You are coming down with some symptoms and your step-mom thinks you have the virus that's going around. So she gives you the test and walks away. She comes back reading the pamphlet and says one of the side affects of the virus is shrinking. But she doesn't believe in that stuff and thinks you are hiding and playing a joke on her. But you aren't. You did actually shrink. You got smaller and smaller until you are not much bigger than a crumb. She sits down on the couch with her naked butt, and accidentally sits on you. She thinks you are a crumb that is irritating her ass. She keeps trying to get comfortable on the couch. She even lets out a few farts. And you are yelping for her to hear you. But she doesn't. You get blasted by her farts, covered by her ass. You even try to run. But you can't escape your step-Mom's huge ass. She tells her friend that she is just going to sit on the couch and wait for you. She gets comfortable right on top of you. Her asshole right on your little body. And it's pitch black. You can't see our hear anything anymore. And you are starting to lose consciousness...
