Step-brother turned fart slave

Being all alone at home with my dorky, nerdy step-brother is anything but fun! He's so fucking boring and gets more annoying as time goes by and since we're all by ourselves, I figured... Why not make him more useful to me? He could be of use to his older step-sis, couldn't he? For example, by dealing with my nasty farts since I'm so gasy at the moment... And he could also come in handy when it comes to dealing with these stinky, dirty socks full of holes! I'm gonna make him buy me a new pair but not before he sniffs and licks these ones, for sure! Haha what a loser!
