I know you are a little afraid of your Mistress generosity. Because you had to learn already Mistress always makes you tip for anything she allows you. Mostly with cruel fun. Well, funny for her. Cruel for you. Are you trying to outlast? Again? You know there is no way to outlast Mistress if she wants you to feel that intense frustration. If she wants you to cum ruined, she makes you cum ruined. There is nothing to decide for you. Anyway, how long could you possibly stand her warm oily hands and that amazing view over her long pantyhose legs, her curves, her tempting red lips with that devilish sweet smile when she makes you suffer for her pleasure. So just let it happen. Cum ruined for me.
