Im Step-Brother's Fart Seat while he is Gaming

Description: My step-brother's farts are toxically dangerous but i love to smell them too close, and now he is gaming after lunch and i propose myself to stole any stinky fart of his sweaty asshole. so, i will propose him kissing his ass and buthole out of smelly boxers. when he is relax i will take off her boxers to smell his flatulences better. i will take advantage of lick and kiss his butt and balls because he is the best step-brother in the wide world and i will make he feels like an alpha male because he is one.
