The sun had already slipped below the horizon, painting the cove in deep indigo and gold, when Rick's voice cracked across the dock like a snapped halyard.
"Goddammit, Kai—that's a granny knot *again*. How many times do I have to show you before it sticks in that thick skull of yours?"
Lila paused on the back porch, screen door half-open, and watched her husband tower over their son at the edge of the private dock. Rick was built like the boats he sailed—broad, weathered, unyielding—salt-and-pepper hair catching the last light. Kai stood a little shorter, leaner, shoulders tight beneath his faded navy T-shirt as he fumbled with the rope. The twenty-eight-foot sloop *Siren's Kiss* rocked gently against the pilings, hull still gleaming wet from the afternoon wash.
"I'm trying, Dad," Kai muttered, jaw locked.
"Trying ain't sailing," Rick growled. "This weekend we're taking the *Siren* out with the club. You're twenty-eight years old, for Christ's sake. Last time you embarrassed me in front of the guys with that sloppy bowline, I heard about it for weeks. Two days, Kai. Get your head out of the clouds and into the rigging, or stay home."
He clapped a heavy hand on his son's shoulder, then stalked up the dock, muttering under his breath.
Kai didn't move. He stared at the rope as if it had personally betrayed him, the humid breeze ruffling his dark hair. Lila's chest tightened. She knew that look. Rick's standards were sky-high—especially for the boat he'd poured his soul into. Kai had always been more bookish than nautical, happier with a sketchpad or laptop than a winch handle. But he tried. God, he tried.
She waited until the screen door slammed behind Rick before she stepped down the wooden stairs, her bare feet silent on the warm planks. The thin yellow sundress clung to her like a second skin, the humid air rendering the cotton nearly sheer. It molded to the full swell of her breasts, the damp curve of her waist, the generous flare of her hips. A light sheen of sweat glistened along her collarbone, and she knew her nipples were already visible, two dark points pressing against the fabric.
"Kai," she said softly. "Come here."
He looked up. Hazel eyes flecked with green flicked over her once—quick, guilty—before locking on her face. *Fuck. Not her. Not right now.* "Mom… it's fine. I'll practice more tomorrow."
"No." Lila crossed the dock until the rope lay between them like an unspoken invitation. "Not tomorrow. Tonight. After your father goes to bed. Meet me back here at ten. We're going to make sure you can surprise him this weekend."
Kai's throat worked. "You don't have to—"
"I *want* to." She reached out and brushed a stray lock of hair from his forehead. Her fingers lingered, skin warm against skin. "He's hard on you because he cares. But I know a better way to teach. Just you and me. No yelling. No pressure."
Something dark and hungry flickered in his gaze. He nodded once, sharp.
"Ten o'clock," she repeated. Then she turned and walked back toward the house, the hem of her dress brushing the backs of her thighs. She could feel his eyes on her the entire way up the porch steps.
By ten the house was dark and quiet. Rick's snores drifted from the master bedroom window. Lila slipped out barefoot again, the same sundress now slightly damp from a quick shower she'd taken on purpose. The night air wrapped around her, thick and warm, carrying the low hum of cicadas and the gentle lap of water against the hull. She carried a small coil of soft, well-used sailing rope.
Kai was already waiting by the *Siren's Kiss*, leaning against a piling in loose cargo shorts and a clean black tank that hugged the lean lines of his chest. His arms were crossed, shoulders rigid.
"Ready?" she asked, stepping onto the dock.
"Yeah." His voice came out rougher than usual. "What are we starting with?"
"Bowline first," Lila said, hopping lightly onto the boat's deck. The sloop rocked beneath her, making her breasts shift beneath the thin fabric. No bra tonight—just soft cotton and the cool kiss of night air on her nipples, turning them into tight, aching peaks. "Then a clove hitch. Simple, strong, perfect for tying off at anchor. Come on."
She knelt on the cockpit bench and demonstrated with slow, deliberate movements. The rope felt rough and alive against her palms. "Watch. Rabbit comes out of the hole, around the tree, back down the hole. Easy."
Kai climbed aboard. The boat dipped under his weight. He crouched close—too close—his knee brushing her bare thigh. She showed him again, then placed her hands over his. Her full breasts pressed softly against his upper arm as she leaned in, guiding his fingers. Heat flared between them. His skin was warm, damp with nervous sweat, muscles flexing under her touch. Jasmine and coconut from her lotion mingled with his clean soap and that raw, masculine scent that made her pulse throb low in her belly.
"Like this," she murmured, her voice softer than she intended. She moved his fingers. The rope slid between them. His breath hitched. The knot held—barely.
"See? You've got it." She pulled back just enough to meet his eyes, but her thigh stayed pressed to his. Moonlight caught the faint sheen of sweat tracing down between her breasts, visible where the neckline dipped low.
Kai tried again on his own. His eyes kept drifting—to the way the fabric clung to her full breasts, to her stiff nipples clearly outlined against the cotton, to the smooth stretch of thigh where her dress had ridden up. The rope slipped.
"Focus, baby," Lila teased gently, though her own pulse was racing. She reached over once more, deliberately letting her breast brush his bicep. The soft, warm weight lingered for a heartbeat. "Feel the rope. Trust the motion."
He swallowed hard. "It's… hard to focus." *She's my mom. This is so fucked up. Why the hell is my cock this hard?*
The words hung between them, heavy with everything he wasn't saying. Lila felt a slow, secret thrill race down her spine. She knew exactly why. She'd seen the way he looked at her lately—not like a son, but like a man who noticed every curve, every sway. Tonight, with the boat rocking gently and the world reduced to water and cicadas, that look burned hotter than the night air.
She didn't pull away. For the clove hitch she stood behind him, her front pressed lightly to his back as she reached around to demonstrate on the railing. Her hard nipples grazed his shoulder blade through the thin dress. Her breath brushed the shell of his ear.
"Twist it like this… cross it over… there. Good boy."
Kai's hands trembled. The knot held this time, but when he turned to face her, his cheeks were flushed dark. His cargo shorts did nothing to hide the thick, unmistakable bulge straining against the front. He shifted, trying to angle his body away, one hand dropping casually to cover himself.
Lila's gaze flicked down for the briefest second. Her lips parted. Heat flooded between her thighs, sudden and slick. She kept her voice light, full of promise.
"Looks like the lesson's getting to you," she said softly, eyes meeting his again. The air between them crackled. "We'll work on that concentration tomorrow night. Same time. Don't be late."
She stepped back onto the dock, wood creaking under her bare feet, and left him there—rope still in his hands, erection throbbing visibly, the taste of salt and jasmine lingering in the warm night air.
Kai watched her go, heart hammering against his ribs, already aching for whatever came next.
The midday sun hammered the cove like it had a personal grudge. Heat rippled off the water, thick and sticky, while the *Siren's Kiss* rocked lazily at the dock, its white hull throwing blinding shards of light. Rick had left for an emergency repair job at dawn, so the boat—and the whole afternoon—was theirs. Lila had made damn sure of it.
She stood on the foredeck in a cropped white tank top that stopped just below her ribs and faded denim shorts so short the pockets hung out beneath the frayed hems. The thin cotton clung to her sweat-damp skin, neckline scooped low to show the deep valley between her full breasts. A single bead of sweat slid down her cleavage and vanished into shadow. Her nipples—already tight from the occasional breeze—pressed hard against the fabric. No bra. On purpose. The shorts hugged her ass like they were painted on, riding up every time she moved and flashing the soft lower curve of her cheeks.
Kai climbed aboard with the coil of rope, his own tank already plastered to the lean muscle of his chest. His eyes locked on her immediately—dragging over her bare stomach, the way the shorts dug into her thighs, the faint tan lines peeking out.
"Same time as last night?" he asked, voice hoarse. "Or start fresh?"
Lila smiled, slow and knowing. "Fresh. Bowlines, clove hitches, then sheet bends. You need these in your sleep by the weekend." She turned and bent over the starboard rail to adjust a cleat, deliberate as hell. The shorts pulled tight across her ass, rounded cheeks spilling slightly over the edges, seam pressing between them. She felt his stare like a physical touch.
Kai swallowed hard enough for her to hear it.
"Watch closely," she said, straightening. She took the rope from him, fingers brushing his knuckles. The hemp was sun-warm and rough. "Rabbit out of the hole, around the tree, back down. Simple."
He tried. His fingers fumbled. His gaze kept slipping—to the shift of her breasts when she demonstrated, to the sweat making her skin glow, to the way her ass flexed every time she shifted her weight. The knot fell apart for the third time.
"Kai," she scolded playfully, stepping closer. The boat rocked, pressing her body into his space. "Eyes on the rope, not on my tits."
His face burned red. "I'm trying, Mom. It's just… hot as hell out here."
"Mmm. It is." She reached up to tuck a strand of hair behind her ear, the motion lifting her tank higher and exposing another inch of soft, sun-warmed skin. "Here. Let me show you again."
She moved behind him, pressing her front flush to his back exactly like last night. Her heavy breasts pillowed against his shoulder blades, hard nipples dragging through the thin tank. She reached around, covering his hands with hers, guiding the rope.
"Feel it," she murmured against his ear, breath warm and sweet from iced tea. "Slow. Deliberate. Don't rush the loop."
His body tensed hard. She felt the tremor in his arms, the heat pouring off him. The thick bulge in his shorts was already straining, pressing against the fabric right in front of her. Under her guidance the knot held—but only because she stayed glued to him, hips brushing the small of his back.
"Good boy," she whispered. "Now do it without me."
It fell apart instantly.
Lila circled to face him, leaning her hip against the rail. "You're distracted, baby. What's got you so worked up today?"
Kai's jaw clenched. His eyes dropped again—to the sweat tracing down her throat and disappearing between her breasts, to the way the shorts cupped her mound, to the perfect heart-shaped ass that filled his vision every time she turned. *Fuck. She's my mom. I shouldn't be this hard. I shouldn't want to bend her over the rail and—*
"Nothing," he lied.
She didn't believe him for a second. Instead she took the rope, looped it around her own wrist in a quick bowline, and pulled it snug. The rough fibers bit gently into her smooth skin, leaving a faint pink line against her pulse. She held her bound wrist up between them, turning it slowly so he could see how perfectly the knot sat.
"See? Secure. Unbreakable unless you know the trick." Her voice dropped to a husky whisper. "Imagine tying something softer. Something that squirms and moans when you pull it just right."
Kai's breath hitched. His cock twitched visibly, the thick head nudging against his waistband. A tiny wet spot bloomed on the front of his shorts where he was already leaking.
Lila's pussy clenched hard at the sight, a fresh rush of slick heat soaking her panties. She loosened the rope from her wrist and offered it back, fingers lingering on his.
"Try again. Focus."
He tried. Failed. Again and again. Every time his eyes drifted—to her glistening cleavage, to the way her shorts rode up and pressed against her pussy, to the ass that had been haunting him for years. Sweat poured down her back, turning the white tank nearly transparent. Her nipples were diamond-hard, begging.
Kai's phone buzzed loudly on the cockpit bench.
He yanked it out. "Dad."
Lila's lips curved. "Answer it."
He put it on speaker. Rick's voice boomed out, gruff and impatient.
"Kai, you better be out there practicing those knots like I told you. Weekend's two days away and I'm not letting my son look like some useless dock rat in front of the whole club. You embarrass me and you'll be swimming home—got it?"
Kai's knuckles went white around the rope. "Yeah, Dad. I'm practicing right now. With Mom."
"Good. Lila knows her shit. Listen to her. And keep your damn head in the game—no daydreaming." The line went dead.
Kai stared at the phone, chest heaving. The rope trembled in his grip. "I can't," he muttered, voice raw. "I can't fucking focus when you're standing there looking like that. All I can think about is—"
He cut himself off, teeth gritted, erection throbbing so hard it looked painful.
Lila stepped in until her breasts nearly brushed his chest. She could feel the heat rolling off him, smell the clean musk of his sweat and the sea. Her own pussy was soaked, aching.
"Like what, Kai?" she asked softly, tilting her head. The rope hung forgotten between them. "Tell me what you're thinking about when you look at me."
His eyes burned into hers—desperate, guilty, starving. For a second it looked like he might break. Might admit he wanted to tie her wrists to the railing and fuck her right there on the deck while the boat rocked beneath them.
But he only swallowed hard and looked away.
Lila's smile turned wicked, full of dark promise.
"Tomorrow night," she said, voice low and velvet. "Same time." She reached down, bold and deliberate, and wrapped her fingers around the thick bulge in his shorts. One slow, firm stroke from base to head—enough to make him groan out loud. "If you can't concentrate… maybe we'll have to find a way to fix that."
She turned and walked down the dock, hips swaying, the rope still coiled in her hand and the image of it wrapped around her wrist burned into his brain.
Kai stood frozen on the deck, cock aching, heart slamming, already counting the hours until those restless hands finally got what they wanted.
