After the MC reveals to the girls that he saw them having sex in the previous scene, they kidnap him and tie him up.

He then blackmails them saying he’ll keep their relationship a secret if he can watch them have lesbian sex with each other.

They reluctantly agree and allow him to watch and masturbate to them having sex.

This continues into the next scene.

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.
