If it were any other time, Aqua would have been too shy and reserved to be so forward and would back down at this point. But this was a different time and different state of mind although the overthinking of things was still 100% Aqua. It takes her a moment to think on what to do next to hint at where she was trying to take this. Even if she failed- There was an attempt?

Her hand moves once more, slipping in between them and after some hesitation, starts trailing her fingers against his member. Mostly trying to get a reaction or see if the hint was caught onto.
