Exhibitionism with my sister 1

This starts in my adolescence, I already saw porn, I did it when I was alone in my room, as I shared it with my sister Sofia. But always that I had time I used my portable computer and watched. There was a change in my life the time I saw a comic, it was of cousins, I got too excited because I had a cousin who seemed very good to me, with enormous tits, I always fantasized about her. This was the comic.That comic opened me up to the world of incest, I started seeing comics of mom and son, dad and daughter, cousins, and brothers. The last one was what excited me the most, I got really into brother incest. So you know my sister is pretty, we're a year apart in age, being the older one, she doesn't have an exaggerated body, her face could be said to resemble Karely Ruiz, not her body, oh well, but she has normal breasts, they're not big, but she has what it takes to play and a nice ass, worked on because she exercises.
Having a sister like that, sleeping with her in the same room and seeing her sometimes in underwear when she changes, my excitement from watching those incest videos, comics, and stories I started reading made my fantasies about my cousin pass to my sister. Something that was always latent in my life was my exhibitionism, as a kid I always liked being naked, obviously more so as an adult, but I liked it. With the stories and videos I saw, I always liked those where the brother slept with an obvious erection and the sister happened to see him by chance. This made me want to try it, and since we shared a room, it was easy for me to do it, I just had to figure out when. A few days went by and I didn't know how to do it but life decided to make me do it on Saturday. My parents were working in the morning so we were alone. My sister was using her phone next to the TV because she was charging it, wearing a long t-shirt and short, not much of her body was visible. The room was lit by the light coming in through the window since it was open. She was sleeping on her stomach, which made me have a huge erection, I quickly thought about turning over but it would be very obvious if I did. So I waited and just as she went to the bathroom, I took advantage of that moment to turn over, took a look, and my erection was quite noticeable. Here's a picture below of how it looked.I was looking up with my eyes closed, simulating sleep, listening as my sister came out of the bathroom, which is right next to our room. I heard her enter and silence, I was nervous and excited, my cock wasn't giving any more erections. I heard her grab her phone and thought she wouldn't give a damn, but seconds later I heard the sound of photos, I stayed thinking has she taken a photo of my erection? I kept simulating sleep for a while until I got up and settled in, she continued using her cell like nothing had happened. I started talking nonsense to her and that's how the day went on, not much else happened that day. But I had to know if she took a photo of my erect penis while I was sleeping and besides I had left with the urge to see her reaction, so my new plan was to show my erection by accident in these days anew. I'll upload a chapter every weekend, this is just the beginning and a mini presentation of both of us, although if I see that you all ask for it a lot and see a good score, I'll post one mid-week. I hope you enjoyed it, thanks very much for reading.
