I'd let him have his unlocked cock buried deep inside me

I've always believed that no matter how much you abuse, punish or deny your slave, it's vital that you keep your word & deliver on any promises that you do make to them - although of course the devil is in the detail ladies.

I promised him that if he suffered through all I a sked of him, I'd tie him down, let him have his unlocked cock buried deep inside me & fill me up with his cum.

Of course tied like this there's no wav he can perform any kind of thrust or get any penetrative pleasure at all, I'm pushing my ass down as hard asl can to painfully squeeze his balls & using the biggest dildo I can find to give him the most painful milking of his life. Promise delivered, it's not my fault if it's not all he'd hoped!
