Start with a kiss on her mouth (lips) and run your tongue down the center of her body like a ski slope, past the umbilicus, straight into the top of the nest, greeting the clitoris with a very cordial exchange of your tongue and lips, spending as much time as allowed there, sending her into a frenzy, occasionally providing hot exhalations and light blowing for ambiance before moving into the panting, pulsating dripping pussy where your polite manners begin to fade in exchange for possible tongue-fucking if allowed and if she shows glee, but always returning to the clitoris to regain composure, sort of like a home base.
During this time of her oral celebration, I like to grind and hump junior on any body part she has available or even just grab her hand and let junior grind against it to keep him hard and ready to charge in when the time is right and also to let her know that the cleanup hitter is on deck to knock one out of the park and clear off the bases from all the singles, doubles and triples that the tongue was able to provide. (although the tongue is fully capable of smashing one over the fence or hitting an in-the-park home run for your beauty)
When she has been sufficiently primed, trusting, confident, loving, happy, with as little lag time as possible, yet camouflaging any haste on your part, slide your meat in but first run your shaft by your balls the full length to the tip of your penis along her wet clit before moving into mish, beginning the forthcoming litany of myriad pleasurable positions and movements.
The pussy-licking-foreplay is more like sipping a fine champagne with little snips of caviar. Many times that foreplay if welcomed, acceptable, admired and appreciated can go on and on and on for a very long time exhausting her of many orgasms so that when your final insertion takes place, she is KO'd by the arrival and presence of your "big boy."
