The snake paused for a moment, scarcely believing that she really went unconscious that quickly.  He'd expected more from her.   He immediately relaxed his grip to make sure his embrace didn't prove lethal.  He wasn't finished with her by any means.   In a few minutes she'd awaken, and he'd do it again. And again.  And again.   Eventually, she'd either submit to the hypnosis or willingly lead him to her calves just to end the delicious agony.  Plus he hadn't fucked her yet, and he wanted to make sure she was fully conscious for that.  The she'd be going a completely different kind of screaming.  So he waited patiently for her to come to, having now gotten a taste of what he had in store for her.
