In a dimly lit room, a voyeur's gaze is drawn to a tantalizing scene. A man, cock in hand, begins a slow, teasing stroke. He knows he's being watched, and the thrill of exhibitionism fuels his desire. His dick twitches, growing harder as he picks up the pace, playing with his foreskin, revealing the glistening head. The voyeur's heart races, their own body responding to the boomerang of lust.
