Dr. Muscle, in his crisp white coat, retreats to his private office, the scent of antiseptic replaced by the musk of his arousal. He strips, revealing a chiseled, hairless physique, his thick cock already tents his boxers. He strokes, the sound of his lubed fist echoing in the sterile room, his mind filled with forbidden fantasies. His breath hitches as he imagines rough, sweaty encounters with his patients, their moans of pain morphing into pleasure. He explodes, his cum coating his abs, a satisfied groan echoing in the empty room.
