Munchies:
Here's a fun fact. Your lower stomach - specifically the space between your navel and your mons - is an erogenous zone. Try teasing and massaging that area on a stuffed belly. It'll feel amazing.
Wait what does everyone have that? I thought it was just me XD
Edit: oh and to respond to the original prompt, it's practically impossible for me to pleasure myself without cradling my small (for now) overhang. Even before I started gaining that was something I liked but now it's almost compulsory for me lol
