My sissy offered Me a new leather single tail. I am an expert in single-tail whips, but any new whip needs breaking in. What better target to practice on than My sissy’s exposed nipples. I will use the long single-tail to whip the sensitive nipples of My sissy until they are red and very sore. When I am satisfied, I put some painful nipple clamps on and leave My sissy to wait until I return for more.
