Julia took a break from pretending to study by putting her books down on the floor. Now she was actually watching the movie with Natalie, who had snuggled up against her. Julia didn't mind, Natalie had always been the touchy-feely type. The one who was being even more touchy-feely was Julia's anus just a few moments ago when it was latched around your head. This thought made Julia smirk to herself. Natalie had no idea, and anyone who could see them right now would just see two cute girls watching a movie, but deep within one of their butts was a tiny man struggling for his life against a mammoth anus.
Now that Julia was paying attention to the movie she could send you codewords that made more sense in context. There was a dramatic chase scene going on, the protagonist was pursuing the bad guy to his evil island lair via helicopter. She took note of this and asked Natalie "Do you think it'd be more stealthy if he used a MOTORBOAT?" After emphasizing that last word she gave her ass a little clench signifying to her tiny butt slave his next job. Natalie went on about how a motorboat would be hard to dock on the island because of reasons but Julia was more preoccupied in simply awaiting your response.
Motorboat her asshole? Oh God why... Straight in front of you the massive anal gate was sitting there, waiting. It was slick with pungent juices that reeked to high heaven. The slime dripped in a small puddle around your feet. Not wanting to be crushed by Julia's mighty cheeks again you spread both arms out, pressed on her greasy rim for support, and leaned in. As your face approached the shithole beads of sweat ran down your forehead. Julia's anus was hot, scorching hot even. Being this deep in her ass was like you had been trapped inside a steamy smelly sauna. The hole twitched and you realized you didn't have much time left. You took a deep breath and shoved your face into her anus.
The rubbery skin of the asshole sunk in. The glistening surface, wet with disgusting mucus, adhered to your face ensuring you'd be unable to breathe until the job was done. Nestling your head in the hole you smeared your face from left to right. Rubbing your bumpy face across the dirty crevices felt awful but it was working. The tight ass began to loosen allowing your head to continue deeper. Once more the farthole opened a little bit, giving access to its inner flesh. The pink pit was softer than the outer part of her butthole. The pillowy flesh sunk in to the mere touch of your face. It quivered and you thought this must be where her skin was more sensitive. Pressing you lips against the wet hot flesh you shook your head violently side to side and gave Julia the biggest motorboat you could muster. Julia gasped and jumped a little. Her asshole pulsated and throbbed around your head but you kept going. Her pleasure soared and the huge sphincter sucked on you like a popsicle, threatening to pull you inside.
Natalie got off Julia and asked if she was okay. Her jolt of pleasure shocked Natalie out of her snuggles and left her a bit concerned. Julia brushed it off saying it was just a cold chill. Natalie went back to watching the movie and Julia sat there aroused. That felt way better than she thought it would. It was time to give you a "reward". A nice big one she had been saving up for a while.
The hero of the movie was fighting off an army of henchmen that the villain threw at him. The action was ultra-violent. With a chainsaw in one hand and a gatling gun in the other he tore the enemies to shreds. Down below, after countless struggles you finally pulled your head out of the giant asshole. You wiped the sludge off your mouth and took a long breather. The main character blew up a tower with his rocket launcher. You could hear muffled gunshots and screaming from the movie, along with something else. A faint organic groan in the distance, growing louder and closer. This worried you. The hero punched out several soldiers and then stuffed a grenade in another's mouth before pushing him into another room. "Ha ha! OPEN WIDE!" Julia laughed. You waited, horrified. You prayed that her ass didn't clench on you. Sure enough the hefty rump squeezed tight, and the bowels growled above. Julia chuckled to herself a bit more. She was going to fart all over you and down your throat.
Hesitantly you opened your mouth until it was as wide as it could go. Sticking out your tongue you gave her asshole a light lick, proving that your mouth was really open. She got the message and leaned back into the couch. The weight of her huge ass crushed your body and pushed you snug against her hole. The monstrous anus gurgled in front of you, getting ready to deliver its steamy package. You laid there with your jaw crushed by Julia's big butt, the immense force of it preventing your mouth from closing even a little. More ass liquid dripped in your mouth, you had to swallow the gross juice or risk choking. Julia wiggled a bit in her seat, loosening the gas inside her and grinding her butt all over you. The huge globes spread and gave way for her ass to sink further into the couch. Tears ran down your face ass you heard her gas reach her backdoor. The anus that was already tight against your mouth filled with gas and expanded in size, forming a seal around your lips. With Natalie completely unaware of what was going on Julia was ready to let loose.
There was a small gas leak followed by a huge explosion. The heat was unbelievable. The hero jumped off the island cliff and grabbed onto his buddy's helicopter, while the base blew up behind him. It was the climax of the movie. He gave a cool one-liner about that being his last cigarette and a loud guitar wailed. That was the moment Julia picked to unleash her silent but deadly fart on you. The sticky anus slowly dilated and her thick hot gas filled your mouth and made its way down your throat. Instantly the torrent of moist smelly air filled your lungs and threatened to keep going until you burst. Luckily your lips broke free of their anal seal, the overflow of Julia's gas spilling out the sides. She skillfully kept her anus only slightly open so her fart would come out silently and slowly. She had a lot of gas to expel, and she was going to make you taste all of it.
Continuously her steaming hot fart pounded the back of your throat. You could taste her gas get heavier as it came from deeper within her bowels. The massive pulsating anus was still partially inside your mouth, pumping more and more of her murky gas into you. The drooling butthole vibrated and sputtered, coating the walls of your mouth with sticky rectal slime. Horrifically the anus widened open, increasing both the volume and speed at which her fart blasted you. Roaring winds burst from her ass quietly hissing inside your mouth. The tail end of her fart came from the deepest end of her bowels and was thick and humid. It was so hot Julia felt a burning sensation from her asshole. The moisture stuck to your tongue and you couldn't taste anything but her farts.
The movie credits rolled and Julia remarked "That was intense. I feel like I can finally BREATHE." Then she clenched her cheeks one last time. The anus popped out your mouth and she sat up slightly, giving you back freedom of movement, though your space was limited. Reluctantly you breathed in the cloud of gas that hovered around you. It was by far the worst fart you had ever experienced. Even though it was over the stench hung inside Julia's ass giving you little else to breathe. You started to feel light-headed from the huge amount of methane this girl had happily pumped into you. At this point your punishment had gone on too long. This was torture.
What happens next?
