My Dr Martens Triggered the Fastest Cumshot - Cock Balls Crush Trample, Shoejob, CBT, Trampling, Stomping

It's the fastest cumshot ever achieved so far! Is it because of the Dr Martens? Too much weight? Something got damaged creating the perfect amount of pain. The soles are chunky and powerful, I did not even notice the slave cumming at first. I am a bit sad I could not go on as, for some reason, he was feeling a lot of pain. I would have loved to heavy stomp but I guess it'll be for the next time... I was very angry about that. Next time will be double the punishment.
