They lay their bodies on the big bed.
Chihiro is on the bottom, supporting Aika's weight, and they kiss deeply again. They kiss each other deeply, even though their mouths are sticky with each other's saliva.
Apparently, Aika loves to kiss.
But she is not reluctant to caress, serve, or have sex. On the contrary, she sometimes asks for it herself, though on the other hand, she tends to be satisfied with plenty of kisses even if other things are neglected.
Chihiro once asked her the reason for this.
『Hmm...because kissing is equal, maybe』
There are unavoidable differences between men and women when it comes to breasts and genitals, but not when it comes to mouth and tongue.
Aika said that she likes kissing because it allows her to love and desire the other person in the same way regardless of gender.
Chihiro thinks that this is a typical thinking of Aika, who is concerned with the equality of lovers.
Therefore, he respects Aika's feelings as much as possible.
And once again, they continue kissing and caressing over their clothes.
When their lips meet and their tongues intertwine, Aika feels much more. Aika's expression became more and more debauched even when caressed through her clothes, and she started to demand for Chihiro.
They kiss again and then take off each other's clothes and hug each other in their underwear.
As Aika's navel is exposed, there is a mark engraved on it. The reason Aika has the mark is because she saw Riko and the others are having so and it's not fair.
『Chihiro-kun. Can I have that, too?』
『Eh? Takatsuki-san... is it okay if it matches with others?』
『Umm. Can you just change the design?』
Chihiro thought that was absurd, but he gave it a try, and to his surprise, it worked.
It is the same mark with many overlapping characters, but it looks like a different design because of the difference in the way the characters are combined.
In Maria's opinion, this is a result of either Chihiro's ability to change the design according to his image, or the subject's mind, who receives the mark.
「How is your condition since you got that?」
「Yes. I feel really good. The healing process seems to be a little more efficient」
「Oh, that's good」
Since Chihiro is relieved, he will explain the effect on the assessment as well.
When he asked her again if she wanted to remove the mark, Aika shook her head, just like Riko did.
「I guess I'm the same as Riko-chan. If I leave it in forever, it won't be cheating」
This indirectly means that 「she has no intention to break up with Chihiro」.
As for Chihiro, he was rather happy about that and smiled.
Then, Aika's arm tightened.
「More importantly... kiss me more」
Chihiro doesn't know how many times they've kissed each other today.
But, speaking of kissing, there's something else Aika has been telling him.
『Chihiro-kun. Please try not to kiss me at school』
『Okay, but why?』
『Because it's a problem if we'll be in the mood, right?』
Well, if they kiss each other as foreplay every time, their bodies will be conditioned to do so.
So, when they kiss in a crowded place, if they put their tongues in reflexively, it might soak their underwear... and that would be embarrassing.
Of course, Chihiro agreed to this.
Chihiro doesn't mind if asked, but there is no need to show it. People already know enough about Chihiro and the others.
That said, he doesn't hold back in this apartment.
As long as only Maria, Riko and Hana, who see it, it's no big deal. In fact, Chihiro wants to show off his love for Aika to them.
Besides, Maria and the others, especially Riko, are more excited than usual because of this atmosphere, which makes him happy.
When Chihiro crawls his fingers into Aika's peach-colored panties, a small sound of water is heard.
Well, his actions with Aika are gradual because he's not 「training」 her, but still, her body is developing little by little.
And it made her more and more excited and wet.
（...One day, I want to make her come with just a kiss）
While Chihiro carefully caressed her private parts with such thoughts, Aika stopped kissing and whispered to Chihiro.
「Chihiro, I've already...」
Nod! Chihiro nodded his head and separated from her.
Then, Aika, who was sitting on his stomach, looking down at him, and Chihiro softly asked her.
「Aika, could you do it with your mouth?」
Aika replied honestly and moved her body to position herself between Chihiro's legs.
She unbuckled the belt of his pants, then the hooks, and unzipped it. When she was done, she put her hand on his pants and slowly pulled it down.
『It'll get in the way when I'll do it later...』
Since the second time she gave Chihiro a blowjob, she had started to remove Chihiro's pants and underwear completely, saying something like that.
By the way, in this case, she meant sex in the normal position.
She said that she was bothered by the clothes hitting her legs when Chihiro thrust into her.
（...I'm grateful for this kind of detail, because it's hard for me to notice. Especially for Maria and Riko, because of their position as slaves, they often tend to accept it or ignore it even if they notice it）
「Then, I'll do it, okay?」
Aika holds the base while lightly stroking it, and runs her tongue over the tip.
Just a light stroke of her tongue made Chihiro's body jump.
『Chihiro, aren't you favoring her just because she's Takatsuki-san?』
Riko once pointed out to him like that, but he can't help reacting when Aika gives him a blowjob.
It is not about the technique, but simply the fact that his girlfriend does that to him that makes him happy.
「It seems you've gotten used to it」
Aika's movements are still crude, but she does her best to move her tongue.
She licks it like it's an ice cream or something, and thrusts the tip in and out of her mouth. She touches her tongue to the base and licks up to the tip.
『Takatsuki-san. Chihiro will feel better if you lick more boldly』
『E-Even if you say so...! I'm...』
Aika shouted when Riko pointed it out to her, but she listened to the suggestion without hesitation. Little by little, Chihiro could see that she was trying her best to become better in her own way.
And gradually, as she worked hard to improve her skills, Chihiro's arousal began to increase.
「Aika, I'll put it out」
Chihiro call out a little earlier, and Aika reacts with a twitch.
With both hands, she placed her fingers at the base of the penis and sucked it into her mouth, waiting for ejaculation. His rod was a little sore from the unconscious force of her fingers. Still—
Spurt! Spurttt! Spurttttt!
Aika is startled by the force of the ejaculation and catches about half of the white liquid with her face.
She coughed up half of what she had caught in her mouth, and did not seem to be able to swallow it well.
Still, when she swallowed a small amount, she said with tears in her eyes.
「Don't worry about it」
Even though Chihiro smiled and told her, Aika's face remained blank.
Well, it is inevitable that she is not good at putting foreign things in her mouth. But it seems that she's upset because of her rivalry with Riko and the others.
（I wonder if there's a good solution...）
Chihiro thought about it for a while and suddenly came up with an idea.
「Aika, can you come here for a minute?」
Chihiro beckoned to Aika, who still had semen on her face, and gently kissed her face.
Kiss… Lick… Slurp…
He slurps up the fluid and puts it in her mouth.
（I had kissed Riko and Maria after their blowjobs, but this is the first time I had licked my own semen）
Perhaps it was because this is his own semen, but it smelled even fishier than Chihiro had imagined.
Really? Everyone is drinking this stuff for me?
When he thought about it, he felt grateful.
With a mouth full of semen, he hugged Aika's surprised body.
He then kissed her half-heartedly.
For a moment, Aika tried to resist, but when he hugged her gently, she quieted down. She opened her mouth to accept Chihiro's tongue, saliva, and semen.
The moment her tongue touched the semen, her body trembled lightly.
But that is the only clear change. When the semen is mixed with each other's saliva, Aika swallowed it little by little.
After the first few throbs, all the semen is gone from both of their mouths.
「You did good」
He patted her head but got an annoyed glare.
「Don't put that in your mouth. What if you get sick?」
What will happen to Aika and the others?
Chihiro wondered, and when he said it out loud, she turned her head away.
What's the logic behind that?
Chihiro is puzzled, but Aika quickly turned her face back to him and smiled.
「...I'm kidding. I'm sorry, thank you. I'm happy」
Then she takes off her underwear.
Soon her bra and panties are removed, exposing Aika's naked body.
Well, the bush between her legs that had been bothering her has been trimmed and is now hairless.
But because of embarrassment, she didn't let Chihiro help her shave it off, and she did it in her dormitory.
『It's a little embarrassing... when I take a bath with my friends, but...』
He also remembers how he couldn't help but hug her when she smiled with lightly dyed cheeks at that time.
Aika pulled Chihiro's hand away and let him sit up, and then laid down and opened her legs instead.
Chihiro nodded and took out a condom from the cabinet in the bedroom. He tore open the package and put the rubber on his penis.
They had been using contraception with Aika since the first time, just in case.
After all, the way of taking “responsibility” between Maria and her slaves and Aika, her lover, would be different. If at this age they have a baby or get married, both of them will be in trouble in terms of their future career.
Back to the story, Chihiro put his hands on Aika's legs.
As he placed his penis on her wet clit, Chihiro gently pushed himself down.
The tightness in her vagina remained the same.
However, the expression on Aika's face is almost completely devoid of pain.
She had grown accustomed to having Chihiro inside her, and had begun to learn to take pleasure in it.
「I'll go slowly, okay?」
After slowly inserting it to the base, he slowly pulls back in the opposite direction.
Stop for a moment at the line where the tip can barely be pulled out, and insert it again. Repeat the process with a monotonous rhythm.
For the pleasure that leads to climax, it is important to use intense stimulation and then slow and steady movements.
However, these are for people who are used to it.
For Aika, who is still developing, it is better to anticipate and wait for the next pleasure.
In addition, it would be easier to open up her sexual senses if he caresses her nipples and clitoris at the same time, but since this is an opportunity, Chihiro is trying out various methods.
While Aika is breathing and concentrating on the feeling of the penis, Chihiro is trying his best to keep it constant and keep pistoning.
As he rubs the flesh of her vagina against his tightly clenched cock, the desire to ejaculate increases, but he holds back.
Aika's breathing starts to become uneven.
The feeling of the penis thrusting in and out of her vagina was gradually turning into a pleasant sensation.
So, Chihiro increased his pace a little.
A clear sweet voice began to rise.
At this point, even Aika could easily feel the strong stimulation.
Pound! Pound! Pound!
Chihiro accelerates the rhythm and slams his hips harder. But his movements are still constant.
Aika's shy panting is very adorable.
Aika's mouth is half open, and she is shaking her face from side to side with sweat on her forehead. It seems that her pleasure is starting to reach an uncontrollable line.
Chihiro looked down at her and continued to poun his hips.
「Chihiro, you...I, already...」
「Do you want to cum?」
「U-Unn... I'm cumming... I'm cummming!」
Aika's body jumps, and she hugs herself.
Her mouth opens wide and she lets out all the air in her belly, then lowers her body to the bed as she inhales.
As she climaxed, the pressure of her tightly clenched vagina caused Chihiro to release his semen into the condom.
Spurt! Spurttt! Spurttttt!
Aika, who was breathing heavily, lifted her hands and covered her face with her arms.
It seems she is still embarrassed to show her climax in public.
「You are so cute, Aika」
Therefore, Chihiro avoided saying too much and just said a few words to her.
However, perhaps she was still embarrassed, Aika's body trembled a little.
Chihiro smiled and replied softly to the mumbled words while Aika covered her face.
