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.
Emily tells the MC: “I won’t let you have sex with Chika until you say you love her.”
When Emily realizes that it’s not enough motivation for him, she starts to have lesbian sex with Chika while pretending to NTR the MC as a way to provoke him.
Chika immediately realizes what Emily is trying to do, so she plays along with the NTR teasing, which eventually results in the MC stepping in.
After Saki’s mom finishes having sex with the MC, she has sex with Saki as punishment for hiding her relationship from her. Saki gets very turned on from having sex with her own mother.
Eventually the MC rejoins them and it remains a threesome for the rest of the chapter.
Saki’s mother is married, but there’s no “Cheating” tag because she got permission from her husband to have sex with them.
