You and your giantess step sister kira are watching TV together. She doesn't really want to bother watching you so she tells you to just hang out on her shoulder. Suddenly you slip and fall onto the small of her back and slid into her butt Crack. She doesn't notice you at first and you have to endure her farts and her trying to deal with an itch in her ass. When she does figure out it's you between her ass cheeks she simply plays dumb and begins to tease you with feigned attempts to find you. She gives you the ultimatum to come out or at least say something, otherwise she will punish you for being somewhere you shouldn't. After several warnings and ignoring all your attempts to be noticed she tells you if she finds you now that she will replace the back of your other step sisters thong with your naked body. She then reaches back and pulls you out of her ass before securing your hands and legs to her sisters thong. She puts you away and you are stuck in her drawer until your other step sisters comes home. She comes in and undresses before slipping the thong on without noticing you. She then unleashes fart after fart on you before her step-sister calls her and let's her know that you threw away her lucky thong.

Then she shows no mercy as she decides to keep you there and make you her new lucky thong.
