They have also some SE traffic.
Some google searches:
short skirt galleries (short-skirts.org)
shemalecocktail (shemalecocktail.org)
shemale cocktail (shemalecocktail.org)
bbw thumbnails (bbw-big-beautiful-woman.com/bbw-porn,shes-huges,thumbnails.html )
old lady sex pics (old-women.info) etc...
It is not huge traffic yet but if You (example) setup unique auto blog with sponsor feeds + pinging + get some links then se traffic will be muuuch better. Most of them were registered in 2002 or 2003 so they only need some links to get really high in serps.
Some domains have nice designs (i think ) - sextip.net, sexoutlaws.com, sexzoom.net, sexmax.info, sexraj.com , 69arena.com, diablotgp.com, pornsat.com etc ... for some i have .psp so You can change design as You like.
