i would appreciate to see in this discussion pictures of pornstars with breast implant scars
/Points at literally any huge tits website, e.g. Scoreland
Although Score airbrushes/edits the hell out of their sets, often.. (or did they stop that in recent times?)
You could also look up 'implant scars' on reddit.
You wont actually find many pics, but Reddit is chock full of whining (sometimes valid, sometimes not) about everything, ever. So if you read about this pornstar or that O.F. model having scars, well.. there's yer sign to go hunting for such things!
Other than that, try the imagehosting websites and search for 'bolt on', 'botched', 'scars', etc.
