I'm not sure if I'm entirely understanding the question right - but if you get caught right now it should end the night almost instantly.
Ah! I think I understand what you mean.
If you get caught, it will end the night as soon as the eyes opening animation is finished. Basically you have until then to finish any other animations on the screen.
I'll look into seeing if I can add a delay if you're climaxing, however. Seems a bit unfair to do all that work and not at least get the payoff, even if it is still technically a game over.
