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.
