Hahaha, fuck man, I like these pictures! Makes me think of the League Of Gentlemen right away!
It's certainly fucked up to go fuck your sister in public, but sometimes I wonder whether incest if between to consenting mature individuals is really so bad? I mean, as long as no children get born out of, of course. It's perverted yes, but say a brother and sister are humping each other in private, using anticonception, is it then really worse than any other perversion?
(I still would think of them as freaks though, hehe...)
