She wants to immortalize the moment as the cum flows over her tongue, to feel the warmth and texture of it mingling with her saliva, to see the white droplets trickle down her lips and hear the smacking sound of her mouth closing over them. She wants to capture the expression of pleasure and satisfaction on her face, to remember how she managed to make him cum so hard and so fast. She wants to preserve that image forever, as a testament to her oral skills and her devotion to him.
