He used to be very rude (in the past).
There was something impolite when we were exchanging some emails. (I’m half joking.) It made my punishment on that day real punishment. The canes I’ve been using in my regular sessions are not specifically designed for BDSM. I go to a rattan wholesaler and ask them to cut rattan for me. Since I purchase them cheaply, I get many pieces.
Therefore, if it gets blood, I usually toss it out. So there is nothing you need to worry about. Y
