Introduction
I swallow hard, my eyes darting between his gaze and his lips as an intense wave of forbidden heat sears through me.
Dahlia Sterling has been engaged to her boyfriend, Sebastian Thorne, after five years of dating.
To the outside world, they seem like the perfect couple. And in many ways, they are. But behind closed doors, Dahlia's sex life with Sebastian is miserable and unfulfilling.
Despite countless counseling sessions and therapeutic efforts to fix the problem, nothing changes, especially since Sebastian constantly shames Dahlia for struggling with what he believes is a sex addiction.
Everything changes when Dahlia crosses paths with Sebastian's estranged older brother, Zane Thorne — a man who has secretly been in love with his brother's fiancée for years.
Zane once believed Dahlia was genuinely happy with Sebastian — That was the only thing that kept him from pursuing her initially. But the moment he realizes the truth, he makes it his mission to rescue her from her misery. By fucking her brains out and awakening emotions in her she can no longer ignore.
Now, she's caught between the Thorne brothers. One is her fiancé—her Mr. Sunshine, who could never love her the way she yearns to be loved. The other is his complete opposite—a man who would burn the world to the ground if it meant putting a smile on her face.

Chapter 1
DAHLIA
"Fuck, I'm close," my fiancé, Sebastian, grits out while still on top of me, his body carefully positioned between my legs as he thrusts in and out of me at a slow yet passionate pace—except I don't find anything about this sex... passionate.
If I'm being completely honest, this is purely boring sex.
Seb is too slow and gentle with me, and that isn't what my body craves. It's simply not how I enjoy being fucked.
But I can't voice my displeasure because I know my complaint will only upset him, like it always has the previous times I've told him I didn't enjoy the way he fucks me.
Heeding my therapist's advice, I once opened up to Sebastian and told him how I wanted him to be intimate with me in bed. How I wanted to be manhandled by him. Fucked ruthlessly until my legs started shaking uncontrollably. But apparently, those are absurd demands to him.
He once called me a slut for craving wild fantasies—for asking too much of him. When, in fact, all I wanted was for him to make me experience an orgasm for once. It's been ages since he last left me sated.
If anything, I always end up sexually frustrated after an intimate session between us.
I was hoping tonight would be different because we just celebrated his latest work achievement earlier this evening. The night was perfect, and the sexual tension was there. I was really looking forward to having one of the most pleasurable nights with him for the first time in a while.
"Urgh, fuck," Seb groans, pulling me from my thoughts as he suddenly increases his pace, his dick slamming in and out of me.
I feel my body ignite with sensation instantly, a rush of excitement surging through me.
Gosh, finally.
It's happening.
I think I'll finally have that orgasm I've been yearning for.
Unable to contain my excitement, I let my hands roam over his back, clinging to him as my trimmed nails dig into his skin. Soft gasps spill from my mouth, a tingling sensation trailing down my spine.
I moan quietly, inwardly grateful my wish for a wild night has finally come true.
However, it seems yet again, I am wrong.
Just three... three seconds later, a groan tears out of Sebastian's throat as he suddenly stops moving. He remains atop me, his dick still throbbing inside my core.
And that's when I realize.
He already climaxed—before me. Again.
The excitement I'd felt vanishes without a trace.
No. Fuck, no!
I wasn't even close to having an orgasm. How could he just stop?
Then again, it's not something I'm not already used to.
However, I can't let him leave me like this again. I'm so fucking horny right now, I could fuck a horse.
"Seb... Wait," I stop him as he pulls out of my desperately aching pussy.
"What is it?" he grunts, removing the condom from his cock without sparing me a glance.
Gosh, I feel like crying right now.
"You—I..." I struggle for words, my heart twisting painfully. I swallow hard when he finally looks my way.
I hope the disappointment on my face says everything I'm struggling to. But it's sad he doesn't catches on it.
"What's wrong with you?" he asks, his brows furrowed.
"I didn't orgasm, Seb," I say in a low voice, feeling deeply ashamed because I don't want to be labeled a whore again. "Please... can you continue?"
He shakes his head. "Can't, sorry." He sighs heavily before dropping onto the bed beside me. "Go watch porn or something, Dahlia. I'm tired. You know I've been working all day. I need to rest now."
"Please?" I beg as he turns his back on me, pulling the duvet over himself.
He sighs. "I love you, baby. But I can't. I'm really exhausted. Please try to understand."
For how long?
That's all I ever do—understand him. Every fucking time.
Is it impossible for him to make me orgasm just once?
For fuck's sake, I don't even remember what it feels like to be a woman anymore.
I remain on the bed for a moment, my resolve crumbling with frustration. Seb's snores drift into my ears, only making me feel even more pathetic.
I can't believe he fell asleep on me again.
My frustration bubbling to the surface, I wipe away the tears gathering in the corners of my eyes before climbing out of bed.
Fine. If he doesn't want to help me out, I might as well help myself. It's the reason I bought several vibrators after all, although Seb has no knowledge of them. If he did, he'd probably get really upset that I'm relying on artificial tools for sexual satisfaction.
I bet he'd even call me a slut again.
He's not a fan of sexual fantasies. Yet somehow, I'm engaged to him when I know deep down that I love sex. I love being fucked and experimenting with new things with my partner.
Picking up my phone from the nightstand, I quietly make my way to my closet and grab one of my vibrators.
Seb is still sleeping soundly and completely oblivious when I tiptoe past him toward the bathroom.
Now, please don't get this wrong—sex isn't my problem, nor am I an addict. I simply crave satisfaction. Too bad my partner is too selfish to let me experience that with him.
I couldn't possibly cheat on Sebastian even if I wanted to. It'd break him. I know how much he loves me, and I love him just as much. It's the reason we've been engaged for nearly six months, after all. Seb has sacrificed a lot for me, and I'm not an ungrateful bitch, so no, cheating is out of the question.
However, this unfinished sex issue is starting to become a real problem for me. I don't know how much longer I can cope, and I promise, I've been enduring this torment for the entire three and a half years Seb and I have been together.
My therapist is the only person who knows how badly this issue has affected me. She's advised me to talk to my partner about it, but that hasn't turned out so well the few times I've tried.
Closing the bathroom door behind me, I walk over to the counter and lean against it before bringing up my phone.
I open the porn website and click on a video titled, 'Fucked by My Boyfriend's Brother.'
Nice.
But I quickly shake off the possibility of it ever becoming my reality. I mean, having to get fucked by Sebastian's billionaire brother, Zane Thorne, a.k.a. the arrogant prick of the Thorne family? That would be wild.
I don't even like the guy enough to even entertain thoughts like that, so I shake my head, refocusing on the man and woman fucking on my screen.
Parting my legs, I settle my vibrator against my clit, letting it do its thing.
My back arches off the counter as I roll my hips, my eyes clouding with lust while waves of pleasure start to ripple through me.
A minute later, I'm this close to climaxing when an image suddenly pops onto my screen, replacing the porn video I was watching.
It's a picture of a shirtless man in grey sweatpants hanging low on his waist — would easily pass as a thirst trap. Tattoos spread across his broad, sculpted chest and trail down his big, muscular arms. The sight of his athletic physique nearly has me drooling.
Without bothering to look at his face, I quickly imagine those muscular hands holding my thighs apart while he eats me out. I picture those long tattooed fingers scissoring me from the inside out. My eyes drift lower across his body, catching the obvious outline of his monstrous cock through the grey pants.
I quickly reimagine it—him pinning me against the wall, my legs hooked up in those same hands, while he drives his massive cock into me… over and over again until I—
"Fuck, fuck, argh..." I whimper out loud, throwing my head back as my orgasm crashes down on me in a tidal wave.
My legs quiver, pleasure spilling through me as soft moans fall from my lips while I come undone.
I feel deeply satisfied by the time I come back from cloud nine. My chest rises and falls on a heavy exhale.
Fuck. That was intense.
What the hell.
Did I just come to a picture of an unknown man?
Does this count as cheating? I hope not.
I set my vibrator aside and reach for my phone again, wanting to see the stranger’s face.
I’m about to view the thirst trap—strangely sent by my boss, Will Owen—when I notice it has just been deleted.
Will’s apologetic message comes through immediately.
Will: Wrong picture, sorry. But it’s still the same man anyway. Below is the picture I intended to send you, Dahlia. And don’t ask why I had the first one on my phone. You know the dude is so hot, both genders want him in their beds… Anyway, he is your next interviewee. I believe you’re already familiar with him. Time for the interview is tomorrow, 7 PM sharp. At the Casa Bar he owns. Good night.
I immediately download the image he sends, and shock slams into my chest the moment I recognize him.
He’s no longer in grey sweatpants but now in a black tailored business suit, looking sharp, his presence effortlessly commanding as always.
His dark hair is slicked back from his forehead, revealing those intense blue eyes that feel like they’re piercing straight through me—like he somehow knows exactly what I just did with his picture.
My heart thunders with bewilderment as I stare at the unmistakable face of Zane Thorne—my fiancé’s fucking older brother. The same man I’d just said it would be disgusting to fantasize about, purely because I can’t stand him. And that's because he and my fiancé are not exactly on good terms.
But that’s beside the point…
What the hell just happened?
What the hell have I done?
Did I just… come… to the thirst trap of this asshole?
What the fuck, Dahlia?!

The CEO Above My Desk
“I know she does.”
“And what if she doesn’t want this kind of protection?”
“She will,” I say, my voice lowering slightly. “Because she needs a man who can give her the world.”
“And if the world burns?”
My hand tightens subtly at Violet’s waist.
“Then I’ll build her a new one,” I reply. “Even if I have to burn the old one down myself.”
I don’t work for Rowan Ashcroft.
I work beneath him.
From my desk, I decide who gets access to the most ruthless CEO in the city, and who never makes it past the lobby. I manage his time, his silence, his enemies. I keep his world running while my own quietly collapses under unpaid bills, a mother locked in rehab, and a brother who vanished without a goodbye.
Rowan Ashcroft is power wrapped in a tailored suit.
Cold. Untouchable. Merciless.
He doesn’t flirt. He doesn’t smile. He doesn’t see people, only usefulness.
And for a long time, I was just useful.
Until he started watching.
A shift in his attention is subtle at first. A pause too long. A look that lingers. Orders that pull me closer instead of pushing me away. The man who stands above my desk begins to control more than my schedule, and I realize too late that being noticed by Rowan Ashcroft is far more dangerous than being ignored.
Because men like him don’t crave affection.
They crave possession.
This was supposed to be a job.
Not a test of my limits.
Not a slow, deliberate descent into his authority.
But if Rowan Ashcroft decides I belong under his desk, then so be it.
Survival has a price, and the bills don’t care how I pay them.

My Billionaire Husband's Secret
He was the CEO of the Blackwood Group — a man whose wealth and power eclipsed ninety-nine percent of the world.
He was gentle. Romantic. Attentive. I fell for him fast.
But a year into our marriage, I began to notice something — a pattern.
Lucas's sexual appetite was intense — he wanted me almost every night. Yet every single month, he arranged a solo trip to send me away. I told myself it was his way of spoiling me.
Then a message arrived from someone called Sweet An.
Do you really know your husband?
From that day on, my life filled with shadows.
I suspected my husband of having an affair.
When Lucas and I made love, something felt wrong — his body too large, too much, like something I couldn't explain.
I heard sounds during sex — animal sounds, like something feral had crawled into bed with us.
My best friend Mia said: "There are men sick enough to let dogs fuck their wives."
The family doctor, Daisy, told me: "You could never stay by Lucas's side forever. Your background doesn't make you worthy of being his wife. Do you understand?"
I went looking for whoever had been tearing my marriage apart. I fought to win my husband back.
But the deeper I searched, the larger the secret grew — something far darker hiding beneath this supposed betrayal.
Does Lucas truly love me?
And why, out of everyone in the world, did he choose to marry me?
Letters to a Dark Prince
Thrown into Isteros Academy—a world of old money, blood money, and cruel social games—she's an outsider by birth and an afterthought by design. Her sister Solyn is the school's untouchable queen and Mara is her favorite target.
Everyone expects Atreus to treat his fiancée’s scholarship sister like everyone else does—as if she doesn’t matter.
Instead, his dorm room sits directly across from hers, close enough that she can see his light go out at night. Some nights, he climbs the old maintenance trellis just to check on her. He teaches her chess. He shows up exactly when something's gone wrong—and never once asks to be thanked for it.
"Don't fall in love with one piece," he warns her, over a board neither of them treats like a game anymore. "It punishes the person who only sees half of it."
Mara doesn't understand why the boy who's supposed to make her life harder keeps quietly making it easier—not until she realizes the anonymous stranger she's been writing to every week already has a name.
His.
He doesn't know he's writing to her, either.
By the time they find out, it's too late to stop what's already happening. Far too dangerous for anyone to find out.
In an empty studio, in the middle of a rainstorm, she asks him: 'Am I the kind of girl who kisses a boy engaged to my sister?'
He doesn't answer.
So she asks: 'What are we?’
He told her not to fall in love with one piece.
She fell anyway.
And he was never far behind.

Taste of Fate: The Vampire King's Human Mate
He reached for the back of my head and pulled me up just enough to reach my neck. When his fangs slid into me, the pain was instant, electric. I couldn’t breathe. I couldn’t think. My hands found his shoulders, clawing for something to hold. My legs kicked. Tears streamed down my cheeks.
He moaned against my throat as he drank, and the sound was devastating.
Tango 2 the Alpha's Heart
My gaze snapped to his. He was smiling, causing my heart to skip a painful beat. Before I could respond, the music began, and my body instinctively reacted to the sweet melody.
I found myself molded to Lex's will, my feet irresistibly following the dance steps.
The crowd gasped as Lex pulled me into a more intimate position, his hands roaming over my body in a seductive manner.
The experience was both terrifying and magical, allowing me to feel every longing emotion through the dance.
I soon found myself lost in his arms.
When the music finally stopped, my arms were wrapped around his neck, his hands resting on my back, our noses almost touching. He gazed deeply into my eyes.
The ballroom fell silent.
Was he about to kiss me?
