Chapter 1: The Steep Trail
The air smelled of damp earth and pine resin. Sunlight filtered through the canopy of towering trees, painting the trail in shifting patches of gold and deep, cool shadow. Alex’s breathing was already a little ragged, but it had nothing to do with the incline.
It was all Natalie.
She was just a few steps ahead on the narrow path, her form a study in motion. The tight black spandex of her leggings seemed to drink in the scattered light, stretching and releasing over the curves of her backside with every step she took. It was a perky, impossible shape, a perfect bubble that swayed like a hypnotic pendulum just inches from his face. He could see the fine seams, the way the fabric clung to the dimple of each hamstring as she pushed off the ground.
“This is a good pace, right?” she called over her shoulder, her voice bright and effortless. She didn’t even sound winded.
“Yeah,” Alex managed, the word coming out strangled. He forced his eyes to the trail, to the gnarled roots snaking across the dirt. He counted to three. Looked back up. Mistake. The incline steepened right there, and she leaned forward slightly for balance, the position amplifying everything, throwing the architecture of her body into devastating relief. His mouth went dry.
He’d been here a thousand times in his head. Daydreams in his quiet bedroom, fleeting glances at family barbecues where she’d hug him hello, her body soft and pressing against his for a torturous second. She was his cousin, older by three years, and she treated him with a kind of breezy, affectionate neglect—pulling him into selfies, ruffling his hair, completely unaware that he’d memorized the cadence of her laugh, the scent of her coconut shampoo.
Out here, it was a whole new kind of agony. An intimate, shared solitude where his secret felt like a physical weight in his chest.
“You’re quiet today,” Natalie said. She paused on a flatter section, turning to take a swig from her water bottle. Her neck arched, a tendril of dark hair sticking to her damp temple. Her sports bra was a vivid blue against her skin. She smiled at him, a genuine, crinkled-eyed smile that was somehow worse than any sexy pose. It was friendly. Sisterly.
“Just… taking in the scenery,” he said, immediately cringing inwardly. Idiot.
“It’s beautiful, isn’t it?” She capped her bottle and hooked it back on her pack, her gaze sweeping the forest. She missed the way his eyes dropped again, helpless, tracing the line where her leggings met the waistband of her shorts. “Way better than being stuck inside. I needed this.”
“Me too.”
They started moving again. The trail narrowed further, forcing him to fall directly behind her. The space between them crackled with a tension only he felt. The rhythm was torture: the firm planting of her foot, the roll of her hip, the gentle, mesmerizing jiggle. His own heartbeat was a frantic drum in his ears, drowning out the distant birdsong. He felt lightheaded, a weird mix of oxygen debt and pure, undilwant.
His thoughts were a sticky, messy loop. Don’t stare. You’re staring. She’ll feel it. Look away. Look at that tree. That’s a cool rock. Oh god, look at it. Just look. No one will know.
But he was burning up with it. The secret was going to spill out, he was sure. It was a pressure valve turning, screaming to be released.
She stopped short to avoid a low branch, and he almost walked into her. He caught himself, his hands flying up, stopping just short of planting on her hips. He could feel the heat coming off her.
“You okay there, klutz?” she laughed, glancing back.
The words were out before he could catch them. They just fell from his lips, cracked and too loud in the quiet woods.
“It’s just… your ass. It looks incredible in those.”
Silence.
The moment hung in the air, thick and hot. The chirping birds might as well have vanished. Natalie went very still. She didn’t turn around.
Alex felt the bottom drop out of his world. His face flamed, a wave of nausea rolling through him. He hadn’t meant to say it. Not like that. Not so bluntly. A rush of panic flooded his veins, icy and sharp.
Natalie slowly turned her head, just enough for him to see her profile. Her bubbly expression was gone, replaced by something unreadable. Confusion? Disbelief? There was a slight frown between her eyebrows.
“What did you say?”
He couldn’t backtrack. He couldn’t pretend she misheard. The truth was a pile of grenades at his feet, and he’d just pulled the pin. His voice was a hoarse whisper, all pretense stripped away.
“I said… your butt. It’s amazing. I’m sorry. I just… I couldn’t not say it.”
She finally turned fully to face him. Her cheeks were flushed, but not from the hike. Her dark eyes searched his face, not with anger yet, but with a dawning, horrified comprehension. She was seeing him—really seeing him—for the first time. The easygoing little cousin was gone, and in his place was this guy, this stranger panting on the trail, his desire laid bare and ugly between them.
She didn’t speak. She took a small step back, up the trail, putting distance between them. The friendly energy that had surrounded her was gone, replaced by a cautious, charged stillness. The air hummed with what he’d done.
Alex stood there, ruined, waiting for the world to end. For her to scream, to call him a creep, to turn and run back down the mountain.
Natalie just swallowed, her gaze dipping to the forest floor for a second before snapping back to his. Her voice, when it came, was quiet. Flat. Totally unlike her.
“We should keep moving,” she said. “The viewpoint’s not much further.”
Then she turned and started walking again, her posture stiff, her pace quicker. The sway was still there, but it wasn’t a tease anymore. It was a weapon. And he was destroyed by it.
And he was destroyed by it.
The rest of the climb passed in a blur of crushing silence. The only sounds were their footfalls on the packed dirt, the rustle of their gear, and the deafening rush of blood in Alex’s ears. He kept his eyes fixed on the trail, on her heels, anywhere but on her. His face burned with a shame so profound it felt like a physical sunburn.
When they finally broke through the tree line onto the rocky viewpoint, the vista of endless rolling green mountains was wasted on him. Natalie walked to the edge, her back to him, and dropped her pack. She stood there, arms crossed, staring out.
Alex hung back, paralyzed. He fumbled with his own water bottle, the plastic crinkling loudly in the quiet.
“So,” she said. She didn’t turn around.
“Natalie, I’m—“
“Just stop.” Her voice cut through the mountain air, sharp and final. She took a deep breath, her shoulders rising and falling. “What the hell was that, Alex?”
“I don’t know.” It was the truest thing he’d ever said.
“You don’t know?” Now she turned. Her expression was fractured—confusion, embarrassment, a flicker of something else he couldn’t name. “You’re my cousin. You’re my little cousin. I buy you birthday presents. I helped you with your calculus homework.”
“I know.” He felt small, shriveled. “I know what I am. I know what you are. It doesn’t… it doesn’t change what I see.”
She blinked, her gaze dropping to his hands, to his mouth, then back to his eyes. She was assessing him, not as family, but as something else. The calculation in her look was new. Dangerous. “How long?” she asked, her voice lower.
“A while.”
“How long is a while?”
“Years.” The admission was a gut-punch, to both of them. He saw her flinch.
“Jesus Christ, Alex.” She ran a hand through her hair, looking away again, out at the vast emptiness. “Years? And you just… what? Stare at me? At my…?” She trailed off, unable to say it.
“It’s not like I plan it.” His own voice gained a desperate edge. “You walk into a room. It’s there. You bend over to get something from the fridge. It’s there. You wear fucking leggings on a hike and walk in front of me for an hour. What the fuck am I supposed to do? Ignore it? I’ve been trying to ignore it for years!”
His outburst hung between them. A jay screamed somewhere in the pines below.
Natalie was silent for a long time. When she spoke again, her voice was oddly calm, detached. “So, out here, with no one else around… you just decided to tell me. To put that on me.”
“I didn’t decide anything. It fell out of my mouth. It’s all I’ve been thinking about the whole damn hike. You have no idea… no idea what it does to me.” He took a step toward her, then stopped, fists clenched. “You’re all I think about. In that way. The worst, most fucking wrong way possible. I know it’s wrong. I don’t care anymore.”
She finally looked at him, really looked, and her detached calm cracked. Her eyes were wide, dark pools of shock, but beneath it, a spark of something warm and curious. Her gaze traveled over his lean frame, seeing the tension in his shoulders, the tight line of his jaw. A slow, deep blush spread from her neck up to her cheeks.
She laughs nervously.
The sound was brittle, out of place in the vastness. It was a shaky exhale of disbelief. “This is insane,” she murmured, more to herself than to him. She uncrossed her arms, letting them hang at her sides. Her fingers twitched.
“Yeah,” he agreed, breathless. He saw the conflict in her—the lifetime of family boundaries warring with the raw, illicit thrill of being wanted so viscerally. He saw her eyes dip, for a fraction of a second, to the front of his hiking pants. He knew she saw the evidence of his obsession, straining against the fabric.
That one glance broke the last barrier.
It was an invitation. A collapse.
He closed the distance between them in two strides. He didn’t grab her, didn’t kiss her. He just stood, inches away, his body screaming at hers. The clean scent of her sweat and coconut shampoo filled his head. “Tell me to stop,” he whispered, his voice ragged. “Tell me to go to hell, Nat. Right now.”
She didn’t tell him to stop. She didn’t speak. She just looked up at him, her lips slightly parted, breathing fast. Then, with a slow, deliberate motion, she turned around and placed her hands on the sun-warmed rock ledge, presenting herself to the view, and to him. A silent, devastating consent.
It was the most obscene, beautiful thing he’d ever seen.
A groan ripped from his throat. His hands, clumsy with tremors, found her hips. The spandex was slick under his palms. He pressed himself against the perfect, round curve of her ass, grinding into her, letting her feel every hard, aching inch of him. She gasped, pushing back against the friction.
“You have no idea,” he snarled into her ear, his voice thick with want. “No fucking idea how many times I’ve dreamed of this.” He slid one hand around her front, fumbling with the button of her hiking shorts. It gave way. The zipper hissed down. He shoved his hand inside, beneath the waistband of her leggings, beneath her underwear. His fingers found her hot and already slick.
“Oh, God,” she choked out, her head dropping forward.
“Yeah,” he said, working his fingers into her. She was tight, wet, fucking perfect. He curled them, feeling her clench around him. “You like that? You like your little cousin wanting you this bad? Wanting to ruin you?”
She answered with a low, broken moan, rocking her hips against his hand. He added another finger, stretching her, his other arm locking around her waist to hold her still. He could feel her heart hammering against his forearm. He watched his own tanned fingers disappear into her, into the darkness of her clothes, and the sight nearly made him come right there.
He pulled his hand free, ignoring her soft cry of protest. He yanked her shorts and leggings down over the swell of her ass in one rough motion, down to her thighs. The cool mountain air hit her skin, and she shuddered. He unfastened his own pants, freeing his cock, which was painfully hard, the tip flushed and wet. He didn’t wait. He didn’t ask.
He positioned himself at her entrance and drove into her in one deep, brutal thrust.
She cried out, a sharp sound swallowed by the valley. He was not gentle. He couldn’t be. This was a fantasy breaking into reality, messy and raw and wrong. He filled her completely, a tight, hot fist around him. He froze for a second, buried to the hilt, forehead pressed against her shoulder, overwhelmed by the sensation of finally being inside her.
“Fuck,” he breathed, the word a prayer and a curse.
Then he began to move.
He fucked her with a relentless, punishing rhythm, his hips slapping against the exposed flesh of her ass. Each thrust drove her forward against the rough rock. The sounds were filthy—the wet slap of skin, their ragged breathing, her sharp little gasps. He gripped her hip so hard he’d leave bruises, his other hand tangling in her hair, pulling her head back to expose her throat.
“This what you wanted?” he grunted, pistoning into her. “Walking up here, swinging that perfect ass in my face? You knew. You had to know.”
“I didn’t,” she panted, but the denial was weak, broken by a gasp as he hit a deep spot. “Alex… oh, fuck…”
“You knew.” He slammed into her, again and again, the pleasure coiling tight and vicious in his gut. The world narrowed to the feeling of her cunt gripping him, to the sight of her taking him, to the sheer, devastating wrongness of it. “This is mine now. You understand? This,” he thrust hard, “is mine.”
Her answering cry was muffled as she bit her own arm. He felt her inner muscles begin to flutter, a frantic, rhythmic pulse. She was close. The knowledge pushed him toward the edge. His rhythm faltered, going fast and erratic.
“Come for me,” he demanded, his voice guttural. “Come on your cousin’s dick, Natalie. Do it.”
The command, the crude permission, tipped her over. She shattered with a choked scream, her body clamping down on him like a vice, waves of pleasure milking his cock. It was too much. With a final, deep plunge, he spilled into her, a hot, flooding release that seemed to tear something loose from his soul. He held himself there, pulsing, emptying, his vision going white at the edges.
Silence descended, broken only by their heaving breaths. The vast mountains sprawled before them, indifferent.
Slowly, reality seeped back in. The chill of the air on his sweat-dampened skin. The rough grit of the rock under his hands. The feel of her, still connected to him, soft and used.
He softened and slipped out of her. A slick, shameful warmth trailed down her inner thigh. He stared at it, the physical proof of what they’d done.
Natalie didn’t move. Her shoulders were tense, her head still bowed. He gently pulled her leggings and shorts back up over her hips, his fingers clumsy. The intimate act felt more violating than the sex had.
She straightened up slowly, wincing, and turned to face him. Her expression was utterly blank, wiped clean of any emotion. She looked at him, through him, at the man who was both her cousin and her lover. Her voice, when it came, was flat and hollow.
“We should go back.”
