WARNING: this is a fart fetish story

You were invited to Gabriel’s house to help him get ready for recording the next video for his web channel. You are doing your best at preparing the decorations and setting them up in a way that they would look good in the light from the small studio lamp that is now present in the archangel’s room (Gabriel sure is serious about increasing the quality of his content).
He hoped over to you, holding some cutouts in his hands and giving you puppy eyes: “Anon, pleeease hang these letters on the wall behind my seat too! They are ESSENTIAL! They will help us get just the right vibe, and…”.
“Alright, alright, hand them over”, - you put a stop to his talking before it gets worse. Still, it’s sort of adorable to watch Gabriel be this joyous and energetic when getting ready for the shot - especially after the last time when he got salty about the negative comments.
“And I will check on the micro”, - Gabriel mutters to himself. As he bends over to inspect the accuracy of the settings, you hear a deep squeaky sound. You turn to Gabriel and see him freeze in a wooden unnatural pose, micro stand is still in his hands, but his face is now expressing something new. His cheeks are slowly brightening in colour, eyes are wide open, and lips are tightly pressed together.
“Gabriel? Did you just fart?”.
Gabriel snaps his body around to face you, frantically waving his arms in a negative motion: “N-no! I ‘d never! Angels don’t fart, Anon, didn’t you know that?”. Despite his obvious lying and the nervous laughter that follows those words, Gabriel is so quick to respond to your provocative inquiry. Almost like he knew you’d ask him that. That’s when you notice his belly looks plumper than usual, which is showing even through the thick fabric of the suit he’s wearing.
“Oh, right, sorry, must have been my imagination”, - you decide to humour him for the time being: “Hey, I’ve still got to check if the new editing software is going to work. Wanna sit on my lap as I do?”.
That puts Gabriel in a better mood – he likes being on your lap. So in a fraction of a second, you feel his plushy bum dropping down on your thighs and his unruly 'cow-licked' yet soft hair tickling your chin. You hug around his torso with one arm, giving the small archangel a little squeeze to hold him close, and he responds by pressing his cheek into the base of your neck.
After you are almost done with the software, a crude bubbly rumble emerges from Gabriel’s belly, going on for about 4 seconds as you both sit awkwardly, listening to it.
“Gabriel… I can see that you have bad gas. You do realize that it’s not wise to start recording when you risk majorly embarrassing yourself in front of your viewers? We are going live after all”.
Gabriel is fumbling with his fingers, a bead of sweat running down his forehead: “Crikey… You are right. I just know I’m about to start f-farting like crazy. I feel like a blimp with all this gas inside of me!”.
“Then don’t hold back”, - you nuzzle Gabriel’s head lovingly: “Just let it out, right now”.
“Like this?”, - Gabriel protests, looking at you with worried eyes and preparing to wiggle out of your tight hold: “On your lap? B-but…!”.
“It’s alright, Gabriel. I don’t mind. In fact, I thought it was cute when you farted earlier~”. Gabriel pouts, offended by you bringing that up, causing you to chuckle at the face he’s making.
“Oh, alright”, - Gabriel finally agrees and leans to the side, his torso resting on your body. Your lap gets burned by a hurricane of hot boiling gas that leaves Gabriel’s ass with a wet spluttering sound. The archangel fully throws himself into your arms for comfort, eyes still wide and bearing the expression of a nearly traumatic shame, and you comply, giving him a warm embrace.
“Geez, that was wet. Are your pants alright?”, - you tease Gabriel, and he frantically mumbles something incoherent, before finding the strength to say: “Y-yes. I think they are fine”.
Then, with a great heat that washed over your thighs, comes the smell of garbage with small hints of something sweet mixed in, but that second scent is just as twisted as the other one. Gabriel’s perturbing fumes arise and ripen the air around you both more and more until every sniff you take is practically concentrated fumes.
Gabriel is unpleasantly surprised by how rank his gas is. His eyes start getting filled with tears of anguish, and you know you better hurry and comfort the archangel before he starts crying.
“Anon, I’m so sorry for all this stench! I should have known better than to fart near you!”.
You look at him and openly take a whiff of the aroma, your face showing a pleased smile. Gabriel stares at you with a dumbfounded expression, holding his nose to avoid the smell.
“Don’t worry about it Gabriel. I like your gas. You focus on getting rid of it, and I promise to sniff up the results to clear up the room”, - you wink at him.
“Oh….”, - he breathes out, not sure what to think about your sudden quirk: “Well then, if you really don’t mind”.
You hold him close and plant a firm loving kiss on Gabriel’s soft cheek causing the archangel to break into a wide grin: “I don’t. I love everything that comes from you, Gabriel. Say… Can you stand up and turn your back to me? I’d love to sniff it right from your butt. That way you won't have to smell your gas too”.
Gabriel blushes scarlet red, but figures it wouldn’t hurt to do as you say. Once his tushy is in front of your face, you grab it with both hands, tracing Gabriel’s hips soothingly.
“So, I fart.. Now?”, - Gabriel asks like he’s not exactly sure you can handle it.
“Yep~”.
Gabriel grunts and pushes out a powerful buzz that is getting wetter all the way to the end. As your nose catches the winds as soon as they emerge from his butthole, you experience how foul they are in their pure undispersed glory. Your sinuses are majorly overloaded, so, against your will, you turn your head to the side and start coughing.
“Anon, are you alright?”, - Gabriel worries: “It didn’t burn your nose off, did it?”.
“Wow, Gabriel. I suppose it didn’t, but still… What the heck did you eat?”, - you tease the archangel, fanning the air in front of his ass.
Gabriel smiles shyly: “I had some berries from the Eden garden. They were so ripe and colourful and glistening in the sun… It’s one of those times when I just can’t resist them. Too bad I’ve got a weak stomach tolerance to berries”.
“Yeah, I can smell that”, - you laugh.
“Should I waft the gas away with my wings?”, - Gabriel asks. He’s already in a better mood, with just a small blush staying on his face.
“Nope! I’m fine”, - you say as you continue drinking the remains of the deadly smell: “I just needed to get used to how strong your gas is up close”.
“Is it alright if I fart again?”, - Gabriel asks.
“Of course, bring it out and see me take it no problem!”, - you boast.
Gabriel rubs his belly and unloads it again. A series of wet lengthy crackles are being pumped out in your face. You part your lips this time and get a mouthful of the humid berry-garbage-scented rotten gas. It attacks your tongue with flavour akin to rotten ham glazed with something like syrup and… the sour garbage undertones are there as well. You savour it with your tongue and swallow the thick gas puff. Your lust drives you to start licking the orange-haired archangel’s buttcrack, allowing more hot wind torrents to burst right into your mouth cavity and down your throat, burning all the way down. You don’t care that Gabriel's ass is covered by the pants’ fabric and that you are slobbering all over it, you just want to let him know what his gas does to you.
“Ah, Anon! Now you are tasting it! I had no idea you’d be this enamoured by me farting! It almost helps me feel a lot better about this!”, - Gabriel gasps, pressing his fists into his chest modestly, his ass letting out one final whiny fart that punches the tip of your nose.
“See? I love EVERYTHING that comes from you, Gabriel. Everything your body can offer too~”, - you moan.
“That phrasing is a bit odd, Anon... Anyhow, I think I’ve gotten rid of all the gas”, - Gabriel says, looking aside. He steps away from you, breaking his hips out of your grasp and smiles: “So, we can start recording now? Say, are you feeling alright? You sat in the midst of my gas for so long…”.
“I'm perfectly fine. Couldn't have been better~”, - you still have that dopey expression on your face. Ignoring the smell that comes from your skin, Gabriel leans down and kisses your cheek in gratitude for helping him relieve his horrible bloating.
