See this timer? It's set for 15 minutes. You owe me three orgasms or more before time rings out, and I'm going to make you give them to me...or else. Once the timer begins, your cock is my mine, and I'm going to milk it dry before these 15 minutes are up. Stroke HARD. Jerk your brains out. Show me how fast your cock can explode, and then keep going. Drain those balls for me and don't stop. There's no need to savor the orgasmic build-up; I just want you to cum. Don't think, CUM. Cum for my shiny stockings. Cum for my hot harness lingerie. Cum, cum, CUM! You're my cum pet. It's non-stop masturbation for you -- except for when I pause the timer to mess with you, and I am going to mess with you. But you'll cum for the challenge. You'll fill your orgasm quota and even milk out some extra loads if you're a masturbatory overachiever. I don't care if your cock is tired or flaccid, you'll keep cumming. You owe me three orgasms, and you're going to give them to me...or suffer the penalty.
