A few days had passed since that midnight encounter on the family dining table, but the heat between Zenith and Mike had only grown sweeter and more insistent.
The house had settled back into its familiar rhythm—Paul leaving at dawn for patrols, Rudeus practicing in the yard with his light brown hair bouncing, Lilia moving through chores with quiet efficiency.
Yet every time Zenith passed the dining table or the hallway outside the master bedroom, a warm little thrill bloomed low in her belly. She no longer fought it. She welcomed it.
Tonight, she had made her choice with eager clarity.
Paul had come home exhausted and fallen into a deep, snoring sleep the moment his head touched the pillow.
Rudeus was long gone to dreamland. The house was silent except for the soft rustle of night insects outside.
Zenith slipped out of bed wearing only her thin white nightgown, the fabric whispering against her skin as she padded barefoot into the hallway.
She left the bedroom door slightly ajar—deliberately—so the risk would feel even sharper.
Mike was already waiting, having crept in through the back door minutes earlier.
The moment she stepped into the hallway, she reached for him, pulling him close with a soft, eager smile.
"Mike," she whispered, voice warm and breathy with excitement, "he's sleeping right there. I want you to fuck me right outside our door… while he's on the other side."
Her blue eyes sparkled with pure, willing mischief.
No hesitation this time—just open, affectionate hunger.
She turned around, placed both hands flat on the bedroom door, and arched her back, pushing her ass out toward him.
The nightgown rode up on its own, baring her bare, already glistening pussy and the full curve of her ass.
Mike didn't need telling twice.
He stepped behind her, freed his thick, veined cock, and rubbed the broad head along her soaked folds.
"You're so fucking eager tonight," he growled low against her ear.
Zenith pushed back against him, rubbing her dripping slit along his length.
"Because I want it," she breathed, voice trembling with anticipation. "I want you to rail me right here… where Paul can almost hear every thrust."
He pushed in.
Zenith's mouth opened in a silent gasp of pure pleasure as his thick cock stretched her wide—every heavy inch forcing her walls apart until his hips met her ass and he was buried to the hilt.
The fullness made her toes curl against the floorboards.
She gripped the door tighter, knuckles whitening, biting her lower lip hard to keep any sound from escaping.
Mike started thrusting immediately—deep, powerful strokes that rocked her whole body forward.
The wet *PLAP-PLAP-PLAP* of skin slapping skin echoed dangerously loud in the quiet hallway, his heavy balls slapping rhythmically against her clit.
Zenith's heavy breasts bounced wildly inside the nightgown, nipples scraping the thin fabric with every brutal plunge.
She pushed back to meet him eagerly, rolling her hips, fucking herself onto his cock with the same loving enthusiasm she once saved only for Paul.
"Harder, Mike," she whispered, voice husky and eager. "Fuck me right outside his door… make me take every inch while he sleeps…"
Mike gripped her hips and gave her exactly what she wanted—relentless, pounding strokes that made the bedroom door rattle faintly in its frame.
The head of his cock kissed her cervix on every deep thrust, dragging along her g-spot on the way out.
Zenith's juices coated his dick and ran down her thighs in shiny trails, dripping onto the floorboards right outside the marital bedroom.
Inside, Paul's snoring continued uninterrupted.
Zenith held the door with both hands, bracing herself as Mike railed her from behind.
Her blonde ponytail swayed wildly with every impact, breasts jiggling heavily.
She was soaked—wet, filthy sounds filling the hallway as his thick cock plunged in and out of her greedy pussy.
Every thrust pushed a tiny, breathy whimper from her lips that she tried desperately to swallow.
Lilia watched everything from the shadowed corner at the end of the hallway.
She had heard the first soft rustle and crept out, unable to resist the pull.
Now she stood hidden in darkness, nightgown hiked to her waist, three fingers buried deep inside her dripping cunt, pumping in time with Mike's thrusts.
There was guilt, yes—but it was quieter now, softer, almost thrilling in its own way.
Mostly she felt a hot, shameless excitement at the sheer audacity of it.
'Right outside his door… while he sleeps… she's so eager for it…' Her thumb circled her clit frantically, eyes locked on the sight of Zenith bracing against the bedroom door, ass rippling with every powerful thrust, face flushed with open pleasure.
Neither Zenith nor Mike noticed her. They were too lost in each other.
Mike leaned over Zenith's back, one hand sliding around to rub tight circles on her swollen clit while the other reached up to squeeze her bouncing breast through the nightgown.
"You're dripping all over the floor," he growled quietly against her ear. "So fucking wet for me right outside your husband's room."
Zenith pushed back harder, riding his cock with eager rolls of her hips. "Because it feels so good… I love this… I love feeling you while he's right there…"
She came suddenly—hard and silent—walls clamping down around his thick cock like a vice, a fresh gush of hot juices squirting around his shaft and splashing onto the floor.
Her entire body shook, legs trembling, hands gripping the door so tightly her knuckles turned white. She bit her own arm to stay quiet, eyes fluttering in ecstasy.
Mike kept pounding through her orgasm, the wet *PLAP-PLAP-PLAP* growing even louder.
When he felt his own release building, he groaned low against her neck. "Zenith… I'm close…"
She turned her head just enough to meet his eyes, voice eager and trembling with pleasure. "Inside me… cum inside me, Mike. Fill me up right here… I want to feel it leaking out while I sleep next to him."
The words pushed him over the edge. He slammed in deep one final time and let go.
Thick, hot ropes of cum erupted straight into her womb—pulse after powerful pulse, flooding her completely.
Zenith moaned softly into her own arm as she felt every spurt, every throb, the warm rush spreading deep inside her.
She came again from the sensation alone, walls milking him greedily, drawing out every last drop.
They stayed locked together for a long moment—Mike still buried inside her, cum slowly leaking around his cock and dripping down her thighs onto the floor right outside the bedroom door.
Zenith's breathing was ragged, but her face wore a soft, satisfied smile. She reached back to stroke his thigh affectionately.
Mike finally pulled out with a wet *pop*. A thick glob of his cum immediately oozed from her well-fucked pussy and ran down her leg.
Zenith turned, dropped gracefully to her knees, and cleaned his cock with loving, gentle sucks and licks until he was spotless.
They shared one last tender kiss. Mike slipped out the back door into the night.
Zenith quietly opened the bedroom door, slid back into bed beside her sleeping husband, and closed her eyes, the warmth of another man's cum still deep inside her.
Lilia remained hidden in the shadows a moment longer, fingers still moving slowly inside herself, body trembling with aftershocks and quiet, shameless excitement.
She had watched everything.
And deep down, she already knew she would be back to watch again.

'Three weeks later'
The morning sun streamed through the kitchen windows as the family sat at the same dining table where so many secret sins had taken place.
Paul was laughing at something Rudeus had said, messy brown hair still sleep-tousled.
Lilia served breakfast with her usual quiet grace, though her light brown hair seemed a little more tightly pinned than usual.
Zenith stood at the head of the table, hands folded gently over her lower belly, a soft, radiant smile on her face.
"I have wonderful news," she said in that warm, airy voice they all loved. "I'm pregnant."
Paul's spoon clattered onto the table. His face lit up with pure, boyish joy.
He shot to his feet, scooped Zenith into his arms, and spun her around laughing.
"Another one! Gods, Zenith—another baby! I'm going to be a father again!" He kissed her deeply, eyes shining with happy tears. "We did it, love. We're having another Greyrat!"
Rudeus cheered, light brown hair bouncing as he clapped. "I'm going to be a big brother!"
Lilia stood by the stove, a plate trembling slightly in her hands.
She met Zenith's eyes for the briefest second. In that glance, everything passed between them unspoken.
Lilia knew.
She knew the child growing inside Zenith was not Paul's. She knew exactly whose seed had taken root that night right outside the bedroom door.
Yet instead of crushing guilt, a strange, complicated warmth bloomed in her chest—part lingering shame, part undeniable thrill at the secret they now shared.
Zenith simply smiled that same gentle, motherly smile at her husband, one hand resting protectively over the small life growing inside her.
The game had become something far more permanent.

End of Zenith's corruption.
Next Vol is going to be Lilia's Punishment.
Funny thing, this is the true first fanfic I've ended (Since I could end this right here). The irony of the first story I personally ended is a smut, not to mention an NTR.
Anyway, I'm going to stockpile some of Lilia's episodes first before uploading it.
