A hidden camera operator ingeniously conceals a camera within the saddle of a bicycle, clearly capturing upskirt footage of girls. Each pedal stroke naturally moves the camera, allowing for comfortable and steady shooting. The setup automatically adjusts zoom and focus according to the girl's movements, delivering realistic, immersive footage. Easy to install and nearly undetectable, this device lets the operator record without anyone noticing. Simple pleasures in everyday life are deepened through such clever techniques.
