23-year-old Jason signs up for a paid scientific research study where he will be a test subject for a machine his friend, 25-year-old Simon, built. He wouldn’t have to do anything but sit in the machine and let it work on his body. He would be fed, bathed, and housed for the duration of the study, and—depending on how many hours he completed— Jason would receive up to 3000 dollars. The catch; Simon built a tickling/milking machine, one that was specifically calibrated to the most sensitive parts of Jason’s body (a little detail he’d mischievously left out) This study leads to a confession and acceptance of love. Along with many hours of ticklish, torturous pleasure.

Chapter 24: The Laundry Revelation

The descent from the sun-warmed bedroom to the basement laundry room felt like moving from a living organism into a machine. Simon’s building was old, and the laundry room was a relic of utilitarian design: white subway tiles, fluorescent lights that buzzed faintly overhead, a concrete floor stained with decades of bleach spills. The air was warm and thick with the scent of cheap detergent and fabric softener, undercut by the mineral tang of damp concrete. A single, high window was half-blocked by a limp, yellowed curtain, letting in a watery suggestion of the fading day.

Jason followed Simon, arms laden with the bundled, incriminating sheets. The cotton still carried the warmth of their bodies, a private scent lost in the chemical wash of the room.

“Home sweet home,” Simon said, his voice echoing slightly. He dumped his load into one of two stainless steel washing machines. The lid closed with a definitive, heavy clang.

“It’s very… antiseptic,” Jason said, setting his bundle on a folding table. The surface was cool and slightly sticky.

“Efficient. Controllable variables.” Simon was already in motion, sorting with brisk precision—lights, darks, the mattress cover they’d finally excavated from the hall closet, a crumpled, crinkly blue barrier. “Temperature, cycle duration, spin speed. Everything has a optimal setting.”

Jason watched him, this familiar rhythm of Simon’s mind applied to laundry. It was comforting. He picked up a discarded t-shirt from the top of the pile, started folding it just to have something to do with his hands.

Simon’s phone, resting on the dryer, lit up with a muffled buzz.

They both glanced at it. It was dark, silent.

A second later, Jason’s phone, in his back pocket, vibrated against him. He flinched, a Pavlovian flush already rising on his neck. He pulled it out slowly, like it might be wired to explode.

The screen glowed in the sterile light.

Mom: Did you find the cover? It’s in the hall closet.

Simon, peering over from where he was measuring detergent, read the text. His lips twitched. He straightened up, adopting a posture of mock academic solemnity, clearing his throat.

“The maternal subject has issued a follow-up inquiry,” he announced, his voice taking on that faint, lecturing tone. “Pertaining to the location and deployment of the previously referenced hygienic barrier. Hypothesis: she remains invested in the preservation of the mattress’s structural and warranty integrity.”

Jason stared at him, the heat in his face battling a helpless surge of affection. “You’re the worst.”

“I’m providing a real-time analysis of an ongoing social dataset.” Simon’s eyes glittered. “The data point is clear. The cover has been located and deployed. Should we respond with confirmation? Or let the unknown linger, introducing a variable of suspense into her evening?”

That was it. With a strangled laugh, Jason dropped the shirt and launched himself at Simon.

He wasn’t a fighter, but he was fast, and Simon was caught off-guard, his scientific detachment shattering into a yelp of surprise as Jason’s momentum carried them both onto the small, worn couch shoved against the far wall. It was a lumpy, vinyl thing, donated by a former tenant and smelling vaguely of dust and lavender dryer sheets.

Jason dug his fingers into Simon’s sides.

The effect was instantaneous.

Simon gasped, then a sharp, unguarded laugh burst out of him. He writhed, trying to curl away, but Jason had him pinned, leaning his weight into him. “Variables, huh?” Jason teased, finding a spot under Simon’s ribcage that made him jerk violently.

“J-Jason! Stop—that’s not—ah!” Simon’s laughter was breathless, ragged, completely unlike his usual controlled chuckles. It was a desperate, joyful sound. He grabbed at Jason’s wrists, but his grip was weak, compromised by the convulsions shaking his frame. “Unfair! Unethical! Cease!”

“You started it with the commentary.” Jason relented, just for a second, hovering over him. Simon’s face was flushed, his dark hair wild against the ugly green vinyl, his chest heaving. His sharp blue eyes were wide, vulnerable, glistening with mirth and something else.

In that suspended moment, the hum of the fluorescent lights was the only sound. The smell of laundry soap was everywhere. Simon’s breath warmed Jason’s lips.

“You’re ticklish,” Jason whispered, the discovery feeling immense.

“A irrelevant biological vulnerability,” Simon breathed back, his voice shaky. His hands loosened their grip on Jason’s wrists, sliding up to his shoulders.

Jason closed the last inch between them and kissed him.

It was different from the kisses in the bedroom—softer, slower, punctuated by the occasional aftershock of a laugh trembling through Simon’s body. Jason could taste the residual surprise on his lips. He sank into the kiss, into the unfamiliar give of the crappy couch, into the way Simon’s hands came up to cradle his face, thumbs stroking his jawline.

When they finally broke apart, Simon’s expression was wonderstruck. He looked dazed. “Your mother’s doting,” he murmured, his voice rough, “is now a permanent variable in our relationship equation. A constant. It updates in real-time.”

Jason groaned, letting his forehead thump against Simon’s shoulder. But he was smiling so wide his cheeks ached. “She’s gonna ask for receipts next. Proof of purchase for the condoms.”

Simon’s body shook beneath him with silent laughter. His fingers trailed up and down Jason’s spine. “I’ll generate a graph. It’ll look very impressive.”

They lay there for a while, tangled on the uncomfortable couch, listening to the washer begin its churning cycle next door. The domestic noise was a grounding drumbeat. Jason nuzzled into the crook of Simon’s neck, breathing him in—detergent, sweat, him.

“You never told me you were ticklish,” Jason said quietly.

Simon went still for a fraction of a second. His hand paused on Jason’s back. “You never asked.”

“After all that time with your machine? You knowing every single one of my spots?” Jason lifted his head to look at him. The fluorescent light was unforgiving, highlighting the faint shadows under Simon’s eyes, the cautious set of his mouth. “It never occurred to you to mention it?”

Simon looked away, his gaze fixed on the ceiling tiles. “It wasn’t relevant to the study parameters,” he said, but the words were flat, a recitation. He swallowed. “And it’s… a significant vulnerability. More than most. It’s a complete systems override. You witnessed it.” He glanced back, a flicker of that old, guarded intensity returning. “Knowledge like that is power. I designed the study to have power over you. Voluntarily given, but power nonetheless. Offering you the same knowledge… it felt like an imbalance I wasn’t ready to correct.”

The honesty of it landed in the quiet room, heavier than the thump of the washing machine. Jason thought of the hours spent in helpless, shuddering sensation under Simon’s machine, under his later, careful hands. The total surrender. He’d given that. Simon had catalogued it, learned it, loved him through it.

And had kept his own weakness a secret.

Jason lowered his head and pressed a soft, deliberate kiss to the exact spot on Simon’s rib cage that had made him shriek. He felt Simon’s abdominal muscles clench, heard the sharp intake of breath.

“Consider the equation balanced,” Jason whispered against his skin.

A shudder ran through Simon. Not a ticklish one, but something deeper. His arms tightened around Jason, holding him close. The dryer kicked on with a rumble, a wave of heat washing over them. They stayed there, in their hidden, sterile little chamber, as the machines worked and the world above them carried on, unaware of the quiet, monumental trade that had just occurred.

They stayed there, in their hidden, sterile little chamber, as the machines worked and the world above them carried on, unaware of the quiet, monumental trade that had just occurred. Simon finally stirred, his voice a warm rumble against Jason’s ear. “The wash cycle is almost complete. We should initiate the drying protocol before someone downstairs complains about the thumping.” Jason groaned but rolled off, his body missing the heat immediately. They folded themselves back into the mundanity, transferring damp clothes with shoulders brushing, a silent conversation in every glance.

The next few days were a whirlwind.

Simon vanished into long shifts at his internship, returning with the faint, sharp smell of solder and sterilized metal on his clothes. Jason juggled two different part-time gigs—one at a bookstore that smelled of old paper and dust, the other behind a coffee counter that left his skin perpetually smelling of bitter espresso grounds. He also tried to impose order on his new space, which mostly meant shifting piles of clothes from the floor to a chair and then back again. Texts between them were functional, flashed across screens during stolen minutes: Running late. Can you grab milk? Lab ran over. Don’t wait up. The sheer normalcy of it was a novel and exhausting script.

However, they always reconnected in bed.

No matter how late, the world narrowed to the king-sized mattress, now faithfully clad in its crinkly blue armor. They would fall into it, often already half-asleep, still smelling of their separate days. Simon’s hands were always cold from the lab’s climate control. Jason’s shoulders were knotted from lifting boxes of books or constant tamping. They didn’t talk much. Words were too heavy. Instead, Simon would find a tight muscle in Jason’s back and press his thumb into it with precise, unwavering pressure until Jason melted into a sigh. Jason would curl against Simon’s chest, listening to his heartbeat slow from the day’s frantic rhythm, anchoring them both.

One such night, well past one, Jason was already adrift when he felt Simon shift. A seam of light from the streetlamp outside cut across the room, illuminating the focused plane of Simon’s face. He was propped on an elbow, just watching. “What?” Jason mumbled, voice thick with sleep.

“You have a freckle,” Simon whispered, his fingertip tracing a spot just below Jason’s navel, “right here. I missed it on my initial maps.”

Jason shivered, the touch a bright point in his drowsiness. “Your maps have gaps, genius.” He captured Simon’s wandering hand, lacing their fingers together. “Big, glaring omissions.”

Simon’s smile was a faint curve in the dim light. He brought their joined hands to his lips, kissing Jason’s knuckles. “The research is ongoing. It requires perpetual, hands-on data collection.” He leaned down, his next words a breath against Jason’s mouth. “Subject compliance remains exceptionally high.” The kiss that followed was slow, deep, and tasted like shared toothpaste and the promise of a tomorrow that, for the first time, didn’t feel like it was rushing away from them.

The kiss that followed was slow, deep, and tasted like shared toothpaste and the promise of a tomorrow that, for the first time, didn’t feel like it was rushing away from them. Sleep pulled them under not long after, a dense and dreamless void where the only constants were the touch of Simon’s ankle hooked over his and the steady, trusted rhythm of his breath.

On the weekend, Jason wakes to Simon’s weight on top of him.

The man is already awake and plants little kisses and licks to his tummy, a trail of warm, damp points that make Jason’s muscles flutter and contract in the dawn light. He’s half-hard, sleep-soft and pliant, and a groan vibrates in his chest. “Time’s it?” he mumbled, his voice shredded with sleep.

“Early.” Simon’s answer was a puff of air against the sensitive skin just below his navel. His hands slid under Jason’s hips, lifting him slightly, insistently. “No schedules. No machines. No maternal surveillance texts.” He nipped gently, and Jason jerked, a laugh catching in his throat. “Just this variable. My hands. My mouth. Your responses.”

Jason’s head fell back against the pillow. He carded his fingers through Simon’s messy dark hair, not to guide, just to feel the texture. “Your research is insatiable.”

“The initial findings were compelling.” Simon’s tongue traced a slow circle. “They demand replication.” He looked up, his sharp blue eyes clear and focused, but with a softness at the edges reserved only for these quiet, stolen hours. “Tell me to stop.”

Jason’s breath hitched. He knew what Simon was really asking. It wasn’t about this moment, here in the golden Saturday quiet. It was about the machine, the study, the power dynamic Simon had meticulously built and then carefully dismantled. It was about trust, offered back to him now, raw and unconditional.

“Don’t you dare stop,” Jason whispered.

A shudder ran through Simon, a visible release of tension Jason hadn’t fully registered was there. Then he bent his head, his touch shifting from teasing exploration to deliberate, overwhelming focus. Jason’s back arched off the mattress, a choked sound escaping him. He fisted the sheets, then Simon’s hair, his world narrowing to the point of contact, the building, intolerable pressure, the complete surrender of control he now gave freely.

After, shaking and boneless, Jason pulled him up. He kissed Simon’s slack, wet mouth, tasting himself, a tang of salt and intimacy. They lay facing each other, noses almost touching, legs tangled. The sun was properly up now, painting the room in bold, bright stripes.

“You know,” Jason said, tracing the line of Simon’s eyebrow with his thumb. “For a genius, you missed a pretty major flaw in your own study design.”

Simon’s eyes, heavy-lidded and sated, sharpened just a fraction. “Explain.”

“You studied my physical reactions. Catalogued the data. You even,” Jason poked Simon’s side, making him twitch, “identified a reciprocal vulnerability. But you never accounted for the observer effect.”

Simon blinked. “The act of observation altering the phenomenon being studied.”

“Yeah.” Jason’s thumb moved to Simon’s lower lip. “You watched me fall apart for hours. Days. You thought you were just collecting data. But you were in the system the whole time, Simon. You were the biggest variable. You changed the experiment by being in the room. And the experiment changed you.”

Simon was utterly still. His gaze searched Jason’s face, flickering across his features as if seeing a new piece of code, a unexpected but elegant solution. A slow, deep blush crept up his neck. He looked exposed, more than he had on the laundry room couch.

“The emotional corruption of the data set,” he finally said, his voice rough.

“No.” Jason shook his head, smiling. “The point of the data set. You just didn’t know it yet.”

Simon hid his face in the crook of Jason’s neck. His breath was hot and uneven. “I was so scared,” he confessed, the words muffled by skin. “The entire time. That you’d see it. That you’d know what the machine really was. A confession I was too afraid to make with words. It was cowardice, dressed up as science.”

Jason held him tighter. “It was the most you thing you’ve ever done. Building a whole complicated machine just to tell me you loved me.” He felt Simon’s arms lock around him, a desperate, grateful pressure. “Next time, maybe try a note. Or, I don’t know, flowers.”

Simon laughed, a wet, broken sound against his skin. “Flowers lack precision. They die. My data is permanent.” He lifted his head, his eyes red-rimmed but clear. “I have terabytes of it. Graphs of your galvanic skin response. Spectral analyses of your vocalizations.”

“You’re such a romantic,” Jason deadpanned.

“I am,” Simon insisted, utterly serious. “I have proof.”

Simon’s declaration hung in the sunlit air between them, a fragile, technical boast. Jason stared at his face, at the absolute earnestness there, and felt something huge and warm crack open inside his ribcage. He couldn’t speak. He just kissed him, a slow, deep press of lips that was an answer in itself.

When they parted, Simon’s eyes were darker, his breathing uneven. The analytical edge had softened into something raw and satisfied. Jason traced the line of his jaw, his thumb scraping over the faint stubble there.

“Proof,” Jason finally said, his voice rough. “Right. Your terabytes of my tortured giggling.”

“It’s more than that,” Simon insisted, but he was leaning into the touch, a silent request for more. “It’s a quantifiable record of your trust. Your surrender. It’s the most valuable dataset in the world.”

Jason smiled, a real one that made his eyes crinkle. “You’re a complete weirdo.” He shifted, rolling Simon onto his back and settling over him, their bodies slotting together with a familiar, heat-seeking alignment. The crinkle of the mattress cover was a quiet, ridiculous soundtrack. “My weirdo.”

Simon’s hands came up to rest on Jason’s hips, his thumbs pressing into the pronounced bone there. His gaze traveled over Jason’s face, down his throat, over his shoulders, as if committing this new, unguarded version to memory. The morning light caught in the dust motes drifting around them.

A comfortable, heavy silence stretched, filled only with their breathing and the distant sound of traffic. Jason lowered his head, nuzzling into Simon’s neck, inhaling the clean, sleep-warm scent of him. He let his weight settle fully, a grounding pressure.

Simon’s fingers drifted, skating down the sensitive path along Jason’s spine, then back up. It wasn’t a tickle. It was a re-mapping, a possessive re-acquaintance. Jason shivered, a full-body ripple of pleasure.

“Your autonomic responses are still perfectly synchronized to my touch,” Simon murmured, his scientist’s voice blending with something softer, more awed. “Even without the sensors. The data was predictive.”

“Told you you were a good researcher,” Jason mumbled into his skin. He rocked his hips, just once, a slow, deliberate friction that made them both gasp. A current of pure, lazy desire, banked from earlier, began to glow again. He lifted his head, meeting Simon’s eyes. The blue was almost black now, pupils blown wide with want.

Jason grinned, a flash of mischief. He dipped his head and whispered the words directly into Simon’s ear, his breath hot.

“So, when’s the next chair session? My balls are feeling kinda heavy. And I feel like being observed.”

Simon froze.

Every muscle in his body went taut beneath Jason. His breath hitched, a sharp, audible intake. The hands on Jason’s hips stilled. For a terrifying second, Jason thought he’d misfired, that he’d yanked them back into a space Simon wasn’t ready to revisit.

Then Simon’s head fell back against the pillow. A sound escaped him—not a laugh, but a deep, shuddering exhalation that was part shock, part surrender, part sheer, unadulterated heat. His eyes slid shut, then opened again. The look in them was completely new. It was stark hunger, stripped of all pretense, edged with a dark, delighted recognition.

“Jason,” he said, the name a ragged thing. His grip tightened, fingers biting into skin. “You can’t just… deploy a variable like that. Without warning.”

“Why not?” Jason whispered, pushing up on his arms to look down at him. His own heart was hammering. “You wrote the protocol. I’m just… requesting a continuation of the study. Participant-led inquiry.”

Simon stared up at him, his mind visibly racing, connecting this new reality to a thousand old schematics. The machine was in storage. The chair was just a chair. But the intention, the invitation—it was a key turning in a lock.

“The environment is compromised,” Simon said, his voice low and thrillingly rough. “The primary observation chamber is currently… occupied by domestic clutter. Your laundry basket is on the chair.”

Jason laughed, a bright, relieved sound. “So move it.”

Simon’s answering smile was slow, predatory, and utterly beautiful. “The subject’s enthusiasm is noted. It will be factored into the revised parameters.” He surged up, capturing Jason’s mouth in a searing, possessive kiss that tasted like promise and midnight oil and their shared, secret language. When he broke away, he was breathing hard. “Now?”

“Yeah,” Jason breathed, his blood singing. “Now.”
