If the scene starts as fully yuri, but eventually a male comes in and joins them. (The “Male Involved” tag is only used if the male is involved from the beginning 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.
At the start of the chapter, Misao starts seducing and fingering Midori. She then invites her to have a threesome with the MC.
At the end of the chapter, she tells Midori that she’ll keep teaching her stuff if she backs off from the MC, implying they’ll have sex again without the MC.
