Even though Yoru knew what was going to happen, he was still a bit surprised when Shiiko suddenly hugged and kissed him. Shiiko even uses her tongue and kissed Yoru so deeply.

[I think you should satisfy her. What happened to her might be the same as Ayaka's change in character who became so obedient. And she's getting so perverted.]

'Maybe I should satisfy all those who become my pets. Whether in terms of sex or something else. And It's just coincidently that now is sex that Shiiko needs.'

Yoru then lifted Shiiko who was still kissing him towards a table. After sitting Shiiko on the table. Yoru began to take off the lab coat and clothes Shiiko was wearing. After that, Yoru started squeezing and playing with her nipples.

Shiiko then took off her own pants and after that she took off the pants Yoru was wearing. Yoru then started sucking Shiiko's nipples and used his hand to play with her other breast and his other hand to play with her pussy. And Shiiko herself also started giving Yoru hand jobs.

Ah....

Um...

"Yes... Deeper please..."

Ah...

"There..."

Uh...

"Ah... Wait... If you do... My pussy and nipples at once... I can't..."

Ah....

Ahhhhhhhh.....

Shiiko ejaculates heavily. She immediately went limp and fell into Yoru's arms without a fight. Seeing Shiiko so helpless made Yoru a little horny. He then decided to insert his penis without a second thought.

Ahhh....

Shiiko immediately felt Yoru's penis entering her pussy and made her twitch.

"Ahhh.... I just... cum... I'm still sensitive...sitive." Shiiko said with irregular breaths.

"But, I'm not yet cum thought." Yoru said with a smile.

He then moved his hips rapidly.

Ah.....

Uh....

"Slo...w...don...plezzz...I can't...."

Ah....

"It's coming again... Ahhhhhhhh...."

Shiiko ejaculated again, but Yoru didn't stop, he moved his hips even faster.

"Ahhh... Let... Me... Rest... A... Bit... Ahh...."

Ah....

nggg....

"Wait..."

Ahhh....

Ahhhhhhhh......

"I almost came too."

Ah....

Mmm...

Nnngggg...

"Shiiko..."

"Inside... Rele..ase every...thing... inside... fill me up..."

Hggg...

Hmmm...

nggg...

"I'm cumming..."

"Me too..."

Ahhhhhhhh.....

Uggg.....

Ahhhhhhhh.....

Both ejaculate simultaneously. Yoru released so much sperm into Shiiko's pussy and made her stomach swell a little. But because Yoru still feels that he is still producing even more sperm. He decided to release the rest into Shiiko's body.

Shiiko's body was drenched in sweat and the sperm Yoru released. And her body also convulsed and Shiiko herself could only stare blankly at distance.

"Ah... I did it again." Yoru scratched the back of his head.

[Huhf... Did you forget the amount of endurance you have now]

"Sorry... I better take a shower before we leave the lab." Yoru looked at the condition of his body and Shiiko's body.

Because Shiiko was still unconscious. Yoru decided to carry Shiiko towards the bathroom. After that, Yoru bathed Shiiko's body and cleaned up nook and cranny of Shiiko's body.

After Yoru done with washing Shiiko's body, he leaned Shiiko's body in the bathtub and he himself started cleaning his own body.

Not long after that. Shiiko regained consciousness and was a little surprised because she was in the bathroom. Shiiko looked around and immediately calmed down after seeing Yoru there as well.

"Owner. You really have no mercy." Shiiko slightly scoffed.

"Ah... you're awake? And don't call me owner." Yoru turned his head and saw Shiiko with a slight frown.

"But you enjoyed it right?" Yoru replied to Shiiko's taunt.

"Indeed, but it was too much. My groin still hurts a little."

Yoru who finished cleaning his body then entered into the bathtub and hugged Shiiko from behind.

Shiiko then turned her head and kissed Yoru. But not long after that he broke the kiss and pouted a bit.

"If it's like this, it looks like you need to find another woman to help me satisfy you." Shiiko said after she felt something hard touch her buttocks.

"Ahahahaha..."

"Don't just Ahahahaha... If I'm alone I will lose eventually."

"Actually I've already had three wives. And one more in the same position as you. But I haven't had sex with this one yet." Yoru scratched the back of his head.

"5 including me? Looks like it's still lacking. Search again." Shiiko looked serious.

"Eh..." Yoru's face turned a little weird.

"With you letting out as much as before and still this big and hard." Shiiko then squeezed Yoru's penis.

"Arrgg... Be a little gentle..."

"I passed out and cumming several times and you only cum once. Of course 5 is still not enough. I have a friend who works at Mochizuki General Hospital, when we get there I'll introduce you to her. I'll help her join us later." Shiiko said.

Shiiko then stood up and out of the bathtub. Yoru also followed. The two then dried their bodies, and got dressed.

"I better bring all the data."

"Need help?" Yoru was a little unsure of what to do.

"Could you please kill the zombies that are in that room." Shiiko pointed at a door with a "Do not enter" label.

Yoru then entered the room and came out after a minute after he killed all the zombies there.

After Shiiko finished copying all the data and stuffed everything she needed into her bag, she was ready to head out.

After leaving, the two of them went straight to where Yuriko was. But after the two of them arrived, the tent where Yuriko was located seemed crowded.

"What happened?" Yoru said after he managed to enter.

"Yoru." Souichiro looked pleased after he saw Yoru.

Not just Souichiro. Tadashi, Yuriko, Kiriko, Hanako, Takashi, and Ayaka looked relieved as if their burden had just been lifted.

"What exactly happened? Why are you all here?" Yoru is still confused.

"I have bad news. Kouta, can you explain everything." Souichiro was silent a bit before calling out to Kouta.

Kouta then approached and was a little surprised.

"Shii-nee?" Kouta said after seeing Shiiko standing beside Yoru.

"Oh... Kouta, you are safe?" Shiiko was surprised for another reason.

"Of course. Although mostly because Yoru-san helped. You know each other?" Kouta looked at Shiiko and Yoru in turn.

Shiiko just smiled. She then looked around and stopped at Ayaka.

Ayaka who saw Shiiko looked very angry. And Shiiko then smiled slyly.

After that, Shiiko hugged Yoru and kissed him on the cheek. "I think we are more than acquainted."

"Wha... You bitch!!!" Ayaka furiously jumped up and tried to hit Shiiko.

But Yoru smoothly caught Ayaka and separated the two. Ayaka tried to struggle. But after Yoru flicked her forehead, Ayaka fell silent.

"We have a problem here. Don't create another problem."

Ayaka could only lower her head.

"And Shiiko, you shouldn't provoke Ayaka either."

Shiiko stuck out her tongue.

"Huhf... Kouta, is Shiiko your niece?"

Kouta nodded his head.

"Ah... Then, from here on, you should call me nii-san."

Kouta and the others couldn't help but stare and gape.

Ayaka still pouted slightly. But calmed down after Yoru stroked his head.

"Then what's our problem?" Yoru said seriously.

Kouta was a little surprised but still managed to answer right away. "Many zombies are coming here. And the number is more than when we have at Saya's house."

And after Yoru heard what Kouta said. A notification appears.
