As a top, I LOVE fisting and anal stretching. And "pegging", and prostate play, and... you get the idea. I could gush for hours about it.
My primary fetish is depravity, and anal play hits all my buttons in that way. It's also really cool to see what the human body is capable of, stretching (heh) it to its limits.
Contrary to its portrayal in porn, It's an incredibly intimate act that requires a lot of trust, patience and skill. I am always aglow when I receive demonstrations of devotion and trust from my submissives and bottoms. For those of you that have never fisted someone, you should know that you can feel the bottom's heartbeat when you're in there!
Aside from all the sexual gratification, I always have a swelling of pride and appreciation for my bottom/submissive/playmate when I finally get that last knuckle in and slide the rest of the way in.
I have always wanted to fuck someone with a baseball bat, but haven't had the pleasure yet...
Talking about this is making me want to go watch some porn with Belladonna in it
