In the dimly lit confines of his private study, a mature gentleman, known only as Professor1955, indulges in a solo session of pure carnal pleasure. His experienced hand wraps around his throbbing cock, stroking it with a rhythm born from years of intimate knowledge. The room fills with the scent of his musk, the sound of his heavy breathing, as he brings himself closer to the edge. His body tenses, his grip tightens, and with a low groan, he releases, his hot cum spilling out, coating his hand and the worn-out pages of the book he'd been using for his illicit pleasure.
