Can I get something for Shinji or Sosuke from before TBTP arc?

With a lieutenant reader (from another squad)

Tagging @imaginingbleach since this was your request! I'm glad you asked this because I've had an idea tinkering in my head about a Aizen/Reader/Shinji concept!

TW: alcohol, oral, this gets NSFW near the end but isn't really smutty.

You let a sigh of relief as the warm, soothing water of the hot springs washed over your exhausted body. It was that time of the year where your squad and another would be temporarily relieved of duties, to “boost morale.” To you, this was a long-winded way of saying “mandatory vacation.” Unfortunately, only two squads at a time would get this vacation, and Head Captain Yamamoto would decide where these squads would go. To no one’s surprise, he selected an onsen retreat, and your squad along with Squad 5, would be on vacation.

Your mind drifted further and further away as you relaxed in the hot spring. You decided to take a later dip compared to the rest of your seated members who went in earlier. You could hear them faintly playing games a few rooms away, but for now, you were enjoying the silence.

You jolted up as you heard a loud voice, “Oi, Sosuke – don’t be fuckin’ weird and wear your glasses in the hot spring.”

Oh it’s Captain Hirako and Lieutenant Aizen you relaxed again, hoping the rest of their conversation wouldn’t be as loud. You wanted to enjoy the silence for a bit longer.

“I don’t know why you would think that, Captain. It’d be hard to see with them on.” Lieutenant Aizen said in a monotone voice.

“You’re pretty fuckin’ weird Sosuke. Don’t know what you’re thinkin’ in that head of yours.” Captain Hirako said in a pointed tone. Ugh you thought to yourself, can they not fight tonight? You had heard rumours that sometimes Captain Hirako and Lieutenant Aizen butted heads, but if this was it…

It was so childish?!

“You’re one to tal-“

But before their fight could drag on, you peered over the divider and shushed them. “Please keep your voices down! It’s already late.”

Captain Hirako grumbled an apology, but this was the first time your saw Lieutenant Aizen without his glasses. He gave you a pointed glare. You were taken aback by how sharp his eyes were. “Our apologies, Lieutenant. Enjoy the rest of your evening.” Lieutenant Aizen said, with a soft tone even though his voice did not match the intense glare he gave you.

You slid back down to your spot in the spring and leaned back, closing your eyes to enjoy the warmth again… until you heard grumbling and harsh whispers on the other side of the divider.

It was already so late, what could they be fighting about at this hour?

“Is there a problem?” You asked through the divider.

“Don’t worry about it, Lieutenant.” Captain Hirako said in a dismissive tone, glaring at Lieutenant Aizen.

“Well you two have been grumbling about something since you came in, so is there a problem?” You asked, not wanting to hear any more of their inane bickering.

“It doesn’t concern you, Lieutenant.” Aizen said in a sharp tone.

“It does concern me if I have to hear about it when I’m trying to enjoy my vacation!” You harshly whispered, not wanting to draw attention from your respective squads.

Lieutenant Aizen sighed and pinched the bridge of his nose, and you thought you heard Captain Hirako mumble out, “this is your fuckin’ fault, Sosuke.”

Aizen sighed, keeping his eyes closed, “If you must know, my captain seems keen on blowing our squad’s vacation budget on a ridiculous karaoke device.”

Aside from the gentle waves of the hot springs, there was silence between the three of you.

“…Are you serious?” You asked. This was one of the most ridiculous things you’ve heard.

“Sosuke, you just don’t get it! A night of relaxing, sipping nice sake, everyone on their merry way, why not sing our hearts out?” Captain Hirako explained, as if he was trying to sway your opinion.

“That does sound nice Captain, but I don’t understand why you’re insistent on the device that is out of our budget.” Aizen said, in a matter-of-fact tone.

Still behind the divider, you sighed, “do either of you like to sing to begin with?”

At the same time, both of them said “no.”

You let a loud, exasperated sigh, “then why are you two bothering yourselves with this!?”

“Lieutenant Aizen over here says I can’t sing for shit.” Captain Hirako said, glaring at Lieutenant Aizen.

“Well, you can’t sir. I’ve heard what you’ve called singing, and I don’t want to subject our squad to that.” Liueteant Aizen said, trying to end the conversation.

You quickly wrapped a towel around yourself as soon as you heard rustling and realized Captain Hirako left the springs. You saw him peer over the divider, trying see if you were still there.

“Lieutenant, why don’t you humour us and be the judge of it.” Captain Hirako asked, grinning at you.

You heard more rustling and noticed Lieutenant Aizen’s silhouette through the divider.

You didn’t really have any other plans for the evening, so why not humour the Troublesome Duo?

“Sure.”

Captain Hirako secured a private room for the three of you, as you poured him a chilled bottle of sake as a gift for his hospitality. Lieutenant Aizen went to procure the infamous karaoke device from the onsen hosts.

You never really spoke to Captain Hirako much, he always seemed a bit busy trying to defend himself from Lieutenant Hiyori Sarugaki’s pranks. From what you knew from other squad members, he was relatively approachable, but most members preferred reaching out to Lieutenant Aizen first.

Lieutenant Aizen hadn’t arrived at the room yet, and you felt the awkward silence grow between you and Captain Hirako. “Are you enjoying your vacation, Captain?” You asked, trying to make small talk.

Captain Hirako propped his face in his hand as he stared out the window, boredom glazing his face. “It’s alright. Head Captain Yamamoto doesn’t like to think outside the box that much though.”

You laughed, “I agree. It would be nice for a different kind of vacation. Is it wrong of me to assume, that Lieutenant Aizen and you agree on that matter?”

Captain Hirako gave you a small smile, “yeah, somethin’ like that.”

“I don’t mean to pry, so please excuse my rudeness, but do you two always argue like that?” You internally winced at the question, wondering if you were drinking too much sake too quickly.

Captain Hirako remained unphased, “we have some good days, and some bad days. Tonight, believe it or not, was a good day.”

You couldn’t stop yourself from grimacing, “you call this good?”

Captain Hirako shrugged, and sipped his sake, watching the night sky through the window.

You heard gentle taps on the sliding door frame, as Lieutenant Aizen entered. You never noticed how big he was. His presence was largely felt in the room.

“I negotiated for one hour of singing, Captain.” Lieutenant Aizen explained, as he began to set up the karaoke device. “If you,” he said, pointing towards you, “don’t like his singing. Then I’m not getting him this device for our squad dinner tomorrow.”

He is taking this a bit too seriously. You thought, taking a large gulp of sake. Once the device was ready, Captain Hirako stood in front of you two, tapping the device to find a song to his liking.

Lieutenant Aizen tapped your shoulder, gesturing to the sake bottled. Although moments ago you told yourself to stop drinking for the night, now you wanted to have fun and enjoy your vacation. The sake was incredibly smooth too. You brought your cup towards him and noticed how slender and long Lieutenant Aizen’s fingers were.

He really is handsome… but too serious. You thought to yourself, your cheeks warming to the thought of him.

But before your mind could wander, Captain Hirako began his song. You were expecting something outrageous but… it wasn’t bad?

Maybe not the best singer, but he could keep a decent tune.

“I like this song, Captain Hirako.” You smiled at him, bringing your cup towards him as a cheer. “I think your squad will like this too.”

Captain Hirako kept singing, some songs were better than others, which you and Lieutenant Aizen pointed out. The hour was nearing its end, and you realized how close you were to Liuetenant Aizen, as you leaned into his arm.

Surprisingly, he didn’t pull away from you, if anything, brought you closer to him.

You couldn’t help but smile when you realized how close you were to him, so many people would kill to be where I am right now.

You weren’t sure if it was the sake (you had stopped drinking after Captain Hirako’s third song), or the moonlight filling the room, but even Captain Hirako looked a bit different. You noticed how luxurious his hair looked, and the toned body under his yukata.

But something else also dawned on you, “you two haven’t fought during this whole hour.” You said, amazed at the two of them.

Captain Hirako smirked, “well will ya look at that? Maybe you’re our lucky charm. What do you think, Sosuke?”

You let out a gasp as Lieutenant Aizen brought you into his lap, your back towards him. “She certainly knows how to keep you from making rash decisions, Captain.” To which Captain Hirako laughed.

“Have you two… done this before?” You asked, sensing an air of familiarity, as you felt Lieutenant Aizen’s hands roam your body. He gently turned your head and gave you gentle kiss on your lips, startling you. Gentle kisses became more intense until you pulled away from him, with both of your faces slightly flushed.

“Eh…” Captain Hirako said, kneeling down in front of you. Guiding your face towards him. “Sometimes. Only when we’re in a ‘good’ mood. Although I’m the better companion” Captain Hirako chuckled, running his thumb over your kiss swollen lips.

“That’s not what Lady Sayuri said last time.” Lieutenant Aizen murmured, as he began to untie your yukata. You could feel Lieutenant Aizen’s erection growing.

Captain Hirako brought his face close to yours, nipping at your ear. Lieutenant Aizen’s light touches roamed your body, grazing your breasts over so slightly. A soft moan escaped your lips as he began to pinch your nipples. You felt Lieutenant Aizen’s breath against your other ear, “maybe you can judge which one of us you prefer”.

You nodded your head, watching in a trance as Captain Hirako peeled your yukata and undergarments off your body.

You couldn’t help but smile watching Captain Hirako lower himself on to you. You watched him with half lidded eyes as you felt his tongue give a swift lick to your sensitive clit.

 This vacation was sure to be the best one yet.
