In the quiet of the library, a studious student, hidden behind a towering stack of books, indulges in a secret vice. He slips his hand beneath the table, unzipping his pants. His cock, already engorged, throbs eagerly. He strokes it with practiced ease, his eyes scanning the room, seeking any sign of discovery. His breath catches as he spots a librarian, her skirt short, her heels clicking. His pace quickens, his grip tightens, and he comes with a quiet, shuddering gasp.
