Lexi gathers a big spoonful with you in it. You try to spill out over the edge, but aren't fast enough.
"Have fun, haha." Lexi says, her milky cereal breath washing over you. Lexi shoves the spoon into her mouth, and pulls it out clean from under you. You are swished around in the great big mouthful of milk and cereal, luckily (I guess you could say) not chewed up. Lexi swallows happily, sending you into her stomach.
"Ahh...now that tasted gooood." Lexi pulls up her shirt and pats her bare belly.
You fall with the river of milk and mushed-up cereal into a lake of the stuff. Lexi's stomach welcomes you with a deafening growl. You get your footing on top of a big flake she missed while chewing, and steady yourself as a big wave of more milk and cereal mush is swallowed and enters.
"This is it," You think. You are going to die in here, no doubt.
Lexi slurps up the rest of the bowl by drinking straight from it. She spills some milk on herself, and it dribbles down from her shirt and onto her slightly bloated full belly. Lexi licks up the milk around her mouth.
"Yep, that was awesome." Lexi rubs her tummy, cleaning the milk off. It rumbles and blorps with the sounds of digestion.
A big shake and you fall from your raft, into the milk and acid ocean. The milk keeps the acid from burning you too much, but you can still feel it. Quickly, you try to find another raft, but unfortunately, they've all been broken up by Lexi's chewing. Her stomach is filled with a humid air, carrying the stench of milk, sweet cereal, and stomach acid. You can barely breathe.
Outside, Lexi feels a strange pressure build up in her. She makes a weird face, and burps really loud. All that air had to come out somehow. Lexi giggles, knowing that you heard that and were a part of that.
Lexi walks back to her room, her shirt still pulled up so she can see her tummy's slight movements as you digest. She lays down, and it shifts the entire cavern. Now, you're drowning in milk.
That shift makes Lexi let out a long, deep belch, as her stomach settles.
"Mmm, tastes like cereal." She comments, giggling again.
