Incest

Someone on /b/ keeps claiming that we have genes that prevent us from being attacted to our siblings. How true is this? I for example find my sister extremely hot. I masturbate to her pictures all the time and would fuck her without a though given the chance.

actually, in truth, we're very much in love. it doesn't feel weird since we were apart for the important parts of our lives. also, since we're of middle eastern decent, its not really viewed as weird by anyone else (not that they know, but still).

she's really hot, but we aint done nothing, well except hugging.

okay, just for you anon, i gave her a blowjob :D
