Birthday Rage and Simmering Betrayal
On Woo-hyun's birthday, Eun-ho was locked in a brutal internal battle—wanting to charge in right then and there, yet craving just a little more time to watch. His mind was a mess. Rage surged up only to be swallowed by a scorching heat rising from his gut. Thoughts of storming over and grabbing Woo-hyun by the collar clashed with the urge to stay rooted to the spot, not moving an inch. His nails dug into his palms. He gritted his teeth. But his feet wouldn't budge.
Even as his head spun without resolution, Woo-hyun's cock kept plunging relentlessly in and out of Ye-rin's pussy.
"Ahng... haang... ahng... ahng... haang..."
"Quiet down a bit... what if someone hears us?"
"Haht... I don't care... ngh... cover... my mouth..."
At her words, Woo-hyun grabbed Ye-rin's chin, turned her face, and kissed her.
"Ngh... mmph... churp... chup... ngh... hngh..."
Eun-ho hadn't even touched his dick, but he felt ejaculation building. If he didn't hold back, he'd cum for real. Inside his training pants, his cock throbbed wildly. More shocking than Woo-hyun entering Ye-rin's pussy was Ye-rin begging for the kiss first, the two of them locking lips. He'd thought they were just fuckbuddies sharing bodies, but this felt deeper.
"Mmph... chup... hnght... churp..."
And right in front of Eun-ho, he could see Ye-rin's tongue getting sucked into Woo-hyun's mouth. Saliva stretched and snapped between their lips over and over. Ye-rin was never that aggressive with Eun-ho's kisses. She'd only timidly offer her tongue if he sucked first. But now, she was shoving hers deep into Woo-hyun's mouth. His fist clenched harder. And at the same moment, he felt his underwear growing soaked. Precum was leaking out more and more.
"Haa... haa... ngh... Woo-hyun... harder now..."
"Got it... just hold back the noise..."
Thwack! Thwack! Thwack!Thwack! Thwack!
Woo-hyun gripped Ye-rin's waist and started slamming his hips in earnest. The sound of flesh slapping echoed through the forest. Eun-ho could see Woo-hyun's small cock pulling almost all the way out before plunging back in. Even the white cream from Ye-rin's juices coating Woo-hyun's shaft.
Eun-ho wanted to whip out his dick and jerk off right now. Separate from the anger, his cock felt ready to burst. He barely suppressed the impulse to press down on the bulging tent in his pants. She'd been his childhood friend his whole life. Always pure and shy. And around Eun-ho, she'd always shown only that side. Seeing that Ye-rin panting on another man's cock drove him insanely aroused. Begging for it harder, demanding he cover her mouth with a kiss first. This was Ye-rin he didn't know.
Eun-ho wanted to deny himself. In a situation where he should rage, separate them, and beat Woo-hyun down, why was he like this? He couldn't understand. But he couldn't tear his eyes away.
"Ye-rin... I... I'm gonna cum..."
"Ahht... hnght... no... ah... no... not inside..."
"Why? Again?"
"Haang... ahng... Eun-ho's training... ahht... ends today..."
"Oh... ugh... today? Fine... ugh... cumming... take it in your mouth..."
Ye-rin quickly spun around and took Woo-hyun's cock in her mouth. She bobbed her head back and forth, urging his release. Eun-ho let out a hollow chuckle at the sight. He always begged Ye-rin for blowjobs, but she rarely obliged. His dick was too big, she said—it hurt her jaw. Yet here she was, sucking Woo-hyun's so naturally. Hands gripping his thighs, head moving rhythmically. It was practiced. Not a one- or two-time thing.
Fuck...
Chup... churp... chup... chup... churp...
The sounds of Ye-rin slurping Woo-hyun's cock reached Eun-ho's ears. In the quiet forest, they rang out crystal clear.
"Ugh... cumming... drink it all..."
Ye-rin's movements stopped, and Woo-hyun's body twitched. Eun-ho saw it all. After Woo-hyun shuddered, Ye-rin's throat bobbed. Once, twice, three times. Each gulp sent Woo-hyun's cum down her throat.
Even when Ye-rin blew him, she hated cum in her mouth. Once, he'd accidentally shot inside, and she'd spat it out with a teary face. But Woo-hyun's cum? She was swallowing it like it was delicious.
That fucking bitch...
Eun-ho bit his lip hard. Blood trickled down, but he didn't notice. The metallic taste spread on his tongue, but he was too lost in the scene. And he couldn't hold back anymore. Just touching his dick now would make him cum. These clashing emotions and sensations were driving him mad. Rage boiled, yet his cock hardened more; he hated Ye-rin, but couldn't look away.
Even after Woo-hyun finished, Ye-rin kept his cock in her mouth. Probably cleaning it off after swallowing every drop. Eun-ho could sense her tongue swirling the head even in the dark.
Ye-rin was giving Woo-hyun everything she denied Eun-ho. He felt empty. He had no idea how to deal with Ye-rin and Woo-hyun to shake this off. But what Woo-hyun said next crushed him even more.
"Hoo... that was fucking amazing... Ye-rin... Seo-yeon wants to do it together again soon, you cool? Eun-ho'll be around on my birthday, so maybe the next day?"
Only then did Ye-rin release Woo-hyun's cock from her mouth and reply.
"All three of us? Again? Won't you get tired?"
"Nah... with you two, I could go till I die..."
"What? Last time you only came three times..."
"Not this time. You'll see."
"Dunno... depends if Eun-ho's free after training today... I gotta take care of him..."
"You can make time... right?"
"We'll see later..."
"You better."
From the conversation, Eun-ho pieced it together. Woo-hyun had fucked Seo-yeon and Ye-rin together. More than once. His teeth ground. But the rage wasn't at Woo-hyun or Ye-rin. It was at Seo-yeon, who'd never breathed a word despite fucking Eun-ho herself. No, she'd joined in. Before punishing Woo-hyun and Ye-rin, his mind filled with thoughts of dealing with Seo-yeon first.
While Eun-ho stewed, Woo-hyun and Ye-rin straightened their clothes, held hands, and left the forest. Ye-rin leaning her head on Woo-hyun's shoulder was the last image. Eun-ho stared until they vanished. Alone in the dark, his pants were drenched in precum.
Eun-ho did nothing for days after. Even meeting Ye-rin, he didn't fuck her. She eyed him curiously, but he smiled like nothing was wrong. He brushed her hair, ate with her, held her hand as usual. But his mind never quieted. Nightly, the forest scene replayed, heating his gut each time.
And Woo-hyun's birthday arrived. Normally, he'd celebrate his lifelong buddy wholeheartedly, but now he was pissed at Woo-hyun. Still, his best friend versus the guy toying with Ye-rin left his head spinning. The conclusion was simple: Woo-hyun was irreplaceable.
The four gathered in Woo-hyun's dorm room. A small cake, drinks flowing. The cramped space meant knees touched when they sat. Cross-legged on the floor, they downed soju shots. Snacks and dried sides littered the center. Two soju bottles were already empty. The cake candles had melted, staining the cream.
"Here, bro... happy birthday."
Eun-ho gifted a solid-brand wrist brace.
"Nice... how'd you know I like this brand? Thanks, man."
Woo-hyun grinned, trying it on. Eun-ho swallowed complex feelings at that smile.
Seo-yeon and Ye-rin gave their gifts too. Eun-ho smirked bitterly seeing Ye-rin double up. She'd already given Woo-hyun his "present" in the forest two days ago, yet here she was handing over wrapped gifts, blushing shyly, oblivious to Eun-ho's gaze.
The drinking stretched on. With long histories minus Seo-yeon, stories flowed endlessly—from old memories to campus gossip. As soju circulated, voices grew louder, laughter more frequent.
"So basketball has guys and girls playing naked?"
"Yeah... it's insane. During games, guys press up defending, cocks sliding between thighs..."
"Who the fuck? I'll kill 'em."
Woo-hyun fumed at the thought of other guys touching Seo-yeon. Eun-ho scoffed inwardly.
"Dude, where in this school doesn't that happen? It's all the same..."
"Still, shoving dicks in? Seo-yeon, ever had one slip in?"
"What? No... it doesn't just happen. Clench and you're fine."
"Hoo... still pisses me off."
"And your tennis club does naked matches with girls too, right?"
"No mixed matches for us. Even if, bodies don't touch much in tennis."
"Fair... kinda wholesome sport."
"What about judo?"
"Separate dojos."
"Oh right."
"Swim team's like? Didn't you say punishments ended after last year's thing?"
Seo-yeon asked Ye-rin.
"They did... but restarted recently. Records suck lately."
"Back to naked mixed swims?"
"Not everyone... just the ones with bad times."
"You got good times then?"
"Uh... sorta..."
Ye-rin trailed off, sipping soju and averting eyes. Eun-ho knew why: to avoid creampies before naked swims, he'd told her no insides.
Club secrets were supposed to stay secret, but after a year-plus at Donghae Comprehensive Sports University, most were open ones. Punishments here were mostly naked. Girls stripping before guys was routine. Led to low barriers for mixed sex. That's how Eun-ho fucked so many. But he'd never imagined his own girl getting fucked—recently realizing his naivety.
That unclear mix of rage or thrill bubbled again. Happened every time he saw Ye-rin lately. Her smiles overlaid with her forest face, cock in mouth. Eun-ho swallowed it deep, chatting nonsense as night fell outside.
