I returned to the cove, stretching as I viewed my conquests. Anna happily swam around the pool, her purple tail shining in the light. Lauren was sleeping in the corner, her green tail flicking in her sleep, a result of unsettled dreams. The newest arrival was crying, and fiddling with something on the ground. I looked over at her, wondering what she was doing. Still sobbing, she lifted up two seashells. After using seaweed, she fashioned a makeshift bra, struggling against her newly larger breasts. She and Lauren had not totally fallen under my harem. Anna though had fully given in, and even as I watched she noticed and have me a wink, then beckoned her finger. I wonder what I should do now, indulge my need and fuck sis yet again, or find new blood for the cove?
