She must know I'm watching...
He walked out onto the upstairs deck that sunny mid-morning to clean the bar-b-que grill from the night before and happened to glance across the wall around it and into the neighbor's back yard and saw Annie's sister Gail in the back yard. She was wearing a white t-shirt and very short cutoff jeans, her dark hair tied in a ponytail. She was apparently weeding the flowerbeds that bordered the privacy fence around the back yard.
He watched her for a while, and she stood and stretched her back. It was now clear she was not wearing a bra under the t-shirt as he could faintly see the outline of the nipples of her firm breasts making little peaks in the material. She moved to the next section and glanced up and must have noticed him watching her. As she bent to pull the next weed she kept her legs straight, feet slightly parted, and the shorts stretched across her backside and the bottom crease of her butt cheeks were slightly exposed. She did this a couple of times and he moved to the spotting scope on the tripod by the wall and focused in to get a better look. He could now see that the shorts exposed quite a bit of her derriere, the denim running between her legs in a thin blue line and as she turned it was clear she was braless.
She paused and looked at the length of the flowerbed at the base of the fence, dusted her hands together and walked up onto the cement patio and moved a chaise lounge into the center. She may have glanced his way as she walked to the back door and opened it and as she walked through, her back to him, she reached down and pulled the t-shirt over her head and off.
He stood there for a few minutes. She had looked his way. Had she seen him? She must have seen him standing there but she had given no indication. Perhaps she hadn't noticed him.
As these thoughts went through his head, Gail walked back out onto the patio wearing a white bikini, a towel draped over one arm and a bottle of oil in her hand. She draped the towel over the back and down the seat of the lounger and sat down, leaned back on the angled backrest and straightened her long tan legs in front of her, crossing her ankles.
He returned to the 'scope and watched her as she snapped the cap open on the bottle of oil. Extended one arm, she squeezed a line of oil from her wrist to her shoulder. Set the bottle down and rubbed the oil into her tan skin, moving her hand up and down her arm until it was shining. She repeated the process on the other arm and then leaned back and drizzled a line of oil just below her neck from shoulder to shoulder and began to rub that in as well. Her breasts were moving under the tight bikini top as the skin at the top of her breasts became shiny with oil.
Watching her he felt his manhood stir and rise, straining against the swim trunks he was wearing. He moved one hand down and slide it inside the waistband and gripped his now erect cock, stroking it slowly.
