"Well, um..."
You are blushing quite profusely as you stare down at her, your body shivering more and more as you turn over in your mind the idea of becoming her poop. It always did really appeal to you to become poop for a cute, sweet, hungry little girl like her. Especially one who would be delightfully playful and teasing about it!
So, with your face still beet red, you slowly squat down to her level. "Well, I'll make you a deal Georgina.."
She leans closer to you, her eyes getting wider with eager anticipation, excitement, and hope! It's so obvious how very eager she is to get to eat you up!
You can't help but moan a little at that, and chuckle, giving her a bigger smile. "If you promise to keep me around for a bit longer, until lunch time tomorrow at least. And, if you especially promise that, in the time between now and then, that you will keep talking with me and teasing me about how I am going to become your wonderful, beautiful, perfect poop..." You blush even more, shivering as you decide you might as well go all in. "And, maybe, if you feel like it... You could let me be with you when you have to take another poop, to see what is going to happen to me. To see what you will turn me into. And, to let you show me how you will treat me after you are all done using me up..."

You tremble, feeling a very huge, hard, throbbing bulge in the front of your pants as you stare eagerly down at her. Just waiting for her response to your sudden eagerness and willingness to not only become her food and poop, but to have her tease and taunt you about it before she eats you!
