My twin sister and I were home alone for the weekend while our parents were at a convention for moms work. We are 13 year old identical twin fox morphs, well identical with one exception, I'm a boy and she's a girl. This led to a lot of fun while we were young, like sneaking her into boy scouts and me into girl scouts a few times. Ever since we realized people treat you different if you're a boy or a girl we've liked messing with people's perception of us, it also means we have known about the differences between boys and girls since we were old enough to remember. We are also very comfortable together no matter what the situation is, until recently we shared a bed and still share a bedroom, not because we couldn't have our own rooms, but because we don't like being away from each other for that long. We even now sometimes take showers together, but our parents don't like it when we do, they say it's kind of creepy, but to us it's just saving time so we have more time before school or so we can goof off a little longer. Needless to say we are close to each other, so close that when she had her first heat last year she came to me first, and when I had my first wet dream I came to her, we looked it up on the internet and helped each other thru the troubles. We also made a game out of seeing who could paw themselves the quickest, and a few times helped each other.
This weekend was the first time we were going to be home alone and we were excited to be able to just do as we pleased for a few days. We both decided to just go around in only our fur for the weekend, and we decided to watch one of the movies dad hides in the closet in our parent's bedroom. We didn't know what they were or what it would lead to. Until supper we just watched T.V. and sat around on the couch, sometimes snuggling and sometimes just ignoring each other. At 6 I decided to order a pizza and Jen, that's my sister, decided to pick out the movie. She couldn't find one with a label on it so she just brought one down and laid it on the VCR. That's when we decided to mess with the delivery person and she ran up and got her cheerleading uniform. I put the skirt on and she put the shirt on, hiding the small swells that had started to form on her chest, when we heard the knock at the door she sat on the couch with her legs spared some to show she didn't have anything on underneath and I answered the door. The wolf that delivered the pizza looked like his eyes were about to pop out of his head at seeing two young vixen twins in a state of partial dress, it threw him off so much I paid with a $20 and he gave me $25 back in change. I just giggled and handed him $5 for a tip and shut the door. We cheered at getting a free pizza and flopped on the couch, I put the pizza on the coffee table while Jen put the movie in, she decided to take the top off before grabbing a slice and sitting down next to me, I grabbed a slice and we snuggled against each other, we had taken about 2 bites before the movie started. We were confused by the first part of it, neither of us could figure out why someone would make a movie about a cable repair guy, but after a couple minuets our jaws dropped as the foxes on the screen started to lick and rub each other's privet areas. We put the pizza down and kept watching, the skirt I had on starting to tent out as Jen rubbed her legs together a little.
Then we saw something we never had before, they started mating. The movie had a really good shot of the todd pushing his stiffy into the vixens slit, we turned the movie off there and looked at each other in shock, and then Jen broke the silence. "Umm, bro, do you know what that was?" I just shook my head and blushed a little before I spoke "I don't know, but they seemed to like it." she nodded and then blushed herself before giggling "so did you, I'm goanna have to wash that before practice on Tuesday" I meeped and quickly slipped the skirt off, as I looked back to her she put per paw on my hard shaft and folded her ears back. She leaned forward and whispered into my ear "I want to do that with you bro." I swallowed and whispered back "So do I sis." she then kissed my lips softly before leaning back and smiling to me "lick me first bro." I blushed deeply and nodded before grabbing her legs and gently moving them out of the way, leaning down and taking a long lick from her hot slit, the smell and taste made me shudder before I did it again, my tongue rubbing softly against her nub. She grabbed my head right then and groaned, pushing me into her more and growling. "Harder..." she started panting as I started lapping hard at her little clit, my eyes closed, her paws directing my head as I pleasured her with my tongue. She came harder then she ever had before and I shuddered softly as my senses got overwhelmed by her musk.
I kept licking until she pulled my head back and looked at me in a way I had never seen her look at me before, it kind of scared me as she growled to me "Put your stiffy in me bro... NOW!" the order made me wince a little and fold my ears back as I got up on my knees and grabbed her hips. I looked down to aim my now dripping cock at her glistening lips, a groan escaping my muzzle as I pushed my hips forward and my tip slid down to her opening. I whimpered as I stopped and managed to squeak out "Are you sure sis?" Her nod was all it took for me to push my hips forward and sink my fox hood into her deeply, a moan coming from both of us as my paws gripped her tighter and she wrapped her legs around my hips. She grabbed my shoulders and pulled me into a deep kiss, like the ones we seen mom and dad give each other. I started bucking my hips as we kissed deeply, our tongues exploring the others muzzle. My mind was a little fuzzy with the pleasure I was feeling from my sister's hot, slick passage squeezing around my stiffness. I broke the kiss and growled lustily at her before wrapping my muzzle around her throat, pounding into her as hard as I could while she was grinding her hips at mine. Before long I started feeling the sensation of my knot swelling up inside her, stretching her more and eventually locking us together. The feeling of tieing my sister was too much and I arched my back in a howl, joined by her as her tunnel started pulling and squeezing more around my knotted shaft. As my balls tightened up I started pumping my seed deep into her, neither of us wanting that moment to ever end. When it did we collapsed on the couch and nuzzled each others cheeks and neck, whispering from time to time about how much we loved each other, just basking in after glow.
