well there unfortunately isn't any easy way to search group galleries so other then just looking back through old gallery pages I can't suggest any easy way to find specific lines. however since we get quite a few submissions here everyday then chances are what you want will pop up eventually ^^

so to tide you over until then i managed to find some lines that hopefully fit your criteria.

catgirls - [link] [link] [link]
couples - [link] [link]

hope this helped and good luck with your search ^^

there's one, not sure it's what you want though... If this doesn't work, check fantasy

Thanks! It has been corrected
