Well, Monday was slightly weird. We got to school and found out it was closed, the principle was there telling everyone the school was closed for the week for cleaning, someone over the weekend seems to have caught a bunch of wild skunks and exploded them inside or something. I dunno if that's what really happened or it was a grown up exaggeration. Kara met up with one of her friends and I think went to the mall or something. Zora wanted ice cream so I took her to the ice cream place. She had a banana split while I had a hot fudge sundae. While we were eating it started raining, a lot. So we had to wait it out. We started talking about what might really have happened at school. She had a crazy theory that a bunch soul stealing demons were inside. I told her the school always had those, they're called teachers. The kind that give out tons of homework for the weekend.. Zora giggled. About an hour later the rain finally stopped and we walked home. About the time I could see the house we were walking past a large muddy puddle, and Zora suddenly pushed me. I was caught off guard and lost my balance and fell into the puddle. Covered in the muddy water I was about to ask Zora what she did that for when suddenly she jumped in and rolled around in the puddle. I sighed, she must have gone insane. I got up pulling her up with me. “what were you thinking” I asked her. She only giggled.. we got home about the time mom and dad were pulling out of the drive way. Dad didn’t look to happy when he saw us. “what happened to the two of you?” he asked from the car. I was about to answer when Zora cut me off.. “Yami fell over and knocked us into a puddle.” Dad stared at us for a moment and sighed. “I want you both to go inside and take a shower.” I looked at Zora, “who's first?” before Zora could answer dad spoke up. “You're going to have to shower together, can't have one of you waiting around dripping wet.” he then pushed the garage door opener. “leave your clothes in the garage, try not to drip on the floor to much.” with that they drove away. Going inside the garage we closed the door. It was really weird that dad told us to shower together. Normally they try not to have us naked around each other, but I guess was a different situation, who knows what was in that puddle and I don't think they want either of us to get sick. So I started undressing, pulling off my shirt first I dropped it by the washer, Zora was pulling her dress off as I as I slide my pants down my legs, I kicked them next to my shirt. Zora grabbed the waist band of her panties and pulled them down, bending over with her tail raised high. My jaw dropped as I saw her slit and tailhole on display in front of me. I quickly turned away dropping my underwear. Did she do that on purpose..? “See you in the bathroom.” she said as she left the garage. By the time I got to the bathroom Zora was already in the shower starting to scrub shampoo into her fur.. I got in grabbed the shampoo and started scrubbing my self as well. I tried not to notice the glimpses of her slit she was giving me but well I was getting aroused anyways.. about the time we had all the muddy water and shampoo out of our fur is when she stuck suddenly pushing me against the wall, getting on her knees in front of me. “Zora, what are you doing?” I asked her. She only grinned and gave the tip of my member a lick. “Zora, don't do...” that's all I got out as she wrapped her mouth around my thing. My eyes went wide. “Zor..ah!” she started bobbing her head, sucking on my member as she did. I could fell her tongue dragging against my sensitive skin. Where had she learned this?! She never acted this way before.. I let out a moan, she started bobbing faster. All I could do was lean against the wall to keep from falling over. The warmth of her mouth felt so good I moaned again and started lightly thrusting myself into her muzzle.. it wasn't to much longer before I lost it, filling her mouth with my seed. she gagged a little at first but then she started swallowing it all, she swallowed it! I panted and she pulled away giggling. That's when we heard a knock on the door. “Are you gonna be done soon? I gotta pee..?” oh god, it was Kara! “uhm, yeah we're getting out now” I said. Zora was disappointed. We got out of the shower and dried off and wrapped our towels around us. We left the bathroom, getting an odd look from Kara but she didn't stop and ask questions she just quickly went into the bathroom and closed the door. I went to my room and got dressed. The rest of the day went by pretty normal, I play some games, watched tv that kinda stuff. Later on that day I went to the Ferret nest. We watched some movies, the first one was insane I don't even now what it was, the second movie was Spaceballs, I like that movie it's funny. But I guess toward the end I fell asleep, and someone called my parents cuz I woke up later in my room. I was pretty groggy and I felt something weird.. I didn't have any covers on and I noticed my shirt was gone. I yawned the mist was slowly lifting in my mind I squirmed, that weird feeling... that's when I looked down and instantly was wide awake. “Zora, what are you doing?!” I said in a loud whisper. I watched as she lifted her head, I saw my member slowly slipping out of her mouth.. she looked up at me smiling, crawling up onto me, straddling me. Her muzzle slowly moving to mine till they met, she kissed me, on the lips.. then she slipped her tongue in and rubbed it against mine! My eyes were wide, and then I felt it.. the tip of my member rubbing against something warm, soft, kinda damp.. She wasn't thinking what I thought she was thinking was she? I mean, I'm her brother surely... my thoughts were cut off as I felt her pushing down on me,the lips of her sex separating and wrapping around my tip... “oh god she was thinking it..” I thought, I probably could have stopped her, I could have pushed her away, but.. what if she fell and hurt herself.. it wouldn't take our parents long to investigate the noise and find us in here.. naked... Zora continued to push herself down on me her sex slowly enveloping my member, oh the warmth, she was so tight, so warm.. we both moaned into each others muzzles.. suddenly she stopped, I felt a barrier. She hesitated for a moment then suddenly he thrust down on me, letting out a whimper as I popped through her virginity.. After a moment she lifted herself up until only the tip of me thing was inside her before she lowered herself down again till it was as deep inside her as she could get it, she continued at that slow pace for a while moaning lightly as she did. She left so good.. but this was so wrong.. I moaned when I felt her pace speed up, the walls of her sex squeezing against my member.. instinct kicked in and I started thrusting into her matching her pace and rhythm. We both moaned and I wrapped my arms around, rubbing at her back gently, lost in the moment I bought my muzzle to her's. I kissed her deeply, lovingly, our tongues rubbing against each other.. Our moans got louder as our pace grew faster, more needy. She was almost bouncing on me, her paws rubbing at my chest, she moan loudly as her orgasm hit her she gripped my fur tightly, almost painfully to me. The feeling of her sex quivering and squeezing me set off my own orgasm, my seed going deep inside my sister, a place it shouldn’t be in.. she collapsed onto me exhausted. We hugged each other tightly and fell asleep. There was a knocking on the door. “Honey, is Zora in there? I can't find here anywhere.” No! It was mom.. I felt Zora nuzzle at my neck. I had to think fast.. “ Uhm, yeah, she's in here.. we're uhm.. we're playing a game.” I said quickly. I heard mom trying to open the door.. “The door's locked.” she said.. “Is it?” thank goodness Zora locked the door when she came in... “we're in the middle of something and can't pause.” “well, breakfast is almost ready.” she reply. “Ok we'll be done in a minute.” told her, letting out a sigh of relief as I heard her walk away. I give Zora a hug.. “Get off and get dressed before we get in trouble..” I told my sister. She wasn't to happy, she she got up and moved over to her clothes, she saw I was watching so she bent over lifting her tail up so I'd see her slit. The fur matted the sex.. she let out a giggle and got dressed. I sighed getting out of bed and getting dressed myself.. Man. I'm so dead if my parents find out..
