Samantha and Ethan rolled around on the couch kissing one another after Samantha's mother had gone to bed and their weekly television show had ended. Ethan was a boy from around the corner that Samantha had met through a friend of a friend. He was attractive, smart, and funny and she loved the way he kissed her with his slow, deep kisses.

She felt his hand climb up her shirt, stopping in places to stroke her skin and she let it continue for the first time without any protest, enjoying the electric sensation that rippled through her with every touch. Samantha felt his hard on through his shorts that poked her clothed pussy and was excited that he was as attracted to her as she was to him.

Ethan's hand reached her breasts and massaged her small tits over her bra. Her nipples reacted by stiffening and Ethan paid special attention to them.

Samantha wrapped her long, graceful runners legs around Ethan and moaned with delight. She felt his fingers pull down a cup of her bra and begin to stroke the bare flesh. Her breathing quickened and she gasped as he pinched and twisted a nipple.

"I love you, Sam," Ethan said between kisses.

"I know you do," Samantha said, enjoying the pressure of his cock against her.

The house creaked suddenly and Samantha stopped Ethan, pushing his hand out of her shirt while she listened for more sounds.

"Is everything okay," Ethan asked.

"I think we should stop for now," Samantha said reluctantly, wriggling out from under him.

"Sam," Ethan said. "It's just the house settling."

"I know," Samantha said as she readjusted her bra. "I just don't want to get caught. My mother would never let me see you again."

"Yeah," Ethan mumbled, clearly unhappy but accepting the reality of the situation. "No problem."

"I'll see you Monday though," Samantha said. "Right?"

"Of course," said Ethan, smiling his honest smile at her.

Samantha and Ethan stood and she leaned in to kiss him again, relishing his warm lips against hers. She then took him by the hand and led him to the door.

"Monday," he said, from the other side of the screen door. "If not sooner."

"I hope."

Samantha returned Ethan's smile and closed the door after him, leaning against it and bringing her hands to her breasts as she let out a deep sigh. She pulled on her nipples and made herself cry out quietly in the dark at the thought of him.

After her moment was over, she looked at the couch and realized that she had to make up her bed. Her mother had moved the family into a duplex after relocating and there were only two bedrooms. The master, of course, belonged to her mother, and the other used to be shared by Samantha and her twin brother Josh in bunk beds. It didn't take long for her to become uncomfortable sharing a room with him and soon she had the couch in the living room while he kept the bedroom.

Samantha opened the hall closet and pulled out her bedding. She placed a top and bottom sheet and then a comforter. In the dark, she striped off her t-shirt, shorts, bra, and panties and put on a pair of green cotton pajamas instead.

As she climbed into her makeshift bed, she knew from the wetness against her leg and the tingle in clit that Ethan had left her excited. She tried to ignore it at first and merely rubbed her small breasts but soon she realized that it wasn't going away. Almost shyly, she pushed a hand into her pajama bottoms and began stroking her naturally sandy blond bush. It was with the tips of her fingers at first that she tickled the top of her cunt.

Samantha thought of Ethan, running his fingers inside of her and her own reached deeper, stroking the nub of her clit. Her other hand unbuttoned her shirt and began a hard massage of her breasts as she felt the sensations from her pussy shoot first down her thighs and then up into the rest of her body. Her clit became more and more excited and grew and Samantha lost herself in the feeling. Before she knew it, the fingers of the hand on her breasts were in her wet and excited pussy. She could feel herself beginning to cum and the more she thought about the hardness of Ethan's cock inside her, the closer she felt herself to climax. The juices from her pussy streamed over her hand and Samantha bit her lip from the intense sensation of having her whole hand almost entirely inside of herself.

Just as she was about to go blind from her building orgasm, she heard a sound that she knew wasn't the house settling on its foundation. She looked up, towards the hallway, and saw Joshua standing with an erection in his boxer shorts that could be seen even in the dark.

"Jesus," Samantha nearly screamed from shock.

She pulled her hands out of her bottoms and sighed as the one left her pussy and looked up as Joshua.

"What the hell are you doing," she asked, half irritated that he interrupted her and half frightened of what he saw.

"I heard some noises," he said as he came over to her and sat on the couch beside her. "I just came out to see what they were."

Samantha realized that her breasts were uncovered and quickly pulled her pajama top back together.

"He really gets you worked up, huh," Ethan said.

"That's none of your business."

"I just thought I could help."

"I doubt it," Samantha said.

"I'm serious, Sam," he told his twin sister. "I could help you out and you could help me out."

"You're sick," Samantha said. She said it but didn't believe it. She could feel her bottoms beginning to soak with the juices that were still leaking out of her cunt. She had been so close to coming that she was willing to do anything to get back to it.

"No," Joshua said, as he put his hand down on the growing wet spot on her pajamas.

The sensation of a warm foreign hand on her sent shivers throughout her body and she could feel her nipples harden in response. She bit her lip to try and control herself.

"I'm not going to fuck you, Josh."

"I'm not asking you to," he replied. He took her hand and guided it to his body, sliding it down into his bottoms and around his cock. Samantha had never seen Ethan's and had no way to judge the size of her bother's but she was certain that it was bigger than the last time she had seen it.

Joshua pulled his bottoms down around his balls and Samantha stared at the cock of her twin brother that her hand was around.

"Just touch me like I touch you," he told her in a reassuring voice.

Samantha felt her brother's hand venture into her pajama bottoms and brush through her bush before sliding between the wet lips of her virgin cunt. Almost as if he had a map, his fingers settled on her clit and began tickling it back and forth.

Samantha inhaled sharply. The sensation was ten times what she could give herself. Dutifully she returned the favor, sliding her hand up and down the shaft of her brother's penis. She tried to forget the incestuous act she was committing and imagined that it was Ethan's cock she was holding and her hand bringing her to pleasure so quickly. She barely had time to see his face in her head before her body was wracked with orgasmic tremors that made her nearly shake off the couch. She nearly bit through her lip from the feeling while her free hand pushed Joshua's harder against her.

"Oh yeah, Sam," Joshua cooed. "Oh baby, keep going. Keep going."

Samantha tried to hold back a cry of pleasure but all she was able to do was mute it some. Joshua's fingers never stopped their rhythmic motion and as the first orgasm subsided she could feel as second building.

"Oh baby," Joshua moaned as her hand rose and fell against the sensitive skin of his penis. "Make me cum," he begged. "I want my sister to make me cum."

Joshua's words shattered the fragile illusion Samantha had created for herself and she opened her eyes to watch herself stroke her brother's baby maker. She looked up into his face and saw the pleasure he was giving her and instantly felt another jolt run through her body.

"That's it, Sam," Joshua moaned. "Make your brother cum."

Samantha's stroking grew faster and faster and his speed matched her own. The brother and sister found themselves in a race to see who would make the other cum first even though Joshua had obviously won round one.

"I'm coming baby," Joshua said as he leaned against his sister's shoulder.

"I'm coming too," Samantha cried.

Together they both exploded with pleasure and Joshua shot spurt after spurt of hot cum into his sister's hand and onto his belly. Samantha continued stroking Joshua's cock until every drop had been expelled and Joshua kept tickling his sister's clit until her violent tremors finally subsided.

"Oh my god," Joshua said with a sigh. "That was the most intense thing I've ever experienced."

Samantha looked down at her hand and realized that it was covered with her brother's sticky sperm. Her face contorted into a look of disgust as she leapt up and went to the kitchen to wash it off. When she returned, she found that Joshua was exactly where she had left him without moving a bit.

"That was disgusting and wrong," she said, buttoning her pajama top back up again.

"I know you don't think that's true," he said with a grin.

"Well, it doesn't matter because it won't ever happen again."

Joshua had returned the next night looking for more of what had happened before but Samantha held him off, telling him that she had never been so disgusted with herself. But the night after, when she found herself reaching for her pussy and her brother appeared, she let him do what he wanted.

Instead of sitting side by side and touching each other, Joshua put Samantha on her knees on the couch and pulled her bottoms down over her round athletic ass. He began by stroking his fingers through her cunt and she moaned with his every motion.

"Do you like that," Joshua asked her as he leaned down to kiss the flesh of her perfect white bottom.

"No," Samantha said, keeping her eyes closed and trying to imagine Ethan behind her instead of her twin brother.

"Don't lie to me, baby," Joshua said as he poked a finger into her increasingly wet hole. "Tell me you like it."

"I like it," Samantha said in a whisper.

"Tell me how much you like it," he said as he slipped another finger in.

"I like it a lot," she mumbled.

"Only a lot," he asked as he added a third. He leaned down and flicked his tongue across her asshole and she shuddered and moaned.

"I love it," Samantha said more forcefully.

"You love having your brother's finger you," Joshua asked.

"Yes," Samantha said, her head dropping in shame but unable to pull away from her brother's touch.

"Will you do what I ask if I make you cum," her brother asked.

"Yes," Samantha said, moaning as her twin brother's fingers pushed deeply into her tight pussy.

Joshua pushed his face into his sister's ass and began to lick like it was her cunt while he pushed deep into his sister's hot wet pussy with his three fingers. With his free hand he reached up to his sister's small breasts and toyed with her nipples until they hardened. He pinched and pulled at them and felt his cock grow harder each time his sister moaned in pleasure and pain.

Samantha felt her legs grow weak as the climax built in her and tried to brace herself against the arm of the couch. Her pussy felt tighter and more electric than it ever had before and she knew that staying up on her arms was a useless effort. She dropped her face against the arm of the couch and used her free hand to guide her brother's exploration of her tits. She moved him to a nipple he had been neglecting and pushed his fingers hard against her nipples. The pain was almost too much to bear but the pleasure it gave caused her body to ripple through with an orgasm like she had never had before. Her brother's tongue breeched her asshole and his fingers pushed against her cervix. She felt almost like an animal as she humped back at him, harder and harder each time. She screamed as she came into the padding of the arm rest, sure that it would muffle at least some of the sound.

Joshua gave his sister a moment to rest before pulling his rock hard baby maker out for his sister. Samantha looked up from the arm of the couch, her naked ass still trembling in the air.

"What do you want me to do," she asked cautiously.

"I want you to take me in your mouth," he said.

Joshua stood in front of his sister and Samantha slowly righted herself, reaching out for his cock with her hand. She pulled it towards her mouth. At first she just licked the head, finding herself afraid and a little bit disgusted with herself for tasting her twin brother's penis. But as she heard Joshua moan, she grew more aggressive.

Samantha began to kiss his hard pink pole and slowly drew it into her mouth. She wrapped her lips around the purple head and tickled the underside with her tongue, tasting the pre-cum that leaked from the tip. The salty, slick fluid made her want more and she began to suck on her brother's cock like a tootsie pop.

Joshua pushed his baby maker deeper into his sister's mouth and moaned as her tongue slid along the sensitive underside. He watched his sisters sweet lips take him inside and grew so hard he thought he would burst as he saw the lust she had for him in her eyes. He pulled himself back out so her lips were wrapped around only his head again and then pushed back in.

He reached down and took the small handful of a tit in his hand, pushing and squeezing it and feeling the vibrations of her moan travel up his pulsating cock. Joshua loved seeing his sister half out of her pajamas sucking him off.

"I belong in your mouth, baby," he said as the pressure began to build up in his balls. "I'm going to cum," he moaned to her. "I want you to swallow every drop."

Samantha moaned at the thought of it and licked and sucked him harder, driving up and down her brother's shaft. The pre-cum began pouring out onto her tongue. Her hand drifted down to her cunt and she started rubbing herself, up and down her slit as she anticipated the load Joshua was going to leave in her mouth.

"Faster," Joshua moaned as he began to fuck her face. "Suck your brother faster, baby."

Like a lightening bolt from his balls, Joshua erupted into an orgasm, spewing rope after rope of hot, sticky cum into his sister's mouth. Samantha sucked it down hungrily and stroked her clit harder and harder until she too began to cum. She refused to let her brother's cock leave her mouth and sucked as her body leapt with orgasmic tremors.

Joshua could hardly stand and held onto Samantha's small shoulders for support until she finally released him from her semen filled mouth. He collapsed onto the couch next to her and the brother and sister held each other while they recovered from the experience.

Samantha could still taste her brother in her mouth as he turned over and began to suck on each of her nipples. She struggled to push him away from her, still too weak to stand up herself.

"You'll eat my cum but you won't let me kiss you," Joshua asked, letting himself be pushed away.

"This is gross, what we're doing, Josh," she said, pulling her pajamas back up and her shirt closed. "A brother and sister aren't supposed to do this."

"I know you're turned on by it," he said, putting a hand on her strong, athletic leg and squeezing it. "You can't deny that."

"Maybe," she said, closing her eyes and refusing to look at her brother. "But that doesn't mean it's right."

Right or wrong, Samantha found herself unable to refuse her brother's attentions each time he came to her over the next two weeks. Some nights they only stroked each other while some went as far as being completely nude together and pleasuring each other with a sixty-nine. Her protestations lessened and soon she found herself calling his name when he touched her.

She continued to see Ethan but began to grow bored with him, waiting instead for him to leave so she could be with her twin brother. Each morning, she awoke feeling sore or tasting him and felt guilty and sick with herself the whole next day but couldn't stop herself from wanting him even more the next night. When he wasn't around, she masturbated to the thought of Joshua and imagined his cock back in her mouth where it obviously seemed to belong.

After two weeks of it, Joshua again had Samantha on her knees while he fingered her wet and steamy pussy.

"I love it, Josh," she moaned between her desperate panting. "I want more."

Josh had his cock out and was stroking it while fingering her and leaned down to kiss her lower back.

"I want to give you more, Sam," Joshua said.

He gently pulled his fingers out of her hole and listened to her cry out in disappointment as he stroked the nub of her clit with her own wetness. He moved closer to her and positioned his cock against her desperate pussy. Very slowly, he began to slide his baby maker into his sister and listened to her gasp as she felt herself fill up again.

"I've been wanting to be inside you since the first night," Joshua said as he slid in as far as he could. He pushed against her cervix and watched as her body jerked from the slight pain and intense pleasure it gave her.

"Are you," Samantha asked. "Are you fucking me?"

"Uh huh," Joshua said as he leaned over her and cupped her breasts from underneath. He pulled his cock back out so that only the tip remained, parting the lips of her pussy. "Do you want me to keep going?"

"Please," she begged.

"You want to be fucked by your brother?"

"I want you deep inside me," she panted.

That was all Joshua needed to plunge his rod back into his twin sister and watch as she bucked under him. Samantha pushed back and humped his cock with as much desire as he drove it into her.

The excitement of being fucked by her brother drove her wild and she felt herself beginning to cum. The grabbed her brother's hands and pushed them tightly against her breasts and she moaned into the pillow with wild passion while her brother's cock pumped in and out of her pussy.

"I'm cumming, Josh," she cried.

"I'm going to cum soon too," Joshua said, grunting as he drilled deeper his flesh and blood. He felt the familiar pressure build up in his balls and considered for a moment what it would mean to cum inside his sister's tight vagina. "I'm going to cum inside of you, Sam."

"I want you to," she said, slamming her ass back against Joshua's hips, faster and faster. "I want to feel you inside me all night and tomorrow."

The permission from Samantha to cum inside of her unleashed Joshua's desires and he jerked as his balls opened up with splash after splash of baby making sperm deep into his sister's fertile young womb. He pushed his cock as deep into her as he could to ensure that not a drop would fall out and felt the muscles of his sister's pussy milked his rod for more.

His penis began to shrink and Joshua pulled out of Samantha and watched as her pussy tightened and closed after he was gone. Samantha stayed where she was, her naked hips and ass still in the cold air of the living room while her brother slumped next to her. She collapsed into his arms and enjoyed the slow gentle massage of her tits while the two of them breathed in rhythm.

"Don't tell me you feel guilty about that," Joshua said, expecting to hear his sister's usual protestations.

"Not at all," she sighed, satisfied.

He kissed the back of her neck and moved a hand down to strike her thigh.

"I want you to move back into the bedroom with me," he whispered quietly. "We should sleep together every night."

Samantha flipped over in Joshua's arms and kissed him on the lips for the first time ever. "You want me every night," she asked.

"Every night," he said.

The night after she moved into her brother's room, Samantha told Ethan that she was no longer interested in seeing him. She told him that she was with someone else but left out that it was her twin brother. Within a month she knew that she was pregnant with Joshua's baby. The sibling's sex life only grew stronger after she told him. He obsessed over her growing belly and widening hips. She dropped out of school in their senior year, a month before she gave birth to their first son. Afterwards he loved her larger, heavier milking breasts. By the time Joshua went to the local junior college, she was pregnant with a daughter.

Their mother never said anything about her daughter's pregnancies or asked about the father and Joshua and Samantha never tried to hide it from her after Samantha began to show. Instead she took care of her grandchildren while her son continued to breed her daughter over and over again.
