Chapter 9: The Mule Cock
The silence that followed Kan's words was thick enough to cut. He felt the weight of his own confession hanging in the air—that raw, desperate admission that he wasn't done, that he would never be done—and watched as something shifted in Rei's eyes. The exhaustion that had been creeping in moments before evaporated, replaced by a renewed hunger that made Kan's breath catch.
"You're going to kill me," Rei said, but there was no complaint in his voice. Only wonder.
"Not yet." Kan pushed himself up, wincing at the ache in his stretched hole, the trickle of come still leaking down his thighs. "I have plans for you."
Rei laughed, low and dark. "Is that right?"
"Mm." Kan walked to the bedside table on unsteady legs, his fingers closing around a small velvet pouch he'd hidden there earlier. "I got this from a friend of Visanu's. A little experiment."
"A friend of—" Rei's eyebrows shot up. "You've been talking to Visanu behind my back?"
"Not behind your back." Kan turned, holding up the pouch. "He introduced me to someone. A man who runs a private club. Very exclusive. Very... extreme. He gave me this as a taste of what's to come."
Rei's gaze sharpened. "What is it?"
Kan opened the pouch, revealing a small glass vial filled with a viscous, shimmering liquid. It caught the lamplight, refracting it into strange, iridescent patterns that danced across the ceiling mirror.
"I don't know exactly," Kan admitted. "He said it's a serum. A cocktail of ancient herbs and modern science. Said it would enhance everything. Make me feel things I've never felt before." He paused, his voice dropping. "Make you bigger."
Rei's eyes widened. He sat up, the sheets pooling around his waist, his spent cock stirring at the implication. "Bigger?"
"Much bigger. He showed me pictures. Before and after. The results were..." Kan licked his lips. "Impressive."
"And you trust this?" Rei asked, his voice careful. "Some stranger from a club you've never been to?"
Kan shrugged. "I'm still here, aren't I? He didn't ask for money. Didn't ask for anything. Just said to try it, and if I liked it, we could talk." He held the vial up, watching the liquid swirl. "I like living dangerously. You know that about me."
Rei was quiet for a long moment, his eyes fixed on the glowing liquid. Then he reached out, taking the vial from Kan's hand.
"If this goes wrong, I'm holding you responsible."
"If it goes right," Kan countered, "you'll be thanking me."
Rei uncorked the vial. The scent that wafted out was strange—earthy and sweet, like crushed flowers mixed with something metallic. He hesitated, then tipped it back, swallowing the contents in one gulp.
The effect was immediate.
Rei gasped, his body convulsing as if struck by lightning. His back arched, muscles straining, and Kan watched in horrified fascination as Rei's cock began to swell. It grew thicker first, expanding in girth until it was nearly twice its normal width. Then it lengthened, extending inch by inch until it hung heavy and obscene between Rei's thighs, a monstrous member that seemed impossible, grotesque, magnificent.
"Fuck," Rei breathed, staring down at himself. His voice was strained, thick with the effort of containing whatever was coursing through him. "Fuck, Kan, it's—"
Kan's eyes were wide, his mouth dry. Rei's cock was enormous now, easily as thick as his own wrist and nearly as long as his forearm. The head was bulbous and swollen, a deep purple against the engorged shaft, pulsing with a heartbeat of its own. Precome oozed from the slit in thick, glistening ropes, pooling on Rei's stomach.
"Christ," Kan whispered. "That's... that's insane."
Rei's hands came up, gripping the shaft. He stroked himself, a low groan escaping his lips at the stimulation. "It feels... I can feel every heartbeat. Every pulse. Fuck, it's so sensitive—"
Kan's own cock, still soft and spent from their previous encounter, began to stir at the sight. A perverse hunger gnawed at his gut. He knew he should be terrified. That thing would never fit. It would tear him apart.
But the thought only made him want it more.
"Can you move?" Kan asked. His voice was hoarse.
Rei nodded, sliding off the bed. He stood, the monstrous cock swinging heavy between his legs. When he walked toward Kan, it swayed with each step, hypnotic and menacing.
"You're not actually going to try—"
"Shut up." Kan's hands came up, wrapping around Rei's cock. He couldn't even close his fingers fully; his grip spanned barely two-thirds of the girth. The skin was hot and silky, stretched taut over the engorged flesh. He stroked upward, watching more precome spill over his fingers. "I need this inside me."
"Kan, you'll split in two."
"Then I'll die happy." Kan dropped to his knees.
He took the head into his mouth with effort, his jaw screaming at the strain. The taste was overwhelming—salt and musk and something strange, chemically sweet from the serum. He worked his lips around as much as he could, using his hands to stroke the rest, but even combined it was too much. His mouth was stuffed beyond capacity, saliva dripping down his chin, and he still couldn't take more than half of the head.
Rei was trembling above him, fists clenched at his sides. "Kan—if you keep doing that, I'm going to come—"
Kan pulled off with a wet gasp. "Not yet. I want it inside me first."
"You can't be serious—"
But Kan was already turning, bending over the bed and presenting his sore, stretched hole. He reached back with both hands, spreading his cheeks, showing Rei the damage from earlier—the gaping, pink entrance, still wet with come and lube.
"Make it fit," Kan demanded.
Rei moved behind him, positioning that monstrous head against Kan's entrance. Even just the pressure of it made Kan gasp—it was like a fist pressing against him, unyielding and huge. But he pushed back, trying to force himself onto it.
"Fuck—" Rei's voice was tight. "I can't—you're not open enough—"
"I don't care," Kan growled. "Fuck me. Fuck me until I'm open enough."
Rei's hands gripped his hips, nails biting into the skin. He pushed, and Kan felt the head begin to breach him, stretching him beyond anything he'd ever experienced. Pain lanced through him, white-hot and blinding, and he screamed—not in protest, but in sheer, overwhelming sensation.
"That's it," Rei groaned, his voice strained. Another inch gave way. "Take it. Fucking take it—"
Kan's vision was swimming. The stretch was obscene, impossible. He could feel his body being forced open, each inch of Rei's massive cock spreading him wider and wider. The pain was excruciating, but beneath it, buried deep in his gut, a blossoming pleasure was beginning to bloom.
"I'm barely half in," Rei said, his voice shaky. "Gods, Kan, I can see myself through your skin—"
Kan looked down. His belly was slightly distended, the outline of Rei's cock visible beneath his skin. The sight made him moan, a desperate, wanton sound. "More. Give me more."
Rei pushed deeper.
Kan's screams echoed off the walls. Tears streamed down his face, but he was pushing back, meeting each inch of the invasion. His own cock, soft before, had come to rigid attention, leaking against his belly, heedless of the pain his hole was enduring.
"I'm all the way in," Rei said, his voice barely a whisper. He was buried to the hilt inside Kan, his pelvis flush against Kan's ass. The bulge in Kan's stomach was unmistakable now—a thick, obscene ridge pressing against his abdominal wall.
"Fuck you," Kan sobbed. "Fuck you, that's—that's so much—"
Rei held still, giving Kan time to adjust—or at least, time for the pain to dull. Kan's body quivered around him, the impossible stretch sending shockwaves of sensation through him. It hurt. Gods, it hurt more than anything he'd ever felt. But it also felt incredible. He felt so full, so completely and utterly filled that nothing else in the world existed.
"Move," Kan begged. "Please, Rei, move."
Rei began to thrust.
The first stroke was shallow, a slide of perhaps an inch, but it sent a jolt through Kan's entire body. The second went deeper. The third deeper still, until Rei was moving in and out with long, devastating strokes that left Kan gasping, clutching the sheets for anchor.
"I feel you everywhere," Rei groaned. "Every inch, I can feel it, all of you, so tight around me—"
Kan couldn't respond. His voice was gone, reduced to hoarse, panting cries with each impact. His hole was being demolished, stretched to proportions he'd never imagined possible, but his cock was hard as iron, leaking freely. The pleasure was building, coiling deep in his belly, mixing with the pain until he couldn't tell them apart.
"I'm going to come," Rei warned. His pace was increasing, becoming frantic, animal. "I can't hold it anymore—"
"Do it," Kan gasped. "Come inside me. Fill me up—"
Rei slammed home one final time, his hips grinding against Kan's ass, and Kan felt the impossible sensation of Rei's cock swelling even further, then releasing. It was like a dam breaking. Hot, thick come flooded him, filling him to the brim and beyond, overflowing and dripping down his thighs. The sensation was so intense, so overwhelming, that Kan felt himself teetering on the edge of consciousness.
And then, without warning, his own orgasm ripped through him. His cock erupted, spraying release across the sheets, while his hole clenched and spasmed around Rei's still-throbbing length. It was too much—everything was too much. His eyes rolled back, his body convulsing violently.
He felt something else let go. A warm, liquid sensation spreading beneath him as he lost control of his bladder, pissing himself in an unstoppable flood. The warm stream saturated the sheets, mixing with his come and sweat, and he screamed—a raw, guttural sound that was equal parts humiliation and ecstasy.
"Fuck," Rei breathed, his voice reverent. He was still inside Kan, still buried to the hilt, and he could feel every pulse of Kan's release around him. "Fuck, Kan, you're so perfect. So fucking perfect—"
Kan collapsed, his body limp, barely conscious. He was a wreck—bruised and stretched, covered in his own fluids, his hole ruined and gaping around Rei's monstrous member. But he was alive. More alive than he'd ever been.
Rei didn't pull out. Instead, he lifted Kan's limp body, turning him onto his back and settling him on the bed. The motion kept Rei's cock buried inside him, shifting and grinding against Ka's inner walls. Kan whimpered, barely conscious, but he didn't protest.
"I'm not done with you," Rei murmured, stroking Kan's sweat-soaked hair. "I'm going to stay inside you all night. Keep you stuffed and full."
He moved, settling himself more fully on top of Kan, his weight pressing down. His cock remained buried, a thick, pulsing presence that Kan could feel in every fiber of his being. Then Rei's hand found the bulge in Kan's stomach—the outline of his own cock pressing against Kan's abdominal wall—and he began to stroke it.
The sensation was unbearable.
Kan's eyes flew open, and he gasped, his body jerking. Rei's fingers traced the ridge of his own cock through Kan's skin, a ghostly caress that sent waves of pleasure cascading through him. It was like being touched from both outside and inside, a sensation so alien and intense that Kan felt his consciousness splinter.
"Please—" Kan sobbed. "Please, Rei, I can't—"
But Rei didn't stop. He continued stroking the bulge, tracing the outline of his cock as it shifted and moved inside Kan. Each touch sent a fresh wave of pleasure through Kan's exhausted body, drawing out his depleted reserves, forcing him to feel more, always more.
"You can take it," Rei whispered. "You were made for this. Made to take everything I give you."
Kan's body trembled, his hole clenching weakly around Rei's cock. He was so sensitive, so overwhelmed, that he felt like he was drowning. But Rei's words anchored him, kept him grounded in the reality of the moment.
He was filled. He was used. He was utterly, completely claimed.
And as Rei's hand stroked his belly, again and again, Kan felt himself spiraling into a pleasure so deep that he lost all sense of himself. The room faded. The sounds faded. There was only Rei. Only the fullness. Only the impossible, endless pleasure of being so thoroughly and completely taken.
The world narrowed to that single, profound truth.
When morning came, the lanterns had burned out, leaving the room in gray pre-dawn light. Rei was still inside him, still hard, still watching him with that dark, possessive gaze. Kan trembled beneath him, wrecked in ways he couldn't articulate.
"Visanu's friend," Kan managed, his voice a ruined whisper. "Send him a message. Tell him... tell him I'm very interested."
Rei smiled, slow and dangerous.
The outline of his cock shifted inside Kan as he leaned down to kiss him, and Kan sighed into the embrace. He was exhausted, but he was also alive—burning and bright. His journey was just beginning.
The kiss broke only when the hunger returned, a sharp pull low in Kan's gut that had nothing to do with exhaustion. Rei's cock had softened inside him but refused to slip out, a thick, insistent anchor keeping them tethered long past the point of sanity. Kan's hand drifted down, fingers brushing the ridge of his own stomach, feeling the faint outline beneath his skin, and he shuddered.
"You're still inside me," Kan whispered, half in wonder, half in accusation.
Rei's laugh was a low rumble against his chest. "You're still taking me. I'm not sure I could pull out even if I wanted to. The serum needs time to wear off."
Kan's eyes widened, a dark thrill threading through his veins. He shifted his hips experimentally, feeling the thick length slide against his abused walls, and gasped. "How much time?"
"Hours, maybe." Rei's voice dropped. "All morning, possibly."
Kan's body convulsed with a need he couldn't name. The pain was still there, a dull, throbbing ache in his stretched hole, but it had transmuted into something else—a craving, a desperate hunger that had him grinding down on every inch of the impossible cock filling him.
"Then you're going to need to keep yourself entertained," Kan said, his voice gone hoarse. "Because I'm not letting you leave this bed until you've fucked me into a coma."
Rei's eyes flared with heat. "You're going to be the death of me, you little slut."
"You love it."
"I do." Rei pressed a hard kiss to his lips, then pulled back. "But this time, I want you to do the work. Ride me. Show me how much you want it."
Kan's pulse quickened. His body screamed in protest at the thought of moving, but the hunger overrode it. He pushed himself up, arms shaking, and eased himself onto his knees. The motion forced Rei's cock deeper inside him—impossible, since he was already buried to the hilt—and Kan felt something in his gut shift, a new depth being reached.
"Holy fuck," Kan breathed.
"That's it," Rei coaxed. "Take me. Use me. Make yourself feel good."
Kan began to move.
The rhythm was slow at first, tentative. Each rise was a deliberate effort, his sore muscles screaming, his stretched hole clenching around the enormous girth. Each fall was a revelation, the thick head grinding against his prostate, sending sparks of lightning through his belly. He was so full, so impossibly, achingly full, and it was perfect and terrible and magnificent.
"Faster," Rei commanded. "Take me faster."
Kan obeyed. His hips snapped forward, finding a rhythm, each movement becoming more urgent. Sweat slicked his skin, making his thighs slide against Rei's hips. The sounds that filled the room were filthy—wet, obscene, the sound of his body swallowing Rei's cock again and again.
"Like that," Kan gasped. "Fuck, yes, exactly like that—"
Rei's hands came up, gripping Kan's waist, helping him move. The pressure changed, and Kan cried out as the new angle drove even deeper. His vision whited out, and he was distantly aware of his own come streaking across Rei's chest, a fresh wave of release tearing through his body.
"Don't stop," Rei said, his voice strained. "Keep going. Let me feel you come apart."
Kan kept moving, though his legs trembled and his arms ached. He was reduced to a single point of contact—the place where they joined, where he was spread wide and stuffed full. Everything else fell away. The room, the light, the sound of his own heartbeat pounding in his ears. All of it dissolved into the overwhelming reality of being filled.
"I'm close," Rei warned. "Kan, I'm going to come—"
"Inside me," Kan demanded. "Fill me again. I want to feel it."
Rei's hands clamped down on his hips, and his body went rigid. Kan felt the first hot gush, a flood of liquid that seemed to go on forever, filling spaces he hadn't known existed. The sensation tipped him over the edge, and he came again, a helpless, pitiful thing, his body convulsing around Rei's cock as he lost himself completely.
The room swam back into focus slowly, the colors bleeding back into the gray. Kan collapsed onto Rei's chest, trembling, his hole still stuffed and overflowing. Rei's cock remained buried inside him, still hard and already twitching with renewed hunger.
"Your heart is racing," Rei murmured, pressing a kiss to Kan's temple.
"I think I just died a little," Kan confessed. "And came back."
Rei chuckled. "I think you might be immortal. No one else could take what I just gave you and still be breathing."
Kan's lips curved into a tired smile. "Is that your way of saying I'm special?"
"It's my way of saying you're the most goddamn incredible thing I've ever had the misfortune to fall for."
Kan's heart, already pounding, seemed to skip a beat. He looked up at Rei, searching his face for any hint of the joke, but all he saw was raw, unfiltered truth. A vulnerability he'd never glimpsed before, laid bare in the half-dark.
"Fall for," Kan repeated. "You've fallen for me?"
"Like a goddamn tree in a forest," Rei said, his voice rough. "No warning, no grace. Just—broke in half the moment I saw you."
Kan didn't know what to say. The words felt too big for the room, too big for the bed they were tangled in, too big for the moment in time they occupied. But they settled in his chest with the weight of absolute truth, meaning, rooting into the spaces he hadn't known were empty.
"I think," Kan started, then stopped. His voice cracked. "I think I might have fallen too."
Rei's expression—guarded, brittle—softened. He pulled Kan into a kiss so gentle compared to what they'd just done, a tender brush of lips that felt new, fragile. When they broke apart, Rei's thumb traced his cheekbone.
"Then we're a pair of idiots," Rei said. "Two fools who found each other during the worst impulses of our lives."
"Speak for yourself," Kan said, but his voice was watery. "I've made some great decisions lately. Getting that serum was a stroke of genius."
Rei snorted. "Getting that serum nearly killed you."
"But what a way to go."
They laughed, the tension breaking, and Kan settled more comfortably against Rei's chest. The cock inside him had finally softened, and he felt a pang of loss, then a strange satisfaction as it slipped out. His hole gapped, wet and loose, a testament to the night's excesses.
"I'm going to call Visanu today," Kan said, his voice sleepy. "Tell him I want to meet his friend."
"Now?" Rei's voice held a note of surprise. "You just told me you were dying."
"I said I died and came back. There's a difference." Kan yawned, pressing his face into Rei's shoulder. "I meant what I said before. I'm interested in what he has to offer. I want more."
"More of what? More serum? More pain?"
"More feeling." Kan's voice was soft. "More losing myself. More of that edge where I don't know if I'm coming or going or waking or dreaming. Nothing in my life has ever made me feel as alive as you did tonight."
Rei was silent for a long moment. Then his arms tightened around Kan, pulling him closer.
"Then I'll take you to meet him," Rei said. "But I'm staying with you. Every step."
Kan smiled, a slow, genuine curve of his lips. "I wouldn't have it any other way."
Morning came too quickly. Kan woke to the sound of Rei's phone buzzing on the bedside table—a harsh, insistent vibration against the wooden surface. He groaned, burying his face in the pillow, feeling every ache and pain from the night before.
"Get it," Rei mumbled, his voice thick with sleep. "Might be important."
Kan dragged himself out of bed, his legs wobbling. He grabbed the phone, squinting at the screen. The contact name made his heart skip.
"Visanu Harin."
Rei sat up sharply, his eyes snapping open. "What does he want?"
Kan swiped to answer, putting the phone to his ear. "Visanu. You're up early."
The voice on the other end was smooth, cultured, faintly amused. "Kan. I hope I'm not interrupting anything... delicate."
"Only if you consider running a marathon while being stretched wide a delicate activity."
Rei snorted in the background, covering his mouth with his hand. Visanu's laugh came through the line, warm and knowing.
"Your bluntness is one of your most endearing qualities. I'm calling because my friend is eager to meet you. He heard about your little... experiment last night."
Kan's pulse quickened. "How did he know about that?"
"You were given the serum as a gift," Visanu said. "He asked me to check on the results. You appear to be intact, if slightly ruined."
"I told you I wanted more." Kan's voice was steady. "I meant it."
"Patience, Kan. You'll have your chance. He wants to meet you in person before he decides if you're ready. He's particular about who he introduces to his inner circle."
"Where and when?"
"Tonight. Ten o'clock. A club called the Crimson Garden. It's in the old quarter, near the river. Come alone."
Kan's gaze flicked to Rei, who was watching him with an unreadable expression. "I can't come alone."
"Why not?"
"Because I promised I wouldn't."
There was a pause. Then Visanu laughed, a light, melodic sound. "How romantic. Very well. Bring your lover. He would like to meet you both. But understand this, Kan—if he's not suited for what's to come, this will end before it begins. Not everyone is cut out for the deeper circles."
"We'll take that chance."
"Then I'll see you tonight." The line went dead.
Kan lowered the phone, his heart hammering. Rei was standing now, moving to his side, his hand settling on the small of Kan's back.
"What was that about?"
"He wants to meet us tonight. The Crimson Garden." Kan turned to face Rei. "He sounded—expectant. Like he already knows something about us."
Rei's jaw tightened. "I don't like this. It moves too fast."
"Maybe that's the point." Kan's voice was low. "Some things you can't plan for. Some things you just have to trust."
Rei stared at him for a long moment, searching his eyes. Then he pulled Kan into his arms, holding him tight.
"Whatever happens tonight," Rei said, his voice barely a whisper. "I'm with you. Every step."
"I know." Kan pressed his face into Rei's neck, breathing in the familiar scent. "I know."
They spent the day in silence, moving around each other with a quiet intimacy that felt new and fragile. They ate cold noodles from the market, drank iced tea on the balcony, and watched the sun crawl across the sky, tracking its progress with growing unease.
By the time the evening arrived, Kan's nerves were singing. He dressed carefully—black silk shirt, loose-fitting pants, a silver chain that caught the light. Rei matched him in dark linen, the knife he always carried strapped to his ankle.
The Crimson Garden was easy to find. Nestled in the narrow alleys of the old quarter, its entrance was marked by a single, blood-red lantern casting a pool of light onto the cracked pavement. Kan hesitated at the threshold, then pushed the door open.
The interior was a world apart—a lavish, dimly lit space filled with velvet booths and antique lamps. The air hung heavy with sandalwood and something else, something metallic and faintly sweet, like the scent of a wound.
A man sat at the far end of the room, backlit by a single lamp. He was older than Kan had expected—perhaps in his late forties—with silver-threaded black hair and a face carved from sharp angles. His gold-flecked eyes studied them with a predator's patience.
"Kan," he said, his voice a warm, resonant rumble. "Rei. I've been expecting you."
Kan's steps echoed as he crossed the room, Rei a solid presence at his side. The voice was familiar, the same smooth cadence from the phone call, though deeper in person.
"You're Visanu's friend, then. The one who calls the shots."
The man—his name still unspoken—inclined his head. "I am called Phra Chan. I own this place, and several others like it. Your... exhibition last night was impressive. Few survive their first encounter with the serum."
Rei's hand pressed against his lower back, a subtle warning. Kan understood the message—be careful, don't trust him—but keep talking.
"I've been told you have more to offer me."
"I have everything to offer you," the man said. He gestured to the booth across from him. "Sit. We have much to discuss."
The booth swallowed them in velvet as they slid in. Phra Chan's gaze was almost a physical weight, assessing their every move.
"Your friend Visanu has told me about you both," Phra Chan continued. "About your appetites. Your... exploration. He says you have a hunger that is not yet sated."
Kan's heart hammered. "He's right."
"Hunger can be a dangerous thing if left unchecked. It can consume you, or it can make you into something extraordinary. The question is which you will become."
Kan met Phra Chan's gaze, defiance edging into his voice. "I've never backed down from a challenge."
Phra Chan's smile was slow, like silk over steel. "No. I don't think you have." He rose from his seat, crossed to a cabinet, and returned holding a small black case. He set it on the table between them. "This is a gift. Not a test. Not a challenge. Just a... demonstration of what I can offer."
He opened the case. Inside, nestled in black velvet, lay a collar of hammered silver and a pair of steel cuffs, each inlaid with intricate patterns that seemed to writhe in the lamplight.
"These were made by a master craftsman," Phra Chan said. "They have been worn by kings and queens of the underworld—those who understand that true surrender is the greatest power of all."
Kan's fingers brushed the metal. It was cool, smooth, heavy with meaning.
"What would you have me do with these?" he asked, voice carefully even.
"Wear them," Phra Chan replied. "Tonight. And prove to me you are worthy of the next circle."
The air in the room thickened. The pulse in Kan's throat beat hard.
"More," he whispered. "Please. I want more."
Phra Chan's smile widened.
"Then take them. And let us begin."
