Kicking and screaming all the way down, Bryan was helpless in the torrent of foamy beer washing him into his big brother's gullet. He kicked, and punched and screamed as the putrid smell of beer and stomach acid choked him. It was dark, and suddenly turbulent. Don must have gotten up, and was walking. The sloshing of the beer had drowned out the words Don had spoken, but Bryan could hear the distorted music from the bar getting softer, as Don walked down the hall to the men's room.
Don had scowled at the bartender, but as he walked down the hall where no one could see his face, he rubbed his belly he grinned. Inside his stomach, Bryan was treading beer in an acid bath. Don was already feeling the effects of his chugged beers, as he staggered into the stall, and dropped trou. He sat right on the cold wooden seat, and sighed in relief as his bladder and bowels emptied themselves. An unexpected belch reminded him that he'd just swallowed his little brother, or a tiny bug that looked like him. Don knew he should feel bad about it, and he had before he swallowed, but now he felt omnipotent, like a god. He wondered if the barkeep had any other little guys that he could swallow whole.
Inside his stomach, Bryan heard the rush of piss like a fire hydrant left open in the hot summer, followed by the loud shit leaving his brother's giant body. He didn't hear the belch because he was submerged as the gas bubble he was breathing vanished, and emerged as Don's belch. Bryan was drowning now, as the stomach churned and pumped more acid to dilute the beer and dissolve Bryan.
