Fair warning kou is going to be more possessive yandere because... well you'll see.... 

*Kou was still greedily sucking your blood, becoming like a addicting drug the taste of it intoxicating the woman he loved loved him back that woman is you not yui not anybody but you and you alone*

Meanwhile ruki finally managed subdue ruby get her far away from Shuu and honestly they were in some kind of love hotel kou had givin him some pocket money so they could get in for a night or 2 yea ruki needed her again like she needed him and he had to overide what Shuu did to her before it was too late...

Back with you and kou

Kou had taken you back to his room he teleported the two of you far away from the school and directly to his room he couldn't exactly hold back right now as he wanted to

(Short note if there is any signs of a lemon then the lemon will be in the next chapter but it will be short 

Kou Was still holding back as he thought of what ruki could've been doing... a part of him seriously loved him so hard but he couldn't just drop you for him he'd never do that.... But a part of him also wanted a 3some with you and him so he can suck ruki off while he makes love to you and again he'd be ruthless with you never giving you any chance to breath 

Just thinking about it made him hard... which he had to take care of as soon as he could before you noticed it... ~

He cursed under his breath he had to do somthing he thought to take a shower but didn't want to worry you...

"Can you please not do anything too sudden I'm super sensitive right now you know~" he said kissing your neck suddenly pining you against the wall in an instant the kissing turned into softly sucking which turned into a deep bite and sucking blood "...fufu*gulk gulk* so sweet M-Neko-Chan~ I want more~ "

he moaned out slowly sinking his fangs deeper into just where your neck meets your shoulder giving him enough space to plunge his fangs so deeply they almost penetrate the bone but not quite, his fangs are extremely sharp though~

somehow just drinking your blood made him calm. Down which was good because he didn't want you to notice his issue... not so early at least...~

He wondered what was going on with ruki and ruby now

-meanwhile-

Shuu was looking around for ruby when he realized where she probably was "damnit if your with ruki ima loose my damn mind! 

He said without any regret about anything at all... though he regretted leaving her alone where he could get to her ... he hoped he wasn't too late though...

-Meanwhile elsewhere-

"Chichinishi damn this feels way too good to be true how can sombody so small feel so good~" he said ... (for lack of stuff this will be revealed in chapter 5 ) 

With Shuu ruby and ruki

"Get your hands off of ruby shes mine ruki~ she's too far along for you to mess it up any way~" he said holding her possessively

"You don't mean~" ruki wanted to cry it couldn't be true he respected Shuu but he wouldn't stoop so low as to take away another chance to give her children ....

"Yea vet said that they would be tabby she's due to transform any day now...." He said thinking

"What do you mean transform?" He asked

"I mean when she is pregnant hell when any neko is pregnant they usually shift to their cat form unless they were born without one which in y/n's case that is what is going on with her she was born a human neko ruby was born half neko which means she can shift to her cat form whenever..." he explained making ruki gap his mouth wide open 

Meanwhile (slight smut warning the real lemon will start in the next chapter but again kou can barely control his lust right now even if he got it under control for the most part...) 

Kou pinned you against the wall of his bedroom his fangs getting a better angle where he bit you next giving him more access to your precious (blood type) blood as it made his throat burn with a fiery passion "goddamnit m-neko-Chan why is it so hard not to take you right now?!" He asked moaning into your neck feeling himself get hard again

"W-what do you mean take me?" You asked innocently

"Don't tell me you haven't seen yui and ayato let alone ayato yui and laito do it to her?!" He asked seriously looking into your eyes full of lust and desire

"Your holding back aren't you? Also yea I still don't get it" she said

"Goddamnit youuu!!!! They make love to her and then they torture her..." he said

Kou blushed at what he said "but you know -o-

"Kou-kun~ please" she said her tail standing on end "please bite me harder and d-deeper~"

"As you wish pretty flower~" he said as he waited for sombody to help him with her and dirty stuff he kiss she knows what it is but still*

*blushing* my- y-yeah-yyy

Kou's face was still red how desperately he wanted you was almost too hard for him to handle as he would ultimately have to face it anyway... he would though hopefully after a while he hopes he wouldn't break not after all you two had been through...
