TAKING CHARGE OF HIS ORGASMS/TEASING AND DENIAL
You get to control when and how he has an orgasm. Men often respond very well to being controlled this way. It is exciting for them, and they feel very helpless and enamored with a woman who is not afraid to control his sexual release.
You start by simply telling him that he is not allowed to have an orgasm unless you direct him to, and with your permission. You can make the rules. If he is the nagging type, tell him that if he bugs you about it, you will put it off even longer. Make sure you continue to have him pleasure you, however. And make sure you let it be known that you are enjoying having this pleasure, and that he cannot have his own until you say he can.
Always remember that the closer you get him to orgasm and then stop, repetitively, often directly results in making him hornier. Timing wise, these kinds of scenes work well in the course of ONE evening (lots of starting and stopping, so by the end of the night he’s just ready to explode and will do ANYTHING for you), or over several days, with periodic teasing.
