He glided through the water with smooth strokes, his muscles rippling with each movement. The light of the three-quarter moon was enough to see he swam in the nude. Why not? It was a private pool, after all. Private, that is, unless you knew exactly where to sit on your neighboring roof and watch.
She idly chewed a fingernail as she watched him swim his nighttime laps. The night was warm, perfect for a swim. She wondered how he would react if she were to join him. She'd been watching him since the half moon the month before. Though, even when there wasn't moonlight, the stars provided enough for her to watch him. For some reason, he preferred swimming at night, under the moon and stars, without turning on any lights.
She sighed and could have sworn he actually heard, as he seemed to turn his head her way. No, her imagination, she decided. What would it be like to join him in the water? Skin on skin with the warm water swirling around them? She shivered at the delightful images that once again filled her mind at that thought.
That's it, she decided suddenly, she was actually going to take the step of going down there. She knew where the gate was and that he had a latch on the outside. Unless he'd locked it from the inside, she could get in the gate. Even if he had locked it, the sound of her trying to open it would distract him from his swim.
She slipped back down the roof and into her bedroom, and then tugged off the cut-offs and halter-top she had worn to the roof and pulled on just a swim robe. The terrycloth robe came down to her knees, the sleeves ended at her elbows. She belted it, gathered her nerves, and headed into the darkness.
The gate was unlocked. And nicely oiled. She slipped into the backyard silently and made her way to the pool. She was struck by the up-close view of him swimming through the water, so much more personal than the view from her roof. She watched him for several minutes, hands gripping the belt on her robe.
Then he suddenly stopped, treading water on the opposite side of the pool from her, facing away and watching the moon.
"I was wondering when you'd finally get up the nerve to join me," he said conversationally, "It hasn't always been easy to swim knowing you were watching."
She jumped in shock. He'd known she watched? He'd been expecting her?
He turned to face her and swam over to the side of the pool, "Now, don't get all shy now that you're here, come join me for a swim," he smiled charmingly, then his eyes glinted in the moonlight with mischief, "I sincerely hope you didn't bring a swimsuit."
She blushed at that, then slowly untied the belt of her robe and nervously let it gradually fall to the grass.
"Mmmm, nice choice," his eyes glinted with something else now, she wasn't sure exactly what, but her libido kicked at her with a very good idea, "Come on in," he added, "it's perfectly warm, almost bath temperature."
She started to go to the stairs, and then decided to join him with style. She quickly stepped to the diving board and executed a perfect dive into the water. When she came up, he was waiting just out of reach. They stared at each other over the water for a minute.
"You were expecting me," she broke the silence, treading water and keeping just out of his reach.
He shrugged, "Hoping more, really. I could see you up there every night watching me. Like I said, it made swimming difficult at times, wondering if you would actually come down here to join me, what could happen if you did."
