Pastel Goddess - Mean Step-Sis Bullies Her Wimpy Step-Bro

-custom- my step-parents have gone away for the weekend, so i have the whole place to myself! or rather, i would, if not for my annoying little step-bro constantly nagging me to help him with the chores. he's so annoying! i'm in charge around here, so why should i have to do anything? i knee him in the balls when he complains and he falls to the floor crying. i take his wallet containing all the allowance money our step-parents left us. it's all mine now! i explain to the wimp that i'm having a party tonight, so i need him to clean everything. he protests that i should help, so i strip him down and then handcuff him behind his back, then begin to lay into him with kicks and knees to the balls. he has a low pain threshold, so he is constantly flinching away and trying to avoid the pain, but i pull him close and knee him hard. the ball-busting is very intense for such a weak boy. it goes on for several minutes without any rest. when i feel i've gotten the point across, i tell him to get to work cleaning. cut to a few hours later, the party is about to start so i chain him up underneath my bed so he doesn't bother any of my guests. the next morning, he is still there, begging me to let him out. i take him out because he needs to clean up the mess that me and my friends made, but not before he kisses my ass, tells me i'm the best step-sister ever, and gets ballbusted again! in the final minute i break him down to tears. he feels so humiliated and pathetic, and it's because i'm the boss! i leave him there to get back to work.
