Those tits look huge, just like her hands. And as others have said, her head doesn't look right (edit it, so she doesn't look so fat). If you look at the last pic of her holding up her tits, you'll see that her arms are wavy/deformed because of poor editing. Which means she is a big fat girl, to match her big fat tits.
I'd imagine that some guys see her then walk out the door. So she might give discount if you ask for a lower rate. I don't mind a big girl, but I would still ask her for a lower price.
