You've always been such a major pain in my ass, little StepBro ... but maybe you would be less of a problem if I made you my TINY stepbrother instead! It's bad enough that all you do is jerk off and play video games, but now that you ate *my* leftovers (you should know better to do that with a chubby girl like me!) it's time for me to PUNISH you! I decide to try this funky spellbook I found at a booksale (you DO know what a book is, don't you?) and it turns out the Shrinking Spell is legit! Seeing you so itty bitty gives me such a thrill, finally allowing me to torment you like you've been doing to me for years -- only, I am a HUNDRED times bigger than you, leaving you absolutely helpless to my every whim! I tease you with my dirty feet (is this why they call me a STEPsister?) and threaten to crush you under my fat ass, not giving a damn about your lungs when I rip a huge fart on you too (do you still think farts are funny now, twerp?). Don't try and hide now, you were always peeping on me changing or in the shower, are you really going to pass up me offering you to gaze freely at how massive my tits look compared to you? What are you, afraid of being squished like the bug you are beneath them?? All this power gets me really turned on, so I decide to pull out my hard, bus-sized girl-cock and steal some of your sad jerk-off lotion next to your gaming chair to start stroking myself right above your head. Go ahead and gaze up at your big, BIG stepsister as I slide my fingers across my greased-up shaft, you're helpless to do anything else except join me in masturbating as I tell you how tiny and pathetic you are. Finally I reach my climax and unleash a deluge of sticky, sweet tgirl cum all over your entire bug-sized body! There, that should teach you a lesson! Now that I have had my fun, I suppose I can turn you back to normal size -- only to find out, there is no reversal spell! Oh crud, I'm going to get in sooo much trouble over this... unless... no one was to find any evidence. I mean, your puny remains would be SO easy to hide, and well, you *did* eat my leftovers and leave me starving! So when you think about it, it's really all your own fault that your step-sister is about to EAT you! If you wanted one last orgasm before your demise, better start stroking fast before you reach my very hungry and start getting digested alive along with all my cum! By this time tomorrow, I'll be flushing whatever is left of you away and pretending to be soooo sad over the mysterious disappearance of my worthless, stupid little stepbrother!
