I enjoyed being the giving end. It's like a taboo type thing, which makes it so much fun. Its all about trust, and giving one's self over to the other person I think.
I loved giving her a new sense of pleasure, especially when she seemed so suprised that she actually enjoyed it.
Not sure if I would like to be on the receiving end though, last time I looked, my ass is a bit too hairy for that, and i'll be damned if I am gonna shave it.
