The classroom is empty, but the air is thick with unspoken desire. Lovely, the bookworm, is left behind, her innocent eyes meeting her teacher's knowing gaze. He moves closer, his aged body betraying his arousal. She swallows hard, her mind racing, but her body responds, her pussy dampening her panties. He leans in, his breath hot on her ear, "You're a good student, Lovely. But I think it's time you learned something... different." She nods, her eyes wide, as he unzips his pants, revealing his stiff, veined cock. She tentatively reaches out, her small hand wrapping around his girth. He guides her, his hands firm on her head, as she takes him into her mouth, her innocent lips stretching to accommodate his size. She gags at first, but he's patient, teaching her the art of pleasure, his aged body shuddering as she learns to take him deeper.
