your story reflects my own sexual inclination
that the lady in question must be made to want at that deep carnal level. when a lover strips away every emotional protection, and she is totally vulnerable, then the sex kicks in at its most raw and animalistic.
she loses everything to the moment, nothing matters except what is being done to her and how she is being used — -yet it is what she is demanding and screaming for.
not many men have that skill. Such a man might appear selfish and rapacious, but the man you describe is giving generously of what you want. It becomes your focus and driving force, and something by which other lovers are measured.
