Zack and Ansley were always the best of friends. The siblings fought, partied, lived, and played together like normal siblings do. For the longest time as well, they were always getting closer than siblings probably should. They shared their "first kiss" together when we were just a mere nine years old, just playing around in the backyard, but they never really thought of themselves as lovers until later on...
It all began the summer when Zack turned 19 and Ansley turned 18. That summer was the beginning of trouble as their parents had left them for a luxurious Caribbean vacation, and they had to stay and housesit. Since they were normal 19 and 18 year olds, Ansley and Zack spent 99% of the time partying, and the other percent sleeping, eating, and just chilling about the house.
Now, let me tell you about the house, they were born into a blessed family, so the siblings never went without a thing unwanted. The house was a large ranch in the middle of the country, but not too far away from everything, just far away enough to get some peace and quiet when needed. It was a two-story house, with a finished basement, large garage, grand pool with a beautiful waterfall overlooking the country side. So as you can tell, they spent a lot of time outside, giving Zack and Ansley a deep all-over tan.
That summer was Ansley's graduation summer, and Zack's freshman year of college. Their parents left them near the beginning of the summer, right after Ansley's graduation. Ansley was rather sad that her big older brother Zack wasn't there to see her graduation but promised to make it up to Ansley when he could get away from college.
When Ansley heard his car pull up she was just slipping into her bikini, a rather modest one today since she knew Zack was coming into town, a bright yellow one piece with a bandeau top and a high riding bottom. Also that morning, she had shaved her pussy so it was extra smooth, and that she looked almost flawless. Ansley swept her hair back into a loose ponytail, and threw on her purple Polo hat.
Ansley stood looking out my window for a little while, watching Zack put his car into park, unbuckled, and opened his door. After she watched him get out, she slipped on a pair of super-ripped shorts and walked down the stairs, through the foyer, and out the front door to go greet him. As he was bent over getting his stuff out of the trunk, Ansley sneaked up behind him and grabbed him around the waist, giving him a tight hug from behind. At her touch, he immediately stiffened and muttered something incoherent. She released her grip as he turned around to look at me.
"Damn it Ansley, what the fuck is wrong with you?" She stepped back and looked at him and bit her lower lip, trying to hold back laughter while still trying to maintain the innocent look.
"Sorry Zack, I just was trying to give you a hug. Since when do you hate affection?" She finally said, smiling. He broke his stern look and smiled with all of his pearly whites and his light baby blue eyes that made just about every girl in town melt.
"I don't repel affection... I just don't like to be assaulted from the back." He said this and immediately regretted it.
"THAT'S WHAT SHE SAID!" She practically yelled, then jumped back onto him to give him another hug. This time he gave in and hugged her back, and she swore she could feel his crotch twitch a little. Ansley released him and told him that she was going to go work on my tan and cool-off a bit by the pool and that when he finished getting unpacked for him to head down so they could catch up a little.
"Damn she looks good." Zack mumbled to himself as he watched Ansley strut away from him. He had just hugged her and already felt a little twitch and growing in his cock.. Zack quickly grabbed his things out of the car, and walked up to the steps to the place he called home.
Once he is was in his room, he had thought about his sister all the way up and his cock was aching in his shorts. He closed the door, stripped naked and started to rub the length of his long shaft ever so slowly. He thought back to the times that he had watched her sleep, take little peeps at her when she was getting dressed. He collapsed back on his bed, stroking all ten inches of him faster now, feeling the cum start to rise in his balls. He jerked hard one more time, and he felt his hot sticky cum spurt in the air, on his toned stomach, and muscular thighs. He cleaned himself up quickly, and dug around to find his swim trunks.
Downstairs, Ansley was laying on a float in the pool, trying to stay as dry as possible. She was also a little horny and wet from the cock twitching experience from her brother. Was that really from me? She thought as her fingers caressed the sides of her thighs and as they involuntarily parted, she moaned. She knew if she was going to do this, it'd have to be quick.
Ansley took a quick peek around to check if Zack was near, then pulled her bathing suit bottom to the side, and concentrated furiously on her clit. She arched her back and moaned, it had been a while since she had gotten herself off, and she knew it wouldn't take long.
Zack headed down the stairs in his trunks, and heard someone or something moaning. As he turned the corner into the kitchen, he saw his little sister lying on the float with her back arched and her fingers between her legs. This site caused an all too familiar twitching in his crotch and he involuntarily reached down and rubbed his fast growing and aching member. As he watched his sister get herself off, he suddenly felt a little guilty watching her, knowing that he would be angry at her if she saw him. But he couldn't take his eyes off her, now her eyes closed tight, mouth open, one hand rubbing the hard nipple through the thin fabric and a hand furiously moving between her toned thighs. Suddenly she stopped, twitched, arching her back a little more, finally collapsed back onto the float, breathing hard and deep.
Damn! Thought Ansley as she composed herself back onto the float, that was so good. Her breathing came back to normal as her climax-induced high brought her back to earth. She looked over at the door, and she saw Zack walking into the backyard, his swim trunks a little low so she could see his finely chiseled body. She turned her head and smiled as she slowly paddled herself back to the side of the pool as he got near.
"You need some help?" Zack said in his all too loving brotherly voice. She smiled up at him, but then thought back to all those times that he had said that and thrown her into the pool. She looked up at him with her big doe eyes, and replied
"No, I got it." Zack looked down at her, seeing as her top was a little disheveled, and he swore he could see a wet spot over the top of the fabric between her legs. He watched her lift herself out of the pool, and then sit on the edge of one of the pool recliners around the deck. She turned her back to him as she fixed her towel on her chair, and then laid back and looked at him and smiled.
"Take a picture would ya?" Ansley said jokingly. Zack smiled at her comment, and thought about it for a moment. Shaking his head and rolling his eyes, he took a seat on the recliner next to her.
"So how have you been?" Zack reached for the tanning oil on the table between them to put some on his shoulders, stomach, and legs.
"I've been good, well I would've been better if you could've came to my graduation." She replied with her little girl voice. Zack sighed and replied,
"You know I couldn't make it, I had my finals. I told you I'd make it up to you." He set the tanning oil back on the table.
"I know, I know." Ansley said as she grabbed the tanning oil back off the table and started applying it. As she struggled to reach her back, big brother Zack got up and took the oil from her, squirted a little in his hand and slowly rubbed it into her back. She smiled back at him as she lifted her hair out of his way. He finished, looking at the sexy small of her back, and the delicate curve of her bottom on the fold of the chair. He set the oil back down, and laid back on the chair. They stayed like this until the sun started hiding between the clouds and they heard a distant clap of thunder.
