The first time is always hard. The blonde with her questions aroused her girlfriend and offered to try sex with a girl. And she secretly dreamed about it, so this step was not so difficult for her. When girls fondle each other, the male gets a hard-on just like he does himself with them. Glad the girls did it. That's so hot!
Well apparently the girl was going to porno casting and was ready to be fucked in the anal, and her mouth, and everything on her body, because that is what porno casting is for, to check how good a girl is.
