Lock Slap and Strap

You know what to do. On your knees. Naked. You just need a chastity cage that you will put on now. Lock yourself up. Hand the key to your Mistress. You will do everything Elis asks you to do. The postures she likes, the pain she wants you to endure, the endless slaps on your balls... Everything. Obey. Relentlessly. Painfully. Now she has a surprise for you. A rubber cock. Tell her how much you want it, while you slap yourself, pathetically locked in your cage. If she likes what you do, if you devote yourself fully to her pleasure, she will make you taste this cock that you desire so much... And once she starts, it's going to last for a while...
