When You say HQ (high quality) how high are you wanting.
If you double click on any photo in the 'Girls caught Peeing' or 'No toilet necessary' threads you will see it fullsize and in better quality. How HQ is open to deffinition and individual photos.
If, as I imagine your not looking for candid shots but more explicit photos,well your in the wrong place try the hardcore section of the forum or look for a specialist site.
Sorry can't help more,its not really my thing.
