My gf has a hot belly

My gf is a little chubby and i love her belly. I like to rub it and tickle it, but I don't know if that's ok. I don't wanna hurt her and I don't wanna do anything that she isn't comfortable with. What do you think, fellow chubby lovers?<br><br>Edit: my gf is very happy to hear that this is done by other people and I would like to thank you all for sharing.
