Use this opportunity to explore her whole body, making your way back to her vagina every few minutes to keep the heat turned up. While in exploration mode, talk to her. Tell her how hot she makes you. Tell her what you want her to feel, and how you plan to get her to feel this way. Use this time to compliment her and make her feel special.
Remember, the vagina is a complicated and misunderstood part of the body. It takes more than just thrusting in and out, to get her to reach orgasm. The power to make a woman climax is one of the most powerful skills a man could ever learn. It takes the right words and the most sensuous touches. Many men never master the art of bringing a woman to orgasm. But once you do, you may have your woman totally addicted to you. So use this skill wisely.
When she feels wet enough, begin to stimulate her G-Spot. Use the same motion you use to motion someone to you. Interchange the pace, get faster at times, then slow things down. This will keep her, and her vagina interested so that it swells with pleasure.
You’ll know when she is in full orgasm by feeling her vagina begin to swell and pulsate. Go with it, but never ask her if she had an orgasm. You will just know.
