I started with slow caresses on his back, eventually transitioning to his legs and feet as he gradually unwound under my touch. However, it was evident that there remained unresolved tension elsewhere in his body, prompting me to shift focus towards his shoulders and neck. I delicately worked on untying the knots present while applying a gentle kneading motion. During this process, I noticed how erect he had become - not solely due to the massage but also in anticipation of what might follow. His breathing grew heavier, and he subtly shifted in his seat. Sensing an opportunity for something extraordinary, I proceeded with my plan. While maintaining a steady rhythm on his upper body, I reached down between his legs and began stimulating his cock through his trousers. He looked shocked but didn't object - instead, he moaned softly while I continued pleasuring him. With one hand still focused on his back, I used the other to unbutton his pants and reveal his erect member. His eyes widened at the sight as I wrapped my fingers around his shaft, applying consistent pressure while massaging his shoulders simultaneously. As I picked up the pace, he groaned deeply in pleasure. His hips bucked involuntarily against my hand, seeking more friction. Sensing that he was nearing climax, I decided to elevate our experience even further. While still stroking his cock with one hand, I moved the other between my legs and started stimulating myself through my undergarments. His gaze locked onto mine as he observed me masturbating while providing him with a hand job. He was now completely under my command - and loving every second of it. Within minutes, he tensed up and cried out as he reached an intense orgasm that coated my hand. I continued massaging his shoulders as he recovered from the powerful release, feeling proud of myself for having provided him with such a memorable experience. From then on, offering clients a happy ending became a regular part of my job - but none would ever surpass the exhilaration of satisfying this particular client.
