This is mine and many other's favorite, pissing.
This genre is exploding and many new things are tested, great!
One company that has been doing this for a long time is 666. One thing they sometimes do which is fantastic and should be done more often is to have one guy ejaculate and another guy pissing in the girl's mouth at the same time i.e. she mixes the piss&cum cocktail in her mouth. Lovely!
In the beginning it was always just the boys pissing. Luckily we get more girls pissing both in each others mouth but also on the guys. I wouldn't mind having two girls alternating pissing in my face and I want to see it in movies.
When girls are pissing it is especially delightful if she is standing with spread legs, spread ass and open asshole. Then while pissing a guy steps forward and puts his dick in her ass and starts to fuck her while she continue to piss.
I haven't seen all your scenes but I bought three today and I will buy more if I see that they develop based on our dialogue.
