Chris and His Sisters Mf, Mg, gg, fg, inc Chris was halfway through his sophomore year of college when he got the horrific news that his adoptive parents died. He had been adopted as a baby when his mother's bet friend died and was now named the guardians of his three sisters, whom he loved so much. He immediately came home and eventually transferred to a local college so that he could be there for his family. Between their life insurance and their savings, the parents had left Chris with plenty of money to live on. His sisters were now his life for the past five months. Katie was fifteen and very studious. She never was into the party scene and actually seemed to like academics. Beth was eleven and a major tomboy. She liked to wear her dirty-blonde hair short, never past her shoulders, and loved sports, especially soccer. Mary was newly nine and was a girly girl. She loved stuffed animals and dolls as well as swimming, which is something she did in the backyard a lot. They were all celebrating the end of the school year, although they were also a bit sad that this would be their first summer without their parents. They were in their private back yard just swimming and enjoying the first day of summer. Eventually they got out and sat on the pool chairs, Mary with Chris and Beth with Katie. Ever since their parents' deaths, Chris noticed that Mary was much more clingy with him and he allowed it understanding that she needed it. He also noticed that Beth was clingy with her older sister, too. It made Chris feel that both he and Katie were the makeshift parents of their younger siblings and they loved it. A bit later, they all went inside for supper followed by the round of showers. The younger girls showered together leaving Chris and Katie downstairs to talk as they usually did. They felt much closer than typical brothers and sisters due to their special circumstances. After about thirty minutes, Beth and Mary came downstairs. Beth was wearing her pajamas while Mary had on a zipped up bathrobe. "I guess I am next." Katie said as she got up and went to take her shower. "Who's up for some ice cream?" Chris asked his sisters. Both excitedly jumped up and went into the kitchen. They made sundaes and brought them back to the den where Beth and Mary laid down on their bellies on the floor watching TV with their ice cream in front of them. Chris was sitting behind them on the couch. Every few minutes, Mary had an itch on her butt or thighs and scratched over her robe, causing it to rude up. Chris was getting an eyeful as she had no underwear on and could see her part of her hairless pussy and part of her bare butt. As much as he was enjoying the show, he felt the need to say something to his little sister. "Mary, I can see your bare butt." Mary turned around to look at her brother and just let out a giggle as she got up on her knees and pulled her robe up higher, wiggling her butt at him. He was considering saying something to her when Katie came back downstairs wearing her own bathrobe. "Well, I guess it's my turn for the shower." he said and got up to go to the bathroom. The next morning, Chris got up early and went downstairs to see Katie sitting on the couch still wearing her nightgown. "Morning." he said groggily. "Morning." she replied. "I was thinking about taking the girls somewhere special today. I don't want to just stay home today." "Well, we have been talking about the water park for a while." Chris mentioned. Katie loved the idea and agreed. "How about we leave here at about 10am right after breakfast. We can stay there until about 5:30 or 6:00." Katie went into the kitchen to make some breakfast and decide what to do for lunch. At that time, Mary came downstairs to see Chris sitting on a chair in the den. She wore a nightgown without any underwear, as usual and went over to Chris, sitting on his lap. He was wearing some boxers and a t-shirt and still had a little of his morning wood sticking up. Her bare butt on his lap was not helping things. "Morning sleepy-head." he greeted her with a kiss on her forehead. "Guess where we are going today?" "Where?" her eyes looking up with a tired but hopeful look. "To the water park!" he told her. That woke Mary up. "Why don't you go up to tell Beth and then get ready." She hopped off his lap excitedly and ran back upstairs. Mary was upstairs for a few minutes before she came tearing back down to her brother. Naked, she was holding up a bikini and a one-piece. "Can I wear this to the park?" she asked dangling the bikini. "This one," she said now focusing on her one-piece, "is still a little wet from yesterday." Chris was surprised to see his little sister so immodest and was enjoying the show. "You can wear the bikini." he said, trying not to let his voice show any hint of his feelings. "Yes!" she cheered as she dashed back upstairs with her older brother watching her naked ass disappear as she left. He tried to tame his hardness as he went upstairs to find his bathing suit and a shirt. He came back down to his youngest sister sitting at the table in her blue bikini that covered her non-existent breasts. Beth came down soon after wearing a green floral one-piece suit with an open towel robe over it. After breakfast, Katie got dressed in her own bikini that accentuated her slim body and lifted up her smaller than normal breasts They packed a lunch and set off to the water park. The line was long, but they all were eager to wait and get in. Finding a chair to put their towels, Chris warned his younger sisters, "Now stay together or with one of us. We don't want you getting lost." Taking out the sun screen, he added, "And put some of this on. We don't want anyone to burn." He squirted some onto his sister's hands and they rubbed into their skin. "Chris, can you get my back?" Mary asked turning around. Acting as brotherly as he could, he rubbed the sun screen onto her bare back, even under the strap that held her bikini top on. Both girls rushed off to the wave pool as Chris and Katie stayed at the chairs. "I know I say this a lot, but I appreciate just how much you have taken care of the girls with me." Chris said to Katie. "Hey, I can't let you get all of the credit for raising them." Katie joked, "I want to be like a mother to them just as you are like a father." "Does that mean we're married?" Chris joked. "Nah, just unmarried parents, very young unmarried parents." she laughed back at him. Their eyes met in the light-hearted moment and they realized that they did indeed have a closer relationship taking care of their sisters, much closer than normal brothers and sisters. The moment lasted a few seconds before Katie ended the introspective silence, "Can you also rub some lotion on my back?" she handed him the bottle of sun screen and laid down on her stomach. Chris accepted the offer and massaged the lotion into his partner/sister's back. "Thanks." she said as he finished. Chris leaned down and kissed his sister on her cheek. "Thank you, too." he smiled at her before going to find his younger sisters. He was having some strange feelings for his sister. In that moment, his love for Katie had changed, but not in any way he recognized. The siblings had a lot of fun that day, more than they had since their parents had died, They stayed until nearly 6:30 when they decided to leave and get some supper before going home. "All right, shower time!" Chris announced as they got in the door. "And after that, we can have movie night." The two girls went straight upstairs while Chris and Katie sat down on the couch, careful not to get anything wet. "I noticed how you laughed when Mary came downstairs naked this morning." Chris said to his sister, "Are you sure you want to encourage her?" Katie again gave a small laugh. "Oh, Mom and Dad lost that battle with her. In fact, they had decided to allow for a less modest house in your freshman year." "Really!" Chris was amazed at his parents. "So you think we should just let her be as naked as she wants?" "Hey, I may join her now and then." Katie admitted. "Beth may also want to be immodest. Our big brother won't mind that, will he?" she joked rubbing her hand on his cheek. "Three cute girls who want to be naked? Should I complain?" Chris nervously laughed. "What would you say if I suddenly decided to take up the nudie life?" "Maybe I'd enjoy seeing my big brother naked." Katie responded. Chris smiled, hiding his intense nervousness and feelings that he'd kept inside of him all of the years. When he was 13, he started to really see how cute his eight-year-old sister was. Before that, he would see her naked quite a bit, but then, suddenly she got more modest and he found himself missing her naked body. "So why aren't you naked?" Chris decided to up the ante. "I sure wouldn't mind seeing you either." "Maybe we can start later on." Katie suggested. "I don't have to put on my pajamas after my shower." Their eyes met like they had at the park, this time in a more intimate surrounding. He was falling in love with his sister. She was falling in love with him as well, or rather, she was now not hiding her love for him. His arm went around where she was sitting and touched her bare shoulder. They leaned in to each other slowly and felt as their lips pressed together. Neither of them had ever had a boyfriend or girlfriend so this was the first real kiss for each of them. The kiss wasn't perfect, but it is not the kiss but the love behind it that matters anyway. The ended the kiss after a minute and they smiled at each other. "Wow" Chris sighed. "I loved that so much." Katie whispered to her brother. "Even though you are my brother, that still felt right." "I know what you mean." Chris agreed. "I love you so much." "I love you, too." Katie said before she leaned in for another kiss. This one was interrupted when they heard their sisters come bounding down the stairs wet-haired and wearing their pajamas. "My turn for the shower." Katie announced as she got up from her brother with a big grin. About halfway through the TV show the girls were watching, Chris decided to talk with them about their modesty, or lack thereof. "So Katie tells me that you three were not so modest starting last year." "Mom and Dad let me be naked all the time." Mary admitted. "It was so much fun." "How about you, Beth? Did you enjoy it, too?" Chris asked the middle girl of his sisters. "Yeah." she said in a non-committal tone. "I liked not having to get dressed. They even talked about going to a nudist park." She was still slightly uncomfortable talking about her parents. "Well, Katie and I talked it over. If you want to go naked, you are free to do so." Chris announced, still a bit nervous about how he was going to handle potentially having three naked girls around. Mary squealed in excitement and shed her pajamas instantly. She jumped up onto the couch and kissed her big brother on the cheek with an embrace around his neck. Chris found his arms and hands touching the bare skin on her back dangerously close to her cute, shapely ass. Beth looked at her sister with annoyance. She was slower and only stripped down to her panties. He dared not take his shorts off as now his cock was starting to grow. He knew he shouldn't be attracted to his sisters, but their nudity combined with what happened between him and Katie was also adding to his feelings. Watching TV was not as easy with his sisters sitting and lying on the floor in front of him, all the bare skin showing. His eyes were constantly going to Mary's bare ass cheeks and Beth's panty-covered ass. Katie came down about a half-an-hour later after the show ended in just a robe. "My turn to shower." Chris announced. He went upstairs and got under the hot water of the shower. He could not believe how much everything had changed in this one day. He knew his relationship with his Katie had changed. And now he was going to have three sisters who were going to be very immodest around him. He knew what kind of effect it would have on him and he wasn't sure how Beth or Mary would take it. When he was done, he wrapped his towel around his hips and went to his room. On his bed waiting for him was Katie, her robe opened slightly so he could see her small but luscious breasts. "Hey sexy." she said as he entered and closed the door. "What are you doing here?" Chris asked, adding, "Not that I'm complaining." "The girls are involved in a movie downstairs and I felt we could talk some up here." she smiled. "So why is your robe opened?" he asked with a smile on his face as he sat on his bed still just covered in his towel. "I want to continue with the kiss." she said as she sat up, her robe falling open and exposing her chest. He said nothing as she leaned into her half-naked brother and kissed on lips with a little more passion than the two experienced before. "You know, this is incest and is wrong." Chris warned her, and himself as they parted lips. "I'm also too young for you." she said in her most seductive voice. "But I won't tell if you won't." Kneeling on his bed, she let the robe fall off of her body, exposing her naked body to Chris for the first time in so many years. She went to her brother and pulled a little on the towel, making it fall off of his hips. His cock sprang to life as Katie admired her brother's incest pole. "I want that in me." Katie whispered to her brother as she fell back on his bed. He laid down next to her as they embraced in their sibling foreplay. Their kissing was lust-filled this time, all hesitations gone. He rolled over and was on top of Katie, his hands on Katie's small, fifteen-year-old breasts caressing them. "I want you so much." Chris told his sister. "Then take me." Katie replied. "Make my dreams come true!" "Wait. What if I get you pregnant?" Chris said, involuntarily stopping. "I just had my period last week. I'm fine." Katie replied, kissing him once more. "Get ready." Chris said. He positioned himself with his cock touching his sister's virgin lips. Staring into each other's eyes, Chris pushed and the head of his cock was buried inside of his sister. "This may hurt some." he warned his sister with some concern. "I lost my hymen a few years ago from masturbation." Katie told him, rubbing her hands on his chest. "But thank you for caring about me." She kissed him once more. Knowing that he had nothing to worry about, Chris pushed deeper and deeper into his sister. Her tight cunt was warm and inviting to his cock. Masturbation had never been so amazing as this. A warm, tight, silky wrap enveloped his cock. He finally stopped when he realized he was completely buried in his sister. "Oh gawd! I'm in. I'm all the way in you!" Chris shouted in surprise. "We waited too long for this, Chris!" Katie squealed out. "I think I've wanted you since I was nine." she said, regaining some composure. Chris looked at his sister with more amazement. "If only I knew!" he said before pulling out of his sister slightly. He pressed back in with a moan from both of them. With each stroke, he was taking his cock out a little more. Half of his cock was still in her and the downstroke felt incredible. Chris looked at his sister's face an could see the expression of primal lust. He was sure he had that same expression as it was how he was feeling. In a minute, Chris was taking full strokes, his cockhead the only part staying in before pushing all the way back into his sister. Now he started to increase his pace, Katie countering each stroke of his with her own upward and downward motions. She took her arms and puled Chris down into their first post-virgin kiss. "Oh, oh. Yeah! Katie, I'm going to cum!" Chris called out as he felt his orgasm building. Nothing had ever felt this good and it was even better knowing he was about to shoot his jets into his sister. He shoved down hard as he let loose his cum, squirting load after load into her incestuous womb. "Chris!" Katie shouted. She felt her brother unloading his virgin cum into her cunt, touching off her own orgasm. After she came down from her most intense orgasm, she kissed he brother hard on the lips. That was when Chris heard some giggling behind him. He quickly got off of his sister and turned around to see his two younger sisters, naked with the best grins on their faces. "That was so cool!" Beth exclaimed. Chris stared at them in shock. It was enough that he just had sex with his one sister, but that their younger sisters watching was quite another. "Oh, don't worry about them, Chris." Katie said. "They want you to have sex with them as well." Chris could not talk so Mary started the explanation. "Last year, Mom and Dad introduced us to sex, at least oral sex, licking each other and even sucking Dad's cock. They were trying to think of a way to get you involved." "I was so much hoping that you would be open to it." Beth said as she walked over to the bed and sat down right next to the sexually spent Chris. "Will you have sex with me also?" she asked as she brought his hand to her chest. "Me too." Mary implored as she crawled between her no longer virgin sister and brother. "You can't really say no, now can you?" Katie giggled. "We've been planning how to get you to have sex for a while now." Chris was still speechless so Katie turned to her sister, "Hey Beth, why don't you give our brother more encouragement." she motioned to his cock. Beth eagerly agreed and went between his legs, licking his still wet cock while keeping her eyes on his. "Beth!" Chris called out in shock but didn't try to stop her. He just watched as his young sister sucked on his cock that just moments ago had been inside of her older sister. He turned around to look at his other two sisters when Mary leaned in and kissed him on the lips with some skill. "Please, Chris." Mary pouted after the particularly passionate kiss. "We all want to have sex with you. We love you so much and don't mind sharing you." Chris looked from his youngest sister, whom he just shared a passionate kiss, to his middle sister who was sucking on his cock, to his oldest sister who with whom he had both just lost his virginity and taken her virginity. "Oh I can't say no, can I?" Chris managed to say, now smiling at his three sisters, now looking hotter than they had. "Come here, Beth." he motioned for his middle sister to stop sucking his spent cock and lifted her up onto his chest. He kissed her now, able to taste both his sperm and Katie's formerly virginal juices from her tongue. "So my little sisters want to have sex with their big brother, huh?" Chris grinned at his two girls. "Yeah." Mary eagerly replied. "We've been talking about it for about a year." "Well, since I just had sex with Katie, I won't be able to do anything until tomorrow." Chris explained. "Tomorrow night, Beth can spend the night with me. The next night, it will be Mary's turn. Tonight, Katie and I will be sleeping together." "We'll come up with a schedule." Katie said to her sisters. "We can't all have him at once and we must share." "In the meantime, I want you two to leave us." Chris said. "We have a lot to discuss. Your bedtime is 9:30 which is in about another hour." The girls reluctantly left their older siblings/lovers and went downstairs to watch some TV. He leaned over and kissed Katie with a new lover's passion which she reciprocated. "I can't believe you three." Chris sighed. "We are just so happy that you are interested." Katie smiled. "But I am not sure about Beth or Mary. It'll hurt when I have sex with them." Chris said with concern for his little sisters. "They already know that and are prepared. They've been prepared for a while now." Katie ran her hand through her brother's hair. "What about getting any of you pregnant? If we don't be careful, one or all of you will get pregnant." Chris said with worry. "Well I'd love to have your baby." Katie smiled proudly at her big brother. "We're not biological siblings so that's not a problem. The girls are too young yet, but we will just have to watch when they are at that time of the month." Katie replied. They talked for about a half an hour more before getting up and going downstairs. On the floor of the den were their two little sisters engaged in a double lesbian oral session. Beth was lying on the floor while her sister was on top of her, each licking the other's hairless twat. Beth noticed them enter, but just continued to lick her sister out, hugging her ass cheeks harder, pulling her harder to her mouth. Even after just having sex with the oldest of his sisters, seeing the younger two engaging in a lesbian coupling still surprising to him. "I guess I should expect to see more of this from now on." Chris sighed not taking his eyes away from his two luscious sisters. "Definitely." Katie said as they sat on the couch with front row seats to this preteen show. "We have been doing this with each other for about a year and now we don't have to hide it from you." "Damn it!" Chris said with a smile, "Why couldn't Mom and Dad let me in on the secret earlier? I've missed so much." They watched as first Beth, then Mary orgasmed on the floor. After they calmed from their orgasms, they hopped up, Mary on Chris' lap and Beth on Katie's. Each pair of siblings kissed. For Chris, this was a new feeling. He was surprised by his nine-year-old sister's proficiency with tongue kissing, but she did have a lot of practice, more than he himself, he realized. He could taste an interesting flavor on her lips and tongue, suddenly realizing it was Beth. His hands were caressing her ass cheeks as he was holding his little sister to him. "Not tonight, Mary sweetie." he smiled realizing things were getting too sexualized. He looked over at his other two sisters who were just ending their lesbian kiss. The four incestuous siblings just stayed in that position as they watched TV until the girls had to go to bed. An hour later, Chris and Katie also went to bed, opting now to sleep in Katie's room as an incestuous couple where they cuddled up to each other for the night. The next day, Chris and Katie awoke to their sisters bounding into the room. Beth was extra excited as this was her day to become a woman. She would lose her virginity later on that very day. Wanting to keep a normal family life, Chris quickly ended the sexuality of the moment and just got up, getting ready for the day. The girls went out to their friends' houses while Chris and Katie went grocery shopping, just doing things like any normal family. After lunch, Chris and Katie suggested going to a movie. They eagerly went out to the theater followed by a dinner out at a fast food restaurant. Without realizing it, Katie and Chris were starting to act more like a married couple and parents than two older siblings who were in charge of their younger sisters. At the theater, Chris and Katie sat right next to each other with Beth and Mary on either side of their favorite older sibling, the hand rests lifted so that they could get closer to their older siblings during scary scenes. They got home after 7:00 and immediately the two girls stripped off their clothes, putting them upstairs in their hamper after a stern word from Katie. Chris and Katie kissed as they went into the den and sat back down. "I still can't believe we are going to plan for children." Chris smiled. When the other two girls came back in the room, Chris looked more seriously at Katie. "Katie, I love you. I guess I have really always loved you." Katie looked at him with a wide smile, Chris continued, "I know that we will always be a family, but, " at this he reached into his pocket and pulled out a jewelry box. He got on his knee and presented it to Katie. "I would like you to be my wife. I know we can't be legally married, but I am pledging my loyalty to you." Katie looked stunned, tears coming out of her eyes. Mary and Beth were also shocked and excited, all of them looking at the ring together. "Oh." Katie replied breathlessly, "Oh yes, I accept. I want to be your wife." He took the ring out of the box and slid it on Katie's finger. They kissed afterward, now as engaged siblings. Chris looked at his two younger sisters. "I also want to pledge my loyalty to you two as well, but I could only afford one ring this time. I promise never to stray out of the family unless all three of you accept it." He hugged and kissed both his younger sisters in turn. "You know, when I am 18, we could have a quick ceremony." Katie proposed. "We could go to a justice of the peace and get married, complete with a marriage certificate. "By then, I will have graduated college and if it was fine with everyone, we could move somewhere else and start a family." Chris offered, adding, "And I want to have children with all three of you." "Oh that would be so amazing!" Mary squealed with excitement. "But what if one of us wants to get married to someone else?" Beth, the pragmatist, wondered. "We will never force you to stay with us. It's your life." Chris answered. "I am your big brother and want you to have the best life. Are you having doubts?" "Oh no." Beth said going over to her brother, stroking his cheek. "I just want to have all my options open. Tonight, however, I want to lose my virginity to my big brother." She leaned in and kissed him very passionately. They had some dessert and watched some TV until it was time to go to bed. After getting ready for bed, Beth came to Chris' room. He was just starting to take his clothes off when he saw his little sister. She went over to him and kissed him on the lips. "You all ready?" Chris asked as he stripped naked in front of his eleven-year-old sister. He led her to the bed where they continued to kiss each other in an incestuous manner. "Oh Beth!" he moaned as he kissed down the side of her neck. She moved her head to give him room, purring her satisfaction. He progressed down to her barely there breasts, more like fleshy bumps topped with nice sized nipples. "Do you like them this small?" she asked her brother. "Oh Beth! It doesn't matter what size your breasts will be. I will love them no matter what!" Chris answered as he kissed one and suckled on her fleshy nipples in turn. She was cooing with the attention her big brother was giving her body. To her disappointment, Chris abandoned her now hardened nipples and moved down her young body. He was erotically kissing every part of his young sister's stomach on his way to her prize, her hairless pussy. "Do it, Chris!" Beth begged her brother as she spread her legs, "I have been waiting for so long for you to kiss me down there." Chris looked at his sister and smiled. He then leaned down and pressed his lips on her hairless lips, kissing her treasure box. "Ooh!" Beth sighed. He licked each lip in turn, from bottom to top. She was squirming and he was having a hard time keeping her still. "I got a better idea." Chris said as he guided his sister up and took her place on his bed and slid down until half of his body was on the bed, his legs hanging off the end. "Kneel over my face." he told her. She knew exactly what to do and squatted down so her pussy was at his mouth. He tickled his tongue on her lips once more before opening her lips and pressing his tongue up into her virgin cunny. "Yeah Chris! Oh your tongue is so good!" Beth called out. "I love you so much!" she was being very vocal, much different than her usual shy demeanor. Chris moved his hands from her hips to her fleshy nipples and back down. He couldn't believe this was his sister. This girls was too sexed. "Oh I'm gonna..." Beth screamed before she came in a loud moaning scream. Her preteen juices spilled all over Chris' mouth and tongue. She was so sweet and delicious and slurped up every drop he could find. "Oh Chris, come on. I want to have sex!" Beth demanded as she slid down her big brother's body. She hovered over his cock, sticking straight up. Chris grabbed his little sister's naked hips as she lowered herself onto his prick. Her cunny was extremely wet from her orgasmic fluids and his saliva and she easily slid down, taking the head of his penis into her virgin, hairless pussy. "You're in me!" Beth sighed, letting out her breath. "Oh you feel so tight!" Chris groaned. "I love this! I don't want to hurt you so go slowly." he said to this amazing girl. She slid slowly down his shaft, her pussy splitting to accommodate the welcome intruder. Having no cherry made the sex easier as his cock was being enveloped in his sister's tight, wet, velvety muscles. In what seemed like hours, but was actually less than a minute, Chris felt as his little sister had completely taken his whole cock into her virginity. He looked down and found the sight of his sister sitting on his unseen cock so erotic. "I did it!" Beth exclaimed in a more sultry voice. "You're all the way in me! I am no longer a virgin!" He brought her face to his as they kissed with a recklessness. "Just pull up and press back down when you are ready." Chris told his sister. She looked down at her brother and pulled up slightly. She then sank back down, letting out a contented sigh. "That was good!" she said with a nervous giggle. "It only gets better." Chris told her. Beth repeated her actions of rising a little and falling back down. Every few strokes, she would rise higher than the previous attempt and get rewarded for her diligence. Chris, meantime, was holding her hips with one hand while exploring her body with the other. He first put his hand on her ass, feeling the softness of her skin. He gave her ass a slight squeeze which elicited a grin from Beth. He moved his hand up her body, first up her back to the nape of her neck. Back down he slid, caressing her side as he rounded to her belly. Playfully, he tickled her belly-button before he slid higher, touching her nipples, both in turn. "Ooh yes!" Beth cooed, her back straightening from the manipulation of his fingers manipulating her nipples. Her pace was increasing as she was finding a comfortable rhythm up and down on her big brother's cock. Chris was finding he could occasionally move in concert with her gliding and was pushing up even farther into her pussy. Chris brought his hand back down to her hips and started to play with her clitty that was sticking out from their sexual junction. Within a few minutes, Beth was rising all the way so that only her brother's cockhead was inside of her pussy before falling back down, swallowing everything back up. "Oh Beth, that feels so amazing!" Chris sighed as he felt his cock slip in and out of his sister's vice-like grip. "Can you go faster?" Chris asked Beth as she was riding him slowly. "I'll try." she moaned. Beth found that everything was better when she sped up her strokes on her brother's cock. Each stroke was faster than the previous and soon Beth was bouncing on her brother with abandon. She was grunting with each downstroke "Yeah Beth!" Chris called out as he felt his orgasm begin to build. He held her still, deep on his cock as he shot his incest seed into his eleven-year-old sister. Beth could only call out in a primal lust-filled cry as her orgasm started. Beth's back was arched, her eyes closed as her first real orgasm electrified her body, her very existence. That it was her big brother made it all the better. Her pussy was grasping at Chris's still hard cock, now leaking the remaining sperm into Beth's orgasmic cunny. His sister's muscles were almost painful as they clenched his cock like a vise, a warm, wet, velvety vise. She fell forward, relaxing on Chris's chest. His cock was still wedged inside of her no longer virgin pussy. She leaned in and kissed her brother/lover with post-orgasmic incestuous passion, "Thank you so much!" she whispered to Chris. "That was amazing!" "Not just for you." Chris replied. "You were also great and I am privileged to be the person you chose." Beth rolled off of her big brother. "I'm tired. Let's go to sleep." Chris turned the light off on his bedside table and snuggled up to his eleven-year-old sister, his cum still leaking from her cunny. The next morning, Beth woke him up with a kiss on the lips. They went to the bathroom together and decided to take a shower. Brother and sister washed each other, molesting each other's bodies while sharing a few kisses under the hot water. "Hey sleepyheads!" Katie said after they got downstairs. Both she and Mary were on the couch watching TV. "Hey honey." he said as he leaned over to kiss Katie. "How was it, Beth?" Mary wanted to know. "It was amazing!" Beth recounted her experience from the previous night. "Chris gave me the best orgasm I have ever had." "I can't wait for tonight, then." Mary grinned at her big brother. "So what's planned for today?" "Nothing." Chris said. After breakfast, the younger girls went out and played with their friends. Chris and Katie enjoyed their alone time, now acting as a married couple. They even went shopping for groceries together. Everything seemed new to them with their new relationship, especially after Chris had proposed to her. Outside of the house, they had to keep their feelings in check, however, lest someone who knew them see anything unusual. That night for supper, they decided to have a little barbecue and eat poolside. Knowing the pool could not be seen from neighbors' houses, they chose not to wear anything. The girls went skinny-dipping as their supper was being cooked by Chris. Finally ready, they sat down at the table near the pool and ate their supper. "I'm so lucky to have you three as sisters." Chris proudly proclaimed. "You're just saying that because of the sex." Mary joked. "We are a horny family." Katie acknowledged. "We are just as grateful to have you as our brother." Beth seriously responded. "You are not only a great big brother, but so loving to step in to keep us together." "That wasn't even an option." Chris told Beth. "After Mom and Dad died, you were my responsibility. I never gave it a second thought. You were my life before Mom and Dad died and you will always be my life." "And now we will be an even more important part of your life." Katie added. "Not just as your sisters, but as your lovers." Each girl in turn got up, starting with Katie, and gave him a kiss on his lips, which he reciprocated. They finished eating and played in the pool for a few hours before it started to get late. It was finally time for Mary to get ready for bed. She asked if Chris could take a shower with her and he readily agreed. Chris washed his little sister while she washed him in return. He loved the feeling of her small nipples and her soft hairless lips that soon were going to be spread open with his cock. They got out and dried each other off, retiring to his bedroom. Chris had actually gotten some KY for this experience. He knew that he would need some extra lubrication for his sister's small hole. Before that, however, he wanted to lick his virgin preteen sister out. He started with her lips as the two shared a nice kiss, tongues dancing from mouth to mouth. He couldn't believe how good she was for a nine-year-old. "Beth and Katie are great teachers." she said to his comment. He kissed down her neck and licked at her flat nipples. Just two brown spots on her amazing chest, they hadn't even started to grow. "I love every part of you, Mary." he sighed. "Yes, Katie said some guys like little girls. Will you like me when I get bigger?" "Oh Mary! You are my little sister. I will love you no matter what. When you get bigger, that just means that you are ready to give me a son or daughter." As he was kissing her nipples, his hands were working their way down to her hairless slit. He tickled and caressed her bare lips. "I love this." Mary cooed as she just allowed her big brother complete access to her naked body. He finished with her nipples and kissed down her stomach. Removing his finger, he replaced it with his own lips. He kissed her pussy lips with vigor. He wet her hairless flesh with his tongue, tasting his baby sister's skin. He couldn't help notice how soft the lips felt. Finally, he pressed his tongue between the lips, into the tiny hole. Mary took in a deep breath as she felt her brother's tongue enter her virgin sex. She was so tight! Much tighter than her sisters, Chris thought. Of course, she was also the youngest and smallest of her sisters, so that made sense. He took his tongue out and started to suckle on her little clitty that was now visible at her opening. "Oh yeah!" Mary moaned, "I love it when Beth licks me there." That made him even more horny as she was talking about her sister licking her pussy and he attacked his little sister's hairless twat with gusto. He was sucking at her clitty as he was plunging his tongue into the tight envelope that was her virginity. His right hand was traveling back up her body and molesting her nipples. "Do me more Chris!" she moaned some more. "Oh I can't wait until your cock is in me!" She was moving more on the bed, her hips sliding one way and the other. Chris could tell that her breathing was increasing as she was nearing her orgasm. He brought both hands under her ass and lifting her up slightly to his mouth. She was calling out in her first brotherly orgasm and Chris drank up all of Mary's young, sweet nectar. After she came down from her high, Chris went up to her and kissed her passionately on the lips. He rolled her over during the kiss so that she was lying on top of him, their chests seductively touching. "Whenever you are ready, Mary." he said after their lips parted. "Just straddle my hips and lower yourself on my cock." Mary slid her body down her big brother's naked body until his cock was sticking up in front of her. "Hot damn, you are big!" she said with a nervous excitement. She knelt up and placed the head of her brother's cock at her small slit. "Here I go." Mary announced as she slowly tried to slide down. Nothing happened at first and it was almost painful for Chris as she was putting more and more pressure on the tip of his cock. Finally though, the head of his cock slid into her virgin tightness. She stopped as soon as the head of her brother's cock was inside of her virgin slit. "You're in me!" she said in a suddenly deeper voice. "How does it feel?" Chris asked his little sister, holding her hips firmly to keep her steady. "Amazing!" she sighed. Mary stayed for a minute before allowing herself to slip down a little farther down his brotherly pole. Tears were coming as each inch of his cock was opening her tight crevices. "Are you OK?" Chris asked with concern, noticing her tears. She smiled and looked at him with a new preteen lust. "Better than I have ever felt." she answered as over half of his cock was now inside of her. She stopped when she could not fit any more in her and let him know. "That's fine, Mary. You are still so small and I am just too big." he said, feeling every muscle of her cunny on his cock, the pressure was so intense. "Lift up when you are ready and the slide back down, but don't pull all the way out." Chris instructed his no-longer virgin nine-year-old sister. She followed his instructions and rose up so about an inch of his cock slipped out. Slowly, she allowed the cock to sink back into her pussy. "Ohhh!" she moaned. She repeated the step again and again until she was taking most of his cock out of her before swallowing him back on her downstroke. "Damn, you are so tight!" Chris moaned. "Oh I love this so much!" He reached up and rubbed at her nipples. "I love you!" Mary sighed on her downstroke. She tried to go faster, pulling off of his cock and dropping back down with increased speed. The pace was making her so hot and feeling so great. All of the pain was gone, replaced with a sexual delight. The increase in speed and the impossibly tight vice-like grip that Mary's cunny was giving him was bringing Chris to climax. "Oh Mary!" Chris called out. "I am cumming. Oh yeah, I am cumming!" he held onto his sister's hips as he shot his incest seed into his youngest sister. "Aaahh!" Mary screamed as her orgasm was being enhanced by her brother's cum. She felt the warm jets paint her cunny walls with his brotherly cum, her nerves reacting to each hot squirt. It felt so amazing that tears were forming in her eyes. She stayed in position until her orgasm ebbed. She fell onto Chris' chest as brother and sister enjoyed a post-orgasmic kiss that linked the two together. "I know why Mom and Dad wanted me to experience this now." Mary said. "It is incredible!" "It didn't hurt too much?" Chris asked. "No. It did hurt a little, but then the good feelings came." Mary assured her big brother. "Well, you may hurt tomorrow." Chris told her. "But we'll worry about that when it comes." Mary rolled off her brother and lay down on the bed next to him. They snuggled until first Mary, then Chris fell asleep.
