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.

While the MC is having sex with Shieri, Rin and Ann briefly join in by groping Shieri.

While they’re sucking on her breasts, 1 of them mentions how they did this all the time in the past, implying they’ve had lesbian threesomes before.

Eventually Rin and Ann stop to just have lesbian sex with each other in the background.

So I’m gonna tag this as Male Involved, but the MC doesn’t do anything with Rin and Ann after they leave to have lesbian sex.
