You've been a decently behaved slave so I thought I'd give you a little treat: Granting you permission to jerk off and cum. You must be so excited! But wait - of course I'm going to make it more fun for ME than it will be for you. So here's the deal: You can jerk off and cum but you CANT STOP jerking off until I say you - Which will be way passed the point of your orgasm. That's right - I'm going to let you cum but then I'm going to make it unbearable for you :)
