Those girls actually piss me off. Iris' wings are still damaged, and that needs to be looked into and treated if necessary. For some reason, that damage doesn't seem to have manifested in her human form. Not to mention that this is Iris' very first time transforming and any number of things could have gone wrong. But of course, "Kyaaaa~ Protagonist-san is being ecchi sketchy one-touchy." Being overly puritanical is just inviting trouble guys.
