She had said it simply wanting to give him some kind of reward. In truth, she hated the thought of this thick, imposing member entering the mouths of women other than herself. 

If she hadn’t seen Raiden’s jewel-like blue eyes tremble dangerously at her words, she wouldn’t have realized what tremendous thing she had just said.

“Hah. You’re really going to cause trouble.”

Raiden muttered while letting out a moan-like sigh.

“Do you know what that means when you say it?”

Huh? With this pretty mouth? Raiden pressed his thumb firmly into Rihana’s mouth while muttering to himself.

“I know.”

Rihana answered without backing down. When she even lightly bit down on Raiden’s thumb that had entered her mouth, Raiden let out another moan-like sigh. Rihana found that sound very pleasant to hear.

“You don’t know anything, so what do you know?”

“I know. I’ve already done it before.”

Suddenly, Raiden grabbed Rihana’s wrist and quickly headed outside. Only when she realized his hurried steps were heading toward her bedroom did Rihana’s bewildered expression change to one mixed with excitement and tension.

Whatever happened, she hoped it would all be hers alone.

Of course, thinking of his surprisingly skillful s*x, she knew she wouldn’t be his only woman. 

Even if he hadn’t been a bedroom slave, he had been the Duchess’s slave, so with this body and this face, he couldn’t have maintained his purity until now. Besides, he was definitely too good at it.

But from the moment she took charge of him, she hoped he would know only her completely. It was an inconsistent thought, but that was how she felt anyway. 

Since situations might arise where the Princess or other women could bite, suck, and lick Raiden’s body, she wanted him to think only of her for everything beyond biting, sucking, and licking—even the moment of climax.

As Rihana walked toward her bedroom with her wrist held by Raiden, she recalled the methods for good f*llatio written in the er*tic book Letia had once sent her.

* * *

The beginning was quite bold, but when she actually saw Raiden sitting with his firmly er*ect p*nis exposed, she began to feel a little scared. 

This was due to a vague fear of an act she still couldn’t get used to despite having done it before, and worried doubts about whether that large member could fit in her mouth.

Since she had spoken the words herself, she couldn’t take them back now, and even if she could, she couldn’t pretend not to see the aroused p*nis that kept leaking prec*m. 

Rihana swallowed her dry saliva and positioned herself between Raiden’s legs, which he had kindly spread for her.

When she hesitated and wavered a bit, Raiden chuckled lowly and asked if she was getting scared now. Rihana shook her head vigorously, saying no. 

After glancing at the panting member of Raiden, who was leaning back against the headboard unable to hide his excitement, she carefully reached out and grasped it. 

The member looked thicker than her forearm, so it was impossible to hold with one hand, naturally requiring both hands.

“Don’t bite. If you break my c*ck, you’ll be the one who’s sad.”

She shot him a look at his playful words. She knew he was deliberately acting this way to ease her tension after noticing how nervous she was, and while she didn’t particularly dislike it, she felt she should make an appropriate gesture. 

Anyway, she was currently in a very, very excited state, more nervous than she had been during her engagement to Casian, which had been the most nervous moment of her life until now.

Rihana carefully stuck out her tongue and licked the indented part of the tip with a small lick. The clear prec*m seemed to taste slightly salty, or maybe it had no taste at all. 

Her heart was beating so hard with each breath that it seemed like it might burst out through her nostrils, making her think she might have temporarily lost her sense of taste.

Gathering some courage, she opened her mouth wide and took the gl*ns in her mouth, causing an adorable moan she had never heard before to flow from Raiden’s lips. The husky, cracked, languid tone was far from cute, yet strangely adorable.

Even with just the gl*ns inserted, Rihana clenched her jaw tightly around the member that filled her mouth. 

The p*nis flinched in response, making her tongue move as well. She licked in circles along the smooth, round gl*ns, then tapped and licked under the corona with the tip of her tongue.

Wanting to take more in her mouth, she lowered her head, but the volume of the member filling her mouth made her shed tears after only a short time. Unable to help it, she couldn’t even insert half of it, so she swirled her tongue around the member and pursed her lips to suck with slurping sounds.

She hadn’t done much, but her jaw already hurt. Unable to bear it, she pulled her neck back and withdrew the p*nis that had filled her mouth. Saliva formed a long thread that stretched out before snapping with a pop.

“Is it hard?”

When Raiden asked while wiping the saliva from Rihana’s lips with his thumb, Rihana shook her head and stuck out her tongue to lick the veined shaft like she was rubbing it. Given its thickness, licking it this way was a bit more comfortable for her than putting it in her mouth. 

But Raiden’s face definitely showed more excitement when she put it in her mouth than when she licked it like this.

Although her jaw still hurt a bit, Rihana endured it and opened her mouth wide to swallow the member as much as possible. When she pushed it in until it touched her throat, tears reflexively streamed down. 

With her eyes squeezed shut, she slowly moved her head, feeling the member inside her mouth grow even larger. Just how much bigger was this thing going to get? 

It was a p*nis she had embraced with her own body, yet it suddenly felt strange and frightening.

She instinctively became wet below at the continuously flowing lewd sounds. Using her palate and tongue, she constantly stimulated the gl*ns area and sucked down the prec*m. 

For some reason, her jaw hurt more and more, but her f*llatio also became increasingly skillful, so Rihana eagerly moved her head and deliciously consumed his p*nis.

With her face buried between his thick thighs, she repeatedly inserted and withdrew the overwhelmingly large member in her mouth. It was truly endlessly overwhelming, but she couldn’t stop because of Raiden, whose face showed increasing excitement as her head movements quickened. 

His face looking down at her while savoring the pleasure with his mouth tightly closed was excessively s*xy and beautiful. Even when her jaw felt like it might dislocate, seeing that expression made her head move automatically.

Lewd sounds she couldn’t even imagine coming from her own mouth echoed throughout the room.

She flattened her tongue and swept down the shaft with each head movement. This seemed to give him unbearable pleasure, as Raiden’s member swelled even larger each time. She became curious about just how much the member could swell, as it kept growing inside her mouth.

Suddenly, a moan she had never heard before burst from Raiden’s lips. It was a sound that mixed something like suffering with low bass tones, scratchy yet adorable. Rihana’s eyes widened at his moan as she looked up at Raiden’s face. 

The moan that seemed unsuitable yet very suitable made Rihana’s lower abdomen tingle mercilessly. A man’s moan could be this lovely.

Lovely. That single word seemed to act like some kind of stimulant, as something gushed down from below. In bewilderment, tingling, and unbearable l*st, Rihana unconsciously tensed her lower abdomen and tightened around Raiden’s member filling her mouth.

Raiden’s Adam’s apple bobbed greatly as he looked down at her. His usually clear blue eyes had changed to the color of the deep ocean as he gazed at her. Unsuited to his languidly lowered eyes, his gaze at her burned frighteningly.

Eyes on the verge of losing reason, swept away by desire. That was exactly the kind of look.

It couldn’t be helped. The sight of a woman who was always pure and seemingly aloof without makeup, now with thoroughly wet eyes and flushed cheeks, holding his p*nis fully in her mouth, naturally aroused an unbearable sense of conquest and transgression. 

Moreover, hadn’t she said she would suck him off herself when he hadn’t even opened his mouth? The reason he had been holding onto seemed to have half-flown away at that moment.

She was innocent yet strangely er*tic in odd ways. Was it her personality of not being able to resist curiosity, or her innate competitive spirit? 

Either way, he had a premonition that he would never be able to match this woman in the future.
