In the library's quiet, she's anything but. This teen, a picture of schoolgirl innocence with her uniform skirt and white blouse, is anything but. She's on her knees, her textbooks forgotten, as she practices her newfound oral skills. Her tongue flicks out, tracing the veins of the cock presented to her. She takes it deep, her eyes watering slightly, before pulling back, leaving a trail of saliva. She's a quick learner, her pace increasing, her enthusiasm infectious.
