Nathan and Becca mg, mgg, gg, mb, inc, 1st Nathan always enjoyed it when his sister had a sleep over with her friends. The thirteen-year-old boy always had a crush on his ten-year-old sister's friends. Nathan and Becca had the two basement bedrooms and the parents trusted them to stay out of trouble. This night, she had two sisters over. Mia was eleven while Nina was nine. They lived down the street and Nathan found both of them very cute. The girls had all gone into the bathroom and gotten ready for bed so after they were done, Nathan chose that time to take his shower and get ready for bed. He walked back to his room in just his towel and saw Mia under the covers in his bed. "What are you doing in my room?" Nathan asked. "Waiting for you." she answered, pulling her nightgown she had hidden under the sheets to indicate that she was naked. "Can't I stay?" "What about Becca? Nathan said nervously. "We talked and I told her that I wanted to have sex with you. She and Nina dared me to try so here I am." She slowly pulled the sheets down, revealing her nipples, two slight mounds emerging from her chest. "You seriously want to have sex with me?" Nathan asked in nervous and excited disbelief as he slowly walked over to his bed. "Yes." she said as he sat down on the edge of his bed. "There is only so much girls can do with each other." She was pulling apart his towel to reveal his naked waist and young teen cock that was erect at the discussion by this nymphet. She also pulled the sheets down to reveal her entire naked body as Nathan stared at her hairless pussy. "Come on." she said, patting the bed next to her. Nathan moved to her and laid down. Immediately, the two were kissing with a youthful lust of two who were planning to lose their virginity to each other. He could tell she had practiced kissing before and then realized what she meant about two girls doing so much with each other. That made him hotter thinking of Mia kissing and doing other things with his sister. Suddenly, he heard some whispers and muffled giggling from the door. "Just come in, you two." he said. Becca and Nina entered the room with smiles. It had been a while since Becca had seen her brother naked, but he wasn't even trying to hide. "So you two want to watch me have sex with Mia?" Nathan asked the two. "Yeah." Becca answered for both of them. "Have you girls ever done stuff with each other?" "Yes." Becca blushed. "If you want to watch us, then I want to watch you and Nina have fun with each other as well." Nathan said. "Get naked like us and show me what you girls like doing with each other." Quickly the girls got naked and started to kiss each other. It was very hot watching his naked sister and her friend kissing. He'd never thought as Becca as a sexual prospect before, but now watching her act so sexual toward her best friend, everything was changing. "Hey Becca! Come over her and give your brother a kiss before we have sex." Mia said with a grin. Becca walked over to her brother. "Do you want to kiss me?" she asked with twinkle in her eye "Sure." Nathan answered nervously. He knew they were going to cross a line that siblings shouldn't cross, but also knew he wanted to break through that line. He sat up on the side of the bed and brought Becca between his legs and right up to him. They met their lips, the more experienced Becca leading her brother in a kiss of lovers. "I want to do more than kiss you, Nate!" Becca told him after their kiss. "But later." She then turned to Nina. "Kiss my brother before your sister has sex with him." Nina eagerly went up to replace Becca and soon was kissing Nathan with as much expertise as her sister and his sister. Nina suddenly gasped in mid kiss. Nathan looked down and watched as his sister was reaching between Nina's legs and playing with her pussy. They ended the kiss when Mia split them up to kiss him once more. "Let's get back to business." Mia seductively said. She laid down on the bed, dragging Nathan on top of her. They were in position. Mia spread her legs apart as Nathan's cock was touching her virgin lips. "Do it!" Mia ordered. Nathan looked over at his sister and her friend for a second before pushing his cock into Mia's pussy. It was tight, but he slid in just past the head of his cock. He gasped at the feeling and Mia just moaned softly. "Go on, Nathan. You are so big but so good!" Gradually, he pushed more of his cock into her pussy. She had lost her hymen to her sex play, so there was no barrier for his cock. He didn't stop until he was completely buried in Mia's body. He groaned at the feeling of his cock inside of this young girl. Mia likewise couldn't believe how astonishing a cock felt in her pussy. The other two girls were watching with amazement and a little jealousy, both wishing they were in Mia's place. "How does it feel?" Nathan asked Mia, slightly concerned. "It feels so great!" Mia replied back with a deep lustful look in her eyes. He leaned down and gave her a kiss. She reciprocated with a passion reserved for the first boy to take her virginity. Nature took over and he moved out of her pussy before pushing back in. Both moaned with pleasure at the sensations. He repeated his motions, pulling out more on each stroke. The other two girls were watching with amazement as their siblings had sex with each other. They were just sitting and playing with each other's pussies while watching the sex on the bed. Nate looked over at them and nearly lost it. "Come over here, you two." he said to the girls. "I want to finger you, Becca." The girls eagerly went over to the bed and Becca climbed on the other side where there was room to kneel up on the bed. She leaned down and kissed Mia on the lips even as her brother's cock was riding in and out of her. Becca than moved up to kiss her brother on the lips as well. He reached down and cupped his hand on his sister's pussy. He couldn't believe how it felt or that he was actually touching his sister like this. He was even more surprised when Mia had her sister sit on her face. Nina squatted over her sister's face so that her pussy was at Mia's mouth. He watched as Mia, the girl he was having sex with was licking her sister's pussy out. Nina was facing him with a big grin on her face. Nathan leaned over and kissed Nina on the lips. "Switch with me, Becca." Nita said. She got up and moved off her sister to allow for Becca to plant her pussy on Mia's mouth. Nathan couldn't believe how hot it was to have the person who was tonguing his sister's pussy be the same person he was having sex with at the same time. Just as he had done with Nina, he kissed his sister as she knelt there getting a good licking. It was too much for him. He felt himself feeling at his best ever. His orgasm was washing over his body as he shoved his cock deep into Mia's pussy and shot his virgin load into the preteen girl's formerly virgin cunny. He let her know and moaned as his sperm shot from his cock into Mia. Mia also moaned, but her voice was muffled by Becca's pussy. Becca moved and watched as her best friend was cumming hard. "Yeah Nathan!" she called out as her orgasm electrified her body even better than the ones her sister or Becca had given her. She felt as Nathan's cum shot into her pussy with such force and her own pussy muscles were grasping at his cock with sexual abandon. "Oh!" Nathan couldn't believe the feeling of her orgasm on his cock. He bent down and kissed Mia on the lips with a lustful passion. Both stayed together as they came down from their respective orgasms. "That was incredible!" Nathan said nearly voicelessly. "Yeah. Better than with Nina or Becca!" Mia sighed. She turned to Becca, "Your brother is amazing. You're gonna love it when he has sex with you, too." "That'll have to be tomorrow." Nathan said as he rolled off of Mia. "It's getting late and I don't think I can do any more tonight." "That's fine." Becca said. She went over to her brother and kissed him. Nina followed her and kissed Nathan. Finally, Mia kissed him once more. "Thank you for being my first." Mia said. "And thank you for being mine. We'll never forget this, will we?" "I hope not." Nathan watched as three naked girls, one with his cum in her pussy, walked out of his room carrying their pajamas. The next day, they had to behave around their parents. Mia and Nina left with regret, but they knew they would be back to continue this. That night, the parents went to bed early again, leaving Nathan and Becca downstairs by themselves. In no time, they were in Becca's room, their clothes on the floor. "I loved watching you have sex with Mia." Becca said after they had kissed. "And you were so hot playing with Nina." Nathan said. "I wish I knew you girls were so lezzie earlier. How long has this been going on?" "Mia and her sister have been kissing and playing with each other for about a year. I started about six months ago." Becca admitted. "Mia finally got up the nerve to get you involved last night. It was actually my idea. We've been talking about it for about a month." She grinned with that admission. "Well I thank you for that." Nathan smiled back at his sister. "I want you to lick my pussy first." Becca said to her brother. "You saw how Mia did it with both Nina and me." She lied on the bed with her legs spread. Nathan got into position and put his head near her pussy. "You look so sexy, you know that?" Nathan said to his sister, looking up her body. "You think? Even without boobs or anything?" she asked, blushing slightly. "Absolutely. And definitely with no hair down here." he said before licking her pussy. The taste was incredible and the feeling was nothing that he had imagined. "Put your tongue between my lips. Press it inside." Becca said as she reached down and spread her pussy lips open. Nathan obeyed and found he loved the taste of his sister's sex. His tongue pushed into her tight crevice making her moan. "I'll need to get Mia and Nina to teach you." Becca moaned. "But now, let's do it!" Nathan was smiling as he took his mouth from her pussy. He climbed back up her body and put is cock at Becca's pussy. He leaned down to kiss his sister on the lips. She hugged him to her and then told him she was ready. Slowly, he pushed his cock into her pussy. Like Mia, though she was a virgin, her hymen had been broken during her sex play and felt as her brother's cock slid completely up into her cunny. Their hips met and Nathan knew he was all the way in. "How do you feel?" Nathan asked his sister. "Oh, this is incredible!" she replied with a slightly deeper voice. "We're going to do this a lot from now on!" Their eyes met and the newly changed feeling of love shone through that surpassed sibling love. It was the unmistakable feeling of incestuous love. Slowly. Nathan pulled out of his sister before pushing back in. With no other girls around, he found he could concentrate on the love he felt for his sister. They kissed each other tenderly as they had sex. His hands started to rub at her nipples and her hands moved down his back and caressed his ass. They had sex like this for a few minutes, both siblings just enjoying the sensations of sex and the emotional aspect of incest. In and out, Nathan's rhythm with his sister was ecstatic. She met him as her hips rose and fell in counter to his strokes. "Why didn't we think of doing this sooner?" Becca asked her brother. "I have been kind of thinking about it since last year." "I wish you told me." he replied as he slid his cock in and out of her pussy. "I've been playing with myself for all this time." The feelings were so incredible that both siblings were feeling. Her young pussy was so tight around his teen cock. He started to move faster in and out of her tight sex. She could feel the intensity. "Oh yeah Nathan! Faster!" she begged. He was going as fast as he was comfortable with, pulling almost all the way out before pushing back in hard. "Oh Becca! I feel so good!" Her tight cunny was massaging his cock so much. Her muscles were just playing so much with each inch of him. Finally, he couldn't take it any more and buried deep inside, he shot his first incestuous load into Becca's pussy. She wasn't far behind him as she felt her own orgasm hitting. She came almost as soon as her brother's sperm shot into her cunny. Instinctively, she reacher legs around his hips, shoving Nathan deeper in her pussy. After a few minutes, he rolled off his sister and the two just reveled in their new sexual relationship. They kissed a few times as lovers. "I still want to watch you have sex with Nina." "You know, I could talk to Kevin and Mike." Nathan said referring to two of his friends, a twelve and fourteen-year-old set of brothers. Three girls, three boys." "We were wondering what we could do this weekend." Becca joked. "Mom and Dad will be gone most of Saturday." Nathan smiled at his sister. "We can all meet here." "Perfect." Becca said with a kiss for her brother. "Until then, let's sleep together tonight." They knew their parents wouldn't come downstairs to look in on them, so it would be fine to spend the night together. This was the first time they had slept together and it was so comforting for them The next day, both kids went over to their friends' homes to tell them of their plans. At Mia and Nina's house, Becca told them that she had sex with her brother. "It was great, wasn't it?" Mia said as the three girls were sitting on th e floor of Mia's room. "It was incredible!" Becca admitted. "And Nina, this weekend, you'll get to have him." "Yes!" Nina cheered. "But even better is that Nathan is going to try to invite two of his friends over as well." "Who?" Mia asked, intrigued. "Kevin and Mike Nichols." Becca said with a grin. "They are hot!" "I know. Kevin and I almost kissed once at his house, but we heard his mother coming and quickly stopped." "Well, now you can do anything you want with him this weekend. My parents are going to be gone almost all day on Saturday." "What about me?" Nina asked. "I think my brother wants you. That way, he gets to have all three of our virginities." "I wish we had a brother." Nina lamented. "At least you have a boy to have sex with right in your house." "True, but you have each other." Becca said before leaning in to kiss Nina. Mia took Nina's shirt off after they finished the kiss and Becca removed Nna's shorts and underwear. Immediately, Mia went to her sister's pussy and started to lick her sister's pussy lips. Becca moved from Nina to Mia, who was wearing only a sun dress. Becca moved the hem up to reveal her best friend's bare ass and pussy. She pushed her finger into Mia's pussy. Soon, Becca laid down on the floor and brought Mia's hips down to her, slipping her tongue into Mia's hot pussy. They unfortunately couldnt play too much that afternoon as they heard Mia's mother coming to the door to tell them they were going to leave. That night, Becca and Nathan met up in her room and confirmed the weekend was on. "Did you tell them that we have had sex?" Becca asked her brother referring to Kevin and Mike. "I told them I had sex with Mia, not you." Nathan said. "But I did say you were willing to have sex with them." "Why?" Becca asked. "I don't know how they would feel about us having sex since we're brother and sister." "Will they be home alone tomorrow?" she asked. "Yeah, why?" "Cuz we are going to give them a sneak preview of this weekend." Becca told her brother. "Let's not do anything tonight so we'll be ready for tomorrow!" She said before kissing her brother lustily. "Fine, but I'm still sleeping here tonight." Nathan said with a smile. Naked, both siblings acted as a married couple and slipped into bed together for a nice night's sleep. The next day after lunch, they went over to the Nichols' house. They got there just as their parents were leaving. They would be gone until after dinner, so they knew they had the entire afternoon to get the boys into incest. Once inside, they started to talk. "You're serious about us losing our virginity this weekend?" Kevin asked. "Yes. What did Nathan tell you?" Becca asked. "That it would be us and your two friends, Nina and Mia at your house for some sex." Mike said. "Yep." Becca grinned, she then turned to Kevin. "Mia wants to have sex with you, Kevin. You two want to go out I hear?" "Yeah. " Kevin smiled back at Becca, a little embarrassed. "Well Nathan is going to have sex with Nina. That leaves you and me, Mike." "So I get to take your cherry, too?" he laughed a little. "No. Nathan beat you to that two nights ago." she calmly told him. The boys stared at the two of them. "But you are brother and sister!" Mike said shocked. "So? I know he loves me." Becca said. She turned to Nathan and kissed him. The brothers just stared. "Incest isn't as bad as you would think. Mia and Nina have been playing with each other for about a year." "That I have to see." Kevin grinned. "Well you will on Saturday." Becca told them. "You two also have to do some stuff together. In fact, you're going to join them, Nathan." "What? But that's gay." he said, surprised at his sister's ideas. "You loved watching us playing with each other, didn't you?" "Yeah." "Well we are going to like watching you three play together." Becca said. "Now what say we get undressed and you two can watch as Nathan and I have sex?" Becca didn't wait for the boys as she took her clothes off. The three boys were naked in short order, Kevin and Mike seeing their first naked girl. "You like what you see?" "Yeah!" they said together. She went over to Mike and gave him a kiss on the lips. He hugged her close to him as they kissed. She then went over to Kevin and kissed him as well. Both of their cocks were as hard as they could get. "All right, now you two kiss each other." The brothers looked at each other and shrugged, "I'll do anything to get to have sex with a girl." Kevin said to his brother. He leaned in to his brother and they kissed as they had with Becca. "All right Nathan, your turn." Becca said. He thought he meant with her, but she continued, "Kiss Kevin and Mike." He shrugged and went over to the brothers, kissing first Kevin then Mike. He didn't enjoy it as much as he did with Mia and Nina. "Now you two can play with each other while you watch us having sex." She laid down on some cushions placed on the floor, her legs splayed for the boys to see. Nathan climbed into position and slowly slid his prick into her pussy. The brothers were shocked to see actual sex going on in front of them. Their cocks were sticking straight out and lost their modesty as they started to masturbate right in front of each other. "I can't wait until Saturday when you stick that in me!" Becca teased Mike. `What does she feel like, Nathan?" Mike asked. "Incredible!" he replied. "Like a warm wet glove around my cock." Nathan was sliding in and out of his sister as he was watching the two boys playing with themselves. "Mia was just as amazing." he said to Kevin. "Come on boys." Becca said, looking at the two brothers. "You can see we are into incest. I want to see you two playing with each other as well." Kevin and Mike looked at each other and shrugged. "Why not?" Kevin said, "If it means we get to have sex with two girls in a few days." He reached over to his brother and started to play with his cock. "Suck it." Mike said of his younger brother. "Only if you do me, too." Kevin told him. "Deal." Mike laid down and Kevin took his older brother's cock into his mouth. Mike immediately moaned at the first mouth touching his cock. "That looks so hot!" Becca admitted. She turned back to her brother, "I can't wait to see you sucking them as well." "And I can't wait to watch you girls licking each other out. Nathan grinned at his sister before leaning down to kiss her lips. His hips were moving faster up and down, his cock moving faster in and out of his sister. "Yeah Nathan!" Becca called out. Mike sat up enough to watch Nathan pump in and out of his sister. Becca was nearing her orgasm and was letting Nathan know it. She wrapped her legs around Nathan's ass and was hugging him closer to him. As soon as she came, her pussy grasping at his cock, he was also lost in his own orgasm. Kevin had stopped sucking his brother to watch as Becca and Nathan both hit their climaxes. "Oh Becca!" Nathan called out to his sister as his cum gushed into her pussy. Becca suddenly felt a renewed climax as her brother's jism filler her pussy. "Holy crap!" Mike said in awe of what he just watched. "C'mon dude, finish sucking me off." Mike said to his brother. Kevin went back to sucking at his brother's cock. "I loved that so much." Becca said to her brother as he came down to kiss her on her lips as his cock slipped out of her pussy. "Hey Becca," Nathan grinned at his sister. "Why don't you have Mike suck your pussy?" "Good idea." she said as she straddled Mike's chest. She moved up to his face and put her pussy right over his mouth. "Just lick and shove your tongue in her pussy." Nathan directed Mike. He obliged and could immediately taste an interesting incestuous mixture of sisterly juice and brotherly sperm. It was getting intense for Mike as his brother continued to suck his cock while he was now sucking at his first pussy. A minute more and Mike was moaning into Becca's pussy as he was hitting his orgasm. Kevin soon received a mouthful of his brother's cum in his mouth. The first jet was surprising and it leaked from his mouth, but the other spurts Kevin managed to keep. He swallowed it and told the group, Not too bad." Becca got off of Mike and kissed him ."How was I?" Kevin asked his brother. "Amazing!" he replied. "I guess it's my turn now. Get on me like Becca was." Kevin straddled his brother's face and soon got into a position where his cock was at the right position. Becca got him a pillow to raise his head and in no time, Mike was sucking his brother's cock. "Come on Nathan," Becca said, "my pussy needs more licking. Lay down next to Mike." Nathan did so and soon, Becca was straddling his face. She turned toward Kevin and kissed him as their respective brothers were sucking them off. As they kissed, he felt her body down the front, paying special attention to her nipples. "Ooh, you're good. Mia's gonna like this." Becca teased Kevin. Soon, Kevin was feeling his own orgasm hit and shot his cum into his brother's mouth. Becca quickly leaned down to kiss Mike as Kevin took his cock out of his brother's mouth and took in some of Kevin's sperm. A few minutes later after everyone was calmed down from their orgasms, Becca and Nathan started to get dressed. "We'll see you at out house on Saturday. Get there about noon." They left and went straight over to Mia and Nina's house. They went out into their backyard on the swing set. While Nathan and Mia sat on the swings, he and Becca told of their exploits with Kevin and Mike. "Cool, so they are in?" Mia grinned. "Absolutely." Becca said. We told them to get to our house about noon on Saturday." "We'll be there at eleven." Nina said. "Fine, but we're not fooling around until they get there." Becca reminded her friends. "That's OK." Nina said as she went over to Nathan and gave him a kiss. The next few days were hard for Nathan and Becca. They decided to abstain from any more sex until the weekend, but they did play with each other. On Friday night, they even took a shower together. This was their first shower together since they stopped bathing together many years earlier. First Nathan soaped up his hands and cleaned Becca's wet, naked body and then Becca gave Nathan's body a washing. It was so difficult not to make each other orgasm. Ultimately, they went to bed eagerly anticipating the next day.
