I definitely use it when I'm craving something mega-intense and want to challenge myself (not often, I've had the blade fall on my cock maybe 5-10 times).
I've done it in self-bondage with cuffs and carabiners (which take at least a few seconds to release, much too long to get out once the shock begins). The anticipation of watching the blade rising and trying to prepare for the hit is such a mindfuck. I've also played while wearing a hood, and it's almost a different when I can't see the screen and can only guess when the shock might come based upon a rough estimate of the settings.
I still have a bit of room to go with it too. The one time I actually turned my ET-312 to high power at 100 and ran it, I had been warming up with other estim play and did the guillotine once before at around 70. Someday I'm gonna do it with no electro warmup at 100... I've also considered taking it to a kink party and use the venue's very appropriate bondage furniture to setup a little demo and see if anybody wants to volunteer...
The last time I did it, I wanted to see what it would be like to have the blade fall as I came. I started it and didn't bind myself up right away, edging to right before the point of no return until just a few seconds before the blade was going to drop. I quickly put my hands behind my back and clicked the carabiners together and braced feeling like I was about to explode... But then the blade malfunctioned and one tiny spurt of cum dribbled out. The blade went back up, so I released the carabiners and started edging again (though still a bit stunned from the anticipation the last time), and this time as the blade got to the top, I went just a bit further to the point that I was fighting hard to hold back the cum as I bound my hands again. This time the blade fell and I immediately came in obliterating agony. It also occurred to me afterwards that I have only ever done it using a bipolar loop on my cock, but if I had instead wired it up between a loop on my dick and a plug inside my ass, I might have been literally unable to shoot anything because everything would be so contracted, perhaps next time haha...
Also ptdw
PLEASE keep making scripts!!!
Your scripts are really unique in that they don't try to excessively anthropomorphize themselves. (While I know this is just personal preference), scripts that try to suggest something human(oid) is involved fall so short for me that I can't get into it. (It probably also doesn't help that I'm gay given the script pool here). Also being controlled by technology itself is a somewhat distinct fetish that I identify with much more strongly than the simulated-human kink.
You find really creative ways to navigate the platform's limitations. I like that you distance the human characters and put the focus on a strong game structure that can be played in a reasonably short amount of time. I think keeps your scripts interesting and gives them a lot of replay value. I'd love to see what other fun games you could come up with. One possibility could be a JOI game (along the lines of edgemeplease.com - I can't post a link in my first post haha). While simple in concept, it could offer so many possibilities for twists along the way and variations on an ending that I think it could be really fun. Of course more estim games/punishments would be amazing too.
