I said this on the other site, but I feel it's worth repeating: this story is just awful.
The whole "hey Rose, get nekkid in public" thing was kind of cute at the clothing-optional beach where no one knew them and they were essentially by themselves. However, putting her on the spot here? With people Sophie actually does know? That is a "power move" of the worst kind. I'm very disappointed that Funkybun took their story this way. Just because Rose eventually gets into it doesn't mean it's okay for Sophie to keep doing this to her. Sophie is a bad, abusive person who gets off on making Rose uncomfortable, and Rose deserves much better.
Also, the repetitive nervous internal dialogue is grating. Yes, fine. Rose is there. She's nervous and awkward. Sophie put on their private skin flic against her poorly-spoken wishes, people whom she doesn't know are watching, and she's popping a nervous boner and masturbating from the indirect attention. Great. I don't need to know her every thought in every panel.
