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
Tracy seduces and has lesbian sex with Seung-Ah, telling her that while they swapped bodies, she masturbated to find out all of her weak/pleasure points.
Near the end of the chapter, Sejeong (who has swapped bodies with the MC) joins them.
Since it’s still the MC’s body, I’ll tag this as Male Joins.
This continues into the next chapter, but I counted it as a new scene since Seung-Ah went to go join the MC in Sejeong’s body.
