Numbers dance on the screen, a code only he understands. As he types, his mind wanders, his imagination running wild. He pictures the girl from his math class, her perky breasts, her laugh that makes his heart race. His cock hardens in his pants, pressing against the fabric. He glances at the door, then quickly locks it, unbuckling his belt, his pants pooling at his feet. He grips his cock, his strokes firm and steady, his mind filled with the girl he can't have. His body tenses, his cock pulsing as he comes, his release coating his hand, his breath ragged.
