I love doing this! I like to do this whenever I can, and have also done this with my girlfriend before, when we've had our little playtime!
If I'm in little mode, I'll like to eat messy stuff with my fingers, like fries or nuggets for example. If I'm just wearing for comfort, I can happily sit down and eat a roast meal with a knife and fork, and just slowly leak and dribble into my nappy as I eat.
It's also fun to do without a nappy in as well. I'll pretend that I'm not allowed to leave the table until I'm finished, but I don't want to eat anymore. I'm forced to sit there, and I'll wet my pants at the table. I only do this at my outside table, because it does make a mess.
Eating a melting ice cream in my little mode is a lot of fun as well. I let it melt and start to drip, and I really need to pee, but I can't put my ice cream down, so I will be potty dancing around with my ice cream dripping everywhere, making a big mess while I try to finish it before I go inside to use the toilet.
Alas I don't always make it......
But to wet my pants while eating an ice cream is something that really gets me into little mode. Of course I might be diapered afterwards as well!
