I mean, just logically.. common sense says at that point it would take a few seconds to confirm what was said and to be sure it was understood correctly. Probably the LAST thing you would expect to hear is "STOP"
Electronics have a response time measured in microseconds, not people.. be they male or female.
From the facts presented, it seems unjust.
Hell, even if you heard "STOP" during consensual sex, it could mean a lot more than "get off of me, you brute":
1. "Stop thrusting, I'm getting chafed, let's rest for a minute."
2. "You're pulling my hair, you oaf."
3. "I heard something strange, wait a sec so I can listen better."
4. "Wait, you're about to finish and I need more time."
5. Or, like the punchline to an old joke, it could mean "wrong hole, wrong hole!"
Etc., etc. The word "STOP" is often ambiguous itself, inviting the question, "um, stop *what*?"
Heck, I've heard my wife say "STOP" during sex, and she was telling the dog to stop bugging us.
