THE LETHAL CURVE

CHAPTER SIX: ENTHALPY OF REACTION

By 8:30 PM, the heavy rain had turned into a full-blown autumn torrential downpour. Thunder rumbled low and deep across the night sky, rattling the old glass panes of the craftsman house.

In the living room, Leo was zipping up his rain jacket, slinging a gym bag over his shoulder.

"You guys sure you don't want to come to the team dinner at the grill?" Leo asked, grabbing his truck keys from the entry table. "It's all-you-can-eat wings night, and half the athletic squad is going to be there."

"I have three synthetic pathway databases to cross-reference before morning, Leo," I said, without looking up from where I sat at the head of the oak dining table.

My laptop was open, surrounded by three highlighters, two textbooks, and a stack of color-coded index cards. My dark hair was clipped up loosely, a few soft strands falling against my neck, and I had traded my blazer for a soft, oversized dark slate sweater.

"And I'm not letting her write the outline alone because she'll leave out my electro-permeabilization model," Damon said smoothly.

He was sitting at the side of the table—directly to my right—wearing a dark black t-shirt that fit snugly over his chest and shoulders. He was relaxed, leaning back in his chair with a pen spinning effortlessly between his long fingers.

Leo laughed, shaking his head as he pulled open the front door. "Suit yourselves, nerds. I'll probably be back around midnight. Try not to burn the house down arguing over cell membranes."

The heavy oak front door clicked shut, followed by the sound of Leo's truck engine turning over in the driveway before pulling away into the storm.

The silence that settled over the house was immediate, thick, and suffocating.

The rhythmic pounding of rain against the dining room windows seemed to amplify every small sound inside: the hum of my laptop fan, the quiet click of Damon's pen, and the heavy, electric static hanging between us in the isolated house.

"Now that your brother is gone," Damon growled out softly, his voice dropping an octave into that rough, smoky register, "we can stop pretending this outline is going to take four days."

I kept my eyes glued to my screen, typing out a heading in our shared document. "It will take as long as it needs to take to ensure total academic superiority."

"Elena," Damon said.

Just my name. Low, deep, and carrying enough smooth command to make my fingers stall over the keyboard.

I turned my head to glare at him.

Damon had stopped spinning his pen. He was leaning his forearms against the dark oak table, shifting closer to me. The yellow light from the chandelier above caught the sharp contour of his jawline and the intense, dark amber depth of his eyes.

"You've typed the same sentence three times," Damon purred, his dark eyes locking onto mine with an unhurried, predatory patience. "You're distracted."

"I am not distracted," I stated coldly, though my pulse twitched visibly against my neck. "I am organizing Section Two."

"Section Two is enzyme kinetics," Damon rasped, reaching out with one broad hand.

His long fingers slid across the polished wood of the table, lightly touching the edge of my laptop screen and pulling the display down by forty-five degrees, closing the barrier between our faces.

"What are you doing?" I demanded, my voice tightening.

"Removing the distraction," Damon said smoothly.

He didn't pull his hand back. Instead, he reached out further, his fingers resting over mine where they clutched my pen. His palm was broad, burning warm, and calloused against the back of my hand.

A sharp, violent jolt of heat shot straight down my spine, settling in the pit of my stomach.

I didn't pull away immediately. I couldn't. My body seemed to betray my logical mind every single time he breached the boundary.

"We have four days to submit this to Dr. Hayes," I breathed, trying to anchor myself to the cold, analytical reality of our work. "If we fail to integrate both methodologies, he will dock five percent from our total standing."

"Do you really think I care about five percent right now?" Damon growled softly.

He stood up from his chair.

Towering over me, his broad frame blocked out the light from the hallway. He stepped around the corner of the table, closing the distance between us until his knees were resting against the side of my chair.

I sat frozen, my chin tilting up as he leaned down, resting both of his palms on the wooden armrests of my chair, effectively trapping me beneath him. The heat radiating off his body was like an open flame, carrying that dark, intoxicating scent of cedarwood, rainfall, and clean skin.

"Damon..." I whispered, my voice coming out thin, stripped of every piece of authority I possessed.

"Three years, Elena," Damon rasped, his eyes burning into mine with a fierce, possessive hunger that made my lungs seize. "Three years of watching you walk into that lecture hall. Three years of listening to you talk about grading curves while you looked at me like you wanted to rip my head off."

His right hand left the armrest, his warm, rough fingers cupping the side of my jaw. His thumb brushed lightly across my bottom lip, sending a wave of electric shivers crashing over my skin.

"You think this tie on the board is an accident?" Damon purred, his voice dropping into a dangerous, dark whisper against my cheek. "You think I stayed up until four in the morning every exam week just for a grade?"

My heart slammed against my ribs so hard it felt painful. My eyes widened slightly as the realization hit me through the haze of heat.

"You... you stayed tied with me on purpose?" I breathed.

A slow, lethal smirk touched Damon’s lips, but his dark eyes remained intensely serious.

"I stayed on your level because it was the only way to keep your eyes on me," Damon admitted growlingly, his thumb pressing a fraction firmer against my lip, parting them slightly. "Because if I fell behind, you'd ignore me. And if I passed you, you'd hate me."

"I do hate you," I whispered, my chest heaving as my pulse hammered against his palm resting on my jaw.

"Lie to me again," Damon purred, leaning down until his lips were bare millimeters from mine. "Tell me you want me to move out of this house. Tell me you want me to walk out that door right now."

My breath hitched. The thunder roared outside, shaking the glass, but inside the room, everything had shrunk down to the space between his mouth and mine. The line between rivalry, academic pride, and absolute, forbidden desire disintegrated into dust.

"I..." The word died in my throat.

Damon didn't wait.

He closed the final distance, his lips meeting mine in a deep, heavy, possessive kiss that instantly swept away every logical thought in my head.

A soft gasp escaped my lips, and Damon took total advantage, his hand sliding down from my jaw to grip the back of my neck, his long fingers tangling into my hair, pulling me tighter against him. The kiss wasn't gentle—it was demanding, intense, and filled with three years of built-up, explosive tension that had finally snapped.

My hands, which had been pressed flat against the wooden armrests, instinctively flew up. My fingers gripped the dark fabric of his t-shirt, pulling his broad chest flush against mine. The heat of his body was overwhelming, his taste dark and rich like black coffee and rain.

Damon growled low in his chest at my response, his other arm wrapping around my waist, lifting me effortlessly out of the chair until I was standing, my front pressed completely against his long, muscular frame.

He backed me up two steps until my hips hit the edge of the oak dining table.

Paper notes scattered across the floor, pens rolled off the wood, but neither of us cared. Damon parted my knees with his thigh, stepping between them, his hands sliding up under the hem of my slate sweater to rest on the warm, bare skin of my waist. His touch was burning, rough, and completely authoritative.

I tilted my head back, letting out a breathy sigh against his mouth as his lips trailed down from my lips to the sensitive curve of my jaw, then down to the exposed skin of my neck.

"Tell me this is a distraction, Vance," Damon rasped against my skin, his teeth lightly grazing my collarbone, making a shockwave of heat ripple down to my toes.

"You're... infuriating," I managed to choke out, my hands tangling into his thick, dark hair, pulling him closer as my head spun out of control.

"And you're mine," Damon growled out, his dark eyes snapping back to mine as he pulled back just an inch, his breathing as heavy and ragged as my own. His hands remained firmly locked onto my waist, holding me pinned to the table. "Not Hayes's. Not the board's. Mine."

Before I could answer, the sharp, shrill ring of a cell phone echoed from the living room counter.

The sudden noise shattered the high-heat trance like a bucket of ice water.

We both froze, our chest heaving in unison, our breath fanning across each other's lips.

The phone rang a second time—it was Leo’s custom ringtone for my mobile.

Damon didn't let go of my waist immediately. His dark eyes burned into mine, filled with an unyielding, possessive fire as he slowly, reluctantly eased his grip, stepping back just enough for me to catch my footing against the table.

I smoothed down my slate sweater with trembling hands, my face burning with a fiery flush, my pulse still racing at a hundred miles an hour.

"Answer it," Damon growled softly, his voice thick and rough, his dark gaze tracking every movement of my chest as I breathed. "Before your brother thinks you've died over Section Two."

I took a deep, shaky breath, steadying my trembling hands as I stepped around him, picking up my phone from the counter.

"H-hello?" I said, forcing my voice into its usual calm, clinical tone.

"Hey El!" Leo's cheerful voice boomed through the speaker over the background noise of a loud restaurant. "Hey, the roads near the highway are totally flooded from the storm. The police closed the south bridge. Looks like I'm going to have to crash at Tyler's apartment in town tonight."

My heart did a violent flip in my chest.

I looked back toward the dining room. Damon was leaning against the table, his arms crossed over his chest, his dark eyes locked onto me with a slow, wicked, and completely dangerous realization as he heard Leo's voice over the speaker.

"You... you're staying in town?" I asked, my knuckles turning white around the phone.

"Yeah, won't be back until morning," Leo said easily. "Tell Damon he's in charge of making sure you actually go to bed and stop studying. See you guys tomorrow!"

The line went dead.

I slowly lowered the phone, the silence returning to the house with a crushing, suffocating weight.

Damon pushed off the table, taking one slow, deliberate step toward me through the dim light of the hallway.

"Looks like it's just you and me tonight, Elena," Damon purred softly, a dark, lethal smirk cutting across his sharp jawline. "Let's see how much of that outline we can get through."
