In Azusa’s route in the fandisc, Maki joins in while the MC is about to have sex with Azusa and turns the scene into a threesome.
During which, Maki gets curious about girls and repeatedly kisses and gropes Azusa.
Maki then likes kissing girls so much that she says she plans to try it out with other girls later. At first she considers going to kiss Ai, but determines that wouldn’t work out and settles on trying to kiss Renna later instead. Sadly, this threesome scene is the end of the route, so there’s nothing else said about this other than Maki’s plans.
