Flashback...
"Those darkened nipples suit you beautifully, Grayfia... a mark of your pregnancy."
"Thank you very much. To receive such a gift from my Master... I'm truly honored."
The silver-haired beauty, Grayfia, had her chest fully exposed, her generous breasts proudly on display.
They were alone in Takashi Mitarai's private chamber—no prying eyes, no interruptions. Her posture subtly emphasized her breasts for his enjoyment.
The tips of her full breasts had changed drastically from the pregnancy. What were once soft pink nipples now bore a mature, deeply erotic black hue, reflecting the transformation from pure maiden to a fertile, submissive woman. Just five months ago, they still held the innocent tint of virginity.
Dangling from those darkened nipples were silver ring piercings—matching her hair color—gifts from Mitarai himself.
They swayed with every movement, asserting their presence even beneath clothing.
To Grayfia, they were more than mere ornaments—they were proof of her devotion as his maid, and her place as his personal woman.
"Your belly's gotten bigger~! Looks like our child will be born soon, huh?"
Grayfia's stomach was unmistakably swollen—her due date was only days away.
Coincidentally, she and Venelana, who had conceived slightly before her, were scheduled to give birth around the same time.
Mitarai still remembered how overjoyed Venelana had been about that.
Unlike humans, devils were incredibly durable. Even with a belly stretched to its limits, Grayfia's body remained capable of handling sex without endangering mother or child.
Devils had evolved strong reproductive bodies due to their dwindling numbers, and even though Grayfia was born before the decline, she had matured to become no different than the newer generation of fertile devil women like Rias.
Mitarai gently caressed Grayfia's swollen belly, letting his thoughts wander to the daughter growing inside her.
Both Venelana and Grayfia were carrying daughters, daughters they had already pledged to him.
Even Mitarai had been left speechless when they offered up their future children for his use. He hadn't even had the chance to object before they decided it.
Incidentally: Devil children inherit their mother's race—so a child born from a devil woman will always be a devil.
"Even now, Master... this filthy, aching pussy of mine craves your affection... It's already soaked and ready for you."
Grayfia spread her legs wide, lifting her maid skirt, her voice dripping with heat. Her usual calm expression shattered into the face of a needy, aroused wife. She made no attempt to hide it.
Mitarai, unable to resist her desperate temptation, immediately stripped off his pants, his cock springing free.
The room was instantly filled with the raw, animalistic scent of arousal. Compared to when Grayfia first saw it, his manhood had become larger, thicker, undeniably that of a superior male.
The heavy musk assaulted her senses, nearly making her dizzy, but she obediently opened her thighs further, yearning to be filled.
As a maid, Grayfia usually held back, unlike the more lustful harem members like Rias.
She maintained a posture of submission, awaiting her Master's will rather than pouncing on him like a beast in heat.
But even her iron discipline couldn't restrain the hunger boiling within. Her instincts as a female devil often overpowered her rationality, leaving her shamelessly spreading her pussy open, like now.
Her soaked, devilish cunt gleamed under the room's light, glistening with a thick coat of love juice.
The inner lips had matured into the folds of a true MILF, a transformation no one knew except Mitarai.
Like her nipples, her folds had darkened slightly—but inside, she was still a tight, expert sheath that gripped and milked Mitarai's cock to the very limit.
A wet, obscene ~slurp, squelch~ echoed through the room as Mitarai's thick cock slowly pushed past the slick folds of Grayfia's drenched pussy.
From the tip of the glans to the full length of his shaft, he was swallowed whole by her eager cunt. Her body, primed for childbirth, showed no resistance—her tight, hungry hole accepted even his thick girth without hesitation, guiding him all the way to her deepest point: the entrance to her womb.
Every fold inside her clung tightly to his dick—rubbing along the sensitive ridge of his cockhead, caressing the thick veins on his shaft. The pleasure was overwhelming for both of them. Groans and gasps slipped freely from their lips.
"Master's cock~! It's so big ~ ahh, I can feel it lifting the womb that's carrying your baby... I'm so happy~!!!"
Grayfia looked up at Mitarai with a gaze filled with rapture, her expression a mix of a devoted woman and a wife overwhelmed by carnal delight.
Still connected, with his cock buried deep inside her, the two of them gently shifted from standing to the futon, mindful of the life growing inside her.
As satisfying as standing sex was, Mitarai wasn't about to risk putting unnecessary strain on her pregnant body.
Bathed in soft light, Grayfia's body was a sight to behold.
Her voluptuous breasts, swollen from pregnancy and heavy with milk, jiggled slightly with every breath. Her darkened nipples and large areolas made her look even more lewd, and the silver piercings running through each nipple only amplified her erotic appeal.
Whether from the stimulation or her own excitement, small beads of milky fluid were already dripping from her tits, filling the air with a sweet, decadent scent.
Just below, her pregnant belly stood out—pale skin stretched tight, with faint blue veins running beneath the surface, radiating an almost unholy kind of beauty. Despite being visibly full with child, her body was still irresistibly alluring.
Etched into her skin just above her groin was a glowing, violet crest—a magical slave mark. With a single touch, Mitarai could trigger her heat, no matter the time or place.
It was the ultimate symbol of ownership. It marked her not just as his maid... but as his sex salve.
And under that... her soaked, needy pussy was still in the middle of swallowing his cock.
Spread wide and glistening with slick juices, her lower lips had bloomed open like the petals of a forbidden flower. It looked almost like an abalone, the kind often used in vulgar comparisons—but with her maturity and the fact that she's a MILF, the resemblance was shockingly accurate.
The once-hidden inner folds now peeked out in full view, lewd and inviting.
Takashi began to move his hips slowly, carefully avoiding any sharp pressure on her belly.
"Nnngh master… your cock… It's moving… Ahh right there~!! Don't tease me so much…"
He knew her weakness—just behind her navel, the textured front wall of her pussy.
As soon as his thick tip rubbed against it, her body trembled and her moans poured out like honey.
