The latest piss scenes definitely seem to be moving in the right direction, although I would still like to see more swallowing. Lucia Love seems to be the best swallower. The other girls should watch her and follow her example!
And I would also be willing to pay an extra ticket or two for a scene that had lots and lots of swallowing.
Maybe you could bring in a couple of extra guys to supply more piss. They don't even have to be real porn stars, as they would just be there to piss, not to fuck, so it doesn't matter if they have small dicks, wood problems, etc.
