As in bumping bellies together or like, bumps/lumbs from prey being inside?
Bumping bellies is very hot, as is anything that makes bellies slosh and jiggle.
Bumps/lumbs from prey are good, though I'm not as fond of very detailed ones. Huge fan of animations of prey struggling bouncing the belly around.

I'm in full control of what happens in my gut, so really I could keep someone in there indefinitely! Nothing funnier than inconveniencing a friend by keeping them in there for a few hours as I go about my day.

Thank you kindly! You really can't go wrong with cheeseburgers and fries, with pizza being a close second. If I'm in the mood for something sweeter then it's dozens of donuts or gallons of melted chocolate.
