She starts letting you out. Your head pops though her mouth and she realises you weight no more then when you entered her gut, but she assumes you ate Lyra. It's not what she wanted, but a promise is a promise. She keeps letting you out and, when your belly exits her mouth, with only the little layer of fat you've always had, she discovers your plan and, with a powerful gulp, sends you back to her stomach. "You tried to trick me huh, well I told you that if you caused troubles, you'd be digested so..."
And that's what she does, she driftes to sleep and her stomach starts digesting you. You could fuck Lyra, but your dick won't get hard in a while. And with that, your lives end in a slow and painful digestion process and add to Peyton's body.
The next morning, she has gained all the things you could give her. She now weighs 330 pounds. Her breasts are now a L cup. Her hips are now child birthing hips, her ass is like two soccer balls and her thighs are thick like logs. Like vengeance, you also added to her belly, making her pudgy midsection grow like a nine month pregnant belly. "Oh you had to add your bodies to my gut too. It looks enormous for a person of my size."
