When a girl walks down the street in such a short skirt and with an anal plug, it's clear that she's looking for an adventure for her ass. Licking ice cream is just an added touch to this image of a bitch. So her verbal signs were quickly understood and she even squirted while being fucked in the ass.
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.
