In a private sanctuary, a man, bound by the rules of his past, indulges in a solo CBT session. He teases and torments his engorged cock, pushing boundaries, seeking the edge. His body tenses, muscles clenching as he nears climax. With a guttural groan, he spills his seed, the pulsating release echoing through his being, a fleeting moment of freedom from his self-imposed constraints.
