I believe Miyuki is imagining Tomoko having sex with her.
I’m very confused by this scene, I honestly can’t tell if Miyuki is imagining this or remembering it. The way Tomoko acts around Miyuki leads me to believe it could have actually happened. But if they actually had sex off-screen, I think Miyuki would be acting differently, so I’m guessing it’s her imagination.
