Taking My Step-son to Work

You've always been a bit of a step-momma's boy, and even though you're all grown up, you still want to spend time with her always! Including when she has to go to work. You beg (implied) her to let you join her at the office, but how would it look for her to have her grown step-son joining her at work? Of course, you have a solution already: a magic app that will temporarily shrink you down! She's not entirely convinced the app will work until suddenly, you're shrinking before her very eyes. Once you're barely an inch tall, she picks you up and places you between her ass cheeks, right next to her hole. No complaining about the smell since this is your idea, she tells you. You don't even care, you're finally getting to live a fantasy you've had about her. That is until she farts, right on your tiny body. Oops! Too bad though, if you can't handle her gassy farts, you don't get to sneak into work with her, so you better man up and get used to the smell...
