In part one, Sara and I lost our virginities to each other during a winter storm when my bedroom window was blown out. In part two, mom took me to her bed to impregnate her since dad could no longer perform that task. Sara and Cally continued to be great sisters. Cally was introduced to oral sex by me and Sara. Sara has told me she wants babies from me and upon mom hearing that commented that dad is going to be adding to this house come spring. Mom felt a flush come over her and she said the last time she felt that she conceived Cally. I let me lie in bed and bask in the glow of our lovemaking while I took my sisters and let them bathe me. We then left mom to nap and let my virile sperm wend their way deep into her body to either be absorbed or reinforce that which may have happened already. In Part three, Cally became interested in me. She took great care to wash me after my coupling with mom. Sara was very loving too. She helps prepare Cally for her first sexual encounter and later defloration. Life in our house takes a definite turn as now all of the females are having periods and being my sisters are still young "careful" becomes the byword. Of course, dad doesn't have to worry since his accident rendered him sterile. The story continues. Part Four Cally slept fitfully that first night after her defloration. Mom gave her some medication to help with her cramps. Sara and I slept together but it was strictly sleep since my penis was worn out from all the recent activity. I slept soundly and had pleasant dreams. The next morning mom was up early and cooked a wonderful breakfast of deer sausage, eggs and hash brown potatoes. Dad still wanted to hunt some since there was a lot of snow on the ground. The weather had cleared and looked beautiful though cold. "Kids, Breakfast is ready," yelled mom as we began waking up. The smell of breakfast was wonderful. I ran to the bathroom to relieve myself only to find Cally already on the pot and Sara standing in line. I stepped into the tub and ran the water to warm it in preparation of my quick shower. Of course, I relieved myself there while showering. The girls joined me and we quickly soaped and rinsed each other. Sara helped Cally with her pad while I watched this new event in my life. Breakfast was full of conversation, mostly about our studies. Being I am older my studies are more advanced from Cally's and Sara's studies. However, they are definitely ahead of where most kids are their age due to my advanced studies. I am due to take a standardized test for the 10th grade and while I have accomplished work in the eleventh grade I am still apprehensive that I won't do well on it. I have a burning desire to graduate high school and then attend university so I can be independent and useful to society. I am excellent in math, science and English but not in the arts. After breakfast mom and the girls cleaned up the kitchen while dad and I went to his study and he helped me with my problem course. After he was satisfied I was comfortable and understood the situation he proceeded to get ready for his hunt. About 30 minutes later, he came and hugged and kissed us goodbye as he left with his rifle and fishing rod. I never understood the significance of carrying a fishing rod when going hunting. But then what do I know. I know he carries a GPS, backpack with camp tent and dried food along with other survival supplies. He also has a very large buck knife. He is very safety conscious so we don't worry about him. He also carries a two-way radio that can be used in emergency. We all began our studies in the workroom. Mom lectured us on a subject for about 30 minutes then left us to study. Sometime during our study, Cally finished her work before Sara and I and began playing erotica with me. She rubbed my leg and would make little mewing sounds trying to get my attention. I could tell she was feeling much better with her period but today mom was going to be teaching us all about birth control techniques and health issues. I was looking forward to this study since I sure didn't want to become a daddy with my sisters, at least not yet. Now mom is carrying my seed in her body and I hope she conceived since she wanted a baby so bad. I guess we'll learn all about that too this afternoon. Later: We had a wonderful lunch of bacon, lettuce, and tomato sandwiches on toast. We also had the last of the potato chips in the house. We won't have any more until we can go to the city and shop and that won't be until after the thaw in spring, some 3 months from now. "Kids," Mom began, "today we will begin extensive study on the human body specifically a woman's body and her reproductive system. Now, I already know that you know the mechanics of intercourse but there is much more to it and that has to do with pregnancy and contraception. Before we tackle the contraception phase you all need to know the mechanics of how a woman becomes pregnant. "When a girl goes through puberty, her breasts begin to grow larger and the nipples become more pronounced in preparation for a baby to suckle. She also begins growing hair under her arms and on her pubis. Her labia, inner and outer lips will become more defined and she will emit some fluids when aroused. She will also emit pheromones that the male nasal passage can detect and if there is an attraction then the fun progresses. "Now, I am going to give you some literature to read from the computer. You may have to wait for the weather to clear for the signal for access. When you do get it save the information to the computer for later study. For now, class is dismissed. I recommend that you get the board game "Life" and play it together. I'll be making a new board for you to play later. Enjoy." We played "Life" for about two hours when mom brought us the new board she had created. On it she had changed some of the squares that will make the game more realistic and fun. Cally won't be able to perform some of the tasks but we can make do should that happen. Here are some links to baby making and conception. Remember that these are how to conceive but can be used for prevention using the techniques shown. Two weeks from today you each will be tested with a 100 question test. If you all score 90 percent or better than I can be certain you fully understand the subject and can be trusted to use good judgment as you grow.

Feel free to Google or Bing search to learn more. Girls I suggest you begin charting your periods beginning today. Cally is first since this all new to her. Sara, you can pick yours up from your last period." Mom said. "I have a basal thermometer for you to use each morning. Just be sure to wipe it off with an alcohol swab before use. Now off with you. I have cooking to do." Nathan and his sisters continued to talk and play the game with the new board. Mom really did a nice job with the squares. Nathan could not wait for his sisters to land on some of them as he would be the beneficiary. Of course, he would love to land on a couple with Sara still available for fun time. Mom called the kids to dinner. Dad had called in on the radio that he would be camping at one of the campsites just a couple of miles from them. He had a fire and had caught some trout in the lake so he was very well nourished and warm. He was tracking a black bear that had come out of hibernation early. He hoped his trap would work since he would be sleeping. The loud cowbells he had attached to it would waken him when the bear was trapped. That night Sara and Nathan played mom and dad in bed. Mom had checked her calendar and determined that Sara was past her fertile time so they could engage in full blown intercourse. Artificial contraception devices were not in use in this family so they had only to rely on mother nature's method and common sense. Nathan and Sara quickly got naked and into a 69 position since they both loved oral sex with each other. Mom looked in on them as they made love. She was tired from the day's activities so went to bed. She did take a soothing bath and read while she soaked. Afterward she played with her pussy since she had no male to keep her company and she wanted Nathan to enjoy his sisters. She noted that she had some stubble so she took the time to shave herself. Shaving had a stimulating effect on her also. She felt so young when she took time to groom herself. She took the time to perfume herself before retiring to her bed. The radio was playing soft music as she fell asleep alone in her warm bed. "Nathan," She called, "would you please come to my bed for the night?" "Sure, mom," I replied. I kissed each of my sisters passionately and then grabbed a towel and went to mom's bed. When I entered her room, she was wearing a red negligee with red slippers. I was definitely overdressed. She came to me and hugged me and then kissed me passionately with lots of tongue. All through the kiss she was unbuttoning my shirt as I was unbuckling my pants. My penis was definitely confined by my lined jeans. She pushed me back onto the bed and pulled my pants off my legs. It was good thing I was only wearing moccasins in the house. I was still in long johns underwear though she was quickly stripping me naked. "Nathan, come let's sit in the hot tub for a while." I have always liked the hot tub especially when everyone is naked. I helped her out of her negligee and was pleased to see she was totally hairless below her head. I have always loved mom's little stomach pooch but tonight it was especially nice knowing she could very well be carrying my baby in there. I helped her into the hot tub and then stepped in myself. My penis was fully erect surrounded by my thick teenage pubic hair. As I sat down she reached over and took my balls in her hand and caressed them, rolled them around and tenderly made love to them. "I really love these." She said. "We will play and relax in here for a while then I have a surprise for you. I know you will like it and so will your sisters." "Mom, I thought hot water was bad for guys when they were trying to make babies." I said remembering what I had read. "Oh son, you are correct but I am well past getting pregnant now. If I am not already then it will be next cycle before you can try again. Tonight is strictly for our enjoyment and fun. I am totally in your hands but I will also be helping you. This is a continuation of classes begun earlier." "Oh Mom! That is so nice. I love your feeling me like that." I said quietly. She scooted over me and presented here breasts to me. I took one in each hand and began lavishing kisses all over them both. I squeezed her nipples as I kissed all around them. I really love her large areolae and protruding nipples that beg for my lips to grasp and suckle. I knew that someday they would be filled with her milk and my baby would be sucking on them just as I and my sisters had done when we were babies. I took one now in my mouth and gently bit the nipple giving her pleasure. She responded by squeezing my balls even harder giving me great pleasure too. She also was stroking my very stiff cock with her hand. My sucking became more forceful as she pleasured me. I gave each nipple and breast equal attention. "AHHHHHHHH!!!!" "Yeeeeessssss!!!!" "MMmmmmmmm" she responded as I made love to her breasts. I wished I had more hands so I could do more for her. I know she would love it if it were possible. Meanwhile we continued to bring each other to higher levels of passion and desire. "Ahhhhhh" I went as she squeezed me when she had a mini orgasm. I love it when she does that. We continued this way for nearly a half hour. I wanted to do more but the jets shooting water and our attention to each other was bringing both of us to very high levels of passion. I had her sitting almost directly on a jet that was pulsing and shooting water all around and in her vagina. Each time her clitoris was pulsed with water, she would "hmmmph" as the pleasure would overwhelm her. She tried to position me the same way but when the jetting water hit my balls it was painful. She did manage to get my butt hole on one of the jets and that was most pleasureful to me. I felt like I was getting squirts of water inside me as my anus relaxed. It was a very nice feeling. "Ding" the timer sounded. "Time to get out," mom said as she relaxed her grip on me. I held her still and gave a final suck to her nipples as the jets stopped and the water stilled. We sat there holding each other for a few minutes then I helped her up and out of the hot tub. She and I dried each other and then she said, "Take this towel and go lie on my bed." I obeyed knowing that she was going to make love to me now. Instead she brought dad's clippers and razor and gel. She clipped all of my pubic hair really close. Everything below my belly button and below the cheeks of my butt was clipped. Next she wet the entire are with a steamy hot towel and applied shaving gel and the shaved all the hair from my pubes, cock, and balls. She turned me over and then shaved my butt cheeks. I have to admit I really liked the result. It makes my cock appear much larger and I knew my sisters, especially Cally, would like my looking like her bare peach. After I was all dry mom then applied a soothing cream to combat razor burn. "I'll shave you every other day until you learn how to do it yourself." She said. "Your sisters may even want to help too." She added. She then climbed onto the bed and me, straddling my waist positioning herself for penetration by my very hard cock. She worked her hips so that she spread the wetness all around and then began finding just the right position. Once she found that position she slowly lowered her pussy onto my cock. I could feel me slipping deeper and deeper into her clasping hot cavern. When I finally bottomed out I could feel her cervix touching my cock slit. It felt hard and stiff. It was not at all like an earlier time when we coupled. It was very soft and pliable then. I then understood what the books said about that. She continued to rise up and down on my shaft as I licked and sucked a nipple when it touched my mouth. "Mom, you feel so much different this time. It's so tight and gripping on my cock head." I muttered as emotion overtook me. "Yes son, I expect it is different. I am no longer ovulating and your now bare skin is more sensitive than before. I expect that next week I should know if your sperm took. I sure hope so. It would make your dad and I so very happy." She whispered as I suckled on a firm nipple. I could feel that exquisite feel bubbling in my balls just before they draw up and release their load of sperm. My cock began to swell. It seemed to me to get way larger than ever before. Mom noticed it too as she pressed lower to gain all of me inside her. My cock slit was now nuzzling her cervix. I knew I would be blowing right at it but what I didn't know was that it was now blocked with mucous and no sperm could enter her baby making area. It would be for naught, just our pure pleasure. "AHHHHH!!!!" "OHHHHHHHH!!!!!!" She moaned as her muscles tightened and squeezed me just as I exploded within her. "ARRRRRRGH" "ARRRRGH" as the pain of the shooting reached my brain. I pressed up as my balls emptied, with some pain. I guess they have been too active recently and need some rest. My internal tube must need rest since the friction seemed to cause me pain. "MMMmmmmmmm!" Mom moaned as her orgasm hit her and she collapsed on my chest. I hugged her close and caressed her back. Our love was complete. It was as complete as any two lovers could be. I had brought her pleasure and delivered my payload into her. Time would only tell now how our lives would change. More to come in part 5
