Ruin it for me Slave. Ruin what could have been a really good orgasm, show me proof that you can follow my orders. Now climax for you, slave. Show me the pain instead of the pleasure. Show me the sacrifice of that orgasm. Hit and grab your balls, squeeze the tip of your dick and push in while you cum. You can do it for me, right? Otherwise you are not slave material. You want to serve me, this is one way to do it.
