Hidden behind a two-way mirror, a voyeuristic student witnesses her professor's private indulgence. The room's dim light casts a soft glow on his naked form, his silhouette a stark contrast against the desk. He's a sight to behold, his thick, veined cock in his hand, his rhythm steady and confident. The student's breath hitches, her heart races, as she watches him edge himself, his pleasure evident in every stroke. His orgasm is intense, his body tensing, his cock pulsing, his cum coating his hand and the desk.
