Chapter Five

Mai & Seo-jun

Six Months Before the Outbreak

Mai knew the risks. If someone had walked into her bedroom then, she'd have had a hard time explaining why she was wearing her brother's underwear.

Correction,step-brother's underwear. Seo-jung was clear on that point.

But it made her feel closer to him. They'd still had his scent when she found them in the laundry basket. The heat from his body lingered in the cotton. In some way, a way that she so desperately wanted, it was like he was holding her.

And it made her feel sexy.

She was smaller than him, but not where it counted. Her butt barely squeezed into the trunks and effect was to stretch the thin, white fabric so tightly over her labia that she could clearly see her puffy lips, each individual fold, even the little button that stood proudly at the tip, begging to be touched.

"Mai, breakfast is ready!"

"Be down in a minute, Mom!"

Mai knew she should stop. But her self-restraint crumbled when her fingers brushed over the outline of that stiff nub.

Simultaneously, she imagined she was touching Seo-jun through his underwear and that he was touching her. The two fantasies blurred into one and the fabric beneath her fingers quickly dampened.

She watched herself in the mirror on her wall, naked save for her step-brother's tight white trunks, her pale skin covered in goosebumps, her perky B cups jiggling as her body shuddered towards its climax.

Her fingers slipped lower, pressing the wet cotton between her folds, driving it inside herself as she fantasied about the penis that had so recently been contained in those trunks.

How much better would it feel to have the real thing? Would it hurt? He'd be her first, her only. He'd be slow, considerate. He'd make it feel good. He'd make her his.

The fluid pouring from her saturated the material, soaking through to her fingers, helping them glide from her clit to her opening, making her gasp breathlessly.

"Seo-jun...Seo-jun..."

And as though her mewling had summoned him, right at the peak of her ecstasy, her bedroom door opened.

"Mai, breakfast is ready and..."

She locked eyes with his reflection in the mirror. She was too far gone to stop. She'd known the risks.

"Seo-jun..." she gasped again, before her trembling knees gave way beneath her. She clamped her hand to her sex, feeling it clenching powerfully beneath her fingers as her tongue lolled out of her mouth and her eyes crossed. "Seo-jun...I'm sorry..."

His expression was inscrutable. He stood statuesque in the doorway, gaze fixed on his gooning step-sister as she came in his underwear.

When it was over, she collapsed onto all fours in front of the mirror and stared shamefully through her fringe at their reflections. She wished he would speak.

"Seo-jun...I..."

Before she could explain, he turned and walked out of her bedroom, speaking emotionlessly as he left.

"Breakfast is ready."

Outbreak Day One

"...I'm boring you, aren't I?"

Mai shook the memory of that day from her mind and brought her attention back to her friend.Friend. That was something new.

"Sorry, daydreaming again. Head in the clouds, y'know."

"Dreaming of anything nice?" Mary asked, sniffling into the sleeve of her shapeless dress.

Mai didn't blush easily but she felt heat rising in her cheeks as she glanced down the carriage to where her step-brother, Seo-jun, was huddled with the rest of his rugby team.

"Oh, uh, this and that, nothing much."

Mary's features softened into a sympathetic smile as she caught the direction of Mai's gaze. The red-head reached out and squeezed Mai's thigh.

"I get it. I know what it's like to feel unwanted, like nothing you do is ever good enough. Father..." Mary's lip wobbled and tears welled in her eyes again. "...Father was...Father was a godly man. He was just and stern and devout. And now...now I'm alone."

Mai placed her hand atop Mary's and held it tightly as the tears began to fall down her dimpled cheeks. "You're not alone. You've got me. And I've got you. We're friends."

Mary couldn't help smile at the bright innocence of the tiny teen.

"Friends," she agreed, before looking pointedly down the aisle towards Seo-jun. "And friends don't let each other do things they'll regret. You should talk to him. He's your brother."

"Step -brother," Mai sulked.

"Brother, step-brother, what's the difference? He's family."

"He abandoned me."

"You should give him a chance to explain."

Outside, the English countryside rolled by, unaware of the doom soon to spread across the land. Mary was right - there might not be another chance.

"Seo-jun. Can we talk?"

Seo-jun followed Mai's gaze to the group of rugby players huddled around him.

"Alone?"

Even with the mortal danger they were in, Mai noticed how her step-brother's teammates still leered at her body. There was even a few condescending titters as Seo-jun detached himself from the group to follow her further down the carriage, with his tail firmly between his legs.

Mai dropped into an aisle seat and Seo-jun took the one opposite. A few rows away, Mai could hear low murmuring where Ellie and her father were reuniting.

"...I've been a monster..."

"...I'll get you to your mom..."

She turned her attention back to Seo-jun and caught his eyes lingering on her slender legs. She self-consciously tugged at the tiny skirt as he glanced away shamefacedly.

"Mai, listen, about what happened earlier...Iwantedto let you in, I swear, but we didn't know you weren't, well, y'know..."

"Horny?"

Seo-jun's eyes flitted to her legs again, then quickly away. "Uh, I was going to say infected, but, yeah, I guess."

"It's okay. I get it."

"You do?" Seo-jun asked, hopefully.

"That's not what I wanted to talk to you about."

"Oh. I assumed, y'know, after what happened, that you were pissed with me and..." Seo-jun trailed off as he became aware of Mai's unblinking stare. "Whatdidyou want to talk to me about?"

"Who knows what's waiting for us at the other end of this line. We might not have long left. And before anything happens to us, I need to know."

At that moment, Mai felt her peculiar sense tingling. She took a deep breath, willing away the shimmer at the edge of her vision, repressing the intuition stirring in the pit of her stomach.

"...Mai? Earth to Mai. What do you need to know?"

She didn't know how long she'd been in her trance. Fighting the nagging itch at the edge of her awareness, she turned back to her step-brother.

"I need to know if you wanted me to find them."

"Find...find what?" Seo-jun asked, colour rising in his cheeks.

"Your underwear, Seo-jun. I need to know if you left them on purpose. I need to know if you left them out for me."

Three Months Before the Outbreak

They'd barely spoken in weeks. What can you say to your step-brother when he finds you masturbating in his underwear?

Luckily for Mai, she was used to being alone. She liked solitude. That's what she told herself, at least.

Things went back to the way they'd always been. Seo-jun kept himself busy with parties, sports, and girls. Mai kept out of his way and out of the laundry basket.

Which worked just fine, until she found the freshly worn pair of mens underwear discarded on the bathroom floor.

Mai knew the risks. It was probably a trap. But she'd missed him. And try as she might, she couldn't ignore those thoughts she had about him when her overactive imagination drifted off during class or when she lay in bed alone at night.

Her clothes were on the bathroom floor before she knew what she was doing. She picked up the grey trunks and was surprised by their weight.

Something dripped out of one of the leg holes and landed on her foot - a milky, sticky fluid that slowly ran down the contour of her foot and pooled between her toes.

The scent of it hit her when she peered inside - musky and masculine, like before, but so much more potent. The source of the smell was plastered to the front of the trunks. Streaks of thick, creamy goo oozing through the fabric.

Mai whistled appreciatively. "Bats and biscuits, bro. Way to fill up on zinc."

Even as part of her mind thought to deposit the soiled underwear in the laundry basket, another, more powerful voice argued for a different course of action.

She'd felt close to her Seo-jun when she wore his underwear before. How much closer would she feel to him with his seed sandwiched against her?

She had to know.

"I'm sorry, Seo-jun," she whispered, as her trembling hands pulled her step-brother's underwear up her slender legs.

She paused with his underwear most of the way up her thighs, holding the gooey front of the trunks away from her body, and looked down at the mess they contained. The entire universe seemed to narrow to the pool of brother-cream beneath her pussy.

She could feel her own excitement dripping from her, watched it land in that glistening reservoir, unconsciously licking her lips as their juices combined.

Her and him, Seo-jun and Mai, brother and sister, together, as one. It was all she'd ever wanted.

"Oh god, Seo-jun, I'm sorry."

Mai started cumming the instant she felt her brother's semen on her skin, spreading between her legs. She pulled his underwear higher, stretching the syrupy fabric tighter to her lips, forcing his slick deposit between her folds and into the deep valley of her magnificent ass.

Her brother's essence was on her, moulding to her body like a second skin, flowing around her clit like liquid satin.

But it wasn't enough. She needed more.

Lost in the reckless abandon of her climax, Mai drove two fingers against the damp cotton, forcing it - and the smear of sweet honey on it - inside her spasming hole.

They were one, brother and sister, together.

It was all she'd ever wanted.

Outbreak Day One

"You...you found them?"

"They would have been difficult to miss, Seo-jun. You left them in the middle of the bathroom."

Seo-jun withered under Mai's unreadable stare and dropped his head into his hands. "I don't know what I was thinking."

Mai placed a comforting hand on her step-brother's knee, ignoring the way he flinched at her touch. "So youdidwant me to find them?"

"I... shit, Mai, I'm sorry. Let's just pretend it never happened."

"But I don't want to pretend. I liked it. It was nice."

Seo-jun peered through his fingers. Mai smiled innocently at him. "You liked it?"

"Uhuh. It felt squishy."

"Felt squishy? Shit, Mai, did youwearthem?"

"Isn't that what you wanted?"

Seo-jun had to think about that one. "I never really thought...I don't know what I wanted."

"Well I did. I mean, I do. I want someone to look out for me, to protect me. I want to feel safe, to feel cared for. I want to feel wanted, for someone to want me the way I want them. Toneedme like I need them..."

Mai felt queasy with the effort of repressing her sixth-sense. Every cell in her body was screaming at her but she needed to finish what she started. She needed Seo-jun to hear.

"...like I need you, Seo-jun."

"Mai, this is wrong, you can't feel this way about me."

"You probably should have thought about that before you planted your jizzy underwear for me to find."

Seo-jun buried his head in hands again. "This is so fucked up."

"Why?"

"Why?" Seo-jun exclaimed, "Get your head out of the clouds, Mai! Our parents are married. We're..."

"Siblings?"

"Related," Seo-jun corrected.

"Just say, say it once. Say it while you still have a chance."

"It's fucked up because...because...because I'm your brother."

Mai's heart swelled and, for a few blissful seconds, her nagging intuition abated. "I don't care. Because I want you, Seo-jun. I want my brother."

It was out there. But before Seo-jun could reply, they heard a breathy gasp nearby.

"Oh god...Daddy...I want...please...I want..."

At the same time, a dam broke in Mai's mind. The force she'd been holding back overcame her willpower. In that moment, she knew.

But Seo-jun was already standing, glad for the excuse to extract himself from his step-sister's uncomfortable revelation, walking slowly towards the source of the erotic moans. He could see the girl he'd rescued from the platform, her blonde head moving up and down above the seats.

"I want...oh fuck Daddy, I want..."

He knew he should stop. He knew the risks. But a morbid fascination drew him on.

He had to know if the cute teen reallywasdoing what he thought she was. Because if it really was her daddy, then maybe what Mai had done wouldn't be so bad. She was only his step-sister, after all. He had to know.

"I want...I want to feel it, to feel you, oh fuck...I want you to cum with me, in me, oh fuck, I want it, I want...I want...I want!"

Seo-jun was only one row away when the blonde threw her head back and screamed the final two words. Her back was arched, her body taut like a drum, her chest thrust forward, thick nipples straining at the stretched crop top.

At that moment, as she hung on the precipice, she locked eyes with Seo-jun. He remembered the way Mai had locked eyes with him as she orgasmed in his underwear. He'd wanted so badly to yank his underwear over that mesmerising ass of hers and thrust his raging hard-on into her spasming cunt.

He'd wanted her that day and every day since. That's why he'd left out another pair, in the vain hope of catching her in the act again, even though he knew it was wrong.

"Fuck, sweetie, I'm cumming! Daddy's cumming inside you!"

The man's groan broke the spell. Seo-jun snapped back to the present as the man's orgasm precipitated his daughter's. Her body snapped forward like a bullwhip, vibrating uncontrollably as she clung to her father's shoulders, all the while gasping, "I want...I want..." until she finally rested still atop him, panting wordlessly.

But the same two words continued to be spoken from across the aisle of the spent pair.

"I want...I want..."

A figure rose, stumbling into the aisle, with his trousers around his ankles and his hands wrapped around a hugely swollen cock.

"Coach Dale!" Seo-jun gasped.

The rugby coach turned toward Seo-jun's voice and continued the blonde's refrain in a gravely growl.

"I want...I want..."

Seo-jun stumbled backwards into something soft. He spun and found himself face-to-face with Mai. Her eyes were unfocused, her voice wispy and thin.

"They're here."

Strangely, Seo-jun didn't feel panicked. He was possessed by a cool focus. Time seemed to slow down as he moved with a fluid ease, taking Mai's hand in his and leading her with a fast, measured stride away from his lurching coach.

"Yo, Seo-jun, where you headed?"

Seo-jun ignored his burly teammate, pushing through the huddle of broad shouldered boys, and continuing quickly towards the far end of the carriage from the lumbering lecher.

A few moments later, the first of the rugby team saw the change that had transformed their coach. Seo-jun ignored their dismayed yells, forging on past the young woman with the blaze of red hair, who called out to his dazed step-sister. "Mai, where are you going? What's wrong?"

Mary's voice cut through the fog clouding Mai's mind. She tugged weakly at Seo-jun's hand. "Seo-jun, wait."

"There's no time, c'mon."

"No, wait. She's my friend."

"You don't have any--" Seo-jun caught himself just in time. Glancing past his step-sister and the confused redhead, he saw a confusion of bodies as his teammates wrestled into the aisle to escape the oncoming lecher. "Okay. Come with us. Quickly."

"C'mon Mary," Mai sighed, slipping back into her trance-like state. "They're in the carriage. We have to go now."

The wide-eyed redhead scrambled to her feet and hurried after Seo-jun and Mai. "They'rehere? How? Oh, Lord, help us. We're damned!"

"It's fine," Seo-jun said, straining to keep his voice level as he hurried towards the door at the end of the carriage, "no one is damned. We'll simply go into the next carriage and lock Coach Dale in..."

Seo-jun fell silent. They'd reached the end of the carriage. And they had a problem.

"What's wrong?" Mary asked, "Why isn't the door opening?"

"Because we're at the end of the train," Mai said dreamily. "There's nowhere else to go. We're trapped."

Beside the door was a keycard reader. A sign above it read - 'driver's compartment, staff only.'

Seo-jun pulled at the handle, throwing his weight behind it. The door budged an inch on its runners then hit a barrier and snapped back.

"Fuck. We need a keycard."

"The conductor has a keycard," Mai offered helpfully.

"Thank Heavens!" Mary exclaimed, before adding with a degree of concern, "whereisthe conductor?"

"Getting fellated in carriage C," Mai answered blankly.

Seo-jun wrenched the door again. His shoulder jarred painfully as it caught on the invisible barrier but he sensed the obstruction slightly weaken. He threw his full force against the door, driving into it again and again. "I can...do it...just need...a little...time!"

"I think we're out of time," Mai said.

"Lord above!" Mary gasped.

Seo-jun risked a quick look back down the carriage. It took a moment for his brain to comprehend what his eyes were seeing. The infection had spread like wildfire, overrunning his teammates with a insatiable urge to suck and fuck.

The pack of stocky athletes were engaged in a wholly different type of contest to what they were used to - a violent race to tear each others clothes off in a heat of passion.

Seo-jun watched, dumbfounded, as one of this closest friends, a hulking giant, dropped to his knees, lay his chest flat on the train floor, and reached back to spread his colossal cheeks. Another of his teammates accepted the invitation, burying his face in the wide valley of his ass and chomping down enthusiastically.

"Oh gosh," Mary whispered, following Seo-jun's gaze, as another towering rugby player lumbered past the human-centipede of rimming rugby lads, his gaze fixed on the three of them.

"I...want..." croaked the rugby player, pawing at the huge tent in his short-shorts. "I...want!"

A primal urge of protectiveness burned inside Seo-jun. He stepped between his infected teammate and the girls, pushing them back against the locked door to the driver's compartment.

Seo-jun raised his hands towards his teammate. "Mike? Mike, if you can hear me, you need to stop."

The thing that had once been Mike shambled onward. "I want!"

"This isn't you, Mike. You don't want, trust me. You've got a girlfriend, Sally, remember? Remember Sally. Remember Sally for me, Mike."

"I want!"

Seo-jun curled his hands into fists and widened his stance. "Don't do this, Mike. Stop there, not another step."

But as zombie-Mike staggered closer, a strange drowsiness settled on Seo-jun. His arms felt heavy and began to sag. Despite the danger, a sense of serenity began to take hold of him. He felt like he was sinking into a warm bath, like the first beer after a hard day at work, like entering a hot, moist cunt after a long build up.

"...Seo-jun. Seo-jun, watch out!"

Mai's voice cut through the serotonin overload, just in time. Zombie-Mike lunged for Seo-jun, who ducked, then exploded forward, driving his shoulder into his friend's solid trunk and hefting his mass upwards and backwards.

It was a textbook tackle and zombie-Mike flew back down the aisle. He landed in a heap atop the human centipede behind him. Seo-jun regained his footing and shook the effects of the intoxicating aroma from his head as he readied himself for the next assault of aroused animals.
