The summer was looking very promising for the Frost family. Blake had just graduated high school. Silvia had just graduated university with a degree in psychology. Aaron and Vivian Frost, parents of Blake and Silvia had just purchased their first summer home on Lake Williams, one of the nicest bodies of water in the state.

The evening that Silvia arrived home from college with her Prius stuffed from top to bottom with her things, Mr. And Mrs. Frost cooked a wonderful dinner with grilled lobster, steak and vegetables. They were excited to tell the kids about the new house.

As they were eating a delicious blueberry pie that Mrs Frost had baked, Mr. Frost poured himself a glass of wine and told them.

"Kids, you know that lake we go to every summer and stay at a campground a couple weeks every year?"

Blake and Silvia had always loved it. Blake fished for trout everyday in a row boat and Silvia usually bronzed her body and swam in the lake all day. Back and forth from the beach chair to the water.

"That's the best place, dad!" Blake exclaimed. Silvia seemed enthused by the mention of a good vacation. "Oh, yes. When can we go?" She asked.

Mrs. Frost began to clear the dinner dishes from the table. "We have a big surprise for you, tell them dear," she said. Blake and Silvia looked at Mr. Frost with curiosity.

He smiled wryly. "Well kids," he said. "you're not going to believe it but we bought a waterfront house at Lake Williams."

"No way dad!" Exclaimed Blake. Silvia put her hand over her mouth. Blake thought she was going to cry. "Are you going to tear up because mom and dad bought a summer house?" He teased.

Mrs. Frost scowled at Blake. "For goodness sakes honey, do not make fun of your sister! Women sometimes cry when they are happy. Get used to it."

Mr. Frost poured his wife some wine and topped off his glass. "Ok, no fighting. No making fun. Whatever. I know you guys are best friends." He sat back in his chair in contemplation, watching the cabernet swirl in his glass as he held it to his lips. He looked at Vivian, God he loved that sexy woman. A brilliant thought was descending upon his mind.

"Honey, I have an idea," he said.

It was Sunday night. Mr. And Mrs. Frost had just closed on the house the day before. Both he and Vivian were so excited to get there and relax. Unfortunately they both had a busy work schedule coming up. Mr. Frost addressed Blake and Silvia.

"How would you guys like to spend the week getting the house ready?" Silvia's eyes about popped out. Blake immediately stood up. "No way! Are you kidding?" Mr. Frost knew already that Blake was imagining a week of evening fishing for trout.

"Your mom and I towed the boat up yesterday. If you two are careful you can run it," he said.

Blake looked at Silvia, ecstatic. "Hell yes, right Sil?" She too was excited beyond belief. She thought about sitting by the lake in her bikini, reading, maybe even tanning her breasts, if it was private enough. "Yes, little brother! Let's do it!" Mr. Frost held up his hand and took a long sip from his glass. He looked at Vivian.

"Honey? When does the truck get there?" Mrs. Frost retrieved her phone from her pocket. She had arranged for some movers to bring furniture and kitchenware. She checked the date. "Oh," she said. "It will be there Tuesday at 10 A.M." Mr. Frost nodded and smiled, looking at Silvia.

"Baby, i want you to figure out where everything goes." He turned to Blake sternly but still wearing a smile. "Son..." he paused. "Do what your sister says."

Blake looked at Silvia, smiled broadly, and nodded. He laughed. "Dad, I have no idea where shit goes," he said. Good choice!"

Everyone laughed. They all knew how disorganized Blake was. If he had to set a table right or be killed, he would die. He would store the towels and sheets under the kitchen sink for all he knew or put the silverware in his sock drawer. Sports and fishing. He knew that.

Mr. Frost finished his wine and smiled mischievously at Vivian. She blushed. He grabbed her around the waist and kissed her. Blake looked at Silvia and rolled his eyes. Their parents had never hidden their attraction For each other. His bedroom was closest to theirs. Silvia was the first person in his life to tell him about sex.

He was maybe 8 or 9. He remembered running to Silvia's room one night grabbing her, shaking her, waking her up, whispering loudly. "Silvia Silvia! Something's wrong with mom and dad!" They had stood outside their parent's door and listened briefly. He remembered Silvia snickering quietly and leading him back to her room with her finger over her lips as if to say, "shhh." And their conversation was the only time in his life up until then, someone older had talked with him about sex. They sat up for hours with the lights on.

"Why was mama saying she was going to make dad her bitch? I heard her slap him!" Blake remembered that conversation with Silvia vividly. "She was mad at him Sil. I know she was. She hurt dad. Dad sounded hurt!" He remembered Silvia rolling on her side laughing.

"They're having sex!" She had said "I don't know about making someone else your bitch, but they were having sex."

It was the one and only "birds and bees" conversation he ever had.

Silvia did not unload her Prius but drove it directly to lake Williams the following morning. Blake followed in his old ford truck filled with some furniture and beddings that Vivian wanted him to bring.

The siblings spent the rest of the day unloading their cars. It was hot. Blake changed into his swimsuit and ran into the lake. Silvia was reading on the porch.

"The water is soooo warm!" Blake exclaimed. He dove to the bottom of the clear lake and grabbed a handful of tiny rocks. Finding his footing, he threw one onto the porch next to Silvia. She looked around and then looked at Blake who was grinning.

"You better not hit me!" She warned, quickly returning to her book. A few drops of water splashed at her feet. She was not in her swimsuit. Blake was approaching the beach, kicking water at her.

"Damn it Blake! Do not think about it!" She declared. Blake laughed as he walked out of the water.

As Silvia watched him, she felt something was different. She thought a moment. Yes, that was it. He had filled in. His arms, his shoulders, his chest. Everything. Silvia watched him with her mouth open.

"Take a picture." Blake teased as he dried off with his towel. Silvia pretended not to blush and went back to reading.

After a dinner of left overs, Silvia tidied up the kitchen and Blake tried some fishing from the shore. She watched him, trying to ward off the growing realization that she had suddenly developed an attraction for her younger brother. Nothing was right about that.

Blake came in at sunset and walked to the kitchen. Silvia watched him from the sofa. "Why don't you put a shirt on little brother." She requested, still trying to read her book. Blake opened the refrigerator and found a can of mineral water. He popped it open and looked at Silvia, confused. He took a long drink.

"Why do I need a shirt?" He asked. Silvia smiled and shook her head. "Because you look really damn good," she said.

Blake turned beat red and set his water on the counter top. "Uh...what are you talking about," he stammered.

Silvia closed her book and looked at him tenderly. "We have always been honest with each other." She paused to search for words, watching his bare chest. "Today, when I saw you get out of the water. I felt attracted to you," she admitted. Blake looked at her wide-eyed with his mouth open. He had nothing to say. They spoke no more about it that evening.

The following morning the movers arrived early. Silvia had them place everything just where her mom had requested. She personally unpacked all the kitchen ware and placed everything in the cabinets and drawers. Soon it began to look and feel like a real house. Blake had done little but shuffle boxes and items around for Silvia. When they were finished, Blake walked around the living room and kitchen, impressed.

"How do you know how to do all this Sis?" She had hung mirrors and pictures and had arranged chairs and another sofa perfectly. Everything looked perfect to him. Silvia smiled.

"Oh, I just know how." She winked at him and opened the refrigerator. "What I don't know how to do is make food magically appear." She looked at Blake. "I'm going to town and shop. I don't suppose you want to come?" Blake winced and shook his head. Silvia laughed. "I don't think you'd be much help would you."

She left for town and Blake changed into his swimsuit. It was super hot. Too hot to fish. Blake swam in the lake until his body cooled down. He dried off and sat in the recliner on the porch looking out at the lake. On the table beside him Silvia's book caught his attention. There was a picture of a shirtless man holding a woman. He suddenly wondered to himself what sort of thing Silvia read about. She was always reading something.

He began to read it and it seemed boring. It was a long book. He kept flipping through the pages just trying to get the gist of it and noticed that Silvia had several pages bookmarked with post it notes. He began to read the first marked page. His jaw dropped and he put his hand over his mouth as he read.

It was a pages long description of a Lady named Carla giving a blowjob to the guy on the front of the book who was named Rick. He read the whole scene and sought out Silvia's next post it note. Blake had never had a blowjob. He had never read about one either. Carla in the book sounded like she was really good at giving them. Silvia had another blowjob scene marked. Blake fixated on it. He was not aware that his cock was beginning to rabidly punctuate his swim trunks. As he was reading the part where Carla was just about to swallow down all of Rick's cum, he heard a sound behind him. Suddenly, there was a hand on his shoulder. He startled and dropped the book on the porch.

"How long have you been here?" Blake asked, still panting from being startled. Silvia laughed. "Long enough," she said, looking at Blake's swim trunks. Blake immediately leaned forward covered his lap with his arms, completely embarrassed.

Silvia returned inside and began to put groceries away. Blake picked up Silvia's book and placed it back on the side table. He wanted to know how Carla had finished her blowjob but he could find out later.

"Blake!" Called out Silvia. He made eye contact with her through the door. She smiled at him. "I didn't want to cook, and I know you can't so I bought Thai food."

They ate on the porch together and watched the lake. Silvia had changed into her bikini and sundress. When they were nearly finished she picked up her book and looked at the cover.

"Now you know what I like to read about little brother," she said.

Silvia returned to the kitchen and moments later returned with two cold beers from the refrigerator. Blake looked at her with awe and gratitude. His parents would not let him have anything like a beer. "Don't worry Blake." Silvia looked at him assuredly and sat down next to him. "We have more."

The evening was still very warm. When they had each finished 3 Heinekens, Silvia rose from her seat and stood at the top of the stairs leading to the beach. "It's so warm," she remarked, standing right in front of Blake. She dropped her sundress to her feet and watched the sun. It was low in the western sky.

"Isn't this place amazing?" She asked, leaning over to stretch her legs. Blake watched her body. Her skin was a perfect dark olive tone, her legs so nice and long. She wore a red thong bikini and Blake found himself staring at her perfect round tight ass. He had to look away. Suddenly she ran down the stairs and dove into the lake.

Silvia had been a college swimmer for 3 years. Blake watched her freestyle out and back nearly 200 yards. When she returned she was not even tired. There was no way he could do that. No way. She got out of the lake and sat beside him without drying off. The sun was setting. Silvia shook her hands off and picked up her book from the side table separating their chairs.

"Did you like it?" She asked, flipping her long black hair out of her face with her free hand. Blake struggled for words.

"I...I guess so? I just read some pages you...that you bookmarked," he replied, feeling awkward. Silvia giggled and blushed. "So far, those are my favorite pages," she admitted. "I guess you didn't know I read erotica," confessed Silvia. Blake shook his head. "Don't tell mom," she added. "She wouldn't like it." Blake laughed. "I Promise," he swore. His sister was so cool, he thought.

They talked into the night about the unanticipated new house and the amazing beach and lake. Silvia had loved the shops in the nearby town of Silverton. She wanted to go back tomorrow and walk around more. Blake realized that they had completely forgotten that they had a boat. They could ski, they could explore the whole lake for the first time.

The siblings beer buzz had worn off and was replaced by drowsiness from a long day. They cleared their dishes and empties from the porch and went inside. Blake's eyelids began to sink and he walked toward his bedroom still in his swim shorts. Silvia called to him. He turned around as she approached him.

"Thank you for helping, today," she said. Blake sighed. "You did the most," he admitted.

Silvia put her hand on his shoulder and kissed the corner of his mouth Briefly. She had kissed him many times in his life but this had seemed a little different. Never like that. They looked at each other confused.

Silvia put her arms around Blake's waist and again kissed him, but directly on the lips, holding her mouth open against his for several seconds, kissing him hard. Blake could feel the tip of her tongue inside of his mouth, he could hear the noise of their kiss and he pulled away. They stared at each other for a ten second eternity before going to their rooms for the night.

Silvia woke before Blake and drove into town for some coffee. She had forgotten to buy some yesterday. Blake, meanwhile woke and couldn't stop thinking about the boat. His dad taught him years ago how to operate It. There was a launch right next to the house and he backed it in with his truck and walked it over to the beach in front of the porch.

Silvia returned and sat on the porch with her coffee. "I bought you one," she said. Blake was tying off the boat to an anchor.

"You're really excited about the boat aren't you," Silvia noticed. Blake sat next to her and picked up his coffee, "Hell yes I am he said. Silvia looked at him and smiled.

"I have a great idea," she said. "Why don't I pack us a cooler of food and drinks and we can just hang out on the lake the rest of the day?" Blake smiled. "Twist my arm," he said.

All day they travelled around the lake. Blake and Silvia pulled each other half a dozen times on skis. There was a beautiful waterfall at the headwaters of the lake. Silvia wanted to swim by a small island at the bottom of it. Blake tied the boat off to a tree and ate some meat and cheese.

Silvia took her top off and dove in, swimming under the waterfall, letting the cool water fall over her hair. The day was hot, but it was only Wednesday and few other boats were on the lake. Silvia swam back to the boat.

"Jump in!" She said, splashing water onto Blake. Silvia hung onto to the back of the boat and pointed at the waterfall. "You have to see behind the waterfall." She floated away from the boat. Blake watched her breasts as she floated face up and disappeared under the falling water. Blake finished a Corona he was drinking and dove in.

He swam over to the falls and Silvia was not there. Behind the water there was a beautiful rock ledge. Below him, he felt a hand on his leg as his sister slowly surfaced in front of him. She stood in front of him in the chest deep water. "Isn't this cool?" She asked, gesturing to the stone feature. Blake nodded. "Yes, it's just like a bench," Blake noticed. Silvia wrapped her arms around his neck. He could feel her breasts against him. They looked at each other in the same confused way they had the night before.

Blake brought his face closer to hers. Again, Silvia brought her mouth against his and they began to kiss. Blake had no impulse to pull away this time. He kissed her back equally. Again he could taste his sister's tongue in his mouth but this time he offered his own in return. Minutes and minutes passed, all Blake heard was the sound of water. He began to Rub Silvia's firm breasts as they kissed, his hard cock was pressing his swimsuit against Silvia's tiny thong.

She softly pulled away from his mouth and began to kiss and delicately bite his neck. Her hand reached down his swimsuit and took hold of his erection. She moved her mouth to his ear, swirling her tongue inside of it.

"Can I please suck your cock?" She whispered, as she began to stroke him gently. "I want you to sit on the rock."

Blake adeptly leveraged himself onto the rock. He was so turned on. Silvia pulled off his swim trunks and rubbed her hands up and down his thighs. "This is ok?" She asked, looking down at his big erect cock. Blake breathed heavily, his brain clouded by the long sensual kiss his sister had given him.

He only nodded.

Silvia held onto his cock and began to suck his balls. One at a time she took his nuts into her mouth and sucked on them as she squeezed his shaft. Blake watched her and played with the long hair on the side of her face.

She began licking the bottom of his cock, kissing it and letting her saliva freely run over it. Blake was breathing hard. The skin of his cock was stretched so tight it began to hurt.

Silvia put the head of his cock in her mouth and as she did, she moaned in excitement. Blake watched her slip her right hand under the water and slide it down the front her bikini. She began to moan more intently and suck him harder, getting herself off to his cock.

Slowly Silvia moved his cock towards her throat. Blake leaned back on the rock in ecstasy. "Oh Sil, this is so amazing!" He exclaimed. She took him all the way into her throat until her mouth rested on top of his pelvis, moaning as she rubbed her clit.

Silvia began to ride his cock up and down with her mouth and throat, speeding up on each cycle. Blake began to groan heavily. "Oh Silvia, it's so good, so good!"

Soon she was ramming his cock as hard and as fast as she could from her lips to her tonsils. Silvia could start to feel his pre-cum run down her throat. She needed to scream. Taking her mouth off of Blake's cock, she began to stroke His spit-soaked slippery erection, slapping the head against her Tongue.

"I want to swallow your cum. I want all your fucking cum in my mouth!" She demanded. Silvia Jerked him off as hard as she could. Blake moaned loudly. He held Silvia's head as she jerked him off, slapping him against her tongue. His cum began to shoot rhythmically against the back of her mouth and fill it up. Silvia continued moaning, she swallowed all of it and again drove drove her lips down to his pelvis as she finished masturbating herself. Blake watched her with his mouth agape. She began to shake and quiver and she held his cock in her mouth several moments after each of them came.

Silvia continued kissing and loving on his cock until he began to go limp. "Blake, let me keep sucking your cock," she begged with a kind of sincerity Blake knew she could not fake. "I don't want this to be the only time."

"Yes please," he said.

As they drove the boat home. Blake thought about Silvia's incredible blow job. How peculiarly similar it was to the marked pages of her book. Carla was sucking Rick's cock in the same passionate way. He slowed the boat to a crawl.

"Are you copying the stuff in your book on me?" He asked, smiling as if in the midst of an epiphany. "That's exactly what Carla said in the book," Blake realized and he blurted out. "She said, 'I want all your fucking cum in my mouth!'" Silvia blushed.
