When Yueyue got back to the gym, Xiaoyun was still running on the treadmill.
"Wow, that is very impressive. When did you run that fast?"
Yueyue looked at the distance that Xiaoyun ran, and it was way more than she could have ever done in less than an hour.
"I don't know either. There was no way I could run like this a few days ago," Xiaoyun replied as he slowly decreased his speed and eventually stopped.
"Maybe something to do with your power."
After Yueyue responded, she suddenly smelled a strong odor coming from Xiaoyun.
"Um, you probably should go take a shower... And I'll set up the equipment in the meantime."
Xiaoyun sniffed himself at the shoulder. Then the smell hit him just as strong as Yueyue. So he left the gym and ran upstairs to the restroom.
---
"Hm, that wasn't just sweat smell... Why does it smell like that white liquid in the restroom? What are Yuqi and Xiaoyun hiding?"
Yueyue tried to come up with possible ideas as she pulled the yoga mats from the shelf and laid them on the floor.
But she couldn't think of a connection, so she took out her phone and called Ningjing in the meantime waiting for Xiaoyun.
"Hello?"
"This is Ningjing, who are you?"
"I'm Yueyue. Jingjing, how are you doing? We haven't talked for so long."
"Yeah, it has been a while... It's going okay for now. Mingxu and I are in an air-raid shelter together. How is Miss Leyan?"
"Mom is fine. When the virus broke out, we were all home beside Yuqi... And brother Xiaoyun was able to bring Yuqi home safely."
"That's good... wait a minute, Yueyue, when did you have a brother? Oh my... Is my precious sister Yueyue finally grown up and found a boyfriend?"
Ningjing laughing sound can be heard on the phone.
"Stop laughing, I really mean it. He's really my twin brother, blood-related, okay? I am not joking."
Yueyue's tone changed to serious as she didn't want any confusion.
"Huh? Mingxu, I thought you told me Xiaoyun was an orphan, right?"
"Yeah, he said he grew up in an orphanage. I remember when we were introducing each other when we first got to the dormitory."
Mingxu's voice could be heard in the background.
"Well, I guess congratulations on finding your long-lost brother!"
Ningjing's voice sounded genuine happiness for Yueyue.
"Ah, so Yueyue really his twin sister? I told you all that nobody can look that similar without being related. I can tell at a glance that they are twin——"
Before Mingxu's voice could finish, Yueyue could hear him yell out in pain from being hit.
"Okay, okay, I'm going out. Take care of the place, okay?"
A door closing could be heard in the background as Mingxu's voice disappeared.
"Okay, the annoying guy is gone now. Well, Yueyue, do you guys have enough food and water? Are you guys stocked up?" Ningjing asked curiously.
"Yeah, I think we just have enough to get by for now. How is the air-raid shelter life going?"
"Well, water is still in unlimited supply, but food is running out, so it's fully rationed now... And our air-raid shelter here can only accommodate ten thousand people, but there are already fifty thousand people."
Ningjing paused for a second, then continued.
"What's worse is there are more and more zombies every day outside. It's almost as if the zombies are starting to walk out of the city."
"That's not good at all. There are millions of people living in the city. If they all walk out..."
Yueyue froze as she imagined all the zombies marching in massive hordes.
"Speaking of the zombies, you know our local officials who have the police and local militia on their side, right?
They wanted the army to refuse refugees who were at the doorstep of the air shelter. Like, isn't that just cruel? Like how are they human? Just leaving people behind like that."
Ningjing's tone increasingly became more and more angry as she continued with the conversation.
"Yeah, that kind of messed up," Yueyue replied.
"Well, the good thing is the army is the one with bigger guns, and before communication was cut off from central government, the last command was to protect as many people as possible.
So they are actually actively rescuing people from the city and accepting more people into the shelter...
Now, we have some sort of power struggle between them. It's just typical infighting that we civilians can do nothing about." Ningjing finally seemed to calm down a little as she sounded hopeless about her situation.
"Wouldn't having more people make you guys run out of food fast?" Yueyue pointed out, thinking back to Ningjing's mention of the max capacity.
"Yeah, so the army has been recruiting people as volunteers to bring food back. Mingxu just went right now to carry some food just now."
"Are they giving out food for free?" Yueyue asked as she became increasingly intrigued by the situation in the air shelter.
"No, people have to work to get food. You either help build walls or go outside. The walls are ten meters high at this point.
Actually, I went to join the search team, but they said that women are not allowed to join. Like how sexist is that?
I'm literally stronger than Mingxu and half of the men on the search team, yet I can't join. What a bunch of sexist pigs." Ningjing complained.
"Maybe there are some other reasons. Don't think too much about it." Yueyue comforted Ningjing.
"Also, let me tell you, be careful when you go out, okay? I heard from Mingxu that the zombies are starting to mutate now."
"Mutate? What do you mean?" Yueyue sounded a little surprised upon hearing the word mutate.
"Well, like, some zombies can jump very far, some can climb walls with their hands, some can even be bulletproof and are so massive it's like the Hulk."
"What? That sounds insane. Is humanity just going to lose to the zombies, then?" Yueyue began to feel a little nervous after hearing about the possible mutations.
"Not yet. Those tank zombies still have their heads as their weak points. A single rocket can blow them up easily. Come on, Yueyue, we still got technology on our side, you know."
"Then don't scare me like that! You could have said the whole thing at once... Oh, I got to go now. Stay safe, okay?"
With a beep, the phone was hung up by Ningjing's side.

Xiaoyun was finally back from the shower and saw Yueyue sitting on a yoga mat.
"Geez, you took a long time to take a shower," Yueyue complained.
"What? It was like only ten minutes ago." Xiaoyun argued back.
"Whatever. Now we are doing yoga."
Yueyue stood up in excitement on the yoga mat as she hurried Xiaoyun to take off his shoes.
"Huh? Is yoga a part of the fitness plan?"
"You want to be a punching bag with no agility? You must have both strength and flexibility."
As the two got on their yoga mat, Xiaoyun decided to warn her about something.
"Fine, I just want to tell you that I am not that flexible at all."
"Even more reason to do it. Okay, let's do some basic stretches. Put your hands up and slowly separate your legs."
Xiaoyun copied Yueyue as she lifted her arms and took a step forward with her left leg.
Ten minutes later...
"Stop shaking. Mom is almost in her forties, and she can do better than you. Come on, man up. Just relax your legs."
Yueyue was speaking louder and louder as Xiaoyun continued to tremble.
Another ten minutes later...
"Now go back to standing up straight, raise your left leg first, and then put your hands behind your butt. Keep your head up and your chest up, and take a deep breath.
Now, switch legs and follow the same movement. Look, you are getting better at this."
Another ten-minute torture session later...
After what felt like a century, Yueyue finally called for a short break. But the break quickly ended as she was already making him move on to the next stretches.
"Okay, break over. The next sets we are doing are going to need two people together.
Usually, I will be doing this with Mom, but since you are here, you are going to take her place. Don't be nervous. It is just like what we did earlier."
Yueyue combined her mats with Xiaoyun's as the two stood close to each other.
"Now, I need you to lie down first, and I'll test the flexibility of your legs first."
Xiaoyun lay down on the yoga mat as Yueyue kneeled on it.
"Raise your legs straight up. Make an L shape with your body."
Xiaoyun raised his leg as told.
"Now I am going to separate your legs apart just a little bit now. Don't be scared. You are not doing a split, okay? I need you to tell me when to stop."
Yueyue slowly pulled Xiaoyun's legs away from each other until Xiaoyun told her to stop.
"Okay, well, the test is over. You aren't that inflexible. Now, let's get down to business.
I am going to need you to grab my calf and lift it as high as you can. And I am going to grab your legs."
Yueyue was slowly lifted into the air as Xiaoyun pushed her by the calf. Then Yueyue grabbed Xiaoyun by the leg to stabilize.
"Now we just have to maintain it for two minutes. Don't let go until I tell you to, okay?"
One minute later...
"Shit, why am I doing this? Her legs feel so smooth, I can barely feel the muscle inside... but she definitely is stronger than me."
Xiaoyun could see Yueyue's white panties underneath her shorts as her legs were right before his eyes.
"No, I need to focus. I can't look at my twin sister like that. I already have Qiqi."
Despite Xiaoyun turning his eye back to the ceiling, a tent was building again.
"He is getting hard again? Why can't he just calm down for a minute? He is such a pervert! Maybe I should just end it early?"
Yueyue's mind started racing as she noticed the bulge around Xiaoyun's pants. But after holding the position for a few minutes, Yueyue finally decided to end it.
"Okay, you can let——Wait, not that fast!"
Xiaoyun immediately let go of her legs before Yueyue could finish talking, causing her to fall.
But she instinctively pushed her hand forward to avoid falling face-first, which made the most painful experience for Xiaoyun.
"Fuck! Shit! Ouch!" Xiaoyun screamed as Yueyue's hand was right on top of his crotch area.
Yueyue immediately moved her hand to the side and sat down next to Xiaoyun, but it was too late.
"I'm sorry, I'm sorry. I didn't mean to do this. I'm so sorry." Yueyue apologized as she started to fear what she had done to Xiaoyun.
"I can't feel it anymore! Fuck!" Xiaoyun rolls in agony with his hand on his crotch as it starts to get more and more painful.
"I'll go call Mom——"
Before Yueyue could leave, Xiaoyun grabbed Yueyue's hands.
"Please don't. I don't want her to deal with more problems... Can you turn around for a second?"
Xiaoyun let go of her hand as Yueyue nodded in agreement. After Yueyue turned around, he slowly took off his pants and underwear.
"Fuck, this is not good..."
His cock was slightly bent sideways, and he couldn't feel or even get erected anymore, no matter how hard he tried.
"Brother, are you okay?"
Yueyue worryingly turned back around before Xiaoyun said so and saw his cock had completely softened.
"I think it's just some blood vessel popping. It should be fine later."
Xiaoyun offered a reassuring explanation, but he was completely unaware that Yueyue had turned around as he was still focused on his injury.
"It's all my fault. I accidentally crushed it. I'm so sorry."
Yueyue moved a little closer and apologized to Xiaoyun again, making Xiaoyun finally realize she had turned around as she was sitting almost right next to him.
"It's fine. It's just an accident——Shit!"
As Xiaoyun tried to put on his underwear, he accidentally pushed it too hard, which made it even more painful.
"Are you sure I don't need to call Mom?" Yueyue nervously asked as she became increasingly worried.
"Yeah, I am good——Fuck!" Xiaoyun groaned in agony again as he put his pants back on.
"Just if okay? If you can't get it up... I will take care of you." Yueyue replied as she looked towards Xiaoyun's face with a serious look.
"Don't worry about it. How are you going to take care of me if you are my sister?" Xiaoyun joked to lighten up the mood a little.
"I mean, like, if you can't find a wife in the future because of it... I-I will marry you... like if that happens, okay?"
Yueyue blushed and lowered her head as she couldn't believe what had just come out of her mouth.
"I am just joking. Please don't take it seriously." Xiaoyun clarified as he realized she was taking it seriously.
"I am serious..." Yueyue murmured.
"Ahem, anyway, it's fully recovered now," Xiaoyun replied after remembering his ability, so he simply changed it back to its original state before the accident.
"You don't need to lie to me like that just to comfort me."
Yueyue's face was full of guilt as she didn't believe Xiaoyun's words at all, as the injured cock was melted into her brain.
"I really mean it. I am not joking."
Despite the reassurance, Yueyue still didn't believe it at all after taking a glance at Xiaoyun's crotch and noticed it was still completely flat.
"How can I prove to you that it's fine? Like seriously." Xiaoyun asked, noticing Yueyue was still not convinced.
"Then why is it not hard then?" Yueyue murmur.
This time, Xiaoyun was able to hear Yueyue's murmur and realized the misunderstanding.
"I can't just get hard randomly like this," Xiaoyun explained, but it made the misunderstanding even worse.
"How about this then?" Yueyue replied as she suddenly took off her shirt and bra, exposing her breasts for Xiaoyun to see.
Just as Xiaoyun thought earlier, it was roughly half of Yuqi's size. But he immediately turned their head as he thought back to Nami's words and Yuqi's confession.
"Sorry, I can't do this."
"Why not?" Yueyue was confused by Xiaoyun's sudden change as he avoided looking towards her.
"I just can't, okay? You are my sister." Xiaoyun explained as he closed his eyes to avoid the temptation to look at Yueyue.
"Then why did my brother get hard when lifting weights and doing yoga? I know you were staring at me when my bra was transparent. Why not look at it now?"
Hearing Yueyue point it out, Xiaoyun feels even more guilty and covers his eyes with his hand.
"I am sorry for earlier, but I can't do this." Xiaoyun apologizes.
"Fine then, I will just do it myself."
Xiaoyun was confused by what Yueyue meant until he suddenly felt someone taking off his pants and underwear.
"Please stop, we shouldn't do this."
Xiaoyun immediately opened his eyes back up and tried to push Yueyue away, but Yueyue immediately held onto his cock with her hands.
"I am just checking if you are lying or not, okay? You should thank me for doing this."
Yueyue hesitated for a second but then made up her mind as she began stroking Xiaoyun's cock.
"Yueyue, we shouldn't——"
Xiaoyun couldn't help but let out a small moan as Yueyue peeled back the foreskin.
"Shut up! Do you think I want to do this? I just don't want Mom to find out that her son can't get it up because his twin sister crushed it...
I just need to make sure it can get hard to satisfy your future wife. I'm not ending our family line."
Xiaoyun gave up trying to convince Yueyue as she continued stroking it up and down.
"It's not getting bigger. It just stuck half limp like this. Why?"
Yueyue looked confused as it didn't look like what she had seen in the manga book she read before.
"You are stroking it so roughly... Besides, I just came four times earlier with Qiqi," Xiaoyun murmured, quieter and quieter to the point only he could hear.
"Shut up. How am I supposed to know? I've never done this before," Yueyue argued as she slowed down and started gently stroking it as Xiaoyun advised.
Slowly, Xiaoyun's cock was finally beginning to get erected.
"Look, it seems to be getting hard! Thank god it's fine now."
Yueyue let out a sigh of relief as she could feel the hardness of Xiaoyun's cock in her hand.
"Can you stop now?" Xiaoyun asked as he was starting to feel guilty for cheating on Yuqi.
"Not yet. What if it can't reach climax? I can't be the one that ends our family bloodline. Our grandparents would have killed me if that happened."
Yueyue refuses to let go of it as she continues to stroke his cock with her hand, clearly wanting to see it ejaculate.
"I have to stop her before it gets worse. I am better than this. I can't fall into temptation." Xiaoyun thought to himself, but his main weakness was right in Yueyue's hand.
All of a sudden, Xiaoyun's cock was slowly getting softer again as he resisted it in his head as much as he could.
"Hey, why did it soften again? Did I not do it well?"
Yueyue got a little confused as the cock was now half limp again.
"It's not you, it's my problem. Let's just stop." Xiaoyun replied in a depressed tone.
"Wait, why?" Yueyue asked, but Xiaoyun didn't respond.
Immediately, it set off red flags in Yueyue's head as her mind started coming up with reasons for it.
"Is he still injured? Or maybe he's just not in the mood? Or perhaps... Does Brother Xiaoyun have erectile dysfunction?"
Yueyue's mind slowly started leaning towards the last conclusion as she felt the first two made no sense after seeing it hard earlier.
"Brother, don't be sad. If I remember correctly, this is curable... From the manga I read, I think it just needs more stimulant."
Yueyue got the completely wrong signal as she kneeled in front of Xiaoyun, with Xiaoyun's half-limp cock in front of her eyes.
"Yueyue, stop. Are we misunderstanding something? What are you talking about? What cure?
What kind of manga do this kind of stuff? You're taking this way too far——"
Despite Xiaoyun trying to leave and get out, he couldn't move at all as Yueyue held onto his cock even tighter.
"Brother, don't worry, I'll cure you. Just let me handle this."
Yueyue has finally made up her mind as she holds her breasts with both hands and then wraps around his cock between her cleavage.
"You——"
Xiaoyun was completely dazed by what Yueyue was doing as she began squeezing her breasts around the soft cock and stroking it up and down, making Xiaoyun feel as if he was entering a real vagina.
After so much stimulation, it was finally fully erected and stood above Yueyue's breast, reaching all the way to her chin.
"Brother, you're hard again! It's a success! I did it!" Yueyue cheered in excitement as if she had made a major accomplishment.
Something snapped in Xiaoyun's head as he threw everything out the window, no longer caring if he was feeling guilty or not.
"It's so hot, I can feel it. It's so big and long... If this thing goes inside me... No, no, no. What am I thinking?
I'm just helping my brother cure his illness. I am not doing anything wrong." Yueyue's mind started having different ideas as she couldn't control her mind with a cock still between her breasts.
As Yueyue continued squeezing Xiaoyun's cock inside her breasts, Xiaoyun was starting to reach his limits.
"Enough is enough. Yueyue, I can't hold it anymore." Xiaoyun decided to warn Yueyue, hoping that she would let go of it as the realization kicked back into his head.
But Yueyue seemed to be too deep in her mind as she didn't respond, and her hands were still moving her breasts.
"Yueyue, stop!——I'm going cum!" Xiaoyun yelled out as he finally couldn't hold it any longer.
Yueyue finally snapped back to reality after hearing Xiaoyun's warning, but it was far too late.
"Huh? Wait——"
Before Yueyue could move, Xiaoyun's semen started spraying out onto her face, with some even getting inside her mouth as she opened her mouth to talk.
"Yuck, is this what semen is like? It's so salty. Why would anyone swallow this in those manga?"
Yueyue tried to cough it out but just accidentally swallowed it down a little. Only when Xiaoyun stopped ejaculating did she finally catch a break.
Her face was now completely covered in his hot semen, with her lips and her hair having semen all over it.
"Can you tell me in advance next time? Wait, there is no, there is no next time. Ugh, my face is so damn sticky."
Yueyue tried to reach out for a towel, but she couldn't see at all as the semen was on top of her eyelids and eyelashes.
"I did, but you just kept going," Xiaoyun argued as he got up and took a towel to help her wipe her face.
"Well, at least we know you are all good now... Let's keep this a secret between us. I don't want anyone to know this, okay? You don't want it, too, right?"
Xiaoyun nodded in agreement as he didn't want to ruin his relationship with Yuqi.
As Yueyue was finally able to see and stood up from the yoga mat, she realized most of the semen was actually inside her cleavage as it was full of semen.
"Crap, this is not good."
Yueyue quickly grabbed another towel and started wiping it before they all fell onto the floor.
Seeing Yueyue still half naked and covered in his cum, Xiaoyun could feel he was getting hard again. So he tried to cover it with his hand and walked a step toward the underwear.
"Brother, um, I'm going to the restroom, bye!"
Yueyue noticed Xiaoyun was getting hard again, so she picked up her shirt and bra and ran out of the gym.
"I really did it again... I really fucked up again. Why didn't I resist her? What would Yuqi think if she found out about this?
Am I going to lie to her? I really just did what Nami asked me not to do... Why didn't I just push her away?"
Xiaoyun reflected on himself, only to find no answer. But after looking at the gym again, he noticed there was semen everywhere on the mat and floor.
"I guess just kick the can further down the road... My future self is going to hate me for this..."
Xiaoyun immediately created a mop and bucket and began wiping the floor.
---
Meanwhile, Yueyue managed to sneak past Leyan, who was in the kitchen cooking lunch and get all the way back into her room.
After picking up fresh clothes, she immediately rushed to the restroom.
Yueyue looked at herself in the mirror as she took off her pants. The semen on her breasts was beginning to dry out, and her clothes smelled weird.
"It's so sticky and smelly—wait a minute, didn't I touch this earlier?"
Yueyue suddenly realized the white liquid looked awfully familiar to the one earlier.
"The white liquid... was semen? Then that means the blood is... Wait, Yuqi gave her first time to him? No wonder why she is so tired and hiding in her room all day..."
Yueyue slowly connected the dots in her head when she realized Yuqi's secret.
"But they are siblings! Why would she do that?"
Yueyue stood still in the bathtub in shock. She couldn't believe her own older sister would do such a thing with her twin.
"I need to tell Mom about this before they make any more mistakes."
Yueyue stepped out of the bathtub but stopped as soon as she got to the mirror.
Her breasts were still full of her own brother's semen, with some starting to get all the way down to her legs.
A defeated Yueyue walked back into the bathtub and began to shower.
"Do I have the right to judge her? I just did this kind of stuff with him. What am I supposed to do? Just let them continue?" Yueyue wondered as she started scrubbing the semen stain with soap.
"I mean, Qiqi looks so happy today. They are both adult and mutually consented... Wait, did I just become brother's mistress?"
Yueyue realized why Xiaoyun was so hesitant to do it with her, but she didn't think much of it.
"No, no, no, I was just curing him, and it's only a one-time thing." Yueyue scrubbed it a little harder as she tried to convince herself.
"I wonder what their first time is like... Wait, when did I become so bold and lewd?"
After finishing taking a shower, Yueyue looked at the white semen and hair stuffed into the filter cap, the same way from earlier.
"It's my turn, huh." Yueyue laughed at herself as she picked up the hair with her hands.
---
After sneaking past the living room and the garage, Yueyue walked to the laundry room with her in the laundry basket.
There were already clothes inside the washing machine. All of them were Yuqi's clothes, just like she predicted.
"I knew it. My theory is right..."
Yueyue took Yuqi's clean clothes out of the washing machine and put them in the dryer. Then, she loaded her own clothes into the washing machine and started it.
"Yuqi only knew him for a few days. What did Xiaoyun do to make the Yuqi fall in love with him and even be willing to give him her virginity?
Did she really fall in love with him, or is she just thankful that he saved her?" Yueyue thought for a while but couldn't come up with an answer.
