Part of the skill is being vague and using sexual metaphor - 'open', 'penetrate', 'come inside', 'surrender' , 'feel a powerful happiness', 'below me', whatever. Anything else, I don't think so. Modulating the tones of one's voice is another facet of the speed seduction technique. This basically involves putting on a deep, mellifluous voice and speaking slowly and rhythmically. No, your sexual technique must be enough to do that.
Body language is also important.
From what I can gather this mostly consists of pointing at your crotch a lot. While you may have your doubts, there are plenty of people willing to testify that speed seduction works. Jeffries' website receives 85,000 hits a month and is littered with eager testimonial. He probably came in his pants right then and there. Well, technically if you usually have sex with your hand and you get laid once, that is enough to fulfill that statement.
