Chapter 16: Grayfia's wish

His flesh rod, which had forcefully penetrated her vagina after swiftly sliding aside her purple underwear, scratched her vaginal walls with its glans as if it were natural, finally halting at the entrance of her cervix after giving it a passionate kiss.

Grayfia endured it. She had to make sure not to let out a voice from the strong stimulation. If she made a sound, it would please Riser. Not only did she dislike herself for being aroused by his rough actions, she also couldn't stand Riser's smiling face as he watched her like that.

"Phew..."

Riser loosened his expression and let out a sigh, as if he had soaked his cold body in a warm bath. Although he briefly placed his hand on Grayfia's buttocks and caressed her, he slowly began to sway his hips back and forth.

Lush green branches and leaves stretched out to obstruct the piercing blue sky. Surrounded by trees bearing those branches and leaves, it was nature itself. If you took a breath, the clear air would fill your lungs, and if you listened carefully, you could hear the chirping of birds coming from somewhere.

Even such a pleasant environment could be tainted by the presence of the person you're with.

While expressing her dissatisfaction internally, Grayfia accepted Riser's flesh rod moving back and forth. She had to release Riser's desires as quickly as possible. Before Riser could think of any more devious plans, she had to do it quickly.

"It's understandable that you're worried about Rias and the others, but don't be in such a hurry."

Struck by the truth, her heart pounded.

This man has a strange sense of intuition. In order to prevent him from discovering any unnecessary pain while probing her abdomen, Grayfia abandoned futile thoughts and surrendered to the flow of the situation.

Squelch, squelch. The flesh rod frolicked with the vaginal flesh. As her lubricated vagina accepted Riser, Grayfia noticed that a boy and a girl carrying luggage had arrived at the front of the mansion, visible beyond the trees.

It was Rias, a female devil who was still a high school student, and her fellow servants of the same age. The surprised voice of a boy named Issei Hyoudou, who had recently become a servant, could be heard carried by the wind.

"They're so carefree. Do they even have the intention of defeating me?"

Riser spoke as he continued to move his hips diligently. While Grayfia didn't agree with him, she also held a similar opinion. She felt that the recently transformed Issei, who had just become a devil from a human, lacked a certain sense of tension. If she wanted to continue to be by Rias's side in the future, she hoped he would calm down a bit more.

"Ahh..."

A sudden forceful thrust mixed with the continuous movement. Surprised, she let out a voice. It seemed that the change in her tightened vagina had transmitted to Riser. Grayfia's heart was disturbed by Riser's faint laughter. She thought she should remain composed, but she was acting just like this. Truly pathetic.

"Now, shall we observe Rias and the others' training together?"

Even though their intimate moment was about to begin in earnest.

In the center of the garden, Yuuto Kiba and Issei Hyoudou faced each other, each holding a wooden sword. They swung their wooden swords while being watched by the male's member. The battle was leaning in Yuuto's favor, as Issei was constantly on the defensive. Although there were occasional shifts to the offensive, most of Issei's attacks were too heavy and easy to read, resulting in his wooden sword being knocked out of his hand by Yuuto immediately.

"Hey, hey, is that enough?"

Riser muttered to himself. It was only natural that Issei couldn't match Yuuto, who had transformed into a devil during his childhood. Also, Riser and Grayfia had already discussed that Rias would win in the upcoming rating game. It was not a problem that Issei was currently inexperienced, according to Grayfia's judgment.

However, Grayfia couldn't help but wonder when Riser would use that privilege. In exchange for granting Grayfia's wish, Riser obtained the right to make Grayfia love him. He had obtained the right for a period of two weeks, but there was no sign of him using it.

When will he use it? Unable to ask him directly, Grayfia turned her gaze backward. Riser, who was rubbing his flesh rod against Grayfia's vaginal walls as if it were a matter of course, was swaying his hips, seemingly enjoying himself.

Is it really that pleasurable? Why does he desire me to this extent? As she gazed at Riser, who displayed an extraordinary obsession with her, their eyes met.

"What's the matter, Grayfia?"

Riser's voice contained a slight hint of affection towards Grayfia. It gave her the illusion that if she approached Riser herself, he would make her happy. If she surrendered herself like this, perhaps she could protect those she wanted to protect.

But Grayfia immediately dismissed that thought.

That line of thinking was wrong. It would be no different from surrendering to Riser, who possessed an unknown power. What she should aim for is to regain their original life, with no one missing from their family. As Serafall and Milicas's mother, she should return to that warm circle.

She must not lose, under any circumstances.

"Oh, it's nothing."

She responded indifferently, making herself appear uninteresting and unyielding. Grayfia fully embraced that mindset.

"I see."

Despite that, the flames of desire in Riser's eyes did not waver, instead increasing the thickness of his flesh rod, as if pressing against her vaginal walls. The speed of his thrusts towards the entrance of her cervix increased. With each intense friction between their genitals, Grayfia felt like she would collapse from her knees.

"Face forward and observe them closely."

Following his command, Grayfia looked at Rias and the others. Issei, who continued to challenge Yuuto without giving up, even after repeated losses. Yuuto, who calmly and seriously confronted Issei. Rias, Koneko, Asia, and Akeno, who watched over them and occasionally offered words of encouragement.

Rias's future was bright. With such talented and kind-hearted individuals by her side, they would surely support Rias, who tended to go off track, both physically and emotionally.

Now, for the sake of that young bud's proper growth, Grayfia accepted the seed containing Riser's genes in her womb.

"Ah..."

Riser's flesh rod buried itself deep inside her vagina and stopped moving, releasing hot semen with a squelching sound. In an instant, it conquered her uterus, leaving behind a residue that proved difficult to remove during bathing. It was a sight of sticky fluid clinging to her uterus.

And within the semen, vicious sperm swam energetically. The thought of them vividly combining with the eggs almost crossed Grayfia's mind, causing her to stop her thoughts and bow her head.

"This is just the beginning. The road ahead is long, you know?"

Riser, who seemed more fixated on toying with Grayfia than showing much interest in Rias and the others' training. It seemed like things were going according to his plan, and Grayfia couldn't resist it. Frustrated by her inability to resist the flow of events, she secretly exhaled a hot breath that Riser couldn't hear.
