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.

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.
The rest of the scene is a threesome.

Emily gropes and starts to have sex with Chika while trying to get her to admit that she’s turned on by the MC.
Chika asks for the MC to help her out, but he gets turned on by the situation and just watches it happen.
After this scene is over, the MC has sex with Emily, so I’ll have this tagged as Male Joins, but he doesn’t interrupt the yuri scene beforehand.

After the MC and FMC save the MC’s childhood friend from getting raped, they go to the FMC’s house. The Childhood Friend wants to be friends with the FMC, and when she agrees, she immediately goes to fondle her breasts and tease her. It quickly proceeds into a threesome.
Childhood friend has some dialogue about knowing a woman’s touch and groping the FMC is her idea of friendship. It could be implied that she has sex or plays with her female friends, but it could also just be a joke, it’s hard to tell.
