The group gets stuck in a dungeon room where the only way out is for 2 people in the room to have sex with each other.
Much to Nabo’s disappointment, who thinks he’ll get to have sex with one of the girls, Sera jumps on top of Lunaar and they have lesbian sex with each other instead.
At the start of the chapter, Malida began to have sex with the MC, Irena and Lichere a lot more off-screen as her bloodlust for the upcoming battle also increased her arousal. (This is very inconsequential, so I didn’t tag for this part, I just wanted to mention it.)
After the battle, we are introduced to Liese, which upon finding out she’s basically a tomboy, we get these lines from Malida:
“Albert, a girl, who crossdressed as a guy, might be nice as well. I like girls, but women like Liese are my guilty pleasure. She gets me all riled up. I think it’d be nice to get a taste of her.”
Malida then drags Liese off to the bedroom where they have lesbian sex with each other several times off-screen, but we do hear them moaning.
Eventually, Irena and Lichere join them as well and there’s a short yuri foursome while the MC watches.
This is also the first time any of the girls kiss each other on-screen. It’s possible it has happened off-screen before, but it’s never mentioned.
After a while, the MC joins and remains involved for the rest of the scene
After the MC is saved by Malida and reunites with Lichere, she is in a revealing maid outfit because of Malida’s tastes.
Malida then immediately sits next to Lichere and begins to grope and lick her body while talking with the MC.
A lot of their conversation stems towards Malida’s sexual history and preference towards women, but the MC being the exception.
The scene then proceeds into a threesome between them.
Afterwards, Malida and the MC talks about the future of their relationship, to which Malida makes a request:
“I told you that I love women, right? My body has been changed so that it won’t adapt to any male other than you, Albert, but I still wish to be served upon by plenty of pretty girls. That’s why I’d like you to allow me to have lovely girls as lovers!”
The MC agrees to those conditions when Malida says that she would also wish to share her harem with him.
Rachnera punishes and interrogates Lilith by subjugating her to BDSM with her webs.
Most of this is off-screen and it’s very implied that they have sex given that they’re both nude, but it’s never really answered if they do, even in the manga.
This scene is in Chapter 21 of the manga. Lilith also shows up in Chapter 40 purely to see Rachnera again.
