Chapter 4: Sundress
The morning sun on the pool deck was a war crime. It hammered through Agatha’s sunglasses, each gleam off the turquoise water a tiny, malicious dagger aimed at her temple. The cacophony was a physical layer—shrieks from the pool, the thump of terrible pop music, the relentless scrape of lounge chairs on wet concrete.
“Vitamin D!” Wanda chirped, slathering sunscreen on her shoulders with the gusto of a painter priming a masterpiece. “And people-watching! This is where the magic happens, Agatha. Look at all these… possibilities!”
Agatha, lying rigid on a lounger in a wide-brimmed hat and a black cover-up, sipped tepid water through a straw. Her stomach rolled with the gentle sway of the ship. The memory of the previous night was a low, persistent throb, equal parts shame and a dark, unsated hunger. She had lost control. She had come apart, loudly, on Rio’s mouth. The taste of her own climax, fed back to her on Rio’s tongue, was a phantom flavor. “The only magic here is the illusion that this isn’t a petri dish of human folly,” she muttered.
“You’re just hungover. You need a proper drink. Hair of the dog!” Wanda declared, springing up. “I’m getting us cocktails. Something fruity with an umbrella. You stay right there and try to look approachable.”
“I’d rather look deceased.”
“Halfway there!” Wanda skipped off toward the bustling bar, weaving through a maze of oiled limbs and pool noodles.
Alone, Agatha let her head loll back. She focused on the hum of the ship’s engines beneath the noise, a steady, mechanical heartbeat. It was calming. Predictable.
The shadow fell over her first, a sudden, cool blotting out of the sun. Then the scent—clean soap, a hint of salt, and underneath, something unmistakably, intimately familiar. Her own scent, from last night.
“You look,” Rio’s voice came, low and amused, “like you’ve been hunted.”
Agatha didn’t open her eyes. “And you look like you’re stalking. It’s unbecoming.”
A tall, frosty glass was pressed into her hand. The cold was a shock. Agatha’s eyes snapped open behind her sunglasses.
Rio stood over her, wearing a simple black one-piece swimsuit that cut across her sharp collarbones. Her hair was down, a tousled auburn cascade. She held an identical drink for herself. Her expression was unreadable behind her own shades, but the smirk was there in the set of her mouth.
“What is this?” Agatha asked, her voice flat.
“Medicine. Gin, lime, soda. Hydration with a purpose.” Rio lowered herself onto the foot of Agatha’s lounger, a casual invasion of space. Her thigh brushed Agatha’s shin.
Agatha lifted the glass. The ice cubes were large, perfectly clear. As she tilted it, one clinked against the side. And there, frozen in its heart, was a perfect, jagged impression. A dental cast. The unmistakable pattern of her own upper teeth from the bite she’d delivered in the stairwell, and again, harder, into Rio’s inner thigh last night as she came.
Her breath caught. She stared at the frozen artifact, a monument to her own savagery, bobbing innocently in the pale liquid.
Rio took a slow sip from her own glass, the ice in hers clinking normally. “I had a word with the bartender. He’s an artist with a mold. Useful skill.”
“You’re insane.” The words were barely a whisper.
“I’m thorough.” Rio leaned closer, her voice dropping so only Agatha could hear. “You marked me. I’m just… commemorating it. A reminder. For both of us.”
The heat that flooded Agatha was not from the sun. It was a vicious, clawing thing, equal parts fury and a dizzying, terrifying arousal. This wasn’t submission. This was something else—a relentless mirror being held up to her own darkest impulses. “You think this is a game.”
“Isn’t it?” Rio’s smile was all teeth. “You make the rules. I find the loopholes. You told me not to interrupt you in public. I’m not. I’m bringing you a drink. That’s polite.”
Wanda was weaving her way back, two lurid pink drinks in hand, her face a cartoon of delight at seeing Agatha “mingling.”
“Get out,” Agatha hissed.
“Meet me,” Rio countered, her tone shifting, losing its edge for a raw second. “Deck seven. The forward observation lounge. It’s empty until noon. Or don’t. But I’ll be there. Watching the wake. Thinking about the weight of that book.”
She stood up in one fluid motion, her drink in hand, and melted back into the crowd just as Wanda arrived.
“Who was that?” Wanda breathed, handing Agatha a sickly-sweet concoction. “She was stunning. You know her! Was that the panties woman?”
“The ‘panties woman’ is a sociopath with a freezer,” Agatha said, staring at the ice cube in her gin. She brought the glass to her lips and drank deeply, letting the cold, bitter liquid and the frozen imprint of her violence wash down her throat.
The forward observation lounge was a tomb of quiet. Located at the ship’s bow, it was all empty plush chairs and panoramic windows showing an endless expanse of churning, blue-white wake against a deep azure sea. The hum here was deeper, the ship’s engines a distant thrum.
Rio stood at the window, a silhouette against the blinding ocean light. She didn’t turn as Agatha entered.
Agatha closed the heavy door behind her. The latch clicked with finality. She walked across the silent carpet until she stood beside Rio, both of them looking out at the relentless, spreading V of foam.
“You wanted an audience,” Agatha said. “You have one. Speak.”
Rio finally turned. She’d taken off her sunglasses. The marks of sleeplessness were under her eyes, but her gaze was clear, intense. “You liked it,” she said simply. “You liked losing control. It scared you. It fucked you up. But you liked it.”
Agatha’s hand itched to strike. She kept it at her side. “Your analysis is juvenile.”
“Is it?” Rio stepped closer. “You came so hard you saw stars. You screamed. You bit me hard enough to break the skin. I have the bruise. I have the mold.” She reached out, her fingers hovering near Agatha’s jaw, not touching. “You’re the most controlled person I’ve ever met. And I unmade you in ten minutes. That’s not a victory for you. It’s a discovery.”
“You’re a discovery of profound annoyance.”
Rio laughed, a short, sharp sound. “Yeah. I am.” Her smile faded. “Tell me to leave you alone. Mean it. And I will. I’ll go back to my cabin and I’ll watch terrible movies and I won’t look for you again.”
The challenge hung in the sterile, air-conditioned air. The truth was a stone in Agatha’s gut. She couldn’t say it. The silence stretched, filled only by the muffled rush of water far below.
Rio’s expression shifted, softened into something like understanding. “Yeah,” she whispered. “That’s what I thought.”
This time, when she closed the distance, it wasn’t an attack. It was a convergence. Her mouth found Agatha’s, and the kiss was nothing like before. It was deep, searching, hungry without being frantic. Agatha’s hands came up, tangling in Rio’s thick hair, not to control, but to hold on. The taste of gin and lime was on both their tongues.
Rio walked her backward until her knees hit a low, wide sofa beneath the window. They sank onto it in a tangle of limbs, the immense sea scrolling past them like a private film. Rio was on top, her weight pressing Agatha into the soft cushions, but it didn’t feel like domination. It felt like immersion.
She kissed down Agatha’s throat, her hands pushing the cover-up off her shoulders. “Tell me what you want,” Rio murmured against her clavicle.
“I want you to shut up,” Agatha gasped, but her hips arched up, seeking friction.
Rio obliged. Her mouth was devastatingly focused. She peeled Agatha out of her simple black bathing suit with a ruthless efficiency, then sat back on her heels, just looking. The sunlight streamed over Agatha’s naked body, pale against the dark upholstery. “Christ, you’re beautiful,” Rio breathed, and the awe in her voice was its own kind of undoing.
She didn’t ask. She lowered her head between Agatha’s thighs and took her with a knowing, relentless mouth. This was not the desperate service of the night before. This was a feast. Rio licked and sucked with a focused precision that stole the breath from Agatha’s lungs. She used her tongue in slow, firm circles, then dipped it inside, fucking her with it, before returning to her clit with a suction that made Agatha’s vision pulse.
“Fuck,” Agatha choked out, her fingers scrambling against the sofa fabric. “Right there. Don’t stop.”
Rio moaned in response, the vibration a direct line to Agatha’s core. She added a finger, sliding it deep, curling it just so. Then another. The stretch was exquisite, the fullness perfect. Rio fucked her with her hand while her mouth never left her clit, a devastating, synchronous rhythm.
Agatha felt the coil snap. Her orgasm tore through her without preamble, a silent, breathtaking seizure. Her body locked, her back bowing off the couch, a strangled cry the only sound as wave after wave of pure, white-hot sensation blazed through her. Rio gentled her mouth but didn’t stop, drawing out the pulses until Agatha was a trembling, oversensitive mess, pushing weakly at her head.
Rio crawled back up her body, her face wet, her eyes dark. She kissed Agatha, letting her taste herself. Agatha’s hands fumbled with the straps of Rio’s swimsuit, shoving them down, needing to feel skin.
Once Rio was bare, Agatha rolled them. Now she was on top, straddling Rio’s hips, the vista of ocean behind her. She could see the faint, perfect bruise on Rio’s inner thigh, a twin to the ice cube. She ran a thumb over it, and Rio shuddered.
“You want to watch?” Agatha asked, her voice ragged.
“Yes.”
Agatha reached between her own legs, gathering the slickness there, then guided Rio’s hand down. “Then watch this.”
She positioned Rio’s long fingers against her own soaked cunt, then sank down onto them, taking them deep inside herself with a low, guttural moan. She began to ride Rio’s hand, setting a slow, grinding pace. Rio’s other hand came up to grip Agatha’s hip, her thumb pressing into the bone.
“You feel that?” Agatha panted, rising and falling, taking Rio’s fingers to the hilt. “That’s you. Inside me. That’s where you belong. Not in my lap with parlor tricks. Here.”
She leaned forward, bracing her hands on the sofa back, her mouth near Rio’s ear. “Come for me. Just from this. From watching me use you.”
Rio’s breath was coming in harsh gasps. Her eyes were glued to where their bodies joined, watching her own fingers disappear into Agatha’s slick, grasping heat with every downward thrust. The obscene, wet sounds filled the quiet lounge. Agatha felt the tension coiling in Rio’s abdomen, saw her teeth sink into her own lower lip.
“That’s it,” Agatha whispered, speeding her pace, driving herself toward another peak on Rio’s hand. “You’re mine. You come when I tell you to. Now.”
A broken cry ripped from Rio’s throat. Her back arched, her body seizing as orgasm slammed into her, triggered by the sight, the feel, the sheer filthy truth of being used so perfectly. Her fingers curled inside Agatha, the involuntary spasm tipping Agatha over the edge a second later. This climax was deeper, a rolling, consuming thing that left her weak and shuddering, collapsed on top of Rio’s heaving chest.
For long minutes, there was only the sound of their breathing and the distant sea.
Rio’s hand, still tucked between Agatha’s thighs, gently withdrew. She wrapped both arms around Agatha, holding her close in the sunlight. It was unnervingly tender.
Agatha’s mind, clearing from the haze, began its cold, analytical work. This was a problem. This was a catastrophic complication. The lines were not just blurred; they were erased.
She pushed herself up, disentangling their limbs. She found her suit, her cover-up, dressing with her back to Rio. The silence now was heavy, awkward.
“Agatha—” Rio began, sitting up.
“Don’t,” Agatha cut her off. She fastened her hat, her movements sharp. “This was a mistake.”
“It didn’t feel like a mistake.”
“Your emotional barometer is broken.” Agatha turned. Rio looked heartbreakingly young, sitting naked on the rumpled sofa, marked and claimed. “The cruise ends in three days. Whatever this is, it ends with it.”
She walked to the door. Her legs felt unsteady.
“You’re scared,” Rio said to her back, not accusingly. A simple statement.
Agatha didn’t deny it. She opened the door and stepped back into the roar of the ship, leaving the quiet, sun-drenched ruin of the observation lounge behind.
