The land of the samurai. There was a time, long ago, when our country was called by that name.

"Wait… wait… this narration…" Gintoki murmured. "This is only a fan fiction written by some random fan, we don't need the original narration, just get going with the story already!"

Hijikata x Gintoki

Warning : boy x boy, yaoi, BL, semi non-con

You've been warned, proceed at your own risk.

As usual, today was another no-job day for Gintoki. He wasn't a NEET, he was just simply on a stand by mode… or power saving mode. Kagura had been at Shinpachi's house since early in the morning, looking for free food. Shinpachi, as always, his protest was simply ignored. On the other hand, his sister didn't really mind if Kagura came over and had a meal together. She would gladly cook tamago yaki for everyone, it didn't look like a tamago yaki though, no matter how hard you look at it. It was a dark matter disguised as an egg roll.

Gintoki was lying on his couch while watching TV peacefully when suddenly there was a voice calling for him on his door. Grumpily, he dragged his sluggish body to the front door. Scratching his head, he opened his door to be greeted by none other than Hijikata and a teenage girl standing on his side.

"What are you doing here? It's too freaking early to collect tax you know!" Frowning, Gintoki snarled at Hijikata, showing his displeasure.

"What are you talking about?! It's already 12.30 pm, you know!" he snarled back, his vein could be seen popping on his forehead. "Anyway I'm not here to collect tax, you idiot, I have a job for you."

"Huh?"

Minutes passed since Hijikata and the teenage girl were permitted to sit on the living room couch, but none of them started to talk about the job Hijikata mentioned before.

"So, are you going to sit still like that all day long? What job do you need me to do?" Gintoki started the conversation, losing his patience.

The teenage girl looked at Hijikata as if asking for permission to talk, Hijikata simply nodded while lighting up his cigarette. The girl even though received the permission she was looking for, she was still hesitant and her body fidgeting uncomfortably.

"Uhm… My name is Bella…" she finally started, "I came from Omega Planet…" She paused, her voice was slightly trembling. "On earth there are two genders, male and female, but on our planet, we also have sub-gender besides those two. Alpha, omega, and beta."

Gintoki was listening seriously, his dead-fish eyes fixated on her frame. He was hoping to get a high score job this time, since his client was an amanto. Not to mention his rent payment was due next week.

"Recently, my brother, Daato and his mate obtained a gender swap prototype that was developed secretly by an underground organisation. They asked me to keep it safe and hide on earth while they take care of that organisation," she continued, "But, since last week, I've been chased by that organisation's member and nearly killed. Thankfully, Hijikata-san saved me from them."

"We want you to keep the prototype for the time being," Hijikata stated after the girl finished her story.

Gintoki was dumbfounded by the request, Hijikata was a cop, Shinsengumi himself, why would he ask Yorozuya to do this kind of job. It was as clear as daylight that it was an intergalactic problem. He should do the job himself! He screamed in his head. "Why would you ask me to do the job, it's clearly your job in the first place. What, are you trying to enjoy your our-tax-paid salary without working your finger to the bone?!"

"Watch your mouth, Gintoki! I'd do it myself if I could!" Hijikata gritted his teeth, somehow trying to contain his fury.

"Hijikata-san worked hard to protect the prototype, please don't blame him," the girl came to his defence. "He was exposed to the prototype and had his gender swapped, but we don't know yet which gender he is right now," she sighed, "If all of the Shinsengumi's members were exposed, it would be extremely hard to keep it protected, that's why I asked Hijikata-san to find someone who isn't Shinsengumi to do the job."

Gintoki's eyebrows twitched, he was left speechless hearing the girl's explanation. "Wait a minute, on the other words, I might get exposed too?! Oi, oi, miss, the least thing Gin-san wants is to lose his beep, you know!"

"Hmm? You won't lose your beep even if you're exposed though."

"The censors made it seem like a dirty word… Well, you won't do this alone, I'll be staying with you until Bella's safety is guaranteed and she can go back to her planet," Hijikata added.

"That's the worst, who would like to work, moreover stay with you, Mayora?!"

"THAT'S MY LINE! WHO WOULD LIKE TO STAY WITH YOU, DAMN TENNENPA!"

"WHAT DID YOU SAY?! DO YOU HAVE A PROBLEM WITH MY WAVY HAIR?! I AM TOO, WANT A STRAIGHT HAIR AS A PROTAGONIST, YOU KNOW!"

Hijikata and Gintoki both were grabbing at each other's shirts' collar, gritting their teeth, ready to fight.

"Uhm… so… are you accepting my request?" Bella's voice was low, but both of them heard it and ended their fight immediately.

"Well, it couldn't be helped, I'll do it," scratching the back of his head, Gintoki agreed to her request, while Hijikata sighing heavily.

Fixing his uniform, Hijikata continued, "Bella will stay at Shinsengumi's headquarters for a while, I'll be staying here with you, and it's better to keep Shinpachi and Kagura and Sadaharu away for their safety as well."

"This is a troublesome job, you better pay me nicely once the job is done!"

After the agreement, Hijikata dialled Sougo to come and pick up Bella. He explained to him that he would be staying at the Yorozuya for a while until both Bella and the prototype were safe. Yamazaki would take care of their daily needs during his stay since they most likely wouldn't be able to wander around freely.

Hijikata ended the call with a deep sigh, while Bella took out a silver ping-pong-sized ball from her pocket. She handed it to Gintoki carefully. "This is the prototype, make sure to keep it safe, if it's break, even a small crack, you'll get exposed and your gender will be swapped."

"Oi, oi, are you sure it's a wise decision to keep it here? It sounds so dangerous, Gin-san don't want to lose his balls, you know," hesitating, Gintoki received the ball with both hands, scared that if he ever broke it he would lose his most important treasure.

"It's not that fragile, though, it's quite a strong ball, you can even use it as a ping pong ball," Bella assured him while smiling sincerely.

Hours later.

"Oi, Hijikata! Get the dinner ready!" Gintoki demanded from the living room while watching the weather girl, Ketsuno Ana on TV.

"Stop ordering me around! Get your lazy ass here and do it yourself!" Hijikata snarled from the kitchen.

Gintoki walked lazily to the kitchen, he peeked at Hijikata from the door frame. "You're staying at my place, so you better work your sorry ass," he stated.

Hijikata's inside snapped, he rushed to where Gintoki was standing and grabbed his collar, "I pay you for your service, you're the one who should work, damn it!"

Gintoki didn't respond, he just stood there when Hijikata grabbed his collar and shook him roughly. The shake made his kimono sleeve sway back and forth and he accidentally dropped the silver ball he put in it.

Both of them were stunned looking at the ball rolling on the floor. Their face paled. He raced to the ball and grabbed it as if to prevent it from breaking only to find a crack on it. Gintoki was at a loss, he grabbed the first aid kit, and pulled out some band aid. Plastering the band around the ball, he panicked, "I thought this ball was supposed to be as bouncy as a ping pong ball! It's freaking fragile as an egg shell, bakayaro!"

"Err…" Speechless, Hijikata only stared at him while he tried to fix the crack on the ball. "We… well, you better calm down, as you can see I'm exposed too, but nothing happened so far," Hijikata grinned awkwardly.

"How am I supposed to calm down?! Gin-san is about to lose his balls!" he yelled in Hijikata's face. He grabbed him on the balls to assure himself, "…ah… it is still there," he commented.

Blushing, Hijikata slapped Gintoki's hand away, "Where the hell do you think you're touching?!" he screamed.

"Sorry, I was just trying to find evidence to prove your innocence."

"And what the fuck do you mean by that?!"

And the day passed just like that. Fortunately for Gintoki, he didn't lose his balls like he had imagined, but his fortunes would run out eventually.

On the next day, Gintoki couldn't stop complaining about how hot it was all day, while Hijikata tried to put up with his complaints. He put a wet cold towel around his neck to ease his own burning body.

The weather forecast stated that today would reach 27 degree Celsius at most, but somehow they felt like it reached 37 degrees. "Don't you think it has to do with the ball?"

"I don't know, probably it's your place's bad ventilations."

"Don't blame it on other people's stuff, damn Mayora."

With that they spent the rest of the day, complaining, arguing, just like an old married couple. Once the sun set, Gintoki locked himself in his room, and didn't even bother to turn the light on. His body was burning and he couldn't think clearly. He stripped off his usual attire and put on his jinbei, he laid down on his futon. Panting, he barely could stand the heat.

"Maybe some water would do," he murmured to himself, picking himself up, he stumbled forward, landing on his face painfully. Grunting, he noticed that he had no strength to stand.

Suddenly, Hijikata slammed his room's door open, his face flushed, "What is this sweet smell?" he asked, panting.

"The hell you're doing? Get out!"

"Gintoki… it emanates from you…" his eyes glinted dangerously. Slowly he made his way to where Gintoki was, still sprawled on his stomach on the floor. "You smell amazing…" Hijikata sniffed at him, getting closer to his face.

With his little strength remaining, he pushed Hijikata away. He stood up on his wobbly feet with lots of effort only to stumble again and ended up fell on his butt. Grunting loudly, he rubbed his butt cheek to ease the pain.

Suddenly, Hijikata was already kneeling in front of him, he pounced on him and pinned him down. Gintoki's eyes widened in surprise. "What do you think you're doing?" he gasped.

"Your smell… it's driving me crazy…" Panting like a dog in heat, Hijikata discarded his black yukata and left it hanging on his hip, held in place by his obi around his waist. "You look delicious…" he leaned forward, without warning he licked Gintoki's exposed neck.

Gintoki yelped at the sensation, once again he tried to push him away, but to no avail with no strength left in him. Squirming weakly, he tried to escape from this situation. This is dangerous, he thought to himself. "Oi, calm down!"

Hijikata pulled away only a few inches from his face, his eyes wide open as if the eye balls were going to fall from its sockets. He could feel his hot breath on his face. "… no way… did I become an alpha…?" breathing heavily, the reality hit him hard.

Bella told him once that the prototypes contain one type of sub genders each, alpha and omega. The one he broke and the other Gintoki broke. An alpha can smell pheromones emanating from omega in heat, the sweet smell which drives alpha crazy. On the other hand, an omega can sense alpha's pheromone, whether the alpha goes into rut or not, they'll submit to the alpha.

"Wh… what do you mean?" Clueless, Gintoki asked him breathlessly when suddenly he felt something hot dripping out from his private area. He looked at his jinbei's shorts only to find it soaked already. "What…?!"

The sight in front of him drove him over the edge. His reasoning left him, leaving him only with his instinct and desire to dominate. Wasting no time he stripped Gintoki off his pants and undo his jinbei's little tie knot, revealing Gintoki's well built body.

"Oi, what the hell do you think you're doing?!" Gintoki squirmed, trying to hide his unbelievably hard member with his hands. His anal was soaked wet and the tingling sensation inside him was unbearable.

Looking at Gintoki lustfully, Hijikata sniffed him again, drowning himself in Gintoki's addicting scent. He licked his neck again down to his navel. Made his way down south, he pulled Gintoki's hands away and held them above his head. He licked his lips in anticipation, staring hungrily at his pre-cum coated member. He bent over and kissed the head, licked the tip, and finally sucked the whole thing with his mouth.

Gintoki moaned loudly, feeling his staff was being sucked by none other than Hijikata, the Oni no Fukucho. He was screaming in his head to escape, but his body wouldn't listen to his command, enjoying every touch he received from Hijikata instead. "Hi…Hijikata-kun, st-stop…!" His plea wasn't convincing at all when he thrusted his hip up into Hijikata's mouth, looking for warmth, asking for more.

Instead of releasing him from his mouth, he humped and sucked even harder. The frictions doubled the pleasure, as if being electrocuted kind of sensation, he reached his climax. Shoting his seeds into Hijikata's mouth. Without spilling a single drop of his juice, he drank it all, licked his soaked member clean.

He was out of breath after he climaxed, catching his breath, his eyes widened in shock seeing Hijikata gulping his cum. He moaned again when Hijikata's hot tongue made contact with his sensitive member, licking it clean, not letting any juice go to waste.

After licking his member clean, Hijikata leaned closer to Gintoki's face. They stared at each other deeply, holding Gintoki's jaw in place, he captured his lips in a passionate kiss. Nibbled at his lower lip, he asked for entrance. Gasping at the sensation, unconsciously he parted his lips and gave access for Hijikata to jam his tongue inside.

He could taste his own semen that was left in his mouth when Hijikata pushed his tongue deeper in his mouth, exploring every inch of it. Running out of patience, Hijikata rubbed Gintoki's drenched entrance and inserted his index and middle finger at once.

Gintoki mewled in Hijikata's mouth, he jerked his back when Hijikata's fingers were inserted in him. His inside was burning, asking for more, even though his head was screaming to stop. "Wa…Wait, Hiji…!"

He was cut off mid-sentence, when Hijikata pushed his third finger in him. Struck his bundle of nerves inside steadily. "…no…" gasped, "wait…st-stop…" The pleasure was shockingly amazing, but he knew that they should stop right here and there.

Mercilessly, Hijikata kept stroking him, not a single word left his lips, he only focused on the pleasure he inflicted on him. Jamming his fingers faster and harder inside him, he drove Gintoki over the edge. The sound of his drenched entrance being probed echoed in the room.

Thrashing around to escape from Hijikata's unforgiving fingers, he jerked his hips away, arched his back, and pushed Hijikata away, but failed miserably with Hijikata's other hand holding him in place. Moaning loudly, he spurted his seeds all over his torso, he came for the second time only from his back.

Panting harshly, he tried to catch his breath. Hijikata finally released his hands and worked on his own member. Revealing his soaked with pre-cum erection, he positioned himself in Gintoki's wet entrance.

Gintoki's eyes widened in horror when he saw Hijikata pushed in him slowly. He was going to say stop when a cry broke out instead. "Aaaargh…!!!"

Pushing his hard member hard and steady, he could feel the wetness and warmth inside. A single tear trickled down his face, gasping for air, he barely could form a single word, "…it hurts…" finally he choked out.

"It's OK, it will feel good soon," Hijikata promised him while panting heavily. Deepening his thrust, he planted a kiss on Gintoki's lips again, sucking on his tongue, mixing their saliva. He rubbed his inside with his hard member and penetrated deeper and harder. The sloshing sound of their flesh echoed loudly in the room. "Gintoki…"

He couldn't perform any words any more, only a moan of ecstasy escaped his parted lips while gasping for air. He put his arms around Hijikata's shoulder, holding on to him for dear life. Mimicking the gesture, Hijikata embraced him tightly, wrapped his arms around his back, supporting him to stay in his position.

Breaking the kiss, Hijikata's thrust became frantic and uncontrollable, pushed to the hilt, he released his seed deep in him. He sank his teeth on the nape of Gintoki's neck. Feeling the hot fluid being shot in him, moaning at the top of his lungs, he came hard, sprayed his juice all over their stomach. Their sweaty bodies glistened under the moonlight that illuminated the room.

Catching their breath, Hijikata pulled out from Gintoki slowly. His seeds dribbled down his twitching entrance sexily. Lying side by side, still panting for air. "That was amazing…" Hijikata started, he let his gaze fall on Gintoki's figure beside him.

Gintoki, still busy catching his breath, face flushed, he stared at the ceiling blankly. He couldn't believe what just happened, yet he felt incredibly satisfied at the same time. "… it felt good…" he said quietly.

On the next day, Hijikata got a call from Kondo. He told him that the organisation's whole members were already captured and it was safe for Bella to return to her planet. He hesitated to tell Kondo about the prototype, but had no choice except to tell the truth. Bella's shocked voice could be heard over the phone when he informed Kondo that Gintoki was also exposed to the prototype.

Only a few minutes after the conversation over the phone ended, Bella was already standing in front of Yorozuya's door. Out of breath, she stormed inside. "Is Gintoki-san alright?" she asked urgently.

"Well, he's still in his room," Hijikata stated, his face blushing.

"Since Hijikata-san could speak normally over the phone, I figured out that Hijikata-san was probably exposed to the alpha one, that means Gintoki-san was…" she didn't finish her sentence, knowing that Hijikata already knew.

Nodded, Hijikata scratched the back of his head averting his gaze to the side, still blushing madly. Smiling awkwardly, Bella held Hijikata's hands, handing him a black leather collar.

"The alpha rut only comes once and the sub gender effect will slowly disappear in a week, about the omega heat…" she paused, feeling uncomfortable explaining it to an earthling, "the heat will

last for a week and the sub-gender effect will disappear for another week. Tell Gintoki-san to put that collar on his neck during his heat to prevent getting bitten by alphas."

"Huh?" Hijikata's face paled, "What do you mean get bitten by alphas?"

"If an omega in heat gets bitten by an alpha, they'll be a bonded pair, uhm… an inseparable couple."

I messed up, he thought, his face was as white as a ghost. Suddenly, he smelt the sweet scent Gintoki emanated before. He dropped onto his knees, while pinching the bridge of his nose. "I already bit him…" he stated, unbelieving in his own words.

"Omy…" was the only word escaped from Bella's lips while covering them with her hands. "Hijikata-san…" her voice was barely audible, "err… since you two aren't Omega Planet's people, you will turn back to normal eventually once the effect wears off… but, for the time being, since you two already bonded…" She was at loss, trying hard to find the right words to explain the situation, "Take care of Gintoki-san as a responsible alpha!" She finished her sentences.

Agape, Hijikata left speechless while his body grew hotter as the time passed.

"Then… I'll take my leave now, thank you for everything. Pass my gratitude to Gintoki-san too, please! Well, excuse me!" With that said she ran away from the scene as fast as lightning.

"Gintoki…" making his way to Gintoki's room, he was more than ready to make love to him again. He entered the room to be greeted by Gintoki who was sprawled naked on his futon, his eyes half lidded and filled with lust. His groin already drenched with his love juice, ready to be filled by his alpha again.

"…hurry up and hold me…"

End.
