when i was in high school, i downloaded a bunch of "sex party" pics. about half way through, i realized that two of the girls both went to my HS and were in my year (though we had no classes together, because they were basically a step up from special ed, and i was....well, at least a little smarter). some of the pictures of them eating each other out and fingering each other were simply amazingly hot. they were close friends, but each had a bf and they never acted "lovey" toward each other (not in public, that is). after that, i could never look at either of them without seeing the faces she made while the other was licking her pussy.
honestly, though, it made me feel kind of dirty....haha.
