Drillia catches Matilda masturbating while watching the MC have sex, so she “helps” her out by seducing and having lesbian sex with her.

During this, we learn that Drillia has had experience in lesbian sex with the princess in the past and through that, became very skilled at touching a woman’s body.

Even though Drilla is a concubine, since this is still behind the MC’s back, I gave this the Cheating tag.

After finding out that the MC had sex with Ui and Uka, they both then invite Mikuru to try it out as well and have lesbian sex together.

Ui and Uka admit to having tried out having sex with each other before.

Saki hesitates to agree, but Mikuru says that she’s interested and says she’ll do it.

Ui, Uka and Mikuru proceed to have a lesbian threesome with each other while Saki watches and masturbates to them, seemingly eager to join as well.

I’m unsure if this will continue into chapter 3, but given Saki’s reaction, it seems likely that it will and that she’ll join.
