You've been such a good pain slut, following my sadistic commands over the past three grueling videos of this series. Now it's time for your reward. I'm FINALLY going to allow you to cum. I'm a fair and generous Mistress, and I think your suffering has earned a release. BUT - not until you are subject to one more round of torment. Yes, I'll still be brutalizing your manhood, but this time I'll allow you to edge throughout until a powerful orgasm at the finish line. Let's do this!
