The scene features a girl rubbing her body against another girl.
This tag is not to be confused with Grinding, as that tag is used for things like dry humping.

The part starts with Mio, Yuki, Kurumi, Maria and Noel all taking a bath together.
Noel begins by helping wash Mio, but due to her contract, she immediately starts to moan when Noel touches her. Noel playfully teases her about it and then continues to wash every part of her body, which causes Mio to keep moaning, so she tries to think about how Basara’s touch is better.
Later, Yuki asks Mio to wash her back, so Mio playfully dumps water on her, prompting Yuki to jump and straddle her while beginning to grope her breasts. Since Mio didn’t want to be outdone, she gropes Yuki’s ass in retaliation, as that’s her erogenous zone.
While Yuki and Mio are grope-fighting each other, Maria goes to tease Kurumi at the same time. Maria starts to grope her breasts and lick her neck, saying she’s just as shy as the first time, despite them doing this many times together off-screen.
I’m putting the Implied Sex and Off-Screen tags for Maria’s dialogue about having fun with Kurumi.
