Breeding Season As I lay in bed by myself early one morning, completely naked with the lower half of my body covered by a blanket, I reached over for the side of the bed where Charlene was laying next to me the previous night. Although we did not have sex together the previous night, I was aware that Charlene was in a breeding mood once again and wanted to have my sperm fertilize her eggs like we had done before. She was simply waiting for our mating season to begin where her body would be at peak fertility before she let me fill her again, which is why she was resting at my side. We never knew when our annual sexual peaks would hit exactly as it tended to vary from year-to-year. However, we did have a rough idea of when it usually happened, based on past experience as well as what was normal for foxes. Typically, our annual sexual peaks began somewhere between our birthday and Valentine's Day and lasted around a month for Charlene and about two months for me. I knew I hadn't reached my peak yet as my foxhood would become deep red, more sensitive than usual, and drip with precum even if it wasn't fully erect. Typically, Charlene and I entered our annual sexual peaks together, but there have been times where she's reached hers before I've reached mine. However, I knew that it would happen eventually and as soon as Charlene was in the mood for more pups, I was more than ready to give them to her. In the meantime though, I tried to reach out to Charlene, thinking she was at my side still on the bed, only to find an empty space there as I opened my eyes a little bit. "That's odd...I wonder where she could've gone. It's not like her to get out of bed whenever we sleep together before I wake up", I thought curiously while I slowly woke up from my sleep and looked over at the nearby alarm clock. It was 7 AM and the skies outside were still somewhat dark as it was late January, meaning the sun didn't come up until around 7:45 or so. Because it was still somewhat dark outside and Charlene was in bed, I figured that maybe she had just gone into the bathroom or something and would be coming back to bed soon. So, I decided I'd just try and wait for her a little bit and closed my eyes once more. Not more than a few seconds after I closed my eyes, I felt two warm paw pads touch my shoulder and a warm tongue licking at my cheek in a rapid and playful manner. At first, I thought it was Hope, but the paws felt a little bit smaller than hers as the licking continued, also accompanied by a soft murr. Curiously, I turned over and opened my eyes just before I got a faceful of vixen tongue and felt all four paw pads touching my body. As my eyes opened, I got a good look at who was licking me and I soon found out the reason why Charlene wasn't resting by my side. "Well, hello there...I didn't expect to find you like this", I commented to Charlene as she had changed into her non-anthro form and moved closer to me to rub her nuzzle against my own. I placed a hand on her back and softly caressed her vixen fur while I felt her nuzzle against me while murring softly with both of her tails moving from side-to-side a bit. "So, what's the deal sis? Why did you decide to change into your non-anthro form?", I asked her curiously, knowing she could understand what I told her and also knowing that I could understand whatever she told me*. Charlene didn't have to say a thing to me though as I watched her turn around and present her rear to my face. I watched her raise her tails high and move her rear-end back towards my face as my eyes saw the reason why Charlene had changed. "Oh...I think I get it now", I answered while looking at her vulva and feeling my shaft starting to unsheath at the sight of it. Charlene's vulva had become dark and swollen, looking a lot like that of any other non-anthro vixen during mating season as it signalled that she was ready to breed. This must've been Charlene's way of telling me that she was ready for pups now and that she wanted me to have sex with her as I sat up on the bed and stretched for a moment. "Alright then, if it's pups you want, I'll be more than happy to breed you", I told my sister softly while yawning and stretching. "Just go ahead and change back to normal and we'll have some breakfast before we do it", I added as Charlene looked at me with her blue eyes and yipped at me. "What do you mean you don't want to change back right now?", I asked curiously. Charlene continued to yip and bark at me which to human ears would sound like standard fox noises, but to mine sounded as clear as if she were speaking English. "Oh, so you're telling me that you want to have some non-anthro pups with me this time", I answered before I felt her leap up onto me and lick my face while she stood on her hind legs in front of me. "Alright...if you want to do it that way, we'll give it a try. But I think we should still eat something first before we breed", I told Charlene before I picked her up in my arms and carried her towards the kitchen. When we got to the kitchen, I placed her down on the floor while I went to the cupboard for a couple bowls and cereal. I figured that since Charlene seemed to be in the mood to mate as soon as possible that I'd make something quick for both of us. I usually bought the cereal that comes in the bags rather than in the boxes since it was usually cheaper and there was more to a bag than the box. Besides, more or less, it's the same thing whether it came in a bag or a box anyway. Furthermore, when it came to cereal, Charlene and I both had a "never wanna grow up" attitude towards it. We preferred to get the stuff that we liked having as pups and leave the boring adult cereals for other people. Charlene and I each had our own personal favorites, but we would usually eat whatever was available to us. We didn't have any of the generic version of "Froot Loops" that she liked on hand, but we did have my cereal available. I poured some of that for both of us, knowing Charlene would eat it anyway as I figured I'd have to go out sometime in the near future and get her a bag of her cereal. I poured the cereal and the milk, giving one bowl of it to Charlene, serving it to her on the floor. There was no need for a spoon for her, she'd simply lap it up directly from the bowl. Meanwhile, I took my bowl of cereal and a spoon to go along with it to sit at the table and eat. While I was having breakfast, I periodically looked down at Charlene as she was lapping up the cereal and milk with her tongue while I saw her rear-end facing towards me. Her vulva was twitching a bit as her two tails were raised high, which caused my erection to continue growing. I started to have the urge to give her a few licks with my tongue, but I had to fight it off for now until we were done with breakfast. However, it was difficult to resist the urge with Charlene unintentionally presenting towards me like that and with my foxhood beginning to throb excitedly for her. I did manage to keep my sex drive in check until I was finished eating as Charlene had finished around the same time as well. By the time I was done with breakfast, my foxhood was fully erect and Charlene immediately noticed it when I turned around to pick up her bowl. She licked my face quickly with her tongue and turned back around to present herself to me again (deliberately this time), having her tails and rump raised high. "Just give me a couple more minutes, sis. Why don't you go into the living room and wait for me while I take care of everything in here", I suggested to my sister. She let out a yip and soon left for the living room as I put the bowls in the sink and put everything else back where I got it. The time I spent doing this caused my foxhood to cool off a little bit, but I knew that once I got back together with Charlene, I'd quickly warm back up for her. Finally, once everything was put away and the kitchen looked the way it did before breakfast, I figured it was time to give Charlene what she wanted. I closed my eyes and concentrated for a few moments, thinking about my non-anthro fox form as I shrunk down to non-anthro fox size and changed into that shape. The transformation only took a few seconds and by the time it was done, I was on my four paws as my nose could sense Charlene's eagerness to breed, causing my fox cock to grow aroused once again as I followed my nose into the living room. When I walked into the living room, it didn't take long for me to find Charlene. She was standing in an open portion of the living room, finding a spot that had plenty of space for us to mate in the natural vulpine way. The sweet and arousing scent of her heat drew me closer to her while my foxhood throbbed underneath my belly, continuing to act aroused as I approached Charlene. When she noticed that I was close to her, I watched as she turned around with her rump facing towards me again, her tails raised high, displaying how swollen and excited her vixen vulva was. I could see a little bit of her juices trickle out of her opening while watching the entire vulva move up and down a little bit, showing that Charlene was definitely ready to breed. I came closer to my sister, moving slowly while the scent of her heat intensified and kept my shaft unsheathed and aroused. Because I didn't do it while we were having breakfast, I decided to reach my tongue out towards her vulva once I was close enough to her and lick at it a few times. I felt the warmth of her juices touch my tongue, causing my two tails to coil around each other while my foxhood began dripping with precum. Her juices tasted like they always did, sweet and tangy with a burst of warmth that ran down the length of my tongue and worked through my entire body. This caused me to let out an excited murr while I felt my length pulsating and dripping precum onto the carpet below. I was ready to mount Charlene and she knew it as I soon saw her two tails drop to one side while she had her rump raised high for me. Without wasting any time, I pounced onto her back, latching my front legs around her hips and pulling my body over the top of her back. At the same time, I brought my lower body towards Charlene's rear-end with my erect foxhood beginning to hump against her backside. I could feel the tip of my shaft touching her from behind, hitting against the area around her vulva as I tried to find the sweet spot. It took me a few times to get my tip pointed at the right angle so where it touched her vaginal opening, but as soon as I felt it, I pushed my shaft inward, sending it into Charlene's reproductive tract. Upon entering Charlene, my front legs tightened a bit while I began to move back and forth inside her at a moderate pace, soon having all of my foxhood except the knot inside her vaginal passage. She felt just as I expected her to feel within...hot, wet, and slowly growing tighter around me while I felt subtle movements of her vaginal walls around my foxhood. This made it feel very good for me while I was in Charlene as I humped her foxy-style with my two tails raising high from my sexual delight, feeling the massage of my sister's body stimulate my cock. A few moments later, I began to feel Charlene leaning back towards me, pushing her swollen vulva lips against my knot while the rest of my shaft continued to move back and forth through her tight vagina. I felt her juices begin to trickle onto the knot as I humped her, slowly increasing my speed while I remained over Charlene, murring happily while I felt my foxhood throb and spit precum deep into her fertile vixen womb. I always loved having sex with Charlene, it strengthened the bond that we always had for each other ever since we were in our mom's womb. The sex was even better for me whenever Charlene decided that she wanted to give me the ultimate form of her love by allowing me to make pups with her. This made my balls feel quite active as they dangled underneath me, not only were they swollen from me saving up my load for a little while, but they were also reacting to my love for my sister. I could feel just about every sperm-filled inch of tubing inside my nuts churning, trying to make the load I would soon inject into her as potent as possible. However, I also figured that they wouldn't be completely drained after one climax and Charlene probably would want more sex afterwards. For now though, I tried to concentrate on the job before me, continuing to plow my horny foxhood through Charlene's tight and spasming vagina, feeling her walls massage me from all sides as she became extremely warm and wet within. My front legs clutched her hips even tighter while I began to move from side-to-side as I humped Charlene, attempting to get my knot inside her hot vixen folds. I could tell she wanted the knot since she kept pushing back towards me while the entrance to her vagina spasmed tightly around my foxhood. I could also feel the spurts of my precum becoming more frequent, reaching further into Charlene while my shaft became more sensitive to touch. We soon started to pant heavily together, both of us happily engaged in brother/sister sex, enjoying the feel of each other's reproductive parts as we both worked to create new life within Charlene's receptive body. My desire to cum inside my sister grew with each passing moment as I felt my knot hit up against her vulva repeatedly. It was getting closer to going inside her, pushing up against the opening for a moment before I pulled back a bit just to have it hit up against it a moment later. I leaned over her some more, reaching the back of her neck with my nuzzle while I continued to pant excitedly. I wanted to lick her neck lovingly, but I held off on this urge for now, preferring to wait until I began to inseminate her before I did. After a few more moments, I felt Charlene's opening seem to widen around the knot, swallowing my bulb into her hot vixen folds right before she started to clamp down hard on it. Once my knot was inside her, I felt it rapidly grow inside, pushing back against her walls as she grabbed it from all sides. This is when I moved very quickly inside her, giving inward thrusts while rocking my body from side-to-side, trying to make absolutely certain that we would be stuck together when I filled her womb. At the same time, the pressure in my swollen balls was nearing its peak as they could sense the growing tightness of Charlene's walls around my foxhood and knew that it was just about time to deliver my contribution to our litter to Charlene. I heard Charlene continue to pant while I moved from side-to-side, feeling the sensitive tip of my shaft and my knot being rubbed vigorously all over, trying to coax my seed out of my balls. The jets of precum into her passage had stopped while my length became very thick inside her canal, pushing against her walls while I also felt her clamping down tightly on my growing knot. Her heat radiated around my entire length, bathing it in her juices while I felt a few subtle spasms of her walls against me. I knew from the way she felt around me that I couldn't hold my reproductive urges back any longer. With my knot reaching its full-size and becoming locked inside Charlene, I began to shoot my load into her. My sperm gushed out of the tip of my foxhood and splattered deep into Charlene, hitting her cervix and seeping into her uterus as it came out in a powerful and steady torrent. She let out an excited yip when I began to fill her while I murred happily and began to use my warm fox tongue on the back of her neck, showing Charlene exactly how much I loved her. She turned her head towards me while I was on top of her, licking me on my nose with her tongue while we became stuck together and began to make our pups. I murred happily to her sweet kiss and returned the favor by licking her pink nose before the tips of our tongues met. I felt the warmth of Charlene's tongue on my own, briefly strengthening my orgasm while also causing Charlene to spasm a bit tighter around the knot, as we both knew how lucky we were to have each other in our lives. During the initial part of my climax, I remained still inside Charlene, feeling the heat and tightness of her vaginal walls cause my shaft to shoot my seed deep within her tract at an intense pace. I was certain that most of my load was making it through her cervix and into her uterus, giving Charlene a powerful dose of my sperm to fertilize all of the eggs her ovaries had released. However, our mating session was far from over. After about a minute of my intense spurts of fox cum, my shaft settled into its normal pattern of delivering short, periodic spurts of seed into Charlene. This was my cue to dismount my sister and complete our bond. My front legs released their grip from Charlene's hips while her vaginal walls clamped down hard on my knot, keeping it and the rest of my shaft inside her during this time. Gradually, I climbed off her back and turned around slowly in the opposite direction while feeling Charlene's walls tugging back on my length a bit to hold it in place and to milk more sperm from my balls. There was no need to rush with this, we both knew we wanted to be tied to each other and each moment that we were bonded together helped to strengthen the love that we had as siblings and as mates. Eventually, I completed the turn, now facing the opposite direction from Charlene while feeling her continue to tug on my length with her vaginal walls, allowing more of my sperm to shoot into her fertile body. Once we were tied, I looked back at Charlene, seeing how we were stuck together as her two tails were raised high along with her rump while she lay low to the ground. Then, Charlene looked back at me, placing her tails up against my own as they coiled around each other during our bond as she yipped in a high-pitched tone. In fox language, she was telling me that she loved me and I yipped back to her, telling my sister how much I loved her. Meanwhile, we remained stuck to each other, my knot firmly in place in her vagina while the slow insemination continued. I felt the heat of her vaginal walls ripple around my foxhood during this time, making me feel warm all over as I felt both happy and proud to be inseminating my cute sister. She seemed to take just about every drop of my cream that I put into her, making sure to remain in her current position during our tie and allowing as much of my sperm to reach her uterus as she possibly could. With that being said though, I was certain that one mating wouldn't satisfy Charlene's urge to breed. It might temporarily satisfy her maternal urge, but I was sure she'd lift her tails and rump for me again not long after I pulled out of her and want another dose of my seed. In the current state that I was in, I'd give Charlene as much as she wanted, breeding with her until she was certain that our pups were implanted in her uterus and beginning to grow inside. The tie between Charlene and I lasted about a half-hour, with my balls slowly releasing cum into her reproductive tract while her walls helped to milk it out of me. However, as the tie continued, my sex drive slowly began to die down as the feeling of sexual satisfaction began to come over me. I had planted a strong dose of my sperm into Charlene and my balls were feeling happy about it, which caused my knot to begin shrinking. Even with this occuring though, the grip on my knot remained tight for a few more minutes, gradually loosening as I began to pull away from Charlene after a while. The flow of my sperm came to a stop inside her, saving what was inside my balls for future matings as I slowly felt my bulb coming out of Charlene's tight grip. I didn't think Charlene wanted to let me go, but she knew that there wasn't any choice. We couldn't stay stuck to each other forever and I would need a little bit of recovery time before I could be aroused to mount her again. Eventually, my knot popped free of her vulva, followed quickly by the rest of my shaft as a small trail of leftover cum briefly connected between her opening and the tip of my foxhood. Upon leaving Charlene's vagina, my foxhood hung down for a few moments, dripping with leftover cum while I turned around to face Charlene once again. She quickly got down on the floor and reached down towards her cum-covered vulva lips with her tongue, licking it clean and enjoying the taste of my seed mixed together with a bit of her juices. Then, Charlene came over to me, licking my semi-erect foxhood with her tongue as the sample from her vulva lips didn't seem to be enough for her. Of course, her licking did tickle my length, but it did little for my sexual appetite at that moment. I was still basking in the afterglow of mating and it would likely take about an hour before I could be aroused to mount her a second time. In the meantime though, I let Charlene lick me clean before she started to lick my face while we walked together side-by-side, acting much like a happily mated feral fox couple as our tails were hoisted high. In a little while, I knew Charlene would dart out in front of my again, flag her tails and raise her rump, showing she was ready for a second helping. But for now, it was a time for us to rest a bit. To be continued...
