It was a Saturday morning. My parents had traveled to a wedding. At home were my little sister (16) and I (19). I was getting ready to go to the gym. My sister was in her room listening to music. My mother called to see that we were OK before we left for the wedding and free live sexe asked me to look after my sister.
I was almost ready to leave for the gym. All I had to do was put on my shorts and T-shirt and put on my shoes. So from the one who was going to my room to get the clothes, and wearing only a pair of sport (tight) pants, I pushed the door to my sister's room, which was ajar. My sister's back was to the door. Standing up. Hair caught in a high ponytail. Dancing. And wearing only a bra, a thong and some short socks.
My sister is hot. Very hot. The kind that's always surrounded by friends. She's 172cm tall and weighs 52kg. Her hair is brown. She has super long legs and a big ass (for how skinny she is) and she is upturned. She also has a pair of piercings: tongue and navel. So yes, she is very hot. But I've never stopped to think of her as just another girl... But there I was. I couldn't stop watching her ass move from side to side and up and down. Without noticing it, and I was only there for a couple of seconds, my dick started to get hard.
Suddenly, my sister turns around and catches me there looking at her like a freak. Her scared face turned to surprise when I noticed that under my tight pants my hard dick was showing. Then I realized I had a hard-on, but it was too late to pretend. The expression on my sister's face became dirty. She was smiling as she bit her lower lip. I didn't know where to look. I knew I shouldn't keep looking at her, but I couldn't stop. I liked what I saw. I looked at her face, but she had her eyes pinned to mine (and my underwear), I looked down and noticed her small but firm breasts under my bra... but this isn't helping, I thought to myself. I kept looking down at her thong and legs when I heard her say, "even my brother can't resist my ass. I was super embarrassed. I turned around and started walking towards my room which is in front of hers. She said, "What are you gonna do, jerk off to my ass now?" Not what she said, but how she said it. I didn't see her face, but the tone was like she wanted to see me. I stood up. My heart started beating super fast. I turned around and started walking towards her. She smiled again. She turned and leaned forward, put free live sexy web cam her hands on the desk and started moving... very sexy. Then she said "What do you need to see him again?" I said yes as I got very close to her. 1cm or 2 at the most. She kept dancing to the song that was playing on her playlist. I started thinking that if my sister already knew that I was horny and that I was going to jerk off thinking about her, why not do it in front of her. I had conflicting thoughts, but in the end I put my hands on her waist while she was dancing. My heart was going to come out of my mouth as fast as it was beating. I got closer and started rubbing my dick (inside my underwear) with her ass. She didn't try to escape. On the contrary, she was laughing as she said I wasn't the first guy to rub up against her. I was super excited. I could feel my dick wet inside my underwear. I stuck my right hand in my underwear, pulled out my dick and pulled my underwear down to halfway down my thighs. My sister's face was a surprise and for the first time I felt her get excited. "Wow" she said when she saw my dick. I have a pretty big one and she didn't expect it at all. I started rubbing my hard, naked dick with her ass and her thong.
She asked me if I was going to jerk off in front of her, but I didn't answer. I subconsciously thought that, if it had come to this, something else might happen. I wasn't sure what I wanted to happen, but I had gotten super horny and wanted to come with that little doll body.
After rubbing her ass, legs and back I went for her tits, always from behind with her bent over in front. Her breathing accelerated. Her nipples got hard. Her right hand touched my thigh looking for my cock. Between sighs she told me that she had never seen such a big dick. I unbuttoned her bra. She fell over the desk and from behind I could see those tits the perfect size to squeeze with my hand. Her hand found my dick, I jerked it off for a minute or so and suddenly, free live sexy webcam she turned around and pushed me onto her bed. I fell backwards.
She lay down next to me and started jerking me off. Looking at my cock like it was a giant three-color ice cream. Her hands aren't big so my dick looked even bigger. I bring her face closer to my dick. I thought he was going to start sucking my dick, but no. He spat on it and started jerking off. Slowly. Up and down. Staying a little longer in the head, which was glowing from his saliva and my pre-run. He was looking into my eyes with a face that was a mixture of a mischievous smile and excitement. For twice I thought I was going to run. I made a comment about his legs and his ass. She laughed. She asked me to sit on the edge of the bed. As I did so she told me that her ass was the part of her body that she liked the most and the one that drove everyone crazy. She stood up, her back to me. I put his hands on the floor, folding in half like a book. And he started moving his sexy ass.
I couldn't believe that until that moment I had never thought about how hot my sister was. I wasn't sure we wanted either one of them so I started jerking off with the intention of coming over and watching her ass wiggle. Then she sat on me with her back to me and kept dancing on my dick. I wonder if he was enjoying the view... His pussy was rubbing against my cock, I could feel his thong soaking wet. I grabbed her by the waist and pressed her against me. I stroked her ass and legs all the way down to her feet. I squeezed her feet (in short white socks) while she rubbed like crazy with my dick. With so much dancing my dick ended up between her thong and her pussy. There I was about to come again. She grabbed my dick, softly but firmly, as if she was a porn actress and had been doing this for 10 years, and made it completely vertical. I thought he was going to stick it in but he didn't.
He put it between his thong and his belly, as if he was riding me, but with his dick out. And he danced. I looked back every few minutes to make sure I was enjoying myself. And he did. Probably too much.
After a while of riding me, he did a pirouette and jumped on top of me. The stance was such that upside down, she's lying on top of me at the height of my dick. Her legs to my right, bent at the knee, and her socks pointed at the ceiling. To my left her tits hung down while her trunk was slightly tilted towards me, leaning on the bed with her right elbow. My cock between her thighs, her pussy and her thong and her left hand caressing the head of my cock, which is getting wetter and wetter. I was able to grab a couple of cushions and pillows from the top of the bed and put them behind my back so I could sit a bit and see everything from above. It's like my sister is inside my head and I can see what she wants me to do. I never thought about that position, but it was just perfect. I could see her excited face, her tits, her ass, her legs, her socks and she was stroking my dick... but I didn't know that this wasn't a static position.
I would look into her eyes and wonder if she was enjoying it and tell me that she was very proud of her ass and happy because even I couldn't resist her body. While she was talking to me she started to contract her abdomen, moving her ass up and down. I could almost make my dick disappear completely between her thighs and her thong and when she lowered her ass against my thighs and my dick reappeared, her left hand was waiting and her fingers free live sexy webcams caressed the head of my dick in circles. I had to grab her ankle with my right hand while with my left hand I squeezed her left buttock so as not to interfere with what she was doing. I didn't know where to look. Far from being embarrassed that my sister was jerking me off, I was getting more excited than ever before. I was looking at her face with a half-sided smile in between sentences. I'd look at my dick and see her ass and her mules coming up and down and gently caressing her.
Not even a minute had passed when I started moving and moaning, but before I could ask her to stop, she made me explode, so that my run passed between her fingers and reached my face and in her fall covered part of her ass and her ... thighs. She was surprised by the cumshot and started laughing at the same time telling me that I wasn't the first one to cum before I started fucking. I stopped moaning to scream as I kept stroking my glans. I grabbed his hand tightly to make him stop and when I looked at his face I could see a proud smile. She was proud to make her muscular older brother, with the biggest dick she had ever seen and the most experience, come in a couple of minutes. Despite her youth, she had the body, the look, the attitude, and the words to get any guy to do what she wanted. Or so she thought.
