Ha! Really fun. The pacing is somewhat off and while it could certainly be more explicit, I rather like the goofy, charming take and Diana's increasingly relaxed attitude to being gradually seduced by her tentacled new boy(octopus)friend. It also rather shrewdly uses the mind control instances to sell the idea of while the octopus did physically grope and fondle her all over, winning her over with his multi-tentacled ability to excite her, it also let it off the hook of not being willingly evil or dangerously aggressive on its own, so that Diana can be friendly and flirty with it afterwards.
I am even thinking of making some artwork of my own homaging this scenario. I think Aquaman used to have an octopus friend named TOPO or something like that, and it would be funny if this was his adult or overgrown version.
