Well, it seems you got her to stop. You also seem to have hit a nerve, or struck a chord with her. It's hard to tell. Now that you've gotten over your initial shyness, a more predatory confidence wells up within you. You decide to have a little fun, so you push things a little further. With a grin, you open your jaws nice and wide to yawn-like state. You then relax your throat and lull your tongue out while your lips curl into a wide smile.
“Try me...” you say, making Doki go deep red in the face as she shows obvious fluster to your actions. It seems less like she has you cornered and more that you are starting to corner her. Maybe you just might make it out of here alive—maybe even with a nicely filled belly as well!
Doki's grip gets a little weaker, her words now just nervous stammering as her eyes shift between your face and belly. As she's busy contemplating the consequences of her actions leading to this point, she's distracted enough that you can take advantage of the situation.
