KEEP IT DOWN IN THERE!

My name is Kevin, but my friends all call me KJ. That is because our last name is Smith, and I'm not that Kevin Smith. You know that guy, Silent Bob? Anyway, I grew up in a predominantly white suburb in the Midwest. Our family never moved or did anything that exciting. My dad had a steady job in an office building. My mom was a typical mom. She wasn't some crazy hot MILF or anything like that. My sister...well, my sister was a problem.

My sister and I have fought our entire lives. Seriously, I cannot recall a time that Katie and I ever got along. I am almost two years younger than she is, but that meant I was only a year behind her in school initially. She got really sick several times in the sixth grade and wound up repeating, and from then on we were in the same grade. I would have felt sorry for her, but she was perpetually such an unbelievable bitch to me and my friends that we would just fight instead.

Now, when I say 'fight' I mean verbally. Katie grew early and towered over me until we were well into high school. I was short for my age and only caught up to her late in our junior year. We both have blonde hair, blue-grey eyes, vile tempers, and a knack for pissing each other off. As you can imagine, that doesn't sit well with our parents. Every summer from the sixth grade on, they packed us off to camp just to get us out of their hair for two months. Not the same summer camp, so we actually got a break from each other as well.

Katie was just insufferable our junior year of high school after she got her car. It would have been nice just to have her off of my case and independent, but our parents insisted that she had to drive me to school every day. Katie resented the hell out of me for that, and I resented the way she bossed me around when we got up to get ready for school.

I did feel fortunate that I hit a growth spurt in that junior year. I went from five and a half feet tall to six foot even over a five month span. The thing about growing quickly like that is that everything is growing at the same rate, but you just don't notice it. It's not like I woke up one day and I was suddenly taller than my sister. What you do notice are annoying things like your favorite t-shirt no longer fits, or you have to get new shoes and they hurt your feet until you break them in.

I felt uncoordinated all the time, and I was already way too shy around girls. That didn't help. It also didn't help that my sister was constantly jumping into my personal life and embarrassing me when I would work up the courage to actually talk to a girl. Worse still, my sister made friends with all the crazy-ass fine girls in my school. There was a pack of them that hung out, and they were just vicious to me and my friends. I tried to stick up for my friends, but those girls were intimidating. Naturally, I wanted to fuck every one of my sister's friends, but that was never going to happen.

We graduated the eleventh grade and got shipped off to camp again. At my summer camp, I got to be a camp counselor for the first time. I got to teach canoeing, kayaking, and basic boating skills to a bunch of younger guys. I had known a lot of them from previous summers at camp, so it wasn't a big deal. I wasn't shy about teaching them and I knew what I was doing.

Unlike previous summers, I spent the entire two months doing nothing else. I was on the water, paddling people around, carrying the canoes, kayaks, and rowboats to and from the water, or swimming every single day. By the time camp ended, I was really tan and substantially stronger in my upper body than ever before.

I don't know what Katie's camp had her doing. She got home a day before I did, and she was off with her friends when I got home. We did an outstanding job of avoiding each other for the last three weeks of summer vacation. By that time, I often stayed over at one of my friends' houses, and Katie stayed over with one of her friends more often than she was home.

At least that was what we all thought.

It turned out that Katie had a steady boyfriend who had his own apartment. She was nineteen, and so was he. He had graduated a year ahead of us, had a job, and had my sister in his bed most nights. Even had I known, I would have been fine with that—it kept her from bugging me all the time. It's not like I was some guardian of my sister's virtue.

Of course, Katie messed up and got herself busted by our parents. Somehow, I wound up in trouble for it.

It started with my parents taking me aside and interrogating me about Katie and her boyfriend, Bryan. I didn't know anything, but that didn't stop them from really pissing me off by asking a thousand questions about my sister's personal life. Finally, I just snapped at them.

"Come on!" I said, a little too loud, "Katie is an adult, now. I'm not. How could you possibly expect me to know what she does with her personal life? She has a car, and I don't. She has friends who are adults now, and I don't. What do you expect me to do, follow my sister around and report back to you?"

As soon as I said that, and saw the looks on their faces, I knew I had fucked up.

That was exactly what they expected, from then on. They brought Katie in, and laid down the rules for our senior year. We were never allowed to go out without the other one being there. If we didn't like it, we could both just stay home. Those were our only two options for the next year.

Katie lit into me right after our parents left us alone.

"What the hell did you say to them?" she demanded.

"Whoa!" I shot back, "They were asking me about you and Bryan, and I didn't know anything! I told them you are an adult, now, and they didn't like that. I told them I wasn't your keeper. I guess they decided I will be from now on. I'm not happy about this either. Do you think I want you hanging around with my friends?"

"Your friends?" she sneered it at me, really pissing me off, "I wouldn't be caught dead around those losers. Now I can't even hang out with my friends without dragging your sorry ass along."

"Well, I guess you won't have to worry about that," I spat back at her. "I wouldn't hang out with those stuck-up bitches if you paid me. I guess we'll just be staying at home every day for the next year."

I turned and stomped out after that.

I think my mother overheard some of that. She is a stay-at-home mom, and I think the prospect of having me and my sister at home and at each others' throats for every single day of the next year terrified her. She approached me that evening, trying to talk to me in a soothing voice. She was really trying to be reasonable. I was just too angry and thick-headed to hear her out. After a lifetime of hearing her soothing voice, it just got on my nerves when she tried to talk me out of being mad and stupid.

Oh, I get all that now. Years later, I realize how smart and caring my mother really is. Back when I was a teenager, though, I thought she was just clueless.

For the remaining three days of summer vacation, Katie and I stayed around the house. Three or four times a day, we would get into a screaming match. Our parents wouldn't even bother to come into the same room. From wherever they were, we would hear them holler, "Keep it down in there!"

Usually, that would be the point that we would break off our arguing and just glare at each other before we walked away. A couple of times, we were so into our screaming match that we didn't hear our parents until the second or third time they yelled at us, at which point they would start threatening us with some dire punishment. We never pushed them to see if they would actually do it.

Our senior year finally started, but that didn't put an end to our fighting. The morning of our third day of school, Katie barged right into my room while I was getting dressed. I was pissed off, still barely awake, and I was only wearing my underpants.

"Jesus, Katie! Don't you even know how to knock?" I yelled at her. She looked stunned.

I expected her to insult me, yell at me, call me a jackass, or something like that. Instead, she just said quietly, "We need to leave in twenty minutes. Mom's got pancakes on if you're hungry." She closed my door behind her and was gone.

Quite frankly, I didn't know what to make of that. I pulled on some clothes for school, ran a comb through my hair, and hustled out to the dining room to wolf down some pancakes before we left. My mom was the one who gave me grief for my beastly eating habits.

Katie was quiet in the car all the way to school. I barely noticed that because there were a pair of songs I really liked on the radio, and then we were at school. I hopped out of the car and ran off to meet up with my friends before classes started. At the end of the school day, I was waiting at Katie's car when she walked up with two of her gorgeous friends, Natalie and Annette. I bristled, preparing for the inevitable insults...but they never came.

They just looked at me, and then they talked quietly for a bit. Natalie and Annette left, and Katie came over and unlocked the car. I was feeling a little paranoid, and checked myself in the mirror. No obvious problems that I could detect. No booger hanging out of my nose or anything like that. I looked over at Katie as she drove. She just kept her eyes on the road and drove us home.

When she parked the car, we both got out and went into the house. It was the first time I had homework for that school year, so I figured I would just get it done. I went to the dining room table and spread out my books and papers and stuff from my back pack, grabbed a soda, and got to work. It only took a half hour, and I was done.

That was kind of a big deal to my mom. I had always been a procrastinator, especially when it came to my homework. When I finished and started putting everything back into my bag, Mom came up to the table.

"Did you just finish your homework?" she asked.

"Yeah," I replied, not sure what she was getting at.

"Wow," she breathed, "That's great."

I got it then, and had to smile. It did give me an idea, though. Maybe if I could keep that up and convince my parents that I was more responsible, they would let me out of being Katie's watchdog.

Katie's friends showed up, then. The entire pack of them. I bailed for my room and locked the door. Katie's room was on the opposite end of the house, so I figured I was safe from their verbal daggers.

I got onto my computer and played games until supper time. Everyone was surprisingly pleasant at supper that night, including Katie. I just said nothing and ate my food. It was really good, and I made sure to compliment my mother on it. It was my night to do the dishes, so I did that when everyone was finished eating. While I was washing the dishes, I could see them watching television in the living room. The sitcom was one of my favorites, so I hurried to finish the dishes so I could join them.

The show was hilarious that night. We all laughed. I was sitting on the opposite end of the couch from Katie, while our folks occupied the loveseat. The next show was decent—not as good as that first one, but we sat through it and enjoyed it. We all turned in afterward.

The next three weeks pretty much went like that. Some of Katie's friends would come over for a few hours after school, and I would avoid them. I got my homework knocked out first thing every day. We all watched TV as a family. School was pretty boring for the most part. I did manage to talk to a couple of girls without embarrassing myself. I couldn't exactly ask any girls out on a date, and everybody was aware of the rule regarding me and my sister.

Then it was the weekend of my eighteenth birthday. I invited all my friends over. A few of them had dropped by to visit, but had bailed when my sister's friends showed up. We all felt like we had scars from dealing with them in the past, so I totally understood when they panicked and left. I was still pissed about it, but didn't feel like there was much I could do.

At any rate, four of my buds came over for my party. My parents were going to be there, so it was going to be lame. Still, we were all surprised when Katie's friends all arrived for my birthday party. Let me tell you, my friends were nervous as hell. So was I, honestly. But then the strangest thing happened. Those girls, every insanely hot one of them, were just as nice as could be.

They didn't try to embarrass us. They weren't even the least bit insulting. They smiled and talked to us and laughed. We were just bewildered. We also suspected it was a setup.

It was a setup, of course. There was no way those girls could change that much after all those years without an ulterior motive. I just had no idea what that motive was.

The next Monday night, I felt like my suspicions were confirmed as Katie and Natalie burst into my room. I blamed myself for failing to lock the door, but I hadn't done anything to antagonize them that I was aware of. Katie's voice was shrill and loud.

"What the hell, KJ?" she hollered at me, "Here I give you a ride to school every day, all my friends came over for your lame birthday party, and we were even nice to you! We didn't pick on your friends, Sarah bought you that nice shirt, and this is the thanks we get?"

I was befuddled, but my reflexes kicked in and I shouted back, "What is wrong with you? You just barge into my room and don't even knock, like, ever! Now you're dragging your friends along..." I lost steam, then, as Katie and Natalie just grinned at me. I cocked my head at that. What the hell was going on?

Then, from across the house we heard, "Keep it down in there!"

Natalie pulled my desk chair out and sat in it. Katie sat on my bed and patted the spot next to her. She said quietly, "Have a seat, KJ, we need to talk."

I sat down, but I was nervous as hell. Natalie might just be the most attractive girl in my entire school. She and my sister have been friends for years. Natalie had certainly insulted me and my friends plenty of times over the years. Now the two of them were here in my room, and they seemed to have a plan. Quite frankly, I was prepared to run for my life if I had to.

I did sit next to Katie, though.

"Bryan broke up with me," she said. Her voice was soft, but she didn't seem all that emotional about it.

"I'm...sorry?" I said, not sure what she wanted me to say.

"Thanks, KJ," she said. She was actually looking at my eyes and smiling sadly as she said it. "I'm not that upset about it now. We were just hooking up for sex, and when we couldn't do that anymore, it was pretty much already over."

I was stunned to hear that admission. I was still a virgin, though admittedly not by choice.

"Oh," I said. I squirmed a bit. "What does that have to do with me?" I asked.

Natalie spoke up then. "KJ, you know that none of us have treated you right over the years. We have all been talking about that the past few weeks, and I just wanted to say that we are all really sorry. Seriously, we were really immature, and we feel bad."

She saw that I was suspicious as she said that, and she sighed. She got up from the chair, then, and walked right up to me. She reached out and took my hand, pulling me to my feet. I'm not sure what I expected to happen, but I was completely unprepared for what did happen. Natalie—impossibly hot, sexy-as-fuck, stroke fantasy for every guy at my school Natalie—wrapped her arms around me and started kissing me! My eyes shot open, and I was just standing there in shock.

I was so surprised I didn't even think to kiss her back. Natalie looked really sad as she pulled away from me. Katie spoke up.

"I was afraid that wouldn't work," she said to Natalie. Natalie just nodded, and a tear ran down her cheek. I looked from my sister to her friend, and I was just befuddled.

"I..." I couldn't even figure out what to say. I had no idea what was going on. Normally in that situation, I just lose my temper and yell. I sat back down.

"What is going on?" I said softly.

"Natalie wanted to ask you out on a date," Katie said to me.

"Really?" I said. I looked at Natalie and asked, "Why would you want to date me? You don't even like me. Is it a pity date because you feel bad for me?"

They looked at each other, and they looked surprised.

Natalie spoke up. "Is that what you think? You really don't get it, KJ. I wanted to ask you out because I think you are hot."

I snorted at that, but then saw that Katie was nodding in agreement. I narrowed my eyes at them, sure they were playing some cruel, drawn-out prank. Katie stood up, then. She shrugged at Natalie before she turned back to me. She smiled and leaned over to give me a peck on the lips. "I'm sorry, too, KJ," she whispered.

She had never, ever kissed me before. I was half expecting it when she walked to my door and opened it before yelling, "...and if I ever catch you getting into my stuff again, I'll kick your ass!" She smiled at me again and then slammed my door closed. Natalie got up and locked it behind her.

I was completely floored when she turned to me and then started undressing as she approached. Natalie's breasts were absolutely amazing, and they were right in my face. Setup or not, there was no way I was going to let this opportunity pass me by. I eagerly sucked on her nipple, and took both her breasts in my hands to feel and softly squeeze them. Natalie moaned softly as I sucked her breasts. She whispered to me.

"KJ, scoot back on the bed."

I did, after hesitating to release her breast. Natalie was still wearing her lacy white panties, and sexy little white ankle socks. She crawled over me on the bed, sitting on my lap and leaning over me to feed me her hard nipple. Since I was a little taller than she was, she slid up to give me her breast. I could feel her hot pussy right on my belly button. She moaned softly again as I sucked on her nipple. When I slurped on it a little loudly she quietly shushed me.

I felt her little hand reach behind her and feel my hard cock in my shorts. Her fingers traced up and down it for a bit and then she whispered, "May I?"

"Mm-hmm," I moaned around her nipple. I didn't know what she was asking permission for until I felt her unzipping my shorts and reaching inside them. She fondled my dick through my underwear and then I saw her looking down at me.

"I really am sorry for being so mean to you," she whispered softly.

"I really do want to date you," she added after a slight pause.

She pulled her nipple from my mouth and leaned down to kiss me again. This time, I did kiss her back. I slid my tongue into her mouth and she sucked on it and ran her tongue around mine. She slid onto her side next to me on the bed, and reached down to squeeze my dick again while still kissing me. I played with her left breast.

She broke off the kiss and looked into my eyes. "That was really nice," she murmured.

She sighed then, and looked down as she pulled the waistband of my underwear up and looked at my hard dick for the first time. "Oh, KJ, that is one really nice dick. I wish we had more time," she almost purred as she said it.

I was just dumbfounded when she slid down and sucked the head into her hot mouth. That just felt amazing. It was the first time anyone ever had their mouth on my dick, and I loved every second of the experience. Unfortunately, we were cut off in less than a minute. We heard my sister's voice approaching.

"I'll get him," she hollered down the hall.

That was apparently Natalie's cue. She whispered, "Sorry!" as she hopped from my bed and pulled her shirt back on. She unlocked the door, letting Katie open it and say "Time for dinner, KJ!" She was standing just outside my bedroom, and her head was facing the kitchen when she said it. I was hastily pulling my shorts back up and zipping them, and Natalie was getting dressed.Katie smiled at us, and I had to smile back.

"You jerk!" she said to me, still smiling.

"Seriously, you need to learn how to knock!" I spat back, also still smiling. I gave Natalie a hug. She dashed into the bathroom that was across the hall from my bedroom while Katie and I headed to the dining room. Natalie emerged from the bathroom a few minutes later and said goodbye to Katie and my mom. She ignored me completely until she winked from the front door and left.

Smoking-hot Natalie wanted to date me. That was a freaking bombshell I did NOT see coming.

I have to admit, the thought kept me up that night. I was wide awake in my bed, stroking a boner that would not go away. I was surprised to hear a light tapping on my bedroom door. Since Katie never knocked, I assumed it was my mom. I tried to hide my erection by pushing it down the leg of my underwear and then bunching the covers over my crotch.

"Come in," I said.

The door opened silently, and Katie stepped into my room. The house was really dark, so I could barely see her after she closed the door behind her. She couldn't see very well either. I picked up my cell phone and tapped it so we had a little light. I pointed it toward the wall behind me so it wasn't too much.

I could see Katie then, standing by my bed in a thin t-shirt. I saw her nipples through the shirt, and that surprised me. I couldn't ever recall seeing her without a bra, except when she was wearing a swimsuit.

She whispered something, but I couldn't understand her. She cleared her throat and shook her head, and started again.

"Sorry," she whispered, "I wanted to talk to you, if that's alright."

"Sure," I whispered back.

For once, it didn't feel like a trap. My sister looked nervous, even a little uncomfortable standing there. I slid back toward the wall, to give her room to sit down on my bed. She looked relieved at that, but then she slid under the covers next to me. My bed is narrow, so she was lying right next to me. I didn't want to start a fight with her by saying something stupid, but I was worried about poking her with my hard dick.

The light from my phone lit her face, just inches from mine. She looked into my eyes thoughtfully, but then the light from the phone went out.

"Should I turn on a lamp or something?" I whispered to her.

"Probably not," she whispered back, "If Mom or Dad get up, they would see it and they might check to see why you're still up."

"Okay," I replied. That did make sense, but it would take a few minutes before my eyes would adjust to the dark enough to see Katie's face at all.

I could feel her warm body pressed against mine, though. In the dark like that, she just felt soft and amazing against me. I mean, I know she's my sister and nothing was going to happen, but my hard dick couldn't make that distinction. Katie's breasts were pressed against me, mashed into the right side of my chest. I could clearly feel where her nipples were poking through her shirt.

"You smell good," Katie whispered. I could smell her toothpaste on her breath, since our faces were inches apart. At that moment, I was glad I had showered. I almost never get up early enough in the morning to shower before school, so I usually shower before bed. Katie's shampooed hair always smells good.

"Thanks," I said, "so do you."

She leaned her body into mine, resting the side of her face on my shoulder. Her arm wrapped around my waist and she was lightly rubbing my back. Her right leg sort of wrapped around my left thigh. She just sighed and lay there for a while. It did feel really nice, even if I was frozen in place. I didn't know what to do or say, so I just lay still and didn't say anything.

She sighed again before she asked me, "KJ, do you hate me?"

"Yup," I replied, "Not so much right now, but...come on, Katie, we have never liked each other."

"Yeah," she said sadly.

We lay there quietly for a while again. I could just barely make out her silhouette against the lighter wall behind her. I really wanted to see her face right then.

"Hold on," I whispered to her, "I have an idea."

I reached up and found the pull cord for the Venetian blinds in my window. I slid my hand over until I found the rod that adjusted those blinds and turned it until they let moonlight stream in toward the ceiling. It wasn't a lot of light, but compared to the pitch black we had been lying in it was a dramatic difference. I could clearly see Katie's expression now. That face is what I picture now every time I see the word 'wistful.'

"What's wrong?" I asked her.

A sad sort of smile spread across her whole face, but gradually. Katie looked...wow, my sister looked beautiful when she smiled like that.

"Oh, KJ, so much is wrong...I'm not even sure where to start." Katie's eyes were searching mine as she continued. "I have been thinking about us, all these fights over the years. It seems like such a waste now. We could have been friends if we weren't so busy fighting."

I didn't know about that. I don't think Katie and I ever had that much in the way of common interests, outside of hating each others' guts.

"Now, when I look at you," she went on, "I see this incredibly good-looking guy. All my friends—yes, those same friends who treated you like shit for years—saw you walk in to school this year and were just blown away. We all feel like complete assholes now. Of course, then we were talking about it...Tanya brought up that we have also been really shallow, because we wouldn't even have noticed how rotten we've been if you hadn't turned into such a hottie. That just made us all feel worse, because of course she was right."

"My friends never have those kinds of talks," I said. Katie looked at me questioningly and I explained. "You guys can't be that shallow, because none of my friends even have that kind of deep conversation."

Katie smiled at that, not the sad smile from earlier, but a genuinely amused smile. "That wouldn't have occurred to me," she said.

I finally felt relaxed enough to put my own arm around her and gently rubbed her back as she had been doing to mine. I felt her tense back muscles slowly relax beneath my fingertips.

Katie groaned softly at my touch. I could feel that groan, against my shoulder as her warm breath washed over it and also against my chest and abdomen as her chest heaved out that breath. Katie mumbled then.

"And the other problem is that you are my brother, of course."

That one confused me. "Why is that such a problem?" I asked.

She looked into my eyes again, and could tell I really didn't get it.

"I'm not sure I should tell you this..." she whispered it softly. There was a long pause as she made up her mind. "Look, you're my brother. If you weren't, though, I would be all over you right now. I haven't been laid in almost a month, and I'm horny as hell."

I could feel the heat from her panties, pressed against my hip. I had to chuckle softly at that one, though.

"I've definitely got you beat there," I whispered back, "I haven't been laid in eighteen years."

Katie pulled her head back and looked at me shocked. "Really?" she whispered a little louder.

I just nodded sadly.

"Wow, I had no idea," she lay her head back on my shoulder, "I just figured you were getting laid at summer camp, same as me and my friends."

I looked at her in horror before it dawned on me. "Wait," I got out, "There were guys at your summer camp?"

"Yeah," she said. Her eyes shot open then. "There weren't any girls at your summer camp? Oh my god, I had no idea."

We both just lay there as that reality of the past six years sunk in. That really explained a lot, for both of us. It also made me imagine just how different my summers could have been.

Katie's thigh finally brushed against my erection, and she froze.

"Sorry," she whispered. "Is that your dick?"

I couldn't help it. "Nah," I whispered, "I always stash a little summer sausage in there in case I get hungry in the middle of the night."

"Shhh!" she whispered, although she was the one who was laughing. Her thigh rubbed deliciously against the bulge in my underwear.

"You are so bad," she whispered. I was grinning as I looked at her smiling face. Then she caught me completely off-guard again. She leaned up and started kissing me.

Really kissing me, like I had never been kissed before. Katie gave me an education in passionate kissing over the next fifteen minutes. It took me the first three just to try to get my head together and kiss her back, but then it just got better and better. When we finally stopped, we were both trying to keep quiet as we caught our breath.

Katie was trembling through her whole body. I could feel it the length of my body.

"Are you okay?" I asked her softly.

"No, not at all," she bit her lip, looking like she might cry. "God, KJ, I want you so bad right now."

"But I'm your..." I didn't get to finish.

She rolled her body out of my bed as she said, "I know."

I got a really good view of her bottom. Her shirt had ridden up in the back. Her panties were practically a thong in the back, just a slender string separating her gorgeous ass cheeks. I sucked in a sharp breath at that amazing sight. She heard me.

Katie stopped in her tracks and looked over her shoulder at me, then followed my gaze and realized it was glued to her sexy backside.

"I'm sorry, Katie," I mumbled when I realized she had caught me looking.

"It's okay, KJ," she whispered back. "Do you think I have a nice ass?"

"It's amazing," I replied honestly. I was still looking at it. "I had no idea you had such a sexy ass."

It dawned on me who I was talking to at that moment, and I felt my face blush. "Sorry!" I whispered again.

I expected her to be mad. I half expected her to yell at me, or throw something. At the very least, I figured she would cover her bottom and storm out of my room. She did cover her bottom with the hem of her shirt, but she smiled at me and said, "Thanks," softly before she quietly left my room.

I lay there stunned for a good four minutes. I could not believe that just happened. Then I heard another soft tap on my door. "Come in?" I whispered.

Katie genuinely looked embarrassed as she came back in and once again closed the door behind her.

"Sorry, KJ," she whispered. She came back over and slid back into my bed, "I got so distracted that I forgot to say what I really came here to say in the first place."

We both smiled at that.

"I talked to Natalie on the phone after dinner. She was so turned on, telling me how sexy you were."

I felt my cock lurch at that. So did Katie. She moaned softly as she felt it press into her thigh. I was pleasantly surprised when she reached down and softly squeezed the middle of the shaft.

"Damn," she whispered, "It's nice and thick, too." I saw her lick her lips as her fingers lightly traced their way down to the base of my shaft and then all the way up to the tip. I was hard as granite and all I could do was lie there and breathe heavily.

She didn't say anything either. Her fingers squeezed the head of my cock and then worked their way around it. They then retraced their way back down to my balls and she lightly squeezed them as well. Her breathing was getting heavier as her fingers worked their way back up to the tip of my straining dick.

I finally found my voice. "Katie, if you don't stop that, I'm going to come." She groaned at that and she lightly bit my shoulder.

"Oh, KJ, you should not have said that," she whispered. Her hand slid inside the waistband of my underwear, and she started stroking my hard cock. "That was just mean," she whispered again, "teasing your sister with this hard cock, and then telling me you're going to come."

I didn't think I was being mean. I thought I was just giving her fair warning. I really needed to learn the rules of this game.

"I was just trying to warn you," I said. I thought my voice sounded a little whiny, so I cleared my throat softly before I continued in a deeper, quiet voice. "I didn't think you would want me to shoot a big load of cum all over your hand."

I could see her eyes light up. Her nostrils flared at that, and she growled at me. I was unaware that my sister could be such a hungry animal. You should never tease a hungry animal. It's a dangerous and foolish thing to do.

In my case, I found that I was soon feeding that hungry animal. My sister slid beneath the covers and just slurped my cock right into her mouth. I nearly cried out loud at the sensation, but managed to bite my lip and suck in air through my nose instead. She was unbelievable, taking half my cock into her mouth and applying gentle suction. Her tongue felt incredible as it was all over the head of my dick. I don't think I lasted two minutes.

"Coming!" I managed to gasp out, just as the first shot erupted from me. It would not have been enough warning for her to stop, but Katie had no intention of stopping. I felt her moan in her throat as she gulped down my sperm. It was way too intense for me. I blacked out, briefly. It couldn't have been that long, as I was still coming in my sister's mouth when I could see again.

I was still shaking with the aftershocks of that unreal orgasm when Katie released me from her mouth and slid back up my body. She gulped the last of my cum down her throat and then said, "Thank you. I really needed that."

I couldn't believe that she was thanking me. "Really?" I gasped out, trying to keep my voice down, "I can't believe you're thanking me. That was fucking amazing. Thank you!"

She just smiled at that, actually looking a little shy and embarrassed. I realized, though, that she was still stroking my cock. My underwear was pulled down to just below my balls and it was uncomfortable.

"I'll just get those out of your way, if you don't mind," I said. When I reached down for my waistband and lifted my hips, she understood what I meant and she leaned back a bit to give me room. I slid my underwear down to my ankles and pushed them off beneath the covers. I lay back down, and moaned softly as her hand immediately found my cock again.

"You're still hard," Katie chuckled softly. "Natalie is in for a real treat."

I had to chuckle at that. Katie's eyebrows raised in question.

"Please don't tell Natalie, but I had completely forgotten we were talking about her," I said.

"Yeah," Katie said, looking down at my now exposed cock, "I'm not sure she'd be that understanding if I told her I had been sucking your dick. I mean, she'd understand, but it's still incest."

My erection throbbed in her hand when she said that. She couldn't help but notice. Katie looked like she was going to say something naughty, but then bit her lip and shook her head instead. She gently let me slip from her grasp, and pulled the sheet back over us.

"Let's see, where was I?" she was whispering again. "Oh, right. Natalie really wants to get some time alone with you. But, with that rule our parents laid down, we couldn't figure out how to make that happen. She could come over here, but Mom's always here. You and I could go over to her place, but her mom is also always around. Natalie suggested we could go out on a double date, but that still doesn't give us a place where we would have any privacy. She said I should ask you. Any ideas?"

Nothing sprang to mind.

"Not during the week," I said as I thought it over. I had my right arm under Katie. I brought it to her back and began gently scratching her back as I lay there and thought some more. I was looking up at the ceiling, but I could see her looking at my face out of the corner of my eye.

"On a Saturday, if Dad isn't home, she could come over here if you went out with Mom somewhere. Maybe..." I looked at her then, "Any chance you and Bryan could get back together? We could go to his place."

She pulled a face at that. "I don't think I want to try getting back with him, now," she said, "Bryan was a total dickhead when we couldn't have sex anymore. I realized then that sex was really all we had going on, and it wasn't even that good."

Ouch.

"Is there anyone else you are interested in?" I asked then. She looked a little embarrassed.

"Not really," she said, "I have been a little too preoccupied with you, lately."

"Oh," I whispered back. I didn't know what else to say on that topic.

Katie reluctantly disengaged from my arm and got out of my bed. She looked really sexy bathed in the moonlight. I realized for the first time that my sister was every bit as hot as her friends. That shook me up a bit. I had been hard all evening thinking about Natalie, but my dick was throbbing under the sheet as I checked out my sister.

"I'm in no hurry to have Natalie take your virginity," Katie whispered, "So we can just think it over until we come up with something."

"Okay," I responded. I realized that she was leaving, so I got out of my bed and spread my arms to offer her a hug. She just stood there and stared at my hard dick for a good minute, so I felt really awkward.

"I was going to hug you goodnight," I grumbled. She smiled at that and stepped into my embrace. I hugged her as best I could, trying not to squeeze her too tightly.

"You are so hard," she mumbled into my chest.

"Sorry," I whispered back.

We released each other and I whispered, "Sweet dreams, Katie."

She was looking at my hard dick and licking her lips. She finally shook her head and looked back up at my face.

"You too."

I stood there and listened to her soft footsteps fade down the hallway. I lay back down and figured it would take me a while to fall asleep. I had a lot on my mind and I was still rock hard. I was also drained and tired, though. I fell asleep almost immediately.

For once, I got right out of bed when my alarm went off the next morning. I had neglected to put my underwear back on, so I searched around under the covers until I found them and tossed them into my laundry basket. I got dressed for school like a robot, all without thought. I was thinking about Katie, about how amazing her mouth felt on me, and about Natalie.

A loud pounding at my door made me jump.

Katie pushed my door open and lit into me. "There! I knocked! Happy, now?"

I cocked my head, looking at her and wondering what she was doing. She raised her eyebrows at me, as if we were in a play and I had forgotten my line. I realized then that we essentially were putting on a production for our parents' sake.

"Wow. You actually learned how to knock on a door," I had found my sardonic voice. "Let's give Katie a freaking Nobel Prize for figuring out how people in civilized countries have been doing it for fifteen hundred years. What the hell do you want from me, Katie?"

"Nice," she whispered, before raising her voice again, "There's just no reasoning with you, KJ! Seriously, I just came to see if your lazy ass was out of bed, and you give me crap!"

"Keep it down in there!" Dad's voice carried down the hallway.

Katie smiled and gave me a big hug. I hugged her back, loving the way her body felt in my arms.

"We're on our own for breakfast," she said softly. I nodded as I released her.

We made a real show of ignoring each other as we ate breakfast. We actually talked in the car, turning off the radio as we rode to school. We sat in the car and kept the conversation going until Annette walked up to the car. We got out, then. I smiled at Annette.

"Good morning, Annette," I said to her, "You are looking lovely today."

She actually blushed at that. "Thanks, KJ," she said softly.

"You two have a great day," I said, "I'll see you this afternoon."

At lunch, I had the weirdest confrontation in the cafeteria. I was approached by Coach Harper and Coach McMahon, the football and wrestling coaches at our school. They looked annoyed with me, and I honestly had no idea why. I knew who they were, but was really surprised they had any inkling who I was."Why didn't you try out for the team?" Coach Harper said. It was blunt, and it was how the conversation started.

"What do you mean, Coach?" I had never played competitive football. I had always been too small. I didn't have the first clue about wrestling, other than knowing it was a very technical sport.

"You are one of the most athletic kids at the school now, and you didn't even try out for the football team," he continued.

"Or the wrestling team," Coach McMahon chimed in.

"I'm sorry," I said, "I was a summer camp counselor. I was in another state when you held tryouts. To be honest, I have never been that good and it never even crossed my mind."

They just looked pissed as they shook their heads and walked away. I was still getting over the fact they even knew who I was. Then I realized—they probably don't know who I am. They never addressed me by name or anything like that. They just saw a fit-looking tall kid who wasn't in either of their programs and felt compelled to confront me about it.

I shook my head and got in line to grab lunch.

I was headed to the table I normally shared with my friends, five guys I had known for years, when I noticed there wasn't an open spot at the table. That sometimes happened. I looked around for a place to sit, and spotted an open seat. It was between two of my sisters' friends, Sarah and Carol.

I felt a little bold, so I walked up and asked softly, "May I join you for lunch?" All nine of them looked at me wide-eyed, but Sarah managed to say, "Sure."

"Thanks," I said to her as I sat down beside her. "Oh, Sarah, I meant to thank you for that shirt you got me for my birthday. It is really nice."

It was nice, an authentic Sean John shirt. Not one of the 'ghetto fabulous' trashy-looking ones, this was a sharp dress shirt. I had worn it to school once already.

The look she gave me...wow, I almost got shivers. "You're welcome," she said breathily, "I'm glad you like it."

I looked around the table, and these girls were all looking at me. I kept my voice low and said, "You should probably talk to each other. People are starting to stare."

They all looked around them. It was comical how everyone who had been looking our way suddenly looked startled and became very interested in their food. I grinned and tried not to laugh.

"Are we really that bad?" Carol whispered from my left.

"Nope," I replied to her. "But you could totally take advantage of that killer rep you guys have if you ever want to."

They all looked intrigued at that idea, and then they really did start to have some interesting discussions among themselves. I have to admit, our cafeteria did have some really good food. I enjoyed it almost as much as the company that afternoon. I approached my friend Jeremy after lunch.

"Hey, bro. I wasn't ditching you guys at lunch today. I didn't see a seat at our normal table, so I sat with my sister and her friends. I hope you don't mind."

Jeremy just looked at me like he couldn't believe I was saying what I was saying. "Dude, I wish I was as ballsy as you," he finally said. "If I could get away with sitting with the Nine, I would totally do that."

I hadn't ever heard them called that before. Probably because one of the Nine was my sister. I got the reference, though, and bit back a laugh. It did hit me, then, that my sister was easily one of the hottest women in our school. She had been in my bed last night. She had sucked me off. I should NOT have thought about that at that moment. I had to hide a boner the remainder of the school day.

My pants were still embarrassingly lumpy as I held my backpack in front of me and waited by my sister's car after school. Katie and all eight of her friends came walking out of the school. They were walking in step. I don't think they realized they were even doing it. It looked both cool and intimidating at the same time. If I had filmed it and replayed it in slow motion, it would have fit right into a music video.

They split up into smaller groups as they reached the parking lot. Katie and Natalie came right over to me.

"Hey," I said, "How was your day?"

"Good," they replied, not quite in unison. They looked around then. "Did you think of a plan?" Katie asked.

I shook my head. "I'm afraid not, and believe me, I have really been thinking about it."

Natalie looked like she wanted to eat me up right there in the parking lot.

I leaned in to her and kissed her softly on her neck. "I can't wait," I whispered into her ear.

She just shivered. I felt so awesome in that moment. Like I had just discovered I had some mutant superpower. Natalie went to her car, and when I slid into the passenger seat of my sister's car I realized she looked jealous. I am pretty sure she was unaware of it. I looked over at Natalie and waved, but talked to my sister.

"Katie," I said softly to her, "I'm not trying to be mean. You should know you have a really jealous look on your face right now. That could be bad for us if your friends see it."

She gasped, and looked into the rearview mirror, adjusting it with her right hand. I slid my hand over and squeezed her right thigh gently. I was still looking out the windshield.

"Don't worry, I can't wait to give you a kiss on your sexy neck," I said.

"Me neither," she whispered back.

No one was around when we pulled up to the curb at our house, so I leaned over and planted that kiss on her neck. Katie groaned when she reached her hand over and felt how hard I was.

It was a brief kiss and grope, and then we went into the house. Once again, we made a show of ignoring each other. I took over the dining room table and got busy with my homework. It took me almost two hours to get it all done, easily the most homework I had ever had in one day my entire life. Mom was really impressed. None of Katie's friends came over that day. Mom asked Katie about it, and I overheard.

Katie delivered an excellent performance. "Everyone is over at Sarah's house today. They're watching a movie, and I really wanted to see it, but my brother"—she spat that out—"refused to go over there with me. He acted like he had all this homework to get done, but obviously he just doesn't want me to see my friends or have any social life."

I looked over at my mom and just rolled my eyes. She had seen me actually doing all that homework.

"Katie, you could have asked me—" she started to say. She stopped, then, when she realized that she couldn't give Katie permission to go anywhere without me until she talked with Dad about it first. She looked really frustrated at that. "Let me call your father," she said finally.

"Mom," Katie blew out an annoyed huff of breath, "It's too late now. I'm sure I missed half the movie already."

"Just let me talk to him. You kids have been punished enough," Mom said.

Poor Dad, I thought as I put away my books. He has no idea what he is in for this evening. I smiled a little wickedly at the thought.

Sure enough, right after dinner my mom dragged Dad off to their room. Katie and I both heard her say, "We need to talk," before she closed their door. Katie and I exchanged raised eyebrows as we cleared the table. Normally we take turns doing the dishes, but that evening we both did them, straining to hear how our parents' conversation went.

It wasn't that great, from the sound of it. Mom was using her reasonable, patient voice on Dad. He felt backed into a corner and got pissed off. He started yelling at her about the time we finished rinsing the dishes and loaded them into the dishwasher. We heard mom drop her ultimate weapon, then.

She started crying. I kissed Katie on her neck again, and headed to my bathroom to shower. After my shower, I saw a light coming from under Katie's doorway, and one small lamp on in the living room. I went to my room and got on my computer. Katie's bedroom was right across the hall from my parents' room. She sent me a text an hour or so later.

"Dad just spent a half hour apologizing to mom. Think they're having sex now."

"We still restricted?" I responded.

"Don't know," she sent back.

A bit later, Dad came to my door. His voice was gruff. "You and Katie can go out, on your own, but you need to let your mother know where you are going. Be back by midnight."

"Okay," I nodded. Katie got the same message. I could barely hear him through my open door.

Katie came to my room again that night. I had left the door slightly ajar for her, and the blinds were where I had left them the previous night. I heard her light footsteps before she came in. Katie closed my door softly. I heard her lock it behind her.

Katie slid into my bed again, and I slid over to make room for her.

"You do realize," Katie said, "We just manipulated the hell out of Mom and Dad."

"It sounds like it worked out, though," I responded, "Dad basically handed the reigns over to Mom. You know she'll be reasonable."

"Right," Katie whispered. "If it makes you feel any better, Dad made it up to her, for making her cry. I could hear him eating her pussy for like a half hour."

I looked at her face a little sharply as she said that. Her eyes had a dreamy look. I could only compare it to the experience I had of getting my cock sucked. That simple act had made up for years of heartache in my case.

I think I had started to really change as a person as a result of actually doing all my homework. I was really seeing the benefits of studying—my grades were better than they had ever been, and I was never at a loss in class anymore. I felt like this was another subject I really ought to try studying.

"Katie, I want you to do me a favor, if you don't mind," I said softly.

"What's that?" she asked.

"I need you to teach me how to eat a woman's pussy," I said, "I mean really do a good job of it. I've never done it, and I think it's something I need to learn."

She couldn't pass up the opportunity to be a smart ass. "Whoa, hold on there, KJ. Are you suggesting I know how to eat a woman's pussy?"

"Nope," I replied. We were both smiling. "I need you to let me lick and suck your pussy, and tell me how to do a better job of it. I may need lots and lots of practice. I want to be really good when you decide to unleash me on one of your unsuspecting friends."

"So you think I'm just going to turn you loose on all my friends? Is that your fantasy, you perv?"

Now, she said that, but she was sitting up in my bed and scooting her butt up toward the headboard. I rolled over her left leg and onto my stomach. Katie was able to raise her knees slightly and spread her legs. I found her neatly trimmed little bush right in front of my face. She had come to my room wearing only a t-shirt.

I really didn't know what to do.

Katie started me off with the basics. She spread her lips open and pointed out the little bud at the top.

"This is the clitoris. If you don't know how to do anything else, just lick this over and over."

I leaned forward and gave it a tentative lick. Katie shivered at that. I continued softly licking it, but Katie apparently thought I was doing it too softly. She grabbed the back of my head and really pulled my face into her crotch, hard. My nose got mooshed into her little patch of pubic hair, and it actually hurt a bit.

I pulled back and whispered, "Ow! What the heck, Katie?"

"Oh! I was almost there!" she hissed back at me.

I figured she just wanted me to lick harder, so I reached my hands behind her and seized her pliant butt cheeks, pulling her firmly into my tongue. I really licked her clitoris hard, then. I was looking at her face, and her eyes shot open wide. She leaned her head back and started to moan out loud, then bit her lip to keep the sound in.

I slid my tongue inside her a little and then lapped up over her clitoris. I loved the taste of her juices that I got that way, so I kept doing that for a while. Katie's thighs squeezed against my ears, making it difficult for me to continue. I was pulling her toward my face by her ass cheeks, and she felt like she was trying to push away from me. I was starting to get frustrated, feeling like she was intentionally making it more challenging for me.

I hissed out, "Ow!" when she yanked my hair, pulling me forcefully away from her.

"Dammit!" she hissed at me, "I said 'stop!' I'm so sensitive right now, you jerk!"

"I couldn't hear you; you had your thighs covering my ears and you were crushing my head!" I hissed back.

"Oh," she whispered then, releasing my hair, "Sorry. I had no idea I was doing that."

I sat up and rubbed the back of my head until it didn't hurt as much. Finally I whispered to her, "So, how did I mess that up?"

My pulse had been pounding in my ears from her thighs crushing them, so I was just starting to hear normally. Katie laughed softly. She had apparently been gasping for breath for a while.

"That was fucking amazing," she finally whispered to me. "It was maybe a little too intense for me, really. I didn't realize you couldn't hear me. You made me come at least three times. After that last one, I was so sensitive it hurt."

"Oh," I said. "So next time, what should I do differently?"

She started to laugh, then bit off the sound when she saw my expression. "Seriously?" she whispered.

I nodded.

Katie looked thoughtful, then. She also looked a little uncomfortable with her legs still spread open around me like that. We were a little awkward as we moved around until we were lying facing each other again. She giggled a little, softly.

"You have got my juice all over your mouth," Katie whispered to me, "You probably need to wash that off before..." Her voice trailed off as I licked her juices from around my mouth.

Of course, then my saliva was all around my mouth, so I wiped it off with my hand.

"Did I get it?" I whispered.

She nodded. "Damn, you have a really long tongue," she whispered again.

I couldn't help it. I giggled. "The better to eat you with, my dear," I tried to whisper my best Big Bad Wolf impersonation. She laughed softly and pushed my shoulder.

"You're such a dork!" she finally whispered through her smile.

"So, how can I do better next time?" I asked again.

Katie kissed me softly and then started getting out of my bed. "I'll tell you next time," she whispered.

"Good night," I whispered to her.

"Good night," she whispered back as she softly unlocked and opened my door.

After she was gone, I masturbated to a thundering orgasm. I was thinking about my sister the whole time.

The next morning, in the car, Katie said, "KJ, you have got to stop looking at me like that. Seriously, it's a little creepy."

"What do you mean?" I asked. I really didn't know.

"You have that whole love-struck puppy thing going on. I'm your sister, remember? The one you can't stand. You really need to get that look back, or everyone's going to think we're fucking."

"Alright, I'll try to do that," I responded. I narrowed my eyes at her and turned up the corners of my mouth in a disapproving sneer. "Better?" I asked.

She snorted a little laugh when she glanced over at me. "Better, but still not great," she said. "You really suck at this."

I guess I had a hurt expression when she said that. She glanced over and said, "Much better."

I thought to myself, my sister may be sexy as hell, but she really is a bitch.

I kept that in mind, and it sustained me through the day. I passed on sitting with the Nine at lunch, since Jeremy had saved me a seat. My friends were always there for me. Nobody mentioned or asked about yesterday's lunch. We chatted idly about classes and girls while we stuffed our faces. Shawn told a really funny joke, and Seth shot a little milk out of his nose as a result. It was a good lunch.

When I got up to empty my tray and put it in the stack, Natalie was right in front of me in line. It was a quick minute, but I got to admire her shapely ass the whole time. I felt like a dork when I realized that Katie and half her friends saw me staring that whole minute. I was going to catch some hell after school, I thought.

I did, but it wasn't the sort of hell I imagined. I waited at Katie's car for an awfully long time after school let out. Two thirds of the cars were gone from the parking lot when the Nine emerged, once again in lockstep. They were all looking at me as they approached. I shifted uncomfortably. I had been standing there for at least fifteen minutes, and my new shoes were killing my feet. Those girls looked like they were on a mission. They were headed right at me.

They marched up and stopped, fanning out so that I was surrounded. Natalie walked right up to me. Her face was a little flushed.

"I heard you were staring at my ass in the cafeteria," she said. I nodded, not knowing what else to do.

"KJ, everyone saw you staring at my ass. That is just so disrespectful." She wasn't loud. She didn't sound all that angry, but she did sound serious. "We were trying to figure out how to punish you for it. We had some ideas, but those were a little kinky."

As she said that, her eyes darted over to Sarah. She colored a little at that. My mind was all over the place, but the one thought that really stood out was, "Sarah is the kinky one? I never would have guessed that."

Natalie cleared her throat, and all the girls closed in behind her, forming an impenetrable semicircle around the two of us.

"You need to apologize, KJ," Natalie said. Her eyes had this weird expression that I just could not read. I couldn't tell if she was mad, turned on, embarrassed, or what.

"Hey, Natalie, I'm really sorry," I said. "I had no idea I was embarrassing you like that."

"No," she said, "You need to get down on your knees and apologize like you really mean it."

I was going to protest, but her hand on my shoulder was insistent. I figured I would just do it and get this over with. I went to my knees in front of her. Before I could say a word, though, she pulled my face right into the crotch of her tight shorts and said softly, "Kiss it."

I could smell her arousal through her shorts. I surprised all of them. I set my backpack aside, reaching behind Natalie to seize her shapely ass as I planted a loud smooch on her zipper. I squeezed her cheeks, and every one of those girls could see me do it. I pulled my face back, then.

"This was a really bad idea, Natalie," I said. My voice was not loud, but they could all hear me. "If I really kiss you down there, the best I can, your panties and shorts will be completely soaked. Wouldn't that be more embarrassing than me staring at your sexy ass?"

All nine of them gasped at that. I did plant another soft kiss at the junction of her thighs. "I am sorry that I disrespected you," I said, looking up into her smoldering eyes, "I won't do it again. Forgive me?"

She growled at me, once again looking like she wanted to eat me up on the spot, but my sister spoke up. "I think that will do for now. Get up, KJ."

As they dispersed, I had never seen those girls look so shaky. I got up and picked up my bag. As soon as we were in the car, Katie was just staring at me. She had that same tough-to-read expression that I had seen on Natalie's face a couple minutes before.

"What the fuck was that?" she breathed.

"What?" I said, "I told her I was sorry."

"Yeah, right!" she went on, "And now every one of my friends is thinking about my brother eating their pussies."

"How do you know that?" I countered.

"Because that's what I'm thinking, and I could see their faces! Was that your plan all along?"

I looked at her and shook my head. "I didn't plan anything, Katie. I'm not going to bullshit you—I always thought your friends were hot. I also knew every one of them is out of my league. What I have just figured out here lately, though, is that my sister is hotter than all of her friends."Katie just looked at me for a long minute. She shook her head and started the car. Halfway home she said, "I am going to suck your cock so hard tonight."

It was really tough for me to concentrate on my homework after that. Katie called me a dork and a space hog, getting me to limit my stuff to half of the dining room table. She spread her own work on the opposite side. We bitched at each other for a little while, until my mom called out from her room.

"Keep it down in there, you two! I can't hear my show."

I grumbled, but my heart wasn't in it. Katie had taken off her shoes, and her toes were sneaking up the leg of my shorts. I wasn't really a toe guy, but she had really good control as her toes stroked my hard shaft. I found out that Katie was skilled at multitasking. She finished her homework within twenty minutes and left me at the table. It took me another half hour to finish my work.

Katie left to hang out at Carol's house, but she was back in time for dinner. My dad was pleased that she was prompt getting back to the house. I really did try to ignore her for the rest of the evening, mostly because I didn't trust my control over my expressions.

I was halfway through doing the dishes when Katie approached me and whispered, "What are you doing?"

I looked at her, not sure what her point was. "It's my night to do the dishes," she said. I felt like an idiot as I looked over at the little chart on the front of the fridge. She was right. That is not a mistake I ever would have made prior to the last couple weeks. I set the glass back into the sink softly and dried my hands, trying not to draw attention as I joined our parents in the living room.

It took Katie less than five minutes to finish the dishes. When she plopped down on the couch next to me, Dad said, "That was quick." He turned up the volume on the television to drown out the dishwasher.

I wasn't all that interested in the show that was on, so I excused myself and went to my room. I played on my computer, wishing for the millionth time that it didn't have parental controls. I couldn't watch porn, and couldn't even delete my browser history. This was a few years back, so I was probably playing one of those massive time-sucking games like Civilization or something.

Whatever it was, I got really into it for the rest of the evening. My mom knocked on my door and reminded me to grab a shower. I turned off the computer, gave her a hug, and washed my body. I was practically shaking in anticipation when Katie finally came to my room an hour later. She was quiet as she locked the door behind her, then she pulled her shirt off over her head and hung it over the back of my chair.

Katie looked just unbelievable. Naked, her body was so perfectly proportioned that she looked like a centerfold. She pulled back my covers, and was surprised to see I was wearing my underpants.

"Do me a favor, KJ," she whispered, "from now on, you need to sleep naked."

My voice cracked a little as I hurried to take the offending drawers off. "Okay," I croaked.

She was on my cock like a starving woman after that. She slurped a massive load out of me and kept right on going. Granted, I was so horny the first one took all of five or six minutes, if that. I lasted a lot longer after that, though. It felt absolutely unbelievable. She had to remind me to be quiet four times. When I was getting close to coming a second time, she had to stop.

"My jaw is starting to really hurt," she whispered apologetically. My hard dick was pulsing and bucking against my belly. I had been really close.

I carefully got out of the bed. "You lie down here, Katie. It's my turn to do you."

She took my spot, and I knelt between her thighs. She spread her legs for me, and I put them up over my shoulders. I kissed her puffy lips tenderly.

"So, what tips do you have for me tonight?" I asked, "How can I do it better than last time?"

She had apparently given it some real thought. She answered immediately. "You need to pay closer attention so you know when I'm coming," she said, "My pussy will be really sensitive—especially my clit—right after I come. When that happens, you need to stop licking there and sort of softly tease the rest of my pussy until I'm ready for you to do it again. Does that make sense?"

"Yes. It will help if you let me know when you're getting close, and when you actually come. Okay?" She nodded, and I started licking her clit.

"Too hard!" she gasped immediately. I nodded and licked her softly. After a minute of that, she hissed, "I'm getting close. Don't stop, just keep licking it just like that."

Her thighs started closing in on the sides of my head again, so I reached up and tapped the insight of her right thigh softly with my left hand. She nodded down at me and forced her legs back open.

"Coming now," she moaned softly. I could feel her wetness on my chin and her legs shaking. I eased off of licking her clit and languidly worked my tongue around her lips. I was curious to see what would happen, so I started sliding my tongue into her opening. She bucked in shock at that, "Christ! I'm coming again!"

I had to pull my mouth away. "Shhh," I reminded her. It was distracting, seeing her magnificent breasts bouncing all over as she came. I slid a finger inside her to replace my tongue as I savored the taste of her in my mouth. My finger was really able to gauge more accurately how her orgasm was going. I withdrew it when she was obviously done with her climax and, I presumed, too sensitive.

She was panting and trying to catch her breath. She looked so sexy. I slid up her body and whispered, "May I?" as my mouth closed on her right nipple.

"Yes!" she whispered.

I realized that night that my sister had her most intense orgasms when I sucked on her clit and buried two wet fingers inside her pussy. I hadn't yet figured out how to feel for her 'g-spot,' but when I occasionally brushed it, she had a really tough time keeping quiet. Since she was letting me know each time she came, it was easy to keep track. Seven times she came from my mouth and fingers that night.

She did suck another load from my cock before she left my room. We both overslept the next morning.

Mom was actually in my room after turning my bedroom light on. "KJ! Get up! You and your sister need to get going or you'll be late for school!"

I shot out of bed, only realizing when I saw my mom's shocked expression that I still wasn't wearing underpants. I grabbed my pillow and covered my crotch, gasping out, "Sorry, Mom!"

Great, I thought, not only did she see me naked, but I've got morning wood, too. Mom's got to think I'm some kind of pervert now.

I did get dressed quickly, and had time to scarf down a power bar and a cup of milk with vitamins before Katie was dressed and ready to go. I handed her a power bar with vitamins, and carried a plastic cup of milk to the car for her. We both hollered out, "Bye, Mom!" before we closed the front door behind us.

We made it to school and into class before the tardy bell rang, but it was really close. As I sat in my first-period English class, I realized we had to be more careful with these late-night exploits. Much more careful, if we didn't want to get busted. After school, Katie actually brought it up first as we sat in her car in the parking lot.

"That was just way too close this morning," she said as soon as we were alone in the car.

"It was worse than you think," I said, "Mom saw me naked, and I had a hard-on."

"Really?" Katie laughed at that. She shook her head, but kept laughing, "Sorry, KJ, it's just—good lord, I can only imagine her face."

I shook my head and looked out the window. There were still a bunch of cars in the parking lot. Football and band practice were both right after school, and there were other after school activities, so it wasn't like we were the only car in the lot. I turned and looked at Katie.

"Do you think I need to talk to Mom about it?" I asked.

"About what? Her seeing you naked this morning?"

"Yeah."

Katie looked thoughtful as she started the car. "I would let her bring it up, if I were you."

"Hold on, don't leave yet," I said. Katie turned off the engine.

"What's up?" she asked.

"We really need to get a plan together. We'll get busted for sure if we just keep going like we have been."

It took a good forty-five minutes before we got a text from my mom. "Everything OK?"

I thought quickly. We had both got the same text. "Let me call her, I have an idea," I said. Katie nodded as I called Mom back.

"Sorry about that, Mom," I said, "It was totally my fault, Katie was stuck waiting for me. I'll explain when we get home. See you soon. Love you!"

I filled Katie in on the story as we drove home. She made sure she looked pissed as we walked in the front door. As she stomped off to her room, I said, "I said I was sorry! It wasn't even my fault!"

"Whatever!" she said as she slammed her door.

"What happened?" my mom asked.

"It was so weird, Mom," I said, "I got cornered by Coach Harper and Coach McMahon, and they were grilling me about why I hadn't tried out for football or wrestling this year."

This was a true story, but obviously that had happened a couple days earlier, at lunch. I went on.

"I don't even think they know who I am, really. They just see me now, after that growth spurt, and I look like one of the guys that should be on their team. Anyway, I told them that I was working this summer at the camp when they held tryouts."

Mom had glanced at my crotch when I mentioned 'growth spurt.' It was subtle, but I caught it. I think I managed to keep that out of my face. I finished by apologizing to her again for making us late, but she was dismissive.

"That's okay, KJ," she said. "Clearly that wasn't anybody's fault."

I nodded gratefully. "Thanks for being so understanding, Mom," I said, as I started getting to my homework.

After dinner, Katie went to hang out with her friends. Jeremy and Sean came over after I called them, and we had a nice time hanging out like we used to. According to plan, Katie did not come into my room that night. I didn't sleep well, but I did get enough sleep that I was up when my alarm went off.

In the car on the way to school, I said, "I know it was my idea, but I still missed you last night."

"I missed you too," she said.

I was thinking about Katie's gorgeous naked body. That was a mistake, as it made me hard instantly. She saw my annoyed expression out of the corner of her eye.

"What's wrong?" she asked.

"Dammit, I started thinking about your sexy body and now I'm all hard," I whined. "I'm going to have to hide this all day."

Katie snickered a bit. "Sorry," she said, but she was giggling. I didn't believe her.

I did manage to will my erection away before English class was done. At lunch, I wound up getting there earlier than my friends, and I grabbed our usual table. I heard a soft voice behind me say, "Hey."

I turned around and saw Carol standing behind me. "Hey, Carol," I said, "How are you?"

She was holding her tray flat against her body, since she hadn't gotten food yet. She looked a little shy or embarrassed. "I'm having my eighteenth birthday next weekend," she said, "I wanted to invite you. Katie said it was okay."

"I would love to come to your birthday party," I said. "What should I get you for a present?"

Carol involuntarily glanced down and then looked embarrassed. "You don't have to get me anything, KJ. I'd just like you to come."

"Okay," I said, not wanting to embarrass her further. "Thank you for inviting me."

She moved along to get her lunch, and my friends started arriving right after that.

Our table was mostly full when Jeremy asked, "So, what did Carol want?"

I couldn't pass up the opportunity. "Oh, you know, she wanted me to meet her after school and bend her over for a..." I didn't even have to finish that. Everybody just lost it.

I grinned, "She was letting me know I could tag along with my sister to her birthday party. As long as I get her something nice."

Sean whined at that. "Man, why don't hot chicks invite me to their birthday parties?"

Doug said, "Because you don't have a smoking hot sister."

I glared at him for that one. He just spread his hands. "What? Dude, she may be a bitch, but your sister is hot."

I blew out a breath. "You have no idea," I said, "She's secretly an evil little gnome who climbs into this hot chick outfit before she leaves her room."

They all busted up again at that one. It was the first time I realized that my best friends all lusted after my sister, though. I couldn't blame them.

It was Friday, but I still got right on my homework after school and knocked it out. Katie and I both got permission and went out with our friends. I went to the movies with a couple of my friends.

Late that night, Katie was naked in my bed again. While I licked her tasty pussy, she told me that Natalie seemed a little desperate to figure out a plan for us.

"Oh, that's really good. Right there," she gasped softly. I leaned back after she finished coming, licking my lips clean. "Where was I?" she continued, "Oh, right. Natalie said her parents may be out of the house Tuesday night. Her aunt invited them for some family thing, but since it's a school night, Natalie would not be able to go with them. The problem is, her parents won't leave until after nine, and that doesn't leave a lot of time before we'd have to be back here."

I listened to her. It sounded to me like Natalie and I would still have at least two hours together in that scenario. Katie didn't look happy about even telling me this. I wondered if she even realized she was jealous of Natalie spending time with me. I rested my head on the inside of her thigh and softly ran my index finger around her puffy pussy.

"Did you tell Natalie that I was a virgin?" I asked her softly.

"No," she whispered back.

"Good," I whispered as I slid up to kiss her. She moaned softly as my tongue invaded her eager mouth. I was becoming a much better kisser under her tutelage. Her eyes opened wide when she felt my hard cock entering her pussy. I pulled my mouth from hers and whispered, "I'd hate to make you a liar."

"But I'm your sister!" she moaned softly.

"I know," I whispered back.

Her pussy felt absolutely wonderful as I slowly slid deeper. She was so wet that I had no trouble sliding my full length inside her, even though she was so tight around me. When I was all the way in, I held still. I kissed her gently on her mouth.

"Should we stop?" I asked.

"Yes," she breathed back, "We should definitely stop."

Her legs wrapped around my back.

"But we won't," she finished.

As was usually the case, my sister was right. That night, I didn't mind just how deeply and thoroughly correct she was. I knew Katie was on the pill, and at her urging I filled her pussy with a massive load of cum. Twice.

Saturday morning I slept in blissfully. I was not in a hurry to leave the bathroom after I got out of bed. I could not keep that silly fucking grin off my face. I really didn't know how I was going to face my parents or my sister without looking like I had done exactly what I had. I had gotten laid. It was far better than I had even imagined it would be.

I was spared when I heard my mother holler from the front door.

"We're leaving now. We should be back in time for dinner. Call us before you go anywhere!"

"Okay!" I yelled back.

I waited until I heard the car leave before I finally left the bathroom. I had showered and brushed my teeth. From the opposite side of the house, Katie emerged from the other bathroom she shared with our parents. She was wrapped in a bath towel. She grinned at me.

"So, KJ, do you have any plans for today?" she asked.

"I really didn't," I answered. I was being honest. Oh, sure, I could call my friends and find something to do. I had a feeling that wasn't going to happen.

Katie really enjoyed riding me on the living room couch. I was really able to savor her fantastic tits while she was able to control the angle and depth of my cock inside her. I was getting better at figuring out when she was close, and then I was able to drag it out to give her more intense orgasms.

My personal favorite was taking her from behind, playing with her gorgeous ass while I watched my dick sliding in and out of her snug pussy. Her expression when she looked back over her shoulder at me was impossibly sexy. I came really hard inside her once that way. I was able to hold back my next orgasm for hours.

Some of the positions we tried were just not all that great for either of us. By noon, Katie was just done. I still hadn't had that second orgasm and she lay in her bed and groaned when she saw how hard I was.

"KJ, I have to stop," she said as she slapped my hands away from her. "Seriously, if you slide that thick dick into my pussy any more today, I will be sore for a week. Stop!"

I relented, but my eager dick was still waving around over my thighs. She rolled away and pulled on fresh panties and shorts. She reached for her phone and made a call, putting on her shirt as she waited for an answer.

"Who are you calling?" I figured she was leaving the house, and was calling Mom.

"Reinforcements," she replied.

You know how I said earlier I wanted to fuck every one of her friends, but that would never happen? Turns out I was wrong.
