A word to the wise when doing self bondage - always check, re-check and then check again when setting up! My last session turned out a bit more extreme than I expected.I have made myself a bondage chair which spreads my legs apart. My ankles are strapped to the chair legs and my legs just above the knees to the bar I sit on on each leg. My waist and chest are belted to the rear pole and so is my head across the forehead and chin.I'm dressed in my full rubber catsuit with a pair of rubber pants with a built in cock sheath under the catsuit. Over the catsuit I have a pair of rubber stockings which are held to my corset with some very strong suspenders. The corset is heavily boned and restrictive. I have a rubber hood and a neck corset with attached head harness ball gag. I also have a pair of rubber shoulder length gloves over the gloves of the catsuit. On my feet I have a pair of 7" heeled lace up oxfords. These are just about walkable in but very challenging.I inserted an inflatable and vibrating butt plug and pumped it up a couple of pumps to keep it in but not be too uncomfortable.I skootched onto the chair and began strapping myself in. First my ankles then the straps above my knees. Next up I used some electrical tape to fix my rubber clad cock to a magic wand vibrator fixed to a stool set between the chair legs. Then I fixed the waist and chest straps. I strapped in my head at the top and bottom and all that was loose now was my hands.I had a pair of locking wrist cuffs on. The left just had a clip link on it, the right had a chain about 15cm long on it. I had placed eye bolts at the side of the chair on each side. On the right I had placed a padlock in the eyelet and I fixed the end of the chain to it. I pumped the butt plug up a few more times until it was verging on uncomfortable and then put the plug vibrator on full. I then turned the dial on the magic wand and it began to vibrate immediately. I left it at about half power before maneuvering the clip on the left cuff into the eye bolt. I was now stuck.My release mechanism was two fold. The main release was a key tied by a long chord to the right eye bolt. The key would only release once some ice in a stocking melted, allowing the key ring to pass over the ice. The back up was also a key on a chord but this time I had cut the top off a two litre plastic bottle and cut a slot in the top where I slotted the chord. The bottle was filled with treacle and placed above a pile of my favorite (and expensive) work ties. If I really had to get out I could use this key, at the expense of ruining my ties.The plan was to milk my cock with the vibrator over number of hours. The vibrator plugged into the mains and I had connected it via a timer like the ones you use when you go on holiday. I had set it to fifteen minute intervals on and off as I didn't want to numb my cock with constant vibrations. I expectd to cum quite soon and then have the rest of the fifteen minutes of torment as my sensitised cock was vibrated. Then I would have fifteen minutes to recover until it started all over again.When I turned the vibrator on I guessed that it was just in the middle of the 15 minute 'on' period. I should have waited until it switched to 'off' before I finalised my bondage but I was just so horny I fixed the ankle clip in place and say in for the ride.It didn't take long for me to cum. Then I was stuck and I tried to get free as the sensations became too much. I composed myself and took some deep breaths and told myself I would probably have ten minutes at most until I could relax.Ten minutes passed (I was counting) and the vibrations carried on. Maybe I was a few minutes out. Only a few more at most. I counted five more minutes an then started panicking. It didn't take me long figure out that I must have forgotten to flip the switch on the timer from on all the time to 'timed'.The vibrator wasn't going to stop until I got free! At this revelation I lost it a bit and started struggling hard. I was cursing my handiwork at building such a solid frame. I considered using the back up release but I didn't want to destroy hundreds of pounds of my favorite ties.I will admit that this was also turning me on a fair bit though. I was getting totally done over against my will (kind of). My cock was hardening again and it wasn't long until I felt the next orgasm rising. I surprised myself with the volume of my groan through my gag when I came. I also surprised myself by the sounds I made afterwards as my cock was mercilessly stimulated in its super sensitive state. I was straining at every bond, my heeled feet flailing around. I was trying to get the clip on the left cuff free but I had been clever and positioned the eyelet so that the tension on the clip prevented me even getting close to releasing it.I started freaking out a bit after the third orgasm. I was pulling on the release key chord in the hope that the pressure would melt the ice quicker but i was terrified of breaking the chord.To cut a long story short I came nine times in almost three hours. I didn't know that was possible!When the key came free I was frantic. My hands were shaking so much as I pulled the key towards me. I was fumbling it trying to get it into the lock but must have spent about five minutes until I finally felt the key locate in the lock and that fantastic click of the opening.I couldn't turn the vibrator off fast enough. Next I took my gag off and just sat there breathing for a moment, collecting myself even before unclipping my left wrist.I turned off the butt plug and as soon as I deflated it it just dropped out of my arse, it had been stretched so much.I spent about twenty minutes undoing the other straps and getting out I the chair.Takin the heels off was incredible. My feet were seriously aching. I love wearing heels but that was the longest I had been in such extreme heels.I downed two bottles of lucozade and then ran a bath and spent an amazing hour undressing from my layers of latex in the warm water.That was a hell of an experience. You know what, I'm actually keen to do it again sometime!
