You feel a lurch in your stomach as your grandmother shifts and settles in. Soon your belly is rocking rhythmically and the sound of muffled moans can be heard. Your grandfather lets out a booming laugh.
"Ho ho! I always knew she'd like it once she get into somebody's guts."
You look to your grandfather, but belch before you can form a proper question. He seems to know what you were going to ask.
"Been trying to get her to agree to get eaten for years, she knows me well enough that I couldn't catch her off guard. I told her she'd love it if she ever did get gobbled up. You can always tell a good gutslut." He gives his belly a slap. "Just like your sister here. Give a listen boy, she's enjoying it too."
You move to put your ear against your grandfather's squirming stomach.
