Thanks for the identification work guys.
Again some convincing is involved in some scenes, and some of the case are borderline, bu not all, Ester did for example say no when he entered her but after a few thrusts she was kissing him with passion and exchanged a few positions, even with her on top where she could just go away, the situation probably got her more turned on.
Apart from the mentioned borderline cases I think that most of us would agree that a large number of these girls are just little whores who are more than willing to get on their knees and suck a cock or spread their legs and get fucked bareback by a guy they met 15 minutes earlier if they find him attractive or believe that it will get them financial gain or pleasure.
