Pixie knows she's failing your class, and she really needs to pass. She's been staying up all night studying, and even that isn't enough. But she has a trick up her sleeve, she's seen you staring at her when she yawns, and she's worked out your secret, you have a yawn fetish don't you! Maybe, if her grades improve, she could keep your little secret, and even yawn for you after class? She yawns through out the clip - as well as taking off her shirt and bra. Good deal right
