It's hard to even think about Sue as a "provider" in the traditional sense.
It isn't even sexual so much as intensely sexually physically therapeutic.
It isn't like fucking or getting a bj. With those things, you're using your brain and your body but are still in complete control.
It isn't even like being dominated because even there their is a part of you that knows you're both just cosplaying.
What Sue does is deeply physically therapeutic but instead of being about your muscles or joints, it's about your prostate and genitals.
What Sue does is a sexual equivalent of a deep tissue massage or chiropractic adjustment.
When she edges you and massages your P-spot, your body can't help but respond in the same way a deep tissue massage makes your back muscles shift or a chiro adjustment makes your joints release.
Your body reacts because she "plays" your body and can't help to react.
When you leave, you will feel completely sexually relaxed but you won't be thinking about Sue, what she looks like or even what she did really.
You'll only be thinking about how your body feels and be slightly sore and deeply relaxed like after a deep sports massage.
And from my experience just as a deep tissue massage or chiropractic adjustment makes your muscles and joints perform better, Sue's PM and edging improves sexual performance.
I find that for the week after visiting Sue, I have a much easier time getting hard, last longer, and cum "stronger" with my SO.
It's the same way a runner runs better after getting a deep tissue leg massage.
That's what makes Sue and other high level PM providers such a unique treasure.
What they provide is sexual physical therapy.
