$13,000 to do girl on girl is waaaaaaaaaaay too much. I've got two friends who are reasonably well-known, experienced porn actresses and they don't get even a quarter of that for g/g scenes.

The highest paying porn company in Australia pay $1000 per girl for a g/g shoot, and most US porn actresses I know say that they want to come and shoot here cos our pay rates are really high.

Unless you're like a Vivid or Club Jenna contract girl those rates just don't seem legit, no matter how much a company might try to persuade you otherwise.
