more sensual than your sperm laden orgasm. My theory is that without the need to spurt, your orgasm is now more like that of a woman's as it is my experience that when females. "Well if she's the one lad," she said patting my hand.

Man when I hit home it was great. She started moaning and twisting and turning. I was no dummy. I went immediately to sliding those sexy little bikini panties off. This same girl who before had never let me get any closer than rubbing her through her jeans covered pussy, actually lifted her delicious little ass to assist my sliding her panties off.Soon I had two and then three fingers up her twat. I was stretching her out in fine fashion and she was getting hotter all the time. But I noticed.
