Raiden clenched his molars and wrapped his large hand around the back of Rihana’s head. 

If he continued like this, he felt he might press down on the back of her head like a madman, so he gathered what remained of his reason to stop her movements. The unfamiliar f*llatio was stimulating enough to make his eyes roll back.

When her back-and-forth head movements were stopped by his hand, Rihana looked up at him with a puzzled expression while still holding his member in her mouth. That sight was also intensely arousing, making his p*nis swell larger inside her mouth.

“Let’s stop this.”

His voice, struggling to contain his excitement to an obvious degree, didn’t sound like someone who wanted to stop at all. So Rihana asked why while still holding the member in her mouth. The member filling her mouth twitched and swelled larger once again.

“Take it out, take it out.”

Raiden urgently pushed Rihana’s forehead away.

“Was it… not good?”

Suddenly restrained and displeased, Rihana sat up and asked carefully. This seemed like trying to excite someone to death.

“It’s because I’m not used to it. If we keep going…”

“No, so just don’t say anything for a moment, Hana.”

Raiden looked pained, covering his face with one hand while holding the other toward her. 

Thinking he might be in a bad mood because she was clumsy, she looked down, but seeing the p*nis that kept twitching and leaking prec*m, it didn’t seem to be that, so she let out a sigh of relief.

“Don’t sigh, because it’s not that what you did wasn’t good.”

When Rihana sighed, Raiden, misunderstanding, muttered like that.

“Then why did you suddenly make me stop?”

“Because it’s dangerous.”

Raiden lowered the hand that had been covering his face and looked at Rihana.

“Dangerous…? What is?”

“If we continued, I would have lost my mind and handled you roughly.”

This was the same man who had worried like this even on the day he was in heat from the aftereffects of suppressants. When the act actually began, he had taken more care than ever to heighten her arousal, so she didn’t understand why he worried like this.

“You can handle me roughly.”

“That’s dangerous talk.”

“Did you forget? I’m the Empire’s greatest swordsman.”

“What does that have to do with this?”

“What do you mean what does it have to do with it? It means I’m that strong. I’ve been rolling around battlefields since I was young. Whether monsters or enemies, I’ve cut them down with my own hands, my own sword. Do you think something would happen to me just because you handle me roughly during s*x?”

Rihana spoke calmly while looking at Raiden with an absurdly expressionless face, causing his face to fill with bewilderment.

“Ha. You really have no fear.”

Raiden let out a deflated laugh and muttered to himself, then soon looked at Rihana with a serious expression. Feeling she shouldn’t avoid his gaze at his resolute expression, Rihana stared directly into his eyes.

“I might hurt my master. Do you think you could handle it if I shoved my c*ck into that small mouth and thrust my hips?”

“…”

“You’d cry and beg me to stop, wouldn’t you? Want to try? Want me to push you once?”

Whether she was a bit frightened by Raiden’s words, Rihana’s black eyes trembled faintly. Raiden continued speaking without taking his gaze off her.

“You’re not used to sucking c*ck. That’s why I’m trying to be considerate of my master.”

“…”

“You understand, right? So let’s stop this and get to it.”

“B-but you didn’t come.”

When Raiden tried to pull Rihana’s arm to lay her down on the bed, she pushed his hand away and leaned her upper body back slightly. Raiden’s eyes widened at her unexpected words and actions.

“I want to see you come. I want to see you come in my mouth.”

“…”

“It’s only the second time. So… ah, maybe it’s not just the second time for you.”

Another woman might have sucked you off. Rihana muttered to herself, then immediately rushed forward saying she needed to see him come in her mouth even more.

“You can handle me roughly. I’m not afraid of getting hurt. I’ve been hit by arrows and stabbed by swords. I’ve even had my shoulder bitten by a monster.”

As she grabbed Raiden’s p*nis with both hands again while speaking, he stared at her without saying anything.

“Come in my mouth. We can do the thrusting after that.”

Hah. A sigh close to a groan flowed from Raiden’s lips. Just how was this woman built to be so fearless? 

Since this was his first time being properly sucked like this, his habitual restraint and self-control would be rather useless. He could tell from how his hand had automatically grabbed the back of her head when he got excited for a moment. 

It was fortunate that he had pressed down his instincts as much as possible—if he had gotten just a bit more excited, he would have pressed down until her proud nose was crushed between his pubic hair.

She didn’t know about his efforts and wouldn’t bend her stubbornness. Her throat would probably bulge as his member was pushed in, making her cry with tears and snot, and maybe his excited hips wouldn’t be able to control themselves and thrust relentlessly, tearing the corners of that small mouth. 

Seeing her open that small mouth again to devour his member, insisting she had to see him come, he really felt he would only be led around by her.

But since he really didn’t want to make her cry or tear the corners of her mouth, he pushed away her head that kept approaching once more.

“No other woman has sucked me off, and you’re my first too, so calm down a bit.”

Rihana’s eyes widened.

“…Really?”

“It’s really true, so let go of my c*ck.”

“…”

“Ah. Don’t squeeze so tight. If my c*ck bursts, the one who’ll be sad is my master, right?”

“If it’s the first time, we should do it more. Why do you keep stopping me? Don’t tell me you don’t like that I’m your first? Is that why you’re acting like this?”

“Don’t misunderstand and calm your excitement for a moment, master. I’m your first and you’re my first, so why would I dislike it?”

“…Then why.”

“It’s better to stop at the right time when you’re not used to something yet. There’s no need to go all the way and see blood, making the next time frightening.”

“…”

“This is only my second time being sucked, so I’m extremely excited and can’t be considerate of you at all. So wait, please.”

“But another woman might suck yours…”

“Why would another woman suck mine? Does my c*ck have no autonomy? Ah, since I’m a slave, if some noble lady rushes to suck my c*ck, I naturally have to offer it?”

“…”

“Then you protect it. You’re my master, aren’t you? Why can’t you think of protecting my c*ck’s autonomy?”

“I’ll protect it, I will protect it…”

“Right. I trust you, master. So spread your legs a bit. I’ve been wanting to thrust so badly that my c*ck feels like it’ll burst, so please protect this c*ck first.”

“…”

Even at Raiden’s words, still unable to give up her desire to see him ej*culate in her mouth, Rihana pressed down on Raiden’s p*nis with both hands while hesitating.

“It’s yours, I swear. The only person who’ll be able to suck my c*ck and make me come for the rest of my life will be my master, so let’s stop for today and put it in.”

For the rest of my life. What was it about those words that made her heart pound? 

Although he was staying at her mansion at the Duchess’s request, he might be a man who wasn’t actually a slave. 

A man who might have to go back to the Duchess someday, or go somewhere else entirely. From such a man’s mouth came the words “for the rest of my life.” Hope and expectation sprouted from those single words.

“Can I… believe you?”

So the desire to turn that hope and expectation into certainty arose. At Rihana’s careful question, Raiden pulled up the corners of his mouth in a smile.

“Spread your legs first. I’ll make it so you can’t help but believe.”

* * *

Raiden, who had said he would make her unable to help but believe, ej*culated inside Rihana six times after that. 

She didn’t understand what relationship relentless thrusting s*x had with making someone unable to help but believe, but anyway, after accepting him until she had no strength left to move even a finger, it didn’t seem like he would easily disappear from her side.

Really finding it hard to move, Rihana lay collapsed face-down on the bed and moved only her eyes toward Raiden, who was personally receiving the basin and towel Mary had brought. She didn’t even have the energy left to turn her head.

Raiden, who had shaken and thrust so much on top of her, didn’t look tired at all. Rather, he looked strangely energetic. No, what looked strange was that p*nis that wouldn’t subside, brazenly asserting its presence inside the robe he was wearing. 

Raiden began wiping Rihana’s body with a towel dampened in the water Mary had brought, his lower body still fully er*ect.
