Girl with big butt notices a voyeur is filming her

Of course a voyeur was filming her. That bikini is like a string thong and she was bending over constantly right in front of him. Well, once she lied down to sunbathe, her friend signaled her about the voyeur and that he was pointing his phone camera right at her marvelous big butt. She reacted but that smile on her face actually gave her away, she was flattered along the way.
