Other profiles that I suggest on spankbang are:
Fleetwood
chubbychaserx
thegokussgss and TheGokuSSGSS_pt2
Zxc123456789000 (sometimes posts BBWs)
For the downloads:
first thing you need is having Adblock (or even better uBlock Origin) on your browsers because the websites I'm suggesting are full of ads.
The main professional BBW porn websites nowadays are: XLGirls, Plumperpass, Jeff's Models, RodneyMoore and Pure-BBW.
The main websites that leak stuff from them (usually in HD or full HD) are:
on megabusty you'll find a lot of scoreland / XLGirls / Plumperpass stuff.
on 720porn you can find pretty much anything BBW, so the above + Jeffsmodels + Rodneymoore + stuff like JacquieEtMichel, DesperateAmateurs or Mature.NL if you're into them.
asexon.com shares almost the same database as 720porn (almost).
werelovemeat is the only one I found that has a lot of Pure-BBW porn that is very rare to find anywhere else (except on megabusty, sometimes) plus some RodneyMoore vids.
naughtyblog leaks mostly score/XLGirls stuff and Plumperpass but you can also find stuff from other BBW websites. Unlike the others, tho, it is not updated regularly and too old videos may have been removed.
A reminder that on some websites you can also search for "plumperpass" or "jeffsmodels" or "xlgirls" etc. to filter results (especially on 720porn ).
If you still do not find what you're looking for you should Google it this way
"Monica Mazzaratie" "Game Time" download
with quotes included. Then you need to switch to Google Images, mouse over the images and open the pages for the images that are thumbnails of the video (skip all the other crap). Some might be torrent websites such as rarbg, skip them. You'll get on websites such as boobsjuggs.net, forumophilia, 0xxx.ws, pornoh.info, newpornoreleases, k2sporn, planetsuzy, porn2d.net and many many more. If the video is old the links might be dead but if you look for it enough there's a possibility that you find it.
Now the problem is that you need to download with premium speed. To do that you need two types of links: rapidgator and uploaded.
Megabusty is useful because uses rapidgator almost all the time (even though lately it's not using that but this has happened before and my bet is that in a week or month they will use rapidgator again). Rapidgator links are also used on 720porn (but are slowly disappearing) and on asexon.com, but this one usually has uploaded links while the first does not.
Werelovemeat uses uploaded links.
Naughtyblog makes use of both rapidgator and uploaded among with others unless the video is old.
To download as premium you need to paste the rapidgator or uploaded link either on leech-brasil.com or cocoleech.com.
You need to register on leech-brasil (it's easy, doesn't require mail if i remember correctly) by clicking on "Cadastre se" (or going to leech-brasil.com/Registro/ ).
To login insert the username in the name field, click login and insert your password.
Now check the box "Auto check link" and paste the rapidgator or uploaded link, then wait for the bot to give you the link in the chat.
Click on that link and be prepared to skip 4-5 ads and then there will be your download at premium speed. A couple websites might ask you to disable adblock so do that (it's annoying but it's the only way).
Leech-brasil has some limits, I believe 600 MB for rapidgator and 1GB for uploaded so be aware of that.
For rapidgator links >600 MB you can use cocoleech, just paste the link and skip the usual crap. Cocoleech is however sometimes unavailable (could tell you that they have no more daily traffic after you skip all the ads).
If you know better ways to download as premium (and possibly from other websites like keep2share ) please let me know.
PS: don't forget that the videos usually leak on torrent the same day they get released or the day after.
