At the start of the chapter, Rafalia wants to play a game with all of the characters, so she is able to control them from Chika’s home.
At the start, she freezes Roselia and Nell, causing them to briefly have their breasts pressed together. They then end up in a tribadism position while trying not to let ribbon controlling them fall.
At the end, they get saved by Chika’s mom walking by and tickling Rafalia, distracting her from controlling them.
