The villa stood on a clearing in the mountains, by the shore of a lake that mirrored the blue sky.
A solid two-story wooden house, quietly waiting for its next guests. Because attendants came regularly to maintain it, the wide grounds that served as its garden were orderly and clean, not overgrown or neglected.
One female devil had just arrived at that lakeside retreat.
Her name was Grayfia Lucifuge.
A servant of the prestigious Gremory clan, the Underworld noble house that owned this villa as a vacation home. Having transferred in via the magic circle in one of the rooms, she straightened her familiar maid uniform and began to walk in composed silence.
The reason Grayfia had come here was to prepare to receive Rias Gremory, the Gremory heiress who would be spending time at the villa training in the mountains from today onward.
—or at least, that would have been the official story.
In truth, she was here because of an order from the other master she had been forced to serve, separate from the Gremory family.
Riser Phenex.
Their master–servant relationship was not yet even a month old, but she had already drunk deeply of the bitterness he dealt out.
When her beloved son Milicas fell ill, Grayfia had paid the price for Riser's "treatment." In exchange for the special Phenex Tears he provided—a rare, precious item that had saved Milicas from death—she had been taken into the Phenex estate as the instructor for a batch of new maids.
What she'd been told beforehand and what she actually found there did not match.
Her supposed job as "instructor" amounted to little more than serving as her new master's personal sex relief. On the very day she entered his service, Riser had demanded her body, and Grayfia had yielded.
For days, she'd been shut in his bedroom and used for breeding sex. Forced kisses, her breasts licked and tasted down to the last inch, nipples sucked raw, her womb flooded over and over with obscene quantities of semen no ordinary man could hope to match.
Grayfia had showed a rebellious attitude, but she had not resisted in action.
After all, this man was still the benefactor who had saved her son. Without the special Phenex Tears he had given them, Milicas might already have drawn his last breath.
With that thought locked in her heart, Grayfia endured.
I have to resolve the problem with Riser by myself.
That was the idea that rose naturally in her mind, even before thoughts of escape or fight. And so Grayfia began her life as Riser's maid.
A monster who had used some unknown, suspicious power to brainwash his own family, fucking his mother as a woman and getting her pregnant. A man who had laid hands on his own little sister as well.
To protect her most precious family from those claws.
To someday sever her relationship with him and return to them. She clung to that hope.
Sometimes her anger flared out, but outwardly she received him in a businesslike way. With her mouth, her pussy, her womb.
She let herself be covered inside and out in thick, suffocatingly male-smelling cum—so intense that it seemed she might forget the taste of her own husband.
Someday. No matter how many times her womb was packed full of his seed, that wish never faded.
Leaving the room, Grayfia headed straight for the entrance and stepped outside.
Confirming that no one was around, she walked into the forest that encircled the villa.
"Riser-sama."
Hiding her body behind one of the trees, she called her master.
Moments later, a man appeared at her back—despite the fact that no one had been there.
A tall figure in a red suit, with slightly long blond hair. His face was handsome, but marred by a sleazy, ugly smirk that betrayed his rotten personality.
As if it were the most natural thing in the world, the man reached out and wrapped his arms around Grayfia from behind, grabbing her breasts.
Riser's fingers sank into her breasts through her underwear and maid uniform. The same selfish, inconsiderate embrace as always — treating her body purely as something to be used. Of course he'd think of women as convenient tools.
Feeling the bulge at his crotch press against her ass made her stomach twist with disgust, but she kept up the conversation.
"Is this location acceptable, my lord?"
As instructed beforehand, she had come out into the forest and taken him to a spot where the villa could be seen, then called him. And, as always, he had appeared beside her via that same unknown power and immediately begun his rude groping. She could do nothing but accept it.
"Yeah. This'll do."
Riser murmured at her ear.
Because he had whispered in that same spot countless times in bed, Grayfia's body shivered automatically now. To her chagrin, it felt like he was steadily contaminating her body. Despite herself, her nerves tingled with unwanted sexual stimulus. A creeping sensation ran down her spine, and little by little, heat pooled low in her belly.
"Been a while since I've had sex outdoors. Let's enjoy it. Go on—show me how you beg for it."
He lifted his hands from her chest and straightened up. She heard the sound of a zipper opening, and then the thick head of his cock pushed up against her ass.
Far bigger than her husband's, the quality and sheer volume of its cum on a completely different level. The sight of it the first time had filled her with simple fear, and today again it demanded Grayfia's body.
Never gets tired of this, does he…
Biting down on the urge to spit that out, Grayfia braced one hand on the tree trunk, stared straight ahead, hiked up her skirt, and pushed her ass back.
Then she invited him with a lewd gesture she'd never shown even to her husband.
"Please… go ahead…"
After a few seconds of her slowly shaking her hips, Riser and Grayfia became one.
He pushed her purple panties aside and slammed his cock into her with a wet shlup.
The flared rim of his shaft scraped her inner walls on the way in, then stopped only when the tip smashed a deep, heavy kiss against her cervix.
Grayfia endured.
Endured the urge to cry out at that violent shock. If she made a sound, she'd only make him happy. She hated nothing more than the way he smiled when he watched her body react, when he saw her feel pleasure from his roughness.
"…Haa…"
Riser exhaled happily, like he'd just sunk into a hot bath after being chilled to the bone.
His hands slid over her ass for a moment, then began to rock his hips forward and back.
Above them, lush green branches reached upward, blocking out the pure blue sky. Trees rose in all directions, forming a small forest of their own.
Nature. Breathe, and clean, fresh air filled your lungs. Listen, and you could hear birds calling somewhere in the distance.
Even such a pleasant setting could be twisted this much, depending on who you were with.
Complaints murmured only in her heart, Grayfia accepted the cock sliding back and forth in her.
She wanted to get this over with as quickly as possible. Before Riser could come up with any more wicked schemes.
"I get that you're worried about Rias and the others, but don't get so worked up."
He hit the bullseye, and her heart skipped.
His instincts were irritatingly sharp in the worst places.
Not wanting to give him more to pry at, Grayfia forcibly discarded extra thoughts and let herself drift with the moment.
Wet shluck, shluck noises sounded as his cock played with her pussy.
While the pre-cum made her insides slick, she saw movement beyond the tree and the villa's front yard: a group of youths with luggage arriving.
Rias, the young devil heiress and current high school student, and her servants, all around the same age.
She could hear the surprised voice of Hyoudou Issei, the boy who had only recently been reborn as a devil, carried on the mountain breeze.
"Relaxed bunch, aren't they? Think they're actually planning to beat me?"
Riser muttered as he kept pumping into her. Grayfia didn't agree with the sneer itself, but she did share the assessment.
Issei, so newly turned from a human into a devil, lacked a sense of tension. If he planned to stay by Rias's side, he needed to calm down, grow up—
"…ah—…"
A sudden, sharper thrust mixed into the steady rhythm.
Caught off guard, she let out a small sound. Her pussy clenched down involuntarily, and that reaction seemed to amuse Riser.
His faint chuckle made her heart ripple with irritation and shame.
So much for telling herself to stay composed; here she was, already falling apart. Pathetic.
"Come on. Let's watch their training session together."
And the main act was only just beginning.
In the center of the yard stood Kiba Yuuto and Hyoudou Issei, facing off. The girls watched as they took up their wooden swords and exchanged blows.
The match was one-sided. Issei was stuck on the defensive, with Kiba pressing the attack. When Issei occasionally switched to offense, his swings were wild and easy to read, and Kiba would immediately knock the weapon from his hands.
"Seriously, is that guy gonna be okay?"
Riser murmured. Issei was still brand new to being a devil; it was only natural he couldn't keep up with someone like Kiba, who'd been turned in childhood.
Besides, Grayfia had already arranged things with Riser so Rias could win the upcoming Rating Game. Issei's current lack of polish wasn't a problem — or so she judged.
Even so, she found herself wondering when Riser would use his "rights."
In exchange for granting Grayfia's request, Riser had gained the right to make her love him as a woman — two full weeks' worth of time.
He'd secured that much, yet showed no sign of cashing it in.
When would he use it?
She couldn't just ask him outright, so she glanced over her shoulder. As always, Riser was rubbing his cock through her pussy like it was his birthright, happily pumping away.
Does it really feel that good? Why does he want me this badly?
Watching the man so obsessed with her, Grayfia's gaze met his.
"What is it, Grayfia?"
There was a faint note of tenderness in his voice, as if he were cherishing her.
The kind of tone that could trick you into thinking, If I just go to him of my own will, maybe he really will make me happy.
If she let herself fall into him, maybe she could protect the people she wanted to protect…
Grayfia crushed that thought instantly.
That path was forbidden.
That would mean nothing less than surrendering to a man with unknown, terrifying power. What she truly wanted was to get everyone in her family back, with no one missing. To return to that warm circle as Sirzechs's wife and Milicas's mother.
She couldn't afford to lose.
"Nothing."
Curt, flat. She made herself into a boring woman who would never bend for him.
"I see."
Even so, the flame of desire in Riser's eyes didn't dim in the slightest.
If anything, his cock thickened inside her, pressing her deeper from within, his thrusts into her cervix growing faster. Her inner walls were stretched wide, and every rough stroke of their joined flesh made her knees want to buckle.
"Face forward. Watch them carefully."
Obeying his order, Grayfia looked at Rias and the others.
Issei, refusing to give up no matter how many times he lost, challenging Kiba over and over.
Kiba, serious yet calm, meeting him head-on.
Rias, Himejima Akeno, Toujou Koneko, and Asia Argento, watching over them, offering encouragement when needed.
Rias's future was bright. Surrounded by such talented, kind people, those young shoots would surely grow into something strong enough to support both her body and heart, even when she overreached.
For the sake of that future—for the proper growth of those tender buds—Grayfia quietly received Riser's genes in her womb.
"…nn—…"
His cock buried itself to the hilt and stopped, then convulsed, spewing heat.
In the blink of an eye, his seed flooded and occupied her uterus, coating it thickly. She imagined the slimy, stubbornly clinging filth sticking to her insides, so hard to scrape out even in the bath.
And then, the brutal little sperm swimming vigorously in that pool, rushing toward her egg.
The moment those images began to form in her head, she cut her thoughts off and lowered her gaze.
"That's the first shot. We've got a long way to go."
Riser barely spared a glance for Rias's training, concentrating instead on playing with Grayfia. Everything was going just as he wanted.
Unable to defy the road he'd laid out, she quietly exhaled her hot breath where he couldn't hear, while her womb held on to the devil's seed.
