Spanking The Slave Girl

I order the slave doll to bring over a chair, for me to sit down on, then I take off her T-shirt and her pants - I want her butt exposed for the penalty thats coming now! I put her over me knee and begin to spank her butt - some stiffer, some not as hard - but over time her butts going to become bright crimson! After the very first few slaps you can already see the imprints of my fingers on her ass cheek - and the slave girl is moaning in pain with each hit! But that was only the beginning! She told me before she was freezing - well, I know at least one body part that wont be freezing anymore soon! Again and again my hands hit her butt until it is glowing red!
