She smiles at you, "I have the perfect place in mind, it's snug, warm, everything you could want it to be!" She chuckles a little evilly, "But it does have a unique aroma to it, I am sure you won't mind though!" She starts to slowly slide her tail back between her legs, you look up and watch as her large belly slowly blots out the sun. You shudder as you think of how many living things it took to give her a large belly like that, and are very happy you won't be adding to it, for now at least. After a few seconds you realize you have stopped, under the base of her tail. You get a feeling of dread as you realize where she is going to be holding you.
Her tight tailhole is much larger than you, obviously, and has many small stains on the fur around it. She bends over and starts to slowly slide you towards it. By bending over she lets you see her tailhole better since the sun is now shining on it, but it would have been best if it hadn't. You can see just how filthy it is, she obviously doesn't clean herself too well. You suddenly see it flex a bit, and the next thing you know she is releasing a large, noxious fart onto you. You gag on it for a few seconds, before you are finally pushed against her. You struggle aginst her tailhole and tail hard as she slowly slides you in, moaning in pleasure at your futile struggles. You can feel her tailhole flex powerfully against you, and worry that the powerful ring of muscle may crush you. However it doesn't, though that isn't entirely a good thing. The stench in here is awful, you almost toss your cookies at the horribly powerful smell. You can feel her bowels massage at you, giving you a vile massage. You are very thankful that you can't see in here, it is likely even filthier than her tailhole. You struggle against her anus for a while, trying to get out, but she has flexed it powerfully so that it is too tight for you to slide out. You finally sit down after wearing yourself out, you know that you don't want to go farther into her, that would be a very bad idea. You can only hope that you can get out before you aren't the only resident of her rectum.
