The MC walks in on Shinra having lesbian sex with Miyu, but he quickly closes the door to not upset Shinra.
We then briefly hear Miyu’s cries for help and after a short time skip, she runs out of the room partially nude.
There’s a 12 Second Clip that’s only available in the DVD version of the series that shows a little bit of what Shinra does to her.

Beni is shown sensually washing Shinra’s body in the bath.
Beni’s hand seems to go pretty low while Shinra is says her name with a blush. And given Shinra’s personality, there’s some implications that they might be doing a little more with each other.

While the group is talking about Miku, they talk about how stats skyrocketed when she came into contact with AST and peaked when she met Origami.
Another person brings up that she hosts concerts only for women and that there’s rumors she brings some of her fans back home, implying she was sleeping with them.
As far as I’m aware, there’s never been confirmation in the anime or light novel for if Miku actually had sex with those girls. But after her scenes with the “gender bent” MC before she realized he was a guy, it’s strongly implied she at least did some erotic things with those other girls off-screen.
