I sat in front of the computer screen pumping my cock in my hand to the order of my blackmailer, my mistress who watched from her bedroom. As we lived several hours apart we couldn't see each other on a regular basis so she'd decided to begin her domination over me using computers and webcams.
"That's right bitch. Jerk that cock faster now. Don't you dare cum!" she commanded.
My young dominatrix Miss Danni, who just five years ago had been one of my students when I was a teacher at a middle school, was wearing boy shorts styled underwear and a tight pink t-shirt which showed her midriff. She never took off all her clothes. "You get naked for me bitch, not the other way around." she'd say. "You're lucky I even turn my camera on and let you see me."
This time around Miss Danni had me sitting on a chair in front of my computer, completely naked and jacking my cock off for her. She claimed she was recording me, I didn't know if she really was, but I didn't want to risk doing anything that would cause her to release incriminating evidence of me to the wrong people. Several weeks ago Miss Danni had tricked me into taking a series of photos making it look very much like I had raped her and captured the event with a camera. She was in sole possession of those photos and she'd done it just to gain leverage over me. She wanted to torment and control me, and I was very much in her control.
"Mistress please, I'm going to cum. I'm going to cum!" I panted as my hand flew over my sore penis. Miss Danni only sometimes let me use lube and she had me playing with myself over and over. She also never let me cum. She insisted I would only get to cum when I was in her presence.
"Hold it bitch. I'm going to give you the count of ten and then you can stop. Keep that hand moving and don't you dare cum." Then she proceeded to countdown from ten to one. She took her time and I contorted my face and wriggled my legs straining with everything I had to not cum. Finally she reached zero and I was allowed to stop masturbating and not a moment too soon. As I let go just a few drops of cum leaked out the tip of my dick. My orgasm was there, all I'd have to do was move incorrectly and I'd be unable to stop my balls from emptying their contents. I breathed heavily trying to relax and keep my cum at bay. Miss Danni laughed maniacally at my consternation.
"Awe, did wittle baby dwibble a wittle cum?" she patronized me. "I'm afraid someone will have to be punished for his missbehavior. My bitch knows he's not allowed to cum. First, though, get the ice and get rid of that erection, I don't want to see it anymore."
"Yes Miss Danni." I obliged. I reached onto my desk and grabbed the bag of ice I'd had ready. Every time Miss Danni finished commanding me to do things for a night she'd make me hold a bag of ice on my dick until it went soft. The main reason for this was so she could see me put myself back into the chastity device she had told me to purchase. I also had to buy dozens of little plastic locks. Each one had a serial number on it. Each time I put the device back on Miss Danni would have me hold the lock up to the camera so she could write down the serial number. The locks had to be cut off and she'd make sure the lock I showed her when I removed the device matched the one I'd last put on.
