Your cock is rockhard for your mistress

Your cock is rock-hard for your mistress. Do you like this, my obedient sub? Good. You are not permitted to touch yourself. You are doing well. Good boy. I can still feel the hostility you have for this, but it’s getting harder to outlast your mistress. Every time you hear your mistress’s sub call you a good boy, you feel a wave of euphoria and extreme arousal wash over you, taking over your mind and body completely, under the mercy of your mistress. Do you understand me? Good boy.
