Infiniteheart presents an extreme solo session as an eager amateur explores the limits of his desire. With a steady hand, he inserts a tube into his urethra, slowly filling his cock with air, watching in awe as it expands and hardens. The sensation is intense, a sweet torture that drives him closer to the edge. He pauses, takes a deep breath, and then, with a groan, releases the air, his cock pulsing with relief.
