The next morning, the dull gray light of a low, heavy sky seeped through the thin curtains of Madison’s apartment, casting soft shadows over the stacks of open economics textbooks scattered across her coffee table. She sat cross-legged on the worn couch, a highlighter in hand, a mug of cold coffee abandoned at her feet, making a half-hearted attempt to focus on a chapter about financial markets. The words swam before her eyes, blurring into meaningless sludge, and she reread the same sentence for the fifth time without absorbing a damn thing.
Fuck, focus, Madi, she scolded herself, but it was useless. Her thoughts kept drifting back to the day before—to that bench in the mall, Rebecah’s sly laugh, and the proposition that had knocked everything off its axis.
She’d slept like shit—broken, restless sleep, littered with confused dreams where unpaid bills tangled with hazy flashes of bare skin and knowing looks. Rebecah had flat-out refused their request for an advance, claiming with a calculated smile that “it would make things less exciting,” but she’d promised to pay them every cent right after ... the job. Twenty-one thousand dollars. Jesus. Enough to fix everything, yet now it sat on her chest like a concrete block. With a frustrated grunt, Madison tossed her highlighter onto the table and jumped to her feet, pacing the cramped room.
“Seriously, what the hell is wrong with me? It’s just exam prep, not the end of the world,” she muttered, her hands shaking as she dragged them through her tangled hair. But she knew exactly what was eating at her—the waiting, that deal hanging over her head like a blade, and the fact that Rebecah was the one holding all the strings.
Irritated, she grabbed her phone from the kitchenette counter and fired off a message to Alan without thinking: “Still nothing from that crazy bitch? Not knowing is seriously freaking me out.” She hit send and stared at the screen as if an answer might magically appear. Nothing. With a sigh, she tossed the phone onto the couch and forced herself back to her notes, willing her brain to cooperate. The minutes stretched on. When her phone finally buzzed half an hour later, she lunged for it.
Just a blunt “no” from Alan. No punctuation, no emoji—nothing. A surge of irritation burned through her, her lips pressing into a thin line. “Awesome, thanks for the detailed update,” she muttered, flinging the phone aside again. She was sick of pacing in this shitty apartment, its walls seeming to close in on her. She needed air. Space. She threw on a light coat over her hoodie, grabbed her keys, and slammed the door behind her, heading down the creaking stairs to lose herself in the campus streets—anything to clear her head before the pressure finally crushed her. ---
Alan was stepping out of the campus gym, his muscles still warm and aching after an intense lifting session, his T-shirt plastered to his damp skin under the cool afternoon breeze. The low concrete building—its walls tagged with graffiti, its windows fogged up from condensation—still hummed with the clatter of weights and the thump of motivational playlists bleeding through the walls. He hitched his gym bag higher on his shoulder, nodding to a few regulars heading out at the same time, when Sean caught up to him, a towel slung around his neck and a tired grin on his face.
“Hey man, solid workout! You really went all in today,” Sean said, giving him a friendly slap on the back while wiping sweat from his forehead.
Alan chuckled, still a bit out of breath.
“Yeah, thanks to your expert advice. Without you, I’d have bailed after the third set. See you—don’t let me miss the materials lab tomorrow, or I’m screwed.”
Sean nodded, thumb up. “For sure. Catch you there. Get some rest—you look like a zombie.”
They split with a quick fist bump, Sean heading toward the west dorms while Alan took the opposite direction, back toward his crappy apartment on the edge of campus. The streets were lively at this hour: students on bikes weaving through pedestrians, the smell of fresh coffee drifting from a food truck parked on the corner, the low sun throwing golden light over the yellowing leaves.
Alan walked at a steady pace, trying to shake the mental fog that had followed him all day—that shopping trip that had gone to hell, Madison and her stupid proposition looping in his head like a bad chorus he couldn’t shut off.
His phone buzzed in the pocket of his gym shorts, a short vibration that made him sigh.
Madi again? Seriously, she’s getting on my nerves—she already blew up my phone this morning, he thought as he pulled it out, ready to ignore yet another stressed-out message. But the name on the screen stopped him cold.
Rebecah.
His heart kicked harder as he opened the message, short and to the point:
“This evening. Hôtel Le Rivage, 8 p.m. Don’t be late... ❤️😘😉”
It wasn’t a threat—no. More like raw, barely contained excitement, almost feverish, bleeding through the emojis and ellipses, like she was already buzzing with anticipation. Fuck. A wave of dizziness hit him, his legs going weak, and he dropped heavily onto a nearby bench, the cold wood biting into his thighs through the thin fabric. Tonight? Fuck, already? He reread the message three times, trying to process it, his pulse hammering in his temples like he’d just sprinted flat out.
Hôtel Le Rivage—a classy place downtown, not his kind of scene at all, with sleek façades and rooms that probably cost a small fortune. It made everything feel too real, too close. He swallowed hard, pulled out his phone, and called Madison without thinking, fingers trembling on the screen.
She picked up on the second ring, her voice stretched tight as a wire about to snap.
“—Alan? Any news?”
“Yeah ... She just texted. It’s for tonight, Madi. Hôtel Le Rivage. Eight o’clock. With hearts and smileys, like it’s some normal fucking date.”
There was a stunned silence, then Madison exploded, her voice shooting up an octave.
“What? Tonight?! That’s way too soon, fuck, way too sudden! Is she messing with us or what? We didn’t even have time to— to get ready, or think this through! Fuck, Alan, what do we do?”
They talked over each other in a rush—her spiraling over the timing, him trying to calm her down while feeling his own stomach knot tighter by the second.
“We don’t go, Madi ... I—I don’t want to, seriously. We can say no, ask to push it back, or just—”
She cut him off sharply, her voice cracking like a whip through the line.
“Fuck, Alan, we can’t! What if she cancels everything? She already refused the advance, and I need that money, fuck. We don’t take risks. We go tonight. It’s just ... two hours, like we said.”
A heavy, resigned sigh followed, and Alan finally caved.
“Okay ... okay, fuck. Tonight, then.”
He sent a simple “OK” to Rebecah, heart pounding, before going back to Madison, trying to sound normal—almost. ---
Then he felt another vibration against his palm—a persistent buzz that made him flinch on the bench.
“Wait—another message,” he muttered, glancing at the screen. It was Rebecah again. This time, a link, with a short text: “Sign this before you come. Kisses.”
He let out a nervous laugh, forced, brittle, sounding fake even to his own ears.
“What the fuck? Seriously—she’s sending us a contract to sign digitally now? What is this shit?”
Madison exhaled on the other end of the line, tension and irritation bleeding into her voice. “I just got it too. Same thing—SMS, link to an online doc. Fuck ... she really planned everything, didn’t she?”
They clicked at the same time. The document opened on both their screens—a formal PDF, neat blocks of text in an austere font, numbered clauses, and a box at the bottom for an electronic signature. Alan started reading out loud, hesitating, while Madison filled in the gaps, like they were dissecting some absurd instruction manual together.
It was a confidentiality agreement, plain and simple, with a promised payment of twenty-one thousand dollars once everything was completed, paid immediately by bank transfer. They went quiet for a second, the number flashing in their heads—twenty-one grand, fuck, burned in there like it was written in fire.
The first clauses were almost boring, almost reassuring in their dryness: absolute prohibition on filming or recording anything, under threat of legal action; total discretion about the event, including toward any third party; no illegal substances on site; and a clause stating that consent had to be mutual at every step.
Further down, though, it got real. Concrete. Visceral.
The contract specified that Alan and Madison could choose not to touch each other, but that they were required to comply with Rebecah’s requests—within the limits of explicitly given consent—for any sexual act involving either of them with her. It was all wrapped in dense legal jargon, endless paragraphs about liability and waivers, spelling out that everything was consensual, voluntary, and designed to protect against any later regret or dispute.
A full release. Like signing up for a skydiving jump—except for something way more fucked up.
