Some of the most intensive O's I've ever had have been through skilled prostate stimulation combined with HJ or BJ. There's nothing quite like it!

Prostate Milking is the ultimate oral of going to heaven and back. It goes up against the male G-Spot so there are two different sets of nerves that are triggered when reaching the big O. I consider it one of my specialties. If you read some of my reviews you will get an idea of what it is. Basically it takes a 2 hour session to get to know the person to  develop trust and relax for the first time.

After that it is a piece of cake. I have to get to know your body, things do have to go slowly, at first and once I am able to get you to relax I can take you the edge and back before you release. After that, well, you are in heaven, and I doubt you could care about anything at this point. The body in males does release a double wamy to the brain, and I assure you, whoever told you about this is correct.
Thanks for sharing, Kelley White

I use a long finger-like sex toy with ridges where the finger pad would be and (using lube of course) I slowly move it on the prostate back and forth while playing with the man's cock with my other hand until he climaxes.  Its a very nice and slow rhythm and my clients love the intensity of their orgasm.  Its a deep release.
