This time I am not going to write a story... Instead, just what happened. Most of you like strong stuff and I need to try new moves when I can. This session, while using this pair of Converse, gave me the opportunity to test slave's limits. After the session I noticed the cock was severely bruised below (the part touching the board), and some red dots appeared on the skin as well, meaning that probably I've put a lot of pressure. I used lubricant at the very end, so I had fun trampling while having a firm grip with my soles. My goal is to do the same with heels and other heavy boots… one “step” at a time…
