Decisions: 02

When we last saw the Family, they were in the midst of making a decision. The decision they made resulted in Lucy being fucked and knocked up by her Cousin Mark. But what if the decision had gone a different direction?

The Decision

"I don't mind if Mark sleeps with me," Lucy said. "It's not like he's some strange boy. Mark is my cousin."

Mandy groaned in disgust. "I'll sleep downstairs with Mark. Lucy shouldn't have to sleep in the same bed as my Brother."

"I really don't mind," Lucy replied calmly.

"I know you don't. But he's my Brother which means it's my problem. And I'm not shoving my problem off on you. You sleep with your Mom, and I will sleep with my Brother."

Mandy soon crawled into bed dressed in her sleeping shirt, and panties.

Mark was dressed only in his loose fitting sleeping shorts.

"I hope you don't hog the covers," Mandy scowled as she rolled over on her side with her back to her Brother.

"Don't worry," Mark replied. "I don't toss and turn in my sleep."

"No, you just walk in your sleep."

"I haven't walked in my sleep in years," Mark growled.

"I hope you don't do it tonight."

Before long, both Brother and sister had settled in for the night and were sound asleep.

As the night wore on, Mandy and Mark tossed and turned in their sleep. By three am Brother and Sister were in a blissful spooning position with Mandy's round panty covered buttocks pressing against Mark's cock.

As the sleeping pair snuggled against each other Mark's dick began to become erect. His manhood stretched the material of his sleeping shorts, and slipped out the waistband of his shorts. As his erection grew, the head snaked under Mandy's shirt.

Feeling the bare meat touching her back, the sleeping Mandy subconsciously turned over to face her brother.

Mark's cock was soon pressed against Mandy's stomach.

The two subconsciously snuggled closer to one another.

Mark wrapped his free arm around his sister, and drew her close.

The pretty Sister began to gradually wake up. She was confused at first, but soon the memory of why her Brother was in bed with her came back to her half sleeping mind.

"Mark, move over onto your side of the bed," she mumbled, struggling to return to a state of unconsciousness.

Mark moaned in his sleep, and pressed tighter against his sister.

Mandy felt the throbbing monster rub up against her stomach. Her mind instantly became alert and her eyes popped open. Mandy realized that her Brother's cock had gotten hard and had somehow escaped his shorts.

His throbbing member was rubbing up against her bare stomach.

"Oh shit," Mandy whispered fearfully. She knew that if Mark woke up while they were in this position they would both be mortified by this experience.

Mark pressed his dick tighter against his Sister's stomach and moaned in pleasure.

"Great," Mandy seethed. "My fucking Brother is a pervert even in his sleep."

Mark began to thrust and grind against his sister, moaning and muttering with each small thrust.

"What is he doing?" Mandy whimpered.

Mark began to rub the length of his cock along Mandy's pelvis and stomach.

Mandy felt a wave of revulsion pass through her. She couldn't believe her sleeping Brother was dry humping her. She was also shocked at just how big her Brother's dick was.

The sleeping young man slid his other arm beneath his Sister's side, and pulled her even closer to him. He continued to moan and grind against her body.

Unable to take it any longer, Mandy leaned her lips close to Mark's left ear. "Mark, wake up," Mandy whispered.

The dreaming young man suddenly turned his face, and pressed his lips to his sister's mouth.

Before Mandy could stop him, she felt her Brother's tongue slip between her lips. She could feel his tongue dancing around in her mouth. Mandy suddenly realized that Mark wasn't just sleeping. He was in a state of sleep walking, something he hadn't done since he was a child. Mandy remembered the stories she'd heard about sleep walkers becoming violent when awakened unexpectedly.

Mark continued to grind his cock against his sister's body as he kissed her mouth.

Mandy whimpered as her Brother rubbed his huge cock back and forth against her pelvis and stomach. Mandy knew she had to get him to let go of her without waking him.

As Mark rubbed against his Sister, his sleeping shorts began to slip off his hips. Soon his entire erection was free, and pressing against Mandy's body.

Mandy wanted to cry out, but the thought of being found like this was even more terrifying than having her Brother wake up while they were in this position.

Mark continued to thrust against his Sister's body. His sleeping mind was enjoying the dream tremendously. He suddenly rolled over, taking his Sister with him, so that she was lying on her back, with her Brother on top of her.

Mark had slid his legs between his sister's thighs. He held part of his weight off Mandy with one hand, but still he kept enough weight on her to keep her pinned to the bed.

Mandy gasped in disbelief. She realized that her sleep walking Brother was positioning her for sex. Mandy then remembered the special she'd seen on television about sleep sex. She remembered that people who had sleep sex were not consciously aware of their actions. Mandy had no doubt that Mark was just carrying out what his subconscious told him to do. But still, the thought of being violated her Brother made the young woman feel queasy.

Mark pressed his lips against his Sister's lips once again. He kissed her furiously, forcing his tongue deep into her mouth. He began to run his fingers through his Sister's strawberry blond hair. He ground his huge cock against his Sister's panty covered clit.

Mandy involuntarily moaned into her Brother's mouth. She couldn't believe her sleepwalking Brother was trying to fuck her. To make matters worse, she couldn't believe her body was beginning to respond to her Brother's sexual advances.

Forcing her face to the side, Mandy once again whispered into her Brother's ear. "Mark, you have to wake up. You can't have sex with me. This is incest. Besides, I'm not on birth control. I could get pregnant."

Mark reached between his Sister's legs and grasped his monster. He began to rub the head of his cock against the gusset of Mandy's panties.

The feel of his cock head rubbing against her clit, caused Mandy to involuntarily moan again. Her legs drew up at an angle, tilting her pussy to a more inviting position.

"What am I doing?" Mandy exclaimed. She couldn't believe she'd just opened herself up to her Brother's touches.

Mark began to rub the head of his monster along the length of her panties.

Mandy's body began to tremble with desire. Her mind told her that this was wrong, but her body screamed that this felt all too right.

Yes, Mark is her Brother. Yes if he fucked her without protection, disastrous consequences could occur.

But the head of that beast felt so good against Mandy's pussy.

"Mark, please wake up," Mandy whispered. Her voice could barely be heard.

The sleeping young man suddenly released his grip on his shaft. Slipping from between his sister's thighs, he took hold of the waistband of Mandy's panties and pulled.

Mandy gasped as the panties were tugged off her rounded hips, and down her long legs. She was completely unprotected. Her neatly trimmed snatch was exposed and ready for use.

Before Mandy had a chance to think about the fact that she was free, Mark climbed back onto his Sister, and forced his legs between hers.

Once again Mandy was helpless beneath her Brother.

In his state of sleep sex, Mark could easily thrust his monster into her pussy and she would be unable to stop him.

"Mark, listen to me. We can't do this. We can't have sex. It's wrong."

The sleeping man once again grasped his manhood. Positioning it against the entrance to her sex, Mark began to rub it back and forth through the folds of her vaginal lips.

Mandy whimpered as her Brother's cock head began to run back and forth through her pussy lips. Another terrible thought ran through her mind. Mandy had never taken a cock this big before. Even her dildo was smaller than Mark's cock.

Mark would split her wide open if he forced his cock into her with one thrust.

Doing the only thing she knew to do, Mandy leaned up and whispered into her Brother's ear again. "Be gentle, baby. I've never had a cock as big as yours before."

Mandy could only hope that her message got through to her Brother's subconscious and he'd fuck her slowly and gently.

Mark eased his cock forward a couple of inches.

Mandy whimpered as she felt the head of her Brother's cock slip into the entrance of her lubricated vagina.

The sleeping young man eased the tip back a half inch, and then pushed forward again.

Mandy's body tensed as she felt the entire head and an inch of his shaft slide into her body. "That's it Darling," she whispered. "Go slow."

Mandy knew she was going to be fucked and there was nothing she could do about it. Mandy also knew that Mark wasn't trying to rape her. He was simply having sleep sex, and her body happened to be near by. Knowing that she had no choice in this matter, Mandy once again raised her knees, spread her legs wider, and trusted that her Brother wouldn't hurt her too much with his huge cock. She just hoped that this little sexual encounter didn't lead to her becoming pregnant.

Mark pressed his cock deeper into his Sister's body.

Mandy gritted her teeth as she felt the walls of her pussy stretching to accommodate her Brother's dick.

Mark was taking his time, but even with the slow penetration, Mandy felt like she was being stretched beyond endurance. Tiny pricks of pain shot through Mandy's pussy as it slowly stretched open for her Brother's monster cock.

"Oh fuck, your cock is too big," she moaned. "You'll split me in half with that beast."

As Mark worked six inches of his dick into his Sister's body, he leaned close, and placed his mouth next to her right ear. "Don't worry Sis, being twins our sex organs were made for each other. I guarantee that every inch of my cock will fit perfectly in your pussy."

Mandy's face showed the shock she was feeling. Her twin Brother was awake. He was awake and knowingly fucking her.

"What the hell are you doing?" She asked in disbelief.

Mark tilted his face up and gazed into his sister's lovely eyes. A naughty grin crossed his handsome features. "I'm making love to my sexy twin sister." Mark drew back and thrust forward.

Mandy whimpered as another inch of his cock sank into her depths. "Mark, I'm your Sister. You aren't supposed to fuck me."

"Mandy, you're my twin sister. We were made to fuck. We were made to be together. We came from Mom's womb just two minutes apart. My cock was made for your pussy, Darling. I love you."

Mark withdrew part way before thrusting back into Mandy's already stretched pussy.

Mandy moaned deeply. It wasn't just a moan of pain. The pleasure she felt shot through her nether region like a bolt of lightning. Her Brother's wonderful cock was causing her to experience pain and pleasure like never before.

"This is so wrong. We aren't supposed to be fucking. Mark we're committing incest."

Mark thrust into his Sister again. "We're making love, my Darling Sister."

She wrapped her legs around her Brother's hips and squeezed.

His cock sank deeper into her trembling body.

Mandy's mind began to spin with confusion. She knew that what they were doing was taboo. But the feel of her Brother's cock in her wet pussy felt incredible.

"Oh my beautiful Brother that feels so wonderful. I can feel your dick deep inside me. Please Mark, I know it's wrong, but fuck your Sister harder." Mandy couldn't believe she'd just said that.

Mark drew his cock back to the very entrance of his sister's open pussy. He gazed deeply into his Sister's eyes.

Knowing what her Brother was about to do, Mandy sucked in a lung full of air, and then bit down on her lower lip. She slid her arms around her Brother's neck and held on for dear life. She tightened her legs around her Brother's hips.

"I'm ready Darling. Ram it all the way in."

Mark tensed his hips for a moment, and then thrust his monster deep into his Sister's body.

Mandy bit down hard on her lower lip as her Brother's cock opened her up the rest of the way. She whimpered in pain and pleasure as his cock head slammed into her cervix wall.

"Oh fuck, you're all the way in me," Mandy exclaimed.

"I do love you Sis." Mark began to ram his cock into his sister's willing body.

Mandy gripped her Brother's neck and hips tightly as he pounded into her again and again. "I love you too Darling. Oh, you feel so wonderful inside me."

Mark's thrusts were long and deep. With each withdraw of his cock Mark left his sister's pussy feeling empty and alone. But each return thrust filled her body, and made her feel loved and needed.

"Oh Mark, I love your big cock in my pussy. I love having my Brother's cock buried in me."

Mark thrust again and again into his Sister. He could feel her body preparing for orgasm. He knew she would cum in a few minutes. An evil smile crossed his lips. He would also cum. He would plant his rich, potent seed deep in his Sister's body.

Mandy would carry her Brother's child.

The family would be horrified.

But Mark didn't care. He would have his sister as his Wife until death do they part.

Mandy's body began to tremble and shake as her orgasm continued to build. "Oh fuck, I'm going to cum."

"I'm going to cum with you Darling," Mark whispered into her ear. "I'm going to cum into your unprotected pussy."

"Mark if you cum in me, you'll make me pregnant."

"Yes, I will knock my beautiful Sister up. I will give her my baby, and we will spend the rest our lives together making love, and making babies."

Mark picked up his pace. He thrust harder and harder into his sister's body.

Mandy knew that it would be crazy to let her Brother make her pregnant. But at that moment she didn't care. She wanted to feel her brother's baby batter spray all over the walls of her pussy. She wanted the sperm to make a mad dash for her eggs. Mandy realized that she wanted her Brother to make her pregnant. Mandy wanted to have Mark's children.

Mark's balls churned with a new urgency as his cock slid in and out of his Sister's body again and again.

"Oh Darling," I'm about to cum," Mandy breathlessly exclaimed. "Oh fuck."

Mandy tightened her grip on her Brother's hips, forcing him deep into her stretched out pussy. She clung to his neck. Her orgasm was going to be intense. When it hit, her pussy muscles clamped down on her Brother's swollen cock and began to milk it for the precious life giving sperm.

Mark couldn't control himself any longer. He groaned deeply and let his sperm fly into his Sister's womb.

Brother and Sister rocked together as their orgasms shook the bed.

"You're knocking me up Mark," Mandy snarled through gritted teeth. "Oh fuck, my Brother is knocking me up. My twin Brother is giving me a baby."

As the lovers ground together, their Mother, and Aunt stood outside the door listening. The Sisters were frantically rubbing each other's pussies as they pressed their ears to the door.

Sarah smiled at her older Sister. "If I'd slept with Mark tonight instead of Mandy that would be me in there getting knocked up right now," she whispered.

Carol smiled at her younger Sister. "It could have been me being knocked up by my Son instead."

Sarah gazed lovingly into her Sister's eyes. "Would you really let your Son fuck you, and make you pregnant?"

"I've let you eat my pussy all these years, Sister." As the first wave of her orgasm hit her, Carol gave her beautiful Sister a knowing smile. "Oh fuck I want to feel your tongue buried in my pussy so bad right now."

Decisions can make a difference in our lives. We go let, we go right. One simple choice can affect the rest of our lives.

Mandy did indeed become pregnant by her Brother. Mark and Mandy moved away, and lived as Husband and Wife.

Their Father was heart broken by the whole ordeal at first. He eventually accepted it, but it was very difficult for him.

But their Mother and Aunt Sarah knew what the joy of incest could do for siblings.

Yes, when they were much younger, Carol, and Sarah had made a decision that affected how they saw each other. They became lovers. And even though each Sister had met a man, and become a Wife and Mother, the love and lust they felt for one another never died. That's why to this day they get together every year in the guise of a vacation. And while the rest of the Family is sleeping peacefully, the Sisters slip off together and make mad passionate love.

Mandy's decision did have consequences that stayed with her for the rest of her life.

But what if another member of the Family had slept with Mark that night? What would have been the results of that decision?
