My name is Jake, and I’m a twenty-three-year-old bloke. My younger sister, Lexi, just turned eighteen, and I have to tell you about what happened one summer day.
Our father is from a Chinese background and our mum is from Australia, so both Lexi and I have a mid-dark complexion. Lexi is about five foot seven, with curly black hair, very smooth skin, and an athletic body. Just recently, she has grown into a beautiful 32 C, which has quickly come to my attention.
Lexi and I were very close as kids, being only a year apart and the only two children. We used to do everything together. We were both involved in a lot of sports like swimming and football, so we kept quite competitive and fit.
My parents and I were supposed to go visit my grandma for the day, leaving Lexi at home by herself. But just before my parents picked me up from football, I decided I wasn’t really in the mood to go. So my parents dropped me back home and left. I walked through the front door, and the house was quiet. I couldn’t see or hear Lexi, so I assumed she had gone out to see her friends.
As I walked out the back, I saw Lexi lying on a pool chair, sunbathing. To my astonishment and delight, she was topless! She seemed to be resting with her eyes closed, and it was a beautiful sight. I had thought about my sister many times before, but I had never seen her half-naked. I just stood there, staring at her goddess-like body, a cow to an oncoming train. I pertinently scanned her entire physique, making sure she wasn’t awakening.
Her legs were smooth and freshly waxed, and her golden skin glowed in the sun, assisted by what must have been some body lotion. The only thing preventing her from complete nakedness was her tiny red bikini bottom, which her tight, round ass was desperately seeking to escape. Her flat stomach contrasted immediately with her large, round breasts, which she had grown during puberty. I could tell they hadn’t seen much sun by their slight paleness. Each perfect breast slightly parted outward, resting on her slender arms. Her nipples were larger than I had imagined, protruding about half an inch.
As I continued to search her body with my sinful eyes, I delighted in her curly black hair, still wet from a previous swim. Her hair draped across her chest, hugging the curves of her large, natural boobs. The sight was magnificent. Even though she was my sister, I couldn’t deny she was the most beautiful girl I had ever seen.
After seeing my hot sister half-naked, I was getting quite aroused, and my cock rapidly grew in my thin football shorts. I thought I better leave, just in case she woke up and saw me with a massive eight-and-a-half-inch erection. I felt like taking a photo, she was so damn hot. If only my parents hadn’t taken the camera. So I decided to head back inside, so I didn’t embarrass my little sister and myself. I was so excited from the fact that my sister was half-naked and was still in awe of how beautiful she was. I decided I needed to cool down from my football game and got ready to go for a swim next to where my sister was. So I put on my speedos and noticed my cock was still half-solid, about seven inches long and quite thick, as it had to curl up in my tight speedos.
I started to head back outside, thinking about how I would approach the situation and wake her up. To my relief, she had already gotten up and was standing there, drying her hair with her towel. Her tits were flying and bouncing side to side as she swayed her body. When she stopped, she saw me, and I stopped as well, pretending to be completely surprised. She made no effort to cover her boobs and instead, converted her surprise into asking me why I was home. I said I changed my mind. As I spoke, I made my best effort to look up from her perfect breasts and into her eyes.
After I explained, she accepted it and said, “I didn’t know you were coming home, so I thought I could sunbathe without anyone seeing me.”
I said, “Don’t worry about it, you know I don’t care. Do you want to go for a swim with me, sis?”
She seemed to let it pass and gave me a big smile, saying in her sweet voice, “Sure!”
She ran over to where her bikini top was hanging and put it on, and I got a good eyeful of her boobs bouncing around.
Just as she tied the knot on her bikini top, I ran up to her, picked her up with one arm under her legs and one under her back. She screamed, then laughed as I ran with her and jumped into the pool. She giggled and playfully pushed me down under the water by my shoulders. As she came down, her boobs passed down my chest. In retaliation, I swam back up to her and bear-hugged her. My big arms tightly wrapped around her body, her boobs squashed against my chest. I wrapped my legs around her ass, causing the bulge in my tight speedos to force into her red bikini bottom. I used every limb to hug Lexi, and there is no doubt she felt my large dick press into her pussy.
There was nothing weird about it, as I was just getting her back from dunking me. We were both having so much fun. We were both laughing and giggling as we innocently wrestled. I was loving it so much, feeling every part of her body. It seemed like Lexi was enjoying it as well, as I could see her large nipples were getting hard, pressing through her red bikini top. I was so turned on from touching her and seeing her boobs.
After I bear-hugged her, she tried to swim away, laughing uncontrollably as I swam after her. I grabbed her by her ankles and dragged her back. When I had full control, I decided to return the favor and playfully dunked her under the water right in front of me. As I pushed her down by her head, her face scrolled into the ever-increasing bulge in my speedos. Wow! She practically just touched my cock with her face, I thought. That was awesome!
By now, I was so horny and turned on from playing with my eighteen-year-old sister, my dick was fully erect and like steel. I noticed this as she passed by my package and decided I should probably stop and conceal my massive erection, so I started to swim away.
She said, “There is no way you are going to dunk me without getting payback!”
She swam after me, probably quite aware by now that I had a giant cock. Due to my exhaustion, Lexi caught up and, to stop me from getting further away, grabbed my speedos from my ass as I was swimming away. I continued, and as I did, my swimmers slid right off me and down my legs into Lexi’s hands. My cock flung right out, like a spring, and was throbbing as it stood there as stiff and large as ever.
To my surprise, my sister just stopped, holding my speedos, and stared at my giant cock. There was no way I could hide it. As she stared, it felt like time had frozen. I looked back and noticed her nipples were rock hard. As she breathed heavily, her large jugs would rise and fall, suspended only by her red bikini top, which she must have owned before she had developed breasts, as they were obviously a size or two too small for her.
After she’d gotten a good look, time started ticking again, and she started laughing hysterically.
“Haha, what are you going to do now, Mr. Erection?” she said.
What was originally embarrassment and shame turned into arousal, particularly due to the fact that my little sister was intrigued and excited that we were sexually flaunting ourselves to each other. I soon realized that my sister had no shame at all and was having the time of her life.
From that, I mouthed to her, “You are going down…” I gave her a wry smile and instantly jumped and swam after her.
She squealed and started to swim off, still holding my speedos. Just as she was about to jump out, I had caught up and enveloped her from behind. My long arms reached around her torso, just under her boobs. As I did this, my hard eight-and-a-half-inch cock punched itself between her thighs. She tightened her legs as the top of my dick met the underside of her bikini bottom, and my pubic region slapped onto her round and firm butt cheeks. I playfully twisted and shook, attempting to grab my speedos from her, although I didn’t really want to get them back.
As I twisted, my dick, still lodged between her thighs, pulled out and pushed back in as I lunged with my hands to get the speedos from her firm grip. As my hands fell from lunging, my right hand landed on top of Lexi’s right breast. My hand impulsively ripped off her bikini top, causing her right tit to burst into full view. As she rotated to get it back, I noticed she was trying to grab her bikini top while still laughing, while I was trying to get my speedos back.
She didn’t seem to care that my enormous penis was poking into her pussy mound. Had she not worn the thin red bikini bottom, my cock would have surely gone straight in. Lexi was stretching out over me to get her bikini back. In doing this, her right boob slid along and up my chest, going as far as my face. Her boob completely smothered my face, and it was the best feeling I had ever had. The nub of her hard nipple flickered along my sensitive skin. Her pale, wet breast was so soft, so untouched. Her virgin body was lathering itself upon me as I used her bikini to lure her over me.
Meanwhile, Lexi was not in a state of anger or embarrassment but was rather laughing and enjoying the competitive challenge of getting one another’s clothes.
My cock was so hard it was beyond belief. It continued to pound and press into Lexi’s lower region as she persistently roped herself onto me. I couldn’t take much more. I was so sexually aroused and excited I was about to ejaculate and probably pass out and drown.
So with my final ounces of power, I leaned back into Lexi and put my arms around her waist. The time we connected this time was different. We weren’t laughing. We were in each other’s arms, I being naked and she nearly there. It was completely silent, other than the slapping of the water. We looked each other in the eyes, exploring each other’s feelings. I could tell she wanted me by the way she looked at me with her innocent, hazel eyes.
I leaned in to kiss her. She remained completely still as she received the innocent peck on the lips. We both paused again. I was afraid she might have just treated this as a game and that she would negate the kiss.
We remained still…
Until she smiled, leaned back into me, lifted her hands up around my broad shoulders, and kissed me right back. Right then, I knew she wanted me! The hottest girl I had ever seen wanted me! She was my sister, but I was so aroused by what we’d just been doing that I would happily go to hell for eternity as long as I could have my way with my sister.
As she leaned in to kiss me, I met her halfway, and this kiss was more passionate because we both knew that we wanted each other. We pushed aside the prejudices that a brother and sister should not relate sexually. We were both lovestruck. She tilted her head sideways, allowing our mouths to connect and our tongues to meet for the first time. We both had our eyes closed as we exchanged fluids. My arms explored her back, then her sides. I no longer felt cautious. We both had come this far. We both wanted each other so much.
I then moved my hands down to her holy ass. It truly was an amazing thing. Her butt cheeks perfectly filled out her red bikini. They were perfectly round and bubble-like. As my hands trekked to this un-ventured part of her body, I squeezed her ass, and Lexi responded in turn.
While still kissing me, Lexi removed her hands from around my neck and immediately found my still bulging cock. She used both of her small hands to circumnavigate the girth of my penis. She then broke free of the kiss and led me to the large step in the pool by tugging on my cock.
When we reached the step, only six inches deep in water, she laid me on my back and examined my cock some more, considering she hadn’t really seen one before. I watched as she knelt down and started using both hands to jerk me off. Her little hands couldn’t even wrap around my penis. She slowly gave me a hand job as she slid her hands up and down my long, thick shaft. I was in heaven. My foreskin rolled up and down as the water lubricated her movements.
After about six minutes, Lexi got up and walked over and sat on my chest, facing my pulsing dick. Just having her ass touch me was so nice, even though it was still hidden underneath her red bikini bottom. After sitting on me, she leaned forward, holding my cock, and put her lips over the head of my penis. She started to kiss it, and then her virgin lips slid down. She could barely fit it in her tiny mouth and could only manage to handle about two inches of it. It was amazing, having my sister’s mouth envelop my cock. While she was doing this, her ass was right in front of my eyes. It was a glorious sight. I decided to use my hands to remove the barrier preventing Lexi from being naked. I slowly pulled down her red bikini bottom while she was sucking me off. Her bare, smooth legs were straddling either side of me.
I finally slid her red bikini bottom off her legs, and I almost came from the sight of her juicy ass. I couldn’t see her pussy, but I could feel it on my chest. Every time Lexi thrust down, I could feel her smooth, shaven, eighteen-year-old pussy lips slap my chest. It was so warm, and I could feel her vaginal juices dripping out and running down onto my stomach, where Lexi’s heavy boobs would keep slapping.
I was so close to exploding, but I desperately wanted to explore the pussy I had dreamed about all these years. I started rubbing Lexi’s clit with my palm as she devoured my cock. Her legs started quivering, and I could tell she was enjoying it. She started to breathe heavier and moan softly in an innocent, high-pitched voice. I had taken control of Lexi. She told me to finger her, so I slipped two fingers into her tight cunt. I began to slowly pump my fingers in and out as torrents of fluid came dribbling over my hand. She started trembling and moaning very loud, and I started to laugh at how much she was enjoying it.
With myself on the peak of exploding, I told Lexi I wanted to fuck her. The new vibrancy of Lexi that I had never seen before was unleashed, and she stood up, turned around, facing me, gave me a devilish smile, while holding my massive cock in her hands. She gave me a look as if to say, I want you so bad, but I don’t know if I can take your cock.
With that, she slowly lowered her virgin pussy onto my steel rod in the missionary position. She only got as far as the head of my penis spreading her pussy lips before she squealed in pain. She jumped back up. I realized that this was not the best position for her first time. So I got up. I got her to lie face down on the step with her legs together. I knelt down around her legs and placed my cock between her thighs, my cock being as big as Lexi’s entire forearm. I slowly entered her from behind, having to force my monster between her legs and between her pussy lips. She was so tight; this was no easy task. I began forcing my cock in very hard so it would slide in. I finally got a couple of inches in her. Her ass presided above the water line, as the water flowed over it. It was so sexy. I leaned forward and began to fondle Lexi’s large, natural boobs. I was tweaking her nipples while progressively working my way into her pussy. I began to squash her boobs back into her as my body made full contact with hers. My penis was about four inches in before I reached her unbroken hymen. With a quick, hard thrust, it broke, and Lexi gave a sharp squeal, and a tear rolled down her sweet cheek.
But she was overridden with pleasure as I now began to drive my cock in further. Six, seven, eight inches. She was screaming and moaning. My balls lapped up against her firm ass cheeks and my entire cock was buried in her tight, virgin pussy. She was clearly in pain, but I knew at the same time she was experiencing so much pleasure. I started to thrust in and out. It felt so good. While she was moaning with pleasure, she managed to scream out, “Fuck me hard, baby, your cock feels so good in me. I’ve never felt this way before. I’m gonna cum.”
At this point, I was delirious with arousal, and my balls were ready to be drained. I started pumping into her furiously. The sound of my balls slapping against her hot ass was so sexy. I couldn’t believe she was taking my whole cock in her pussy. I started to grunt and moan. I was about to cum all over my sister, and it felt so good. I kept pumping in and out of her tight, virgin pussy. Madly, I forced myself into her; she was screaming with every thrust.
I yelled to her, “I’m going to cum!”
So I pulled my wet cock out from her pussy, turned her around, and exploded all over her tits. Massive streams of cum flew from my cock onto my sister’s large breasts. The amount of semen I blasted surprised myself. Now she was rubbing herself and managed to orgasm at the same time. She was squealing and moaning while my endless, thick cum shot out rapidly all over Lexi’s face as well.
I collapsed on top of her, completely exhausted. My cock just rested on her stomach as we held each other for minutes. She eventually gave me a smile and told me that that was the greatest thing that had ever happened to her. As she began to lick my cum off her own tits, she assured me that that would not be the last time we were going to do this.
