Is my sister as hot as all my friends claim she is?
Apparently there is a /b/ archive and OP made a thread like this on 8 feb this year.
But for some reason the images are all 404'ing there and i can only see low res thumbnails.
I think your a creepy faggot who's sister looks at him with the mixture of revulsion and pity, and your autistic mind misinterprets that as her wanting to bang you, when all it is is her wondering "Would his life have been better if I had smothered him in the crib?". The answer is, of course, yes.
/b/, fucking up OP's relations since a long time ago
