In itself, regeneration of the virgin membrane is not a difficult act.
As Chihiro recalls, he has heard that it is possible even by ordinary medicine, and it is even easier to restore it by using the healing ability from [Lost Item] such as Aika.
「...When thinking about it like that, it’s a bit weird that my first time doesn’t mean anything...」
「Fufu. Maybe, my sister’s first time is not Master’s, and sister has regenerated her membrane before, right?」
「What!? I’m sure Chihiro-kun is my first!」
After hearing this, Suzu’s eyes insist with all her might that she wants Chihiro to believe her.
However, her eyes were not so clear whether she intended to deceive him or not, still he didn’t intend to doubt her seriously.
Of course, he had no intention to doubt Aika, Maria, Riko, and Hana.
...Anyway, he dared to say honestly that Maria might have broken her membrane once or twice when she pleasuring herself.
「What do you think, Master?」
Yotsuba pulled him back to the topic.
But she looked a little uneasy and continued to speak.
「Of course, I have no complaints about being held by Master. If necessary, I am willing to offer you any place other than my secret part as you like. So...」
Chihiro paused for a few seconds before answering.
Then, he made an effort to smile kindly and told Yotsuba.
「I’m not against it. I’m fine with you regenerating」
「Is it all right?」
Hearing this, Yotsuba still has regrets.
So, Chihiro nodded once, then took a breath and answered.
「...To be honest, I don’t like the idea of Yotsuba and the principal doing this. I don’t want to give the girl who became mine to someone else, even if it’s just a formality」
After all, Chihiro wants to keep his precious things to himself.
He has no interest in letting other people have his woman, which is a little humiliating to say. Even if Yotsuba takes the initiative, he would prefer that they do not mingle with each other.
In addition, Yotsuba’s offer is insane even from a common sense point of view.
To pretend that the child with Chihiro is Principal Ootori’s child――that is the biggest betrayal to his fiancee, Principal Ootori. One might say that "not telling the truth" is at least a kindness...
And from this, there is no doubt that Yotsuba has already lost her mind at an irreversible level.
「Losing your virginity twice is a hard thing to do, but you decided to do it by yourself. For me, for us」
It is natural that Yotsuba who does it is suffering more than Chihiro who only permits it. He can tell by her attitude that she does not really want to do it.
Still, the act with Principal Ootori, and her deflowering, is certainly necessary.
After all, if the two of them dissolve the relationship, Chihiro and his team will lose a part of their advantage over Principal Ootori. Also, depending on the course of the termination, Yotsuba may be disowned by her family as well as Suzu, and Principal Ootori may expel Chihiro and Yotsuba from the school.
Therefore, the risk is less if Principal Ootori and Yotsuba remain in a relationship. To do so, it is better to keep the evidence of Yotsuba’s cheating unclear.
Besides, in order to overturn the situation, Chihiro needed power.
The power to say that even if Principal Ootori is an enemy of Yotsuba, it is okay even if Yotsuba is kicked out of the house.
However, Chihiro does not have such power now.
Then, what in the world can he complain about?
Yotsuba burst into tears as Chihiro tried to show his appreciation.
「Of course, I don’t like what I don’t like. So, I will think of another way until the very last minute」
「Yes. ...In any case, it’s not right now. Even though the membrane will be regenerated as soon as possible, it will most likely not be done until after my graduation」
After all, there is a grace period.
And with this, Yotsuba laughs through her tears and looks at Chihiro with moist eyes.
She then extends her right hand to Chihiro.
But he wonders if she will not mind if he pats her head.
She is older than Chihiro and is essentially an S girl.
When he hesitated to avoid a full-fledged petting and thought so, Yotsuba put her head close to his.
Seeing this, he decided to gently pat her head, which was like a child’s sweetness.
Suzu, seeing such a scene, murmured to me with her eyes narrowed.
「Yotsuba is a bit of a father-con, isn’t she?」
Hearing this, Yotsuba, who is in his arms, is faintly annoyed.
「I don’t want to hear that from sister」
「I don’t really like father that much. Well, I used to like older men, but now I prefer younger men」
Chihiro can only giggle as he is pressed against a breast from the other side.
After all, dealing with these sisters, especially with Yotsuba, who has developed S-ness and aggressive nature, is an unknown territory even for Chihiro.
Since this is the case between the sisters, he can only imagine what would happen if they were to be introduced to Maria and the others.
While feeling the need for further devotion,
「Both of you. You said you had some errands to run」
「Yes, that’s right. I was wondering if Master could hold me and my sister together」
Well, this was almost predictable.
「Okay, but... here?」
Chihiro looks around the quiet student council room.
Although the room has been cleaned up a bit for the school festival, the atmosphere here is basically the same as usual. The arrangement of the desks and chairs, the position of the coffee machine, and so on, is exactly the atmosphere in which Yotsuba and the other members of the student council have spent a long time.
Sunlight shines through the windows, and he can even see people enjoying the school festival.
Still, when he asks mainly to Yotsuba, he gets a nod in the affirmative as if there is no problem.
And noticing that her head is still being stroked, she doesn’t give him an uncomfortable look, rather, she says.
「I don’t mind. Now I am Master’s slave before I am the student council president. Even if Master asks me to take off my clothes in public, it is my duty to obey」
Unlike someone else, she has no taste for that.
Suzu laughs at the added words.
She smiles softly, but with a lustful look in her eyes.
「Even though it feels good. But anyway... I locked the door and closed the curtains. Besides, it’s more exciting to be a little nervous」
「I agree with you」
The two sisters look at Chihiro at the same time, still exchanging a breathy dialogue.
「Come on, Master」
「Let’s play, shall we?」
「...Okay, how can I refuse if you two ask me that much?」
The curtains are closed, blocking the view from outside.
Whether from the outdoors or from other windows, the distance between them is too far away to be of much concern, but just in case, he checks it again.
After that, while the sisters are working excitedly, Chihiro is planning his play.
Since Suzu is there, he thinks it would be better to be more shame-oriented.
