And it was at that moment that I realized that she was not doing this for my benefit. She was not trying to entice me nor did she want to engage with me. She literally wanted to cum. My presence there was a bonus for her. She would have done it with or without me in there. And I watched as she achieved orgasm. Her shivering, her biting her lower lip, her closing her eyes, lowering her leg, her breath having increased in sound and decreased a few seconds later. The beauty of that loss of control made me wish I had experienced her.
