When Dazai told him, he didn't want to believe it.

It was impossible, after all. How could you fall in love with the person whose leg you had torn off?

No matter how much the chestnut-haired man insisted, Chuuya refused to accept it. Until Akutagawa's secretive outings became more evident, and he caught them red-handed.

Or, rather, caught them with their hands on Atsushi.

"The Mafia's dog likes the Agency's Tiger," Osamu casually blurted out during a mission.

"Huh?"

The surprise almost cost him his life. But it was Dazai's fault, really. Who drops news like that while you're disarming a bomb?

"Akutagawa likes Atsushi," he repeated.

Chuuya nervously laughed as he cut a blue wire and tied it to a green one.

"Don't talk nonsense and help me with this damn bomb."

"It's not nonsense, it's the truth," the chestnut-haired man replied, helping him cut the red wire. "And Atsushi feels the same way."

"Dazai, Akutagawa tore his leg off."

"That was a long time ago."

In the end, they disarmed the bomb without losing any of their limbs, and Chuuya stubbornly continued to deny any romance between the two teenagers.

But now, seeing the albino and the black-haired timidly and secretly kissing, he felt his opinion change. And, inexplicably, he was overwhelmed with tenderness towards the young couple.

"Like Osamu and me," he thought. And an excellent idea occurred to him, but to carry it out, he would need his -insufferable- boyfriend's help.

"Is it really necessary for me to say it?"

"Do you want my help or not?"

Chuuya took a deep breath and, sitting on Osamu's lap, said:

"You were right. Akutagawa and Atsushi are dating."

Dazai smirked arrogantly and shamelessly ran his hand along the redhead's thighs.

"And?"

"And I need your help with something," Nakahara finished, shivering at his lover's touch.

"Fair enough. What do you want me to do?"

"For starters, don't talk about this with Atsushi yet. You have very little tact, and you might scare him... or traumatize him..."

"Oh, come on," protested Osamu. "When have I ever traumatized anyone?"

Chuuya raised an eyebrow.

"Are you seriously asking me that?"

"Well, maybe you're right," he reconsidered. "What else do you need?"

"I need you to arrange a date for me with Atsushi," Nakahara replied. "Preferably in a private place where he feels safe."

"A motel?"

"Of course not, idiot! Something more like a restaurant, or things like that."

"Will Akutagawa be there too?"

"Of course. This concerns him as well."

Dazai thought for a moment.

"So, an intimate restaurant, a reservation for three people, and the precaution of not running into people who might make them uncomfortable, is that it?" Chuuya nodded. "I know a place. But it will be difficult for you to afford it."

"Money is not a problem."

"I wasn't referring to the restaurant, Chuuya."

There was no need to ask. Dazai's lascivious gaze made it very clear what he would have to pay and how.

He sighed and leaned in closer to the chestnut-haired man's ear.

"If you hurry up and get that reservation," he whispered, "I can ask Mori to give me the next week off, you know."

Such a tempting proposal couldn't be taken lightly, so Osamu, stealing a kiss, replied:

"This Friday at four o'clock, at that restaurant on the pier. You better get those vacations, Chuu~"

"Yes, yes, I'll do that. Don't worry about it, darling."

Dazai burst into laughter.

"'Sex Education with Nakahara Chuuya'," he laughed. "I'd die to see how you embarrass them."

"You'd die for anything," the redhead retorted. "I'll try not to embarrass them too much. We don't want them to end up like us on our first time."

"Oh, God, no," Osamu shuddered.

They sighed. The plan was set, and although it would cost him, Chuuya was convinced it was worth it.

He would teach sex education to the young lovers.

On Friday at four o'clock, Atsushi anxiously waited for Dazai at the restaurant on the pier. The brunette had told him that he would surprise him on that day, at that place, and the tiger had no choice but to believe him.

However, his heart skipped a beat when he saw Chuuya enter the same restaurant and make his way to the table where he was seated. And it didn't help that Akutagawa was behind Chuuya, looking concerned.

"Damn," the albino thought, "we've been found out."

The mafiosos stopped in front of him, and Nakahara smiled kindly.

"How are you, Atsushi?" he greeted. "May we join you?"

Without waiting for an answer, he sat down in front of the tiger and gestured for Akutagawa to sit with Nakajima. Once everyone was at the table, Chuuya called the waiter and ordered three bowls of Chazuke, two sodas, and a white wine.

"Alright," he said when the waiter left. "Do you know why you're here?"

The young ones swallowed nervously.

"Chuuya-san, if you intend to reprimand us, it's my fault," the raven-haired one spoke immediately. "Therefore, if there's going to be a punishment, let it be for me. Atsushi has nothing to do with it."

"What?!" the detective exclaimed. "That's not true! It's my fault! Chuuya-san, if someone has to be punished, let it be me!"

"Don't talk nonsense! Chuuya-san, I'm your subordinate, so the punishment should fall on me."

"But it was my idea! It was my idea!"

"I don't give a shit if it was your idea! Are you stupid? I'm protecting you!"

"But..."

"Enough," Chuuya interrupted them. "You're giving me a headache."

The teenagers fell silent and nervously looked at each other. Chuuya leaned in closer to them.

"I'm going to ask you something, and I want you to answer me honestly," he warned. "Are you two dating?"

Feeling exposed, they had no choice but to nod. They were already considering the idea of running away or a double suicide when Chuuya leaned back in his chair and said:

"Ah, okay."

The young ones were puzzled by their superior's reaction.

"Is... Is that all you're going to say?" Akutagawa asked.

"And what do you want me to say? 'Congratulations'?"

Atsushi started playing with his fingers.

"But... Is it okay with you?"

Nakahara shrugged.

"Why not?"

"Because we're two men, perhaps?" the raven-haired one suggested.

"Or maybe because I'm from the agency and Ryū is from the mafia?"

The waiter arrived with the drinks. They thanked him, raised their glasses, took a sip, and focused on what concerned them.

"Listen, there's nothing wrong or strange about being gay, bi, pan, or any other LGBTQ+ orientations," Chuuya looked at them with understanding. "So it's not something new. And as for the agency, it's not something new either. Mori and Fukuzawa themselves have their own peculiar thing going on, and it's no secret to them that Osamu and I are dating, just as it's no mystery to us that you two are in a relationship."

Akutagawa nudged Atsushi lovingly.

"I told you. Dazai-san and Chuuya-san are dating," he boasted triumphantly. The albino rolled his eyes and crossed his arms.

"What I mean," the redhead continued, "is that I went through something similar myself

, so don't worry. You have my full support, and Dazai's too."

They smiled. The food arrived.

"So... you're just here to let us know that you know about our relationship?" Atsushi asked.

"Not exactly," replied the mobster. "And that's exactly what I was going to talk about. You guys haven't had sex yet, have you?"

Atsushi choked on his Chazuke and Akutagawa on his soda. They coughed, while Chuuya cracked up.

"Chuuya-san, why do you ask such things?" Akutagawa muttered once he had recovered.

"It's important that you know."

"Why?"

"To prepare you, it can be dangerous to have sex without knowing exactly how it is done."

Atsushi made a face.

"I thought it was easy..."

Chuuya laughed.

"You read a lot of Wattpad, right, Atsushi?"

Both teens looked at each other, rather embarrassed.

"The thing is, I'm here, and I can answer any question." Nakahara took a hand from each of them. "You can talk to me, I promise not to tell anyone. Trust me."

Akutagawa sighed.

"The truth is... That we still don't feel ready to have... That," he confessed, looking sideways at his boyfriend. "Mainly because we're not sure how it's done."

"So," Chuuya smiled sweetly, "what do you want to know?"

"How do you have sex correctly?" Atsushi asked.

"Well, I'm not sure how much the term 'properly' encompasses," the redhead replied. "The important thing about having sex is that it feels good. So I guess correctly means no pain.

⟩⟩But regarding your question, I can tell you that the main thing of all is consent.

"The consent? Akutagawa drank some more of his soda."

"Yes that's how it is. To have sex, the most important thing is that both of you are sure that you want to do it. If one of the two wants to, and the other doesn't, it would be best to wait for both to agree. You can't force your partner to do something they don't want, because that becomes abuse."

"What if I regret it at the last minute?" Atsushi asked uneasily.

«I knew that Atsushi was the bottom one» Chuuya thought, and answered:

"Then you must tell Akutagawa and he will have to stop. It doesn't matter if you are already naked, or even if there is already penetration. If either of you says no, it's no, and that must be respected."

The youths turned red at the word penetration, but Akutagawa still asked the next question.

"What should be done to make him feel better? Or is just sex, anyway, good?"

«At least it doesn't embarrass him so much to say 'sex' anymore»

"Have you heard that practice makes perfect? That saying applies perfectly to sexual relations. Your first time is not going to be the super god of sex, and it will probably be weird. What really makes sex feel good is that moment of intimacy, and the excitement of the moment.

⟩⟩It's also important to stress that you can't have sex just like that, out of nowhere and anywhere. To begin with, since you are men and therefore do not have a vagina, sex is done via anal, which, as you know, is where the poop comes out."

Akutagawa and Atsushi frowned.

"That's why," continued the ginger, ignoring the grimaces of the adolescents, "it is recommended to defecate a few hours before the act, and take a bath to clean yourself with a finger."

"Aren't there... devices for that?" Asked the albino, slightly disgusted by the idea of ​​sticking a finger in there to clean the poop.

"Yes, but they are not highly recommended because they can lacerate the anal walls.#

Chuuya had to force hisself not to laugh at the young couple's expressions.

"How do you put on a condom?" Atsushi asked. "Where are they bought?"

"Condoms are sold in any pharmacy, and they are not expensive. They exist of several types. Please, do not open them with your mouth or with scissors, because the packaging has indicated where to pull so that it opens automatically. Regarding how it is put on, they just have to place it on the penis and fully extend it."

Akutagawa opened his mouth to ask something else, but turned red and closed it without saying anything. However, Nakahara knew exactly what the mobster wanted to know.

"Were you going to say something, Akutagawa?" - Inquired sardonically.

"N-no, nothing," the black-haired lied. Chuuya cautiously approached.

"Do you want to ask about... the size of your little friend?"

Ryuūnosuke's face could easily have been mistaken for a tomato. Slowly and sorrowfully, he nodded.

"Do you know what erogenous zones are?" asked the redhead. The two boys denied. "I recently learned that erogenous zones are parts of the body that provide a lot of pleasure to an individual. There are several, but the main one in men is the prostate, which is only 5 centimeters inside the rectum. So don't worry if you're not very gifted, because that «the bigger, the more pleasure» is a lie."

They finished eating, and ordered fried ice cream for dessert.

"Do you have any advice to give us?" Atsushi asked.

"Don't be afraid to try new things," replied the executive. "The best way to find out what you like or don't like is by testing. Your first time may certainly not be the best, but don't be afraid to try again."

When they had finished the ice cream, Chuuya paid the bill and they left the premises.

"Listen," he told them before leaving. "I hope it wasn't too awkward for you. However, when I was your age, I would have liked someone to have discussed this issue with me, to save me several bad experiences. I really hope that what I told you will serve you in the future."

Atsushi and Akutagawa looked at each other and smiled.

"Thank you for talking about this with us, Chuuya-san," the albino thanked. "Knowing about these things never hurts, and it's better to know them from you than from Dazai-san" He shuddered.

"Yes," agreed the black-haired. "Thank you for giving us your support."

"It doesn't matter. Do me a favor and last a long time together. You two make a beautiful couple."

Unable to contain himself, Nakajima rushed towards the ginger and gave him a hug. Chuuya was surprised, but reciprocated, even extending a hand to Akutagawa for a hug as well.

"Take care of yourself, Chuuya-san." They said goodbye when they separated.

"Same, Atsushi. See you tomorrow, Ryuūnosuke."

Once the young men were out of sight, the redhead turned around. He was going to visit his own boyfriend.
