The next time your husband asks for a blow job, oblige.

When you get close to bringing him to orgasm, let him know that this will be the last time he ever gets a blow job unless he kisses you deeply after you finish him.  At this point he will almost agree to anything for you to finish.

When he does finish, if he chickens out, do not ever give him a blow job again.  If the time comes and he is really desperate, remind him of your pact, hold strong, and say you won’t do it unless he follows through this time.

If he says yes, say to make sure he does not chicken out, that you will only do this if you can truly tie him up so that he cannot get out.

Then bring him to orgasm, but pull your mouth off as he is doing this, and let him ejaculate on himself.  Scoop up the cum, and feed it to him.  Reward him after you have done this, and let him know that from now on,  if he wants a blow job, those are your terms.  Eventually, you can even get him to crave it.

Get him some self hypnosis mp3’s he can listen too, that will help him with this.

Here is an audio instructional story of how to make your man eat cum.
