Pervy Step-Bro's Eggy Ending

You know it's very wrong to have these sexual fantasies towards your Step-Sister, she would never let you do the things you've always wanted to do with her. So you come up with the genius idea to shrink yourself down so tiny she won't notice you perving on her in the shower. Wow you have the perfect view, this really is a dream come true and your tiny willy has even gone hard! But what you didn't realize was that being this small comes with risky consequences - especially when she steps on you and feels something crunching underneath her foot!
You think she will let this slide... but you obviously have absolutely no idea of what a vindictive piece of work your Step-Sister can be. She's especially moody when she's got gas, and you are going to pay for being a creepy little pervert. She starts farting on you in jeans, but when she notices your little boner it's time to remove the filter of the jeans so that her bare arse is burying you - her ginormous farts surrounding you, vibrating your entire body, the pungent stench filling your lungs with what can only be described as HELL. She thinks you've had it too easy, so she pops you deep inside of her ass hole. There's absolutely no escape for you little Step-Bro, all you can do is accept your miserable fate of inhaling and tasting her stinky farting arse hole.
But when your Step-Mom comes back from work early, she decides it's time to remove the evidence of you entirely. You are just not worth the risk of getting into trouble over. She pulverizes you with her ass. Sitting on you again and again until your pathetic existence is no more.
