Sheltered Siblings Part 3

Greg and Penny explore their desires and their lives will forever change.

Greg and Penny had decided to take a shower after their last session. Penny took her time exploring every inch of Greg’s body as she washed him. When it was Greg’s time to wash Penny he took his time as he explored every inch of Penny’s body. By the time that they were done they both trembled with excitement.

After their shower they fixed their dinner and sat naked as they ate. They recalled how all of this started with Greg finding a magazine. After cleaning the kitchen Penny ran out to the barn to retrieve the magazine. She brought it into the living room and sat down next to Greg. She opened it up and began to look through it to see what other things that they could try.

There was a set of pictures that showed a man fucking a woman in her ass. Another one where a woman was sitting on a guys face and then moved to his cock. At one point she was facing him but then she was turned around with here back to him. There was one where a woman was on her back with her head hanging over the side of the bed as a guy fucked her mouth and later ended in a 69.

There were also captions that described some of the activities that were pictured. They learned that Greg’s thing was called a cock and balls. They also learned that Penny had a pussy and tits. Also they both had an asshole.

Penny wanted to try everything that she saw in the magazine. “Greg I think that we should take this to your room and do all of these things. I don’t want to miss anything!”

“Penny are you sure that you want me to put my cock in your asshole?” Greg inquired. “I want to experience everything Greg and that means at least try everything. If I don’t like it then we don’t have to do it again.” Penny said.

So they both went into his bedroom and Greg told Penny to lay down on the bed. After she laid down Greg crawled onto the bed on his hands and knees and straddled her body. He leaned down and began to kiss her tenderly and passionately. After a few minutes of intense kissing he slowly worked his way down her chin and neck as he kissed, licked and nibbled. She was breathing heavily and whimpering as he continued across her shoulders and down to her tits.

He worked his way around each one up to each nipple. He took each one into his mouth as he sucked on them. She thrust her chest up trying to get more of her tits into his mouth. She moaned as he continued lower across her stomach to her belly button. He shoved his tongue inside and swirled it around. Penny trembled and grabbed handfuls of his hair.

She guided his mouth down to her soaking wet pussy as he kissed across the swollen lips. She was so worked up from his trip down her body that she came instantly. She gasped loudly as her orgasm washed over her body. Greg lapped up her nectar as it flowed from her quaking pussy.

He shoved his tongue deep into her pussy as she pushed herself against his mouth. She ground her pussy all over his face and coated him in her juices.

“Yessss I love when you eat my pussy. Your tongue feels so good!” She moaned.

He doubled his efforts as he ate her pussy like a starving animal. She came over and over again as he swallowed her juices. She finally pushed his face away because she had become too sensitive for him to continue.

“Your turn now!” She said as she moved around on the bed with her head hanging over the side. “Fuck my mouth like in the magazine!”

Greg climbed off the bed and walked over to where her head was. Penny grabbed his hard cock and pulled it into her mouth. Greg reached down and grabbed her tits as he began to thrust into her mouth. Getting deeper with every thrust until she was taking it down her throat and his balls slapped her face. She reached down and shoved her fingers into her soaking wet pussy.

She moaned around his cock as he continued to drive balls deep. Penny loved the way his cock felt in her mouth and throat. She was born a cock sucker and didn’t even know it. Greg pulled and twisted her nipples causing them to stand up proudly.

Penny swirled her tongue around his cock as it slid in and out of her mouth. She loved the response she got when she swallowed as his cock stretched her throat. Everything that they did together just seemed right. They didn’t care that they were brother and sister. They were lost in their own desires and they were happy.

Greg pulled his cock from her mouth coated with her slobber and his pre cum. “I want to feel my cock in your asshole Penny!” Greg groaned.

Penny quickly flipped over with her knees at the edge of the bed with her legs spread just enough to put her asshole level with Greg’s cock. She laid her head down onto the bed and looked at him. “Fuck my ass Greg!” She whimpered as she wiggled her ass.

Greg took his wet cock and placed the head at her tight little asshole. He slowly pushed against her rosebud and she tensed up for a moment at first because it was a strange sensation. She then relaxed and then the head popped into her virgin asshole. She gasped loudly as her ass stretched to accommodate his cock. He stopped and said “Are you OK Penny?”

“Yessss but hold on for a moment! I need to get used to this!” She responded. It was painful at first but it also felt amazingly different from his cock in her pussy. She knew that she was going to enjoy it as soon as she could take it all.

She slowly pushed herself onto his cock as she felt it slide deeper into her ass. It seemed to go on forever. It felt like he would come out of her mouth any minute now. Soon she felt his balls resting against her pussy and heard Greg groan loudly and deeply.

She waited for a few minutes and then said “OK Greg fuck my ass now!” Greg grabbed her hips and began to slide in and out of her tight little ass. She moaned and whimpered as she gave over to the pleasure that coursed through her body. Greg loved the way her ass milked the entire shaft of his cock.

It was hotter and tighter than her pussy and he immediately knew that this was a better place for his cock. Penny wondered if there was anything that was in the magazine that she wouldn’t like. Right now everything they had tried felt amazing to her. She loved the way his cock felt as he drove it into her mouth, pussy and ass.

“YES YES YES YES YES YES YES YES!” She chanted every time his balls slapped her pussy. Greg thrust forward as she slammed back driving him as deep as possible. They both trembled with excitement and anticipation as their bodies slapped together.

“This feels amazing Penny! I am glad that we tried it!” Greg grunted as he felt his cock ready to explode into her ass. Penny was in the throws of another orgasm as she felt his cock expand and she felt his cum as it splashed her insides.

“I CAN FEEL IT! I CAN FEEL YOU FILLING ME!” Penny screamed as Greg emptied his incestuous seed deep into her ass. They both collapsed flat onto the bed together. Greg laid on her back with his cock still buried in her ass.

“I definitely want to do that again!” Penny gasped as she felt his cock throb once more.

“Absolutely we will definitely be doing that again!” Greg groaned as his cock slipped out of her ass.

Greg slid off her back and laid beside her and cuddled as they both fell asleep. When Greg woke up the next morning Penny was in the shower. Greg got up and went to take a piss. He could see her outline in the shower. Penny heard him enter the bathroom and his piss hitting the water.

“Care to join me in the shower lover?” Penny inquired as she opened the shower door and revealed her wet naked body to his gaze. Greg immediately stepped in and they kissed deeply. She washed him and paid special attention to his cock and balls. After she rinsed him off she wrapped her arms around his neck and pulled herself up as she wrapped her legs around his waist.

Greg placed her legs over his arms and pushed her back against the shower wall as he drove his tongue deep into her mouth. Penny moaned as she sucked on his tongue and ground her pussy against his stomach. Greg aligned his cock up with her pussy and slid her down onto his shaft.

He began to drive balls deep into her pussy as ass bounced off the wall. She chanted “FUCK ME FUCK ME FUCK ME!” As Greg attacked her nipples with his mouth. They fucked like rabbits in heat and they didn’t have a care in the world.

At that moment the only thing that mattered was the pleasure that they both felt as his cock slammed into her pussy. Penny would let Greg do anything that he wanted to her. She would accept his cock into any of her holes at any time and any place. She belonged to him and he belonged to her.

His cock was a drug that she was addicted to. She had to have a fix every chance she could. She loved the way it felt as it slammed into her body. From the veins rippled along the shaft to the big plum sized head. It fit and filled her perfectly in every way possible.

She came hard as he continued to pound her pussy. She bit his shoulder as her ass slapped against the wall. He grunted as he shot a massive load into her womb flooding her insides. The only thing that mattered was his cock filling her pussy.

They both saw starts as they came together. Greg kept his cock buried to the balls in her pussy until it had deflated and slipped out. His cum mixed with her juices plopped onto the shower floor and washed down the drain except for some that remained inside. Unknown to either one of them it was fertilizing one of her eggs at that moment.

Penny was now pregnant with Greg’s child. She would soon become a mother. But it would be a little while before they understood that their lives were about to change drastically.
