—

In the early morning before the sun had even come out, Lu Hao got out of bed. He tried to be quiet about it, but as he pulled on his jogging clothes, Hong Sheng stirred.

"Mm... you're going today?"

"Yeah. The city leaders called me over. I'll have to head there later in the morning." Now that the F City region was mostly peaceful, the talks with government officials were all politics. Lu Hao went to bed to give Hong Sheng a kiss. He chuckled at the sleepy look on Hong Sheng's face. "Going to get some exercise in first. I'll be back soon."

"Don't jog." Hong Sheng stopped him. "I'm still... from last night..."

The implication of what they'd done made a shudder of anticipation raced down Lu Hao's back.

It was rare for Hong Sheng to be so proactive. Lu Hao stripped and sank back down into bed, his lips widening into a sultry smile.

"Well... If you insist."

Hong Sheng was still tired and sleepy. With an incoherent murmur, he stretched out a long leg and hooked it around Lu Hao's waist. Lu Hao chuckled and mouthed at Hong Sheng's chest while he used a hand to stroke Hong Sheng to hardness. The other felt Hong Sheng's hole, checking his condition. He'd cleaned Hong Sheng down there after they'd had sex last night, and the hole was still soft and pliant. It should be fine to enter after some quick prep.

Grabbing the lube from the bedside table, Lu Hao was ready to stretch Hong Sheng out again and get him slick. But Hong Sheng's brows furrowed when he heard the click of the cap opening.

"Don't need it."

Confused, Lu Hao paused in squirting the lube in his hand. He coaxed, "Hong Sheng, I need to prep you first. I'll warm it up and make it comfortable, alright?" He thought that Hong Sheng was complaining about the texture and temperature of the lube. Lu Hao usually did a good job of warming it before he used it on Hong Sheng, but they'd been a little hurried last night.

"No. I don't need it. Just..." Hong Sheng was being strangely stubborn. Suddenly, he got up and pushed Lu Hao to sit on the bed. Lu Hao bounced a few times as Hong Sheng climbed on top of him. He groaned when Hong Sheng reached between their bodies and pumped Lu Hao's cock a few times to get him hard. There was a lazy, erotic motion to it, like he didn't need to put in effort—and he didn't, because the moment Hong Sheng murmured, "Get hard for me," Lu Hao's dick throbbed and stiffened in his grasp.

"Hong Sheng—" Lu Hao tried his best to gently wrassle the half-asleep but determined Hong Sheng. "Hang on, I'll get you slick," he said, moving his clumsily-lubed up fingers to Hong Sheng's back.

But Hong Sheng wasn't willing to wait. One moment, he was still kneeling on top of Lu Hao, and the next, his legs completely gave out, and Hong Sheng sank straight down on hard cock.

"Fuck!" Lu Hao exploded. It felt so damn good—but it was also dangerous as hell. Hong Sheng let out a long, throaty moan, and Lu Hao wasn't sure if it was out of pain. His hands gripped Hong Sheng's thighs tightly, ready to lift him up. "Fuck, Hong Sheng, are you okay?"

He didn't get an answer. Instead, he just heard Hong Sheng heave a contented, pleased sigh as he wrapped his arms around Lu Hao's neck. His legs crossed behind Lu Hao's back in a demanding and tight lock, like he couldn't bear for Lu Hao's cock to leave him for a second. He was so sweet, so utterly reliant as he leaned on Lu Hao—but the constant squeeze of his insides and the slow slide of his wet hole reminded Lu Hao that this was very much not an affectionate Hong Sheng asking for a hug.

Clearly Hong Sheng was much more out of it than he'd realized. Lu Hao's fingers pressed against the tight rim of Hong Sheng's asshole around his cock, probing it hurriedly, checking for any wounds or tears. He didn't see any blood, but—fuck, Hong Sheng was so wet and slick inside.

Lu Hao almost wondered if he hadn't actually remembered to clean Hong Sheng out. Was his cum from last night still inside him? Was that why Hong Sheng had no problems sitting on his dick?

Hong Sheng's nails scratched at Lu Hao's back. "Move?" It was a plaintive little word, a little beg for affection. Lu Hao couldn't deny him.

His breath was shaky as Lu Hao replied, "Okay, baby. Tell me if it's too much."

Lu Hao bounced Hong Sheng on his lap, the short, shallow thrusts piercing Hong Sheng's abused asshole. Just last night that tight little furl had stretched wide open for Lu Hao to fuck into redness, and it wasn't more than a few hours later before that sore and loose hole had to open up for him again.

And it swallowed Lu Hao greedily, with such a possessive grasp on his cock that it didn't want to let go when he pulled out. Hong Sheng keened on a thrust that had Lu Hao sliding out of him halfway. His hands scrabbled against Lu Hao's back, and he hugged him tight, like he was begging Lu Hao not to leave.

How could Lu Hao bear to? Of course he had to feed his cock back inside Hong Sheng, snapping his hips forward with a particularly deep and strong thrust.

"You like it, baby? You like being full and warm?" He kissed Hong Sheng's ear.

Hong Sheng groaned, burying his head in the crook of Lu Hao's neck. Dirty talk easily made him shy. Lu Hao rubbed his back, comforting, and brought a hand to Hong Sheng's dick. He played with it, jacking Hong Sheng off with ease to match the bouncing of his hips.

It wasn't long before Hong Sheng was cumming all over him, white spurts coating Lu Hao's abs. His hole squeezed tight around Lu Hao's dick with each trail of cum that shot out. Hong Sheng moaned and rubbed his cheek on Lu Hao's neck, the satisfaction in his voice making Lu Hao's hips stutter. Kissing the side of Hong Sheng's head, Lu Hao groaned and murmured, "I'll finish soon, baby. You're so good."

After a few more hard thrusts, his dick throbbed and released his load deep inside of Hong Sheng. He loved doing this. Hong Sheng didn't really care for it, usually just going along with the ride to make Lu Hao happy. And for Lu Hao, Seeing his cum drooling out of Hong Sheng's hole did something to him.

He always cleaned it up, after. Usually while Hong Sheng had fallen asleep from exhaustion. Leaving the cum inside could easily irritate the intestines, and—well, it wasn't pretty. The first time he'd left it in, Hong Sheng's stomach upset the day after had taught Lu Hao to be extremely thorough in his cleaning.

But now Hong Sheng was full of his cum again, and the two panted, sated in the afterglow. Lu Hao kissed the side of Hong Sheng's face, and kissed his lips when Hong Sheng turned toward him.

"Thank you, baby. You wanna sleep while I get us cleaned up?"

He didn't expect for Hong Sheng to bite his lips and give him a sloppy kiss. "Again," Hong Sheng pleaded, panting, with a roll of his hips.

Lu Hao's breath stuttered, and his dick filled out thickly.

He readjusted Hong Sheng's position on his lap, and kissed him slow and deep.

"Okay."

By the time Lu Hao had to go, the bedroom was all in a mess. He had tried to bring Hong Sheng with him to take a bath, but Hong Sheng grumbled at him and clung to the bed. "I'll handle it," he mumbled, smacking away Lu Hao's hands when he tried to inspect Hong Sheng's ass and help clean things up.

"Okay, if you're sure," Lu Hao said, patting Hong Sheng's butt. "Don't fall asleep. Remember to get it all out."

Hong Sheng just glared balefully at him, and Lu Hao hurried away to get to his city meeting.

In the post-apocalypse, while the world was in reconstruction, F City had become one of the major urban hubs of the country. Today, representatives of important government officials and organizations had gathered here and requested to meet Lu Hao.

He showed up just in time. Walking into the meeting room, Lu Hao saw a good number of professorial types along with the usual bureaucratic suits. That didn't usually bode well for these meetings. The last time, some researchers tried to pressure Lu Hao into letting them clone him.

Once the meeting started, Lu Hao knew he was right to be wary.

"If humanity is going to survive, we need a strong population," one of the representatives started.

"It's for the good of the world..."

"The future depends on..."

"A powerful ability user such as yourself needs to..."

"We have a list of partners for you to choose from. All of these women have consented, so if one—or several—of them catch your eye..."

Just as a man started sliding a portfolio of women's profiles over to him, Lu Hao stood up and walked out of the room.

"Mr Lu!"

"I'm not interested." Lu Hao's tone was glacial. The rising static electricity in the air silenced everyone in the conference room behind him. "I won't share my DNA, and I'm not having a child with any of your 'pre-approved volunteers'. If you really want me to have children, then..."

He thought of something funny, and quirked the side of his lips.

Knowing how impossible this would be, Lu Hao coldly joked, "You'd better find a way for me to get a man pregnant."

While Lu Hao drove his way back, Lisa Xi started blowing up his phone.

"Lu Hao!" she screeched, the minute he picked up. "I can't fucking believe you! What the hell have you done to him?!"

"What?"

Hearing the utter confusion in Lu Hao's voice, Lisa Xi explained, twenty decibels louder than necessary, "Hong Sheng has mutated! How much fucking bodily fluid were you pumping into him!"

Lu Hao nearly dropped his phone.

"...I told you that the virus in ability users and zombies was the same! That you need to use condoms or something might happen! But no, you just had to—you're so goddamn lucky that I was the one to go looking for Hong Sheng and not someone else. Do you even know what he looked like when I found him? What if Yu Qiu was the one busting into your bedroom and seeing all that—"

"Okay, Lisa! How is Hong Sheng right now? What's wrong with him? I'm on my way back, I'll be there in fifteen—is he okay?"

"What's wrong with him? What's WRONG with him?" Lisa Xi's voice went shriekingly high pitched. "God, you absolute—"

And then, in the background, Lu Hao heard a muffled sound of ragged breathing, and Hong Sheng moaned. It was plaintive, weak and in pain, "Lu Hao?"

Lisa Xi let out a 'fuck!' as Lu Hao's anxiety ratcheted up to new levels. He spoke quickly and desperately, "Is Hong Sheng hurt? Lisa, let me talk to him, let him know I'm almost—"

The dial tone sounded. Lisa Xi had hung up on him.

Cursing, Lu Hao tried to call her again, but she never picked up.

Lu Hao sped all the way back to the SG base.

What had happened to Hong Sheng? Had he turned into a zombie?

But they had the healing spring water, and the virus cure. It couldn't be... and yet, Hong Sheng had sounded like he was in so much pain.

The rims of Lu Hao's eyes turned red. He fought back the emotions brewing inside him. He knew he had to focus on just getting there as soon as possible, and yet, he couldn't stop the thoughts in the back of his mind. It was all his fault. Hong Sheng was suffering, changing, because of him.

So when Lu Hao burst through the door of his bedroom, eyes red with self-blame, expecting to see Hong Sheng pale and stiff as he turned into a zombie—

He heard Lisa Xi say, "Oh, thank God," and rush past him out the door while Lu Hao stared at the flushed and feverish-looking Hong Sheng, who was on the bed, wrapped up in blankets like a stuffed dumpling.

"Hong Sheng, are you okay?" Although the situation was a little different from what Lu Hao had expected, he didn't let down his guard. He rushed to Hong Sheng and put a hand to his forehead, which was burning up. "Damn it. Why didn't Lisa get you ice? Here, I'll get you free, let me just... Lisa! Where are you! What's wrong with Hong Sheng?" Lu Hao shouted at the door while he freed Hong Sheng from his blanket ball prison.

Lisa Xi was on the other side of the rapidly-closing door. "He's in heat," she said, acidic. The door snapped shut.

?

Lu Hao's face had a question mark written on it.

While those three words churned around in his head, he didn't see that Hong Sheng stretched out his arms around Lu Hao's body.

By the time Lu Hao finally registered, 'Wait, she just said, 'in heat'?', Hong Sheng had glued himself entirely against the front of Lu Hao's body, and was panting wildly.

"Lu Hao." Hong Sheng's face was flushed, eyes wet and angry. "Lu Hao. Why were you gone for so long?" He sounded like he was going to cry.

A new wave of guilt rolled over Lu Hao. "I'm sorry, baby," he started to apologize, only for Hong Sheng to kiss him. It was a sloppy, sticky, wet kiss, the kind Hong Sheng only gave when he was out of his mind with pleasure and close to orgasm.

When they separated, a long trail of saliva falling from their lips, Hong Sheng said, "I want sex."

"Ah," Lu Hao said.

"You didn't give me enough semen," Hong Sheng was suddenly accusatory, indignant, as he spoke like a little man-eating succubus, "You have to come in me until I'm full. You can't let any drip out or you have to do it again, and you can't—you can't go and take your penis out of me and leave me empty with all your semen spilling out. I had to put it all back in myself, but it wouldn't stay in me because there was nothing to hold it." And to demonstrate this, Hong Sheng grabbed Lu Hao's hand and slid it past his sopping wet underwear to feel at the furl of Hong Sheng's ass.

It was the slickest, softest, most delectable hole Lu Hao had ever felt. It suckled at his fingers, begging him to sink in deeper, fuck it hard, feel how tight and wet it'd be. And as Lu Hao's fingers slid inside, he felt the cum drooling from Hong Sheng's asshole, slowly leaking out.

Lu Hao's breathing grew ragged, and he couldn't help but pump his fingers in and out of Hong Sheng's hole a few times. Fuck, but it was so tight and wet, and it felt... It didn't feel like an asshole anymore, dry, needing to be coaxed open to fit a cock. This was a hole made to be fucked.

"Is this your mutation?" Strained, with his throat parched, Lu Hao barely found the strength in him to ask. "Lisa Xi said you're—in heat?"

A forceful look from Hong Sheng silenced him.

His eyes were baleful, a dark, dangerous shadow in them, and his mouth pressed tightly together like he was very, deeply disappointed in Lu Hao.

He spoke in terse, short words: "You're still not fucking me?"

A wave of arousal swept through Lu Hao, who suddenly found it hard to swallow. His throat clicked, adam's apple bobbing, as his hands rushed to undo the fly of his pants.

Hong Sheng watched him, dark gaze brewing, waiting for Lu Hao to match up to his expectations.

When Lu Hao's cock finally leapt free, Hong Sheng's gaze instantly locked on it.

"This needs to go inside me." The order was stern, with no room for defiance.

Lu Hao shuddered, his entire body like a live wire. "Yes, yeah, let's—lie down, and I'll..."

He didn't even know what he was saying; his entire mind was just filled with how insanely sexy Hong Sheng was when he ordered Lu Hao around, and all Lu Hao wanted was to show Hong Sheng just how good he could be, how good he could make Hong Sheng feel.

Hong Sheng fell back against the bed. He curled up one leg to slide his underwear off, leaving the soaked rag hanging off his other thigh. The act exposed Hong Sheng completely to Lu Hao's eyes; now he saw just how painfully red and aching Hong Sheng's cock looked, weeping precum like it was on the verge of shooting. His balls were swollen, ready to burst as they sat snug and begging to be played with.

Below that was Hong Sheng's obscene hole, changed by the mutation. It was a mess, all wet with cum and slick, winking open as it spurt out that mix of white and clear fluids like it was begging to be fucked and stirred into a frenzy. And it was begging, Lu Hao realized, when Hong Sheng, as if acting on some kind of instinct, hooked a hand beneath his knee and pulled his leg up, all to make himself more enticing for cock.

He was so hungry for it, but Hong Sheng didn't speak a word, only glaring at Lu Hao with tears in his eyes. For every second Lu Hao wasn't in him, it was a betrayal, a sign of how much Lu Hao didn't want him.

Lu Hao wouldn't let him feel that way for a moment longer.

He fit himself against Hong Sheng and fed his dick inside of him, pushing in slowly at first only to feel how easily he slid in. It wanted to take all of him, and soon, Lu Hao's dick fully sheathed itself in Hong Sheng's heat.

But no matter how good it felt, it wasn't about Lu Hao. Panting, Lu Hao's gaze tracked Hong Sheng's reactions; the ecstasy on Hong Sheng's face when Lu Hao breached him, the way his body relaxed when Lu Hao slid all the way inside.

"This is what you wanted? Does it feel good?" Lu Hao teased, as he pulled out and shoved all the way back in, his hips meeting Hong Sheng's with a loud smack. Hong Sheng groaned, and Lu Hao's eyes glinted. He kept pressing, "If you don't tell me, I might not be able to do it. Tell me what to do, Hong Sheng. Tell me what you want."

The humiliation would have kept Hong Sheng painfully silent in normal times, but now, Hong Sheng just made a wild, desperate noise as he tried to move back and get Lu Hao in him deeper, faster. "You have to mate with me," Hong Sheng pleaded. "I feel it. I'm so empty inside. I need you to fill me up with your semen—fuck me deeper, push your glans as deep as it can go. Once your ejaculate goes inside, you have to, have to breed me," and even though half of what he said sounded straight out of a biology textbook, it still drove Lu Hao wild, his body shuddering under Hong Sheng's commands.

If Hong Sheng wanted deeper, then he'd go deeper. Lu Hao lifted Hong Sheng's leg over his shoulder. He steadied Hong Sheng's thigh with a broad hand, fingers pressing deep against the shivering, tender flesh, while his other hand gripped Hong Sheng's against the pillow.

This posture kept Hong Sheng pinned in place, his body stretched to allow Lu Hao to fuck him hard and deep, unable to move away no matter how the snap of Lu Hao's thrusts jostled his body.

Hong Sheng panted, drooling as Lu Hao's thick cock pumped in and out of him, his prostate relentlessly rubbed and teased. His leg jerked in Lu Hao's grasp, and Hong Sheng's dick spurted out a thick line of cum without even being touched. He groaned, eyes dazed with pleasure, going slack against the bed.

But even then, when Lu Hao started gentling his movements to keep from overstimulating him, Hong Sheng keened, "More, keep going, Lu Hao."

"Fuck, Hong Sheng." Lu Hao squeezed his eyes shut, feeling more and more like he was the one getting overwhelmed. He kept going hard for several more minutes, the headboard of the bed slamming against the wall. Finally, he came, pushing in deep all the way, just as Hong Sheng had asked. His dick pulsed as it shot out rope after rope inside of Hong Sheng, who moaned, writhing in Lu Hao's grip.

Both of them heaved with exertion. Lu Hao let Hong Sheng's leg go and bent over to kiss Hong Sheng, passionate and sweet. Hong Sheng softly moaned, and with a tired ease, looped his arms around Lu Hao's neck in a hug. They made out sweetly for a while, the sticky sounds of their mouths mixing with their panting and breathing.

When they separated, Lu Hao smiled and rubbed Hong Sheng's stomach. "Feeling good? All filled up?"

He was just saying that to lighten the mood in the afterglow. He didn't expect Hong Sheng to look him dead in the eye and say, "No."

Lu Hao was dumbstruck.

Hong Sheng's gaze was still feverish. With Lu Hao's cock still in him, he moved his hips up and down again, and he said, "I mean—it felt good. Lu Hao, fuck me again? I'm not full yet."

And that—made something in Lu Hao's brain snap.

He slid out despite Hong Sheng's cry, grabbed both of Hong Sheng's legs, and pushed them up so that Hong Sheng was folded up in a mating press. Lu Hao then slapped his dark, heavy cock over Hong Sheng's gaping and freshly-fucked hole, and smiled sweetly at Hong Sheng.

"Of course. I'll do whatever you like, Hong Sheng. Is this what you like? My cock going in you? Getting bred with my cum? How many times do you want me to cum in you? Three? Four?"

His dick sank straight into Hong Sheng, who couldn't resist as Lu Hao started pounding him into the bed. "Yes, yes, yes," Hong Sheng panted, his eyes going unfocused as he lost himself to pleasure.

Lu Hao ended up fucking him in six different positions, and by the end of it, Hong Sheng couldn't complain about not being full anymore.

It was as Lu Hao was gently rubbing Hong Sheng's stuffed and swollen abdomen that Hong Sheng looked at him and asked, "What was the city meeting about?"

Hong Sheng was more lucid now. It seemed that whatever instinct had driven him wild had been sated. "They're thinking of repopulation. And... they wanted me to have kids."

Hong Sheng gazed at him with a very hard to read expression.

Thinking that Hong Sheng might misunderstand and go into one of those spirals of self-doubt that he was prone to, Lu Hao hurried to explain, "Don't worry. I didn't agree. I told them that the only way they'd be seeing kids from me would be if they found a way for one of us to get pregnant." He smiled earnestly and poked Hong Sheng's cheek. "After all, I'd only ever start a family with you."

The dark, incomprehensible gaze of Hong Sheng continued to hold deeply on Lu Hao. "Oh," Hong Sheng said, with meaning, and there was something wry in his voice when he said, "That's good, then."

A few months later, Lisa Xi, Hong Sheng, and Lu Hao stared in silence at the ultrasound screen.

"Everything about you two is unscientific," Lisa Xi said. She stared at the happy and healthy little beans displayed on the monitor, which were growing in a medically impossible location. "I hate you."
