A few months ago I used to be a crazy porn addict and an incest fan, so one day I started watching porn as usual while my sister decided to go take a shower. I kept hiding my porn tab but once she went in and got all undressed, a fire in me lit up, and I said fuck it. I went over to the bathroom quietly, and we used to have this little keyhole where you could see almost 90% of the bathroom, so I looked at the shower first but I didnt seem to find her, next thing you know BOOM there she is, in all her gorgeousness, my naked sister, she was flaunting her boobs, and her beautiful but slightly hairy vagina. I couldn't help myself at all and my jaw was dropped, drool literally fell to the ground. I kept staring at her for 5 minutes before she turned around and I saw her ass, her pussy slightly being shown from the gap of her thighs. I couldn't believe it, the next thing you know, I started to take out my dick and start stroking it, I kept thinking "imagine how good her pussy would feel" and thats what kept me going. She finally finished showering after about an hour, which I was staring at her the entire time, and I rushed back to the bed and acted like nothing ever happened.

I actually did this a good few days before we had to shift homes, but god did I have fun doing so, the feeling of taking risk and being in that spot was absolutely terrifying but good.

I just pray every day that we get another bathroom with a wide open keyhole.

(this was all when I turned 18 and she was 21)
