The underlying rationale for Speed Seduction is to make the chick feel something, to give her some romance, to take her into another world that is not as boring as her current mundane life. This gets her wet, makes it more likely that she will drop her deals and makes it easier for her to fall for you if you're looking for an LTR.
Mature men on this forum will remember something called "sweet talk" which was and still is the best way of getting laid. Speed seduction is just another form of it.
Chicks need and want romance, especially older women. Not the "give her flowers" romance but the "make her feel something" romance. Rapport, excitement, escape, anything (but horny is better.)
Your girlfriend needs it as much as your ONS needs it.
