It's called adolescence. It's simple psychology. It's supposed to happen.
Also. This N has a little sister. One really hot, lazy, mean bitch of a little sister. Well, she's got her good days too, but most times she's just either lazing out by the TV or playing the rampant teenage girl part.
This N is mindfucked to eternity and back, but not that way. IRL siscon is just, no. I'll leave that to the copypasta-writers of /b/, thank you very much.
