Well depending on what you mean by wildest, I'd imagine sex with Aqua would be a lot like fucking a wild animal on the plains of the African Savannah. Verbal communication would quickly break down and she'd devolve into screeching incoherent babbling. There would be a lot of clawing, scratching, and biting as her autism flares up from the overstimulation and she tries to look for an outlet. I also guarantee she'd piss herself. You'd probably be bleeding and covered in her spit, piss, and sweat by the end of it. And then she'd immediately try to go for round two.
I know it's not the "sexy" kind of wild OP had in mind, but it's definitely the most technically accurate scenario.
