Tied and used and dominated

I never knew before tonight that the activity of stripping naked and standing quietly as Z tied my breasts with a rope yoke and collar--making them stand up straight and pink--could get me so hot. Or that the simple act of Z bending me over and shoving his cock into my pussy from behind could make me so wet, so pleasured. Or that Z dragging me to the edge of the bed, flipping me over and shoving his cock in my throat, hard, as he thrummed my g-spot with my fingers, could make me--once again--go completely nuts.
Of course, what I loved best was his hand on my throat, covering my mouth, cutting off my air as he fucked me every which way he pleased.
Why do I love this so much?
The feeling of being dominated by Z is one of the most thrilling--and erotic--experiences I know.
