As for me the lady is not very pleased with this kind of sex! The expression on her face never showed that she liked it. I think she would have enjoyed it more if she had served the men one at a time. And the two of them just bore her. Did the lady enjoy herself? I don't think she did.
A lot of girls dream of starring in movies, so any director can take advantage of that. Besides, the brown-haired girl is really very sexy and it's hard to resist here.
