I have a ssbbw friend I've known since high school. I was with her at her place last year and noticed she wasn't wearing underwear. Her belly hangs so low that you wouldn't know she wasn't wearing any.
Is it that the ssbbw belly needs to hang low enough to allow her to hide the fact she's not wearing underwear or she needs to reach at least a certain weight to pull that off..so to speak?
My wife's gotten to the point from some angles I have to spread her fat rolls apart to even find the fabric.
She told me she's been wearing the same undies since high school! I asked how that's even possible considering she's at least doubled in size. She said her body's so soft the lingerie just comfortably sinks deeper and deeper into her fat!
