The sailor slipped over the side railing, letting the cool water claim his body again in his nightly ritual. The minute differences in temperature slipped and swirled around him as he moved silently away from the ship. Following the ribbon of moonlight on the water, he let his breathing slow and the rhythm of the sea take him. Soon, he was moving with powerful strokes down that moon's road. And then, from the corner of his eye, he saw her.
She was moving parallel to him, out of the light and barely visible. Still, he caught the flash of her white face peek out about the lapping waves before disappearing swiftly again beneath them. He stilled. Treading water carefully, he looked around and around himself, spotting the ships bulk in the distance, desperately hoping for another glimpse. There she was again. Still off to the side but closer this time. He could just make out a moonlit slick of hair and huge liquid eyes and her pale face before she submerged again. He hardly dared to breathe. Knowing them to be only myths, still his heart had yearned his whole life to see one, to know they had always been real. He turned round in the water, every sense alert. Then he felt, not even a touch, but the barest disturbance in the water surrounding him. Taking a deep breath, he allowed his body to stop completely, slipping beneath the water. Then he opened his eyes.
There she was. Not two feet from him. Barely visible but somehow glowing. Her long hair floated around her like a nimbus, pale like her skin above the waist. He drank in the sight of her. Her perfect breasts, her long arms, her mermaids tail beautiful and glinting, swishing gently to hold her in place. She regarded to him steadily, with frank curiosity. He blinked, belatedly registering the need for oxygen. He pushed up, breaking water. He gulped a few breaths, blinking rapidly and registering the sensations in his body. The racing pulse, the rapid breathing, his skin electrified and tuned to every minute swirl of the water around him. And, almost as an afterthought, his thundering arousal, penis stiff as a ship's mast in front of him. He gulped a few more breaths and then she came into view above the water again.
"Hello." It came out a croak. She tilted her head quizzically. He cleared his throat and tried again. "I never thought I'd see anything like you."
Her red lips parted and she made a strange chirping sound. Then she dipped back below the water again. Frustrated, frightened he'd scared her away, he turned in a complete circle. Then gulped as much air as he could hold and sank below again.
She was right there. In the act of reaching toward him. Up close, he noticed the minute differences. Her skin, almost like it was lit from within. Her eyes, slightly larger than human and some indeterminate color in the murky water. Her teeth, dainty and pointed, showing faintly between her parted lips. And her tail. It was a wonder. From this distance he could make out the individual scales, metallic blue-green and close-set, merging seamlessly with the skin just below her belly button. His gaze traveled up her body, and he felt unwontedly shy staring at her, despite the innumerable breasts he'd seen in so many ports of call.
