Chapter 17: Hydrophilic
The steam in the bathroom was thick enough to taste, damp and metallic on the tongue. Vy leaned against the cool, slick tiles, her body still trembling with aftershocks. Katy stood under the spray, head back, eyes closed, water sluicing down the sharp planes of her face and body, washing away the evidence of their first frantic round. The echoes of Vy’s screams seemed to linger in the humid air, absorbed by the thrum of the fan.
Katy turned off the water. The sudden silence was a physical thing, broken only by the drip from the showerhead and their ragged breathing.
“Again,” Katy said, her voice a low rasp. It wasn’t a question.
She reached out, her wet hand finding Vy’s wrist. Her grip was firm, not painful, but utterly assured. She pulled Vy back under the still-warm spray, her other hand cupping the back of Vy’s neck. “I need to feel you come apart again. I need to hear it.”
Vy’s exhaustion was a distant hum beneath the immediate, electric current Katy’s touch ignited. She nodded, her forehead resting against Katy’s collarbone. The water plastered her long black hair to her back, streamed down her face.
Katy’s mouth found hers, a deep, possessive kiss that tasted of chlorine and themselves. Her hands slid down Vy’s sides, over her hips, gripping the firm flesh of her ass. She lifted her, easily, pushing her back against the tiles. Vy’s legs wrapped around Katy’s waist, anchoring herself.
“Good,” Katy breathed against her lips. Her fingers traced the slick seam of Vy’s body, found her still swollen and sensitive from before. She pushed two fingers inside without preamble, a smooth, deep invasion that made Vy gasp into her mouth.
“Count,” Katy commanded, her dark eyes holding Vy’s.
“One… two…” Vy choked out, the words dissolving into a moan as Katy began to move.
It was slower this time, more deliberate. Katy fucked her with her fingers in a steady, relentless rhythm, her palm grinding against Vy’s clit with each thrust. The wet, rhythmic sound was obscenely loud in the small stall. Vy’s head tipped back, hitting the tile with a soft thud. Her nails dug into Katy’s shoulders.
“Look at me,” Katy growled.
Vy forced her eyes open. Katy’s expression was fierce, focused, a conqueror surveying captured territory. She added a third finger, the stretch intense, breathtaking. Vy cried out, a sharp, broken sound.
“Count it.”
“Three!” Vy gasped. The fullness was overwhelming, a perfect, burning pressure. Katy curled her fingers, scraping over that exquisite, hidden spot deep inside. Vy’s vision sparked white at the edges. Her thighs clamped around Katy’s wrist, her entire body tightening like a coiled spring.
“Come on, baobei,” Katy whispered, her voice harsh with strain. “Let me feel you.”
She increased the pace, her fingers pistoning in and out with wet, slapping sounds. The angle was ruthless, her thumb circling Vy’s clit in tight, frantic circles. The sensations fused into a single, intolerable point of pleasure. Vy came with a shattered cry, her body convulsing around Katy’s thrusting hand, wave after wave of electric heat tearing through her. Katy held her through it, never stopping, milking the orgasm until Vy was sobbing, oversensitive and boneless.
Only then did she slowly, gently, withdraw her fingers. She held Vy up, pressing gentle kisses to her shoulder, her jaw, her closed eyelids. “One more,” she murmured, but her voice was softer now, laced with something akin to wonder.
They stumbled out of the shower, dripping, their feet slapping on the linoleum. Katy grabbed a rough white towel and began to dry Vy with a surprising tenderness, patting the moisture from her skin. But the look in her eyes hadn’t softened. It had merely changed, banked coals ready to flame again.
In the dim light of Katy’s room, with the chaotic poetry and economics graphs watching from the walls, she laid Vy on the rumpled bed. The air was cool on Vy’s heated skin. Katy stood over her for a moment, just looking, water beading on her skin and dripping onto the floorboards.
Then she climbed over her, her knees bracketing Vy’s hips. She didn’t kiss her. She just stared down, her gaze burning.
“You are the most exquisite algorithm I’ve ever encountered,” Katy said, her voice quiet. “Every input. Every output. Perfectly predictable in your chaos.”
She leaned down, her hair dripping onto Vy’s chest. Her mouth closed over Vy’s nipple, sucking hard, her tongue lashing the pebbled peak. Vy arched off the bed, a fresh jolt of desire spearing through her exhaustion. Katy’s hand slid between her own legs, and the wet sound of her touching herself was blatant, crude.
“I’m going to fuck you,” Katy stated, lifting her head. “And you’re going to watch me.”
She shifted back, positioning herself. Vy saw the blunt head of the strap-on, dark against Katy’s skin. They hadn’t used it since Osaka. The sight of it now, in this context of reclamation and fierce privacy, sent a new, deep thrill through Vy.
Katy guided it, pressing the tip against Vy’s entrance. She was still loose, wet, open from the last two rounds. But the size, the solidity, was different. A full, stretching pressure.
“Look at me,” Katy repeated, her voice guttural.
Vy’s eyes locked on hers. Katy pushed forward, a slow, inexorable invasion. Vy gasped, her mouth falling open as she was filled, utterly and completely. Katy sank deeper, deeper, until their bodies were flush, the harness a firm pressure against Vy’s clit.
“Fuck,” Vy whispered, the word dragged from the very core of her.
Katy began to move. It was a deep, rolling rhythm, each thrust pressing the air from Vy’s lungs. The sound of skin against skin, the creak of the bed, Katy’s ragged breaths, filled the room. Vy’s hands scrambled for purchase, finally gripping the metal bars of the headboard.
“Is this what you need?” Katy panted, her hips snapping forward. “After his eyes? After his fucking whispers?This.Me. Filling you up so there’s no room for anything else.”
“Yes,” Vy hissed, her heels digging into the small of Katy’s back. “Just you. Only you.”
Katy’s pace quickened, became punishing. Her thrusts were hard, deep, each one jolting Vy up the bed. The pleasure was a crescendo, a brutal, building wave. Vy could feel the harness grinding against her, the double stimulation pushing her toward the edge with terrifying speed.
“I can feel you,” Katy groaned, her forehead dropping to Vy’s shoulder. “I can feel you clamping down on me. You’re so fucking tight. Even now. Greedy for it.”
She bit down on Vy’s shoulder, not hard enough to break skin, but a sharp, possessive sting. The pain fragmented the pleasure, scattered it like shards of glass through Vy’s nerves, before coalescing into something even sharper, brighter.
“Katy… I’m gonna…”
“Come,” Katy ordered, her voice breaking on the word. “Come all over this cock. Let me feel you lose it.”
The orgasm detonated, a silent, shattering explosion that ripped a raw scream from Vy’s throat. Her body seized, clamping rhythmically around the length inside her, her vision dissolving into static. Katy fucked her through it, her own movements becoming erratic, frantic, until with a final, deep grind and a choked cry, she stilled, her body trembling violently against Vy’s.
For long minutes, there was only the sound of their struggling breaths. Katy finally shifted, withdrawing with a soft, wet sound. She collapsed beside Vy, one arm thrown possessively across her stomach. The strap-on lay between them, a stark, rubbery evidence of what had just happened.
The high, brutal crest of sensation began to recede, leaving a deep, floaty calm in its wake. Vy turned her head on the pillow. Katy was already looking at her, her eyes dark, unreadable.
“The trace,” Vy said quietly, her voice hoarse. “Colin Marsh. What do we do?”
Katy’s thumb stroked a slow circle on Vy’s damp hipbone. “We do nothing.”
“Nothing?”
“The power is in the reaction. We deny him that.” Katy’s voice was analytical, but her fingers traced a possessive, absent pattern on Vy’s skin. “I’ve already implemented a digital wall. He gets no new data. His access to our feeds is an illusion. He’s shouting into a void.”
“And if he escalates? If he approaches?”
A cold, flat light entered Katy’s eyes. “Then the game changes. Then it ceases to be a digital puzzle and becomes a physical problem. And physical problems have very direct solutions.” She turned onto her side, propping her head on her hand. “But he won’t. He’s a data vampire. He feeds on unseen access. The moment he’s seen, he’s powerless.”
Vy absorbed this. The fear, which had been a constant, low-grade hum, began to quiet. Replaced not by safety, but by a shared, ferocious will. “Our fortress,” she murmured.
“Our fortress,” Katy affirmed. She leaned in and kissed Vy, a soft, closed-mouth press of lips. It was startling in its tenderness after the raw carnality of the last hour. “Get some sleep. We have a problem set due tomorrow.”
Vy blinked. “Economics 248?”
“Mm-hmm. Dynamic optimization. It’s a bitch.” Katy’s lips curved into a faint, real smile. “We’ll solve it in the morning.”
She reached over and flicked off the desk lamp, plunging the room into a deep blue dark, broken only by the faint glow of her laptop’s sleeping light. In the sudden stillness, Vy listened to Katy’s breathing even out beside her. The stalker was a ghost in a machine. The world outside was a set of problems to be optimized. But here, in the tangled sheets that smelled of sex and lavender, with the proof of their shared violence resting between them and Katy’s arm a heavy, protective weight across her waist, Vy understood the new protocol. It wasn’t about hiding.
It was about making their own world so solid, so real, so impenetrably theirs, that nothing else could ever truly breach the walls.
The fortress walls, for the next week, felt reassuringly thick. Vy buried herself in the dynamic optimization problem sets, her coding, and the precise, predictable warmth of Katy’s body each night. The anon.seeker92 profile went dormant. Colin Marsh remained a name without a face, a potential equation left unsolved. Life became a series of closed systems: their room, the library carrel, the tangled sheets of Katy’s bed.
Then, on Friday, the atmosphere shifted.
Vy returned from the statistics lab, her backpack heavy with data printouts. She found Katy standing before the narrow dorm mirror, a critical frown on her face. The room smelled of hair product and a new, expensive perfume, something dark and orchidaceous.
“Hey,” Vy said, dropping her bag. “What’s up?”
Katy turned, and the air left Vy’s lungs. She wore a dress. It wasn’t just a dress. It was a weapon, a declaration, a sin in black fabric. The material was a liquid matte, so tight it seemed painted onto her skin. It plunged in a deep V at the front, cinched at her narrow waist, and clung to the perfect, devastating curve of her hips and ass before ending in a sharp cut high on her thighs. Her legs, sheathed in sheer black stockings with a subtle seam, looked impossibly long.
“I’m going out with Sasha and the econ grad school group,” Katy said, her voice casual as she fastened a thin silver necklace. “Some donor’ cocktail thing at The Liberty. Black tie optional, which is code for ‘look expensive and fuckable.’”
She did a slow spin. The dress back was just a series of intricate straps, a spiderweb against her skin. Vy could only stare. This wasn’t their private Katy. This was a public broadcast, a high-frequency signal of pure, untouchable allure.
“You look…” Vy began, but words failed. Incendiary. Dangerous.
“It’s tight, right?” Katy smirked, smoothing a hand over her stomach. “Good. Let them look. Let them see exactly what they can’t have.” Her eyes met Vy’s in the mirror, glinting with a hard, performative confidence. But beneath it, Vy sensed the same calculation that had traced the stalker’s IP address. This was a move on a different board.
A sharp, hot needle of jealousy pressed beneath Vy’s sternum. It was followed by a dizzying wave of desire so potent it felt like nausea. She wanted to claw the dress off with her teeth. She wanted to hide Katy away forever.
“How late?” Vy asked, her voice strangely thin.
“No idea. Don’t wait up.” Katy leaned down, brushing a kiss against Vy’s temple. Her perfume was overwhelming. “Hold the fortress, baobei.”
Then she was gone, the click of her heels fading down the hallway. The room felt cavernous, cold. Vy sat on the rumpled bed, the optimization problems blurring before her. She imagined the soft murmur of a luxury hotel bar, the clink of crystal, the weight of older, appreciative eyes on the serpentine lines of Katy’s body. The dress would feel like cool water under those gazes. She imagined a hand, not hers, resting on the small of that back, on a strip of bare skin between the straps.
A violent, physical ache seized her. It was a different kind of breach. Not a digital ghost, but the very real, glittering world Katy could step into, a world where Vy was just a freshman hiding in a dorm room. She paced, the silence oppressive. She tried to read a journal article on stochastic models. The words were nonsense.
Her phone buzzed on the desk. A text from an unknown number.
Unknown: That dress is a bit much, even for her. Doesn’t leave much to the imagination. Does it?
The blood drained from Vy’s face, pooling ice-cold in her feet. She stared at the screen. He wasn’t dormant. He was there. He had seen Katy leave. He was watching the fortress walls right now, and he was whispering through a new crack. The jealousy curdled, fused with a terror so pure it was rage.
Vy’s fingers trembled as she typed, not to the unknown number, but to Katy.
Vy: He just texted me. About your dress. He’s here.
The three dots appeared immediately. Then vanished. A full minute passed. The phone rang, Katy’s name flashing. Vy grabbed it.
“Where are you?” Katy’s voice was a whip-crack, all casual pretense gone. The background murmur of the event had vanished; she was somewhere quiet.
“In your room. He said the dress was ‘a bit much.’”
A low, venomous sound came through the line. “The Liberty is twenty minutes away. I’m in the bathroom. Give me ten.” The line went dead.
Vy sat in the dark, watching the door. The high from earlier was gone, replaced by a corrosive dread. She heard the hurried footsteps, the jangle of keys. The door flew open. Katy stood there, backlit by the hallway light, chest heaving. The magnificent dress was now just a costume, her face a mask of furious intent.
She slammed the door, locked it, and strode to her desk. She woke her laptop, her fingers flying across the keyboard. “The text. Show me.”
Vy handed her phone over. Katy read the message, her expression hardening into something frighteningly still. She pulled up a campus map, cross-referencing it with the signal data she’d compiled before. “He’s close. He had to see me leave to text you that. Which means he’s on this floor. Or was.”
She stood abruptly, her eyes scanning the room as if it were a crime scene. Then her gaze landed on Vy, who was shaking, curled on the bed. The technological fury in Katy’s eyes morphed, shifted into something predatorily physical.
“He wants to get a reaction?” Katy’s voice was soft, dangerous. “Let’s give him one he can fucking hear.”
She crossed the room in three strides. She didn’t kiss her. She grabbed the collar of Vy’s t-shirt and yanked her up, then pushed her back down onto the mattress, her body following. The stiff fabric of the luxury dress scraped against Vy’s skin. Katy’s hand shoved between them, gathering the expensive material in a rough fist. With a sharp, tearing sound of fabric and a ping of snapping thread, she ripped the dress open from waist to clavicle.
Vy gasped. Katy’s bare skin, hot and smooth, pressed against her. The ruined dress gaped, exposing a black lace bra. Katy’s mouth crashed down on Vy’s, a hard, punishing kiss. She ground her hips down, the hard line of the chair’s edge in her stocking against Vy’s thigh.
“He thinks he can watch us?” Katy snarled, tearing her mouth away. Her hands went to Vy’s sweatpants, dragging them and her underwear down in one violent motion. “Let him listen. Let him hear what he’s not getting. What he’ll never get.”
She rolled off Vy long enough to shove the torn dress down her own body, kicking it away with a contemptuous flick of her foot. The stockings and heels stayed on. She wrestled with the harness, her movements frantic, jerky with rage. Once it was secured, she didn’t bother with pretense. She coated the length with lube from the bedside drawer, the sound obscene in the tense quiet.
She positioned herself between Vy’s spread legs, one hand pinning Vy’s hip to the bed. Her eyes were black pits in the dim light. “You scream for me,” she commanded, her voice ragged. “You scream until your throat is raw. I want every monster hiding in the walls to know who this cunt belongs to.”
She shoved inside. The thrust was brutal, bottoming out in one deep, savage stroke. Vy cried out, a sharp, involuntary sound torn from her chest. The stretch was intense, a burning fullness that crossed the threshold into perfect, obliterating pain. Katy set a relentless, pounding rhythm, the bed slamming against the wall with each drive of her hips.
The sounds were animalistic: the wet slap of skin, the creaking bedframe, Katy’s guttural grunts, the choked, ragged cries Vy couldn’t suppress. Katy leaned down, her teeth grazing Vy’s earlobe. “Louder,” she hissed, snapping her hips harder. “Let him know his little message just earned you the hardest fuck of your life.”
Vy’s mind shattered. The fear, the jealousy, the violation—all of it was being pounded into a different shape by the relentless piston of Katy’s body. She clutched at Katy’s back, her fingers sliding over sweat-slick skin and the rough straps of the harness. Each deep, driving thrust hit a spot that made lights burst behind her eyelids.
“Katy!” she screamed, her voice breaking. “Don’t stop… please…”
“Whose?” Katy demanded, her rhythm becoming erratic, her control fraying.
“Yours! Yours, god, fuck, only yours!”
The affirmation seemed to detonate inside Katy. With a raw, torn shout, she buried herself to the hilt and held there, her body rigid. Vy felt the convulsive pulses through the harness, a violent, mimicked climax. It triggered her own. Her vision whited out as her body clamped down, a series of seizing, electrical waves that felt less like pleasure and more like exorcism.
Katy collapsed atop her, their sweat mingling, their hearts hammering against each other’s ribs in a syncopated riot. The only sound was their ragged, starving breath. The room felt charged, vibrating with the echo of violence they’d just wrought together.
After a long time, Katy shifted, withdrawing. She disposed of the harness, then gathered Vy against her, her touch now shockingly gentle. She pulled the comforter over them. In the dark, she found Vy’s hand, lacing their fingers together. Her grip was tight, almost painful.
“The dress was a test,” Katy whispered into Vy’s hair, her voice hoarse. “For him. I wanted to draw him out. To make him show himself.” She pressed her lips to Vy’s temple. “I’m sorry. I used us as bait.”
Vy absorbed this. The strategic mind, never resting. “Did it work?”
Katy’s silence was heavy. “He didn’t approach. He just… watched. And texted.” She let out a long, shaky breath. “But he heard us. He knows the cost of touching what’s mine.”
Outside, the old campus was still. Somewhere, perhaps in a room down the hall or hiding behind a proxy server, a boy stared at a silent phone. Inside the fortress, the walls were scarred, and humming. They were also, for now, sealed. Two bodies held the breach, not with silence, but with a sound he would never forget.
