The Talk WARNING!: This story contains spoilers for future episodes of the "Life With Charlene" series. If you do not wish to have future storylines for that series spoiled ahead of time, please stop reading now or skip ahead in the story to where Eddie and Ellie return home from school. Nearly two months have passed since Charlene, Eva, and I went on our annual camping trip in Northern Minnesota. While we were gone, I ended up mating with both my sisters while they were in their ninetales forms and receptive, getting both of them pregnant in the process. Both Eva and Charlene are nearly full-term with the pups I provided them with, each of them proud to be carrying vulpix pups. In her womb, Eva carried fraternal twin female pups, ones that she decided to name Autumn and Kari. Meanwhile, Charlene turned out to be even more productive. Her uterus was filled with four vulpix pups, two identical twin females, another non-identical female, and the only male pup I produced between my two sisters this time around. It was late in the afternoon and the weather outside was typical for northeastern Mason Island standards in Late March. It was about 70 degrees outside, with bright sunshine, and the foliage starting to show color again as the winter came to an end. Compared to the winters in Minnesota, the winters in Mason Island were rather tame, we didn't get much in the way of snow in Familia and the air temperature almost never dropped to or below zero. It was more like a winter in a place such as Alabama or Tennessee than a winter that Charlene and I were much more familiar with. Things were a bit busy on this Friday afternoon at the house. Eva was up in her room having a nap after she spent all morning out with Melissa at the Familia/Twin Lakes Shopping Center. They spent the morning shopping for things that Autumn and Kari would need once they came into the world. At the same time, Charlene was busy in our kitchen, preparing a dinner consisting of ham mixed in with scalloped potatoes and cheese sauce like our mother made sometimes when we were living at home. In addition to the pending birth of the four pups she was carrying, another important event would soon be happening in our household. Our oldest pups, Eddie and Ellie, were about to turn 10 years old. We already planned on having a birthday party for the two of them, much like the one Charlene and I got when we turned 10. Although, when Sis and I turned 10 it also happened to be our "golden birthday", but that wouldn't be the case for Eddie and Ellie...they had a couple more decades before they reached that milestone. While Charlene was busy in the kitchen, preparing some fresh vegetables to go along with our dinner, I came up behind my twin sister and put my hands around her large pregnant belly, rubbing it a little bit. "So, how are you doing, Sis? Are the pups behaving themselves in there, or does it feel like they're about ready to come out?", I asked while touching my sister's belly, causing Charlene to briefly stop what she was doing, placing a hand on one of my own. "They're fine...I think it'll be a few more days at least before they're ready to see their mommy and daddy from the outside", Charlene commented before letting out a sigh, thinking about something that happened to us in the past. "You know, the more I think about how warm and frisky our little ones are inside me, the more I can't help thinking about Valerie. I really miss her", Charlene added as I leaned in closer to her and rubbed my nuzzle along her neck. "I know what you mean...I miss having her around too...and Satoshi", I answered back as I tried my best to fight my emotions on the inside. The relationship that Charlene and I shared with Valerie ended under tragic circumstances, and along with her went one of the first pups that I helped create. Valerie's memory would live on, though, as one of our identical twin daughters was to be named Valerie in her honor, with her identical twin sister being named Kirara (after Valerie's cousin, who is alive and well and now living in Familia*). As for their other sister and their brother, Charlene and I picked out names for them as well. I thought about naming our son Satoshi, but Charlene wanted to give him a name that was more personal to both of us, so we decided to name him Marshall after one of our grandfathers. The other female pup was to be named Victoria, though Charlene and I both agreed to call her Vicki. Charlene started to murr while we were together in the kitchen, with my hand and hers touching along her belly, rubbing it together as we both felt our little ones move around inside Charlene's uterus. Compared to the belly that Sapphire usually had while shi was pregnant, Charlene's belly was small, but considering that this was one of her largest litters thus far, it was large for her. "I think after these ones come out we should take a break from having more pups for a while...at least until Eddie and Ellie move out of the house", Charlene commented while I kept nuzzling her gently. "Yeah, I see what you mean. I'm sure it would be easier if you had the same abilities as Sapphire does for giving birth, but I don't know if you'd be able to learn that from hir", I mentioned to my sister while touching her belly some more. "You know that I'll be by your side when our pups are born, right Sis? I wouldn't want you to go through labor alone", I added, thinking that maybe she told me what she mentioned because of the large litter inside her womb and that she was not looking forward to a long and painful birthing process. Charlene turned to face me, touching her nose to mine and placed her hands on my cheeks. "That's not quite what I meant. I already know that you want to help me when I need it", Charlene commented before she gave me a kiss on the lips. "What I really meant was that we shouldn't be so quick to have so many pups together at one time. We're not even 40 yet and we've already produced four litters together, including these ones. I've got a lot of fertility left in me, so there's no rush for us to make them", Charlene added, referring to the fact that as a kitsune vixen, Charlene's reproductive life was much longer than that of a normal Kapernian vixen. A typical 39-year-old vixen would have about five years of fertility left in her, Charlene (and for that matter, Eva) had several hundred years of fertility left. However, I couldn't help making a smart-ass comment of my own when Charlene mentioned that she was in no rush to have a big family from me. "Says the vixen who begged me to impregnate her just a few weeks ago when she became a ninetales for the first time!", I playfully answered. "Hey! You're the one who promised me that you'd give me vulpix pups when I became a ninetales, remember?", Charlene responded promptly in an equally playful tone, knowing that I was just having a little bit of fun with her. I placed my arms around Charlene, pulled her close to me and kissed my sister on her lips. "Let's not argue about this any longer, Sis. When you're ready to have more pups after these ones, I'll give you more. All you have to do is say the word, and we'll make them", I mentioned after the kiss in a soft and loving manner. Charlene murred to my response and nuzzled against me while we held each other tight for a few moments. After this, Charlene went back to what she was doing before, finishing with the vegetables for dinner while I went back towards the family room, having a seat in one of the movie-theater style chairs that we had put in. Not long after I sat down the front door opened, and I heard two familiar voices talking from where I was in the family room. ***For those of you who wanted to read this story and avoid the spoilers for the "Life With Charlene" series, it is now safe to do so...*** Every school day, at a little bit past 4 PM, Eddie and Ellie returned home from Familia Elementary School. They were in 4th grade now and nearing that point in their lives where they would start growing up in earnest. However, they still had a couple of years before they started to become sexually mature, and they still seemed oblivious about what sex was and how they were made. They knew where they came from, but they knew nothing about how they got there. They also had no idea that their mother and father were siblings themselves. In the comfort of our house, Eddie and Ellie behaved a lot like how Charlene and I did when we were their age. They shared the same bed, with Eddie usually snuggling with and humping his sister at night as they slept together, much in the same manner as I did to Charlene when we were growing up and sleeping together. Eddie may not have known what sex was, but there was still some biological instinct in him, this combined with the love he had for his twin sister to encourage the young male to rub against Ellie as they slept together. Of course, while Eddie was able to get erections from being with Ellie, he could not produce semen, at least not yet. It likely would be a couple more years before they were old enough to attempt mating together, if they wanted to do so, that is. Outside of the house, Eddie and Ellie behaved a lot like a normal brother and sister. Although Familia was a lot more open to incest than where we came from, there were still some standards established for the town, especially considering that not everyone who lived in the town practiced incest. Some were residents from the old town of Twin Lakes that stayed behind once we saved their town, and others moved from other parts of Mason Island to take advantage of the town's rapid growth over the last several years. There were some other customs that were kept from the days of Twin Lakes as well. For example, the old Twin Lakes/Campbell district had a policy requiring school uniforms for all students. Charlene and I thought this was stupid, considering that we never had to wear uniforms while we were in school, but the citizens demanded the uniforms be kept as a mandatory policy. Neither Eddie nor Ellie were particularly happy wearing the uniforms. They would rather wear normal clothing to school, and Charlene and I couldn't blame them. Still, unless they were to go to a different school district, or if Charlene and I decided to found our own private school that operated independently from the Familia/Twin Lakes/Campbell school district, they had little choice about it. It bothered Ellie less than it did her brother, considering that the dress she had to wear to school was light blue in color, plus she still got to wear her light blue hair ribbon. Eddie, on the other hand, didn't like wearing the tan-colored khakis, blue polo shirt and white tie. He felt as if it made him seem older than he really was. When they came home, I got up from the chair I was sitting in and went over to greet them as they walked by the family room. "Hi Eddie...Hi Ellie!", I called to the pups in a cheerful manner, getting them to come over to me as they often did. They both embraced me in their arms with Ellie touching her nuzzle against the side of my own. "Hi Daddy!", Ellie answered cheerfully while nuzzling me as Eddie wasn't quite as affectionate with me as his sister was. I knew that he still loved me, it's just that he wasn't as willing to nuzzle me like Ellie. I let them bond with me for a few moments before they eventually let go. "So...what did you two learn about in school today?", I asked curiously. As soon as I asked this question, Eddie and Ellie looked at each other, then looked back at me. "Dad, can we ask you and Mom a question?", Ellie responded in a curious tone. When Ellie asked the question, I looked towards the kitchen and saw Charlene in the middle of preparing dinner, I felt that she was too busy at the moment to talk to them. "Well, I think Mom's a little busy right now. However, you can ask me your question and I'll talk to her later when she's not so busy", I answered. Eddie and Ellie looked at each other and started to whisper into each other's ears, apparently trying to figure out how they wanted to say what they wanted to say. I saw this from them many times before, usually before they were about to ask me or Charlene for something. That is what I assumed they were going to ask me about; I was not prepared for what actually came out of Ellie's mouth next. "Dad...you remember how you and Mom told us that we came from inside Mom's belly? How did we get inside Mom in the first place?", Ellie asked in a curious tone with Eddie standing next to his sister, their bright blue eyes looking up at me. I felt my tails become stiff and my fur stand on end, with sweat beginning to form on my forehead. "That's...a very good question...Ellie", I stammered nervously, taken by complete surprise over her inquiry. "Why don't you and your brother change and get washed up for dinner, then go wake your aunt Eva from her nap when you're done. Mom and I can talk about how you got inside her later", I suggested to the pups, thinking that I could buy some time for Charlene and I to talk it over. They did as I asked and ran upstairs to their bedroom, while I made my way into the kitchen to speak with Charlene. When I got to the kitchen, Charlene was just finishing with the platter of vegetables to go with dinner, a platter consisting of carrot sticks, celery sticks, radishes, cucumber slices, and green olives for the pups. The inside of our kitchen was almost as large as our family room. It had a gas-powered stove, two separate refrigerators (one for food and one for beverages), a microwave oven over the stove, a dishwasher, an ice maker, and a kitchen island where most of the food was prepared. "Sis, we need to talk", I promptly told my sister while she was putting the vegetables in the fridge, so they'd stay cool until dinnertime. She turned around to face me, placed her hands on my shoulders and touched her pink nose to mine. "Sure...I've got a little bit of time before I need to take the potatoes out of the oven. What's on your mind?", Charlene asked, possibly thinking of something sexual in nature. In the past when I impregnated Charlene, she always seemed to become more eager to mate when she was near full-term with the pups she carried. I wasn't sure why this was the case, but I wondered if it had something to do with hormones. I did my best not to get turned onto Charlene right now and focused on what Ellie told me. "I think it's about time we had 'the talk' with Eddie and Ellie", I mentioned as Charlene's eyes opened wider and I watched her mouth hang open for a few seconds. "You mean, they asked you what it was like to have sex?", Charlene asked in a nervous tone, beginning to sweat a bit before I placed my arms around Charlene's upper body and held her close to me. "Well, not quite...Ellie actually asked me how she and Eddie got inside you. However, I still think we need to have this discussion with them. They're almost 10 now, it won't be long before they start puberty and getting sexual urges of their own...like how we did", I explained to Charlene. Charlene knew what I was getting at, and it was a bit of a surprise that they didn't ask about how they were made long ago. Eddie and Ellie knew that males and females had different parts underneath their underpants, but they didn't know why that was the case. By the time Charlene and I were their current age, we already knew plenty about sex and reproduction. "You're right...it is about time for them to learn about sex", Charlene responded before a thought came into her head. "But, how are we going to teach them? We both agreed not to have sex with our pups, especially while they're under 18", she added, referring to the agreement we made long ago before Eddie and Ellie were born. I held my sister tight and gave her a nuzzle. "I don't think we need to worry about them wanting to have sex, at least not for a little while longer. We can just explain to them how it's done and see how things go after that", I suggested. "We'll talk to them about it this evening, once the younger pups are in bed", I added, thinking that this would be something that needed to stay between us and our oldest pups. Charlene agreed to my suggestion and everything seemed to be in order. After this, I stayed close by for a little bit to assist Charlene in getting dinner ready. She had everything under control as far as the cooking was concerned, but she needed help getting the dining room table set up. Several Hours Later (in the master bedroom)... After making sure all the younger pups were asleep for the night, Charlene and I asked Eddie and Ellie to join us in our master bedroom. We didn't know exactly how much they knew about sex, so we figured that we'd start by asking them. We also figured that it was possible that they might need some visual aids to help them understand a little better, so Charlene and I wore our robes over our otherwise naked bodies. We would only take them off when and if we felt it was necessary to do so. The inside of our master bedroom had walls painted navy blue, with a ceiling fan above. The bedroom contained light-blue carpeting on the floor, and lilac-colored sheets and pillowcases on our king-sized Comfy-rest mattress. The bedroom had an attached bathroom with a shower and a jacuzzi big enough for up to three. In one corner of the bedroom, next to the walk-in closet, there was a dark brown dresser which had our shirts, pants, and undergarments in it below a mirror. On top of the dresser there were several pictures of Charlene and I through the years, going all the way back to when we were 4 years old. A few of the pictures had Melissa in them, and a couple of them had Sapphire in them. One of the pictures we had on the dresser was of Eddie and Ellie just after they were born, snuggled up to their mother. We had other pictures of Eddie and Ellie, as well as our other pups on the wall on the opposite side, leading up to the attached bathroom and another doorway that led to our computer room. On the wall facing the bed, there was a 75-inch Super HDTV on the wall, complete with a home entertainment cabinet underneath the TV, which held all of our various media players and game consoles, along with a "master switch" at the top of the cabinet that allowed us to change devices with the push of a single button. Melissa, Eva, and Sapphire all had their own rooms that looked similar to ours, with some variations in the decor and amenities, depending on the wishes of the occupant. For example, Sapphire's room had purple-colored walls, lilac-colored carpeting, and white bedding, though everything else in the bedroom (aside from the personal pictures) were pretty much the same. Eddie and Ellie soon arrived in the bedroom, dressed as the normally would be for bed. They were a bit too old to be wearing pajamas, at least in the traditional sense, so we gave them a choice of things to wear for bed. The only requirement that we had for them was that they had to wear underpants, they could not sleep naked together...at least not yet. Eddie wore one of my old Twins T-shirts that I stopped wearing a couple years earlier and Ellie wore a light blue nightgown that covered her body. "Why don't you two have a seat on our bed and we'll explain how you two were made", Charlene commented to our pups as they came into the room. Eddie and Ellie did as they were told, climbing onto the bed and sitting at the foot of it, sitting together as they often did. Every once in a while, one of us would catch Eddie and Ellie touching hands or with their tails intertwined, showing their true feelings for one another, acting much like Charlene and I would when we were their age. However, they didn't do this tonight, they seemed more curious to learn at that moment. "So...as the two of you have already noticed, there are a few differences between a male and a female", I began to explain, referring to an earlier discussion from several years ago when Eddie asked why his sister didn't have a sheath like he did. That was an awkward discussion to have with him then, but this one might prove to be even more awkward. "You see, the reason why males have a penis and females have a vagina is because they need them in order to make babies", I continued as Eddie and his sister looked at each other, both of them seemed to be a bit puzzled. "But Dad, I thought you told us that babies came from inside females. How can a male make babies?", Ellie curiously asked as I started to sweat a little and feel a bit nervous. Thankfully, Charlene helped me out by answering Ellie's question. "Because honey, babies do come from females...but they cannot have them alone. They need a male to help them start growing first", Charlene explained to Ellie in a calmer tone, causing our son and daughter to scratch their heads a little. "OK, but how does a male help a female make babies?", Ellie asked, unsure about how a male and a female could produce babies. It was at that time we knew that a demonstration was in order. "Your mother and I were hoping that you'd be a little older before we had this lesson", I explained while undoing the fabric belt on my robe. "However, it would seem like you two need to see how it's done, so we're going to show it to you", I added, removing my robe while Charlene was doing the same. "Now, we're going to tell you some things about your bodies that you probably haven't learned yet. So, don't be surprised when you hear your teacher talk about this soon", Charlene added as she removed her robe, letting it drop to the floor. Soon, Charlene and I were naked, with Charlene's heavily pregnant belly protruding outward a considerable distance and moving a bit as our pups moved around inside her uterus. "You see, this is what grown-up male and female foxes look like", I began to explain as we let Eddie and Ellie see what we had under our clothes as they looked on curiously. "Normally your mother's belly isn't as big as it is now, but that's because she has your brother and sisters growing inside of it right now", I added. Both Eddie and Ellie knew that Charlene was pregnant with their younger siblings and were getting eager to see them. "Your father and I made them together about a couple months ago and they're almost ready to come out", Charlene mentioned as Eddie and Ellie both got up from the bed and went to her. They curiously touched at her belly a bit, making the vulpix pups inside Charlene move around, tickling her in the process. "It seems like your baby brother and baby sisters are getting a bit eager to see the two of you", Charlene commented in a soft tone, letting Eddie and Ellie touch her a bit. As they did, Ellie asked another question. "How do the babies get out of you when they're ready to be born? Does a doctor have to cut you open and take them out?", Ellie asked, unsure on how birth worked. Charlene brought our oldest pups back over to the bed and had them sit down again. "Hopefully not, honey. A doctor only has to do that if they don't come out the natural way", Charlene mentioned. "Anyway, when it comes time for a mommy to have her babies, she goes into something called labor and they're pushed out from inside her", Charlene continued as Ellie seemed to squirm a little to that thought. "I know, it's not exactly a pleasant experience. However, it gets easier the more you do it, and it feels rewarding to hold your newborn pups for the first time, feeling them nurse from your breasts and listening to them softly murr as they snuggle against your body", Charlene continued. It was at this time when Eddie started to have questions of his own. "Mom...how do you push the babies out when they're ready?", he asked curiously with his sister soon joining in. "Yeah, and you still haven't told us about how our brother and sisters got in you to begin with", Ellie added, both pups seeming eager to know more about how sex worked. They kept badgering us with questions until I felt like I needed to settle them down. "Alright you two, calm down. Now, your mother and I are going to show you how babies are made. However, before we do, we need to show you a few things about your bodies", I mentioned before turning to Charlene. "Charlene, why don't you get up on the bed so they can see your 'you know what'", I commented to Charlene softly, not wanting Eddie and Ellie hear what I was saying before I turned my attention back to the pups. "Eddie, Ellie, why don't you two come over here with me for a minute so that Mom can show you what a female has", I suggested to the pups as they curiously followed my instructions, coming over to stand with me. It was at this point when they started to hold hands with each other. Meanwhile, Charlene climbed onto the bed, relaxed on the mattress and opened her legs a bit. Her belly was swollen to the point where none of us could see her face from where we were standing, but not swollen enough to prevent Charlene from reaching her vixen parts to educate our pups. "OK, now pay close attention", Charlene commented as she placed her hands down around her outer vaginal lips and opened them up, revealing her vulva to both of the pups. "Do you see the hole down there? This is where you and your siblings came from. The hole is connected by a long and muscular tube called a vagina that pushes the babies out when they are ready to be born", Charlene started to explain. The vagina connects to a place called the uterus, where the babies grow inside their mother until they're big enough to come out", Charlene continued as Eddie and Ellie both watched curiously. "Ellie, you also have these parts, but you're not old enough to start making babies", Charlene mentioned to Ellie as her explanation seemed to answer some of their questions. Eddie and Ellie looked at their mom's vaginal opening and passage curiously, with them noticing how it looked on the inside. "It looks all pink...and slimy", Eddie commented, seeing that Charlene's vaginal folds were a bit damp from the juices she produced. "That's just the way a female's body is when she's old enough to start making babies, Eddie. Ellie's will be a lot like this when she's old enough, but that won't be for a few years", I told my son while Ellie moved closer to where her mother was and got a look inside the same vaginal passage she came out of. She seemed to understand where they came from and how they got out, but there was still one big question remaining. "Yes, but how did Eddie and I get inside you in the first place...and what does Dad do to help make the babies?", Ellie asked curiously. I wasn't surprised by Ellie's question, but I needed to think of a way to explain it so she could understand better. "Ellie, do you know how plants are made?", I asked curiously, thinking that she might understand this a bit more since I knew that they were taught about how flowers were pollenated by bees and such to make new flowers. "Sure, a friendly bee comes along for a drink of nectar and pollenates the flower. Then, after a little while, the plant produces seeds", Ellie answered confidently before getting a little puzzled. "But what does that have to do with you and Mom? You're not flowers...you don't need to have a bee to come along to make babies...do you?", Ellie soon asked, only partially understanding what I was getting at. I came over to Ellie and put my hand on her shoulder while Eddie stood next to me. "No honey, we don't need bees to make babies", I explained to my daughter before going into more detail. "However, your mother still needs to be 'pollenated' before she can get pregnant", I added as Ellie looked at me curiously, still not understanding. "You see Ellie, you, your brother, and all of your siblings started out as tiny little eggs inside your mother's body. They're so tiny that you probably wouldn't be able to see them with your own eyes", I tried to explain to both of the pups. "Each egg contains half of the information needed to make a baby, but it needs the other half from a male", I explained as Eddie seemed to understand. "Oh, I think I get it. You put your pollen inside Mom, and it meets with her eggs to make babies!", Eddie exclaimed confidently as I put my hand on my son's forehead and rubbed it a bit. "Well, close enough. Actually, the 'pollen' that males produce is called sperm. They look like little tadpoles that are even smaller than a female's egg. They swim around inside a female's body until they find an egg and then bond with it, once a sperm meets with an egg a baby can start developing", I explained. Eddie seemed to understand reproduction a bit better than his sister but was still inquisitive. "Does this mean that I have those tadpoles inside me?", Eddie asked curiously. I rubbed my son's forehead some more and made him murr a bit. "Well, not quite yet. You've still got a few years before you start making sperm. However, once you are old enough, your body will be able to make it just like how I'm able to", I answered. While Eddie seemed to be doing well in the learning department here, Ellie seemed to be confused as well as a bit disturbed. "Eww! I don't want to have any yucky tadpoles inside me! That sounds really gross!", Ellie commented in disgust, thinking that the tadpoles were like those that became frogs or something like that. "Ellie, they're not real tadpoles, they just look like them...and they're so small that you need a microscope to see them", I assured my daughter before Charlene had something to add. "Honey, when you're old enough to start making babies you'll learn that it's not as disgusting as your father made it sound. It actually feels quite warm and pleasant whenever your father puts his sperm in me, and his 'tadpoles' tickle against my insides as they swim to my eggs", Charlene mentioned to Ellie. "Trust me, you'll understand a lot better in a few years", she added. We could tell that Ellie was still unsure about having something that resembled tadpoles inside her, probably because she wasn't quite mature enough to understand what it felt like to have sex. Once she tried it, we were certain that she'd understand how Charlene felt whenever I inseminated her. However, the questions weren't done from the pups. "Dad...where do the sperm come from...and how do they get inside Mom?", Eddie soon asked, still eager to learn more about the differences between males and females. "Oh yeah, I suppose I did neglect to explain about that!", I answered promptly as I moved one of my hands down towards my sheath and touched it. I didn't rub my palm across the sheath, at least not yet, but I was getting ready to do so. "Anyway, much like how females have body parts inside them that make and store eggs, males have body parts that make and store sperm", I mentioned as I pointed with my free hand down towards my testicles. "The sperm live and grow in here until they are ready to be put inside a female and 'pollenate' her eggs", I explained as Eddie and Ellie looked at my crotch, and then Eddie looked at his own. "But Dad, why don't I have those?", Eddie asked curiously since he had yet to reach the point where his testicles descended into his scrotum. I used my free hand to pat my son on the forehead. "Don't worry, son. You have them inside you, they're just not ready to make sperm yet", I assured Eddie. "Give it a couple more years and yours will look a lot like mine", I added before switching to Eddie's other question. "Anyway, about how they get inside your mother...well, in order to get the sperm into a female, a male has to put something into her vagina", I commented somewhat nervously, unsure if I really should let Eddie and Ellie see my erect penis. The two pups listened curiously and seemed to want to know more about sex. "What do you put inside Mom to make babies, Dad?", Eddie asked. "Yeah, and how do the babies come out when they're ready to be born if you put something in her?", Ellie added, making me sweat a bit more as Charlene got up from the bed and came over towards me. My sister placed her arms around my body and grabbed hold of my sheath, stroking it lightly, enough to cause my maleness to start emerging. As she did this, Charlene whispered into my ear. "I think we're going to have to show them how mating is done. It's the only way that they'll understand how sex works", Charlene suggested as Eddie and Ellie watched this going on, both of them noticing my foxhood growing to Charlene's touch. "Whoa! Something's coming out of Dad's sheath!", Eddie exclaimed as he watched me growing sexually aroused as Ellie looked at my maleness and seemed a little curious as well. "It looks all red and twitchy...and I see a little bit of wet stuff coming out of the tip", Ellie mentioned, noticing my growing arousal. Then, my knot came out of the sheath, with both of the twins noticing it. "What's that?", Ellie asked curiously, pointing to my bulb. Because I was a little busy enjoying my sister's touch, Charlene explained it to Ellie. "It's a little something that all fox boys have on their penises. It makes mating a lot more fun and productive when they do it in certain positions", Charlene mentioned calmly. "When it gets put inside a female and becomes excited, it grows much larger, causing the male and the female to be stuck to each other for a little while", she continued as Eddie and Ellie looked curiously at my fully erect penis, with Ellie actually reaching out to touch the knot. When she did, I felt my shaft twitch a little as it was already sensitive to touch. "Ahh, please don't touch me there, Ellie. It's really sensitive to touch, and I think it wants to go inside your mother again", I mentioned, seeming eager to mount Charlene and mate with her in the same way I did when Eddie and Ellie were conceived. Charlene soon wrapped her hand around my bulb and gave it a firm squeeze, causing me to yip briefly before she nuzzled against my cheek. "Well, I think we still have a few days before their brother and sisters are ready to come out, so I guess I can take it in me for the sake of educating Eddie and Ellie", Charlene coaxed in a soft tone, murring a bit as I felt her hand continue to grope at my throbbing knot. By now, the precum trickled from my tip freely, catching Eddie and Ellie's attention as the curious vixen pup asked more questions. "Are those the tadpoles that you were talking about?", Ellie commented, seeming a bit puzzled as she couldn't see them. "Ahh...it's a little something like that, honey. It's actually a little something that daddies make before they put the tadpoles inside mommy to help them get to her eggs", I explained as best as possible while Charlene continue to rub and grope my maleness. It was becoming a lot harder to ignore my instincts. I knew Charlene wanted sex and I could detect her aroma filling the room. If Eddie were producing sperm he'd be able to sense his mother's sex scent, but since he wasn't he could smell anything of that sort. "Are you and Mom going to make more brothers and sisters for us now?", Eddie soon asked as he watched his mother touching and holding my bulb, making my entire foxhood twitch excitedly. Charlene released her grip around my length and took a moment to answer his question. "No honey, I already have some inside me. Once a female has pups inside her she can't get pregnant again until after the ones she already has come out", Charlene explained as I felt like I needed to add something. "Well, except for your aunt Sapphire, but that's another story", I added. "Anyway, your mother and I are going to show you two what it's like to mate. So, why don't you two have a seat on the bed and watch. That way you'll know what to do when you two are big enough to try it", I explained to Eddie and Ellie as the curious pups did what I told them, hopping back up onto the bed and taking a seat at the foot of it. Meanwhile, Charlene got down on the floor, getting on all fours and raising her twin tails over her back. "There are many different positions when it comes to having sex, but we're going to show you the one that is our personal favorite", Charlene explained as I looked at her backside and saw how her vaginal lips looked glazed with her sauce. "It's called foxy-style, and it is how male and female fox couples usually mate", she added while I came close to her. Eddie and Ellie watched curiously, seeing the tip of my erect penis touch against their mother's vaginal lips, rubbing against them a little as I was on my knees behind her. "Eddie, when a female is positioned like your mother is right now, you take your erect penis and place it up against her opening like this", I explained to my son. "Then, once you have it in place...", I continued just before covering Charlene, wrapping my arms around her lower body, grabbing hold of her hips. "Ahh...you push it forward, letting it slide into her vagina", I added, inserting my shaft into Charlene, feeling the warmth and wetness of my sister's canal around my flesh. "You keep pushing forward until you have everything except your knot inside your partner and keep it still for a few seconds", I mentioned to the pups, feeling Charlene's folds contract around my flesh, giving it a nice squeeze. "Mmm...that way you can really appreciate how good it feels to have your mate hugging your penis once it's inside her", I added. Eddie seemed to get into the scene in front of him as his twin tails swished around a bit. It wouldn't surprise me if he were developing an erection of his own underneath that shirt he was wearing, though it would be some time before he would be interested in having sex himself. Meanwhile, Ellie still seemed a bit more apprehensive. "But, what does it feel like for Mom when you put it inside her?", Ellie asked, seeming to want to know what to expect for her first time. "Ahh...it feels rather strong and twitchy...and the sticky stuff that your father puts in me feels warm as it touches my insides", Charlene mentioned. "Of course, it feels even better once your father starts moving in and out of me", Charlene hinted, suggesting that she wanted me to begin humping her. I got the message and began to move in and out of my sister's hot vixen hole, feeling her walls massage my length as I moved at a modest pace. "Mmm...you see, one of the best parts of mating is when you and your partner feel your genitals rubbing together. It feels hot, ticklish, and exciting", Charlene told the pups while I was enjoying her. "Mmm...of course, you don't want to go too fast when you do it, especially your first time. You want to take things nice and slow to begin with, that way you get to savor the feeling of how it feels to mate", I added as the sounds of our genitals squishing together began to become noticeable thanks to the juices that Charlene produced from her insides. "Eddie, you'll also need to make sure that your partner is good and aroused before you mount her. She'll need to produce lots of vaginal juices to make it easy for you to slide through her passage, and more comfortable for her to receive your penis", I explained to Eddie before Charlene had something she wanted to mention to Ellie. "Ahh...although it can be a bit difficult for you to receive a penis inside you for the first time, Ellie. Your vagina is not yet used to having anything inside it, so there might be a bit of discomfort when you decide you're ready to have sex. However, it will go away after a little while, as long as your partner is patient, and you'll be able to enjoy it a lot more after that", Charlene explained to Ellie as I had a thought of my own. "Mmm...it would probably be best that you two tried doing it with each other once you're both ready to have sex. That way you'll both be doing it with someone who loves you and you know you can trust", I suggested. As soon as I mentioned this, Eddie and Ellie looked at each other, then looked back at what I was doing with Charlene. "You want Eddie to do what you're doing to Mom to me?!!", Ellie exclaimed. I tried to keep my thoughts focused on mating with Charlene, moving my throbbing maleness through her tight and warm vixen hole, but also figured I should answer my daughter's question. "You don't have to do it right now, Ellie. In fact, it's better if you wait until he's making sperm and you're able to produce eggs", I answered my daughter as I started to feel the churning inside my testicles grow stronger. "Mmm...besides, we know that you love your brother. Mating together can be a good way of showing Eddie how you feel about him", Charlene mentioned as I felt her passage spasm around my length, gripping it a bit tighter and coaxing me to hump my sister at a slightly faster pace. "Don't think we haven't noticed what you've done in bed with your sister, Eddie. We've seen you licking her neck from behind and humping against her while you two have been sleeping. We know you have deeper feelings for her that you haven't shared with Ellie", I continued as I started to grind my knot against Charlene's outer lips a little more, starting to move from side-to-side a little as I mated with her, getting closer to inserting my pulsating bulb into her hot passage. While I continued mating with Charlene, I looked over to the bed and noticed that Eddie and Ellie were looking at each other again, this time with Ellie blushing a bit. "Do you really love me Eddie...in the same way that Dad loves Mom?", Ellie softly asked her brother as he started to blush some. "Yeah, I've been in love with you for quite a while. I've always enjoyed playing with you, cuddling with you at night, and thinking about all the times we used to play house together. You make me feel happier than any of the other females in our class", Eddie mentioned to Ellie. The vixen pup listened to her brother's words and soon smiled, pouncing on top of Eddie and knocking him to the bed. "Do you want to know something, Eddie? I've been in love with you, too. I always loved the way you cuddle with me and lick my neck when we're in bed. You're the best brother I could've asked for!", Ellie told Eddie happily, going as far as to place a kiss on Eddie's lips, doing so for several seconds. It was likely the first kiss from a female his own age that he ever received, and it made his ears stand straight up and his tails coil together. It also caused Eddie's penis to unsheathe, poking against his underpants from underneath his shirt, touching against Ellie's crotch. When this happened, Ellie seemed to understand a bit more about why males and females mated together. She soon turned towards us while still on top of her brother, watching as I was humping Charlene at a moderate pace, pushing my knot closer to her vaginal opening. Charlene leaned back against me some, murring to the rubbing she felt inside her, sensing my precum covering her cervix. Unfortunately, because it was plugged, none of the precum made it into her uterus, but she could still feel the warmth of my precum spreading throughout her vagina. "Mom...what does it feel like inside when Dad mates with you?", Ellie asked curiously, seeming more interested in sex than she was before. Charlene had a bit of difficulty answering Ellie, she was too busy panting and moaning to having me in her vagina and feeling her pups moving around in her womb at the same time. "Mmm...it's like a hot, rubbing sensation Ellie. It feels like your insides are getting massaged while warm and sticky goo gets pumped inside", I answered for Charlene, thinking that this was something like what she would tell Ellie if she could speak. "However, that's not the best part about mating...the best part is when your partner makes you feel so good on the inside that you feel your insides erupt...mmm, just like what I'm about to do to your mother", I mentioned as I gave Charlene my full attention and effort, humping her as if she were receptive again, moving from side-to-side as I did so while my bulb kept pushing closer to her. The churning within my balls grew intense and the heat within Charlene's folds grew much stronger as she tightened around me in anticipation of my bulb going in. Ellie watched curiously as Eddie was able to get up and crawl over towards the edge of the bed, watching with her sister as they held hands. It was clear that they now wanted to mate together, but it was still a bit too early for them to act on these new feelings. Finally, Charlene was able to speak again as she had something she wanted to add. "Actually, the best part of mating is when your partner makes you orgasm while he...does...the...same...thing...inside...", Charlene began to explain, just as I felt my bulb pass through Charlene's entrance, becoming engulfed by my sister's tightness and warmth. "Ahhh...yes-s-s-s-s!", Charlene exclaimed cheerfully as she reached her climax, sending waves of hot and spicy smelling juices flooding through her passage as her walls converged on my knot, hugging it firmly while it started to grow. Not to be outdone, I came for my sister, injecting hot spurts of my foxy cream against her vaginal walls and cervix. "Ahhh...see this kids? When you can make each other feel like this, you'll know that you've found someone you want to be mated to for life", I commented as I sent bursts of my semen deep into Charlene. I felt a little bad about having it go to waste like this, it would've been nice if we could've given the pups a lesson on how they were conceived and how pregnancy worked. "Of course, Mom and I aren't anywhere near done yet", I soon mentioned, feeling my bulb become locked inside Charlene. Eddie and Ellie seemed to be puzzled after watching us mate, wondering what else could be left after they saw us climax together. "Eddie, when you and Ellie are old enough to mate together, and when you put your knot inside her, it will grow much larger and become stuck. You won't be able to pull it out, not until you've finished pumping your semen into her body", Charlene began to explain, with the two pups scratching their heads, not knowing what semen was. "Semen is the white sticky fluid that comes from inside a male. It's the stuff I told you about earlier that contains the sperm", I added. "Mmm...and if you put your sperm inside your sister while she has eggs in her, the sperm will likely make it to her eggs and start growing into pups of your own. However, we don't want you to do that for a while yet. Having pups is a big responsibility and it takes a lot of time and money to raise a litter", I added before Charlene continued the conversation. "Once you two are old enough to start having sex, you're free to try it as much as you'd like together if you want. However, we'll need to do a little something to keep the two of you from producing pups of your own for a while", Charlene explained. "Listen to your mother, kids. She's known females in high school that had kids long before they were old enough to handle it, and it's ended up ruining their lives", I mentioned as I felt ready to finish what I started with my sister. "Anyway, back to the lesson...there is one more part to mating that I think you two should know about", I commented as my arms released their grip on Charlene's hips while my maleness remained firmly implanted inside her vaginal canal. "You see, whenever a male fox gets...stuck inside a female like this...mmm...there's something that males do with their mates to show that they're united to them", I started to explain while beginning to dismount Charlene, preparing to turn the tie with her. "I'm sure that you two have heard the term 'tying the knot' before...well, for us it has sort of an extra meaning", Charlene continued as I turned around so that we were facing opposite directions, putting my hands and knees down on the carpet below, all while feeling Charlene's vaginal walls clamp down on my knot, keeping it in place. She also tugged on it some, coaxing even more semen from my testicles. Eddie and Ellie watched and were quite surprised when they saw Charlene and I joined together in our copulatory tie. They both seemed to be a bit confused by it. "Mom...Dad...why are you two stuck together like that?", Eddie asked curiously before his sister had something of her own to say. "Why would you two want to be facing away from each other while mating?", she commented, thinking that it was odd for a couple that loved each other to be facing opposite directions while tied. Charlene and I understood that they would have questions about it, so we did our best to explain it to them. "I know it might seem a bit odd to you two right now, but it's perfectly natural. Fox couples have been doing it like this for a very long time", I started to explain before I felt a stronger tug on my bulb by Charlene's insides. "Mmm...besides, it feels really good to be stuck to someone you love", I added. Of course, I received the majority of the pleasure from it since she would tug on my knot, though she would also benefit from having my semen slowly fill her insides. "Although it might take a little bit of time for you to get used to being tied to your partner, Ellie. Like I mentioned before, since your body is not yet used to having sex, you might feel some discomfort the first couple of times you have a male turn the tie with you. However, it will get easier the more you do it...plus, it's also the best way to ensure that you become pregnant when you're ready to have pups", Charlene mentioned to Ellie. It still seemed as if the pups were puzzled by the sight before them, but we knew that they'd eventually catch on. The desire to turn a copulatory tie during mating was a natural instinct for males, so we knew Eddie would eventually get the idea...and so would his sister. They continued to watch us remain stuck to each other with my seed slowly coating Charlene's vagina, with some of it even bubbling out of her vaginal opening, dripping onto the carpet. After several minutes, I could tell that they were starting to get bored of watching us, and a bit tired as well. It was getting close to 10 PM, which was the normal bedtime for Eddie and Ellie on a Friday Night. "Mom...Dad...how long does it take for you to be done?", Eddie commented while looking bored as his sister yawned and seemed to be drowsy. It seemed as if it were about time to finish the lesson for now. "Well, your father usually takes between 30 and 60 minutes to finish once he's turned the tie...depending on how much semen he has to give me and how excited he is to mate. However, young male foxes are usually more excited about mating and don't have as much semen to produce, so the tie may not last quite as long with them...at least at first", Charlene mentioned to the pups as I noticed how Ellie was holding her head up with her hand, her eyes looking half-open. "You two don't have to stay in here and watch us until we're finished if you don't want to. It's getting late anyway, so why don't you two go ahead and start getting ready for bed. We'll have more to discuss with you two about mating once you're old enough to do it", I suggested to the pups. With that, Eddie and Ellie were quick to get up from the bed, coming over to where Charlene and I were. They both hugged me as best as they could given my current position, then did the same for Charlene. Afterwards, the two pups scurried out of our bedroom and went to the bathroom to brush their teeth and do the other things that they normally did before bedtime. Once they were gone, Charlene and I were free to talk amongst ourselves for a little bit, as I was still pumping more of my seed into Charlene during our tie. "So, how do you think we should handle Ellie's contraception, Sis? Because you know she's going to want to mate with her brother as soon as she can", I mentioned, feeling Charlene's vaginal walls clamp and tug on my swollen bulb some more, milking another spurt of my load into her already soaked passage. It seemed as if it was going to be a messy pullout when I finished, considering that my length was also coated in a layer of my cream. Charlene thought about it for a moment and had a suggestion. "Well, we could try having tube caps placed inside her. We can even have it done before she's capable of reproducing", Charlene suggested. There were a lot more options for contraception available for females than there were back when we were young. Charlene's only option for preventing an accidental pregnancy was taking yiffberries. "That could work, but it would also mean that she'd have to get the caps replaced every 5 years...and that's assuming that the gynecologist inserts them properly and they're not defective", I answered. Uterine caps were known to be over 99% effective in preventing pregnancy, but they were not foolproof. In addition, they wore down with time, with most caps needing to be replaced after 5 years. Sometimes the caps would last even less time than this...if a female were to receive semen in her uterus regularly, or if she were to receive a very high amount of semen in her. Then, there was also my 'breeding trick', the one where I could lengthen my penis in certain forms and split it into two narrow tips (four in Sapphire's case), allowing for deep insertion. I didn't know if Eddie inherited this ability, but it was possible, and if he were to try it on Ellie, his tips could cause the caps to become loose or break altogether. "Maybe we should use the caps plus yiffberries with her. That way it's even less likely that she'll make us grandparents before she leaves home", I suggested to Charlene, wondering if she'd agree to my idea. The combination of caps plus berries would be a highly effective contraceptive measure, with near 100% success rate. However, Ellie couldn't get the berries until she was old enough to reproduce and would need to see a doctor before receiving a prescription. As I felt Charlene's vaginal walls clamp on my maleness, tugging it gently and making my seed slowly fill her already soaked passage, she gave my idea some thought and came up with an answer. "I guess we could do it that way. Though I think we should talk to Ellie about this before we have anything done. It's her body, so it should be her decision how she wants to handle this", Charlene answered. I understood what Charlene was telling me perfectly. I remembered back when we were starting to talk about sex together and how we handled things. We both agreed not to make pups until we were older, but we both wanted to feel each other naturally without a piece of latex covering my foxhood. Besides, back then flex-mesh condoms were still in the experimental phases, my knot would've easily broken through the condom once it reached full-size since Earth condoms were designed for humans, not Kapernians. We were certain that Ellie had no intention of having pups of her own for a while, so it was likely that she would agree with our idea once we discussed it with her. "We'll sit down with Ellie and talk about it in the morning. There's no real rush to get this done, but it would be a good idea to at least get the caps in before she starts ovulating...just in case", I replied as I felt Charlene give my maleness a harder squeeze, making me yip briefly as a stronger spurt of my cream left my tip. "You know, I've been thinking about what I told you earlier...about waiting to have more pups for a few years after this litter is born", Charlene mentioned as we looked at each other during our union. I was a bit surprised when Charlene mentioned this, I knew she enjoyed breeding with me, but I didn't expect her to want more pups this soon. "Charlene, are you saying that you want to get pregnant again after this?", I asked curiously while looking back at my sister, feeling her vaginal muscles grip and tug on my throbbing foxhood. Charlene blushed a little and started to coil her tails around my own. "Well, not immediately after I have this litter. I'd like to take a break for at least a few months before getting pregnant again", she started to answer while I felt Charlene's tails hug my own. "However, next year is a big milestone for us and I thought it might be nice if you and I could try to have a litter on our birthday", she added. I listened to Charlene's response and gave it a bit of thought. If she wanted to get pregnant again, I would be willing to give her more of my seed, but I also felt that we should also take a break from the breeding for a while. "Are you sure you really want to do this, Sis? We already have four pups of our own in the house and four more on the way. Do you think that you'd be able to handle having a fifth litter this soon?", I asked Charlene, trying to gauge her interest in breeding. Charlene responded by giving my bulb a hard tug, causing me to yip and making a stronger spurt of my semen launch from the tip, hitting against her cervix. "I want to have birthday babies with you! I've wanted to have them with you ever since I wanted to be my mate and I think that our 40th birthday would be a perfect time for us to have them!", Charlene exclaimed eagerly, suggesting that her mind was made up. "I know I said that we should take a break from breeding together earlier, but I really want to get this done!", she added, determined to have a litter of birthday pups. "Please? Can we at least try to have them in time for our 40th birthday? I promise that we won't have any more pups after this until Eddie and Ellie are out of the house!", Charlene begged. "You could even count it as your birthday present to me next year!", she added, trying her best to convince me to breed her for a fifth time. I thought about Charlene's comments and figured that she really wanted to have birthday babies. It made sense, considering that we shared our birthday with our mother, she wanted to do the same for at least one of our litters. "Alright Sis, if you want to try for birthday babies next year, I'll breed with you again this autumn. However, if we do this, I want you to give me a 'birthday present' from this in return", I answered. Charlene looked at me as we remained stuck to each other, seeming a bit curious to know what I was thinking about. "OK, what did you have in mind?", she asked. I blushed a little and coiled my tails a bit tighter around her own. "Well, I figured that since you would be getting a birthday litter as your present, it would only be fair for me to choose what kind of litter we have together. I promise that it won't be in our non-anthro forms, I won't make you go through being stuck as a non-anthro vixen for two months again unless you really want more non-anthro pups", I began to explain. "However, I have wondered about what kind of kids we'd produce together if we mated in some of our other forms...maybe we'd be able to produce some eevee pups together, or silver kitsune pups, or maybe even a couple of rapokids", I added, thinking about all the possibilities for future litters. Charlene listened to my suggestions and thought about it for a moment. As she did, I felt more of my sticky semen covering my shaft as it was locked inside her passage, covering every inch of my maleness, including the knot. "Well, I wouldn't mind having some eevee pups, or a couple of Raposian kids. I think that they would turn out cute!", Charlene answered cheerfully, liking the idea of having those kinds of kids. "Or, I could also show you what I showed Sapphire on our second honeymoon and we could try for some mewfox babies", I added, giving Charlene another option. Charlene saw the babies Sapphire and I made after our mating and saw how adorable the little ones were. However, I wasn't sure how interested she was in having mewfox babies of her own. "I don't know, I'm not sure if I'd want to have a mewfox form of my own", Charlene responded, knowing that if I mated with her in my mewfox form that she'd likely inherit it through the mating. I tightened my grip on her tails with my own and responded to her comment. "Alright, you don't have to have mewfox babies if you don't want to. It was just a suggestion. We'll just stick to making a litter of eevee pups or rapokids for now and we can explore our other options in the future", I mentioned to my sister calmly. "In the meantime, though, I think that I'm just about finished here. It seems like my balls are no longer churning on the inside and I think that my knot is starting to shrink", I added, sensing my climax coming to an end and my body starting to relax after our mating. The two of us finished our union after being stuck together for about 45 minutes, with me being able to pull out of Charlene once my knot was back to its normal size. Once we were free, Charlene went into the master bathroom to take a shower to wash off all the excess semen from around her crotch while I grabbed a few moist towelettes to wipe the seed from my cum-covered maleness. After this, I got my robe back on and went to Eddie and Ellie's bedroom to check on them. It was now about 10:30, so they should've been in bed by now. When I looked into their bedroom, I indeed saw the pups in bed together, with Eddie spooning behind his sister as he usually did. However, unlike some of the past times I caught them doing this, Eddie was completely naked, and Ellie was only wearing a pair of pink panties. Eddie murred happily as he held onto his twin sister, humping Ellie with his erect penis, having his tip touching against where Ellie's vaginal folds would be. I knew he wanted to mate with his sister and she likely wanted him to do it with her, especially with the soft moans I heard coming from Ellie as she slept with her brother. It seemed as if history were destined to repeat itself. However, unlike what Charlene and I experienced with our mother, Eddie and Ellie would have our full support and we would be more than willing to help them along the way. There would come a time when we would have to tell the pups the truth about the relationship Charlene and I have with each other, but that would be a subject that could wait until the pups were ready to take the next step in their relationship. To be continued (in more ways than one, see note below)... P.S.: Eddie and Ellie's story will resume in 2020 or 2021. A future story featuring Charlene and I making our 'birthday pups' will be coming in early 2020...I won't say what they will be this time around, but it's likely that they won't be in our two-tailed fox forms. *: More on this will come in a future story.
