A very good question !
The feeling of being exposed was always erotic for me, even as a youngster.
As a matured adult now, it is equally exciting still and as the requirement of my giver of enemas, to have me begin on hands and knees fully exposed so that she can lubricate my bottom sufficiently for the insertion of a very long tube, using her delicate loving fingers, sends me into orbit each and every time, almost as incredibly as in the first time, when it felt so special.
To this day, I am still unable to describe adequately, just what it is that so affects me this way. All I know, is that it is just as strong a sensation both physically & emotionally now, as then.
When she parts my cheeks and tells me "just a little bit more I must take" (of her exposing that tight hole and pulling my buttcheecks apart) several times over & over again...it is all I can do, to just contain my emotions and not allow myself to release something I do not want to, too early, as I know that I am in this for a long while before the end will be here.
Yes, being exposed with that cool air down there and all that attention and delicate touching. Well, it is something to behold for sure !
Must I endure this time & time again ? I will then, do my very best. I thank you.
