Rias Gremory texted Mitarai "Come on, don't hesitate, come on up."
Mitarai thought the events of that day were just a dream, but they were indeed real. Therefore, he couldn't refuse her invitation and went to her house, as she indicated in the message.
It was a luxury apartment in Kuoh.
Mitarai confirmed the room number written in the text and rang the intercom, and she came out wearing a thin negligee that seemed to seduce a man.
Since it was Saturday and there was no school today, she was wearing casual clothes. Even if it was casual attire, it shouldn't be a problem, but Mitarai couldn't help but wonder if it was appropriate to dress like that in front of a guy, even though he was her junior. With doubts in his mind, he headed towards the living room.
Perhaps because it was Rias' house, a sweet smell, reminiscent of her body scent, filled the air. Mitarai, who was entering a woman's room for the first time, became stiff with nervousness.
"There's no need to be so nervous. Even if we haven't been intimate, we're still a man and a woman, right? Well, we're not lovers, but it's not really a problem, we could be in the future." She said giving him a side smile.
"Um... why did you call me, senpai?"
"It's obvious, isn't it? Sexual release. I mean, it's only been three days since that day, but you haven't been masturbating alone, have you? ... Well, if that's the case, then it's fine. As for me? I haven't masturbated alone either, and I haven't seen Issei in the last couple of days. Now that I know your dick, seeing Issei will do no good for me."
Mitarai had some weird thoughts about Hyoudou Issei, considering Rias called him not her actual boyfriend.
It was strange that the three perverts who represented Kuoh Academy had become just one person, and it was a strange story in itself that Issei was able to date Rias Gremory, one of the two major elder sisters of the academy.
Even if it was natural for him to be incompatible with the average Mitarai, it was a question of what she liked about him, even if he had a good face but a shitty personality.
"There's something I want to tell you before we engage in any acts. Alright?"
"Uh, well, I don't particularly have any issues with it," Mitarai responded.
"That's good. Well then, without further ado, let me surprise you. I, or rather, we, members of the Occult Research Club, are devils. As evidence, here I'll show you my wings. Something humans don't have, right? I told you this because we devils place importance on contracts. We make contracts for everything we do and respect each other. Since the day I touched your dick, my pussy has been yearning for it. I do have a boyfriend, so I can manage it to some extent, but if I'm going to give up my virginity, I'd prefer a bigger one. So, I want to make a contract with you. What do you say? Do you want it, or not?"
"A devil? Did you just say, devil? And virginity? Indeed, Rias-senpai has glossy jet-black wings on her back." The wings, like those of a nocturnal bat, could be called devil wings as seen in books.
Upon reflecting, Rias did mention that she values contracts.
Mitarai thinking about it "I had knowledge that "when it comes to devils, there are contracts."
Rias had gradually started sharing information, albeit in small doses.
However, that doesn't change anything. What's important to Mitarai is that she is who she is. Even if she were to come out as not human, as long as the woman in front of him is capable of reproducing as a female, there would be no problem, even at the worst. Mitarai had accepted her to that extent.
'When I think about it, she is a woman with an extraordinary beauty. There were various hints.' He thought.
"No, it's not a problem. If it's okay with you, I'll make a contract. Ah, but I would prefer not to stake my life on it."
"That's fine. The contract I want to make is regarding sexual desire handling. Whenever you feel like it, don't hesitate to call me. And if I feel like it, I'll call you too. This contract has no disadvantage for either of us; it's fair. Plus I think you humans have been blessed by gods so I think your powers might awaken anytime if you come into contact with our kind". Says Rias before she added.
"Hmm, it feels like I'm making a contract for the first time in a while. Here, write your name on this paper, please. The contract is established through the soul by means of the name. In this case, since there are no performance conditions, the contract will be terminated when one party claims to want to cancel it and the other party agrees."
Suddenly, a paper appeared in front of Mitarai, and indeed, only the words she spoke were written on it, with nothing strange about it.
I was handed a pen resembling a crow's feather and used it to write my full name. The moment I finished writing, intense pain struck my chest. My heart pounded intensely, and the pain disappeared.
As I wondered what this was, Senpai spoke.
"The pain you just felt is the proof that the contract has been successfully established. The clever devils who thought that no matter how much you write on paper, it wouldn't be felt, improved it. Since then, the number of fulfilled devil contracts has increased. It's true that devils are cunning and self-centered creatures, but they are relatively kind to those they acknowledge. Well, my case is relatively extreme, though."
For the first time, I saw a wry smile on Senpai's face.
Rias Gremory, whom I see at school, is always a smiling woman. That's why she is popular at school, and many people come to her for advice.
"Now that the contract has been established, shall we proceed? And by that, I mean sex, of course. Mitarai I wanna give you my first time, I've been holding back for a long time, you know.
Mitarai, don't think of me as some kind of a shameful woman, yes I dated Issei but I haven't done it with him and I don't plan on spreading my legs for just anyone.
Somehow, it's mysteriously good with you, your aura and everything around you have been driving me crazy since the moment I met you. Plus ever since I saw your thing the other day, my uterus has been throbbing with a desire for it and my pussy won't stop leaking.
Come, this way. It's better to do it in a bedroom with an atmosphere if we're going to do it anyway.
"Huh, what about a shower? Says Mitarai.
"No need for that. We'll sweat when we have sex anyway. Let's hurry my pussy is itching fucking crazy".
