A uniform-clad schoolgirl finds herself in detention, but her teacher has other plans. He locks the door and approaches her desk, his intentions clear. Her heart races as he lifts her skirt, revealing her innocent white panties. He runs a finger along her slit, feeling her dampness. She gasps, her eyes wide, as he pushes her panties aside and slides a finger into her tight, virgin pussy. She squirms, but he holds her down, working her pussy with expert precision, bringing her to a shameful, trembling orgasm.
