My Makayla Codes: Mg(12), inc, oral, anal, cons. Summary: A man and his niece grow closer over the summer. My niece Makayla was absolutely beautiful. At just 12 years old, she was already a knockout. She was 5'2", and had already started developing a small set of A cups. It was hard pretending not to notice. I didn't want to go from the cool uncle that she wants to visit, to the creepy one nobody wanted to invite. This worked out well as Makayla decided to stay with me for a month while her parents went overseas to visit family. I woke up one morning to my doorbell ringing. I open the front door and am immediately slammed by a bundle of pure blonde energy. I pull Makayla into a hug. I see my brother and his wife in the car, waving. They didn't even bother getting out. Though I wasn't surprised. They tended to procrastinate, and were likely about to miss their flight. I waved goodbye to them as they sped off. "Okay sweetie, I'm gonna need to breath soon." I say, pulling Makayla off of me. "So, how are you? Ready for a month of us annoying each other?" Makayla giggles as she gets off me to pick up her things. "I'm doing great, uncle." That's all she ever called me. Never my name, always uncle. Not that I minded too much. "So, what do you feel like doing?" I ask her, already knowing the answer. "Swimming! Swimming! I wanna go swimming!" She shouts enthusiastically. I had a swimming pool in my backyard. It was a pretty worthwhile investment. Nothing get's girls faster than offering a dip in a private pool. It also meant that I had in excuse to get Makayla into less clothing. I dropped her things off in her room and went to change into my swimming trunks. I head back downstairs, checking on the pool. As I hear the back door open, I look up. My jaw hits the floor. Makayla steps out wearing a tiny string bikini. They're a solid red color. It stuck to her tightly enough that I could see the outline of her breasts. When she turned to close the door, I got a view of her ass. As though the bikini was molded to it. Not wanting my erection to be shown, I immediately jumped into the water. I soon hear a scream and feel a splash as Makayla jumps in next to me. Giggling, she starts trying to splash me with water. I chuckle a bit before hitting her with splash after splash. "Stop, I give up. Uncle! Uncle!" She laughs while shouting. I stop splashing and we just swim around for a bit. I use any chance I can get to dive under the water and check out Makayla's 12 year old ass. There's also plenty of opportunities for grabbing and "accidental" groping. After nearly an hour of pool fun, Makayla gets out and dries her self off. She sits in a lawn chair, grabbing some sun tan lotion. I watch transfixed as she rubs it slowly onto her legs and arms. I want to go up there and take over for her. Just rub my hands all over her body. As Makayla turned to me and spoke, I started to wonder if there was a patron saint of horny uncles. "Hey, Uncle? I can't reach my back. Could you help?" As I get out quickly grab a towel and wrap it around me to hide my erection. Makayla lies down on her stomach. I put a generous amount of lotion on my hands before bringing them down gently on her back. I start moving my hands up and down Makayla's back. This was the sort of thing I already had plenty of experience with. Though, none were ever quite as young as Makayla. I start moving my hands lower, to just above Makayla's ass. Her bikini had tightened on it a bit. Some of her ass poked out from the top. Not that it made much difference, I could clearly make out the sight of her crack through the red fabric. I began moving my hand down, barely touching her exposed area. I heard Makayla giggle. "Not there Uncle. Move up." She said. "Er, right sweetie, um I'll be right back, just gotta get more lotion." I quickly ran inside to my room. I pulled my boxers down to release my now raging hard on. Giving it a quick squeeze I started pulling it. Just as I was getting close, I see Makayla run into the room. "Uncle where'd you go? The bottle still had a lot of, oh!" She stopped dead in her tracks, looking directly at my member. "Crap! Uh, Makayla, look I'll be down in a second just, um go!" I started shouting as I tried to shove my dick back into my pants. "What's that Uncle, what were you doing?" She wasn't going to leave it alone. I tried to hide my erection, but that was proving fruitless. She got closer to me, looking right at it. "It's my dick, have you never seen one?" I decided to just try playing it cool. Who knows how it might turn out. "Not in real life, I've seen them on the internet though" She now has her face right next to my dick. "I thought it only gets hard when you want to have sex though." "Well, um kinda, I suppose I do" I responded, not wanting to get into random boners and all that info. "I'm the only one hear though. Did you want to have sex with me?" As she asked this, she looked right up at me. Shit. What would she say? She didn't look nervous about the idea. Maybe she would go along with it. My dick regained it's hardness at the idea. 'Yeah, but usually only women want to. If I do have sex, then people would think I made you do it. It would be bad for me." "I won't tell!" She shouted out as she jumped up with a smile. That caught me off guard and I took a step back. "Really? You want to?" "Yeah, you're supposed to do it with a guy you like and love. You're both those things Uncle!" That was all the incentive I needed. I stood up and pulled my boxers down. My dick sprang out, almost like a dog wanting to say hi. I'm quite proud of it. 8" long and nearly 2" thick. It's more than enough for most women. I started wondering how much Makayla could handle. "Alright then Makayla, why don't you take off your bikini?" I asked her as I toss my boxers to the side. "Okay, Uncle!" She shouts enthusiastically. Makayla reached behind her and began to untie her top. I swear it fell to the floor in slow motion. Her breasts were amazing. Small, but perfectly fit for her petite body. The nipples were tiny, but only added to the appeal. Next she untied the string on her bikini bottom. I was greeted by the sight of a tiny slit, with the smallest beginnings of pubic hair forming. "You're so beautiful, Makayla." I told her as I hugged her. "Ah, thanks Uncle." "Why don't you give your uncle a kiss sweetie?" I asked as I puckered my lips. Makayla gave another tiny giggle, as she moved to me and gave me a kiss on my lips. I pulled her into it. I broke away and looked down, my dick was about ready to explode and really needed some relief. "Makayla, can you give me a kiss here too?" I asked, pointing to my huge member. "Oh, you mean like they did in the videos?" She asked as she bent down on her knees. "You've seen those types of videos? Can you show me what they did?" I hoped her eagerness to show off would come in here. "Okay!" Makayla said, as she took my dick into her hands. Those already petite hands looked even smaller wrapped around my cock. The wave of pleasure that I felt when she touched it caused me to thrust forward. Makayla must have studied those videos a lot, because she was a natural. She started by planting a few light kisses up the length of my shaft and then at the tip. My little niece then stuck out her tongue tentatively. She gave my shaft a quick lick before pushing a few inches into her mouth. "Urgh, damn Makayla. Your an expert at this. Probably the best I ever had." I grunted, looking down at her. Makayla looked up at me with her eyes wide from the praise. She managed a smile while moving her head up and down my shaft. I could feel myself getting close and decided to warn her. "Sweetie, I'm... ugh. About to cum. It means my sperm is... oof... is gonna shoot out, you may want to move back." To my surprise, she instead moved in further. My ball sack practically exploded as shot my cum into my nieces throat. Surprising my further, Makayla managed to swallow most of it, with only a small trickle being left on her mouth. I pulled her up to me, putting the small bit on my finger. I moved it to Makayla's mouth. She opened wide and sucked the jizz right off. "That was good!" Makayla rubbed her tummy while talking. "I heard some people don't like it, but I think it tasted nice. "That was great Makayla, would you like me to return the favor?" "How? Do you mean you're going to have sex with me?" "I'd love to sweetie, but I need some time to recover first. Let's do something else until then." I grabbed Makayla's hand and led her to my bed. Laying her down on it, I got down on my knees in front of her pussy. I took a deep smell of it. There was a small hint of chlorine from the pool. Spreading her pussy lips slightly apart caused Makayla to give a tiny gasp. "That feels good uncle." "This is going to feel better, sweetie." I brought my tongue to Makayla's pussy, quickly finding her clit with it. She let out a loud moan as I started licking her up. I gave her pussy a tiny nibble, just enough to put some pressure on it. Moving a hand up I managed to locate Makayla's left breast and gave her nipple a slight twist. "Ooh. Uncle, that is even better. Mmm uh aaah!" Makayla shouted out in climax. I moved up next to her. Makayla smiled at me with a dreamy look in her eyes. She moved over giving me a quick peck on the lips. After a few minutes I got up. "Where are you going?" She asked, looking worried that I was leaving. "No where sweetie, it's just that I'm ready, and wanted to move on to the next step." I picked her up as I sat back down. Putting her in my lap, facing me. "Are you ready?" Makayla nodded enthusiastically. I grabbed some lube I also kept in my drawer and stroked my dick with it a bit. Slowly, I lowered Makayla down on to my dick. The lube helped, but it was still a tight fit. I kept pushing in, expecting to hit a wall, but was surprised when I didn't. I was too caught up on being inside the object of my lust to care at the time. When I asked her later, I learned that she had broken her hymen horseback riding. Grabbing Makayla's hips, I started moving her whole body up and down. As the pace quickened, I began to thrust my own hips, until eventually I was managing to fit most of my 8" dick into Makayla's 12 year old pussy. As I heard her reach her second orgasm of the day, I pulled out quickly. I reached my own climax immediately after. Spraying Makayla's stomach and legs with my seed. I sat her down properly in my lap while hugging her. "How do you feel sweetie?" "Good, tired, but good." She responded, laying on my chest with her eyes closed. "You really are the best little niece in the world." I muttered before giving her a kiss on the cheek. The rest of her month long visit went by too fast. Almost the entire time was spent at the house. We fucked in the kitchen, the shower, even the pool once (though we almost got caught there). Through out this, we had done almost everything we could with our hands and privates. Doggy style, 69, cowgirl was especially fun. The one thing I didn't get to do was her ass. She always dodged the subject whenever I tried. I didn't want to push it, so I just let it go. On the final night before her parents were coming to pick her up, Makayla called me into the room we were now sharing. When I went in, she was wearing the little red bikini that all this started over. Well, rather, only the bikini bottom. "What is it sweetie?" I asked her, excited about what she had planned. "I have to leave tomorrow. So I was saving a special present, just for tonight." She responded with a playful grin on her face. Makayla turned around and untied the string, letting it drop. She bent over the table, slightly spreading her ass. She turned her head and gave me a tiny wink. I practically run over, nearly tripping as I do. Stopping by the drawer, I grab my bottle of lube. I apply some liberally to my now completely erect dick, before rubbing some extra all around my niece's ass cheeks. Grabbing her cheeks myself, I slowly position my dick to her asshole. "You ready baby?" I can barely stand the wait. "Please Uncle, I want it." I push into her asshole, It needs a bit of force to go in, and I hear Makayla give a small gasp of pain. I give her a few seconds to let her get used to it before starting my movements. Her ass is incredibly tight and I have to move slowly. Even though we had been consistently having sex the entire month, it didn't take me long at all to feel myself getting close to coming. With one last push, I managed to get about 6" of myself inside Makayla. Makayla was ever a bundle of surprise. Just as I came inside her ass, I heard her give a now familiar moan that let me know she just had her own orgasm. Pulling out of her, I pulled Makayla to our bed and lied down. We woke up the next morning to my phone ringing. It seems my brother was on his way to pick up Makayla. We spent our last 15 minutes as a couple in the shower kissing. Makayla quietly got dressed and packed her stuff, sad that she had to leave. We met my brother outside. "Hey man, was Makayla good?" He asked, giving me a hug. "The best. She really is a sweetie." I said, trying hard to hide what I really meant. "That's good to hear, I'm glad she wasn't any trouble." He chuckled before speaking again. "She even looks sad to be leaving, herself. Maybe me and the wife should leave her with you more often." "Not a bad idea, tell me. What are your plans for the winter break?" I asked, looking forward to the next time I would get to babysit my Makayla.
