It has been 3 days since their "practice sex" in the student council room and they're yet to go at it again as their occupied in studying for their school exam.

They did both masturbate each other during or after their lovely study session under the pretense that experiencing it more than once is part of their Sex education.

there was just no way they'll be able to completely stop but their last remaining self-control managed to atleast stop them for going on full marathon sex, atleast for now as they can't risk getting too distracted by it.

Kaguya tried to masturbate alone but she just can't satisfy herself, it's not the same as when ishigami is doing it to her and she's not sure why, it's not like she's doing anything different from how he does it, maybe it's simply the fact that it's him that makes it feel so good.

Ishigami is having the same problem, it wasn't like this before but he figured it just the way it is, you can't just expect to feel that extremely intense sex and then be able to go back in masturbating as if nothing happened.

Days flew by and they spend it just like they normally do, they do fun shenanigans that's mostly initiated by Fujiwara and classic friendly bantering between them, it's really fun but they do feel kind of awkward when talking to Shirogane, they fucked behind his back and they honestly have no plan to stop yet, neither of them want to.

'It can't be helped and it's just practice anyway' both quietly thought to themselves as they look forward on the day of the exam and the following days after it

Soon enough, that long awaited day had surprisingly passed more quickly than they expected and it's now already afternoon (almost evening), they were of course both thinking of immediately getting into it but it seems like they'll have to wait this one more day as Shirogane invite them all including Iino and Fujiwara to some drinks after such a stressful day of the exam, they couldn't refuse it as they felt that that will be too suspicious so they just decided to go with it

They have tomorrow all for themselves afterall and they're already have a place in mind as they already talked about this a few days before, there's various different ways to enjoy sex and Ishigami is planning to teach it to her in their home, his parents is currently on a business trip so he's pretty much alone in their house.


The Next Day

Kaguya is now Infront of Ishigami's house, it's still 7 in the morning but she's already eager to start, she has been fantasizing about this for days as she patiently waited and here she is now, just imagining how Ishigami will dominate her this time is already making her pussy soaking wet, her sense of justification is nowhere to be found as she completely forget her reasoning about how "this is all just practicing"

She ring the doorbell once and waited for him to open the door, a few seconds passed before it slowly open showing Ishigami's face that have the same look of anticipation as Kaguya, they both looked at each other.

Ishigami opened his mouth about to say something.

But Kaguya couldn't hold back anymore, She immediately smashed their lips together assaulting the inside of his mouth with her tongue, her arms folded around his neck and her legs around his waist.

Ishigami was again caught off guard but just like the first time, he gladly intertwined his tongue with her as they exchange each other saliva, he stepped back a few steps to close the door while still completely interlocked with her.

The kiss was so passionately erotic that it lasted for 5 minutes straight before they break off with each other's tight embrace, their face is a complete mess of horniness and you can see a string of saliva connecting between their two lips.

"That was so hot" Ishigami smilingly said

They wasted no time as they hurriedly started unclothing, they can't wait for another minute of not being able to fuck each other, Ishigami had now took off his underwear showing his 8-inches long cock, he then helped Kaguya take off her bra which is also her last piece of garment on her.

Kaguya quickly grabbed his pull hardened hot cock and begun stroking it up and down which made Ishigami quiver as he felt her smooth hand on his dick

He answered back by fingering her.

"Ughh" she moaned before Ishigami rejoin their lips together, Kaguya then strokes him faster and faster trying to get the control back, they were like a pair of wolves that are both in their heat competing against each other.

Ishigami breaks off the kiss and continue to carry Kaguya in bridal style "let's get into bed, Shinomiya-senpai" he said while smiling at her

Kaguya's heart skipped a beat upon seeing his bright handsome face, it momentarily snapped her out of her dazed mind full of nothing but sex, her whole face turned red feeling embarrassed after realizing how wild she was being just a few seconds ago, 'it's not her fault that Ishigami is making her this horny, okay?' she thought as she covers her face

Ishigami brought her to the guest room as it's bigger than his own room and it have a big size bed in it even though his room only have a normal one, he sighed 'his parents love showing off too much, the room even have it's own bathroom' he thought to himself, well it all worked out fine he guessed.

He gently laid her on the bed and looked down at her for a few seconds before speaking "Shall we continue where we left off, Shinomiya-senpai" he said while also getting on the bed.

"S-sure" Kaguya bashfully said as she looks up at him, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally, Finally after such a long wait, they'll get to do it once again and unlike the last time, they can go absolutely all out as they have this place all for themselves, this wouldn't end on just one round.

Ishigami slowly rubbed his cock to kaguya's pussy which made her uncontrollably moan harder than she had ever did "Ugh Ishigami, pl-please...just UGH.. put-..it in... ALREADY" she struggling said with pants between each of her words, she's overflowing with lust.

Ishigami on the other hand is thoroughly savoring the sensation of Shinomiya's pussy as he happily listen to her erotic loud moans.

He's so turned on by the fact that he's about to fuck Shinomiya again for the second time around when the president hasn't even done it once, the lust-filled look she's been giving him is irresistibly arousing

He better give it her now

Kaguya groaned loudly as he began slamming his hips towards her, Harder and harder, faster and faster, Ishigami kept on going as his large dick buried inside of her,

He boldly grabbed her small yet erotic chest and begin gently massaging it, it felt way better than he had imagine, it's unworldly soft with her nipples sexually arousing hard, Ishigami quickly leaned down to suck on her breast hungrily which made her bend with extreme pleasure

Kaguya moaned louder and louder as Ishigami continue to fuck her rough while he play with her nipples, every thrust is making her mind numb as she gets overwhelmed by uncontrollable lust that goes through her whole entire body.

"Oh My God, I-Im about to cum Ishigami"

Ishigami stopped playing with her nipples to say something "Hold it for a little bit more senpai, I think I'm gonna cum too, let's do it together" He said as he quicken his pace slamming harder than before

Shinomiya interlocked with his waist again, The feel of his unprotected dick buried deep within her hot, tight pussy as it clung and squeezed his raging hard shaft, was unbelievably good

"HERE IT IS, I'M CUMMING SENPAIIIIIII"

"YES, GIVE IT TO ME ISHIGAM-KUUUNNNN"

They both shouted as they reach their orgasm in unison, Their body's sex compatibility is way high-off the chart as if it's specifically made just for each other.

"FUCK! I'm cumming inside you!!" Ishigami growled and felt Kaguya's legs tighten around him, holding him fully impaled and deep within her

Ishigami's dick began to erupt and load after load shot with force deep into Kaguya's unprotected womb. The hot seed intensified her own already powerful orgasm as load after big load of Ishigami's cum pumped deep into her pussy, filling her up with the hot, potent seed.

Both orgasms seemed to last forever, leaving both in a daze of ecstasy for what seemed like an eternity, until at last, the seemingly-never-ending torrent of cum that Ishigami unloaded into Kaguya's pussy finally came to an end, and her orgasm slowly stopped ripping through her, until both collapsed, lying weakly on the bed and breathing heavily

Kaguya lay on the bed exhausted, breathing heavily, yet extremely satisfied, as Ishigami rolled off her to lie beside her with a big grin on his face. No wonder really, he had just fucked his friend's girlfriend who's also his well-respected senior, he filled her unprotected pussy with his cum twice now too. He have every right to be proud of himself.

"Fuck your pussy is tight, Shinomiya-senpai" Ishigami said breathlessly and Kaguya smiled embarrassed herself.

"That's because your dick is so big" Shinomiya replied bashfully as she rolled back to hide her blushing face, she fell so full as she can still feel his dick inside her, she'll have to take those pills he told her about a few days ago.

"Ah well, we got too in to it that I forgot to teach you about anything" Ishigami smugly said knowing that Shinomiya also probably did, she's the one who started it afterall,

Kaguya twitch as she just now realized that too, her face became even more red and quickly turned to face Ishigami, "I...ah- I still learned something in this so that means it's still counted as practice, right?" She said fidgeting

Ishigami looked at her with surprised because of her sudden cute outburst desperately trying to justify the lust-filled sex she just had with him when she's still have his cum dripping out of her pussy.

Ishigami couldn't resist laughing as he sees her extremely adorable excuse, "you're really cute, senpai. It's making me want to make you mine" he said with seductive tone

"Ah wha-what?... Stop teasing me, when did you become so bold" Shinomiya panickedly said with a completely reddened face, he made her heart skip a beat again, she will really fall for him if she's not careful "you can't do that, Ishigami. Didn't I already told you that I'm dating president"

"I'm just teasing you senpai, you were so cute that I couldn't help it"

"Geez, please don't do that again, okay?"

"Okay but I can't promise" he winked at her which Kaguya just decided to shrug

"anyway, we're not done yet for today, are we?"

"No, since you hasn't teach me the different ways you were talking about yet, right?"

"Yeah, I think this is the perfect timing as we just finished our practice sex, let's go take a shower"
