Ana, after a bit of recovery, perked up again and patted her bed, inviting James to lay on his back. They both knew what was next. James got down on his back as Ana mounted on top of him. All James could see was heaven. Ana's ass looked huge from this angle as he cheeks hung down hiding her precious hole. "Ready for dinner?" Ana said, which always made James' limp dick jump. He nodded, as Ana spread her cheeks before sitting down on his face and dropping her cheeks. Her asshole sitting with his open mouth below and his nose barely getting air. Ana started to push, all that air he pumped into her, needing out again.
It wasn't long before a fart came, straight into his mouth as he swallowed it down. "Ahhh," sighed Ana as this was only the beginning. James stuck his tongue into her ass as a thank you, while also getting another taste of her ass, but every time he felt her clench her cheeks, he knew a fart was coming he removed his tongue again. Another fart came and was quickly swallowed again and again and again. They loved this for different reasons. Ana loved being the dominator, using her boyfriend as a slave and fart cushion, while James loved the humiliation of it. He loved how he was willingly letting someone fart into his mouth and he enjoyed it a lot.
Ana got up for a second while James caught his breath, he could barely breathe as her ass was so big. "Just for being late, I'm gonna smother you in my farts," with a wicked smile. She enjoyed smothering, it gave her more power. James liked it too, but it did hurt his lungs. With that, she plugged his nose and sat down again. He couldn't breathe, his nose was blocked so all he could do was use his mouth which was occupied by her asshole. Seconds passed until another fart blasted into his mouth, inhaling it in to try seep whatever oxygen there was. He started to flail a little as he was running out of air, but Ana gave him air in another way. Another blast into James' burning lungs as he squirmed underneath, so much pleasure but so much pain. Ana eventually got up, as he gasped for air for a second before plunging into darkness again. 2 more cycles of smothering, flailing and relief as Ana unplugged his nose and allowed him to enjoy her ass some more.
James went back to licking her asshole smoothly while Ana was pushing out all the remaining air she had left. All while James swallowed it all down for his own pleasure. The tongue assault made her ass open up a little more each time, allowing her farts to just fall out.
With all the pushing of air out, James did notice the farts starting to taste a little more potent. When he thrust his tongue in, he could feel something that did not taste good at all. However, he was powerless underneath a goddess like Ana. She had always got up before it got this far. We were in unknown territory. Ana could feel his tongue not going in ass far, while she was still pushing out any air left. James coughed at the last fart, not even his ass fetish could handle it. But Ana did not care. He was just a chair to him now. He always loved licking her ass and eating her farts from day 1, this was just the next step. James could feel her asshole pucker as Ana could feel the mass moving. Powerless to her actions, all James could do was take it.
