When Miyuki asks Kei about her meeting with Kaguya, she blushes and says she was too nervous to talk well, with the narrator saying that “siblings tend to have similar tastes,” implying Kei was also attracted to her.
When the MC kisses Hara during the victory celebration, all of the girls get jealous and want one as well, but instead of kissing the MC, they all go to kiss Hara.
The MC watches as all of the girls have lesbian sex with each other for a while, but he eventually joins in as well.
When the group is being interrogated, they question if the MC has “mated” with all of them, to which the girls respond by saying not only with him, but with each other as well.
In the aftermath of the threesome from last chapter, Alia and Dyra flirt with each other, agreeing that they would love to have sex with each other again.
Continued from the last scene, Eri and Takamine go to a karaoke place together.
Takamine then proceeds to undress and have Eri grope and 69 her.
To explain why Takamine is doing all of these things to Eri: Takamine is unsure about how the MC feels about her and how a lot of her advances have gone nowhere. She then does everything she’s done to the MC on Eri, so she can get the full picture. So this is supposed to be a demonstration, not Takamine trying to seduce or have sex with Eri.
The entire time however, in Eri’s thoughts, she keeps wanting to go further and do erotic things like lick her breasts and have sex with her.
Eri then screams about how hard it was for her to resist temptations and that there’s no way the MC didn’t feel the same way.
At the end of the chapter, Eri’s girlfriend found out about the whole thing and proceeds to punish her.
