Jake Johnson had been home from college for two weeks and was already bored to death. He had been away for almost four years and was pretty set in his ways. There was always something to do at school and he had a lot of close friends. In many ways his family had become strangers to him.
To beat the summer heat and bring the family closer together, his parents decided to take a trip down to the beach for a week. Jake had his doubts, but as he had nothing better to do he resigned himself to going. It would just be him, his parents and his little sister Allison. Allison, or 'Allie' as everyone called her, just graduated from high school and had just turned eighteen a few weeks before that. Jake was four years older and had never had much of a relationship with her. It wasn't that they didn't get along, they were just so opposite. Jake was outgoing and into sports. He was tall and athletic, taking after his father, and had gotten into college on a football scholarship. He was a little over six feet tall and well built, with short brown hair and brown eyes. Allie on the other hand, was shy and quiet. She had a cute little body though. She was short compared to Jake, standing only 5'7, and he noticed that she was filling out rather nicely. She was well toned and had a nice perky set of breasts. Her long curly brown hair and blue eyes only added to her beauty.
He couldn't help wondering what happened to that small flat chested girl that he left behind when he went to school. The Allie he came back to wasn't just beautiful, she was a woman. As they were piling their things into the family SUV, Jake thought about how little he knew of his sister. 'I don't know what she's going to college for or who her friends are or anything. I wonder if she's even had sex yet...' he thought with a wry grin, his mind wondering. Jake's father slapped him on the back and snapped him about of his thoughts. "Ready to hit the beach Jake?" his dad asked, getting into the car. Jake nodded and got in the back seat next to his sister.

The long ride to the beach house was an uneventful one. Allie was wearing sunglasses and reading a book, and Jake decided not to disturb her. He realized he wanted to though.
Allie was wearing a tiny pair of shorts and he couldn't keep his eyes off her smooth tan legs. He hoped she didn't notice him looking. He had to keep reminding himself this was his sister he was looking at.
They finally made it to the beach house. After getting out of the car Jake stretched and cracked his back and his neck. He couldn't wait to get in the water. Jake noticed Allie stretching as well, her back arching and her breasts threatening to spill from her tank top.
Allie wasn't very big. If Jake had to guess he'd say her breasts were a very full 'b' or a small 'c' cup. They were a little more than a handful but they looked perky and fit her small frame well. He fought his urges again. They were only harmless thoughts in his mind, or so he told himself.
Unloading the car didn't take nearly as long as Jake thought it would and before he knew it they were settled into the house and enjoying the fresh ocean breeze.
The house was well furnished and they each had their very own room. The kitchen was well stocked and the living room was spacious and had a flat screen TV.
It was only a little after three when they were done lunch and Jake's parents had announced they were going out shopping for a few hours... alone.
"What? Why can't we go?" Jake asked, dreading the prospect of being stuck inside, tortured by his sister's taunting of her barely clothed body. He didn't blame Allie, it had just been quite some time since he'd been with anyone. Jake wanted to hook up with a girl he could actually do something with.
Allie pushed her glasses up and into her curly brown hair, surprised as well. Much to Jake's dismay though, she remained quiet as she usually did.
"Sorry Jake, but your mother and I need a vacation too and we haven't spent any time alone in ages. We'll only be gone for a few hours. You have our cell if you need it. See you in a bit.... and have fun, it's beautiful day. Go down to the beach!"
They were gone within minutes and the silence in the house was deafening. He was alone with Allie and didn't have the first clue about what he should say to her. Luckily she broke the silence.
"Well, do you want to?" she asked, her blue eyes sparkling.
"Do I want to what?"
She laughed, "Do you want to go down to the beach?"
"We might as well. Not much else to do with no car."
She smiled and walked to her bedroom to change. Jake did the same. The thought of Allie in a bikini had him hard as a rock again and he debated taking care of himself the old fashioned way before they left. 'No, you don't have time' he told himself.
He put his swim trunks on and looked down at his cock pitching a nice visible tent. He put on a long t-shirt and hoped it would be enough to conceal it.
"Hey Jake?" called Allie.
He walked over to her room, which was across from his own and stopped like a deer in headlights when he saw her. She was wearing a tight red bikini top with matching red bottoms. The contrast between her chestnut hair, blue eyes and ruby red lips was almost more than he could handle. He wanted to throw her on the bed then and there.
"Can you help me apply some suntan lotion?"
Jake nodded and took the bottle from her as she laid down on the bed. Once she was comfortably down on her stomach, she reached around with one hand and undid the clasp on her top.
As he sat down next to her on the bed, her top fell a bit more and he could see the side of her breast, bare and tan like the rest of her. When he realized she didn't have a single tan line his cock grew even more stiff.
He squeezed some of the lotion into his hands and rubbed them together to warm it up. After, he squeezed a small circle of lotion her back as well, causing her to giggle.
She pulled her hair up and he started at the knape of her neck, working down along her shoulders and then further down along her back. When his fingertips accidently grazed the side of her bare left breast he bit his lip and moved down to the small of her back. He clapped his hands together and told her she was ready for the beach.
"You're not though. Let me do your back. You don't want to burn."
Jake smiled and turned around, taking off his shirt and holding it in front of his growing manhood. He knew he should refuse but the thought of Allie's bare hands running over his skin was too good of an offer to pass up, little sister or not.
She didn't disappoint. She shook the bottle a little and drew a thin line of lotion from one shoulder blade to the other, then another down the length of his spine. She put the lotion back in her bag and let it soak into his back a moment.
Softly, she placed the palm of her hand on the small of his back and rubbed the lotion all the way up to his neck. She then went to his shoulders and drew the lotion inward, firmly rubbing his neck a few times and working out some knots while she was at it. When she was done she laughed and ran her fingers through his hair, messing it up the best she could.
"Now you're ready for the beach too."
~~~~~~~~~~
Jake's father was right about one thing, it was a beautiful day. The sun was bright and the smell of the salty sea air was brisk and refreshing.
All they took with them were some large beach towels. Allie laid hers down and stretched out on her back to get a tan. Jake studied her for a moment and looked out to the ocean, debating.
"C'mon Allie. Don't tell me you're just going to lay there and tan all day. It's hot. Don't you want to go in the water?"
"It might be hot Jake, but that water is probably freezing."
"Only at first, you just have to get used to it."
Allie smiled playfully and and rested her hands behind her head. "I think I'll just lie here and let the sun cook me a bit. I'll be nice and warm, but the breeze will keep me cool enough."
Jake rested his hand on her thigh, "I guess I'll just have to take you in myself."
Allie's eyes grew wide and she suddenly sat up, drawing her legs into her chest and curling up into a ball.
"You wouldn't dare..."
Jake leapt to his feet and Allie made a sound, a scream or laughter or both. He had no trouble removing her arms from around her legs and easily lifting her up over his shoulder.
"Jake! No, no, no, no.... please! It's cold!"
He stopped for a moment. Allie seemed playful now but she could very well become pissed off if he ran down and tossed her in the water. He hadn't really seen her angry in years, but he didn't want to see it now and he certainly didn't want to be the target of it.
On the other hand, this was a chance to see Allie's tight little red bikini soaking wet and clinging to her body.
He ran for the water and Allie screamed. Once he reached the shoreline it only took a few short hops and he dove in, Allie still slung over his shoulder and hanging on for dear life.
The wall of cold water briefly wiped out all thoughts of Allie and her bikini. It also washed away the massive erection Jake was sporting, for which he was quite thankful. He rose to the surface and wiped his face, looking for his sister.
He knew at once it was all worth it. Allie pulled her hair back and squeezed it dry, looking none to pleased. Her top was wet and he could see small bumps where her nipples had become hard. She was hard enough to look at when she was dry, soaking wet she was torture.
They both grinned at each other, waiting to see who would make the next move. Before either of them had a chance though, the cell phone rang. In an instant they were kids again and racing to see who get back to the towel and answer it first.
This time Allie had the advantage. She was closer to shore and lighter on her feet than Jake. He wouldn't be defeated so easily though. As soon as she made it to the towel, he caught up with her and tackled her into the sand.
