“Hey Mom, you’re really good at baking, do you think you could ever be in one of these baking competitions?” I asked looking up at my mom. My head was in her lap, we were on the couch doing what we love on a wednesday night: being lazy on the couch and watching baking shows. 
   “I don’t know, my baking is more of a hobby, I don’t think I could have what it takes to compete like that.” She ran her fingers through my hair. “Maybe we can get some of the mothers together and we can have a competition like that one day.” 
   My tail started to wag, “I think that would be pretty cool.” As we laid there, watching a sheep woman make a tiramisu that I wish I could reach through the tv and eat, my mom went from running her fingers through my hair to putting her hand down my shorts and started to feel up the front of my diaper. I blushed a little as her hand massaged the front of my diaper. “Mom. Come on. I told you only between the commercials.” I said as I squirmed on the couch. Her hand was bigger than most adult women. She was able to easily cover the front of my diaper as she rubbed it. 
   I know, but since it’s just you and me tonight. I figured why wait.” It was just mom and I tonight. Dad, Billy and Mike were on a camping trip with one of dad's friends. Sally and Kerry were in her room all night. They usually don’t like being disturbed unless it was for a diaper change. Mom and I like having these kinds of nights. We get to mess around. She always takes charge on nights like this. It turns me on like crazy. 
   “Mom, should we do this in the living room?” I asked as she slipped my shorts off. 
   “I don’t see why not. It’s just us here.” She said slipping off my shirt. “Besides, it’s always a little more fun when it’s not in a bedroom.” She went back to feeling up the front of my diaper. “How's that little pup? Does it feel good?” She knows I love getting the front of my diaper rubbed almost as much as I love doing it to someone else. 
   “Oh mommy,” yes. I started calling her mommy in moments like this. We had a bond like that. “Oh mommy, it feels amazing.” Billy didn’t like our parents' hard scales sometimes. He said they hurt when they rubbed against his fur and down to his skin. It didn’t bother me. I don’t know why,but I kind of liked it. 
   As mom continued to rub the front of my diaper I started to feel my sheath start to swell and my dick start to emerge from it. She could feel it through the padding and focused on that as she rubbed. “Cum for me little pup.” she whispered in my ear.
   I let out a moan as my dick was rubbed with my wet padding. I didn’t know how long I was going to last but I knew this was going to be a good orgasm. I thrust my hips a little into her rubbing, just as I was feeling an orgasm start to build up, we got interrupted.
   “Mom” we both heard Sally call out. Mom stopped and we both looked over to the entrance of the living room near the stairs. “Mom, I know you and Jay are having some alone time but Kerry and I need a diaper change.” She said, stepping into the living room. 
   Mom gave a sigh and set me back onto the couch. “Okay, go get Kerry, bring some diapers and I’ll change you in here.” She said as she started to get off the couch. 
   “Actually mom, Kerry and I were wondering if Jay could change us, up in my room.” 
   Mom sat back down and thought for a second. She turned on a light by the couch and looked over at me. “Okay, he’ll be up there in a moment to change you and Kerry.” Sally perked up a little and thanked mom before running back up the stairs.
   “Mom, do I have to?” I whined a little. 
   “Honey, I’ve been around for a long time, and your father and I have fostered a lot of children. I know when a girl wants a diaper change and when they want a little more.” She said turning over to me. “Now I don’t know if that’s what they want, but remember one very important thing. Whatever happens in that room tonight. If one of the girls says no, you respect that. Understand? She said in a more stern voice. 
   At first I didn’t know what she was talking about. It hit me when she reminded me that no means no. “Yes mom, I understand.” I said as I picked up my shirt. 
   “Oh sweetie, you’re not going to need that.” She said getting up from the couch. “You go be with the girls, I’m gonna get a vibrator.” She said ruffling my hair and walking off.


   When I got up stairs, I knocked on the door, a second later it flung open. Kerry was the one who greeted me. She and Sally were wearing long nightgowns, both were pink. “Hey Jason.” She said, looking me up and down. The only thing I was wearing was a wet diaper. “Come on in.” She said stepping out of the way for me to come in. 
   “Okay, so who do I change first?” 
   “Why don’t you change your little sister first? Over here on the bed.” She motioned me over to Sally’s bed.  
   I smelled the air. If it was a diaper change with something more than at least I didn’t have to change any poopy diapers. I looked over at Sally, from the way she was looking at me and fidgeting with her legs a little I could tell she was ready for some sexual touching. 
   “Okay, I know I wasn’t called up here to do a diaper change. What do you two really want?”
   Kerry came up behind me and put her hands on my butt. “Well we were fooling around a little up here, I asked Kerry if she had been penetrated yet and she told me no. I asked if she would ever want to be, and she said only if her big brother Jason could do it.” 
    I looked over to Sally who was now sitting on the bed with her legs open. The front of the nightgown was covering her crotch but I could tell she was ready for something. “Why me?” Don’t get me wrong I was flattered, I wish I could have chosen my first. 
   “Well it was the first night mom and dad showed me what sex was like. Your dick didn’t go inside me, and since you were the first to touch me there when it wasn’t a diaper change. I want you to be my first.” 
   I started to get hard again. Sure there was the time where I rubbed my erection along her pussy and the times I rubbed her till she orgasmed, but to get to take her virginity and her giving it to me, was something I hadn’t done. 
   I walked up to her and pulled her up from the bed and started to kiss her. Billy and I had taught her how to french kiss. I loved how she masturbated to us kissing. I pulled her nightgown up and pulled it off of her. When it was off I went back to kissing her and let my hands go down to her diaper. I pulled the tapes and let it fall to the floor. When the diaper was off I moved her to bed. She scooted back and laid back with her legs open. Her pussy was wet, and not just from the wet diaper she had on. 
   I got down on my knees between her legs and went to lick her little pussy. I could almost taste the arousal in her fluids. I held onto her hips as she writhed on her bed. Mixed in with her moans I could hear crinkling. It wasn’t my diaper, so it had to be Kerry masturbating to what I was doing to Sally. 
   After a few seconds of eating my little sister out, her legs clamped together on my head. A little explosion of juices came from her pussy and gushed onto my muzzle. I licked up what I could and from my mouth but left her juices coated on her pussy.  
   Since I knew a girl's first time could hurt without some preparation, I gently slid my finger into her pussy. I heard her moan again as it slid in and met some resistance. “It’s okay Sally, just relax.” I said rubbing her inner thigh. As I felt her walls get used to my finger I gently slipped in a second. Again she moaned from the pleasure I was giving her but met resistance with her vagina. 
   When I felt she was ready, I stood up and pulled the tapes on my diaper and let it fall on the floor next to Sally’s. I crawled over to Sally on her bed and got into position. I told her to hold her legs under her knees and hold them apart for me. I lined up my cock and pressed the tip of it to her entrance and put my hands on her waist. 
   I looked down at her expecting to see a scared little girl looking up at me. Instead I saw my little sister, looking back up at me with expectant pleasure and a look in her eye that was willingly asking for it. “Are you ready Sally?” Sally put her hand on my chest and nodded. 
  Gently I pushed my hips forward. My tip easily slid in, as it widened I felt resistance again. I continued to gently ease my cock in. with one good thrust I felt a small pop and my dick slid down to my forming knot. Sally cried out in pain as she was penetrated for the first time. I rubbed her chest as she came down from the sudden shock of being penetrated. 
   “It’s okay big brother keep going.” She said through some light gasps. 
   I nodded and gently rocked my hips. Thanks to her orgasm a few seconds ago, she was nice and wet. I was gliding in and out of her with ease. 
   I picked up the pace a little. The rubbing mom was giving me earlier along with eating Sally out  had me edged out, I was very close to cumming. Back and forth my dick slid in her no longer virgin pussy. She was tight, she felt amazing. Each thrust forward I could feel my knot growing and slapping her little pussy lips. The wet sounds of the slapping were driving me crazy. 
   “Big brother, I’m…. I’m gonna….” She came again, this time her pussy walls clamping down around my cock. With the pressure around my dick I thrust forward again and pushed my knot past her lips and into her pussy. She screamed out in pain and I cried out in pleasure. 
   Rope after rope of cum shot from my cock and painted the walls of my sister's pussy. Quickly the pain from my sudden knotting subsided in my sister as she felt her big brother cum flood her pussy. 
   As I rode out my orgasm I leaned forward to my sister and kissed her. “I hope that was everything you wanted, little sister.” Sally didn’t respond. Her face showed everything, she was riding out one hell of an orgasm. 
   Looking down to our connected crotches, I knew my knot would not be free for a while. I held Sally close and rolled onto my back. She laid on my stomach and hugged me. I looked over to the other side of the room. Kerr was on the other side of the room laying on a pile Sally’s plushies.  
   Sally lifted her head off my chest and gave me a kiss. “That was, amazing big brother.” she laid her head back down and tightened her hug. “Thank you.” she said, nuzzling her head into my chest. 
   “I’m glad I could be your first kiddo.” I said, hugging her back.


It had been about two weeks since I had sex with Sally for her first time. We were in the park down the street from our home. One of Mike’s friends was having  a birthday party and we were there to celebrate. I was talking to a 10 year old fox, who I was planning on having some alone time with. He was a cute little fox with a lithe body. I was told he was also a good power bottom. 
   While we were talking I put my hand down the front of his shorts and started to feel up the front of his diaper. Just as I was about to start kissing him. My little brother Billy came over to me and put his hand on my shoulder. 
   “Hey, Sally said she needs to see you by the slides.” He said pointing over to the slides. 
   “What does she need, I’m a little busy.” 
   “I don’t know, she just said she needs you.” He said walking away.
   I looked over to Chase and told him to wait a minute. I told him she just may need a diaper change. 
   I walked over to the area where the slides were and looked around. I didn’t see her anywhere. I looked under the slide and saw that she was nowhere to be seen. “Sally.” I called out for her. A second later I heard her call back. It sounded like she was in the bushes next to the slides. I knew there was a clearing there. Some kids liked going there because it was a little secluded for having sex. Most parents knew about it but left everyone alone and let them explore their ex\obitionist kinks.
   I walked into the clearing to see my little sister bent over a small boulder. The back of her dress was pulled up revealing the back of her diaper. Almost instantly Today I was planning on having sex outside but not with Sally. 
   “Big brother, I need help. I’m so horny. I need your big cock.” She said looking back. “Please help big brother.” She said, shaking her ass at me. 
   I walked up to her and gave her padded ass a good swat. She moaned in pleasure. “Such a good kitty, getting horny for her big brother's cock.” I pulled the back of her diaper down revealing her nice hot little pussy. Her smell was intoxicating. I gave her hot little pussy a few licks before standing up and pulling my shorts down and letting them fall to the floor. I pulled down the front of my diaper and let my cock spring forward. I lined my tip up and slammed forward. Ignoring her pain, something was driving me to fuck her as hard as I could. I gripped her hips and continued to pound her tight little pussy. 
   Sally went from pained groans from the speed and force I was pounding her with the pleasured moans as her body rocked on the boulder beneath her. “Oh yeah little kitty you like that? You like big brother fucking your tight little hole?” I let out. It was strange I had never talked like that before, maybe it was the fact that I was outside. 
   “Oh big brother, it feels so good.” She called out.
   After a few minutes I felt my knott swelling up, I didn’t want to knot her in public, who knows how long it would take for it to go down. I also wanted to go and mess around with that cute little twink of a fox. 
   I pressed my engorged knot against Sally's little lips and tried my best not to let it pop in, which was hard since her pussy was soaking wet. I gave it a few pumps, the velvety walls of her pussy clamped down around my cock and started to milk it. I grunted and started to cum. My dick twitched and a few ropes of cum shot from me and into Sally. The orgasm was one for the books. The intoxicating smell coming from Sally combined with her soaking wet pussy. Doing it outside was just icing on the cake. 
   I pulled from her pussy and put my softening dick back in my diaper. I immediately felt myself peeing after the orgasm. Sally was still slumped over the rock, her pussy out in the open. I bent down to fix her diaper. I gave her pussy a sniff. She still smelled amazing so I started to eat her out. The taste of her amazing juices and my cum made for an intoxicating treat. Before I knew it I made her cum again. This time I gave her a few licks to clean the juices on her lips and pulled the back of her diaper up and secured it. I walked with her to the jungle gym where her friends were and let her sit there with them. After she was set I went off to find the little fox boy and see if that white on his chest went all the way down.




It’s been about a month since the park. Mom, Sally and I were in the living room watching TV. Mom was on the floor changing Sally. I was looking at something on my phone. 
   “Wow baby girl, I think it’s time we lay you off of the sweets, your belly is getting a little big. Your diapers are getting a little snug.” She said, tapping up Sally’s diaper. 
   I looked over, mom liked to joke that we were getting too big for our diapers but this time she sounded like she meant it.
   She poked and prodded at Sally’s slightly bigger than normal belly. Sally just giggled and squirmed. Mom was looking a little concerned. “Sally, remember those special times Mommy was telling you about?” Sally nodded. “Do you remember the calendar we made so you know when you can’t have sex with anyone during that special time?” Sally’s face went from a happy giggle to neutral expression. She nodded again. “Baby,” Mom's voice had a lot of concern in it. “Did you have sex with someone anywhere after the start of the calender?” She nodded again. 
   “Jay and I had sex at Mike’s friends birthday in the park.” she said looking over to me. 
   Mom looked at me like she was ready to kill me. Just as I was about to ask what was wrong, Mom's expression changed and she looked back at Sally. At that moment I knew what was wrong, I knew what I had just done and I didn’t know she had started. 
   “Well Sally, the reason you belly is getting bigger is because you had sex in your heat, and now you’r pregnant, and Jay is the father of your kitten.” 
   I literally shit myself when she said it out loud.
