Perhaps the best collection I've come across till now in terms of picture quality.

How many chicks rode in the buff? Can't tell for sure but that turnout was amazingly encouraging, with a well-balanced mix of everything! Which lady would I want to see again? Well, there's one in the Borat suit, one in pink stockings (she went for a full frontal yellow-green body paint, but still with a very cute face), one Philippina (should be), THAT nude babe doing her acrobatics with a hoop, one topless chick on roller blades, and a lot more.
Let the other sets roll out in the hours to come. As far as toplessness goes, I wouldn't complain
