What an interesting game
Bearing in mind your interests, how about this:
Check out Boundanna.com to lean how to tie yourself to your bed, spreadegale, with a self release mechanism after a long period of time, eg 3 hours.
Set up a tv/laptop playing random porn videos so you can see it from where you are to be bound.
Grab a powerful vibe and get hard.
Grab a condom and fill with chilli sauce or deep heat cream and put it on.
Tape the vibe to your warming cock then tie yourself up as devised.
You'll be stuck there until you cum but unable to stop the continuing stimulation on your most sensitive area until you either cum again or the realse mechanism allows your escape.
(An improvement, but impractical one, is to use a mains based vibe such as a Hitachi Magic wand which is switched on but plugged into one of those timers that can be programmed to turn on and off the device. I set it to run for a few minutes on and a few minutes off. Sometimes I cum and feel the unbearable pleasure of post-stimulation, and sometimes it cuts off just as you edge, leaving you gasping for more...)
