Everything was going great, you finally were allowed to give mistress pleasure with your thick cock, but her tight pussy felt too good, and you busted your load inside her! She shames you as it drips out. You're nervous and you've forgotten protocol and how to apologize to her! You know you're in trouble, you know what the punishment is. After all you agreed to this as a form of punishment in your contract. I hope those big balls can handle being busted by Mistress' size 11 boots! Be sure to lick them clean when you're done.
