"Well that's a start," I said as I finally stopped whipping you. You might have offered to trust me but I wasn't so easily convinced. Besides, after the hard whipping it's time for you to try something different. I walked over to one of the tool cabinets behind you, and when you strained you neck to see what I was doing you could see that I was pushing a strange-looking device towards you. "This is a Sybian machine," I explained, as if that would mean anything to you. I had replaced the dildo on the machine with just a ribbed surface, and you watched wearily as I positioned the machine between your legs. "Sit down on it and don't move," I said as I began lowering you by the ropes by your wrists until you're straddling the Sybian with your pussy resting on the ribbed surface attached to the vibrating part. I could tell that it hurt when your pussy touched the surface, but by now you already knew better than to disobey me.

Next, I took out a pair of heavy steel clamps. When you saw them, you started crying and babbling again, but it was unless, and you cried out in pain when I pressed one against your right nipple and slowly let it close. I pressed to other one against your left nipple, waited, and then let it snap shut. You're sobbing pathetically by now, but your sorrow was far from over yet. I tied a string to the end of one of the metal clamps and passed the string through a D-ring at the front end of the Sybian. I then tied the other end of the string to the other clamp. I made sure that the string was short enough so you're not only unable to get up from the machine; it was short enough to be taut all the time. With your wrists still tied, even though you're leaning forward as much as your could, your tits were still pulled into two cone-shapes. "You try anything funny and you'll stay in this pose forever. You hear me, cunt?" I said sternly.

Then, standing before you, I unzipped my jeans and took out my cock. You tried your best to hide your disgust when I slapped my cock playfully against your face. "C'mon slut, take it in your mouth and show me what a good little cocksucker you are! Oh and just to be nice, I'm gonna make you an offer. I'm going to switch on the Sybian, and if you can get yourself to come in less than three minutes I''ll untie you," I said as I switched on the machine and set the speed to "low". The truth is, I was quite sure that you wouldn't be able to come so quickly. I just wanted you to try to relax and gave in to the machine's stimulation, and once you'd done that, there's nothing you could do to stop it...
