Page 18 of Only in the Dark (Bound By Darkness Duet #1)

“Don’t forget who is in control here,” I bit out, leaning down and licking some of the blood from his neck.

He groaned. “Fuck. You were carved from sin just for me, my little devil. I’ll bleed for you willingly whenever your darkness thirsts.”

His words caused the pace of my hips to increase, and I sloppily leaned over and jabbed my knife into Matthew’s thigh.

The sharp blade pierced his flesh, and his agonized screams echoed in my ears, igniting a twisted thrill inside me.

I left the knife embedded in his leg, and leaned forward, pressing my body against Kieran’s.

I switched to grinding my hips against his, seeking friction on my clit while he was buried inside me.

He didn’t complain as I circulated my hips.

I could tell he enjoyed it when his moans began to mix with mine, both of ours increasing in volume and filling the room.

No one would listen to Matthew’s screams because we were louder.

I loved the slow, sensual feeling, but I knew we both wanted things to be more rough, so I leaned up, bracing my palms on his chest. I kept myself at an angle where friction remained on my clit, but I bounced myself up and down harder and faster than before, ready to reward him for his effort, and ready to kill his brother.

I studied Kieran’s face—his almost black eyes, flushed cheeks, parted lips, and the new bite mark on his lip leaking a tiny amount of blood from where he had bitten it.

He looked devilishly handsome when he wore his long-sleeved shirts and remained quiet around me, but seeing him lose himself like this, hearing him moaning louder than me, drove me feral with need.

The blood falling from my ex’s body had an effect, too.

“I want you to fill me with your cum, Kieran. So deep inside me. I want to be reminded of you for days. I want to feel you drip from me while we leave this club together,” I told him between harsh breaths.

His grasp on my hips tightened, holding me in place while he pushed his hips up, burying himself inside me.

His hand slipped between us, fingers finding my throbbing clit and working it with rough, urgent strokes.

A ragged moan tore from my throat as my teeth sank into my lip, the sharp edge of pain only heightening the pleasure flooding through me.

My orgasm hit me fast, my walls clenching around him while I remained impaled on his cock.

I pressed my forehead to his chest, moaning against his sweaty skin as I felt every pulse of his dick as he unloaded inside of me, filling me completely in a way that made me crave more.

I had never let anyone finish inside me before Kieran. He would be my undoing.

The clank of metal became louder than our moans, interrupting my perfect orgasm, but I didn’t let it stop me as I bit his nipple, loving the sound of his grunt and the way his hips stuttered as the last of his orgasm ripped through him.

I collapsed against his chest, my breathing hot and heavy, my eyes on Matthew.

His brows drew together in a slow, deliberate pinch.

The corner of his mouth twitched, but no words came—only the quiet burn of a gaze that lingered too long to be anything but anger.

I could sense the shift in Matthew’s emotion from trying to preserve what he thought of me, to hating me.

He wouldn’t beg for me back anymore. He finally saw me for what I was inside—depraved. Dark. Deadly.

“I could lay like this forever if we didn’t have to take care of this fucking menace,” Kieran groaned, looking toward his brother with a scowl.

“I’m glad the last thing you saw before we ended you was me buried in your girlfriend.

When you’re rotting six feet under, she’ll be on top of me—finally learning what pleasure feels like. ”

Matthew hung his head low, an evil laugh taking over that had his body shaking before he made eye contact with Kieran. “You can’t kill me. You’re my brother and a detective. You’d get caught, and Mom and Dad would hate you. And Olivia, you wouldn’t hurt someone. You couldn’t. I know you.”

Now he was pissing me off. I didn’t want to remove myself from Kieran, but I carefully lifted my hips and hissed at the burn of his cock leaving me.

I felt myself dripping a mix of Kieran and I’s cum when an idea struck.

I reached between us and inserted two fingers into myself, scooping up some of the remnants left behind.

I smirked down at Kieran as his eyes widened.

Matthew’s jaw slackened, and his brows knotted in a grimace of disbelief while he began shaking his head, his lips now sealed tight.

I would’ve paid to see the look on my face from Matthew’s point of view as I forced my fingers through his lips, shoving them to the back of his throat so he couldn’t miss the taste.

“You never knew me at all, Matthew. You saw the girl I pretended to be. Kieran lets me be free.”

I grabbed the knife and jabbed it into his other thigh, his agonizing screams music to my ears.

“That is for telling me I wanted you to keep your small, unsatisfying dick inside of me when I told you to stop. You covered my mouth and grunted for all of two minutes before it was over, but it didn’t make it any better.

I was never just a sex toy for you to use. ”

“Fuck, Olivia! That fucking hurts, you bitch. I can’t wait until you and Kieran are in jail for the rest of—”

I removed the knife from his thigh and thrust it into his neck, enjoying the sound of his gasping breaths and how his eyes widened when I pulled the knife from his neck.

The blood poured from the wound, falling onto the pillows, comforter, and headboard.

It only took a minute for his body to go slack in the handcuffs.

I remained frozen, a devilish grin planted on my face while I looked down at his dead body.

Killing someone with violence and blood was better and more freeing than I expected.

Mother lied. I loved it.

“Olivia,” Kieran whispered, his hand landing on my shoulder. I turned to face him. I thought he’d be mad at me, but he didn’t look worried or upset in the slightest.

“Shit. This wasn’t the best place. Th—that was—oh, fuck. I wasn’t thinking. I’m so sorry. This is a whole mess to clean up, and the owner of the club is going to turn us into the cops. I’ve just ruined our lives.” My breath quickened, my heartbeat frantically rising.

“Hey, hey. Breathe. Calm down. Everything is fine. The owner is going to have this room professionally cleaned. He’s a cool guy—smart, handsome, a bit of an obsessive stalker,” he explained, chuckling before winking.

“You’re the owner?” I questioned, tilting my head. My first thought was to be jealous that Kieran owned a sex club. Did he…bring girls here? Did he come here often? I couldn’t stop the jealous thoughts that angered me. My grip on the knife tightened.

“I’m the owner, but I don’t come meet people here.

At least not in years. I’ll bring you here and show everyone you belong to me if you want.

Detectives don’t make much, and I didn’t want my father’s money, so I started a business of my own.

Put the knife down, and let’s get out of here for the night and talk. ”

“Before we walk out of here and talk about a future relationship…there’s something you should know.

There was a reason I chose Matthew and stayed with him despite what he became.

And now, I’ll need to use you to finish what I started.

But if you hurt me, or double-cross me, I will kill you, Kieran,” I explained. It would be the last test for us.

“Fuck. I love it when you threaten me. Let’s go home and talk about it before I take you right here, again, next to my brother’s dead body,” he said.

He stood up from the bed and outstretched his arm toward me, and I took it. I couldn’t stop my lips from parting and a small groan of desire from escaping. “Christ, Little Serpent. You’re going to keep my hands full and my dick hard for the rest of our lives.”

I looked toward the bed. “And what exactly are we doing with your brother’s dead body?” I asked, a brow raised when my eyes locked on Kieran again as he put on his clothes.

“Easy. I’ve brought his disturbing proclivities to light, and now he’s going to disappear and leave behind a note on his computer. I have someone coming to take care of the body. I’m a serial killer, after all. I have plenty of hidden bodies.”
