The OTHER Talk NOTE: This story takes place in August 2020. About a year and a half has passed since my sister and I first talked to Eddie and Ellie about sex. Since that day, Charlene and I took some precautions to make sure Eddie and Ellie would be safe when they were ready to do what my sister and I have done for nearly 30 years. Ellie had uterine caps inserted in her womb about six months ago, when it was first discovered that she was starting to become capable of reproduction. It took a few more months after this, but Ellie would also receive a prescription for yiffberry candies that she could take as an added form of protection. Charlene and I kept them in our room for safe keeping, thinking that it would still be a little while before Ellie was ready to have her first sexual experience. She also started to grow larger during this time, going from 4'2" in height last year to 4'7" now, growing at the rate of about 1 inch every other month. She also began to develop breasts, though they were barely noticeable underneath her shirts. It wouldn't be too long before Charlene would need to teach Ellie about bras, though neither one of us knew exactly how large they would actually become once she was fully mature. Her twin brother was just starting to undergo changes himself, though he didn't seem as far along as Ellie. He had only grown 3 inches since we had "the talk" with them, matching his sister's current height. It seemed like in the short-term Ellie would grow faster than her brother, though in the long-term Eddie would end up being the taller of the two, though we wouldn't know by how much. Given how they were genetically similar to us, it was likely that they'd both end up around 5 1/2 feet tall (give or take a few inches) when they were full-grown foxes. More importantly, it didn't seem like Eddie was producing semen yet. He continued to dry hump his sister when they slept together, but it didn't seem like his testicles were making sperm. As for their behavior when they were together, it seemed to change a little from when we first talked to them. Eddie and Ellie still did things together, but it seemed as if Eddie was starting to become a bit more interested in Ellie romantically and probably sexually. One time, I went to go get the kids for dinner and I ended up walking in on Eddie embracing his sister from behind, licking the side of her neck while she allowed him to do so. Ellie seemed to enjoy the gentle and warm licks of her brother's tongue, suggesting that she probably felt the same way about her brother as he did for her. It reminded me a lot of how I was with Charlene when we were around that age, right before we finally got the chance to experience sex for the first time in our lives. "Do you love your sister, Eddie?", I commented in a soft and polite tone when I saw how he was treating her. Eddie immediately stopped what he was doing as he and Ellie both started blushing. "Dad! Ellie and I are trying to have some alone time!", Eddie exclaimed, feeling embarrassed about me walking in on them. As I observed the two, I noticed that there was a bit of a bulge in my son's pants, suggesting that he had an erection for his sister. "Relax...I know exactly how you two feel. I had a crush on my twin sister when I was your age", I explained calmly to the pups. "Anyway, you two can get back to what you were doing later. It's time for dinner, so why don't you go get cleaned up and meet your mother and I in the dining room", I added. For a moment, Eddie and Ellie seemed a bit puzzled. I never mentioned anything about a twin sister to them, so this was expected. "Wait...we have another aunt you never told us about?", Ellie asked curiously. "Where is she? Why haven't we seen her?", she continued before I calmed my kids down. "I'll explain everything to you after dinner, OK? For now, get your twin-tailed butts into the bathroom and wash up. Your mom and I will be waiting in the dining room", I replied in a calm but more serious tone, getting the kids to get up off their rumps and go do as I asked. Meanwhile, I went back downstairs to the dining room where Charlene and the rest of the family was gathering. My sister was busy bringing in some nice ribeye steaks that were cooked on the grill in the backyard, while Eva assisted Charlene bringing in some other grilled goodness (namely hamburgers and grilled chicken drumsticks). The burgers and chicken were intended for the kids while the adults would get to enjoy the steaks. To go along with the meat, my sisters also prepared our mother's recipe for "summer salad", along with a platter of fresh vegetables purchased from the Farmer's market down in Joplin a couple days ago. Charlene noticed me as I came into the dining room after dropping off the plate of steaks, coming over to kiss me on the side of my cheek. "Hey...did you tell Eddie and Ellie that dinner was ready?", she asked curiously. I nodded, then took hold of my twin sister's hand. "Yes, I told them...and when I saw them, they were doing something that you and I used to do together whenever Mom wasn't around", I explained to Charlene. My sister seemed a bit surprised, thinking that she knew what I was getting at. "You mean they were having sex together?", she asked curiously. "Well...not quite...although if I hadn't walked in on them who knows what they would've done. Eddie was holding onto his sister from behind and licking her", I mentioned. "Oh...OK...well, as long as they hold off on the sex until after dinner", Charlene commented, perfectly fine with letting them mate like I was, but not wanting them to do it until after they were done eating. I kept holding Charlene's hand, feeling her warmth against my own and sighed. "Sis...I think it's about time we sat down with Eddie and Ellie and told them the truth about us. I think it's only a matter of time before they actually start having sex and I think they need to know about how we used to be just like them", I added. Charlene looked at me a bit nervously, still holding my hand while doing so. "Are you sure? I mean, how do you think they'll react when they find out that their parents are actually twins?", Charlene asked, concerned about how the pups might take the news. I nuzzled Charlene softly and tried to calm her down. "I'm sure they can handle it. They're not little pups any longer, they're growing up and we need to give them the right to decide how they want to view their relationship. Personally, I think they'll end up a lot like us in the end, the only difference is that they'll have a mom and dad who doesn't try to separate them when they want to be together", I replied. I took a moment to slip a kiss in before Eddie and Ellie joined us down in the dining room. From there, we all had dinner together as a family, with Eva, Rose, Rose's eldest son (Miles), and all the kids I produced with my sisters, Rose, and Melissa (who was busy at The Oasis and couldn't join us for dinner). Later, after dinner... After eating, Charlene and I invited our oldest pups into the master bedroom to have the other important talk with them. Charlene still seemed to be a bit nervous about how they'd react, but I remained confident that they were mature enough to know the truth. We sat on one of the edges of the bed while Eddie and Ellie were sitting beside us, with Eddie on my side and Ellie on Charlene's. "So...Dad, who is our other aunt, and why haven't you told us about her until today?", Eddie curiously asked before Ellie added in. "Please tell us, Daddy. We want to meet our aunt!", Ellie added, making me feel a bit sheepish for a moment. I blushed a little, wondering if I had done the right thing by opening my big mouth. However, I soon shook it off and got up the courage to explain to the pups what I meant. "First of all, I didn't say that you two had another aunt. I mentioned that I had a twin sister", I explained to the pups. Immediately, Eddie and Ellie's ears lowered as they thought something else entirely. "You mean that our aunt is...?", Ellie started to mention while tears formed in her eyes, thinking the worst as I suddenly felt my son embrace me tightly. He also had some tears in his eyes. "WHAT? NO! She's not dead! She's very much alive!", I promptly told my pups, immediately confusing both of them. "But...if our aunt is alive, why did you tell us that we didn't have another aunt just a moment ago?", Ellie commented while she sat beside Charlene. At that point, I saw Charlene blushing while her tails coiled around each other. "That's because you don't know her as your aunt, honey. You know her as 'mom'.", I commented, also blushing some with my own tails coiling around each other, somewhat surprised that I had the courage to get it out. Eddie and Ellie sat beside us with their mouths hung open for a second or two upon hearing the revelation, then Ellie finally spoke up about the new discovery. "You and Mom are brother and sister, too?", Ellie asked in surprise. "Why didn't you tell us this before?", she added as Eddie continued to be in a state of shock. I embraced my son while Charlene embraced Ellie, us holding our pups close. "We wanted to wait for the right time to tell you the truth about us. We felt that you were too young to know that your mother and I were related. However, seeing how you and your sister have been behaving as of late, I figured it was time you knew about our relationship", I explained calmly before Charlene added to the discussion. "You see, we know exactly what you and Eddie are going through. Your father and I behaved a lot like how you two do when we were pups. That's why we decided to become mates and have you, as well as your brothers and sisters", Charlene continued as she held Ellie close to her. Eddie and Ellie seemed to become more curious as we told them more. "Mom...Dad...what was it like when you first decided to mate?", Ellie soon asked. "Because I've been having these feelings lately whenever Eddie does things with me and I'm very curious", she continued before her brother added to the conversation. "Yeah...I think about Ellie a lot, too. Every time when I think about her, I get...excited", Eddie mentioned, referring to how he was getting sexually aroused to Ellie while she was likely reacting the same way to her brother. Charlene and I kept holding the pups near us as we told them about our past. "It wasn't as easy for us as it is for you two. Your mom and I fully support any kind of relationship you and your sister want to pursue together, but your grandmother didn't feel the same way about it when we wanted to mate", I explained to Eddie. "However, that didn't stop us from doing what we wanted to do together", I continued before Charlene had something to contribute. "We don't want to spoil it for you and your brother if you two decide to have sex, but the feeling your father and I experienced when we first mated was wonderful", Charlene added while holding onto Ellie. "I remember how it felt when my inflated bulb was stuck inside your mother while she hugged it tightly and tugged on it just a little bit to make the experience even better", I mentioned, starting to feel a bit aroused as I thought about how it was when Charlene and I had sex for the first time. "Mmm...and it was even better when we finally could do it without you wearing the condom. Being joined with you was fun, but feeling your warmth spreading inside me while we were tied was heavenly!", Charlene commented back as I felt her take hold of my hand. Obviously, she seemed to get turned on to the thoughts about us mating when we were younger as well. "You two are very lucky...because we had Ellie's tubes capped and she's on yiffberries, you two can experience mating the way it was supposed to be right away", I mentioned to the pups. Eddie and Ellie remained curious as they sat with us, having more questions in mind. "Why didn't grandma want you two to be mates?", Ellie soon asked. Charlene held our daughter close and let out a sigh. "There were several reasons, honey. For starters, your grandmother seemed to be under the impression that incest is 'wrong'.", Charlene started to explain before Eddie had a question of his own. "Incest? What's that?", he asked curiously as I rubbed his back a little with one hand. "It's when two family members have a sexual relationship together...like what your mother and I do together. Of course, it's not always between brothers and sisters, sometimes it's between cousins, parents and their kids, etc.", I explained. "Generally speaking, your father and I don't have any problems with those who wish to practice incest...as long as it's consentual, but there are still some kinds of relationships that we do not endorse. We don't endorse forced incest since that is not incest based on a genuine loving relationship. That's what your father and I refer to as 'rape'.", Charlene continued. "Another reason why your grandmother didn't want us to have sex together was because she was concerned about what would happen if your mother and I inbred", I commented. "That's when two blood relatives end up making babies together", I added, attempting to head off any additional questions by the pups. "To be fair, inbreeding can be dangerous if done improperly. It can lead to serious genetic defects and other problems. That's why there are things like safe breeding scrolls available to allow couples to breed without worrying about any of these problems", Charlene added. "Fortunately, your father and I have our own protection built in, and so do you two", she added before I felt like I needed to say something. "Now Sis, let's not put too much information inside their heads. After all, we don't want Eddie and Ellie to try breeding together until they're ready to support their own family", I mentioned. Fortunately, it didn't seem like Ellie was in any hurry to become a mother. "I don't think I'm ready for that yet", Ellie commented as Charlene kissed her on the forehead and caressed her back a little. "You don't have to worry, honey. We'll do everything we can to allow you to have a normal sex life without worrying about having pups until you feel ready for them", Charlene mentioned. "We can also explain more about the protection that you and your brother have in a few more years...assuming that you two want to become mates", she added a moment later. "Of course, we'll leave that decision up to the two of you. You don't have to be mated to each other to have sex together, and you two don't necessarily have to make pups together when you're old enough for them either. Plus, we would like each of you to find at least one mate outside the family, hopefully ones that are comfortable about you two practicing incest together", I continued. We gave the pups a lot to think about with our conversation, but we would leave the ultimate decisions up to them. We felt it was better for Eddie and Ellie to decide how far they were willing to go in their relationship. Charlene and I could help them with any advice or questions that may come up, but we would do our best not to interfere with their sex lives. After we were finished talking to the pups, we let them go back to their room to do whatever they wanted while Charlene and I stayed behind. My sister snuggled in closer and held my hand tightly. "So...do you think that they're going to start having sex together?", she asked curiously. I looked to my sister, thought back to what I saw earlier from Eddie and Ellie and gave my opinion. "I don't think it's a matter of 'if' they're going to have sex...I think it's a matter of when they will start doing it", I replied before Charlene nuzzled against me lightly. "Mmm...let's have a naked cuddle together. I suddenly feel like I want to feel your warmth against me", Charlene replied as I blushed to her remark and nuzzled her back. "Alright...but no sex right now. We'll do it after the kids are asleep", I answered back just before Charlene backed away long enough to remove her shirt and bra. From there, the two of us kept taking off clothes until we were both naked, then got underneath the covers. Like I had done several times before when we were pups, I spooned behind my sister, licking her neck in a slow and loving manner, allowing my foxhood to rub against her tush. Naturally, it throbbed with excitement and leaked precum when I did this, tempting me to let it slip through my sister's vaginal opening, but I resisted the urge. We kept doing this for several minutes before we got a bit of a surprise. "Mom...Dad...can I ask you something?", we heard Ellie softly call to us, causing me to look over towards the door. "Of course, sweetheart. What do you want to...", I began to answer before I suddenly noticed that Ellie was as naked as Charlene and I were. "HOLY SHIT!!! WHERE ARE YOUR CLOTHES?!!", I exclaimed as I saw my naked 11-year-old daughter at the door to our bedroom. I did my best to cover my eyes, I did not want to see Ellie without her clothes on, mostly because I felt dirty about looking at my underage daughter without clothing. Charlene soon looked at Ellie and rubbed her eyes in disbelief. She was as surprised to see Ellie naked as much as I was. "Honey, why are you naked in our bedroom?", Charlene asked Ellie in a much calmer tone than my own. While I was still trying to look away from Ellie, she explained the reason for her visit. "Eddie and I want to mate, but we don't know how to start", Ellie explained before she looked over at me. "By the way, why is Dad hiding underneath the blanket?", she soon asked. "Nevermind that, honey", Charlene soon replied while I kept my eyes hidden from seeing Ellie's nudity. "Why don't you go back to your bedroom and wait with your brother. Dad and I will be in shortly to give you two some advice", she continued, getting Ellie to leave our room for the time-being. Once she was gone, I felt Charlene smack the back of my head. "OW! WHY'D YOU DO THAT FOR?", I exclaimed, rubbing the sore spot a bit as I looked at my sister. "For acting the way you did in front of our daughter. You know you've seen her naked before, so why are you acting like it's such a bad thing", Charlene commented. "That was back when Eddie and Ellie were toddlers, Sis...and it's not like we had a choice back then. They were too young to clean themselves, so we had to do it for them", I replied. "I would prefer to keep my thoughts about Ellie as pure as I possibly can", I continued. "Fair enough...but what if Ellie has different ideas in mind? What if she has thoughts about her father and wishes to act on those thoughts?", Charlene commented. I shook my head and growled briefly before giving my reply. "I will NOT have sex with my underage daughter!", I exclaimed. "When she turns 18, I'll think about it. However, until then I'm not going to do it, even if she pressures me to do so", I continued before I turned the question back on my sister. "Besides, would you want to have sex with Eddie at his current age?", I asked Charlene. My sister began to blush, and she looked sheepish. "Well...no...but I would think about letting him do it when he becomes an adult, at least once to see what it's like", Charlene answered back. At that point, I decided to move in closer to Charlene, kissing her on the side of her nuzzle and holding her close. "Let's not worry about that right now, Sis. Hopefully, we won't have to worry about our pups wanting to mate with one of us and be more interested in doing it with each other", I replied calmly. Charlene nuzzled me back and murred for a moment while we remained close. "Speaking of the pups, I'm sure they're waiting for us. We should probably go give them a hand", she soon commented. "Yeah, I think so", I replied before getting up from the bed and stretching briefly. Charlene also followed me, getting out of bed and stretching a little herself. Neither one of us bothered to get dressed, there was no point in really doing so since Eddie and Ellie already knew what we were like without clothes on. Besides, I was still semi-erect from the cuddling Charlene and I were doing before Ellie came in. My sister and I then left our bedroom together, hand-in-hand as we walked towards Eddie and Ellie's bedroom. A few moments later, we walked into their bedroom, seeing Eddie and Ellie together on the floor, both of them on their knees. Eddie was at about the same stage of arousal that I was at the moment while Ellie was standing next to her brother. "So...what seems to be the problem?", I asked curiously. "Well, I keep trying to get Eddie to climb on top of me like you showed us with Mom, but he's not able to put it in me", Ellie answered. "Honey, you're both new to this. You can't expect Eddie to get an erection right away. You need to do something to help him get ready", Charlene replied as she whispered in my ear. "Let's have a seat on their bed and show them what I mean", she suggested, grabbing hold of my maleness with one hand. I got the idea right away and went along with my sister, sitting down at the side of the bed they shared while they stayed on the floor. "Now then...Ellie, I want you to grab hold of Eddie's penis, just like I'm doing to your father", she continued as I felt Charlene's hand grip me just above my knot. My shaft was already starting to stiffen a little from her just touching me as my tails began to coil around each other. Curiously, Ellie did as Charlene was doing to me, grabbing her brother's semi-erect foxhood, making our son gasp a bit at the touch. "Careful Ellie, you don't want to be too rough with it. Just give it a nice and gentle squeeze", Charlene coaxed while I began to murr a little from her touching me. Soon, Eddie's maleness began to react to Ellie, slowly stiffening for his twin. "Good...now, you want to help him get nice and hard, so start rubbing your hand back and forth along him like this", Charlene soon replied, just before I felt her hand start stroking my foxhood, helping it to stiffen even faster for her. That's when I got an idea of my own. "Mmm...yes...and Eddie, while your sister is helping you get ready, you can help her out too. Just take one of your hands and place it down on your sister's crotch like this", I told our son in a soft and somewhat aroused tone, continuing to grow horny from Charlene's rubbing. After I spoke to Eddie, I moved one of my hands to Charlene's vaginal folds and began to rub them a little, making her tails coil around each other as she started to pant. Of course, Charlene was already semi-aroused from our cuddling earlier, so her pussy felt warm and a bit damp already. Curiously, Eddie followed my lead and began to touch Ellie, getting her to gasp to the touching of her sensitive vixen parts before she started to moan like Charlene was. "Mmm...good boy...now, just make sure that you give your sister a soft and gentle rub, she should start to feel warmer towards you after a little while", I instructed in a soft tone while being aroused by Charlene. "Mmm...yes...it's always better when the two of you do something together to get aroused. It feels better and it'll bring you closer to one another", Charlene mentioned as she spoke from experience, causing my foxhood to spring forth quicker, growing erect as it began to throb a bit from her touching. Both Eddie and Ellie kept following our example, with Eddie's foxhood growing stronger and more erect by the moment thanks to Ellie's rubbing. "That's it...you're both doing fine!", I coaxed, with Charlene and I watching our pups get each other horny. Soon, Eddie noticed something warm and slimy on his fingers as they brushed against his sister's outer lips. "Dad...something warm and gooey just came out of Ellie!", Eddie commented. "Mmm...that's perfectly normal, son. It just means that your sister is getting excited to have you mate with her", I replied. "Just keep rubbing against her while she does the same for you, I promise that it'll make sense once the two of you start having sex", I added as Eddie curiously followed my advice. Soon after this, Ellie began to feel her brother's length starting to twitch a bit in response to her rubbing, showing that he was getting close to full arousal. "Mom...Eddie's penis is moving on its own!", she replied while Charlene continued to massage my length with her hand while also having her pussy rubbed by my fingers. "Ahh...it's supposed to do that, honey. It means that Eddie is almost ready to mate with you", Charlene answered Ellie before she whispered something in my ear. "Speaking of 'mating'...I'm getting rather horny myself. Maybe we should do it together while Eddie and Ellie enjoy each other", she suggested to me. "Mmm...that sounds like a good idea to me", I answered back, feeling my sister's hand rubbing against my stiff maleness, causing it to twitch some more while I kept touching her pussy, now starting to dip my fingers into her warm vixen hole a little, feeling it quiver and leak. This gave me an idea for something Eddie could do to his sister. "Eddie...why don't you carefully reach for your sister's vaginal hole and put your fingers in it", I suggested to our son in a calm tone. Curiously, Eddie followed my suggestion and reached for Ellie's virgin entrance. I needed to make sure that Eddie was careful with his sister and didn't put too much pressure on her hymen. "Mmm...be gentle with her, Eddie. She's not used to having anything in there yet, so it may take her a little time to get used to it", Charlene added. Soon, Eddie's fingers found the entrance to his sister's reproductive tract and slipped inward, only pushing in a small amount. This made Ellie gasp for a second, then moan loudly from the touching, letting her walls contract a bit around Eddie's digits. At the same time, Ellie continued to massage his maleness with her hand as it had become fully erect and was now beginning to bead with precum. "Mmm...she feels so hot and moist on the inside!", Eddie commented as they kept touching each other, all while Charlene and I did the same, with my penis matching our son's in arousal, except that the precum dribbled from my own onto the floor. "I think that means that she's ready to mate...isn't that right, Ellie?", I asked our daughter curiously. "Mmm...yes...I want to mate!", Ellie replied in an aroused tone, growing more eager as the touching by her brother only helped to stimulate her even further, her pores producing even more of her sauce to lubricate her passage. "Mmm...what about you, Eddie? Are you ready to feel what it's like to mate?", Charlene replied as I kept probing her pussy with a couple of my fingers. "Uh huh!", Eddie replied excitedly, his tails starting to coil together much like ours as his maleness dribbled with precum, showing that he was about as excited as I was about sex. "Good...now, you both have seen how your mother and I mate, so I don't think I need to tell you how to go about doing it", I told the pups as Ellie removed her hand from Eddie's stiff foxhood and Eddie pulled his fingers out of his sister's vaginal passage. A few moments later, Ellie got down on all fours, just as she had seen Charlene do when we taught them about sex and placed her tails off to the side, showing off her rear-end to her twin brother. Eddie eagerly approached Ellie while we watched, with Charlene and I still touching each other, making sure to pay close attention to what they were doing. Eddie climbed on top of his sister and started to excitedly hump her with his erect penis, attempting to enter her virgin canal. "Whoa! Slow down there, Eddie! Your sister is still a virgin, she can't handle that kind of eagerness yet!", I instructed before Charlene let go of my stiff foxhood and moved from her seat next to me. She went down to where Eddie and Ellie were and came up behind our son, grabbing hold of his penis to position it at Ellie's vaginal entrance. "Ellie, let me know when you can feel your brother's tip touching your entrance", Charlene replied, helping Eddie to aim it in as she whispered something to him. "Eddie, I know you want to love your sister, but you can't be too rough with her...especially during your first time. Take it slow until she has a chance to get used to having you in her, then you can start to pick up the pace", Charlene told Eddie softly, just as his tip found its target. "Mmm...right there, Mom!", Ellie replied as Charlene backed away from Eddie, removing her hand from his maleness. "Alright, honey...we'll let you two have your fun. Just make sure that you're both careful about it", Charlene replied just as Eddie pushed forward, allowing his member to slowly slip into his virgin sister. Upon feeling him enter, Ellie felt a bit of pressure against her tight hole, especially near the entrance where the hymen was, making Ellie grit her teeth a little while we watched. "I know it's a bit difficult your first time, Ellie. However, it'll feel better soon, just as long as your brother isn't too rough with you", Charlene commented to our daughter as we both watched Eddie push inward, sending more of his foxhood into his twin sister. "Oh, and Eddie, don't knot your sister until you're about ready to cum. If you stuck your knot into her now, you'll break her hymen and cause her pain", I added. Eddie looked back to me with a confused look on his face. "Cum? What is that?", he asked as Ellie also seemed a bit puzzled. "It's a word that older males and females sometimes use to describe the semen that comes from a male's penis when he climaxes...and something that a certain someone shouldn't have used around our son and daughter!", Charlene replied, making me blush some and sweat a bit. "It slipped, OK! Besides, it's not like these two aren't going to hear that word at some point in the future anyway!", I immediately answered, feeling a bit sheepish. Charlene moved away from Eddie and Ellie now that he was in his sister but remained on the floor close by. "Anyway, just take it easy and let Ellie have a chance to get used to having you in her", Charlene told Eddie in a calm tone, just as the young male's knot touched his sister's outer lips. "By the way, how does it feel to have sex together so far?", Charlene asked a moment later as I stayed on the bed, feeling my maleness twitch a bit as it remained hard. Eddie began to hump Ellie, moving at a modest pace, feeling the tightness of her virgin vixen hole around his throbbing member. "Mmm...she feels so warm and squishy inside...and she's hugging my penis really tight!", Eddie mentioned in an excited tone while Charlene and I watched. Meanwhile, Ellie felt the spurts of her brother's precum entering her body, hitting against her cervix while the rest of his maleness rubbed against her insides. "Mmmnnhhh...he feels so hard...and I can feel his stuff getting inside me!", Ellie added a few moments later. "That's just precum, honey...when it comes out, it means that you're making your brother feel good", Charlene mentioned to our pups as I couldn't help but grinning to my sister's comment. "So...what was all this about me not using a certain C-word in front of our pups?", I asked Charlene sarcastically. She immediately turned towards me and sighed. "Alright...now we're even! Now, are you going to come down here and join me or not?", Charlene answered in an annoyed tone, catching me a bit by surprise when she mentioned she was waiting for me to join her. "Wait...are you saying that you want me to mate with you?", I asked from the bed, watching as Charlene suddenly got on all fours and presented herself to me. "What do you think?", she replied in a sarcastic tone, her tails drooped off to one side as I saw how moist her pussy looked. "Jeez, Sis...calm down! All you had to do was ask!", I replied, quickly getting down from the bed and going over to Charlene. It didn't take me long to place my foxhood inside her, holding her hips with my hands and beginning to hump her while Eddie and Ellie were going at it just a few feet away from us. "Mmm...that's more like it!", Charlene replied, enjoying my maleness rubbing against her hot vixen folds, all while I felt her squeeze and massage my member as it passed through her, my knot kissing against her outer lips with each inward thrust. While I mated with Charlene, I looked over at my son, watching him humping Ellie as she started to pant, enjoying the feeling of her brother's foxhood rubbing against her insides a bit more. "Do you love your sister, Eddie?", I asked in a sweet tone, getting him to look back at me. "Uh huh!", he quickly replied, continuing to deliver his throbbing length to Ellie's tight and dampening vixen hole, feeling her squeeze back on his member a bit as she got used to having him inside of her passage. "Well then, let me show you something else you can do with her while you two have sex", I replied before reaching for Charlene's neck with my tongue, licking it in slow upward motions. As I did this, Charlene's pussy spasmed around me, tightening her grip while also releasing more of her love sauce to make it easier for me to hump her. Eddie watched me and soon followed my example, doing the same thing to Ellie. This made her respond to him the same way Charlene was to me. "Mmm...I love you too, Eddie!", Ellie soon replied, feeling her excited twin hump her more vigorously, letting his knot press against her outer lips some more. I could see that the pups were getting into having sex together more. Ellie seemed to enjoy her brother's length probing her more while Eddie seemed to enjoy the tightness of his sister's passage, beginning to shift his weight a bit from side-to-side while humping her. I was doing the same with Charlene as my own knot pressed against her vaginal lips, attempting to slip inside her warm canal before I injected another batch of sperm into her. Charlene started to lean back towards me a little, allowing her folds to press against my bulb a bit more while turning her attention towards Ellie. "Mmm...Ellie, honey...does it feel like he's trying to put his bulb inside you?", Charlene asked while I was busy enjoying her tightness. Ellie looked over towards her mother before replying. "Ahhh...yes...I think so", Ellie answered before mentioning something else. "Ohhh...and it feels like it's pulsing against me when it touches!", Ellie added a moment later. Charlene knew exactly what was going on. "Honey...let him inside you. I think your brother is ready to put his seed in your belly", Charlene replied as my own bulb started to pass through her entrance while I felt her vagina clamp down firmly around the rest of my member. "Ahh...speaking of which, I think it's about time I gave you a cream filling of my own!", I replied to Charlene, getting my sister to giggle briefly. "Mmm...go for it!", she replied happily, ready and willing to take my knot and my load. I pushed my knot forward, letting it slip through Charlene's entrance and become surrounded in her warmth, all while she did her best to grip it tightly. Before I came inside her, Charlene managed to give Ellie some last-second advice. "Ahh...push back towards him some, it'll help his knot...get...inside...", Charlene explained to Ellie just before I moaned with delight and came inside her, sending a thick gush of my kitsune seed splashing far into her canal, all while my knot grew larger near her entrance. As I came, Charlene called out excitedly, feeling my hot and sticky load hit her vagina, cervix, and uterus. "Ohhh...it feels so good when you feel it get inside you, Ellie. You can feel its warmth spreading throughout your insides, making them tingle all over", Charlene mentioned after she calmed down a bit, attempting to coax Ellie into letting her brother knot and cum inside her. Curiously, Ellie did as Charlene suggested, leaning back towards Eddie a bit as our son eagerly humped his twin sister. The young male fox panted excitedly as he felt his seed churning within his balls while the rest of his maleness throbbed with approval. He loved how tight and moist Ellie felt around his member, constantly pressing his knot against her with each inward thrust. Finally, Eddie succeeded in knotting Ellie, making the young vixen gasp briefly before Eddie let out a playful growl, reaching his climax. A stream of the young male's sperm began to flood into Ellie, splashing against her cervix and uterus while she tightly held his maleness and knot, feeling it grow larger. "Ahh...it's so warm and sticky!", Ellie called out, responding to the feeling of her brother's seed against her insides, all while the young vixen seemed to get into mating a lot more. Her folds erupted with a torrent of vaginal sauces, soaking Eddie's foxhood and coaxing the knot to grow bigger. Charlene looked over at our pups while I was busy filling her, my knot nearly full-size as the flow of seed began to slow some. "Mmm...now you two know how your father and I feel", Charlene mentioned in a soft tone. "It's not over yet. There's still something else your brother can do for you, honey", I added, just as my knot reached full-size and the flow of cum into Charlene slowed to periodic spurts. I showed Ellie what I meant by dismounting Charlene and turning the tie with her, having my bulb being tugged on by her tight vixen folds, slowly milking more seed from my balls. "Mmm...yes...you two should give this a try. It feels really nice to be tied to your brother while he slowly fills you", Charlene coaxed, just as Eddie's bulb reached its full size inside Ellie. "Mmm...just take it slow, Eddie...don't turn the tie with your sister too quickly your first time", I added while my sister's vaginal walls clamped down tightly around my pulsing knot and I felt spurts of my semen leaving me, adding to the pool of cum that formed when I came inside her initially. Eddie followed my advice and dismounted Ellie, slowly turning around until they were facing opposite directions, still having their genitals locked together. Ellie gasped a bit as she felt Eddie turning the tie, feeling his bulb tugging back a bit as her inexperienced body tried its best to adapt to the new experience. However, her vixen instincts soon started to kick in a little more, with her body grabbing hold of his bulb tighter, responding to the pulsing she felt in it and the rest of his maleness. Meanwhile, Eddie moaned in delight over how he felt, liking the way his maleness was being hugged and squeezed by Ellie, all while he kept pumping in more of his sperm. While I was joined with Charlene, I looked over to my son (who was next to me just a couple feet away) and had a little father/son time with him while spurting more of my cream into his mother's womb. "So, how does it feel to mate with your sister? Pretty good, right?", I asked in a calm tone, getting Eddie to look over at me. "Ahh...yeah...it feels really good! Thanks for showing us how to mate together, Dad!", Eddie replied in a happy tone, just as I noticed that Eddie and his sister were beginning to coil their tails around each other, just like how I had done to Charlene at times when we were tied. "How are you holding up, honey? Do you feel a large puddle of your brother's seed filling your womb?", Charlene asked Ellie soon after I spoke to Eddie, the two females next to each other in the same way Eddie and I were. "Ahh...yes...and it's still getting bigger! I can feel Eddie putting more of his stuff inside me!", Ellie replied before another thought entered the young vixen's head. "Mom...how long are we going to be stuck like this for?", Ellie soon asked. Charlene kept her grip on my member tight, tugging on it some more as my seed kept entering her uterus, making the pool of cum grow larger, spreading to areas that had not yet received it. "It depends on a lot of stuff honey...like how excited your brother is to mate, how well the two of you are stuck to each other, how much fresh seed he has to give you, and a lot of other things". "Usually the tie lasts about a half-hour, honey. Although, when your mom and I do this together we're usually stuck like this for longer than that. I don't think Eddie is old enough to produce as much sperm as I can for your mother, so your tie probably won't last as long as ours...at least not right now...but as he gets older and is able to make more sperm, he should be able to stay stuck with you longer", I added. "Mmm...just relax and enjoy the feeling, Ellie. Try to give your brother's bulb a tug every now and then, it'll help him put more of his cream inside you", Charlene mentioned just as she did what she told Ellie to me, making me gasp for a moment before I felt a stronger spurt of my seed launch into her. I expected Eddie and Ellie to finish their tie before Charlene and I finished ours, I didn't think Eddie would be able to last as long in his sister as I could with their mother. However, Eddie surprised me, staying joined to his sister for as long as I was with Charlene. In fact, I pulled my shaft out of Charlene just before Eddie pulled his out of Ellie, though it seemed as if we both finished inseminating our partners at about the same time. Following the dual matings, mother and daughter were still on all fours, basking in the warmth that we provided for them. Both Ellie and Charlene had seed dribbling from their vaginal openings, with more of it oozing from Charlene's than Ellie's. Even though Eddie and I were joined to our siblings for about the same amount of time, it still appeared that he had some growing to do before he could inseminate Ellie as much as I did to their mother. "Mmm...so...how does it feel, sweetheart? Did you enjoy mating with your brother?", Charlene commented to Ellie while Eddie and I made our way to the bed, sitting on the edge of it. "I love it, Mom! I want to have Eddie mate with me again!", Ellie replied eagerly as it seemed the young vixen wanted to go another round sooner rather than later. Charlene giggled to Ellie's reply and finally got back up to her knees. "Mmm...not right now, honey. It's getting close to your bedtime and I think you and your brother should get cleaned up", Charlene replied before helping Ellie back up to her feet. "Yeah, and Eddie also needs a little bit of time to rest. I'm sure he wants to do it as much as you do, but he can only do so much at one time", I added. "In the meantime, why don't you and your brother go get in the shower together and get ready for bed. Mom and I will come back in a little while to check on you", I continued as Eddie and Ellie did as they were told, heading off to one of the bathrooms to get clean. Meanwhile, Charlene and I went back to our bedroom, heading for the master bathroom located inside of it to shower ourselves. As we showered, I felt Charlene from behind me, gently rubbing my crotch with body wash to get off the leftover vaginal sauce and cum. "So...what do you think? Are Eddie and Ellie going to end up like us?", Charlene asked curiously as I felt the body poof rub gently against my sheath. "I don't think it's a matter of "if", Sis...I think it's a matter of "when". As in, when are they going to get the urge to make pups together like we did", I replied. "They seemed quite happy together, and it's obvious that they love each other, so I think it's only a matter of time before they decide to give us grandpups", I added. "Yeah...I see what you mean. I just hope that they're not too eager to breed together. I'm too young to become a grandmother", Charlene replied with a chuckle. "They're good pups, Sis...I'm sure that they'll wait a while before trying to create a family of their own...at least as long as we make sure that Ellie is using contraception", I answered back. "I know Eddie is not going to want to wear a flex-mesh condom over his penis, not after he and Ellie had raw sex together", I added. I felt Charlene finish washing my crotch before she nuzzled against my cheek a little. "Yeah...and I'm sure Ellie wouldn't want him to wear one either", Charlene replied. I murred softly, then nuzzled Charlene back, the two of us finishing our shower before getting out and drying off in the turbo dryer chamber. After several more minutes of getting our hair and our fur smoothed out, Charlene and I put on our personalized robes and made our way back to Eddie and Ellie's bedroom. When we got there, the twins were already in bed, still completely naked from what we could tell while facing each other. They were locked together in a deep kiss, with Eddie and Ellie sharing saliva while I noticed that he was humping against her. "Let's give them some time to themselves", I whispered quietly to Charlene, thinking that it wouldn't be right to disturb the twins while they were being intimate. Slowly, I closed the door, doing my best not to be noticed. "Goodnight, you two...have a good time together", I added softly before Charlene and I left them to make out together before we went back to our room to unwind a bit. To be continued...but not until Eddie and Ellie are a bit older.
