"Hmmmm... I should probably work off everything I ate last night, and whatever I'll have for breakfast too," Monica said to herself as she walked over to a pile of dirty clothes. "I'll just no reason to dirty up any new clothes," she said as she quickly put on the thong that was your prison. You watched helplessly as you were rushed between her towering legs, into the mountainous cavern that was her asscrack and finally stopped within arms reach of her huge asshole. The anus was twice your size, you could see every bump and wrinkle, it was covered in a layer of slimy grease and the smell was ten times stronger now that you were up close to the disgusting sphincter.

         Just when you thought it couldn't get any worse, Monica bent over. Her mountain sized asscheecks spread apart, her sphincter opened and her thong was pulled tightly against her skin. Your face. Was now pressed against the top of the opening of her anus, your arms, chest and waist were in the opening and your legs were pressed against the bottom. The smell was now hitting you full blast, Her asshole felt much more grimy, sticky and oily than it looked. "Where did my shorts go? I know there in here somewhere," Monica said to herself as she continued to look with her ass swaying in the air. Suddenly a strong silent and constant gust of wind came rushing through her open anus. The long silent fart rushed into your lungs as you breathed, it smelled even worse than what you were already being exposed to and felt like hot steam from a sauna. "Here's a good shirt, but where the hell are my workout shorts," she said as her ass continued to release the seemingly endless silent but deadly fart. You were starting to wonder if Monica would ever run out of gas, this single fart had been going on for nearly ten seconds now. "Here they are," Monica said as her fart finally ended and she stood back up.

          Her thong separated from your back leaving you plastered to her asshole as it closed. You were able to turn your head to the side just in time to see a wall of bright pink consume and squeeze her ass. Her shorts were so tight that her two large ass cheeks were struggling to find room, they were slammed together and were pressing you against her anus. Monica's asshole opened and let out another thunderous boom, your legs were swallowed up by the sphincter before it closed. Everything from your stomach down was now her buttplug, your arms, chest and legs were pressed against her anus and the air was completely replaced by her last fart.

          You felt Monica's asscheecks rub together as she began to walk. With each step you were pushed against the oily skin of her asshole, you tried to pull yourself out between each step and it was just enough to stop you from going any deeper. You heard a door shut before Monica began to pick up the pace. The asscheecks pressed against you with more force and the time between steps shortened, you tried to keep pulling yourself out but it was too much. You were being pummeled into her sphincter. She only took five steps, now only your hand was sticking out. Then Monica let out a loud and powerful fart, you were flung out of her anus and against her asscheecks. The second she finished it started all over again.

         Every time she took a step her butthole consumed a little more of you, once you were devoured completely it held on to you for a while before spitting you out with a release of ass gas. After the third time you were covered in the same oily slime that coated her anus. After the 20th time you began to notice that she was beginning to sweat. After the 50th her ass and you were completely covered in sweat, spreading up the process. You were forced deeper into her anal canal as you waited for her farts, only to be quickly pushed back in after you escaped.

         You had long sense lost track of how many times we were spat out of her sphincter, but you noticed that the smell wasn't as bad. It wasn't good but it wasn't nearly as bad as it was earlier, but that couldn't be possible with the amount of sweat and gas that this city sized ass was making. So that meant that you must be getting used to it. Frightened by the idea of becoming accustomed with Monica's foul farts you began to do everything you possibly could to escape, but nothing of worked. Then Monica began to slow down, you heard a door open and close before she came to a stop with you inside of her anus. "Wow, I really worked up a sweat" Monica said to herself.
