I've posted this chapter months ago in Ao3 but updating it here completely slipped my mind and I realized it just now

Time passed and Shirogane eventually finished his daily duties as their school's president, he sighed in relief as he relaxed in his chair "it's finally done" he said before turning his attention around the room,

Unlike earlier though they weren't there anymore which is expected since they probably went to their classes earlier and he was too focused to notice them leave.

'I better get going too then, I'll just talk with Shinomiya later' He enthusiastically said to himself as he carried his bag and went on his way to his class.

The day passes like normal but yet shirogane couldn't find a chance to secretly ask Shinomiya out as she has oddly been with Ishigami for the majority of the day and apparently they had plans after school too, honestly shirogane would feel very suspicious of them if only he doesn't know them well enough.

'There's no way Shinomiya would cheat on him and Ishigami is like a brother to him, he would never betray him' Shirogane thought confidently as he get mad at himself for even considering it, "I'll just call her later" he quietly muttered to no one in particular.

Meanwhile, the two suspected individual casually flirt with each other in secret as they walked under the beautiful dark sky full of bright stars, they were like a couple sweetly holding hands entrance by each other's presence.

Thankfully, there wasn't any people that knows who they are as they chose a way home that not many people uses, they're on their way to go to Shinomiya residence this time around to continue their lust-filled sex earlier in the student council room.

Of course they wouldn't be able to do this without the help of Kaguya's reliable maid Hayasaka, she's the only person other than themselves who knows about their relationship, at first she was in dismay when she learned about it but she eventually decided to help in their illicit affair.

This may be wrong but she will fully support her against her better judgement, Kaguya has always been tightly tied by rules of her family so seeing her freely doing things on her own was one of Hayasaka's long life dream no matter how wrong it is.

What's more, it's seems like her contractor who she treats as her troublesome little sister is really enjoying to be with Ishigami not just sexually but also romantically, she doesn't seems to realize it yet though neither does he but it'll just be a matter of time.

Hayasaka felt genuine pity to Shirogane as she certainly knew this debacle wouldn't end well for him but nonetheless she'll still help Kaguya if she so desire to be with Ishigami.

In fact, she's currently observing the two who's lovingly walking from afar as she prevents things that might reveal their secret.

Thankfully, Kaguya and Ishigami managed to arrive at the mansion without a hitch, unsurprisingly they immediately made their way on Kaguya's extravagant room with it's huge soft comfy bed, they started stripping each other as if they just didn't fucked each earlier that morning.

"Ah Ishigami, kiss me!"

"No need to tell me that, senpai"

Their lips smack against each other's the moment they finished unclothing, Kaguya then pushed him on the bed and eagerly came on top of him.

She wasted no time and swiftly guided Ishigami's thick cock through her pussy, a plethora of pleasure exploded as the tip of his dick touches her delicate womb.

Kaguya just couldn't get enough of this happiness and seeing Ishigami's smile brings extreme joy to her, she smiled before finally going down and up on his glorious cock.

Her moans was so loud that it could be heard in the hall outside of her room, fortunately Hayasaka had foreseen this and had already told the other servants not to go near Kaguya's room nor should they be in the hall towards it. (She's just right outside the room guarding in case someone tries to ignore her orders)

An hour of a loud sound of sex goes by and they were yet to stop until Kaguya's phone rings which promptly snapped them out.

"Brriiingg! Brriiingg! Brriiingg! Brriiingg!"

"Pardon my intrusion" Hayasaka said before entering the room, Both of them just looked at her which she ignored as she picked up Kaguya's ringing phone "it's Shirogane-san, would you like to answer it Kaguya-sama" she asked professionally as she tries to ignore Ishigami's surprisingly well-endowed body, now it's no wonder how he managed to seduce Kaguya.

"Ummm... Answer him and tell him I'm not available right now" Kaguya said smugly as she looked at Ishigami.

"As you wish, Kaguya-sama. Now if you'll excuse me" Hayasaka bowed before once again leaving them alone.

"Well, now that that's taken care of, shall we continue" He said with just as much smug as she had.

"Yes please" Kaguya playfully replied.

That was the only interruption they've got as they proceed to fucked like rabbits all night long.

As the first rays of sunlight peeked through the curtains, Ishigami sleeps soundly on a cozy soft bed. It was a tranquil morning, with a gentle breeze rustling the leaves and the melodious chirping of birds filling the air. He gently opens his eyes upon realizing the wet feeling his getting in the lower part of his body, there was also this erotic sounds.

It's a familiar pleasurable sensation that he came to be accustomed to for these past few weeks, he looked down to see a big bump on the sheets so he took it off revealing Kaguya face down sucking his cock seductively between his thighs.

"Ah senpai?"

She looked at him feeling pretty pleased at herself to see his blushing cute face, she continues to slurp his dick and get her morning milk right from the source.

"Yes, oh my god this amazing, Shinomiya-senpai"

Kaguya hearing that, intensifies her fellatio as she went down and up on Ishigami's dick faster than before doubling the pleasure.

"Please don't stop, ah god is this heaven?"

She loved the way he tasted. Kaguya had sucked Ishigami's cock more times than she kissed Miyuki so she knew exactly where to lick and what pace he likes the most. He softly moaned and blushed even more than before. She made lazy circles around his sweet head and his moaning became louder.

A few more minutes passed before Ishigami finally ejaculate and filled Kaguya's mouth with his fresh new cum that she so desires.

"Mhm, I really love your taste, it's so addicting" she said feeling proud of herself while she licks the cum on her lips.

"You're incredible senpai, that's a really amazing way to start the day"

" Yeah right, I saw your erection and I couldn't help myself teehee"

They both laughed at their interaction before locking eyes and starting another marathon sex in the morning.

Meanwhile, Hayasaka were also now again Infront of Kaguya's room being as diligent as ever "they're at it again, where are they even getting that energy" she muttered to herself while hearing Kaguya's moans and the creaking of the bed.

She knew she'll get to have to deal with this eventually but she never have thought that it would be this soon, especially since Shirogane is not the straightforward type of guy but well, she didn't took into account that it'll be Ishigami that got to take Kaguya's virginity.

"Does it really feels that amazing?" Hayasaka bashfully whispered as she subconsciously started fondling her tits with her right hand while her left touches her pussy, putting two of her fingers into her folds.

The constant wild lovemaking of the two lovebirds is starting to get into her, she imagine how it would feel for Ishigami to fuck her brains out, how it would feel kissing him with her tongue entangled with his.

She imagine herself in Kaguya's place getting absolutely nailed on the bed by him, Her finger move faster upping her pace as she heard their lust-filled moans together with the slapping sounds of their skins hitting with every thrust.

Hayasaka as professional as she is though, never dared to secretly peak on them. Masturbating right Infront of the door from their lovemaking sex is already shameless enough.

"Uuuwwaahhh...! Ishigami-Kun!...Ishigami-Kun! I love you! I...want you to fill me up with everything you have inside! Pleeease!~" Kaguya cried out, making Hayasaka snap out of her lust-induced trance and visualize herself in saying the same thing.

Just then, the girl flicked her exposed clit and wound up making herself cum all over her fingers with her moans barely being stifled behind closed lips!

"Mmmmnnggghhhh!!" She hummed loudly, praying for the strength to keep her screaming quietly while hearing Ishigami howl loudly in euphoria as he unloaded his cum as deeply as he can into Kaguya's womb.

Kaguya's legs began quivering slightly with her entire body becoming wracked with orgasm, Her eyes rolled back up with her tongue out like a dog as Ishigami pumped her baby-maker full of sperm!

Splurt...splurt...splurt..splurt...splurt...splurt...splurt...splurt...splurt!!*

A few seconds passed before Hayasaka immediately regain her composure and begun fixing herself up, she then just stand there calmly as she was before like nothing happened.

"I'll really never get tired of this, I kinda feel bad that Kaichou has never get to experience this yet" Ishigami thought as the lustful predator inside of him howled.

"As you should, you stole his chances and now he might never get to experience this" Kaguya smilingly retorted.

"Hehe you're kinda right but it's not my fault that you offered it to me first" Ishigami teased back.

"I just asked you to teach me... is what I should want to say but yeah you're right" She openly admitted while giggling "there's really just something so arousing in cheating behind his back, don't you think? Ishigam-kun"

"Damn Shinomiya-senpai, you're way too horny"

"I don't wanna hear that from you who told me about practice sex, I feel stupid even believing it" Kaguya pouted faking her frustration, that was the reason why she can get to enjoy cheating sex with Ishigami right now so how can she even be mad about it.

If ever, she feels so delighted about it that she recalls it everytime she's not having full on wild sex with Ishigami, a truly horny cheating girlfriend.

"It's cheating sex now though, an amazing one at that" Ishigami grinned looking at her trying so hard not to smile back which she failed.

"Gosh you're being too cheeky, you know that?"

"How can't I be when I fucking the most popular girl in our school who's also the girlfriend of my well-respected senpai, Kaichou"

"You're terrible in enjoying this... And honestly so am I" Kaguya smiled wickedly.

"You seem awfully proud of yourself for someone who's terrible, I like it" Ishigami said pulling her towards him "how about another round"

"You bet" Kaguya said before interlocking with her tongue with him while they simultaneously slurp each other's saliva.

"I'll makes sure Kaichou's sacrifice wouldn't be in vain, I'll fuck you so he wouldn't have to" Ishigami naughtily said as he slam his cock back into where it rightfully belongs, Kaguya's tight wet dripping pussy.

He is set on stealing Kaguya without feeling any remorse for his friend, He continuously slammed his hips into hers as their bodies rubbed together.

"Oh please!... Ishigami-kun, don't stop! Please make me yours" Kaguya loudly moaned followed by erotic sounds of passionate kissing.

"Oh hell yeah, I will!... I better thank Kaichou too once we see him again as I get to have you because he wasn't fast enough"

"ah that's... Terrible, I love it" Kaguya is reaching the peak of orgasm and so is Ishigami as they continue to spit on shirogane, They hasten their pacing as they feels each other reaching orgasm without having to say a word.

They fucked so many times now that just looking at each other's eyes were enough to know, they hugged each other tightly as Ishigami slams his final thrusts releasing his white hot cream into Kaguya's flooding wet cunt.

He pumped her full of semen "oh really thank you Kaichou" He said as he let out the last batch.

They catch their breath while still in a tight embrace.

"Ishigami-kun, I think I'm really falling in love with you"

"Same with me, Shinomiya-senpai. I love you... Romantically"

"You really stole me from him heh, you cheeky kouhai of mine"

They both openly flirt with each other but this time it's romantic instead of just sexual tension "what are you planning to do now then?" Ishigami asked Kaguya.

"Well, I can break up with Kaichou but I think things would be awkward especially if he learns about us so probably not now and... wouldn't it be more exciting stay this way, us fucking behind his back with him clueless at all" Kaguya suggested casually smiling at Ishigami.

"I guess you're right, you can just break up once he get to Stanford" he agreed " I gotta admit though, that's too devious even for us"

"Since I already cheated on him anyway, why not enjoy it to the fullest, right?"

Ishigami chuckle with her "God, I feel so lucky to have you"

"Yeah, not as lucky as I am though" Kaguya retorted.

"Yeah I doubt that" Ishigami leans and kisses her lips gently "by the way can we get some breakfast, I'm starving"

"not me, you just filled me up so I'm really full right now" Shinomiya said jokingly which made Ishigami laugh.

I went really wild with this, I hope you enjoyed it.

I'm gonna add this just in case, it's not that I'm abandoning this story but it'll definitely take a long time for me to update again so if you want to adopt it, I'll be completely fine with that.
