Most times scrolling through adultwork or adultfolio the ladies who call themselves bbw are just fat with a gross dinner lady type of body.
BBW to me is beautiful curves and huge ass. Ava Rose when she was at her chubbiest or Mazzaratie Monica.
Very hard to find equivalent in the UK from what I have seen so far.
Alexxa Vice is a great shape to her ass. I do like em even bigger though if they have the shape.
I do not mind milfs at all as long as they have the shape! I would say body shape is more important than age (within reason) and face!
There was a nice milf bbw someone posted here some months ago who had an adultfolio profile but I forgot her name now and didn't save it at the time and can't find the thread any more.
