What a little stinker !! Definitely a food response, if she tried to constrict. She tagged you pretty good, too, defensive nips hardly ever leave a mark.
Well, she got the heat signature and something must have suddenly smelled like prey to her. Who knows, something in a hair product or perfume ? Many perfumes contain (some natural, some synthetic) "musk" to give them a bit..uh...sexy/animalistic vibe? Some contain pheromones.
With their Jacobson organ or sense of smell, perhaps something just triggered her for a second, and that plus the heat your head gives off, BAM.
She still loves you![]()
