i can take no credit for this at all, just sharing it. this was a reply by someone else when asked what kind of pics he liked to see. i LOVE this! I like in vids when the woman stands behind her slave and tells him to count to ten (when she's gunna kick his balls).. and he thinks he has til ten to brace himself for the pain.. but she tricks him and kicks on the count of 7.
I remember a pretty hot video exactly as you describe, done by a Mistress Vixen some time ago. She had a beautiful voice and the cutest laugh after she'd kick her poor victim. Wish I knew where any of that was.
