Incest is best, right? Or, the story of 'That Time I Came on My Sister's Chest'. It was the beginning of summer, our parents were busy. Fishing tours were all day affairs and during break, we rarely saw them. Which was fine for us. She's afraid of water, I wanted to bike more. Which that summer, was literally my downfall. We were set to start highschool after the summer break. Which was the break I broke my wrist on one hand, two fingers on the other. The break where my brake's broke, breaking... Sorry, stupid. It was looking to be the longest month in my life. Or at least, it might have been if not for Mandy. Sandy-Mandy to Dad, Manda to Mom'n me. It started out as you may have expected. Manda wanted to do her own thing, not be stuck at home with my broken-ass. Which had survived the fall, thank you Cat-God. We lived a little rural-y, friends that visited tended to stay for a whole week out of convenience. No one wants to spend an hour both ways just for a couple hours. I may be a little ramble-y right now, sorry. I know I teased the 'good' part early on. But, it's not easy putting those thoughts down for someone. But, hey. We've gone that far already, right? Since neither of us wanted to work that summer, we were supposed to look after eachother and the house. Well, that fell through as hard as I did and now it was a rather uneven 90-10 split. The only thing she didn't do for me was wipe my arse... But, that didn't stop us later on. The first week I spent with her and her two friends Leslie and Jess... Which goes no where you may have been imagining. I got to control the TV since it was all I actually could control. So, we spent that entire week hanging out watching movies on the couch. But, Manda always sat beside me and it was the last bit of 'normal' we had going forward. In particular were two nights where our parent's were gone over night. We got permission to order food from the diner up the highway and those two nights were spent up late enough for the more 'Feral' of movies to come on. Fur, soft music, alluring angles... Steamy scenes all around. Stuff our Parent's definitely wouldn't have wanted us watching. But, we were alone, we were curious and by the end of that week things were getting difficult. Manda and I weren't twins. But, we were born within a year of eachother. Fall-baby, summer baby. She had Dad's thick fur and cheek ruffs, crooked ear big smile. I had Mom's longer fur, soft and fluffy 'round the middle especially. Not that the extra fluff helped, I was still stuck on the couch those nights being fed burger-on-a-fork and fries-at-a-time. Leslie and Jess had wandered off to bed not long before that first movie. Why Manda stayed is beyond me. Maybe it was the fact that we had both been unable to fully hide our aside-glances. We were after all the only ones outside of Mom'n Dad we saw regularly outside of school. While they were affectionate and given both Manda and I having interrupted things... They were active. Though, we never did wind up with a third sibling. The 'movie' in question was definitely an excuse to string together steamy scene after steamy scene. Six friends, one beach house, and a plot so strung together, it was a miracle the plotholes weren't seduced. "Ya' think we should change it?" Manda asked, her tawny eyes flicking from detail-to-detail as they caught her attention. "Uh... yeh." I agreed reluctantly, a little hot'n husky from it already. I had tried to tend to things on my own... Didn't work. Trying to close the fingers I had left in a way that worked only ended in frustration. I didn't try it. But, the cast would have surely only lead to pain. Poking at the remote did nothing. Thwacking it against my leg did nothing. Swapping both batteries around... Nothing. At that point it was no longer a softcore fur-fest. It was as hardcore as they could get away with. They didn't zoom in... But you knew and saw where everything was happening. "Hey Mandy... Could you get up and change it for me? I can't... Y'know." it was tight. The pillow I was resting my wrist on was now a modesty pillow. I couldn't bring myself to look at her and I could only look away so much. Mom'n Dad were fairly strict about watching that kind of thing. My talk consisted of Dad telling me that whatever I found should be tucked away and not hidden and to lock the door when I 'needed privacy'. It never occured to them that Manda and I would come so close... So to speak. Maybe it was needing to care for me. Dad took care to help me in the shower, Mom was a nurse previously and the first couple nights after being done up... Well, thankfully I could do that after I was done on my own again. But, her helping me eat, drink, move around had brought us perilously close together. We were young, we were hormonal, and now we were both horny. "Ya, lemme just... Hupf." and she was up. Her bobbed tail dancing from side to side as she swiftly tip-toed to the TV and after lingering noticeably... Changed the channel to just Music and flicked the set off, leaving us in the dim light from the kitchen. "So... Did you need a minute to... Y'know?" she asked. I was still going to need some help getting up, after a disastrous first attempt and a stern telling off from Mom about letting people help me. I tucked tail'n ear folded my way into letting people treat me like a delicate vase. It would go down. It had to go down. I did my best 'there's a classroom emergency' hoping it would go down. It did not. It was late, Manda probably wanted to 'lock her door for privacy' as much as I did by that point. The muffled buzz of her toothbrush was something I had picked up on as strange. Especially given we shared a bathroom on our side of the house. "N-not out here. Dad would kill me if I did That." Catgod knows I wanted to, sneaking my way in here to catch a quick five-ten minute scan for Those types of movies. "Mandy, could you help me up now? It's dark enough so..." I reasoned. Forgetting the fact that the bunched of shorts I was wearing would do absolutely nothing to hide the problem. Spoiler alert, it didn't. The flush that was on her face was something I'll never forget. That moment where everything changed. The modesty pillow was put off to the side, Manda had far less of an excited return. I could tell she was as nervous as I was and with one modesty arm, then the other lifted away. A shared 'Hupf!', a pained wince from me and I was standing, and standing erect. The loose fabric betraying me in the worst possible way as my unrestrained Thing pressed up and into her navel. There was no mistaking that. "Sorry! Sorry, I'm so sorry Mandy. I didn't mean to!" Disregarding the pain from both arms in lieu of the elephant in between us. "Lets... go to bed. Er, to our own beds. In our rooms." she instructed, clarified, and elaborated again. It was an awkward shuffle as I untangled from her beside the couch. My Thing bumping against her as though it had a mind of its own. She was so warm. I had no idea then I'd find out just how much later that month. She followed behind me a respectful second or two later. By then I had rounded the hallway corner and was quickly striding towards my room. Escaping the awkward situation. A situation we both knew shouldn't be happening. Yet, an inexorable desire to see more of it. I gently shut the door behind me, Manda's soft footsteps wandering further on, the soft click of her door in the quiet house. One last door, the walk-through shared bathroom. We both had the same thought, my longer fumbling at the 'lock for privacy' wound up with her face to face with me in the full light of the bathroom. Something we kept on as a closed door meant Occupied. "Did you want the bathroom first?" I asked. She nodded, eyes flicking down. I covered up, a sheepish smile and understanding nod before slowly clicking the door into place. Her door creaked open, a few moments later, it closed and the shower started running. I knew what was happening. The shower water wasn't being moved around for a time. It wasn't all that long. I had my own struggles. I knew if I kept at it, I could do it. I had done it. But, I needed a shower after that. Which meant getting undressed which... Logistically speaking, not feasible. What compelled Manda to open that door is unknown to us both. A certain call of the void, an intrusive thought ending in a rash action. But it's one I'm glad she made. My Thing, was still at attention, it was a little sensitive now. Sticky in the moonlit dimness. The shower had stopped at some point, the quiet buzz of her toothbrush had ceased and there came a slow creak of my side of the bathroom door. "Hey, Az? You alright?" she asked tentatively. The room was brightly lit now compared to a moment before and I tugged my shorts up. She knew what I was doing, I knew what she was doing. If she had known nothing about our bodies by that point. The crashcourse the Furflick had given her was more than enough for her to put two-and-two together. "I-I'm okay. Just y'know. Trying to think unsexy thoughts" I explained away. It was obvious those weren't unsexy thoughts. "Did... you want... help?" she nervously asked. "N-no, it'll go down before bed. I don't want to shower alone and Dad's gonna be gone so..." I'm glad my flimsy 'no' was taken for intent. The door opened wider. Her darker fur was covered in a green towels. She was bolder then. "I think that'd be a problem" she gestured, a nervous quaver in her voice. But she had entered my room, the door left wide with the pale yellow light illuminating everything. "I don't think you wanna have a talk with Mom or Dad about how you uhm... Hurt yourself." she reasoned, her mind making up a plan by the seat of her pants... Well, not that she was wearing any. She had obviously forgone reason. "We don't tell Mom or Dad, right?" I steeled myself. Finding a firmness in my voice that for a brief moment was a relief. Only for the burning realisation to come a moment later. "Right." she agreed. The gravity of those words, the pact we had just made became a reality. Her friends had stayed in the guest bedroom. Well away from us. But, she wandered over to my door, reseated the lock and turned around. I had been seated on the edge of the bed until that point. A figurative moment at the edge before I stepped away from it. 'Hupf'. "Could you look away for a moment?" I have no idea why. But I asked, she complied. I stepped out of my shorts having unhooked them once more from the pointy problem out in front. A soft swish as the lightly soiled things hit the basket. She turned around before I could give the go ahead. "Wow." was her first reaction. The reflection of light in her eyes made it all to obvious where they were aimed. The tawny glow fixated on my junk. "Your Thing is... Big." I didn't feel that was the case, I definitely saw bigger ones and when Dad I still showered together had left me with a vague idea that he was too. But neither of us was seemingly as big as the ones in the furflick we had just seen. But that was the moment it had a name. Thing. My sister had named my penis Thing. "I... don't know what to say." I acknowledged. Sitting back down and at a loss for how to progress things further. I didn't want to approach her, I felt as though I'd be removing her choice in the matter. But she stepped over. One slow foot in front of the other. Like she was stalking an unknown. Enemy or friend? Friend she had decided. The last step up towards me was as relaxed as it could be in that moment. She slipped down, her towel parting to drape over her legs. I could see she was naked beneath it. Not having even put on a pair of panties before hand. It was for better in the long run. She was kneeled down at the edge of my bed. "I dunno how this Thing works 'cause I know boys are different and all.. I've never seen a Thing up close before." she had seen them before, mine? I wondered. "You uh... use a hand. Or I guess..." recalling The Movie. "N-no. I don't think we gotta go that far." she picked up on what I meant. It stung for some reason at the time. But it wouldn't be long before we we shared a bed together. Our bed. "I saw them use their mouth and hand so..." she laid out her intent. I hadn't seen that part. But she had been standing their in front of the TV shifting between feet so... She had picked up something that burned in her mind. The air was laced with Us. The electric tingle of hormonal desire. Taboo and forbidden. But, the call was too strong at that point. She had a plan, an idea more. But, she acted on it with a hesitant false start. First, she felt around. But, her confidence in that run was dashed when I gasped and jerked back involuntarily. It was so intensely alien and foreign to have someone else touch you in That Way. "Sorry! Sorry, I didn't mean to do that." she pleaded gently. Eyes searching over me and finding that I was just as nervous as she was. She relaxed afterwards. MY green eyes following every move she made. Willing my body to obey me, 'Calm down'. I couldn't. My heart thudded wildly. My hands were at a loss. Should I reach out and... What? Put a hand on her head? Shoulder? I had no idea. I leaned back on my good wrist, knees parted. She leaned in. Words were lost between us. We spoke in that familial way. An inappropriately carnal language where our eyes met repeatedly. Her hand explored my stomach fur, my thighs, the pair of furry danglybits. She named those too. They were just my Balls. But, later on had taken over that too. "It's so warm." she mumbled to herself. Every exploratory touch was making the clear stuff come in force. Far more than I had seen before then. It wasn't lost on her either, she realised quickly how sensitive the skin was directly. Figured out that the slippery buffer let her handle it more pointedly. I was too nervous to cum, there was a tightness in my junk that was frustratingly difficult to force passed. She must have been feeling hot, I had been for certain. The flush in my ears, my cheek, nose... Everywhere was almost vesible. Her still damp headfur was loosely tamed down beneath the towel, putting off to the side. She tugged at the one around her chest with seeming annoyance until it was in a semicircle around her. I could seee the dark skinned nipples of her breasts. The the ruffled fur of her crotch. The hand she tugged away her seemingly restrictive 'garments' had returned there. She was resolved, beyond the nagging voice in head. "There." she muttered. Forgetting for a moment I existed. This was okay with me. I was a puzzle for her to work through. Her own end tidily sorted. I worked through it on my own. Quietly as I could be as she found a comfortable rhythm. A steady tempo to her movements. Her hand was the only thing up until that moment. She gestured I scoot, I did. I was leaning back even more now. Practically thrusting my hips towards her and off the bed. I lost sight of her out a need for comfort. It helped immensely as when my eyes closed. I couldn't see her naked body. The way she worked both hands between uss. My breathing steadied as I let my imagination run. Feeling the tightness ebb away until I let out my first real moan. Something that instantly made my sister wary. Maybe more excited. It was an obvious tell, progress was being made. I have no idea how long it was by that point. My eyes were still closed, my chest rising and falling at an increasing rate. I couldn't help myself as I shifted and even pushed into her hand... But then it wasn't her hand any more. The wetness, the heat, the clumsy way she moved her tongue over my Thing. She sucked, too hard at first. I winced, she read and adjusted. We moved together at that point. I wanted it, I wanted her. She was going to have me, all of me. She said I was big. But, she had no trouble with my size as I pushed up one last time. I squeaked out her name and squeezed my eyes tight. The emotional rawness of it all brought tears to eyes as I felt everything wash away in the sudden crash of wave after wave. I spasmed and tensed up. My hands flexed, the pain was intense. But it was a dull ache compared to the explosion of pleasure I had just experienced. An explosion that caught her off guard as I heard the swallow, the sudden panick that there was so much and she practically drank it down. She was clearly repulsed. But, it didn't stop the sound of her fingers. She was nuzzled into the bed. Gasping, squirming, whimpering my name. I felt the flush of hotness all over again. One last hurrah for my Thing, a small spurt that was lost somewhere between us. Her nuzzling the bed and my thigh ended with her slumping back and my scooting back up onto the bed. My arse numb from the edge of it. "Manda... Wow." was all my addled brain could manage. "Thank you." i breathed. I hadn't felt anything like that before, I'd never feel it again. But every time we were together it was close. "Az... Yeh." was her response. A simple addled agreement and we were both so enfeebled.She got up onto wobbly legs, tried to take a step. It didn't work. Her legs were jell-o. I quickly scooted onto the bed proper and she climbed in afterwards. Climbed so much as flopped in. For some reason it went further than that. The only reason we needed really. Eachother. She wobbled her in and I wrapped my arms around her. I was forced to sleep on my back anyway. It worked out, she was face to face with me and I could smell... Me. It didn't stop our eyes from meeting. Closing, muzzles turning... We fumbled our way through our first kiss, sharing that carnal moment fully. The overwhelmingly Male taste on her lips was my own. I didn't care. I found mysel fharing it with her as our tongues tied, our lips smacked and we shared potently erotic kiss. At some point morning came. We came, our friends came... looking for us. We sheepishly extricated ourself from one another. It was going to be another problem. She gestured to the bathroom and I followed. It was a tender sink-and-rag bath with a playful "Doink!" to my peeking Thing. I could hear the buzz of her toothbrush again. But not in that same way. It was seemingly just a toothbrush after that. We got dressed, we left our rooms and sat on the couch Together, hanging out with her friends until Leslie's dad scooped them both up. We were alone. Tog- Wait. When did I cum on her chest?
