I love any theme that involves super hot topless women. The theme could be 'Chicks Who Dig Tree Frogs' or 'Women Scared of Model Trains', I care not, so long as the list includes a bevy of sensational looking women with even more sensational funbags.
Of course, our friends across the pond at Nuts magazine get more to the point with their themes, is in the case of their outstanding current pictorial entitled 'Big Boobed Brunettes', which features among the winners the uber-sextastic Lucy Pinder and the amazing Holly Peers; they both certainly more than qualify for the category.
Yes, we love a good theme, especially one that requires very little thinking and lots of ogling. Enjoy.
