For the past year I was terrified that I was a major pervert. Then, I started reading these letters, and found out there were other people out there just like me. I knew I had to write my own letter.

My story starts a year ago, when I was a 16 year old sophomore in High School. I was a pretty average kid in most ways, but one thing I was pretty much an expert at was jerking off. I loved jerking off, and had done it about five times a day since I was 13. I was also an expert a not getting caught. My mother and sister, who is two years younger than me, had no clue at all how dedicated I was to my favorite pass time. I absolutely mean my favorite passtime. Whenever I was alone in the house, I would jerk off, immediately.

Originally I would just jerk off while picturing a hot girl in my head. Gradually I discovered that it was a lot more fun if I had a girl to look at, in a magazine, on the computer, or on TV. Then, I got to the point where the most exciting thing to look at was a real live girl. This was not a huge problem for me because my sister Julie has a lot of friends, and we have a swimming pool in our yard. The window in my room looks right down to the pool area. With my trusty binoculars and a jar of petroleum jelly I could have fun for hours. At the beginning, my favorites were Julie's friends Ashley and Courtney. Ashley is a tiny cute blonde, who's tits are developing faster than the other girls. Because she is so small, and always wears a string bikini, her tits would attract my binoculars a lot, especially when they would get wet. Her nipples easily show through the thin material of her suit. It makes me want to cum just describing her. Courtney's best attribute is her amazing ass. She has long legs and a "apple bottom". She usually wears a one piece suit that looks like it was bought last year and she has outgrown it. The suit is constantly riding up her ass, especially when she climbs up the ladder in the pool, which conveniently is positioned perfectly for my viewing pleasure. I have lost it many times, and shot a load at the precise moment that Courtney reaches the last step and slowly reaches around to pry out the material that has disappeared up her ass crack! Equally sperm inspiring is the sight of Ashley inserting her thumbs into the edges of her bikini top and loosening the vacuum grip that her wet top has on her lovely tits and nipples.

For my sister Julies 14th bithday we had a big pool party. I was very excited about the prospect of checking out some new talent from my favorite vantage point. In an amazing stroke of luck, my mother had borrowed a digital video recorder with a "zoom" feature, and put ME in charge of it. I made sure I got of reasonable amount of footage in the house and on ground level, then got that puppy up to my room and popped in a fresh tape. I was frustrated that I couldn't jerk off well while operating tha camera, so I stopped trying. I figured I would have a good time later, especially with the "slow motion" and "pause" features. I was having a good time filming the girls, with long pans up and down their sexy legs, zooming in on tits and asses, and adding my own little play by play. Then, I caught an amazing view of some fresh talent. I panned over to the ladder and caught the most amazing sight climbing out of the pool, "What a gorgeous ass" I quetly announced out loud. She was in a green bikini and I couldn't recall seeing her yet, she must have just arrived. As she continued up the ladder I saw the most amazing set of legs, shimmering and flexing, that I had ever seen in our pool. I couldn't stand it, and fumbled for my cock as I attempted to steady the camera on my eye. As she stould up and turned to her right I slowly panned up to her tits and exclaimed, "Oh my god, her tits are nicer than, Ashley's!" I was already rock hard, and had no time to look for lube, so I just spit in my hand and started jerking. As I was doing this, I was able to keep the camera on her tits as they genly jiggled up and down when she jogged to the diving board. To mount the diving board she had to turn those tits toward me, and as she did I felt an increased flow of blood to my cock and a a lovely twitch as I leaked out some pre-cum. Her tummy was just as delicious and I zoomed in while panning down a little to her pussy just as she raised her leg to climb onto the board. "Oh my god you're hot!", I said as I started to feel that familiar churning in my balls. She walked out onto the edge of the board and raised her hands in the air, which raised raised her tits and emphasized her lovely rib cage. I heard my sister yell, "watch this dive!" Everyone else must be watching this girl just like me, I thought, as she started to gently bounce up and down on the end of the board. Her bouncing tits and my strokes on my cock fell into time together just as my climax began, and I announced to the camera, "I'm going to cum!" As she lofted into the air, I screamed in pleasure, and at the precise moment she hit the water a huge stream of my cum hit the window directly in the phrame of the camera. I slowly squeezed out the remainder of my sperm as my new favorite girl slowly swam underwater back to the ladder. As she climed up the ladder, I put down the camera and grabbed my set of binoculars so I could get the best view of her face. She reached the top level and turned, I leaned foreward in anticipation. There, standing triumphantly, smiling in her new green bikini, was my 14 year old sister, Julie. "How was that for a dive!", She yelled to no one in particular.

The whole night I tossed and turned with hardly any sleep. I was trying to understand how this could happen. I had never looked at my sister that way before. I would always focus on her friend's, but not her. If she was the only one swimming I never even went to the window, but now! That god damned new green bathing suit, if she was wearing her old one I would have known it was her immediately. But Jesus! When did her tits get so big! That seemed to catch me by surprise. And her ass! There was no doubt about it. My sister Julie had a better set of tits than Ashley, a better ass than Courtney, and one of the best sets of legs I had ever seen in my life! Oh Christ! My cock was getting hard thinking about her! I briefly thought about trying to make my hard cock go away, or start thinking about something else, but I couldn't. This time I jerked of a fantastic orgasm while envisioning my sister's body, and KNOWING it was my sister's body. Then, I finally fell asleep.

As I slowly woke up the next morning it hit me that it was Sunday. Sundays are awesome because my mother goes and works out at ten, stops at my grandmothers for a visit, and then goes grocery shopping. Julie and I used to have to go along, but a couple of years ago we talked my Mom into letting us stay home for the day. It was a great chance to have some free time. I rolled over and looked at the clock, which said 10:50. I was sure Julie had a couple of friends sleep over, but the house sounded quiet. As I sat up and rubbed my eyes, a bolt of panic shot through me. The camera was gone! It was on my dresser when I went to bed, and it was gone! I immediately found myself jogging to the stairs as I was wondering what I did with the two tapes. The tape of the party was in the camera case, and the tape of Julie was IN THE CAMERA! As I flew down the stairs I saw Julie watching TV. She was watching the tape of the party, NOT the tape of her. "Hi", I said. "Hi yourself", Julie said, as she continued to watch. "It was an awesome party, Sis!", I said. "I'm really glad you enjoyed yourself!", Julie said. She didn't usually talk like that, did she know something? I still didn't want to overplay my hand, so I slowed down and kept talking. "Where did your friend's go?", I asked. "They got picked up about 20 minutes ago", she answered. "Have you been watching the tape long?", I asked as I picked up the camera case and looked through it. "I haven't seen much of it", she said, "I had a chance to see all of this one, though." She said as she held up the other tape. "Oh my gosh, Julie, I'm so sorry", I said, "please forgive me and don't tell Mom!" She looked me right in the eyes and then began a slow sly smile. "To tell you the truth, Kevin, It made me feel really good, so don't worry about my feelings", she said. I was shocked. "It made you feel good?", I ased in disbelief. "Kevin, you said I had a gorgeous ass, nicer tits than Ashley's, told me I was way hot, and I made you cum", Julie said, "that was probably the best birthday present any boy could have given me." This is not what I was expecting, all I could do was sit down on the couch and stare at the TV in silence.

The tape ended and, before I realized what was happening, Julie had the other tape back in the TV. Julie was intently watching the tape, with her legs resting on the coffee table, and her bare foot flirtatiously shaking. I found my attention directed there rather than the TV. How pretty her feet were, her toes still flawlessly painted from her preparation the day before. Then, as my eyes traled up past her ankles to her shapely calves I found myself appreciating all those soccer practices she had to go to over the past few years. I continued my journey up past her kness to her thighs, just as I heard myself on the video saying, "oh my god you're hot!" My cock was now alive, and rapidly finding its fullest possible shape in my shorts. Then, just as I heard myself say, "I'm going to cum!", Julie whipped her legs off the coffee table, crossed them tightly in her lap and began rocking quickly back and forth. She seemed to jump a little bit just as I heard the splach into the water, and I knew what she was looking at. The tape abruptly ended and Julie turned and looked at me. Her face was very flushed, and I knew she was as excited as I was.

The next moment was one that was going to change both of our lives forever. "Kevin, do you want to see me bare naked?", she said. "Hell yeah!", was all I could muster. "OK, come on", she said as she bounded up to her room. I was right behind her, so close I could have tagged her. "Sit on my bed", she said as she stould in front of me. "Here's the deal, I'll get bare naked for you if you let me watch you jerk off!", she proposed. This was hardly something I had to think about. I answered by pulling off the only article of clothing I was wearing, a pair of gym shorts. As I did, my fully erect cock stould up at attention. "Oh my god, Kevin, I've never seen one before", said Julie, as she crouched and leaned forward to inspect it. I slowly started to rub it up and down and her eyes widened. "Does it feel good?", she asked. "Yeah", I said, "It will feel even better if you get naked!" She smiled and immediately peeled off her clothes. How could I have been oblivious to how gorgeous my sister was until yesterday. She probably had tits as big and full as any girl in my grade, and this was the first time I had ever seen a pair of real live nipples. Her pussy was very pretty and pink with small whisps of finely cropped hair. Her legs were slightly parted, and I could make out the unmistakable sheen of wetness on the bottom of her vulva. I was hypnotized by her body, until my sisters voice broke the silence. "Kevin, can I try it?", she said, as she watched me jerk my cock. "If you let me suck on your tits", I bargained. She walked toward me and I had the delicious sensation of my hands pressing into the tender flesh of my sister's tits as she simultaneously wrapped her fingers around my cock. She wanted to stare at what she was doing, but I had to break hear gaze and lift her head so I could get my mouth around her nipple. I tenderly began sucking on my sister's tit, which caused my cock to throb in her hands. "Holy cow, Kevin, that feels amazing!", she praised. We continued for a few minutes with me alternating from one tit to the other and her softly milking my cock. Intermitantly, my cock would ooze out some pre-cum, which she would rub with her thumb and spread around. "Don't guys put something on it so it slides easier?", Julie asked. "Yeah, you can spit on it!", I replied. Julie said, "Gross!", but her eyes twinkled and she smiled. She unceremoniously bent down and sprayed a mouth full of saliva on my twitching cock. When she started stroking again the improved traction, along with the knowledge that it came from my first "girl spit" made my body swim in pleasure. She was now on her knees stroking my cock, so I began running my hands through her hair. "julie, will you try something for me?", I asked. "I know what you want", she responded, as she slowly placed the tip of my cock in her mouth and began sucking. She continued to suck the tip off my cock, as she jerked the rest of it with two hands. What I fool I had been, I thought jerking off was so good that it actually kept me satisfied and away from persuing real live girls. My sister's inexperienced workings of my cock were vastly superior to anything I could ever do for myself. I wanted to give her the same feeling.

"Julie, lie down on the bed", I suggested. She stopped sucking and looked up at me, "we can't DO IT, Kevin, that would be incest, but this is just fooling around", and she returned to sucking my cock. "I wasn't going to try to DO IT with you, Julie, I just wanted to do for you the same thing you are doing for me." Julie stopped sucking again and hopped up onto the bed, "Oh, OK!" She was on her back with her legs spread and a big smile on her face. I had never done this before, but I had a pretty good idea of what to do, and slowly leaned in. I didn't hesitate, I went right for her slit and gave it a big long lick. "OH MY GOD, KEVIN!", came bellowing out of Julies mouth. This obvious sign of pleasure, combined with the amazement of having more of her juices in my mouth than my own saliva, inspred me to several more repetitions. "OH GOD, OH MY GOD, OH KEVIN, OH CHRIST!", Julie couldn't keep her mouth shut! I was thinking I must be pretty good at this, as I stopped for a second to avoid drowning. I looked up from my target, along my sister's belly, between her heaving tits, just as she lifted her head to look at me. "Oh my god Kevin, we're going to have to do this again", she said. My cock was in need of some attention again and I had an idea. "Hey sis, your pussy is real wet and I want to see what it feels like, if I promise not to put it inside, can I rub my cock on the area I was licking?" "That's a wicked good idea" she said. I climed up on the bed and took a position between my sisters legs that put me on the steps to hell, but I didn't care. I took my hard cock in my hand and slowly began rubbing it up and down my sister's soaking wet pussy. "OOOo, Kev, that feels even better than your tongue", Julie said ad she deliberately wrapped her legs around mine and began pulling on my thighs with her calves to the pace of my strokes. The velvety feeling was even beyound my imagination. I looked down at my sister's sweet face and had an overwhelming desire to kiss her. I wrapped my arms around her to brace myself, looked into her eyes, and leaned in for a full and tender open mouthed kiss. We both began to passionately moan and closed our eyes. No sooner had they closed, than we both opened our eyes with the realization that my cock was now about two inches inside of her pussy. I looked her in the eyes and said, "Sorry" in a way that she knew meant I would now pull my cock out. ""Oh Kevin, this feels so nice, just stay there for awhile and kiss me." We both closed our eyes and kissed again, but our bodies had minds of their own. We were both gently grinding with each kiss, and my cock was pressing into her further and further. "Just don't cum inside me OK, Kev?", she hoarsly whispered. "OK, Julie", I grunted back. We were passsionately, but carefully, getting closer by the inch when we both felt her barrier. We did't say a word, we just looked at eachother and kept up the same pace. I swear, as I looked deeply into her eyes, I fealt her hymen gently stretch before it suddenly gave way. I saw her wince in pain, and then immediately flush with pleasure as my cock impaled her and I felt my balls press into her ass crack. The pleasure this brought me was intense, and it caused me to quicken my pace. Julie was right there with me, and I could feel her finger nails dig into my ass as she began pulling me into her. "Oh, Oh, Kevin; Oh, Oh, Kevin!", she was chanting a little anthem for me. My balls were starting to boil and I knew in about ten more strokes I would be filling her pussy with a dangerous brew. "Julie, I've got to pull out now", I warned. She looked at me deliriously and moaned, "DON'T, DON'T YOU, DARE, STOP!" Just then I heard the front door swing open, "kids, I'm home, come down and help with the groceries!" Julie looked at me with the most determined animalistic look I've ever seen, "don't, you, stop, Keven, I, I'm", and then her voice raised, "GIVE IT TO ME KEVIN, GIVE IT TO ME!" She was screaming, and I was five strokes away from blast off. "Kevin, whatever your sister wants you better give it to her!", Mom shouted up to me. Julie bit into my shoulder and let out a low gutteral moan and I could feel her pussy spasming around my cock, "BUT MOM!", I screamed. "No buts, give it to her!", Mom ordered. As if on command from my mother, I took two more strokes and shuddered as my cock emptied stream upon stream of sperm into my sisters womb. Having no shoulder to bite on, I screamed in pleasure. My mother took my screams as a realization of defeat and praised me from the kitchen, "that's a good big brother, Kevin!" Julie looked up at me in shock, and then started giggling, which caused her body to milk the remaining drops of cum from my cock. I fell onto her in total satisfaction, and she playfully ran her hands through my hair and teased, "that's a good big brother."
