I told you not to call...
I told you not to call unless it was an emergency.
No, being so horny you think your balls are going to explode is not an emergency. You've been saying the same thing for weeks.
Of course I won't let you come; why would you even ask? You know what? I'm canceling your birthday orgasm, and if you bother me again without a good reason, you can say goodbye to Christmas as well.
