Your step-sister found your in her room again, but this time sh'es not telling step-mom and step-dad, she's taking matters into her own hands. She's super sweaty from her long workout so she calls you into her room and makes you bury your face in her ass! She tells you to take a big whiff and don't complain, or she's telling step-mom and step-dad what you did! After you with her stinky sweaty ass she makes you lick it and stick your tongue in it, calling you a loser for letting her do this.
