My name is Alex, and I am 15 years old. This is a story that happened to me last weekend. It was a regular weekend night, some friends and I were drinking at my best friend Jared’s house. His parents had taken his little sister to Disney land for the weekend. His 17 years old older sister was still home, and she was a 12 out of ten blonde bombshell. She has perfectly round C cup tits with little pink nipples. She is naturally tanned, and shaves her pussy. I know all of this because a week ago we were swimming in Jared’s pool when Taryn came out for a dip in her tiny red bikini. I could barely hide my hard on the whole time she was around. After about 20 minutes she went inside to dry off. A couple minutes after that I went inside to get a can of pop. I decided to stop and take a piss, and when I opened the bathroom door I saw Taryn completely naked staring at me with her gorgeous green eyes. She didn’t yell or tell me to leave, she just giggled. I freaked out and closed the door. I haven’t been able to stop thinking about how fit and perfect her body was. Taryn is upstairs minding her own business while we are all downstairs drinking. Later in the night everyone starts to head out, and I realize that I am locked out of my house. “Yo Jared, is it cool if I crash here man? I forgot my keys to my house.” “Yea, no problem, you can crash downstairs” he reply's. We stay up to about 2:30 am watching TV and hanging out. Taryn comes downstairs in a pink robe. She was wearing no make up and still looked like a movie star. All I could think about was ripping off her robe to see whats under it. “How was your night, boys?” she asks “It was alright, think I'm gonna go crash though. Alex (me) is gonna sleep in the basement, he is locked out of his place.” Jared tell his older sister Taryn. “Ohh, okkk!” she says, “well, ill see you two in the morning!” Right as she leaves the room, she looks me in the eye and give me a flirty smile. And then she was gone. I head downstairs to pass out but all I can think about is fucking Taryn’s brains out. Its about 3:30 in the morning when I hear someone coming down the stairs. The door opens and someone turns on the lights. I see Taryn standing in the door way wearing the sexiest red bra and thong ive ever seen. I instantly had a boner. “Heyyy, I was wondering if you wanted some company” she says in a raspy sexy voice. “I would love some..” She comes over and sits right beside me sideways on the couch with her legs open. It takes all my power to not look between her legs and at her cleavage. “You know, I've had a crush on you for a long time Alex...” “You're joking. Ive had a crush on you since I was 5 years old. I'm not going to lie, walking in on you the other day was the hottest thing I've ever seen” "So you liked what you saw?” she asks “I mean everyone knows you are gorgeous, I just had no idea how perfect your body is” I say while looking her up and down. “You know, now that you have seen me, I thinks its only fair that I see you,” she says I didn’t know what to do. I was stunned when she said that. “well? What are you waiting for cutie. Strip!” I stood up about a foot in front of her away from the couch, and took off my shirt. Taryn puts her hand on her right tit and starts rubbing it with a naughty looking smile on her face. Then I decide to just rip my pants off as to get it over with as fast as possible When she lays her eyes on my 8 Inch cock for the first time her mouth literally dropped. “Oh, my, god. You have a beautiful cock Alex. Its so big and juicy!” She reaches out and wraps her hand around my rock hard dick. Her and was cold, but it soon warmed up from rubbing my cock. She scooted forward so that she was sitting on the edge of the couch, positioning my cock right in front of her face. I was not ready for what she would do next. Taryn looked up at me with those green eyes as she lifted my cock up against my stomach. She stuck out her tongue and slopped it on my balls. She licked and tickled them before she licked all the way from my balls, up the bottom of my dick, to the head of my cock. Then she twirled her tongue around the tip of my cock while looking up at me, before she engulfed my whole dick deep into her throat. My head instantly jerked back as she bobbed up and down on my dick, slurping and sucking like a professional. She gave the most mind blowing blow job. it was so sloppy and she was playing with my balls the whole time. Within a minute of watching my friends sexy blond sister mouth on my cock I felt the tension building up up inside. I knew I was going to cum and she did too. She took my dick out her mouth for a second while still jerking me off using her saliva as lube and said, “you gonna come for me? I want to taste your hot cum in my mouth. Fuck my mouth, fuck my slutty mouth and fill my stomach with you cum Alex” Taryn then swallowed my cock back into her throat and worked it harder than ever. She was going a mile a minute sucking my dick and playing with my balls. She got down on her knees and was slobbering all over her tits. She looked me in the eyes and I knew I was about to cum. I stood there as an explosion of cum spewed into Taryn's mouth, and she didn’t slow down even a little. It was the most incredible blow job of my life and she didn’t stop when I came. She kept sucking for about 10 seconds and it just extended my orgasm. I've never even seen a better blow job in a porn movie. My knees buckled and I fell onto the couch. I open my eyes to Taryn taking off her bra. As soon a I laid my eyes on her prefect tits my cock started to get hard again. She was still on her knees on the ground and she had moved to be in between my legs. She had a bit of my cum still on her face but that didn’t seem to phase her. She buried her face in my balls and licked my cock all over to get my hard again. “I haven't been fucked in a month, Alex.” She says while giving my still wet dick a tug. “Without saying a word, I stand up and throw Taryn down on the ground. She falls on her hands a knees with her ass up in the air. I tore her pink thong off to reveal a wet pink teen pussy and a perfectly clean asshole. “Oh my god fuckkk meee! I'm already dripping wettt” I walk up behind her and put my dick at the entrance of her pussy. I rub it around on her hot wet pussy for a few seconds before I shove my entire 8 inches into my best friends 17 year old sister wet pussy. ‘OHHH MY FUCKK YESSSS. FUCK ME!!” she screams “shhh Your going to wake up Jared” I say “I don’t give a fuck. I want you to make me cum on your dick. Fuck me like a dirty slut!” That was enough for me, so I pulled my dick out of her. I did this to tease her and it worked as she looked back at me upset. Right as she did I shoved it back in up to my balls and started to fuck her. She was wild. Pulling her hair, panting, moaning, screaming for more. Each time I slammed into her the slap against her ass made her whole ass shake and it was the hottest thing i'd ever seen. I grabbed her hips and fucked her as hard fast and rough as I could. The rougher I was with her, the more she seemed to like it. “FUCK ME FUCK ME FUCK ME FUCK ME” she begged. I could tell she was getting close to an orgasm so I reached down and took a handful of her long blonde hair. I pulled back on it so that her head was only a few inches in front of mine. I leaned back and her back arched. It was like I was riding a horse who went on its hind legs. She was loosing her mind. I fucked her relentlessly until she screamed “ OHH MY GODDDDD DON’T FUCKING STOP IM GUNAA CUMMMMMM” I feel her getting hotter inside as she breaks loose from my hair hold and falls on her face. I didn’t stop fucking her as she had a 50 second long orgasm. Finally she moved away and tried to catch her breath. “that was literally the best orgasm I've ever had in my life” she says in between deep breaths, “but were not done just yet” She stands up and pulls me over to the couch. She lies down on her back and I mount her missionary position. I slam my dick back into her soaking we pussy, and continue to fuck her. From this angle I can watch her tits bounce every time I slam my cock into her. She has her arms above her head and she is looking me up and down in lust. I lean back and rotate her on to her side . From this angle I can fuck her a hard as I want. As I am fucking her my cock falls out of her pussy. As I'm going to put it back in she reaches back, grabs my cock, and positions it to her asshole. “fuck my ass” she says all sweaty and read in the face Without question I push my dick into her tight asshole. Using her pussy juice as lube, I fuck her perfect ass as she lies on her side curled up in a ball with her knees against her chest. This I the hottest thing I've ever seen in my life. I know I cant last much longer inside her ass like this. I continue to fuck Taryn and watch her moan and beg for me to fuck her ass harder. I start to feel it coming, and I decide to just kick it up a notch. I grab her hip with both hands and start fucking her as hard as humanly possible. She is screaming and screeching as I use her ass hole as a sex toy. After about 30 seconds I cant hold it any longer. Her tight wet asshole feel too amazing. I keep slamming her as I pump a massive load of my jizz into her ass. I thought the load I busted down her throat was amazing, but the load I had just put in her asshole felt 10 times as good. After I drained myself inside her asshole I fall back on the couch. She lays there catching her breath, not moving for about 10 seconds. “You are amazing.” She says finally. “I had no idea you were such a wild girl in the sack, Taryn." I say She sits up and looks at me and says, “How about you sleep over next weekend too. There's a lot more you don't know about me...” I didn’t even need to respond, as she stood her up naked and bent down right in front of me to pick up her thong giving me a perfect view of her ass and pussy which was still dripping my cum. I watch her perfect naked tanned ass walk to the door, when she turns back and says, “Night Alex. Don’t worry, this is our little secret. See you in the morning!” She winks at me with her gorgeous green eyes, giggles and gives me a smile as she closes the door and leaves. Holy shit. I just fucked the shit out of my bet friends sexy sister. What will happen next weekend? To be continued....
