Many women have only a basic idea of how to give a man a good blow job. Most seem to think that by closing their mouth around a mans cock and bobbing their head lustily up and down as fast as they can until he shoots his load constitutes a good blow job. This is true to a point and all well and good for a quick blow job in the car or under the office desk when time is limited. If you want to bring him off quickly then this is an extremely satisfying way, but what does the man's cock really want? You should pick a time when you will not be disturbed in a reasonably lit area so that both you and he can see what's going on. Overcome any shyness that you may have and let him see his cock disappear deep inside your mouth, observe and make a mental note of the responses from his cock and indeed the look of pleasure on his face that your tongue and lips are providing are the first steps to master. Pull his foreskin down to reveal his corona and run the tip of your tongue around the base of it.
Close your mouth onto his cock and flick the underside of his corona with your tongue. Talk to him, tell him his cock is wonderful and that you are not going to stop until he cums in your mouth. Always stay in control and don't ask which part he likes best, find that out for yourself. Keep your tongue, mouth and hands active. Cup his balls and gently scratch with your finger nails the area between his anus and balls. If you are wary of the amount of cum he will produce, just as he is about to erupt, place your thumb and forefinger at the base of his cock and gently squeeze to restrict the flow. The amount of cum a man produces is a good indication of how much he has enjoyed what you have done for him. Most men who have been stimulated in this way will produce copious amounts. Slow down and relax are the golden rules.
