Work Text:
Hijikata was incredibly irritated right now. It was three or four in the morning in Kabukicho, he had just finished his patrol, and was on the hunt for a vending machine that sold his favorite Mayoboros. He was out of mayonnaise and had smoked his last cigarette hours ago, and he needed something to sate his oral fixation now.
After weaving through some side streets and alleyways, he finally saw it. Like a beacon in the dark, he spotted the bright glow of a cigarette vending machine, and as casually as he could, sprinted towards it.
“Come on, come on.” He muttered to himself, eyes searching through the packs lined up for his brand. When his eyes had gotten to the last row, he started his search again, thinking he must have missed the row that held his precious brand of cancer sticks. And then again, one more time, his eyes scanned desperately for the beautiful red script that read ‘Mayoboro’ to no such luck.
Now, Hijikata usually responds rationally and calmly to high-stress situations; this, however, was not his most dignified reaction. Taking out all of his pent up rage out on the poor vending machine, he kicked and screamed, pounding on the glass cursing everyone that he could think of that had led him to this situation: the guy who restocks the machine, Sougo, Yamazaki for not getting him another pack and bottle of mayo earlier, Sougo, the person who bought the last pack of his favorite brand, and of course, Sougo, again, for good measure.
“Who the hell is making all that damn noise?” A very annoying and very familiar voice called out nearby, followed by the sound of garbage bags shuffling and empty bottles rolling. “Can’t a guy pass out in an alley in peace anymore?” A couple meters away emerged a drunk, or possibly already hungover, Yorozuya who had been napping away after drinking his heart out earlier that night.
Hijikata groaned; of course he would run into the Yorozuya when he was peak angry, annoyed, and in desperate need of something, anything, in his mouth to take the edge off.
“Well, well, well, if it isn’t Oogushi-kun waking up the neighborhood with his loud, tax-robbing voice.” Gintoki taunted, looking at the disgruntled man and then at the vending machine, putting two and two together. “What’s wrong? Are they out of your cancer sticks? Is that why you’re ruining Gin-san’s nap, because you can’t get your oral fix in?” Still feeling a bit buzzed, he stumbled a bit closer to the officer, smirking at his pissed off sour expression, and wanted to tease and push just a bit more. “Ya know Hijikata-kun, if you want something in your mouth so bad Gin-san’s got a lil somethin’ you could use.” He said smirking, half teasing, half hoping, wiggling his eyebrows at the other man to top it all off.
Maybe if this were any other time or place, Hijikata would have immediately punched the bastard for even insinuating such a thing; but right here right now, his mouth was watering at the possibility of satisfying his horribly demanding, desperately needy, oral fixation. And besides, it wasn’t exactly his first time sucking dick, and hell, he’d have probably done this sooner with the Yorozuya if he wasn’t so intent on being such an annoying prick to him all the time.
He roughly pushed the Yorozuya up against the alley wall and soundlessly sank to his knees, smirking at the astonished, wide-eyed face of the other. He chuckled dryly, replying, “If you’re offering, then–” he made a ‘get on with it’ gesture at the other’s hips. “Take it out.”
Still in a state of somewhat disbelief, Gintoki scrambled, hastily lifting his yukata, not even bothering with the obi or belt, and unbuttoned and unzipped, pushing both his pants and strawberry boxers down just enough that his cock emerge, already showing signs of interest in what was about to happen. He hadn’t been blown in ages, and certainly not from someone as good-looking as the Vice Chief.
Hijikata stared at it. “This is not a ‘lil’ somethin’’ you bastard.” Hijikata grumbled, repeating the words the other had used. Gintoki was large, and he wasn’t even hard yet. Somehow though, that fact excited Hijikata; thinking about how full his mouth was gonna be with that thing in it made him shiver in anticipation. He grabbed at it, stroking slightly, and popped the head in his mouth, sucking lightly while swirling his tongue. It hardened quickly, and Hijikata started to take more of it in his mouth, bobbing his head slowly, his lips meeting his hand, still fisting around the base.
Gintoki moaned, low and long, not taking his eyes off the sight below him, still slightly not believing what he was seeing. Hijikata looked up at him through his lashes, holding his gaze, before taking his hand off and moving down the whole length, cheeks hollowing as he sucked hard and swallowed, his throat squeezing impossibly tight around it.
“Aah, fuck!! … Fuck, Hiji–!” Gintoki’s head tilted back, hands clenching tight into his yukata that he was still holding out of the way, his hips bucking jerkily and involuntarily into the officer’s mouth, getting him a glare from the other as he choked a bit. Hijikata brought his hands up to grip at Gintoki’s hips, his fingers and nails digging down hard to hold him still; he was trying to savor this, after all, since he was doing this for his own personal satisfaction more so than to get the Yorozuya off. He pulled his head back slowly, lips still suctioned tight around that dick, until he released it with a pop.
“Oi, this isn’t some free throat fuck,” he said, voice hoarse but still commanding. “You’ll take what I give you, got it? Be a good boy and stay still.”
“Sir yes Hijikata-kun sir!” Gintoki nodded eagerly hoping to please him and hurry it up, only somewhat proud he didn’t immediately start begging for Hijikata to start sucking him off again. “Gin-san will let you suck to your heart’s content.” he added teasingly, well, more like pleadingly, really.
Hijikata narrowed his eyes at the other, but kept his retorts to himself; he had better things to do with his mouth than bicker with the Yorozuya, like sucking on that massive cock straining in front of him. He took it in his mouth again, and started to really go to town, closing his eyes to concentrate on the pleasure and sensations. The weight and taste on his tongue, its slight curve and thick veins, the way it filled his mouth completely, hitting deep down his throat when it was all in; all of it was so good and so satisfying for Hijikata, like finally scratching an itch just right. He moaned appreciatively around it, the vibrations making Gintoki cry out and curse.
He sucked fast and hard, bobbing his head from base to tip like a champ, pleased by the sounds of pleasure and desperation coming from the other man, echoing those moans every time his mouth was filled perfectly and just right, making his toes curl and eyes roll back. This was exactly what he wanted, what he needed to sate his aching and troublesome oral fixation.
Gintoki couldn’t believe it. He was getting the soul sucked out of him by the damn Shinsengumi Vice Commander of all people, who was surprisingly not only experienced in the blessed artform of cocksucking, but was a top tier throat-goat. “You… You’re too fuckin’ good at this, fuck.” He muttered, a sweat breaking out across his brow as it took all of his willpower to not touch or thrust at the other man. “Hi-Hijikata-kun, I’m… I can’t,” He warned in a low voice, his orgasm impending quickly.
Hijikata hummed in acknowledgement, disappointed that it was ending already, but thrilled as this, too, was something he wanted. See, his oral fixation didn’t stop with just the need to have something in his mouth or to suck at, he also needed something to swallow. Mayonnaise was obviously his preferred substance of choice, but cum also worked as a convenient substitute.
Gintoki could barely keep himself standing upright; his thighs were trembling, his knees close to buckling from how good it felt, couldn’t focus on anything other than the pure white heat coursing through him, threatening to spill at any second. He looked down at Hijikata’s flushed face, the complete and utter bliss in his expression, his pretty spit-glossed lips stretched wide around his cock; it was all too much. He came suddenly, without warning, into Hijikata’s waiting mouth, who happily swallowed down his load, sucking and licking at the tip until every last drop was accounted for, until Gintoki was soft and whining from hyper-sensitivity.
Hijikata finally released the other, feeling satisfied and content at his handiwork. This should sate his need until he got back to the barracks, where he always had a stash of mayo and Mayoboros at the ready. He stood up, dusted himself off, and subconsciously patted his coat pockets for a pack of cigs, frowning when he remembered that he was out. A post blowjob cigarette was immaculate, and his lack of smokes was really putting a damper on his recently improved mood. He started to walk away when Gintoki called out to him.
“Hey, wait dammit! Don’t you want me to, ya know, return the favor?” He asked, making a crude gesture with his hand and mouth. “Might not be as good compared to your talents, but I’m pretty confident I could get you off.”
Hijikata stopped; he was so focused on his mouth, he didn’t even realize he was hard. He contemplated the Yorozuya’s offer. Honestly, the only thing he wanted right now was a cigarette. And besides, his boner would probably just go away on its own, it’s not like he had to take care of it. He was about to decline, when–
“I know a hotel that sells Mayoboros in the lobby.” Gintoki offered.
“... Lead the way.”
