Rusty, a grizzled, hairy grandfather, finds himself alone in the bathroom, a familiar setting for his daily ritual. His small, veiny cock stands at attention as he strokes it eagerly, the sound of his heavy breathing echoing in the small space. The toilet provides an unsteady seat, but Rusty is undeterred, his lust consuming him. He continues to pump his cock, his balls tightening as he nears his climax. With a final groan, he shoots his load, the cum splattering onto the toilet seat and floor, a testament to his solo indulgence.
