“My little brother has a big dick” part 3

For those just reading, my sister and I had a long term incest relationship that started off with a blowjob ons. Family camping trip. After an awkward week, we re-ignited the sexual relationship when she gave me a blowjob in a changing room.

I should mention that all this was years ago (I’m much older now), so I’m writing this based on memories. As a sort of “memoirs” of our old relationship (basically, none of this is recent).

This is the story about the first time we had sex. she was fighting with an ex over the phone. They had dated a while, but he really started to talk down to her and do shitty things (ie: he wrecked her car, and never bothered to help pay). She broke up with him after finding out he was fucking one of her friends. He kept trying to get back with her, she’d listen a bit, then a fight would break out. It was a vicious cycle. All the while, I was in the background of all this just wanting another one of my sister’s magical blowjobs. The sex didn’t come right away, things built up to it.

So, one day, my sister was having a bad fight, over the phone, with the guy. There was name calling, shaming, yelling and cursing. I was in my room playing video games, hanging out in my underwear (had no plans to go anywhere). Every so often, I sister would walk by. She was wearing these hot booty shorts style underwear, which rose up her ass, and an oversized sweater. She got so mad, that she hung up on him. She turned and looked at me, while I was sitting on the bed wearing my underwear. She looked right at the bulge of my penis, easily visible from my tight underwear. Without saying anything, she rushed to me, climbed on top of me, and started grinding on my fat bulge. She took off her sweater, revealing her tank top and braless tits, which flopped everywhere as she bounced on me.

“Fuck it! I don’t care!” She said, as she kept grinding on my dick, which was now fully erected. I could feel her labia, massaging my dick with every thrust. It felt so warm and, within seconds, I felt her getting wet. I was speechless from the pleasure, but managed to ask “what’s gotten into you?”
“He fucked TWO of my friends, with his little dick, wrecked my car, treats me like shit! Let’s see how he likes it!”

My sister rode me harder. Her big tits slapping my face, from time to time, making a smacking sound. On occasion, I heard her having sex with her boyfriends from my room, but I was witnessing her in action. Although not full penetration, my bulge would stab her pussy and rub against her clit enough to stimulate her. She was loud, letting out sexy high pitched slutty yelps, like a playful dog. She kept aggressively grinding and riding me like she was a prized bull rider. What turned me on most was that my sister was a “talker”. She’d say the sluttiest things that would just come out. At one point, between her slutty yelps, she’d say repeatedly “big cock…biii…ca…big cock!” She struggled to say the words between trying to catch her breath, from the exhaustion of ridding the shit out of me, and her slutty orgasmic yelps.
“I can’t take it! I want your cock! Your big, BIG cock!”

I wasted no time. I pushed her down on the bed, took my underwear off (practically ripping it off), pulled her underwear aside, and began trying to fit my dick in. For a split second, I paused, thinking “oh shit, this is it. I’m going to lose my virginity to my big sis. I’ve fantasized about fucking her for so long!”. I peeled my long foreskin back, revealing the fat head of my dick, and started slowly pushing it in. I couldn’t quite tell how to put it in.

My sister put her hand on my cheek. It was a moment that took me out of the lust. She said “it’s ok. I’ll help you”. She grabbed my penis, lined it up where it should be, then said “Go slow, little bro…You’re bigger than I’m used to”. I began pushing it in, feeling her pussy gripping my dick in an amazing way. She threw her head back immediately. Barely getting her words out, she said “Shiiiiiit, oof! That’s big! Big cock!” I asked out of concern “are you ok?” She looked at me and said: “I’m fine! You’re just the biggest cock I’ve ever had, by far!”

I didn’t really know how to move my hips. My sister, past a certain point, said “here, I’ll drive!” She had me sit on the bed, leaning against the headboard, and climbed on top of me cowgirl style. She lined my dick up, and shoved it in. It felt as tight as before. She let a yelp and a “FUCK!” as she sat on my dick, taking it all in. She began fucking me like a robot. I just laid there, incapable of intelligent thought. The only thing I thought about was resisting the urge to cum too early. But her pussy was gripping me too tight, and the slutty things she told were like music to my ears!
“Fuck fuck Faaaaaaaack!” She said, as she continued using my big dick like a tool to punish her pussy. She rode me to the point of exhaustion, stopping to take a break. She leaned on me, gasping for air. While she played with my hair, she said “Fuck…You’re just so fucking big, little bro! Fuck. I’ve never had dick this big! I love it! I fucking love it!” As she continued to talk dirty, her hips started thrusting like they were moving on their own. She went into full throttle again, using my dick for her own pleasure. I could take it anymore. Between her hard thrusts, her tight pussy, and the slutty things she kept saying, I couldn’t resist. What did me in was when she shifted her voice, and started talking in a slutty sweet way (I heard her once or twice do this with her Bfs).
“Awww! Look who’s giving their big sis all their big cock! YOU! Yeah! That’s right! My big cock little brother! Yeah you are! Yeah!” She was talking like a high pitched cheerleader! Where the hell did she get this stuff from
“You can fuck big sis’ tight pussy anytime you want! That’s right! Bc you’re my big cock little bro! You’ll always have tight big sis pussy!”

It finally happened. I came so hard I yelled as my legs shook uncontrollably. As I shook like I was having convulsions, my sister continued her slutty high pitched cheerleading: “Oh my goodness! Your big cock is coming! Oh I feel it pumping inside me!” She hugged me, as I laid there in a trance like state. I had my first time, finally. She got off me and began queefing out my cum. “Wow, you did a huge load in me! Good thing I’m on the pill!”

She laid near me, caressing my chest the way you’d do to a lover. She told me “Even me doing most of the work, that was better sex than I ever had with Dan!” (Her ex). She gently stroked my spent, flaccid penis saying “Fuck, little bro! That dick made me sore! I’m gonna have to ice my pussy!” She said, going back into the role of bratty jogging big sis.

Despite not doing much of the action, my first time was amazing. Eventually, I learned how to screw better and, once that happened, I started being able to fuck my sister senselessly.
