Yeah, here we go!
I would also consider injecting some in her fillet. Like with boys, it looks much better when it is aroused due to blood circulation. She could be brought to an near-edge, then stopped and little injected to keep that. The places where and how could depend on how it looks like - they differ but all are beautiful :*

But that's only idea. Doing it casual would be also great, just keep the story going :D
