As she wondered what exactly had happened to her breasts overnight, her confusion steadily turned into discomfort. She needed relief. Still groggy from waking up, and halfway believing it was just a dream, she took off her shirt, and then glanced at her still asleep sister Tiffany. Why not, she thought, and gently grabbed her nipple and eased it into her mouth. Tiff instinctively started sucking in her sleep. Olivia couldn't help but writhe from the relief, and guided Nikky to the other breast as fast as she could.
After a time, both of them had finished, and Olivia lay there; in the back of her mind knowing there was something wrong with breastfeeding her sisters, but mostly all she could think about how it was the most pleasurable thing she had ever experienced.
Just then, Tiffany woke up. "Hey Sis, what's up?", she asked sleepily.
