On Pages 54 & 57, Aoi and Midori are briefly shown having lesbian sex in the background while the MC was having sex with Lilliana.

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.
