for Advance Chapter
"Hey, Amane, do you want to have a Christmas party at your house?"
"No."
Chitose mentioned this after school. Christmas is not an event that Amane has much to do with, but Chitose and Itsuki seem to want to spend it with Amane.
"Eh, why?! You're probably alone anyway. Ah, maybe you've got a girlfriend?"
"No, when you two are together you just flirt with each other without paying any attention to me. Do it somewhere else I'm not around."
As expected, both Itsuki and Chitose keep it to themselves at school, but when they're outside or when they come to Amane's house to play, they start kissing and flirting without caring about what other people think.
My body can't handle being with a stupid couple all day.
"Why don't you join us, Amane? As I said before, Amane is more than welcome."
"They don't mix. What kind of couple are you guys really..."
"Well, if you don't like it, that can't be helped, Chitose. Ah, but it's a shame."
"Sniff sniff"
"You guys..."
The two of them pretend to cry. Even though they're like this, they're one of the few friends who are friendly with Amane. Maybe it's not good to treat them so carelessly.
The thought of Mahiru comes to mind. I don't know what they'll say if I run into them.
Should I tell them not to come to the house while we're there?
"Okay, but only until the evening. And if you get too flirty, I'll kick you out."
"Yay, I love you Amane."
"I love you!"
"Ugh, that's gross, don't stick to me!"
So that's how my Christmas plans were decided.
"Christmas? I don't have anything special to do."
After returning home, I asked Mahiru about Itsuki and the others, and it seemed that Mahiru was spending Christmas alone. Mahiru has many friends, but they all seem to be spending Christmas with their own partners.
"I bet you get a lot of invitations from guys too? I heard you're knocking them down here and there."
"It's not like I'm trying to sink you or anything... I wonder why everyone wants to spend time with someone like me."
"Well, it's Christmas after all. Maybe they're hoping to do something naughty?"
"It's impure."
…, …, ….
"Well, is that what Mahiru is saying?"
"...I'm also a little embarrassed about myself."
Mahiru was so curious about erotic things, and even discovered the joy of exhibitionism, so how could he call her impure?
"But, I still can't understand why someone would want to become intimate with someone they don't know well just for the sake of their body."
"You can tell if the purpose is erotic or not, right?"
"Yes, but... there are people like Amane-kun who don't give in to their naughty and perverted habits."
"So why did you bring me up?"
However, this means that Mahiru will be alone on Christmas. I take a quick peek at Mahiru's face.
It's not that she looked particularly lonely, but I felt bad about leaving her like that.
"Oh, if that's okay."
"yes?"
"I can't make Christmas Eve, but do you want to spend Christmas together?"
I'm not used to making such invitations again and it's starting to feel embarrassing.
Inviting a woman to Christmas can't help but seem like you have ulterior motives.
Surprisingly, Mahiru was quick to go along with Amane's proposal.
"Yes, yes. That's fine."
But even though I invited you, I'm not sure what to do to pass the time.
"Oh sorry, I haven't thought of anything in particular. Is there anything you want to do, Mahiru?"
"I agree"
Mahiru looks around the room restlessly and points at anything that catches her eye.
"That's what I want to try."
At the tip of his fingers was a game console. He didn't play much alone, but there were quite a few party games lying around for Itsuki and the others to play when they came over.
"A game? Is that okay?"
"...Yes, I've never done it before, so I'd like to try it."
It was unexpected, but if Mahiru wanted to do it, it wouldn't be a problem. In any case, the two of them couldn't go out together, so there was only so much they could do.
"Well, I guess it's okay to just take it easy every once in a while."
"yes"
Sensing a hint of sexiness in Mahiru's small smile, Amane couldn't help but look away.
"Merry Christmas!"
"Yes, yes, Merry Christmas."
"Come on, it's no fun if we go around like this! Let's liven things up a bit."
"I'm still trying my best, so please spare me."
And then Christmas Eve arrived. Pizza and juice were lined up in Amane's room, and he was fully prepared, but it seemed impossible for him to keep up with the excited couple.
"Well well, this is getting Amane excited too. Let's have fun and not worry about it too, Chitose."
"Yes."
Itsuki and Chitose were in high spirits, and Amane was at their mercy. This was the usual scene.
Along the way, the observant Chitose shouted, "I smell a woman!", but they managed to brush it off somehow.
"Hmm, there's something fishy about you, Amane. I get the feeling you're hiding something."
"I'm not hiding anything. What is your basis for that?"
"Woman's intuition!"
Women's intuition is scary. Almost everything Chitose pointed out had to do with Mahiru.
Even though the evidence was supposed to have been destroyed beforehand, this makes me nervous as I don't know when the truth will come out.
"But, I thought that Amane had finally found a girlfriend, so it's a shame. It's good to have a girlfriend, isn't it Ikku? Mm-m-m."
"That's right, chhi. Slurp, slurp."
As he had feared, the two of them started flirting with each other, regardless of Amane's presence.
"Hey, I told you I'd kick you out if you started flirting. You two can do that kind of thing when you get back."
"Huh? That's fine. Amane, you masturbate all the time when you're alone, right? Then you can masturbate while watching us. Or do you want to join in?"
"Masturbation and sex are two different things. Just stop."
For Amane, who keeps interactions with others to a minimum, masturbation alone and sex as an act to confirm love are two different things.
"Tch, there's no other way. I'll leave it here for Amane's sake――Ah, Ikku, look!"
Chitose pointed outside, where white snow had begun to fall lightly.
"It's snow! It's snow, Ikku!"
"It's a white Christmas, let's come and see it together, Amane."
"Yes, yes."
Although it wasn't enough to get excited about, it was rare for it to rain on Christmas. Amane also headed out to the balcony.
"Huh!?"
Chitose, who had already been on the balcony, called out. At that moment, I had a bad feeling.
(It tastes bad!)
Rushing to the balcony in a panic, Chitose saw Mahiru right in front of her.Naked...
"Ah, the girl next door to Amane is an angel?! By the way, why is she naked?!"
"Hmm, I see."
Mahiru, fully clothed, cowers next to Amane.
At this point, there was no way I could hide it any longer, and I was forced to tell him everything about my relationship with Mahiru.
Of course, that includes all the erotic stuff up until now.
"...I'm truly sorry."
"That's why I told you not to expose yourself alone."
"Well... I can't stand the thought of being alone today... and besides, I haven't been outside."
It's true that there's a fine line between whether a balcony is considered outside or inside the house, but that's not what I'm talking about here.
"Well, I understand. We won't spread rumors or anything, and we don't think it's strange, so don't worry."
It seemed like Itsuki was planning to wrap things up with this for now. It was good that things were quick and easy in these situations.
"Hey, hey, Angel! Do you like sex too, Angel?"
"C-Could you please stop calling me angel...? Um, as for the naughty stuff, well..."
Leaving aside Amane and Chitose, who is also her gender, Mahiru's embarrassment seems to get the better of her in front of Itsuki, who she just met. Chitose's momentum also makes Mahiru hesitate.
However, Chitose seemed to take the fact that she didn't firmly deny it as a positive thing.
"Well then. Let's all have a group sex orgy! I've always wanted to do this, but I almost gave up because Amane didn't get a girlfriend."
"R-ran?"
"Calm down now, Chitose. Shiina is pulling away."
I chopped Chitose on the head. Chitose glared at me in agony with teary eyes, but I ignored her.
"I told you before that she's not my girlfriend. And even if I did have a girlfriend, I told you before that I wouldn't have orgies or anything like that."
"Boo. Amane's stingy."
"Besides, let alone sex, I've never even laid a finger on Shiina."
"Eh?! But you're doing all sorts of naughty things?!"
He had carried her on his back when Mahiru twisted her ankle, and he had touched her through a vibrator and an onahole, but their skin had never come into direct contact.
Somehow, I felt like that was a line that shouldn't be crossed.
"Well, on the contrary, Amane's self-control in not making a move even after going that far is impressive. Don't you think you'll end up losing your patience?"
"What?
"You were really hesitant just now." I remembered one time I tried to say it didn't exist and ended up going out of control.
Even without that, it was becoming difficult for Amane to bear a sexy, cute, beautiful girl like Mahiru recently discovering her love of exhibitionism and showing off her naked body.
"What a waste! Shiina-san, sex feels so good. If it's with someone I love, I want to have sex all night and melt into each other!"
"A-a whole meal... we melt into a mush..."
What Amane and Mahiru had done up until now had been an extension of masturbation, albeit a slight deviation.
With the new concept of sex planted in her mind, Mahiru's head seemed on the verge of exploding. "Well, I'm sure Shiina-san would be in a difficult position if we suddenly asked her to have sex. So, I think it would be best if she watched us have sex first."
"Huh?"
Itsuki suggested this in the same light-hearted tone he always used to tell Amane. Even though Mahiru was there, he wasn't intimidated at all, which was typical of Itsuki.
"That's great! If Shiina-san sees Ikkun and I having lovey-dovey sex, she'll want to have sex too!"
"You know what, you guys, stop messing around like this..."
As expected, Amane tried to stop her, but his sleeve got caught and he felt something pull him. When he turned around, he saw Mahiru with her cheeks flushed and looking down.
"Um... I'd like to see it."
When Chitose heard this, her face lit up and she jumped at the opportunity.
"Yes, yes, she's a high school girl of that age, so I'm sure there's a lot of interest! I'd be more than happy to meet her!"
"Seriously..."
The story progresses smoothly, leaving Amane, the head of the household, out of the way. It seems impossible to stop it.
"If that's decided... Ikku, kiss me."
"Yes, yes, mmm, kiss."
"Wow..."
For Amane, this was an everyday occurrence, but for Mahiru, it was probably the first time she had seen someone she knew kissing in front of her. She stared at him with shining eyes.
"Mmm, kiss, haa, Ikkun, Ikkun, I love you..."
"Slurp, slurp, hah, mmm, I love you too, Chitose."
They continue kissing, whispering sweet nothings to each other. Eventually, it gradually escalates and turns into a passionate kiss with their tongues entangled.
"Mmm, lick, slurp, mmm, aahh, ahh, smooch."
"Hmm, mmm... can I touch you?"
Without waiting for a response, he begins to fondle Chitose's breasts over her clothes. Chitose reacts by slightly twitching, but doesn't seem to mind at all and just lets him do what he wants.
"Ahh, hmm, that feels good, Ikku... right, touch me directly?"
He takes his hands on her chest and guides them under her clothes. Meanwhile, her jacket is being removed and the buttons on her shirt are being undone one by one. "Ahh, even though Amane and Shiina are here, they're still seeing my boobs."
"It's okay, it's cute, Chitose."
Then her shirt was removed, revealing her pink bra, which was then pulled up rather roughly, exposing Chitose's breasts.
"Chitose's breasts are cute, aren't they? They fit perfectly in my hand and are incredibly sensitive."
"Ahh, Ikku, don't be so forceful!"
Itsuki holds Chitose close and squeezes her breasts, showing them to Amane and Mahiru. Even when he says something like that, I don't know how to react.
"sensitivity..."
Mahiru seemed to have something on her mind, and was lost in thought as she looked at Chitose and her own chest
"Ah, Iku-kun, I'm getting turned on by being watched, I can't help it... Ah, I'm going to cum just from your boobs!"
"Okay, let's let you two watch me come."
Itsuki pinched Chitose's nipples hard. At that moment, Chitose's body jumped up.
"Ahh, hmmm, yaaaaah!!"
She climaxes violently and collapses, leaning against the tree.
"It was cute, Chitose. You two think so too, right?"
"Y-Yes. It was very charming."
"It's not just cute, it's sexy."
"Fujimiya-san..."
I was glared at in the middle of the day, but since we were doing something erotic, it was inevitable that she would have that impression.
"Haa, haa... Hey Ikkun. I, I've already..."
"That's right. When I see how cute you are, I can't help but get undressed. I'll take my clothes off too."
He lowered her skirt and reached for her panties, and finally Chitose was left in her birthday suit.
"Ahh, I'm showing my pussy to someone other than Iku-kun..."
Chitose's pussy was open a little wider than Mahiru's, and it was twitching a little, probably because she had just climaxed.
"I-I wonder if mine is like this too..."
Mahiru was muttering that she couldn't see her own things.
"Well then, let's go, Chitose."
Itsuki also took his penis out of his trousers and put on a condom. As expected, he seemed to be using good birth control.
"Yeah, come on... Ikku."
Itsuki's thing slid into Chitose's pussy. It fit so deep it was strange that it even fit inside Chitose's small belly.
"Mm! Ah, mmm..."
"W-W-W-Chitose-san, are you okay?"
Even though I knew that was how it was, it was still a pretty grotesque act to witness in real life. And yet, Chitose was making sounds that seemed to be enjoying it.
"Mmhh, ah, uh, yeah. It hurt the first time, but ah, now it just feels good."
"We've done it so many times now that your vagina has taken on my shape. It feels great, Chitose."
Itsuki gradually moves his hips, thrusting in and out as if stirring inside her vagina. The lewd squelching sounds and the smell of sex fill the room.
"Ah, ah! It's going in and out, can you see Ikkun's penis going in and out?!"
"Y-yes, I can see it. It's so...naughty."
Mahiru was absorbed in the sight and atmosphere and seemed to be excited. Her hands were already reaching for her crotch, fidgeting.
"Ahh, ahh, it feels good, I'm cumming, I'm cumming! I'm about to cum! Kiss me, I'm cumming!"
"Oh, I'm about to come too! Let's come together! Slurp, slurp... let's slurp, mmm, haa."
The piston movements speed up as they approach the final spurt. The sound of skin slapping against skin echoes around the room, and love juices splash from where they are joined.
"Slurp, mm, puah! Ah ah ah ah! It feels good! I'm coming! I'm coming... aaaaaah!!"
"Ugh... I'm cumming!"
At the same time that Chitose climaxed, Itsuki also ejaculated inside her vagina. After her body trembled several times, Itsuki's penis slid out of Chitose's vagina.
"Haa, haa, you came a lot today too, Ikku."
"Yeah, that was awesome. I love you, Chi."
We finally exchanged a light kiss. Both of us looked very happy.
"So, how was our sex?"
Afterwards, I did my best to stop Itsuki and the others who were calmly about to start the second round, and after I had cleaned up the room and finally calmed down, Chitose asked me.
"Well, well... it was wonderful to see that you two loved each other so much."
"Right? Right! Sex with someone you love is so happy and feels so good! Shiina-san, if you try it once, you'll be hooked, I'm sure."
"B-But, Fujimiya-san and I aren't in love with each other or anything..."
"Huh? I didn't say anything about Amane though."
"H! Chitose-san!"
The two girls were squealing and making a fuss. Now Mahiru seems like a normal high school girl.
"Look, we've finished cleaning up and it's almost time for you two to go home. You'll continue when you get home, right?"
"Of course. I had decided from the beginning that I would try having sex all night with Chitose today."
They're still the same lovey-dovey couple. If I leave them alone, they might start making out again here.
"Well, we're going home now, but Amane, be nice to Shiina-san, and do lots of things."
"Amanet up, you're meddling. Get out of here."
I leave Chitose, who keeps teasing me, in Itsuki's care and kick her out of the house. Even though it's Christmas Eve, I'm exhausted
"Sorry, Mayu. I got caught up in that noisy guy."
"No, I was a bit confused by how lively it was, but I had fun. And... it was a learning experience for me." Her face turns red. It goes without saying what she was studying.
"Well, that's fine. By the way, you've been sitting there for a while now. Is that okay?"
"N-no... it was a bit of a stimulating sight, so my legs gave out... I'll stand up now... kyaa!?"
"It's dangerous."
Mahiru tries to stand up but loses her balance. I quickly grab her hand and pull her towards me.
"Phew, are you okay?"
"S-sorry. It's alright."
Mahiru looked up and our eyes met. Because I'd pulled her too tightly, her face was just a few dozen centimeters away.
Our breaths collide.
When I touched Mahiru's hand for the first time, I could feel the heat.
I'll bite into the lips in front of me, push her down, tear off her clothes, lick every inch of her body, and paint her vagina and the outside with my own color with my cock.
"Huh?! Sorry, I pulled too hard."
He suppresses the desire welling up within him and quickly distances himself from Mahiru.
"......home"
"Well, it's too late now, so let's enjoy Christmas again tomorrow." He somehow manages to cover up and return Mahiru to her room. If he stays with her like this, he might lose his mind and attack her.
"...I understand. I'll be heading home now."
I arrived to my room without any luggage anyway, so I just headed straight for the front door.
"...You wimp, Amane-kun."
I decided to just assume that what Mahiru said at the end was just my imagination.
