The failing attempts of Kyle lasting longer than a few seconds was doing numbers on his self-confidence. Sure, he was devoted to his marriage and to his much younger, stunningly gorgeous wife, Heather, but the toll of his inability to satisfy her was beginning to show.

It had been six long months since Heather, prompted by advice from her sister, decided to take matters into her own hands, quite literally. Kyle's struggles with premature ejaculation had led them down a path of exploration, one that involved him being locked into a chastity device.

The first month, full of anticipation and eagerness to please, he lasted a measly two minutes before cumming all over her delicate hands. Embarrassed, he apologized profusely, but Heather, always the understanding wife, reassured him that it was okay and they would try again next month.

And try they did. Each month, with increasing frustration, Kyle's performance deteriorated. Fifteen seconds, ten seconds, it seemed like he was getting further and further away from their goal of five minutes.

After each failed attempt, Heather would gently remind him of the consequences if he didn't improve. The terms were clear: if he couldn't last five minutes after six months of chastity, he would remain locked in chastity for an additional six months, and their relationship would take on a new dynamic—cuckoldry. She would be free to take on other lovers, satisfying her desires however she pleased, while he remained faithful and obedient.

The pressure was immense, and Kyle could feel the weight of it bearing down on him. His devotion to Heather and their marriage was unquestionable, but his body seemed to have a mind of its own, betraying him at every turn.

Now, as they approached the six-month mark, the stakes had never been higher. Heather, ever the elegant and commanding presence, had made it clear that this was his final chance. If he couldn't last, the consequences would be enacted, and a new chapter in their relationship would begin.

Kyle's heart raced as he considered the prospect. A part of him, the submissive, yearned for the surrender of control, the thrill of watching his wife with another. But the devoted husband wanted desperately to be the one to satisfy her, to be enough for her.

Heather entered the bedroom, her presence filling the space with an aura of sensual dominance. She was a vision in dark purple lingerie, the color a striking contrast to her fair skin. The delicate fabric hugged her curves, teasingly revealing her soft, large breasts and the swell of her hips. Stockings ran up her long, toned legs, accentuating their length and emphasizing the perfect roundness of her ass. Her bearing was regal, her movements deliberate and full of purpose.

Kyle's breath caught in his throat as he took in the sight of his wife. His heart raced, and he could feel his cock twitch, already leaking in his chastity cage. The months of denial had heightened his sensitivity, and the mere presence of Heather was often enough to push him toward the edge.

"My, my, someone is certainly eager," Heather purred, a mischievous glint in her eye. She saided over to the bed, her hips swaying seductively, and ran a hand gently along Kyle's cheek. "Are you ready for our little test, my dear?"

Kyle nodded, unable to form words, his mouth suddenly dry. He felt a mix of anticipation and nervousness as he considered the consequences of failure.

Heather smiled, her red lips curving wickedly. "You know what's at stake, don't you, my sweet Subby?" She traced a finger down his chest, her nails gently scratching the skin. "If you can't last, I'll be free to take on other lovers. Strong, virile men who can satisfy me in ways you can't."

Kyle swallowed hard, his eyes fixed on Heather's face. "Y-yes, babe," he managed to croak out.

"I'll fuck them senseless," she continued, her voice low and seductive. "Big, muscular men with thick cocks that can give me what I crave. And you'll be locked away, helpless to do anything but watch and service me when I deem it fit."

Kyle bit his lip, his cock throbbing relentlessly. The image of Heather with another man, of being denied her touch and pleasure, sent waves of desire and dread coursing through him.

"I'll have them fuck me in every position," she went on, her breath warm against his ear. "Fill me up with their thick cocks while you watch, desperate and locked away. They'll make me scream with pleasure, and I'll relish every moment."

Heather's fingers trailed down to the chastity device, and she gave it a gentle squeeze, causing Kyle to gasp and buck his hips involuntarily. "You know what will happen if you don't last, don't you, slut?"

Kyle held back tears, his eyes fixed on Heather as he nodded mutely. The weight of the moment pressed down on him, and he felt a mix of emotions: dread, desire, and a profound devotion to this woman who held his heart and his sexual fate in her hands.

Heather's fingers lingered on the chastity device for a moment longer, as if savoring the control she had over her husband's pleasure. Then, with a deliberate movement, she reached for the key that hung around her neck. She teased him as she always did by dangling it in front of his face; she slowly inserted it into the lock. With a soft click, she released Kyle from his months-long confinement.

Instantly, Kyle's cock sprang to attention, throbbing with pent-up desire. It twitched and jumped, a pitifully small member that seemed to have shrunk during its captivity. Heather sighed, a mix of amusement and disappointment playing on her features. "Look at that tiny thing," she cooed, reaching out to stroke it gently. "Chastity certainly hasn't made it any bigger, has it, slut?"

Kyle whimpered, his face flushing with embarrassment. He wanted to hide from the truth of her words, from the reality of his inadequacy. "Y-you know I love you, babe," he stammered, his voice trembling. "I'll do anything to please you."

Heather's eyes sparkled with a mischievous light as she continued her verbal assault. "Anything, hmm?" She traced a finger along his shaft, her touch light and teasing. "Because if you can't last, you won't be seeing me like this again. All the sexy lingerie and costumes we bought together... they'll be for the other men I'll be fucking." She let out a soft, evil little laugh, "Men who can fill my pussy properly."

Kyle's eyes widened as the implication sank in. He loved seeing Heather dressed up, the way she exuded power and sexuality in those outfits. The thought of never experiencing that again, of her wearing those outfits for other men, sent a stab of longing and desperation through him.

"And the blowjobs," she continued, her voice dropping to a sultry whisper. "You won't be feeling my lips wrapped around your cock again. Not ever." She leaned in close, her breath tickling his ear. "But I'll be sucking and deepthroating the biggest, thickest cocks I can find. Taking them down my throat, tasting their precum, and swallowing every last drop of their cum."

Heather's words hit Kyle like a punch to the gut. The image of her taking other men down her throat, swallowing their cum, was almost too much to bear. His cock twitched painfully, a mix of arousal and anxiety coursing through him.

With a knowing smile, Heather walked over to the dresser, her hips swaying seductively with each step. She opened the top drawer and pulled out a massive dildo, easily ten inches in length. She strolled back over to the bed, a playful gleam in her eye, and held it up for Kyle to see. "This," she said, her voice steady and assertive, "is the size of the cocks I'll be sucking if you can't last, Subby."

Kyle's eyes widened as he took in the size of the dildo. It was thick and veiny, with a lifelike head that glistened slightly in the soft light of the bedroom. He felt a wave of inadequacy wash over him as he compared it to his own small member.

"Hold it up for me, slut," Heather commanded, her voice laced with authority. "Let's see just how small you are in comparison."

Kyle did as he was told, his hand trembling slightly as he held the base of the dildo, pointing it toward Heather. The size difference was stark, and it only served to emphasize his shortcomings.

"Now, watch," she instructed, her eyes fixed on his. "Watch as I show you what I'll be doing with those big, thick cocks if you fail me."

Kyle's breath quickened as Heather lowered herself to her knees in front of him. She reached out and took the dildo from his hand, holding it steady as she leaned forward and swirled her tongue around the head. Her soft, pink tongue flicked and teased, sending little shocks of electricity through Kyle's body. She closed her eyes and moaned softly, the vibrations traveling down the length of the dildo.

Heather's full red lips parted, and she took the head into her mouth, sucking gently as she swirled her tongue around it. Her hand began to move in tandem with her mouth, stroking the shaft slowly and sensually. She bobbed her head, taking more of the dildo into her warm, wet mouth with each motion. Her lips stretched around it, her saliva providing lubrication as she slid her mouth up and down, her hand moving in perfect synchronization.

The sound of her sucking filled the room, a wet, sloppy symphony that sent Kyle's mind reeling. He watched, mesmerized, as his wife deepthroated the dildo, her throat muscles contracting as she took it all the way down. She held it there for a moment, her nose pressing against the base, before slowly pulling back, her tongue flicking and dancing along the length as she did so.

Heather looked up at Kyle through her long lashes, her eyes sparkling with a mixture of lust and power. "Do you like watching me suck a big cock, slut?" she asked, her voice husky and filled with desire. "Does it make your tiny little cock hard knowing that I could be doing this for someone else?"

Kyle could only nod, unable to form words as he stood there, transfixed by the sight of his wife's sensual blowjob. The head of the dildo glistened with her saliva, and she swirled it around, making sure to coat it thoroughly before resuming her rhythmic bobs. Her hand moved faster now, stroking the dildo in time with her mouth, her soft, wet sounds filling the air.

Heather pulled the dildo from her mouth with a popping sound, a strand of saliva connecting her lips to the tip. She took a moment to stroke it slowly, her eyes locking with Kyle's as she tormented him with her words. "You know, by now, your little cock would've splattered its tiny load all over," she purred, running her tongue over her lips. "Three times over, actually."

Kyle's eyes flickered with a mix of emotions as he stood there, his small member throbbing in time with his heartbeat. He was hooked on her every word, his breath quickening as she continued.

"God, it feels so good in my mouth," she moaned, wrapping her full lips around the dildo's head for a moment before pulling back. "So thick and veiny. It's been so long since I've felt a real cock, and this... this is making me so wet." She gave a little laugh, cruel and playful at the same time. "Maybe I'll suck you off one last time before I lock you up again, just so you can experience the difference. Feel how much tighter my mouth is around a real cock."

Heather's fingers trailed down to her pussy, and she slipped two digits inside, moaning softly as she gently fucked herself. "God, I miss it," she whispered, her eyes fluttering closed for a moment as she savored the sensation. "I miss being a slut, fucking and sucking whenever I wanted. My exes... they all had such big cocks. So much bigger than yours, Subby."

Kyle's gaze dropped to the floor, unable to meet her eyes as he felt the weight of her words. His shoulders slumped, and he let out a quiet sigh, his cock twitching pathetically in response to her verbal assault.

"I can't wait to be that slut again," Heather continued, her voice taking on a dreamy quality as she stroked the dildo. "To feel a thick, hard cock stretching me, pounding me, and making me scream. To have my mouth filled with hot cum while my pussy gets ravaged." She paused, opening her eyes and fixing Kyle with an intense stare. "And you'll be locked away, denied any pleasure, knowing that I'm out there, taking cock after cock, cucking you."

The sadness and jealousy were palpable in the room, hanging heavy in the air like a thick fog. Kyle's heart ached as he processed the image of his beautiful wife being taken by other men, of her moans and screams of pleasure belonging to them. He felt deflated, his small cock seeming to shrink further, as if it wanted to hide from the comparison.

"Enough teasing, slut. It's time for your final chance to save yourself from a life of chastity and cuckolding." Heather's voice was firm, laced with a mix of excitement and anticipation. She placed the dildo back on the bed, a knowing smile playing on her lips as she set the timer for five minutes on her phone.

Kyle's breath hitched as he processed her words. This was it—the moment he had both dreaded and longed for. His cock twitched uncontrollably, a bead of pre-cum forming at the tip, which Heather noticed immediately.

"Look at you, already leaking," she teased, her eyes fixed on his straining member. "So desperate and pathetic. There's no way you're lasting one minute, let alone five." She shook her head, a mock expression of disappointment on her face as she knelt in front of him.

Kyle sat on the edge of the bed, his heart pounding in his chest. The weight of the moment bore down on him, and he felt a mix of excitement and fear as he realized this could be the last time he experienced the touch of his wife.

"Please, babe..." The words escaped his mouth before he could stop them. It was a plea, a desperate attempt to stall the inevitable. "Don't tease me too much. I might not stand a chance."

Heather's eyes sparkled with amusement at his words. "Oh, my sweet Subby," she cooed, reaching out to stroke his thigh. "I'm not teasing you. I'm just speaking the truth. Look at that tiny cock, it's already ready to blow. How sad."

Kyle bit his lip, feeling a mix of embarrassment and arousal as he watched Heather's every move. He could feel the precum continuing to leak from the tip of his cock, a Pavlovian response to his wife's beauty and dominant nature.

"Are you ready to begin, my dear?" Heather asked, her voice dripping with honeyed seduction. "Or do you need more time to prepare yourself for the inevitable?" She tilted her head, her long hair cascading over her shoulder, as she regarded him with a mixture of lust and anticipation.

Kyle swallowed hard, knowing that there was no delaying the inevitable. He took a deep breath, steeling himself for the challenge ahead. "I'm ready, babe," he said, his voice steady despite the turmoil of emotions raging within him.

Heather's lips curved into a wicked smile. With a gentle touch, she wrapped her fingers around his cock, already slick with precum. "Let's see how long you can last, slut," she whispered, her thumb rubbing the sensitive tip. "The timer starts now."

Heather's delicate fingers wrapped around Kyle's throbbing cock, and she began to stroke him slowly and lightly. The sensation was electric, each touch sending a jolt of pleasure through him. But it was too much, too soon. Kyle's body was hypersensitive, conditioned by months of denial. As the timer hit four seconds, he began to whimper, his hips bucking involuntarily.

"Oh, come on, slut!" Heather teased, her voice a mix of mock pleading and cruel amusement. "Hold back! Don't you dare cum yet! Last for me, or I swear, I'll be on my knees sucking those big, thick cocks." As she spoke, her grip tightened and her strokes became firmer and faster. She pumped his cock with deliberate force, her thumb rubbing across the sensitive head with each upward motion.

Kyle's breath hitched, his eyes widening as he tried to hold on, to fight against the overwhelming urge to climax. Heather's pleas were tormenting, filling his mind with vivid images of her on her knees, taking those massive cocks down her throat. At eight seconds, he cried out, his body convulsing as he shot a massive load all over Heather's hand and wrist.

Heather laughed, a wicked sound that filled the room as she continued to stroke him through his orgasm. "That's it, slut! Cum for me!" She squeezed his sensitive cock, milking him for every drop as his hips bucked and his breath came in sharp gasps. "What a pathetic little mess you are," she cooed, her fingers slick with his release. "You can't even last ten seconds, can you?"

Kyle slumped forward, his chest heaving as he tried to catch his breath. His cock twitched helplessly in Heather's firm grip, still pulsing with aftershocks of his release. He was spent, his body wrecked, and his mind swirling with a mix of emotions: shame, arousal, and a profound devotion to the woman who held his pleasure and his heart in her hands.

"Look at this mess you made," Heather continued, her tone cruel and authoritative. "You couldn't even control yourself for ten seconds. Pathetic." She rubbed her wrist, still coated with his cum, across his sensitive cockhead, smearing the sticky fluid across his skin. ."

Kyle whimpered, his eyes closing as he processed the cruel reality of the situation. He knew he had failed, that he would face the consequences of his lack of control.

The post-orgasm haze clouded Kyle's mind, a mix of emotions washing over him as he processed what had just transpired. Sadness and jealousy consumed him, the realization of his failure and the impending consequences weighing heavily on his heart. He knew he had let his wife down, and the thought of her with another man sent a stab of pain through his chest.

Heather, ever mindful of her husband's shifting mental state, seized this moment of post-orgasm clarity to be deliberately cruel. She knew that with his horniness subsided, he would be thinking more rationally, and the sting of her words would bite deeper.

"Look at you, a pathetic mess," she taunted, her eyes flashing with a mixture of anger and disappointment. "You couldn't even hold out for ten seconds. My poor little cucky, so quick to spill his worthless load." She shook her head, her lips twisted in a cruel smirk. "You know, I almost feel sorry for you. Almost."

Kyle bit his lip, his eyes downcast as he endured her verbal assault. He could feel the warmth of embarrassment creeping up his neck, his face burning with shame. He knew he deserved her scorn, but it didn't make it any easier to bear.

"Your cock," she continued, her voice dripping with contempt, "is so tiny and pathetic. It's a wonder you can even call yourself a man. I bet real men, with their big, thick cocks, would laugh at the sight of this little thing." She reached out and poked his now-flaccid penis, her finger prodding it dismissively.

Kyle winced, both from the physical touch and the harsh words. He had always been self-conscious about his size, and Heather's relentless ridicule only served to highlight his insecurity. He remained silent, knowing any response would only fuel her cruelty further.

"And let's not forget how quick you are to cum," she went on, clearly relishing every moment of his anguish. "One touch, one little stroke, and you're done. It's laughable, really. How did I ever think you could satisfy me?" She laughed, a harsh sound that echoed in the bedroom. "I might as well be celibate if I have to rely on this pathetic thing."

As if that wasn't enough, Heather twisted the knife even further. "You know, I already have a guy on standby for tonight," she purred, her eyes sparkling with sadistic glee. "He's waiting for my call, ready to give me the pounding I deserve. A real man, with a real cock." She paused, letting her words sink in, before adding, "Maybe I'll just let him fuck me raw, fill my pussy with his cum while you watch, helpless and trapped in your little cage."

The image of another man taking his wife, her moans of pleasure echoing through the room, was like a knife twisting in Kyle's gut. He had always known about her insatiable sexual appetite, but hearing her speak of another man so casually was agony. He wanted to object, to beg her to reconsider, but he knew it would be futile. Heather had made up her mind, and he was at her mercy.

Heather noticed the tormented look on her husband's face, and her eyes narrowed with satisfaction. She leaned in close, her breath tickling his ear as she whispered, "You'll never be enough for me, cucky. Never. So, you might as well get used to the idea of me fucking other men. Big, strong men who can give me what I need."

Kyle's shoulders slumped, his eyes fixed on the floor as he processed her cruel proclamation. The finality of it all weighed on him, and he knew this was his new reality. He was Heather's devoted husband, utterly in love with her, and he would endure whatever she desired, no matter how much it hurt.

She had made it clear: his tiny cock and premature ejaculation had ensured his fate as a cuckold husband.
