3 over and 6 down will give you the set you seek, plus lots of other good ones.
Also saw some promising Andi and Ariel lez pics posted by Ponchdog (the webmaster for both sites), awhile back but a full set never has emerged.
Apparently the pics move around when you leave the site I posted. Just look for the pic of her in the furry red and white outfit.
