I'm not a hardcore fan of Wet & Messy fetish (for example I don't like it overdone where you can't even recognise the model) but I did find this interesting video recently which combines knicker fetish with a little bit of messy action:

I'm not sure if this would be possible on this family of websites anyway but does anyone else like this concept?
