I defied my Master’s orders and masturbated last night, even though I know I am not allowed to cum without his permission. I don’t know how he knew, but somehow he did, and he was very angry with me. He handcuffed my wrists and ankles, then had me bend over where he attached my ankle chains to the floor. I wasn’t sure what he had planned to punish me with until I felt the leather flogger hit me hard across the ass. He made me tell me what I am while he hit me. “I am your whore, your slut, and your cum dumpster.” He made me repeat it over and over after each hit with the flogger. I was shouting it through tears by the time he was done with me. I was shaking and quivering in pain once he was done.
