Hi,
I've just found this video, and thought it could be interesting for you...

Maybe it's a bit soft for some of you, but for me it's quite exciting.
And a thought to Joanna's post:
For me, bondage is always a foreplay and a kind of extra "spice" for lovemaking. I get excited by it because I know my boyfriend would very soon "use" my helplessness and start to "play" with me.
(Well, maybe I should use another word instead of lovemaking... "Getting f*cked" sounds more realistic... but the point is, it's fun for me too.)
