The (bone structure) of the fist, massages the walls of the vaginal canal in a way a cock could never do. That's why fisting is enjoyable. (when done right).
To me, it's all about the intense feeling and nothing about the visual aspect of it. (the visual aspect is more for the giver rather an receiver).
The lady will guide you on how many fingers to slowly insert at a time.
And she'll guide you when to slowly close the fingers while inside, to make a fist. Slow & easy..she'll tell you when to thrust a bit harder....AND very saturated wet hands/wrists/forearms. Make for an intense pleasure that would blow the KY commercials out of the water.
I have done it and enjoy it very much. Like a large butt plug it is something you absolutely must to work up to.
I do not really see it so much as an act of D/s, though no one would ever call it vanilla either. Not as intimate as cunnalingus. It is all the more intense for the visual to the receiver.
Good times.
