Pov Dia,
Inari: "So how was your first night?"
Knowing her, I'm sure she's trying to embarrass us, which works pretty well with Sera.
Dia: "Could you stop asking for information about other people's privacy? We never ask what's going on in your bed with Kurama."
Inari: "Actually, I wanted to know how the spell that Rimuru developed was."
Dia: "We planned to inaugurate the spell during my night with Rimuru."
Rimuru: "I hope my spell will not be uncomfortable for you to wear, Dia-sama."
Dia: "What are you talking about, Rimuru?"
Rimuru: "You would use the futanari spell on me."
Inari: "Is that the name of the spell?"
Dia: "Indeed, I could name the spell that changes a person's gender, but it is too long, so we decided to hold a vote and it ended up being called the futanari spell."
This spell allows us to develop a male genital limb while keeping our appearance and other characteristics. It also allows two women to have a child together.
Dia: "And so Rimuru, you are mistaken. It is not I who will become futa, but you."
Rimuru: "But we said you'd take the front."
Dia: "It's not because I'm the dominant or take the front that I have to be futa. Plus, you've spent so much time believing it, so you should test it first. I don't accept anything else, and that's an order."
Rimuru, although reluctant, had no choice but to accept my decision.
Rimuru: "As you wish, Dia-sama."
The mood had gotten heavy with that little argument, if you can call it that.
Inari: "And so today is the date with Rimuru, right?"
Dia: "Indeed, and Rimuru will also be able to wear her ring proudly, just like Sera."
Rimuru: "It's weird, Dia-sama, but I feel you're implying that I'm jealous of Sera's ring."
Dia: "But that's the case. For a fraction of a second, you felt jealousy, and when I looked at you, you were eyeing Sera's ring."
Rimuru: "But that's not true, I never did that."
Dia: "When you felt jealousy, you silenced your feelings so subconsciously that you didn't realize you were jealous. But I can swear you were. Don't worry, you'll get that ring. I won't let any of my wives go without it. This ring is the ultimate symbol of my love for you."
Author: "I’ll stop there, and we will move on to the next chapter, which is an R-18 with Rimuru."
Reader: "You lazy bastard."
