I used to enjoy self-bondage. I would have a nice hot deep bath, shave and powder myself, then get on the bed naked. I would fix a spreader bar to the clips already fixed to the foot of the bed, and fasten my ankles into the leather straps, pulling my legs wide apart. I would insert a wireless-remote controlled vibe deep into my open pussy, and I would put my hands into a noose with a slip-knot, the other end of the cord was fixed to the headboard. I had the control box for the vibe in one hand, so that I could vary the speed and pulses of the vibe.

My girlfriend, Elaine, had got the vibe for me to use when we went out, or sometimes in the house, with her holding the control box of course. It was beautiful, ten speeds, with eight different pulses from slow regular to fast variable. On full it was totally impossible to refrain from coming. If she knew I was using it on myself without her, I would be spanked so hard and so long, you could make toast on my backside.

By pulling gently on the noose, I caused it to tighten on my wrists, holding me fast, so that I could enjoy a few climaxes while savouring the feeling of helplessness. When I had enjoyed enough, usually two or three climaxes, all I needed to do was pull my wrists gently apart, and the knot would loosen, so that I could free my wrists, and unstrap myself.

Until this one particular night. 

All had gone smoothly, and I was twitching nicely after a couple of really great climaxes. I pulled my hands apart as usual.....and the bloody slip-knot stuck, and would not loosen. All I needed to do was turn off the vibe with the remote, and work the knot loose slowly, and carefully. Unfortunately, like an idiot, I yanked at the damn thing, and the remote flew out of my hand across the bed, leaving the vibe on full speed, variable pulse, and no way to turn it off.

 Now, what you need to know about me, is that after I come, I get ultra-sensitive, so I come faster and stronger with each climax.
