My name is Josh and I'm 10 months older than Kara. We have a very playful relationship. We aren't particularly close, but we do mess around with each other a lot and play the occasional prank and so on. It was early December when our relationship became something a little more. We had both just finished high school and were currently on holidays as I was in the process of looking for a job while she was waiting to hear back from colleges. She had always been smarter than me. These holidays I had gotten into the habit of getting up very late and showering around lunchtime.
Kara was up early every day as she is a fitness buff and likes to go on early morning runs. One day in early December I was in the bathroom getting ready to have my shower when Kara burst into the room.
I think it was an honest mistake, the door lock was broken at the time and until the shower started you couldn't tell if anybody was in there. We weren't used to knocking since the lock on the door only broke a few days before. Kara burst in still wearing her jogging outfit. Tight red shorts and a tight red top that showed a surprising amount of her stomach. She is 5"10' tall with a slim athletic figure, shoulder length straight brown hair and green eyes.
I had never really thought about how sexy she was before, but she definitely had that sex factor. Myself on the other hand, wasn't wearing anything. I had just gotten undressed for my shower when Kara came in. We both froze as we realised her mistake. Her eyes darted to my exposed penis and stuck there. I didn't move for what felt like forever.
I could feel her eyes burning a hole into my dick and suddenly it began turning me on. I could feel it getting harder and rising into a full erection right in full view of my sister. It was probably only seconds later, although it felt like 5 minutes, I snapped out of my stupor and covered myself with my hands. Then she left the room and closed the door. She was going to tease me so bad for this, especially for getting an erection in front of her.
When I emerged from my shower Kara never said anything, didn't tease me at all. From then on I found myself thinking about her in ways I never had before. I realised how sexy she was and tried to imagine what her chest would look like topless. It was only fair I should get to see some day, since she had seen me. What a turn on.
The next day I was about to have a shower when for the second time Kara came into the room. I was only topless this time. She said sorry again and quietly left the room, but I noticed her eyes darting across my chest. I wasn't the most built guy, but I had some muscle. Was she trying to walk in on me again deliberately? For the remainder of that day I couldn't stop myself sneaking peeks at my sister whenever I had the chance.
At dinner that night she dropped her fork in the kitchen and barely bent her knees when she bent over to pick it up. This gave me a great view of her tight ass.
My dick immediately grew into a raging hard-on. Luckily I was sitting at the table so nobody could see it, and my parents were facing away from Kara so they couldn't tell I was staring at her ass.
The third day I decided to see if Kara would enter the bathroom again while I was in there. The thought of her seeing me nude again was intoxicating. I almost undressed and waited for her like that, but I chickened out and remained clothed, sitting on the edge of the bath. My dick tented the front of my pyjama pants, already hard from the thought of my sister.
Sure enough Kara entered the room. As soon as she saw me there fully clothed she apologised and went to leave. What would make you think that? I suddenly felt powerful and confidence rose inside me. On pure instinct I found myself pulling my pants down to my knees.
My hard cock popped out into the fresh air and Kara's eyes snapped to it like they were magnetic. We stood there for a while, nobody saying anything. I just thought, maybe I could catch another glimpse.
I didn't think I was so obvious. My sister moved closer to me, today she was wearing jeans and a simple T-shirt.
She slowly reached for my shaft and wrapped her fingers around it. I moaned softly in response. It felt so good. She started pulling on my cock, slowly jerking it as she bit her lower lip and looked straight into my eyes. Then suddenly she stopped. I quickly jerked myself off to ease the tension, then had my shower.
After that incident, Kara started teasing me about my dick. She'd giggle at me all the time, and when nobody was around she'd taunt me with things like "Josh gets a hard on for his sister.
The day after Kara's short lived hand job I decided to get up early. I wasn't sure if she would walk in on me again, so I thought I'd turn the tables on her. I waited for her to get back from her run and go into the bathroom. I waited a few minutes and then entered. My sister was standing by the shower completely nude, her ass in full view. It was wonderfully firm and round. My cock was already partially hard, but as soon as I saw that it almost ripped a hole in my pants.
Kara turned around in shock and covered her crotch with her hands. But there was nothing she could do about her tits. My eyes locked on to her petite pink nipples, they seamed to float in the centre of her perfect mounds.
Her breasts were probably a B cup and looked like a nice generous handful. I think my mouth dropped open slightly as I stared at my sisters tits. I replied, "I thought it'd only be fair if I got to see you. My eyes moved down from her perfect tits, across her perfect flat stomach and landed on her pubic mound. She was quite hairy down there, but I could see that it was neatly trimmed and wasn't growing wildly.
Kara then pointed at my crotch and said "Your turn. While Kara stared at my cock, I slowly moved towards her and reached for her jugs. I grabbed a handful in each hand and slowly massaged them. My cock jerked from the mental stimulation. Then Kara surprised me. My sexy sister reached down for my ass. She grabbed a cheek in each hand and pulled my pelvis towards her.
My dick hit her stomach and slid up past her belly button as my body pulled towards hers. I released her tits and grabbed her ass as well. Her breasts squashed against me and my cock was now mashed between our bodies and I couldn't help myself. I thrust forward and slowly pumped my cock against my sisters navel. I began to pump against her stomach a little faster, but soon she pulled away.
Then she slowly lowered herself onto her knees leaving my cock only centimetres away from my sisters face. She then grabbed my shaft at the base, angled it up again and slowly licked my cock all the way from the base to the tip. Then she looked into my eyes and smiled. You see, Kara has perfect massive sensual lips. All through high school she was teased for having blow job lips, and now I was actually experiencing them being used for that purpose.
My sister started to bob her head on my cock, stroking the underside of my shaft with her tongue. My hands moved to her head and lightly held onto some of her hair, then pulled on it slightly as she moved back and forth over my rock hard cock. I could tell she had done this before, she worked her tongue in a way that almost made me explode with each stroke. I shot blast after blast of hot cum into my younger sisters mouth.
She pulled herself off my dick slightly at the same time to try and get some air.
