How to Become a Sadist’s Lover

Class

Surprisingly, Yan felt like he was falling for Sirius all over again.

“Did you really catch this one alone?” Dave asked again. Sirius remained completely silent. Yan stepped in on Sirius’s behalf.

“Dave, why do you keep asking someone who’s tired! It’s not like you haven’t seen how amazing Sirius is as a vampire hunter for a while now.”

What an incredible person I’m in love with! Keeping that thought to himself, Yan’s eyes sparkled.

It was almost unbelievable how perfect a person could be. Handsome, with the charm of being taciturn, and even saved the life of someone in trouble (Yan himself). On top of that, he was even extraordinarily capable!

Unlike typical vampire hunters who had appeared a month ago, his performance was exceptional. Even veterans who had been handling vampire-related cases for a long time were amazed by his skill at literally “hunting” vampires.

‘How can someone so perfect actually exist? Could it be that he’s not even human?’

Even to himself, it seemed like nonsensical thinking. That couldn’t be possible, right? Yan dismissed that fantasy with a giggle. Of course, he was completely unaware that he had inadvertently stumbled upon the truth.

“Sirius, I’m sorry for questioning you like an interrogation. It’s just so incredible. ‘Heavy Fog’ Emily is Rank A, isn’t she? How on earth did you manage to catch a Rank A vampire all by yourself?”

“Dave! If you’re curious, read the report later. Stop prying!”

“What’s the big deal? I can ask personally. Am I being rude, Mr. Sirius?”

Watching the two bicker, Sirius gave a cool smile. For him, this was an extremely dramatic change in expression. Yan stopped arguing with Dave and his face turned bright red.

“It’s thanks to the information I received. Wasn’t I able to know Emily’s movement routes because I participated in the police meeting?”

“But fighting vampires isn’t just about having information. Even if you knew her route, how did you win in a one-on-one fight?”

“That’s—”

Yan momentarily lost himself in Sirius’s face. It was because he was giving a sweet smile. Whether it was his imagination or not, Sirius seemed particularly expressive today. And again perhaps due to his mood, Sirius even seemed alluringly seductive today.

“—a trade secret.”

“…Pardon?”

Yan, who had been busy admiring Sirius’s face, was dumbfounded a beat late. Dave also gaped at the unexpected response.

“Given my profession, it’s difficult to explain.”

“Ah, yes. Trade, trade secret… I understand, Sirius.”

Dave scratched the back of his head while stumbling over his words. It seemed strange that it was such an unspeakable matter, but once he called it a trade secret, there wasn’t much to say. Come to think of it, asking a vampire hunter about combat methods might be as rude as asking a chef for their secret recipe.

Sirius asked, “Yan and Dave, you have a day off tomorrow, right?”

“Yes, that’s right.”

Dave responded with a hearty laugh. Who knows how long it had been since they’d had a break. Dave was very grateful for the rest that the captain had tossed their way, saying they’d worked hard all week. However, Yan looked glum beside him.

“Yan? Aren’t you happy about the vacation?”

“Well, I…”

It’s not like I have a lover to enjoy the vacation with, you know. Yan kept those words hidden in his throat.

Of course, there’s no rule that says you must spend your vacation with a lover. Still, Yan wasn’t entirely happy about this vacation.

‘So today is the last day I’ll be going around with Sirius.’

It had been busy for a week, but he was happy to be able to stick with him the whole time. He hadn’t been much help in catching Emily, and he also hadn’t been able to help Sirius as he had secretly hoped. Nevertheless, the past week had been like a treasure to Yan.

“Oh, Yan.”

A box suddenly appeared in front of Yan, who was secretly feeling down.

“What’s this, Sirius?”

“I received it in front of the police station. Someone asked me to deliver it to you.”

“What? Who?”

“Some man.”

“…By any chance, was this man blond with blue eyes? Tall like a model, or rather, a bit more muscular than a model? Like a movie star…”

Hey, what fairy tale prince are you talking about? Dave mocked from the side, but in reality, Procion’s image did resemble that description. Of course, if he were to actually appear in a story, it would need an “Adults Only” label, so it definitely wouldn’t be a fairy tale.

“Yes, he looked like that.”

Sirius nodded.

That meant the person who had left this box was Procion. Since Procion knew both him and Sirius, it wasn’t strange that he had found him near the police station.

“Thanks for delivering it, Sirius.”

“No problem. Oh! Yan.”

“Yes?”

“That man said you should open the box immediately upon receiving it.”

“Is that so?”

If I’m told to open it, I will. Yan took out a cutter knife without much thought. Then Sirius relayed more of Procion’s message.

“Also, he said it would be better to open it in a place where no one else is around.”

“…I-is that so?”

Yan cleared his throat unnecessarily and secured the box. Somehow, he seemed to have an idea of what might be inside. If what he was thinking was correct, it wouldn’t be good to open the box in front of others.

“Sirius, I’ll be back in a moment. Just going to the restroom.”

“Sure.”

As Yan walked away with the box tucked under his arm, Dave called out to him.

“Yan! Be back before the briefing starts!”

Without even acknowledging the reminder, Yan headed straight for the bathroom. He was too curious about what might be in this box—surely some adult items—to pay attention to anything else.

That’s why Yan didn’t notice. The fact that Sirius slightly furrowed his brows while watching him walk away.

***

The bathroom was completely empty. Yan entered the furthest stall and locked the door. Perhaps because he felt safe in a place where no one was around, his mind became strangely at ease.

“…Ah.”

However, the moment he opened the box and saw its contents, Yan became uncomfortable again.

It was clear why he was told to open the box where no one was around. As soon as he opened it, a vibrator was visible.

“What’s this? A rubber band? Looks stretchy.”

The vibrator wasn’t particularly surprising, but the object placed next to it was something he couldn’t identify.

It was a set of three rings attached in a row. Due to the soft silicone material, it looked like a hair tie at first glance.

“My hair isn’t long enough to tie up, and I don’t think I’m supposed to wear it on my fingers…”

Yan slipped the rings onto his fingers and twirled them around while deep in thought. The only place it seemed they could go was on his fingers, but the size was too large for that.

“Oh? A letter.”

Suddenly, the bottom of the box became visible. There was an envelope he hadn’t noticed before. Yan put down the unidentified object and opened the envelope.

“Dear Yan,

This is today’s homework for you, who has neither a fully opened hole nor patience.

Insert the vibrator in your back, then insert the plug. Tie up that cute thing of yours with the rings.

Stay in that condition throughout work, then come straight to the hotel after you finish.

Not a single drop of milk should be spilled until then.

Remember, Yan.

Don’t cum until I give you permission.”

“…”

The letter ended there. The next page contained detailed instructions for using the items.

Procion’s handwriting was extremely elegant, but Yan’s face grew increasingly pale as he read through it.

“What is this?!”

After reading the attached instructions, he already felt his strength draining away. The fact that such an obscene object existed in this world was almost impressively conceived.

The place to wear the three rings was none other than his dick. Like tying hair with a rubber band, it was meant to bind his testicles and dick.

“T-this… like this?”

Yan clumsily followed the instructions. Fortunately, detailed illustrative examples were attached, so he didn’t have to fumble much. To begin with, the method of wearing it wasn’t that complicated.

The problem, however, was the psychological barrier. Do I have to do this? Do I really have to do this? Yan murmured with a tearful expression, but soon he made up his mind and let out a long breath.

“Alright. It’s not that difficult, right?”

The vibrator was a cute size. Although it felt weird to have something like this inside him at work, it didn’t seem like it would be burdensome for daily activities. The same went for the silicone rings. It seemed like his dick would be somewhat constricted, but since he wasn’t erect, it shouldn’t be too uncomfortable.

As Yan pushed the vibrator in, he responded to the phrase “Don’t cum until I give you permission.”
