My loser lil step-bro is in trouble! My boyfriend complained that my ass wasn't clean enough, and that's clearly his fault because it's his job to make sure my asshole is clean before my boyfriend fucks me. I'm the bigger, stronger step-sister and he has to do whatever I tell him. This time I am making him spread my cheeks wide and examine my asshole closely, making sure every bit of sweat and grime is cleaned up. I don't want a single drop of it left behind. I also have lots of farts to push out before I go see my boyfriend, so my nerdy step-bro has to inhale all of those too. I fart right doown his throat while his tongue is in my ass. I describe how he will have to clean up after I get home too. He is sad because he wanted to play games with his online friends, but he is no longer allowed because he has more pressing duties like sniffing my farts and cleaning ass. He really will be a loser virgin forever.
