Good afternoon everyone. It's a bit of an odd question, I know, but let me explain. A while back, I saw a kinky Peril video where our heroine was bound and hooked up to a machine that would stimulate her but would automatically shut off right before she climaxed. The context of the scene was that our antagonist was trying to mentally shatter our heroine, so the machine edged her like this for hours and hours. Obviously, we all know that porn is a fantasy, and portrays an unrealistic form of heightened reality, but I'm curious if there is any semblance of truth in this. Would it be possible for a machine reading someone's vitals to recognize when they are climaxing, and if so, could it also recognize the moment right before?
