I'm awfully ashamed with how long this has taken me.

Purple Yam Cookie stomped through the snow-covered mountains, his heavy boots crunching loudly with every furious step. His long magenta hair whipped around his face as he growled under his breath.
“Damn it… where the hell did that soft-hearted idiot run off to now?” he muttered, glaring at the endless white landscape. He and Milk Cookie had been traveling together, but somehow that fool had wandered off during the last snowstorm. Now Purple Yam was completely lost, freezing, and pissed off beyond belief.
He kept marching forward, fists clenched tight. The mountains were brutal, and the snow was getting thicker. Just when he was about to yell out Milk Cookie’s name again, something caught his eye.
A large, dark opening in the side of the mountain. A cave.
Purple Yam narrowed his eyes. “Hah… finally. Some damn shelter.” He marched straight toward it without hesitation. “Better be empty. I’m not in the mood for company.”
He stepped inside.
The cave was massive. Much larger than it looked from the outside. The air was warmer here, and a faint glow came from deeper within. Purple Yam’s boots echoed against the stone as he walked further in, still grumbling.
Then he saw you.
You rose slowly from the shadows, towering over him like a living mountain. Even sitting, you had been enormous. Standing, you were something else entirely.
Purple Yam’s eyes widened for a split second before narrowing into a furious glare.
“Who the hell are you supposed to be?” he snapped, voice loud and full of anger. “Some kind of oversized freak living out here? This is my shelter now, got it? Back off before I—”
You didn’t let him finish.
One massive hand shot out and grabbed him around the waist, lifting him clean off the ground like he weighed nothing. Purple Yam let out a furious yell as he was hoisted into the air, kicking and thrashing wildly.
“Put me down, you oversized bastard!” he roared, punching at your fingers. “I said put me down! I’ll make you regret this, you damn monster!”
You chuckled deeply, the sound rolling through the cave like thunder. “Feisty little thing, aren’t you?” Your voice was low and amused as you brought him closer to your face. “All that shouting… and yet you’re already squirming in my hand. Cute.”
Purple Yam’s face burned with rage. “I’m not cute! I’ll crush you! Let me go right now or I’ll—!”
You cut him off by pressing your thumb firmly against his crotch, rubbing slow, deliberate circles. Purple Yam’s angry shouting cracked into a sharp, involuntary gasp.
“Already getting hard,” you murmured, grinning. “All that tough talk, and your body’s betraying you so quickly. How pathetic.”
“Shut up—!” he snarled, but his voice was already breathier. You kept rubbing him through his clothes, watching with amusement as he tried (and failed) to keep fighting.
You stripped him with terrifying ease, tearing away his armor and clothes piece by piece. Purple Yam kept cursing and threatening you the whole time, but the moment your thick fingers brushed between his legs and pressed against his hole, his words faltered.
“W-wait— don’t you dare—!”
You didn’t wait.
Two of your massive fingers pushed inside him at once, stretching him open far too quickly. Purple Yam’s back arched violently as a broken cry tore from his throat. His angry growls quickly melted into strained, humiliated sounds as you worked him open, scissoring and curling your fingers deep inside him.
“Look at you,” you purred, voice dripping with mockery. “All that big talk about crushing me… and here you are, already dripping on my fingers. You’re made for this, aren’t you?”
Purple Yam tried to snap back, but all that came out was a shaky moan as you added a third finger, stretching him even wider.
By the time you finally pulled your fingers out and lined him up with your cock, Purple Yam was shaking, face flushed dark, and his earlier rage had completely crumbled.
You pushed inside.
Purple Yam’s head fell back with a raw, whine as you sank into him. The stretch was brutal, overwhelming, and far too much. His body trembled violently in your grip as you started using him — slow at first, then harder, bouncing his much smaller body on your cock like a toy.
He didn’t last long.
His angry threats dissolved into helpless, high-pitched whimpers and moans. His eyes rolled back, mouth hanging open as drool slid down his chin. By the time you finally finished, filling him to the brim, Purple Yam was completely wrecked.
You pulled out and let him drop onto the cold cave floor in a messy heap. Thick cum leaked out of him in heavy globs, pooling beneath his trembling body. His eyes were glassy and unfocused, body twitching with aftershocks.
He was barely conscious.
You looked down at the thoroughly used, dazed Purple Yam Cookie and smirked.
“Welcome to my cave, little hothead.”
....
Footsteps approached.
Dark Choco Cookie trudged through the snow toward the cave, body still aching from days of restless training and fighting. He had thrown himself into battle after battle, hoping the pain would drown out the memories. It hadn’t worked.
Every night he still dreamed of you. Every morning he woke up hard and ashamed, hating how badly he craved the very monster who had ruined him.
He hated himself for coming back.
The cave mouth loomed ahead. Dark Choco hesitated, fists clenched. I should turn around… But his feet carried him forward anyway.
He stepped inside.
The sight that greeted him made something ugly twist in his chest.
Purple Yam Cookie lay sprawled on the cave floor in a wrecked, cum-soaked mess. His muscular body was covered in bruises and thick white streaks. He looked completely fucked out.
Dark Choco’s stomach dropped.
Purple Yam? Of all people?
Jealousy hit him like a blade. Bitter, burning jealousy.
He had been here. With you.
While Dark Choco had been suffering alone, trying to forget you, this loud-mouthed excuse for a "rival" had taken his place.
His hands shook.
Purple Yam groaned weakly and cracked one eye open. Even through the daze, recognition flashed across his face.
“…Dark Choco?” he rasped, voice rough. “The hell are you doing here…?” Anger pierced through the mist of pleasure as he remembered the frustration of being defeated by him all so long ago.
Dark Choco’s jaw tightened. “I could ask you the same thing.”
Purple Yam let out a weak, bitter laugh. “Tch… figures you’d be the type to crawl back to something like this…”
Dark Choco’s face burned with shame and anger. “He doesn’t belong here…” he muttered, staring at you. “I do. I’m the one who keeps coming back. Even after everything he did to me.”
You lounged deeper in the cave, watching with clear amusement. “Well, well,” you rumbled. “Look who finally crawled back. I was starting to think you’d actually stay away this time, little prince.”
Dark Choco’s face burned hotter. “I tried,” he said bitterly. “I tried so hard to stay away. But I couldn’t. And now I come back to… him?”
You chuckled. “Jealous? Look at him. Still twitching. Still leaking. He talked so much shit when he first got here… and now he’s just a sloppy mess. Kinda like you were the first time.”
Dark Choco’s eyes flicked to Purple Yam, who was still watching them with a hazy but defiant glare.
“I’m better than him,” Dark Choco said, voice low and desperate. “I can take more. I can be better for you.”
You grinned. “Oh yeah?Then prove it.”
You leaned back against the cave wall, watching the two Cookies with clear amusement. Dark Choco stood a few steps away, breathing hard, eyes locked on Purple Yam’s wrecked body on the floor. The sight of the other warrior covered in your cum and twitching seemed to light something ugly and desperate inside him.
Purple Yam groaned weakly and pushed himself up on shaky arms. His face was still flushed and dazed, but that familiar angry fire was already flickering back in his eyes.
“Heh… that all you got, big guy?” he rasped, voice rough but still cocky. “I’ve been through worse. You think one round is enough to break me?”
You smirked.
Dark Choco’s jaw tightened. He stepped forward, voice low and strained. “He doesn’t belong here,” he said, staring straight at you. “I do. I’m the one who keeps coming back. I’m the one who can take it.”
You let out a low chuckle and pointed at Purple Yam. “Go ahead and show me, little prince. Both of you.”
You grabbed Dark Choco by the waist and lifted him effortlessly, positioning him so he was kneeling right in front of Purple Yam’s face. Then you grabbed Purple Yam and pulled him closer too, until both of them were right in front of your massive cock.
“Since you both want it so badly,” you said, voice dark with amusement, “work for it. Show me who deserves it more.”
Dark Choco’s ears burned red. He glanced at Purple Yam, who was still glaring even while clearly struggling to stay upright.
Purple Yam sneered. “Tch. Like I’d lose to this gloomy bastard.”
He leaned in first, licking a long stripe up the underside of your cock with defiant eyes. Dark Choco’s expression twisted with bitter jealousy. Without another word, he leaned in too, pressing his tongue against the other side, trying to outdo him.
You groaned appreciatively, one massive hand resting on the back of each of their heads. “Good boys… That’s it. Work together. Or fight for it. Either way, I win.”
Purple Yam tried to be aggressive about it, licking and sucking with more force, but his body was still shaky from earlier. Every time he pushed himself too hard, his legs trembled.
Dark Choco, on the other hand, was quieter — but more desperate. He took you deeper into his mouth, eyes watering as he forced himself to swallow more. Every time Purple Yam managed to get a reaction out of you, Dark Choco’s movements grew more frantic, like he was terrified of being ignored.
You let them continue for a while, watching them compete with cruel enjoyment.
Then you grabbed Dark Choco by the back of his head and pulled him off your cock with a wet, obscene pop. Strings of saliva stretched between his lips and your glistening shaft.
“Watch,” you ordered, voice low and rough.
You flipped Purple Yam onto his stomach and shoved back inside him without warning. A loud, wet schlick echoed through the cave as you buried yourself to the hilt in one brutal thrust. Purple Yam’s back arched violently, a loud, guttural moan tearing from his throat.
“Ah—! You— you bastard—! Slow— nngh— slow down—!”
You didn’t. The wet, filthy sound of your thick cock pounding into his sloppy, cum-filled hole filled the cave — loud, rhythmic plap-plap-plap mixed with the obscene squelching of your previous load being fucked deeper into him. Every thrust made his cock twitch uselessly against his stomach, leaking in weak spurts.
Dark Choco knelt right there, forced to watch. His breathing grew heavy and ragged, fists clenched on his thighs. He quickly tore off his armor and clothes to prepare.
“…That should be me,” he muttered under his breath, voice tight with bitter desperation. “I can take more than him. I’ve taken more than him.”
You glanced down at him with a smirk. "Show me.”
You pulled out of Purple Yam with a loud, wet schlorp, a thick glob of cum spilling from his ruined hole as he let out a shaky, humiliated whine.
You grabbed Dark Choco instead, lifting him like he weighed nothing and sinking him down onto your cock in one smooth, brutal motion.
A loud, wet squelch rang out as you bottomed out inside him — easier than it should have been. Dark Choco’s head fell back with a broken cry, body shaking violently, but there was almost no resistance. His hole was already loose and slick from days of secretly riding that massive dildo back in his chambers, desperately trying to mimic the stretch only you could give him.
“Fuck—! Too deep—! Ah—!” he gasped, voice cracking.
You chuckled darkly, feeling how readily he took you. “Already this loose?” you teased, voice low and mocking as you started bouncing him hard. “Been practicing without me, little prince? I wonder how that could've went, I strongly doubt you'd found someone as large as me.”
Dark Choco’s face burned with shame, but he couldn’t deny it. The wet, filthy plap-plap-plap of your hips slamming into him filled the cave, mixed with the constant obscene squelching of his well-prepared hole. His moans echoed off the walls, desperate and broken.
You grinned, gripping his waist tighter. “Ah… at least you kept yourself ready for me.”
You turned slightly so Purple Yam had a perfect view.
“Look at him,” you said to Purple Yam, voice mocking. “Look how desperate he is. He left… and still came crawling back. That’s how badly he needs this.”
Purple Yam tried to glare, but his eyes kept flicking to the sight of your massive cock stretching Dark Choco open, the wet schlick-schlick-schlick of every thrust, and the way Dark Choco’s stomach bulged with each deep plunge. His own cock twitched weakly against his stomach.
Dark Choco was falling apart fast. Every upward thrust made him let out soft, desperate, whimpering sounds. His jealousy and need mixed together until he was practically sobbing.
“Please—! Don’t— don’t give it to him—!” he gasped, voice cracking wetly. “I’m better— I can be better— just… please don’t stop— ahh—!”
You grinned and pulled him off your cock again with a loud, messy pop, setting him on his knees right next to Purple Yam. “Both of you. On your backs.”
You made them lie side by side. Then you took turns, slamming into one, then the other, never letting either of them have you for long. Every switch was accompanied by a pathetic, desperate whine and groan from the one left empty. The cave was filled with nasty, filthy sounds, loud slapping skin, wet squelching, heavy breathing, and broken moans echoing off the walls.
Dark Choco was shaking, tears pricking at the corners of his eyes from how badly he wanted you. Purple Yam’s cocky attitude had completely shattered — now he was just moaning and begging without even realizing it, voice hoarse and needy.
You kept going until both of them were overstimulated, drooling, whimpering messes, begging in their own ruined ways.
But youu had seen enough.
Purple Yam was already a trembling, cum-stained mess on the cave floor, barely able to keep his eyes open. He had tried to stay cocky until the very end, but he had failed.
Dark Choco, on the other hand, was still desperately trying to prove himself — shaking, flushed, and looking up at you with those pleading crimson eyes.
You grabbed him.
With one massive hand, you lifted Dark Choco and slammed him down onto your cock in one brutal motion. He cried out, back arching sharply as you filled him completely. His body clenched around you so tightly it almost hurt.
Purple Yam’s head jerked up weakly at the sound.
You didn’t give Dark Choco time to adjust. You fucked him hard — deep, powerful thrusts that made his smaller body bounce helplessly in your grip. Every time you bottomed out, a visible bulge pressed against his stomach. Dark Choco’s head lolled back, mouth opened in moans.
“Ah—! Too deep—! You’re— you’re splitting me—!”
You growled low, voice rough with satisfaction. “That’s right. This is where you belong. Not him,you.”
You turned slightly so Purple Yam had a clear view. The dazed warrior could only watch as you used Dark Choco with rough, possessive thrusts. Every slam of your hips made wet, filthy sounds echo through the cave.
Dark Choco’s legs kicked weakly. His cock leaked steadily against his stomach. He looked completely overwhelmed… and completely addicted.
Purple Yam tried to speak, voice hoarse and shaky. “…Bastard… he’s… he’s not even fighting back…”
You laughed darkly and slammed into Dark Choco deeper. “He doesn’t need to fight. He knows his place.”
Dark Choco let out a shaky, desperate sound. His hands clutched weakly at your fingers. “Please—! Don’t stop— I can take it— I’m yours—!”
You could feel him getting close. His walls fluttered around your cock, squeezing desperately. You kept pounding into him until his body seized up. Dark Choco came with a sheer cry, spilling across his own chest and stomach. His hole clenched violently around you.
You fucked him through his orgasm until you were close, then you pulled him off your cock with a wet sound.
Dark Choco gasped at the sudden emptiness, his hole left gaping.
You held him up and stroked yourself. With a deep, satisfied groan, you came.
Thick ropes of cum painted across Dark Choco’s stomach and chest. Some of it spilled down between his legs and dripped heavily onto Purple Yam, who was still lying right beneath him.
Purple Yam flinched as the hot cum landed on his face and chest. He let out a weak, humiliated sound.
You looked down at both of them.
Dark Choco was panting heavily in your grip, eyes half-lidded and glassy, body still twitching. He looked completely claimed.
Purple Yam lay beneath him in a ruined heap, covered in your cum. His earlier attitude was completely gone.
You smirked, but your voice was a little softer when you spoke to Purple Yam. “…You fought harder than I expected, hothead. Not bad.”
You gently lowered Dark Choco until he was cradled against your chest. One massive hand stroked slowly down his back in a rare, almost tender motion. “You did good, little prince,” you murmured, voice low and possessive. “You earned it.”
Dark Choco didn’t answer with words. He just pressed his face weakly against your skin, breathing hard, completely spent but clearly satisfied.
You glanced back down at Purple Yam. He was still twitching and leaking, looking thoroughly wrecked. After a moment, you reached down with your free hand and gave his messy hair a surprisingly gentle ruffle. “Next time you wander into my cave… maybe don’t challenge the one who already belongs here.”
Purple Yam let out a weak, defeated groan, but didn’t try to snap back.
You leaned back against the cave wall, still holding Dark Choco close. Both subs were thoroughly used and marked — but Purple Yam had been given at least a small sliver of mercy at the end.
A slow, satisfied grin spread across your face.
This cave was yours.
