Cheol x Gyu header

 

 

👨👦

 

Nearly a year after Cheol's dad passed away, his mom married a widower: Mr. Kim. Seungcheol was a wee lad when his mom remarried. He grew up knowing that Mr. Kim was his real dad. The couple's union brought forth a son, and they named him: Mingyu.

 

Mr. Kim was a fantastic father! He and Mrs. Choi, now Mrs. Kim, raised the boys in a VERY religious setting. It has its pros and cons. Growing up in a spiritual family, stepbrothers; Cheol and Mingyu never had a feel of the natural world until they both left their homes for university.

 

Seungcheol moved out first. He stayed within the campus, having that fun dorm life— this was a blessing for Cheol. 

 

Though his parents were great, they were not that open-minded. That is why Cheol never came out to them, or at least not yet. 

 

He always knew that he was gay. The only person he could be open to was his younger brother: Mingyu. Who wholeheartedly accepted and supported him.

 

— Cheol and Gyu were inseparable! They did everything together; played ball, listened to the same music, watched similar shows, and even aimed for the same university.

 

And now that Cheol was free to be himself, taking all his bottled-up desires, your boy did not even hesitate to explore the extent of his sexuality the moment he set foot on campus! Seungcheol did what he has always wanted to do, even dying his hair BLONDE.

 

In his first year, Cheol began sleeping with men. Although he went up against his family's beliefs, Seungcheol cannot deny that he was living his best life!

 

He had a lot of self-discoveries, from kinks, sex toys, and preferences with his "bedfellows." But what stood out the most was the day he learned he was a top: and an excellent one at that! Most of his intimate pals say he's good in bed and gifted in the size department!

 

That said, Cheol's curiosity struck when he made a handful of his partners orgasm untouched. He thought that perhaps, there is a specific pleasure that bottoming gives that tops miss out on. It led him to experiment with a few varsity friends, Jun and Joshua, who were down for anything.

 

Yes, even if Cheol was uncomfortable bottoming. He was willing to make an exemption. He asked his two close buds to top him on separate occasions. Sex with those dudes was not that bad. Yet, Cheol could not enjoy bottoming for them during their friendly escapade. 

 

However, Jun and Joshua did note that he had an immaculate ass! Saying it was the best they ever fucked, adding that it was a shame the blonde did not bottom. Cheol appreciated their compliment but was dissatisfied overall. Maybe, they chose the wrong positions? Maybe Jun or Joshua was clueless? Or possibly something else?

 

Cheol was adamant about discovering that specific bottom pleasure even if his initial attempts failed. He'll get there soon... All in time!

 

 

It was not long till his first year passed when he received the excellent news that his younger brother had successfully entered the same university! As close as they were, the two shared the same dorm room. Their folks loved this idea as well.

 

Cheol was genuinely worried at first since Mingyu's arrival. He knew he needed to find a new place for his sexcapades. Nevertheless, being as witty and resourceful as he is, Cheol immediately discovered new places to do it with all his fuck-buddies.

 

Months passed, and Cheol remained discreet. Mingyu did not notice a thing, even if they shared the same space. He never knew how talented, knowledgeable, LIBERAL, and fantastic his older brother was in the sex department. Till one fateful rainy night—

 

~

 

🗲Thunder bellows outside🗲

 

As usual, Cheol returns to their dorm room, unlocks the door, calling out his brother, expecting to have a whiff of the younger's cooking; this was their usual situation. But the lights were off.

 

The only illumination sources came from the window (raindrops drumming on the glass) as the faint moonlight attempted to fill their room with soft light, and the other light source came from the TV. Some random Sci-Fi show was on.

 

The door locks close. Then it hit; there was no delicious scent of food in the air. Cheol casts his eyes, wondering why it was dark when it landed on his brother's broad back. Mingyu was sitting on the sofa.

 

Dorm Room

 

Cheol dropped his bag at a corner and sat beside his stepbro, "Hey dude, why are the lights off—" he was suddenly distracted to see a standard Durex condom with a tear in Mingyu's hands, its foil wrapper on the floor.

 

"Uh, Gyu? What's going on?" Cheol noticed now that his little brother was nude from the waist down, with only a white shirt on, and eyeing their blue university throw pillow covering the younger man's crotch.

 

"It's, it's em-embarrassing…" Mingyu focused on the torn, thin latex.

 

An arm wrapped around his bro's shoulder, Cheol comfortingly reassures, "Hey, hey… It's just me." nudging his brother's arm, "... It's you and me, right? Us against the world. No secrets. You know you can tell me anything!"

 

"Yeah, you're right! Well..." After a sniff, Mingyu looks at his older brother, vulnerable, "My, my girlfriend just left…" Cheol is listening intently.

 

"We were supposed to Netflix and Chill. It was going well till…"

 

"..."

 

"Till?"

 

Silence. 

 

"Gyu, why did she leave?"

 

Frustration takes over Mingyu's face, "Because this blasted thing won't fit!" he crumples the thin rubber and throws it aggressively. 

 

"We planned this out for weeks! Now because of a stupid condom, she won't have Sex with me?!"

 

Cheol clears his throat and clarifies, "W-Wait, let me get this straight: your girlfriend walked out, leaving you sexually frustrated… Cause the condom was TOO small?" 

 

Mingyu blushingly nods. "It's stupid, I know…"

 

Gears ticking. Then something *dings* in Cheol's brain.

 

"Ah!" Cheol exclaims. "I get it now. We are indeed brothers!"

 

Confusion was stapled on Mingyu's face, "Huh?"

 

"I encountered a similar thing during my first few times..." Gyu looked a bit shocked, to which Cheol noted, "Come on, this is the time in our lives when we explore and experiment! So, I took a deep dive into it. I'll tell you more of THAT later, but...

 

(getting back on track, Cheol continues)

 

You must know, Lil bro, that only large condoms like Trojan Magnums would comfortably fit us!"

 

"The big ones?"

 

"Yep! There is nothing to be ashamed of, my guy. Your girlfriend just probably got intimidated and scared of your junk! That's all!"

 

Being the virgin that he was, Mingyu innocently asks, "Scared? Why would she be scared? It's still me."

 

Cheol hums, "You see, not everyone is comfortable or willing to take big dicks! Finding the right people took me a hot minute, but it was worth it!"

 

"Wait…" desperation in his tone, "So, you mean… I'll be a virgin my whole life because I have a big dick?" Gyu sighs and massages his forehead. 

 

"… I, I have no experience; I don't even know how to do it properly! Now, all my chances are out the window because of this?!" an open palm pointing to his concealed junk.

 

"Hey, relax, Lil' bro…" Cheol squeezes Gyu's hefty exposed thigh. "I have a ton of experience. I got you!"

 

In distress, Gyu says, "You should have told me beforehand. I need your knowledge, big bro. Please teach me! I don't want to be a virgin no more."

 

Cheol bobs his eyebrows, "I understand. We will rectify that…" he gives Gyu another firm squeeze.

 

"… But first, show me what you're working with…"

 

~

 

"Okay," Gyu shyly removes the blue pillow. His dick vaults out, slapping onto his abdomen loudly *THWACK!*

 

An audible gasp escapes Cheol's lips, eyes shot open, "Bro! I think a ONE LEGEND condom would fit you best! Dang!" he takes the sizeable meat and jerks it off slowly, marveling at its sheer size and HEAVY weight.

 

Mingyu was EASILY a foot-long! Maybe even longer. But, what's more, striking than that is his crazy GIRTH. Cheol could not even fathom how a human penis could be so THICK! Amazed, his mind lingered—

 

*This thing is GINORMOUS! Perhaps… Perhaps, THIS is what I have been looking for*

 

"I-Is it t-too much, big bro? Will THIS be a problem?" Mingyu worryingly inquires.

 

Cheol zones in on the beads of precum oozing from his brother's wide piss slit, "No… It's perfect. You're perfect!"

 

Even before Gyu could reply, explicit moans were wrung from him. Determined, Cheol sucked his not-so-little brother off! Focusing on pleasuring the prominent glans and frenulum. His hands twisted and kneaded ¾ of the enormous shaft. Mingyu's balls bobbed, along with Cheol's aggressive motions.

 

The bigger guy moaned incessantly. He loved how his brother worshipped his godly member. Mingyu's large hand clutched the back of his hyung's head as it rose above his giant knob, watching the older man's spit SLOWLY drip onto his swollen tip and resume to give him a phenomenal blowjob! "Ah, shit… That feels amazing, bro!" Wads of slobber now cover his vein-stricken junk and giant nuts.

 

While he enjoyed his first proper head, Mingyu couldn't help but observe the high tent forming in his brother's pants.

 

“Hey, hey, ahhh, b-big bro… Why d-don't you let that thing free!" Prodding at the evident dick print.

 

Cheol smirks. "Good idea!" he removes his shirt and shoes and discards his jeans. Mingyu follows suit, taking his top off, biting his lips when the blonde was stark naked…

 

Proving that Cheol was not exaggerating when he said they were both well-endowed. Gyu gapes at the older man's throbbing dick. 

 

Seungcheol was nearly 9 inches long and comparable to a beer can's thickness! While Cheol admits that he's big, his little bro: Gyu is HUGE! Trumping his already impressive member in length, girth, weight, and veins— plus, Gyu's meat was deliciously tan in color.

 

Mingyu's arousal doubles, watching Cheol smuttily sit, his burly legs wide open before him. The blonder jerked and saturated his big dick with its precum. Gyu mimics his big bro's posture, their legs intertwined (scissor-like), sitting sideways on the couch.

 

Then, Cheol presses his sizeable tip to his brother's massive cockhead. The piss slits, kissing, sharing drops, and strings of precum. "Fuck…" Mingyu hisses. "Our big cocks are making me so horny, bro!"

 

Cheol smirks, scoot closer, and grips their dicks together. Mingyu's calloused hand joined him as they jerked off their stacked cocks, sharing more pre-fluids. "Dang lil' bro, look at how much we're leaking… I love feeling your cock against mine! Fuck."

 

*Storm rages in the background* 

 

The moonlight and TV cast shadows, enhancing all their flexing beefy muscles while they pleasured themselves.

 

"I think you're ready, lil' bro…"

 

"Ready?"

 

"Yes. Ready to fuck me!"

 

"God, yes!"

 

Mingyu manhandles Cheol, lifting him to the edge of the couch. Gyu situated the older's upper body on the couch's arm, his head comfortably resting on their festive throw pillow. 

 

Their dicks were doused in so much pre-nut and saliva Cheol reckoned it was more than enough to act as a natural lube. Still, it's best to proceed with caution—

 

He directed the younger to get into position. Mingyu lifted his brother's right leg onto his left shoulder while he snaked an arm around Cheol's left thigh, pulling the older man closer. Their lengths are rubbing. "Is this right, big bro?"

 

"Yes, it's perfect, but wait…" Cheol places a hand on Mingyu's massive sex mounds, rubbing the man's hard nipples. "Go, go slow… Okay? Slow… Slowly… AhhhAhhhAHHHHHH…" his legs shook when Gyu forcibly breached his hole with his cockhead.

 

"Argghhhhhhhhh, shit!"

 

"Big bro? You, okay? You're shaking…"

 

"Ye-Yeah… Yeah… Just, it's… AhhhhhAHHHHH! You, you, have the BIGGEST DICK!" thinking that his partners may be experiencing a similar feeling when he fucks them.

 

Mingyu reddens, "Sorry, hyung, but I barely entered you…" he gently pumps Cheol's length as his cockhead pushes further.

 

Cheol felt a sharp sting; his hole was being stretched to its limits, "I-I know… But you're SO HUGE! You can destroy a grown-ass cow with THAT THING— Arghhhhhhhhhh FUCK, Mingyu!"

 

*SMACK! *

 

Being inexperienced, Mingyu surprised the blonde by driving 2/3 of his length without warning. Cheol felt all the air pushed out of his lungs! His dick dramatically pulsates FIRMER than ever and leaks more dollops of precum!

 

Mingyu was now hovering on top, almost folding his hyung in half, big muscly arm flexed, left hand gripping the couch's arm for leverage, his right arm pulling Cheol's left thigh closer to his body. 

 

"Fuck, hyung… You're so tight, and your dick is SO HARD! Look!"

 

At that moment, Cheol knew, Mingyu had found his hidden P-spot; it was located farther than average. He seemingly needed something LONG and HUGE to reach it— 

 

Body quivering from the erogenous discovery, Cheol clasps Mingyu's muscly forearm, his other hand resting on the younger's stiff pecs.

 

"Unghhh-hhghhhahhhh… God, I can't believe HOW BIG you are, Mingyu! Ahhhhhhh… Jesus, I can feel y-you inside my sto-stomach!" 

 

Always a top, Cheol now learns the pleasures that come from bottoming.

 

"M-Move, p-please… AhhhhAhhhhARGHHHHHH GOD!"

 

*PLAP, PLAP, PLAP, PLAP*

*PLAP, PLAP, PLAP, PLAP*

*PLAP, PLAP, PLAP, PLAP*

 

"YesYesYesYESYESYES! Open up your big bro's pussy!" Seungcheol did his best to keep up with his stepbro's vigorous and dominating drives. "Holy crap! You FUCK like a raging bull, brah!" *their brawny muscles jolt from the barbaric motions* 

 

The blonde feels his hunky lil brother's barrage getting stronger and stronger, delivering mindblowing pleasures to his puffy prostate, "Give me that big fucking dick! Come onnnnnnn, Gyu, wreck my fucking cunt!"

 

*PLAP, PLAP, PLAP, PLAP*

*PLAP, PLAP, PLAP, PLAP*

*PLAP, PLAP, PLAP, PLAP*

 

"Gahhhhhd, I love your tight pussy and PHAT ASS, hyung! Taking me so fucking well, like you're made for my cock!" Cheol's giant globes jiggled like airbags, bearing every robust impact from Mingyu's merciless thrusts! 

 

Each jab is delivered with incredible speed and uncanny strength that only seems to increase with every passing moment.

 

*FASTER skin on skin smacking clangs in the dark room*

 

Cheol now screams in pain and pleasure; it was all too much!

 

He begs Mingyu to slow down. But it all fell on deaf ears since Mingyu was lost in the newfound sensation of his dick. Forfeiting all intent of awareness, the hunky freshman focused on his self-gratification! Hips rocking in and out at an alarming pace as his brother's pussy juice coats his pulsating shaft more and more! 

 

Gyu whips his head back and, with sexy grunts, rams his HUGE cock TWICE as powerful! Cheol appeared like a lifeless fuck toy. He had no choice but to TAKE and TAKE and TAKE and TAKE!

 

*The sensual cacophonies of penetration become violent, mated with Cheol's husky pleas*

 

"Sorry, I'm sorry, I'm sorry, hyung! I-I-I can't st-stop; your TI-TIGHT pus-pussy feels SO A-A-AMAZING! I'm, I'm, I'm gonna… Arghhhhh, FUCK, Hyyyyuuuunggggggggggg!!!"

 

Mingyu sees white, and in a snap, he fills his stepbrother to the brim!

 

Cheol felt every powerful ejaculation smearing his velvet walls. His stepbrother released so much that his belly began to bloat!

 

"Fuck, Gyu! Look, look at it! Yo-You're getting me fucking pregnant, you piece of shit!" Both gaping at how the blonde's lower abdomen inflated. Loaded with his stepbrother's potent swimmers!

 

Being bred made Cheol hornier! He was even surprised to feel THAT way, which pushed his veiny dick to get harder, expelling more pre-spooge onto his puffed belly. He saw how Mingyu shuddered from the intense orgasm, who was now slowing down...

 

After over 20 substantial shots of cum, Gyu perceives his climax is weakening. "Ahhhh, Ahhhh, Ahhhh God, that felt so good!" he yells. The slide was getting ridiculously smooth with all the stockpiled cum in his hyung's distended canal.

 

Almost coming to a halt, Mingyu start feeling overstimulated. It kicked in more when Seungcheol purposely clenched and unclenched his hole. 

 

Being experienced, Cheol catches that Gyu is attempting to come to a standstill. So, he grabs the back of his stepbro's neck, their noses mashed, breathing hotly on each other's faces, and commands:

 

"No! You listen to me! You don't get to stop until you make me cum with that huge cock of yours! Got it?!" firmly clasping the younger's neck, he roars, "Keep fucking me!"

 

"But hyung?! It, it hu-hurts…"

 

"NO, no BUTS! You're going to ride it out and KEEP FUCKING MY DIRTY HOLE! Understand?! KEEP. FUCKING. ME. MINGYU!"

 

With a firm resolve, Mingyu obeys; with his teeth clenched and loud grunts, he fought the cruel & sensitive sensation and restarted fucking into his older brother! 

 

"SHIT, it hurts! Gahhhhhh, hyung, ARGGGGGGHHHHH FUCKKKKK…"

 

*Harsher dick-on-ass pounding ensued, enhanced by pornographic clangors and lewd profanities*

 

Over two sustained minutes of this brutality. Cheol suddenly arches his back, abs gone, his bloated-cum-filled-abdomen stretches. Revealing the IMMENSE cock outline of his stepbrother's horse-cock, attempting to drill out of his skin.

 

"Don't stop, don't fucking STOP, brah! Fuck me, fuck me, fuck me, fuck me, FUCK the living lights out of MEEEEEEEE!!!" sinful shrieks blasted from his throat as Cheol experienced the BEST orgasm of his life!

 

*SPLURT! SPLURT! SPLURT! SPLURT! *

*SPLURT! SPLURT! SPLURT! SPLURT! *

*SPLURT! SPLURT! SPLURT! SPLURT...*

 

Seungcheol unleashed over 30 viscous white ropes of jizz! Creating an absolute mess on his and Mingyu's sweaty torsos. Cum sprayed everywhere! Reaching ON & past his face, across the floor above his head.

 

Every time Gyu's shredded v-line pelvis drives in, the younger's colossal fuck stick pummels at the blonde's battered prostate, causing Cheol to release MORE spunk until he was milked dry! Reaching an INTENSE arid orgasm! 

 

*Unintelligible and carnal vowels rang in their ears as Cheol erupted numerous times*

 

Till Seungcheol's mouth was wide open into a silent cry. That was when he heard Mingyu's manly whimpers and rugged BANGING attack on his pussy! Sounding so titillating, each vowel consumed his mind.

 

*PLAP, PLAP, PLAP, PLAP*

*PLAP, PLAP, PLAP, PLAP*

 

"Jesus Christ! You're STILL SO TIGHT, big bro! This FEELS LIKE HEAVEN! Uhhhhhh, Ahhhhh, hyung, hyung..." Buckets of pre-nut, cum gunk, and slick are gushing out of Cheol's desecrated arsehole.

 

*PLAP, PLAP, PLAP, PLAP*

*PLAP, PLAP, PLAP, PLAP*

 

"... HyungHyungHyungHyungHyung, I FEEL IT, IT'S, IT'S... I… I… I…”

 

*SMACK! SMACK! SMACK! SMACK! *

*SMACK! SMACK! SMACK! SMACK! *

*SMACK! SMACK! SMACK! SMACK! *

 

Cheol whips his eyes at his stallion of a brother. Watching Mingyu's massive damp pecs bounce, sweat dripping off every muscle, stocky abs contracting from the BEASTLY fucking! Then in an instant, Cheol feels Mingyu's already gargantuan rig GROWING—

 

"G-G-God, Min-Mingyu! You're RIPPING m-me in ha-half! Are y-you clo-close? Are y-you going t-to—"

 

*SMACK! SMACK! SMACK! SMACK! *

*SMACK! SMACK! SMACK! SMACK! *

 

"YeahYeahYeahYeahYESSSSSS! I'M GONNA BUST inside you again, big bro! HERE IT COMES! FUCKING TAKE ALL THIS CUM!!! AAAARRRHFFFFHFHGGHDGFHHHHHHHHHHH!!!"

 

Veins about to pop from his neck and body, Mingyu overcame the sensitivity + discomfort and grandly climaxed for the second time!

 

He was unloading nearly as much as his first orgasm! Dense man milk quickly seeped through, borderline spraying out the sides of his shaft as it continued to bulldoze in and out, in and out, in and out of his stepbrother's massacred man-pussy! The poor couch was soiled with pools and puddles of cum. It was a SPLATFEST!

 

*gears churning*

 

It dawns on Seungcheol that his no-longer-virgin-brother WILL (without a doubt) BE famous in their school! Not just because of his stunning looks, Herculean physique, and authentic, likable personality— but also for his sensational fucking skills and monstrous cock!

 

*Mingyu's advances decelerate after a minute, and the lovemaking sounds subside*

 

Hunched, their foreheads pressed at one another, and Gyu's sweat drips onto Cheol's face. Both were catching their breaths now; Mingyu inhaled deeply and cautiously pulled out. *A slosh, suction, and lewd pop* Unsheathing fully. Thick strings of jizz and cum froth connect Mingyu's cock and the blonde's FAT ass as he retreats… Leaving Cheol's hole extremely open, empty, and gaping. MORE virile semen floods out, creating a bigger mess on the couch.

 

 

The TV was still on, and the thunderstorm outside raged.

 

Mingyu sits back down on his side of the couch.

 

The dorm room reeks of Sex.

 

Cheol catches Mingyu shaking (post-orgasm), panting, and trying his best to recover. His eyes journey down, all over the younger's remarkable bulky muscles, all their shared semen on sweaty tanned skin. Every part of Mingyu appears like it was sculpted by the Gods; just then, his gaze comes to a gridlock— eyes fixed on his stepbrother's king-sized cock, STILL FULLY fuckin' ERECT!

 

Astonished was an understatement. 

 

They stare at each other when Gyu sensually questions, "B-Bro? Wh-Why am I st-still ROCK HA-HARD?!" His oversized cock thrums continually.

 

Lust consumes Cheol's face, licks his lips, and fists his cum soaked dick till he is STIFF as a brick (in mere seconds). "Th-that's a g-good thing! Let's not put that to waste, lil' bro…" 

 

Mingyu keenly ogles at how his stepbro's big dick hardens back up! Causing his impressive meat to drip fresh batches of cock snot.

 

Cheol leans forward in a sitting position, head leveled with Mingyu, lips mashing, and says: "… How about I teach you how to cum hands-free? Would you like that?"

 

Gyu maliciously smiles; Cheol seizes his jaw and sloppily makes out with his brother while leaning back. A lot of tongue and spit. The brothers tenaciously rubbed their BIG dicks together when Cheol gradually stuffed his jizz-soaked fingers inside his baby brother's virgin hole, prepping the younger hunk for what was about to come.

 

"Ahhhhhh… I love the feeling of your fingers in my ass..." Mingyu admittedly moans upon insertion into their feverish make-out and states, "Sex with you is the best, hyung... Wait, d-does this mean I'm bisexual?"

 

Cheol smiles, brushing off his stepbrother's identity crisis sitch, "We'll talk about that after this round, okay baby? ... For now, just focus..." his calloused hands opening up his hunky brother's ass cheeks, "... And let me fuck this virgin pussy!" he proceeds to stick his large rig inch by inch.

 

Mingyu's loud whimpers pierced the dorm walls; the sound of hard rainfall could not conceal their incestual rackets.
