Daycare
World where vore is common and pretty casual.
With high birth rates and people constantly getting eaten, most places have lots of orphans running around.
Middle aged woman works as a ward at an orphanage, managing about a dozen kids at one time. She's an accomplished predator and her body reflects that.
Tall, strong, extremely stacked hourglass figure with a soft tummy that has processed hundreds of unfortunate victims into plush MILF fat.
She has a gentle side though and genuinely enjoys playing mommy for all the kids. But there's always troublemakers and punishments to be handed out.
She especially doesn't like when the predatory young girls try to snack on the other orphans. These disputes usually end with a satisfied belch from her lips.
The troublesome girls get a long time out in her belly and eventually take up permanent residence on her waistline. Not that she minds having them stick around as extra pudge.
She actually rather enjoys the idea that all the little ones are still with her and she's very open about it with the kids.
Sometimes she gets a bit greedy and eats kids for other reasons. It's just so easy to get carried away when you're playing hide and seek with such delicious morsels.
She usually lets the good kids out before they digest... but sometimes she forgets. She tries not to feel too bad about it though.
After all, gently melting away accompanied by her soothing rubs and reassuring words is much better treatment than most prey get.
