The snow was falling and the wind was howling outside. Our log house was well built and warm thanks to a good fireplace and oil heat from an oversize furnace. The bedrooms are located on the second floor and since heat rises, floor registers are open in the winter to allow the heat to permeate into our rooms. Mom and dad have a master suite at one end of the house on the second floor. My two sisters, 11 and 13 share a room. Connected to their room is a shared bath with me. Locks are provided on the bathroom doors so no one is deprived of their privacy, however, they are usually left unlocked. Cally and Sara, my sisters, are two of the prettiest young ladies I know. My name is Nathan and I am almost 15. I love my sisters dearly and since we live in the sticks, actually a forest with a large lake. Mom is a teacher and home schools us since we live so far from town and travel in the winter is limited due to heavy snow from October through March. Dad works as a consultant for a company that makes electronic things. He does all of his work from home with a state of the art desktop computer with three large screens. He is quite an expert with drawings, schematics and such. Mom is also the keeper of finances. She cooks, sews and makes sure that we all learn the ways of wilderness living. I learned to chop wood, cut trees, build tree houses and such. My sisters have learned to cook, sew and such too. We all get along. Dad and mom are very loving parents. They are still as much in love as when they first dated, or at least that's my observation. They cannot seem to keep their hands off each other and like father like son I find it hard to keep my hands off my sisters. We grew up basically clothing optional when its warm. Of course, the house is usually warm in winter so we dress minimally. Mom and dad have a large family bathtub and hot tub in their suite. We kids have a tub/shower suitable for two at a time if we are careful. We have all three been in there at the same time when we were smaller but lately it's usually the girls together and me alone. Of course, Sara and I have taken some liberties since she had started growing boobs. I think she will be like mom in that department. Mom is a 36 DD according to her bra. I think I will probably be like dad since I have a fairly large penis now at age 15. I hang loose at about 3 inches and an inch thick but when hard I'm a full 6 inches and an inch and a half thick. Sara likes touching it and jacking me off when we bathe together. Cally and I have bathed together too but right now she has not shown any other interest in doing sexual things with me. She is still immature but I love her just the same. My bedroom window was rattling from the wind. Even with storm windows there was some leakage of air around them. Dad came into my room to check on it and said it was fine for now but he would have to repair it when the weather cleared. I had just fallen asleep when there was a loud CRASH and breaking glass. I jumped from my bed and flipped on my light. That window blew into my room. Thank goodness my bed is across the room about 10 feet or I would have been covered with glass shards. Dad came running and upon seeing that I was OK then came over and hugged me. Mom came too and we had a group hug. Mom's breasts were soft pillows to my face as she hugged me. My penis got hard instantly and I got a bit embarrassed. Sara and Cally were awakened too by the blown out window. Dad surveyed the damage and declared a new window was needed and some plasterboard needed repair. I couldn't sleep there tonight or for a few nights. "Sara has a double size bed." Mom stated. "Nathan can sleep in her bed until we get his room repaired. Nathan, take your blanket with you so you don't take Sara's." "Mom," Sara said, "are you sure its ok for him to sleep with me. I mean... well you know..." "Sara, it will be ok. I'll have a talk with him privately. I'm sure he will respect your dignity, won't you son?" "Sure mom, Sara it'll be ok. You know I love you and would never do anything to hurt you." "Come Nathan, let's you and I have a talk and your sisters can go back to bed." I went with mom to her room. It was nice and toasty warm. She had me sit on her bed as she began telling me things I should already know. She began by telling me that we kids had been raised to be loving, kind and not be ashamed of our bodies. "I let you take baths together even after you and Sara got older and you had a growth spurt and she began growing breasts. I know you and she touched each other and played doctor/nurse and mommy/daddy games learning about your bodies. I also know that you are virile and shooting semen. It's normal for boys to masturbate and have fantasy girlfriends. Sara is a woman in most respects. You know she has been having periods for several months now. I have taught her that her body is hers and what she does with it is her choice. I know that someday you and she and even Cally will come to your bed and you and she will make love to each other. I am telling you this tonight because I love you and want you to know that should your emotions become so strong that you and she couple it will be during her safe time so you should not have that worry. Now I am not telling you that you and she should couple but that your dad and I love you very much and its normal for hormones to drive you to do things so when you crawl into that bed with your loving sister, you do so with my and your dad's blessing." "Mom, I'll be careful and not hurt her in any way." I said. "Now go to your sister and get warm." Mom said. I stopped off at the bathroom and relieved myself. My penis was warm and semi-erect. I was anxious but scared too. I walked to her room and knocked. "Come In, Nathan." Sara said. I opened the door and stepped into her room. She was sitting up in bed looking at me with wide eyes. I could tell she was scared but heck we had played together as kids and laughed and got along great. We played `I'll show you mine if you show me yours' several times and we laughed about it. Now here I was stepping into her world now and I realized I needed to be there for her. I closed the door and stepped towards the bed. She lifted the covers invitingly to me. I could see she was naked, at least her chest was naked and I could see her cup cake size breasts. My cock responded and began rising. I took off my pajama bottoms and slipped into bed with her. I was chilled from the lack of heat in my room and the cooling wind that had blown through the house. "You're cold." Sara said as I covered up our skin touching. She was warm to me. I lay on my back and kicked my legs to warm them with the friction of the sheets. "I'm sorry," I said. "I am cold and you are so warm. I would hug you but I need to get warm first." "You can hug me. My body heat can warm you even though I may get chilled." She replied. I opened my arms for her to hug me and she and I hugged full length. My cock instantly hardened to fullness and was poking her between her legs. I kissed her and held her close. The kiss was meant to be a normal peck on the lips like we always did, but this time when our lips touched there was a passion never before felt. We held our lips together and pecked each other. Our lips were dry and we both opened our mouths to lick our lips. Our tongues touched, wet and sensuous our eyes flew open at the initial touch. The feeling was instantaneous. An instant warmth filled my body as we kissed again and again. I hugged her tightly. I could feel her breasts pressing into me and her little nipples got all pointy. I then realized that she was as naked as I was. She was lying over me, my hands rubbing her back as she rubbed me with hers. We said nothing for the longest time. We relished our closeness and warmth. As I got warmer I moved my hands over her back, I began moving my hands lower towards her butt. I found her butt cheeks so soft and wonderful to the touch. I squeezed each as we became more passionate in our kissing. By this time she would be making some "mmmmmmng" sounds whenever the feelings she was receiving were especially wonderful for her. Soon, too soon, our kissing ceased and we just lay there holding each other. We were lost in our own thoughts as my hand began tracing an imaginary line outlining her butt cheek and then her waist and her crack. I was lightly following the geography of her body and she was responding with little moves and wiggles. "Does that feel nice?" I asked her as I retraced around her butt and cheeks. "Mmmmmmm, yes Nate... feels wonderful," she replied as she resumed kissing me around my face. The feeling was wonderful to me and at that moment I loved my sister more than I ever had. The passion she was returning to me was so grand. I began to know how mom and dad must feel. I wanted this new bond to never end. "Sara, I love you." Escaped my lips as we caressed and hugged each other. Our body heat soon returned and I was getting overly warm. I kicked off the covers leaving only the sheet partially covering us. Passion overcame me at that moment and I put my hand behind her head and kissed her hard and fervently. My other hand tried to spread her legs so I could fondle her sweet sex. She responded in kind with me kissing me back just as hard. She spread her legs giving me more access to her girly parts. My hand caressed her inner thigh area and found her very wet, not from sweat I learned. It was a warm slicky wetness. My cock was also leaking fluid. I didn't know what it was but I liked it. She scooted up onto me and put her legs outside of mine. My penis was now touching her split and it was very wet. My body began moving up and down and back and forth causing my penis to caress her. We both were moaning as our movements began getting frantic. I wanted to put my penis someplace but never having done this before, really didn't know where it should go. "Nate, let me up. I'll put it in but let me... please. I want you inside me... now!" Sara said lovingly. I released my grip on her since I had been hugging her tightly. She raised up and scooted forward. I saw her little breasts and kissed each as she sat up. I moved my hands to each of them cupping them and squeezing the nipples. She squeaked as I sort of pinched each one. They instantly hardened and I kissed and licked each one. Sara's butt was now sitting just in front of my fully erect penis. She felt very warm as I moved my hands down to assist her in rising up to position my penis at her entrance. I somehow knew just where it was to go and I wanted it there. She raised up and took hold of my penis and positioned it where she wanted it and began squirming herself downward. My cockhead was getting slick with her juices and when she found the exact place she wanted it, she relaxed and dropped impaling herself on my long, thick penis. "AHHHHHHHHH!!!! OHHHHHHH!!!! TAKE IT OUT!!!!" She screamed as her vagina was instantly filled with my hardness. Tears were streaming down her face as she tried to get off of me. I held her tightly as my cock reposed in the tightest, warmest place he had ever been. "Oh.... Sara..." I soothed, "You're so tight. It feels so good. Don't cry honey..." I kept repeating, at the same time trying not to move within her. The noise of her scream awoke the whole house. Mom, dad and Cally burst through the door at the same time. Cally was the first to see us. "OHHHHH!" she exclaimed when she realized what she was seeing. Mom and dad knew instantly that their oldest daughter was no longer a virgin. By this time Sara's body had begun adjusting to the intruder and her muscles began relaxing making room for my thickness and length in her vagina. "Sara," mom said, "relax, the worst is over hon. Nate don't move yet. Let her adjust to you." At about that instant my young body could take no more of the clasping, wetness and heat of her. My balls sucked up and blew their contents through my cock deep into Sara's vagina. She fell over to my chest as that happened and I hugged her close, kissing her fervently and whispering, "ahhhhh" "Ahhhhh" as my cock unloaded its sperm deep within her. Somehow our legs had locked together and that fact was not overlooked by Cally. "Look mom, dad, their legs are locked together." "Yes they are," responded dad. "That's to insure that his seed is delivered deep into her body. I think we may have a new sister or brother for you, Cally." "No Dad," Mom said, "Sara is in her safe time at this moment and maybe she will be so sore that they won't couple during her `O' time next week." Sara and I continued to kiss and couple. She began moving her hips and body nursing my cock deep inside her. It was the most wonderful feeling for me and I think for her too. It was only a few strokes and movements that her clitoris was stimulated beyond its capacity and she orgasmed. "OHHHHHHH..." she moaned as she clasped me with her arms in a bear hug, her pelvis jerking against my now very hard penis. Five strokes and I blew another load of sperm deep inside her. My little sister and parents stood there watching us complete our act of love and initial intercourse. I continued to kiss Sara's tears away, "I love you Sara, more than you'll ever know. I want us to be close like this forever." I told her quietly. My words were not lost on her or my parents. Mom came over and gave us a motherly hug and pushed her daughter so more of my cock would be inside her. Sara moaned as she felt me touching deeper inside her. The next thing I remember was a very warm, wet cloth washing us where we were joined. It felt so good to feel the warm wetness on my balls and butt. I didn't know at that time that Sara had bled allover her sheets and our join was covered in her blood. Mom cleaned us up the best she could at that time. Dad said, "Son, I think you and Sara should come apart and take a bath together. You can use our big tub. I bet Cally would like to be there with you too." Sara raised up from our kissing and looked deep into my eyes. There was a sparkle and love in her eyes I had never noticed before. I leaned up and kissed the end of her nose. "I love you." I said. Mom assisted Sara untangling our legs and separating us. My penis had softened some but still made a plopping, sucking sound as it came out of Sara's vagina. I could now see her gaping, dripping vagina in a whole new light. It was swollen and red from blood and exertion. My cock, too, was red from her fluids and exertion. Sara rolled over to the other side of the bed and lay there breathing hard for a few minutes. I leaned over her and licked a breast and kissed each nipple before I planted a deep, tongue wagging kiss on her lips. She responded in kind. We then got up and hand-in-hand walked slowly, and gingerly to the big bathtub. I looked up and in front of us was Cally all naked, her little butt wagging as she walked. I realized then that she would be in my bed soon and I would have to be gentle with her. Sara and I stepped into the big tub and sat in the extremely warm water. Mom added Epsom salts and a fragrance to the water. "You two stay there quiet until I come back. Keep the hot water running from time to time so you don't get chilled. Cally, you can do the water and sit with them in the tub. Don't do anything I wouldn't do. In other words, do what you feel you want to do. OK?" Mom said. We sat there and let the salts do their magic on our strained bodies. Cally kept asking all sorts of questions of Sara who answered each the best she could. "Yes it hurt at first. Yes I'd do it again. Yes I love him and Yes I love you too. Yes you can touch me and feel just be gentle." Cally reached her hand under Sara and felt her pubes. She also felt me, my cock now soft but filled some with blood. She felt my balls now hanging low in their sack due to the hot water. I kissed Sara and then pulled Cally to me and kissed her. I took liberties with her since she was now vulnerable to my touch. I caressed her flat chest and then her back and her butt. She spread her legs to let me touch her girly parts. Her peach was very soft and tight. I had a hard time getting my finger inside her split. She moaned a few times as I eventually found her love button. Sara was helping too, I learned later. She was holding Cally's hand to her split and showing her what felt good to her by guiding her fingers. About a half hour passed before dad came into the bathroom. He stood at the commode and relieved himself. We all could see his now large cock as he peed. "Daddy, it's so big." Cally remarked. "Do you put that in mommy?" she asked. "YES... he does." Mom replied as she joined us in the room. She was now naked like the rest of us. I could see her full breasts and pubic area. Her stomach had a pooch to it apparently from birthing three kids. She looked wonderful to my eyes. My cock must have thought so too since he filled to full hardness. Sara noticed and said, "I think Nate wants to do it some more." Mom said, "Not tonight. I am taking him with me for the night along with your dad." Mom and dad washed each of us lovingly and then we had a family dry off. Dad took his girls to Sara's room and they slept with him. I don't exactly know what happened in there. That is another story for another day. Mom led me to her bed and we slept after some relaxing foreplay and loving. Suffice it say that she lay on her back and raised her legs wide to let me lie in her wide saddle and bury my teenage penis deep into her motherhood. I didn't last too long this time either. I shot off into her a number of times and then she locked her legs around mine and we kissed like lovers. The next memory I had was waking up as the sun streamed into the window. I was still lying on mom, my penis now fully soft and resting against her pelvis. Soon the door opened and dad and my sisters were standing there, dad wearing only an apron and the girls naked. "Breakfast is ready." He said then walked away. I kissed mom and then we separated and got up. I had to pee badly now. I then joined my family at the breakfast table. Dad said grace as usual but he added, "Keep our family close and loving as we embark on a new direction in our lives. Amen"My Sister and I pt1
