Extreme egg swings - user slave as a guinea pig for weights

I wanted to try out what else my training weights could be used for. So I tied the balls off my test object tightly and attached the weight plate to them, then it was time to get up and swing the balls. Was probably a bit too much for the slave pussy. Well, for that he deserved a few more hits with the new whip, which ended in a fit of laughter. Had fun with it. Do you think the weights were too much the way I dropped them or is there more?
