Family Flirt
Some years ago, both myself and my sister had partners. Her BF and my GF got along quite well. The four of us hung out frequently. Drinking and smoking, we we all young and highly sexual. Often, our partners would comments about my family being sex addicted.
One day while alone with my sister, I mentioned how our partners couldn't keep up with us in bed. We laughed about them wanting to stop after a short time but we always wanted more.
She jokingly said that they better suited for each other sexually. I said yeah, just like we would be better suited sexually. She said, imagine us doing it? I said, we would probably stop from being exhausted, not because we've cum. She said she has seen my cock hard and knows it would make her cum heaps. I said, Imagine if our partners could hear us right now? She said that she would die if they could hear us. They'd probably think we do it all the time. I said, If I can be honest, I have looked at you at times, and been turned on. She laughed and asked or stated, Haha, you'd smash? I smiled and said, I am a horny young man, of course! She laughed and said, You've probably got a boner right now. I said, we're talking about having sex. That always gets me hard. She said, yeah, but I'm your sister. You don't have a boner for me? I said you're hot, and talking to me about sex. I definitely have a boner. She said prove it! I said, well don't you get horny talking about sex? She said, I am soaking wet right now, my pussy is throbbing. See? With that she opened her legs so I could see up her skirt at her wet panties. I said, are you wet from taking about sex? Smiling, she nodded. I showed you mine, she said. So I said No, that was just underwear. Immediately she pulled them to the side and I was both in shock and super turned on, staring at my sisters super wet smooth pussy. She was masturbating while showing me. I didn't talk, I just took out my throbbing cock, as I moved closer kneeling between her legs. Having our swimming gear on made this so much easier, we were naked and before I knew what I was doing I was rubbing the head of my cock up an down on her pussy lips. This is so wrong she said, as I began sliding it inside her. But it's exciting, I said. I have half my cock inside my sisters pussy, and it feels amazing! She arched her hips towards me and said, put it all the way in. Although she was tight, there was no resistance, so I kept exploring my sisters vaginal canal. When our pelvic areas began to mash together, I knew I was ball's deep inside the one place a blood sibling should never be. She let out a little whimper, and I as if she was okay? She began twitching, saying, Yes, I'm cumming! I hadn't even started pumping and she was actually cumming. Her tight pussy was contracting around my shaft. My ball seemed to love this action and began firing off my highly taboo jazz deeply inside my sisters orgasming can't. I am too! I blurted out, while I came harder than I have ever cum before.
We managed to grind against each other while cumming, but we didn't have the full thrusting we had both imagined. I had my dick in my sister for two minutes and half of that was spent orgasming! After the orgasms eased, I collapsed on top of her. We both caught our breath, and her face close to mine, she looked me in the eyes saying, you still feel hard. Well maybe now we can go longer, I said. We then began to really go for it. Hard, deep, and fast. For some reason we stayed in missionary position the whole time. After about maybe 15 or 20 minutes, pounding in and out of her, she had achieved a second, then third orgasm. On the third one I couldn't hold back and said, I'm going to cum. She gripped me tightly with her arms and legs, so I knew she wanted it in her pussy. This time, I made it better by pumping the whole time. Now we were both panting in each other's arms while the orgasms finally settled down. This time, I immediately began to go soft inside her.
We cheated a few dozen more times before guilt put a stop to it. Nobody ever found out, and we rarely talked about it, because talking leads to doing. We never used protection because she was on the pill, and I always nutted inside her.
I've never told anyone about this, apart from right here, now.
