Her fingers tightened in his hair—not a caress, a fistful of scalp and roots, yanking his head back so hard his neck cracked. Derek gasped, the sound wet and broken, his mouth still slick with her, the taste of her on his lips like a brand he couldn't wipe away.

"Look at him," Cassidy said, her voice a lazy drawl that slithered down his spine. She twisted his head toward the bed, toward Marcus, who was watching with that same lazy smirk, his dark eyes half-lidded and gleaming in the dim light of the bedroom. "He watched you cry and lick my cunt like a good boy. Don't you think he deserves a thank you?"

Derek's stomach lurched. A thank you. To the man who was fucking his girlfriend. To the man who sat on the bed like he owned it, like he owned everything, his broad shoulders and thick arms making the space around him feel smaller, tighter, more dangerous. Derek's throat worked, but no sound came out. His eyes were red, swollen, the tears still wet on his cheeks, and he could feel the dried tracks of them pulling at his skin.

"I—" he started, his voice cracking.

"I didn't hear that," Cassidy said, her tone dropping, colder now. She gave his hair another yank, hard enough that his eyes watered again. "Try again, Derek."

He nodded, the movement small and obedient against her pull. "Yes," he whispered. "Yes, I—I should thank him."

"Good boy." She released his hair, and he nearly collapsed forward, catching himself on his palms, the rough wool of the carpet scraping his kneecaps. The carpet was worn, thin in places, and he could feel every fiber biting into his skin as he shifted his weight. "Go on, then. Crawl."

Derek's heart hammered against his ribs. Crawl. Across the carpet, on his knees, toward the man who was watching him with that amused, predatory smile. He looked up at Marcus, and Marcus raised an eyebrow, waiting, his hand resting on his thigh like he had all the time in the world.

"You heard her, buddy," Marcus said, his voice low and rumbling, full of mock sympathy. "Don't keep her waiting."

Derek's stomach lurched again, but he moved. One knee forward, then the other, his hands dragging across the carpet as he crawled. The wool scraped his kneecaps, rough and unforgiving, and he could feel the heat of his own shame rising up his neck, flushing his cheeks. He could hear himself breathing—ragged, shallow breaths that filled the silence between the soft rustle of his knees on the carpet and the creak of the bed as Cassidy shifted her weight, settling back to watch.

Three feet. Four. The distance felt like miles, each inch of carpet a lifetime of humiliation. He could feel Marcus's eyes on him, could feel the weight of that gaze like a physical thing pressing down on his shoulders, and he kept his own eyes fixed on the floor, on the worn fibers, on the dust motes floating in the dim light.

"Look up," Marcus said, and Derek's head snapped up before he could stop himself, his body responding to the command before his mind could catch up. Marcus was leaning forward now, elbows on his knees, that lazy smirk still in place. "That's it. Let me see your face."

Derek's breath hitched. His face was a mess—tear-streaked, red-eyed, his lips still swollen from his mouth working against Cassidy's cunt. He could feel the wet slide of his own spit and her taste still on his lips, a reminder of what he'd just done, what he'd been made to do, and he could see Marcus taking it all in, cataloging every detail of his shame.

"You're really something, you know that?" Marcus said, and there was genuine amusement in his voice. "Most guys would've walked out by now. But you—" He shook his head, a low chuckle escaping his throat. "You just keep going, don't you?"

Derek didn't know how to answer that. He didn't know if it was a compliment or another knife twisting in his gut. He just knelt there, his knees burning against the carpet, his hands pressed flat against the floor, and waited.

The mattress creaked as Cassidy shifted again, and Derek heard the soft click of her phone against the nightstand. She was done filming, at least for now. He didn't know if that was better or worse—better, because the red light wasn't blinking at him anymore; worse, because it meant she was just watching now, watching him crawl, watching him beg, and he could feel her eyes on him like a physical weight.

"I think he's waiting for something," Cassidy said, her voice light, almost bored. "Aren't you, Derek?"

He swallowed hard. His throat was dry, his mouth still tasting of her, and he didn't know how to say the words she wanted to hear. But he knew she'd make him say them eventually. She always did.

"I'm—" he started, his voice cracking again. "I'm waiting for—for instructions."

"Good boy." The words were honey and vinegar, sweet and corrosive at the same time, and Derek felt his cock twitch in his sweatpants, despite everything. Despite the shame, despite the tears still wet on his cheeks, despite the fact that Marcus was watching him like he was a bug under a glass. His body didn't care about any of that. His body just wanted to please her.

He crawled the last few feet, his knees scraping against the carpet, and stopped when he reached the side of the bed. Marcus's legs were right there, his jeans stretched tight over his thighs, his boots flat on the floor. Derek kept his eyes down, his breath coming in short, shallow gasps, his heart pounding so hard he could feel it in his throat.

"Closer," Marcus said, and Derek's stomach lurched, but he moved, his knees shuffling forward until he was right at the edge of the bed, his face level with Marcus's knee. He could smell him now—leather and cologne and something else, something musky and masculine that made Derek feel small and weak and utterly out of his depth.

Marcus reached down, and Derek flinched, his whole body tensing, but Marcus's hand just gripped his jaw, fingers digging into the bone, tilting his face up. Derek's eyes met his, and he saw the amusement there, the lazy confidence, the absolute certainty that Derek was nothing, that Derek was less than nothing, that Derek was exactly where he belonged.

"That's it," Marcus said, his voice low and amused. His thumb brushed across Derek's cheek, wiping away a tear, and Derek's breath hitched at the touch, at the unexpected gentleness of it. "Show me how grateful you are."

Derek's lips parted, but the words wouldn't come. They stuck in his throat like gravel, rough and useless, while Marcus's thumb traced the wet track down his cheek again—slow, almost tender, a mockery of comfort. The gentleness was worse than the cruelty. Cruelty he knew how to brace for. This, this soft pressure against his skin, made his eyes burn with fresh tears he couldn't stop.

"I—" His voice cracked, splintered. He swallowed, tasting her still, that musky sweetness coating his tongue, and tried again. "Thank you. For—for watching. For letting me—" The words died. He didn't know how to finish them. For letting me lick my girlfriend's cunt while you watched. For letting me clean up my own mess like a dog. For not laughing louder.

Marcus's thumb stilled on his cheekbone. The smirk widened, teeth gleaming in the dim light, and Derek felt the grip on his jaw tighten just enough to hurt. "That's it? That's all you've got, buddy?" A low chuckle rumbled from his chest. "I let you put your mouth on her. I let you taste what's mine. And all I get is a 'thank you' you can barely choke out?"

Derek's stomach dropped. His hands trembled where they pressed flat against the carpet, fingers curling into the worn wool. The heat of shame crawled up his neck, flooded his cheeks, and he could feel his cock twitch again in his sweatpants—hard, traitorous, aching for something he didn't deserve. His body didn't care about the humiliation. His body wanted more.

"I'm sorry," he whispered, the words spilling out before he could stop them. "I'm sorry, I—I don't know how to say it right."

"Then show me." Marcus released his jaw, and Derek's head dropped, his chin hitting his chest. But Marcus's hand caught his hair instead, fingers tangling in the mousy strands, and yanked his face back up. "Look at me when I'm talking to you."

Derek's eyes snapped up, wide and wet, meeting Marcus's dark gaze. The amusement was still there, but something else flickered beneath it—something hungrier, more patient. Marcus's thumb found his lower lip, pressed against the swollen flesh, and Derek's breath caught.

"You know what I think?" Marcus said, voice dropping to a low rumble. "I think you like this. I think you like being on your knees, begging for scraps. I think you like knowing she chose me over you." He leaned closer, close enough that Derek could smell the whiskey on his breath, the cologne on his skin. "I think you'd do anything she told you to, wouldn't you? Anything at all."

Derek's throat worked. He wanted to deny it, wanted to say no, wanted to prove he was still a man, still someone, still anything. But the words wouldn't come. Because Marcus was right. He knew it, and worse, Cassidy knew it, and worst of all, he knew it—knew it in the way his cock throbbed against his thigh, in the way his mouth watered at the thought of pleasing them, in the way his chest ached with something that felt almost like relief.

"Yes," he breathed, the word barely a sound. "Yes, I—I would."

The mattress creaked behind him. Cassidy's voice drifted down, lazy and satisfied. "See? I told you. He just needs the right motivation."

Marcus's grin widened. His thumb pressed against Derek's lip, pushed past it, and Derek's mouth opened without thinking, tongue flat against the calloused pad. The taste of salt and skin flooded his senses, and he heard Marcus chuckle again, low and dark.

"Good boy," Marcus said, and the words hit Derek like a physical blow, sending a jolt straight to his cock. "Now show me how grateful you are. Properly."

Derek's tongue curled around the pad of Marcus's thumb, a reflex he couldn't name, couldn't stop. The salt of his skin, the faint taste of soap beneath it, and something else—something that made Derek's stomach clench even as his mouth stayed open, obedient, waiting. He heard his own breathing, wet and ragged through his nose, and he could feel the tears sliding down his cheeks again, hot and endless, dripping off his jaw onto the carpet between his knees.

Marcus held his gaze for a long moment, that lazy smirk still in place, then pulled his thumb free. It came out wet, glistening in the dim light, and Marcus wiped it on Derek's cheek like he was cleaning a knife. Derek's breath hitched at the casual intimacy of it, the way Marcus touched him like he was furniture, like he was an object to be used and set aside.

"Properly," Marcus repeated, savoring the word. He leaned back against the headboard, arms crossed over his broad chest, and nodded toward the floor between his boots. "You know what properly means, buddy? It means I don't have to ask twice. It means you open your mouth and you show me you understand what you are."

Derek's hands trembled where they pressed against the carpet. He could feel his pulse in his throat, in his temples, in the hollow behind his knees. His cock was rock hard in his sweatpants, leaking, a damp spot spreading against the gray fabric, and he hated it—hated the way his body kept betraying him, kept telling them exactly what this was doing to him.

"I understand," he whispered, the words scraping out of him.

"Do you?" Marcus's voice was almost gentle, almost kind, and that was worse than mockery. "Then tell me what you are."

Derek's throat closed. He couldn't say it. He couldn't. The words were too heavy, too true, too much like admitting that everything Cassidy had ever said about him was right. He shook his head, a tiny, desperate motion, and felt fresh tears spill over his lashes.

"Come on now," Marcus coaxed, leaning forward again. His elbows rested on his knees, his hands dangling loose between them, and he looked at Derek like he was a puzzle worth solving. "You just said you'd do anything she told you to. Anything at all. Was that a lie?"

"No," Derek breathed. "No, it wasn't—it wasn't a lie."

"Then say it."

The room went quiet. Somewhere outside, a car door slammed, and the sound felt impossibly loud, impossibly far away. Derek could hear the soft whisper of Cassidy shifting on the mattress, could feel her eyes on his back, waiting, watching. The carpet bit into his kneecaps. His mouth still tasted of her, of Marcus's thumb, of his own shame.

"I'm—" He swallowed. The word stuck in his throat like a bone. "I'm your—your good boy."

Marcus's eyebrows rose. "Our good boy?"

Derek's chest hitched. "Our—our good boy."

The silence stretched. Then Marcus laughed—a low, warm sound that made Derek's stomach flip—and reached down, gripping his jaw again, tilting his face up. His thumb traced the wet track on Derek's cheek, slow and almost tender, and Derek's eyes burned with fresh tears he couldn't stop.

"That's it," Marcus said softly. "That's what I wanted to hear."

Behind him, the mattress creaked. Cassidy's voice drifted down, lazy and satisfied, wrapping around him like silk. "See, baby? I told you he could do it. He just needs the right motivation."

Derek's eyes stayed locked on Marcus's, on the amusement gleaming there, on the certainty that he was exactly where he belonged. His cock throbbed against his thigh, aching, desperate, and he didn't know if he wanted to cry or beg or both. He just knelt there, his jaw held in Marcus's grip, his face wet, his mouth still tasting of salt and skin, and waited for the next command.

Marcus's grip on his jaw loosened, but didn't let go. Those dark eyes held him, patient, amused, like a cat watching something small twitch in the grass. Derek's pulse hammered in his throat, in his temples, in the hollow behind his knees. The words hung in the air between them— our good boy —and he could still taste them, rough and shameful on his tongue.

"You hear that, Cass?" Marcus called without looking away from Derek. "He said our good boy. Not yours. Ours."

"I heard." The mattress creaked. Derek felt her shift behind him, felt the heat of her presence as she moved closer to the edge of the bed. "Say it again, Derek. Look at me this time."

His throat closed. His eyes were still locked on Marcus's, on the gleam of amusement there, and he couldn't make himself look away, couldn't make himself turn to face her. But her hand found his hair again—not a fist this time, just fingers threading through the mousy strands, almost gentle—and she tugged, just enough to pull his head back.

"I said look at me."

He turned. Her face was above him, backlit by the dim lamp on the nightstand, her blue eyes sharp and satisfied. She was still in that tight black dress, the hem riding high on her thighs as she sat on the edge of the bed, and she looked down at him like he was something she'd scraped off her shoe and decided to keep.

"Say it," she said. "Look me in the eye and tell me what you are."

His lips parted. The words were right there, burning in his throat, and he knew—he knew —that if he said them, something in him would break for good. But her fingers were in his hair, her eyes were on his face, and his cock was so hard it ached, leaking against his thigh, and he couldn't remember how to say no.

"I'm your good boy," he whispered. "Your—our good boy."

Her smile was slow, satisfied, like a cat stretching in a patch of sun. "That's right, baby." She released his hair and leaned back on her palms, her legs parting slightly, and Derek caught a glimpse of the damp shine on her inner thighs—his work, his mouth, his shame. "You know what I think? I think you need to hear it again. I think you need to hear it while I record it."

His stomach lurched. The phone. She'd set it down on the nightstand, but now she reached for it, her fingers closing around the slim black case, and the screen lit up. The camera app was still open. The red light was still blinking.

"No—" The word slipped out before he could stop it, thin and desperate. "Please, Cass, I—"

"Please what?" She tilted her head, the phone already raised, the lens aimed at his face. "Please stop? Or please don't make you say it again?"

He didn't know. He didn't know anything except that his face was wet and his hands were trembling and his cock was so hard it hurt, and she was looking at him through the screen like he was a specimen pinned under glass.

"I think you want to say it again," she said softly. "I think you need to. Don't you, baby? Don't you need me to hear it?"

His breath hitched. The red light blinked. He could see himself reflected in the dark glass of the screen—a mess of tear-streaked cheeks and swollen lips, his hair falling into his eyes, his chest heaving.

"Yes," he breathed. "Yes, I—I need to."

"Then say it." Her voice was honey, slow and sweet. "Say it like you mean it."

His eyes stayed on the lens, on the blinking red light, on the tiny reflection of his own broken face. The words rose in his throat, heavy and inevitable, and he let them fall.

"I'm your good boy." His voice cracked on the last word, splintered like thin ice. "I'm—I'm your good boy, Cass. I'm your—our good boy. I'll do anything. I'll—I'll do anything you tell me to."

The red light blinked. The room was silent except for his ragged breathing and the faint hum of the lamp. And then Cassidy smiled—a real smile, warm and bright and utterly cruel—and lowered the phone.

"See, Marcus?" she said, her voice light, almost cheerful. "I told you. He just needs the right motivation."

Marcus chuckled from the bed. "That he does." His hand found Derek's hair again, fingers tangling in the strands, and yanked his head back. "You did good, buddy. Real good. You know what that earns you?"

Derek's heart stuttered. "What—what does it earn me?"

Marcus's grin widened. "You get to watch."

The words took a second to land. And then they hit him like a physical blow, knocking the air out of his lungs. Watch. Watch what? He didn't dare ask. He didn't dare breathe. He just knelt there, his jaw in Marcus's grip, his eyes wide and wet, and waited.

Cassidy set the phone down on the nightstand, screen-up, the red light still blinking. She didn't turn it off. She wanted this recorded. She wanted him recorded. And then she turned to Marcus, her hand finding his chest, her fingers curling into the fabric of his black polo.

"You want me to show him?" she asked, her voice dropping, going low and intimate. "Show him what he's missing?"

Marcus's eyes never left Derek's. "Yeah. I think he needs the reminder."

Derek's throat closed. His hands pressed flat against the carpet, fingers curling into the worn wool, and he watched—he couldn't look away, couldn't move, couldn't breathe—as Cassidy swung her leg over Marcus's lap, straddling him, her tight black dress riding up her thighs. Marcus's hands found her hips, gripping the fabric, pulling her closer, and she leaned in and kissed him—deep, slow, filthy, her tongue sliding into his mouth like she belonged there.

And the worst part, the part that made Derek's stomach clench and his eyes burn with fresh tears, was that she did belong there. She kissed Marcus like she'd been kissing him for years, like Derek was nothing, like Derek had never been anything at all.

He watched her hands find the hem of Marcus's polo, watched her pull it up, watched the broad expanse of his chest emerge—muscled, dark-haired, scarred in a way that spoke of a life Derek couldn't imagine. He watched her mouth trail down Marcus's jaw, down his throat, her tongue tracing a path that Derek had only ever dreamed of.

"You see, Derek?" Marcus's voice was low, rough, amused. "This is what it looks like when a woman actually wants you."

Derek's breath hitched. He couldn't answer. His tongue was glued to the roof of his mouth, his throat too tight for words, and all he could do was watch as Cassidy unbuttoned Marcus's jeans, as she pulled them down, as she freed his cock—thick and hard and heavy, darker than Derek's, heavier than Derek's, everything Derek wasn't.

"Look at it," Cassidy said, her voice drifting down to him, lazy and satisfied. She wrapped her fingers around the base, stroking slowly, deliberately, and Derek watched her hand move, watched the way Marcus's cock twitched at her touch. "Look at what a real man looks like, baby. Look at what I've been missing."

Derek's eyes burned. His cock throbbed in his sweatpants, aching, leaking, and he hated himself for it—hated the way his body responded, hated the way he couldn't look away, hated the way he wanted to watch, wanted to see her take it, wanted to see the look on her face when she did.

"Please," he whispered, not knowing what he was begging for. "Please, Cass, I—"

"Shh." She didn't even look at him. Her eyes were on Marcus's, her hand still stroking, slow and sure. "Just watch, baby. Just watch and learn."

She leaned down, her blonde hair spilling over her shoulders, and took Marcus's cock into her mouth. The sound she made—a low, satisfied hum—sent a jolt straight through Derek's gut. He watched her lips stretch around the head, watched her tongue trace the vein on the underside, watched her take him deeper, deeper, until her nose was pressed against his skin and her throat was full.

And Marcus—Marcus just leaned back against the headboard, his eyes half-lidded, his hand finding Cassidy's hair, guiding her, not forcing, just directing —and looked at Derek. Looked at him with that lazy, amused smile, like he was watching a dog salivate over a steak it would never taste.

"You see, buddy?" Marcus's voice was rough, strained with pleasure. "This is what it sounds like when a woman actually wants to please you. Not because she has to. Because she wants to."

Derek's throat worked. His hands were shaking, his knees burning against the carpet, and he could feel the wet spot spreading in his sweatpants, could feel his own arousal like a betrayal, like a wound. He was hard. He was so hard it hurt. And he was crying—hot, silent tears sliding down his cheeks, dripping off his jaw onto the carpet—and he couldn't stop any of it.

Cassidy pulled off Marcus's cock with a wet sound, her lips shiny, her eyes finding Derek's. "You like watching, don't you, baby?" She stroked Marcus's length, slow and deliberate, and Derek watched her hand move, watched the way his cock glistened with her spit. "You like seeing what I do when I'm not pretending to be satisfied with you."

Derek's breath hitched. The words cut deep, deeper than any of the others, because they were true. She had never looked at him like that. She had never touched him like that. She had never wanted him like that, and he'd known it, had felt it in the way she'd always pulled away, the way she'd always made him work for scraps, the way she'd always made him feel like he was performing for her approval instead of earning her desire.

"I'm sorry," he whispered, the words spilling out of him like water from a cracked vessel. "I'm sorry, Cass, I—I know I'm not—I know I can't—"

"Can't what, baby?" Her voice was soft, almost kind, and that was worse. "Can't make me feel the way he does? Can't make me want you the way I want him?"

He shook his head, a tiny, desperate motion. "I—I don't know. I don't know how."

"I know." She turned back to Marcus, her hand still stroking him, her mouth finding his again. "That's why you watch. That's why you learn. That's why you're on your knees, Derek. Because you don't know how, and I'm tired of teaching you."

Her mouth moved on Marcus's, slow and deliberate, and Derek watched her hand work his cock in the same rhythm—stroke, twist, stroke—like she couldn't help syncing the two. The wet sound of her lips parting from Marcus's filled the room, and she looked down at Derek with that lazy, half-lidded gaze that made his stomach drop through the floor.

"You want to come?" she asked him, her voice a low murmur. "You want to come in your pants like a teenager, watching me suck his cock?"

Derek's breath caught. The question was a trap no matter how he answered it, and they both knew it. His cock throbbed against his thigh, a desperate, aching pulse that had nothing to do with his will and everything to do with the wreckage she'd made of him.

"Please," he heard himself say, the word sliding out of him without permission. "Please, Cass, I—I can't—"

"Can't what?" She tilted her head, her fingers still wrapped around Marcus's shaft, stroking him with a lazy, practiced rhythm. "Can't hold it? Can't stop yourself from coming while you watch me with a real man?"

Marcus chuckled, low and dark. "Give him a break, Cass. He's been a good boy. Let him have his little reward."

Derek's eyes darted to Marcus, hope flaring in his chest—a thin, desperate flame. But the smile on Marcus's face was not kind. It was the smile of a man who had already decided how this would go, and was simply enjoying the anticipation.

"Please," Derek whispered again, his hands pressing flat against the carpet, his knees aching from the hard floor. "Please, I'll do anything. I'll—I'll be good. I'll be so good."

"I know you will, baby." Cassidy's voice was honey, slow and sweet and poisonous. She released Marcus's cock and shifted on the bed, turning to face Derek fully. Her dress had ridden up, exposing the tops of her thighs, and he could see the damp shine on her skin—his work, his mouth, his shame. "That's why I'm going to let you watch. That's why I'm going to let you see exactly what you're missing."

She reached for the hem of her dress and pulled it over her head in one smooth motion, and Derek's breath left his body in a rush. She wasn't wearing a bra. She wasn't wearing anything at all, and the sight of her—pale skin, pink nipples, the flat curve of her stomach—sent a jolt of pure, animal want straight through his gut.

"You like that, baby?" She ran her hands up her own sides, slow and deliberate, letting him look. "You like seeing what you can't have?"

His mouth opened, but no sound came out. He could only kneel there, his eyes fixed on her body, his cock straining against his sweatpants, and nod.

"Good." She turned back to Marcus, positioning herself over his lap, her knees on either side of his hips. "You watch, Derek. You watch and you learn."

Marcus's hands found her hips, gripping her, pulling her closer. His cock stood thick and hard between them, dark and heavy, and Derek watched as she reached down and guided it to her entrance. He watched her lower herself onto it—slow, inch by inch, her lips parting around a soft moan—and he felt something inside him crack, a fissure spreading through his chest.

"Fuck," Marcus breathed, his head falling back against the headboard. "God, Cass. You feel incredible."

"Mmm." She rocked her hips, taking him deeper, her eyes fluttering closed. "You feel good too. So thick. So—" She opened her eyes, finding Derek's face, and her smile was a knife. "—so much more than I'm used to."

Derek's throat closed. The words were a blow, precise and brutal, and he felt them land in his gut like a stone dropped into still water. He was used to being compared to other men in her mouth—she'd made that a habit over the years, a casual cruelty that she wielded like a scalpel—but hearing it now, with her stretched around Marcus's cock, was a different kind of wound.

She began to move, a slow, rolling rhythm that made her hips sway and her breasts bounce gently with each motion. Marcus's hands gripped her hips, guiding her, and his eyes found Derek's over her shoulder—dark, amused, triumphant.

"You see, buddy?" Marcus's voice was rough, strained with pleasure. "This is what it looks like. This is what it feels like when a woman actually wants you."

Derek couldn't answer. He could only watch, his hands fisted in the carpet, his knees burning, his cock aching and leaking in his sweatpants. He could see everything—the way Cassidy's body moved, the way Marcus's hands held her, the way their bodies joined in a rhythm that looked practiced, familiar, like they'd done this a hundred times before.

And he could see the phone on the nightstand, screen-up, the red light still blinking. She was recording this. She was recording him watching, and the thought made his stomach clench with a shame that was somehow also arousal, a sick, twisted thrill that he couldn't untangle.

"Look at him," Cassidy murmured, her voice drifting down to him, lazy and satisfied. "Look at him watching us. You see his face, Marcus? You see how pathetic he looks?"

"I see it." Marcus's hand found her hair, pulling it back from her face, baring her throat to his mouth. "He's learning, aren't you, buddy? Learning what you'll never be able to give her."

Derek's breath hitched. The words were true, and they cut deeper than any blade, because he knew—he'd always known—that he couldn't give her what Marcus could. He was too small, too quick, too eager to please, and she'd always made him feel it, in a thousand small ways that had worn grooves into his soul.

The words landed like a verdict, heavy and final. Derek's hands pressed flat against the carpet, his fingers curling into the worn wool, and he watched—he couldn't look away, couldn't move, couldn't breathe—as Cassidy began to ride Marcus in earnest, her hips finding a rhythm that made the bed creak and her breath come in soft, broken gasps.

"Oh—fuck—" She threw her head back, her blonde hair spilling down her spine, and Marcus's hands gripped her hips, slamming her down onto his cock with a force that made Derek flinch. "Yes—right there—don't stop—"

Marcus's eyes never left Derek's. Dark and triumphant, they held him pinned as he drove up into Cassidy, each thrust a punctuation mark in a sentence Derek couldn't read. "You like this, buddy? You like watching her come on my cock?"

Derek's throat worked. He couldn't answer, couldn't speak, couldn't do anything but kneel there and feel his own body betray him—his cock straining, aching, leaking against his thigh, his heart hammering, his eyes burning with tears he couldn't stop.

"Answer him," Cassidy said, her voice strained, her rhythm faltering. "Answer him, Derek. Tell him you like it."

"I—" His voice cracked. "I like it. I like watching. I like—" The words stuck in his throat, but he forced them out, because she'd asked, because she'd told him to, because he couldn't say no to her, not anymore. "I like watching you, Cass. I like—I like seeing you happy."

Cassidy laughed—a bright, cruel sound that made his stomach clench. "You hear that, Marcus? He likes seeing me happy. He likes watching me get fucked by a real man."

"He's a good boy," Marcus said, his voice a low rumble. "Aren't you, buddy? A good boy who knows his place."

Derek nodded, a jerky, desperate motion. "Yes. Yes, I'm—I'm a good boy. I know my place. I know—" He swallowed, the words burning like acid. "I know I'm not—I know I can't—"

"You can't what?" Marcus's voice was patient, almost kind, and that was worse. "You can't make her feel the way I do? You can't satisfy her the way I can?"

Derek's eyes burned. He looked at Cassidy—at the flush on her cheeks, the shine in her eyes, the way her body moved on Marcus's cock with a pleasure he'd never been able to give her—and he knew. He knew it was true. He'd always known it, in the way she'd always pulled away, the way she'd always made him work for scraps, the way she'd always made him feel like he was performing for her approval instead of earning her desire.

"Yes," he whispered, the word tasting like ash. "Yes, I know. I know I can't."

"Good boy," Marcus said, and the praise was a knife, twisting in his gut. "Now watch. Watch her come on my cock. Watch her remember what it's like to be satisfied."

Derek watched. He couldn't do anything else. He watched Cassidy's body tighten, watched her head fall back, watched her mouth open around a cry that wasn't his name, watched her come undone on Marcus's cock while he knelt there, hard and leaking and utterly, completely forgotten.

"Oh—fuck—Marcus—" Her voice was broken, desperate, and Derek felt the sound of it like a physical blow, knocking the air from his lungs. "Don't stop—please—don't stop—"

Marcus didn't stop. He drove into her, harder, faster, his hands gripping her hips with a force that would leave bruises, and Derek watched the way her body shook, the way her thighs trembled, the way she came apart in his arms—and he knew, with a certainty that hollowed him out, that she had never looked like that with him. She had never cried his name like that. She had never come apart in his arms the way she was coming apart in Marcus's.

"You see, buddy?" Marcus's voice was rough, strained with his own approaching release. "This is what it looks like. This is what it feels like when a man knows how to fuck her. When a man knows what she needs."

Derek nodded, a tiny, broken motion. "Yes," he whispered, the word barely audible. "Yes, I see. I—I see."

"Good." Marcus's hand found the back of Cassidy's neck, pulling her down for a rough, possessive kiss. "Now watch me come in her. Watch me fill her up the way you never could."

Derek's throat closed. His eyes burned, his chest ached, and his cock—his treacherous, betraying cock—throbbed with a desperate, aching need that he couldn't deny. He watched Marcus's body tense, watched his jaw clench, watched the way his hands gripped Cassidy's hips as he came inside her, and he felt the wet heat of his own release spread through his sweatpants, a shameful, pathetic echo of the act he was witnessing.

He came without being touched. He came watching another man fuck his girlfriend, and the shame of it—the pure, distilled shame—was somehow the most arousing thing he'd ever felt.

Cassidy collapsed against Marcus's chest, her breath coming in soft, satisfied gasps, and Marcus wrapped an arm around her, holding her close. His eyes found Derek's over her shoulder, and his smile was slow and satisfied.

"You came, didn't you, buddy?" Marcus's voice was low, amused. "You came in your pants watching me fuck her."

Derek's face burned. He couldn't deny it, couldn't hide the wet stain spreading through his sweatpants, couldn't do anything but kneel there, broken and exposed, and nod.

"Look at that," Cassidy murmured, her voice lazy and satisfied. She lifted her head from Marcus's chest, her eyes finding Derek's, and her smile was a knife. "Look at him, Marcus. He came in his pants like a teenager. Like a pathetic little boy who can't control himself."

"He's learning," Marcus said, his hand stroking Cassidy's hair. "He's learning his place."

Cassidy slid off Marcus's lap, her thighs slick with his release, and knelt on the bed in front of Derek. She reached down and hooked her fingers into the waistband of his sweatpants, pulling them down just enough to free his spent, softening cock—still wet with his own shame.

"Look at that," she said softly, her fingers wrapping around him, stroking the slick head. "You came so fast. You didn't even get to touch yourself. You just watched me with a real man, and you came."

Derek's breath hitched. Her touch was electric, even now, even after everything—his cock twitched in her hand, a pathetic, desperate response that made her smile.

"Shh." She released him, her hand moving to cup his face, tilting his head up to meet her eyes. "You did good, baby. You watched. You learned. You came when I told you to." Her thumb traced the line of his jaw, and her voice dropped, low and intimate. "That's what I need from you. That's what you're good for."

Derek's eyes burned. The words were a wound and a balm at once—cruel and kind, cutting and healing, and he couldn't tell which was worse. He leaned into her touch, his eyes closing, his breath shuddering out of him, and he felt her hand move to the back of his head, pulling him forward.

"Come here," she murmured. "Clean me up. Show me what a good boy you are."

His eyes opened. She was spread before him, her thighs still slick with Marcus's release, and he understood—with a clarity that hollowed him out—what she was asking. He leaned forward, his hands pressing flat against her thighs, and lowered his mouth to her skin.

He tasted Marcus on her. He tasted the proof of his own inadequacy, and he lapped at it like a man dying of thirst, his tongue working between her folds, cleaning her with a desperate, pathetic devotion that made his eyes burn with fresh tears.

"That's it," she murmured, her fingers threading through his hair. "That's my good boy. That's exactly what I need from you."

Derek sobbed against her skin, a broken, desperate sound, and kept licking. He kept cleaning. He kept being her good boy, because it was the only thing he was good for, the only thing she'd ever let him be.

And when she finally pulled him away, her hand gentle on his jaw, her eyes soft and cruel, he looked up at her with a face wet with tears and a heart that had shattered into a thousand pieces—and he smiled.

"I'm your good boy," he whispered, the words a confession and a surrender. "I'm your—our good boy. I'll do anything. I'll—I'll do anything you tell me to."

Cassidy smiled, warm and bright and utterly cruel, and leaned down to press a kiss to his forehead—a benediction, a reward, a curse.

"I know, baby," she murmured against his skin. "I know."
