In the last decade or so, there has been a little bit of an increase in the awareness of our fetish. Searches on various mainstream porn and sites result in a spattering (pardon the pun) of messy videos but it is easy to see that most of these videos star models just trying to make a buck who stumbled upon a messy producer.
A lot of the models seen in the videos featured in messy fetish sites DO seem to enjoy getting messy but even on some feature sites, it's obvious that so many are just working another gig.
(Disclaimer: I said on "some" sites. I know that a lot of you girls truly enjoy your work!)
I'm rambling. What I'm getting at is... more important to me than the coverage, more important the substance(s), even more important than how attractive I find the people getting messy, is whether or not it looks like they are truly having fun. It is such a huge turn on for me to see a woman letting go of concern and giving in to having fun and appreciating how good it feels to get messy.
I attached one example. It's not the best example of what I'm talking about but I stumbled upon it today and it mused me to start this thread.

So what is YOUR favorite pic of someone looking like they are genuinely having a blast sploshing?

I don't have any pics, but I agree 110%. I know there's a lot of people in the adult industry who are doing it solely as a job, and that bothers me in a couple of ways. If someone is truly having fun that will come out in the pics and videos and that makes that video, and that person, a hundred times more attractive to me.
If you think about it, this interest (like many) is kinda silly. I don't know why I like it, but I do. I already feel a little guilty about indulging, so if my partner is "*sigh* Ok, i'll tolerate it" and doesn't have any fun at all, that makes it even worse (in addition to the level that I asked someone to do something they really don't like.) (Of course, yes, it's also my job to try to make it fun for her.) It should be fun, and funny - have fun with it. My fiancee doesn't have the same interest in it that I do (it doesn't turn her on), but it turns me on, and that turns her on - plus usually she sees the 'fun' and inherent silliness in it and enjoys it that way. So I'm very thankful for that.
This is also why I'm not too into the realistic quicksand/damsel in distress type scenarios, although a playacting "Save me!" scenario is different.
