This is a true story that I have never told anyone before.
When I was 25 and my little sister was 18, i would jerk off every chance i got (as boys at a certain age do) and there were multiple occasions that my sister would walk in on me doing it. We shared a bedroom with bunkbeds for years which made privacy difficult, for both of us. At first, I thought it was disgusting and I'd get so nervous for getting caught doing it. I'd gotten better about locking the door or waiting until everyone was asleep.
Anyway, some years later our parents went for holidays and we both alone were at home for a week.
And a secret of mine would be i smoke joint sometimes and those days i had the best time and joints of my life and would feel so fucking horny all the time.
So the first night, i came home after smoking alot of joints and my sister was sleeping ( i thought ). the room was full dark with a light of bulb which was dim and after getting on my bed i felt horny and started watching some porns.
Nothing of incest or my sister came on my mind at first. I was enjoying my time of porn on my bed with my boxers on, and it felt hot sometime later so i got nude and started jerking and wanted to finish my self.
So i got out of room to sitting room, all those time i thought my sister was sleeping.
After a while, i was still jerking and the door opened and i suddenly put my hard dick inside and was playing with my phone. my sister got out and she started eating beside me at the sitting room table, but still my dick was hard and it was peeking outside from a side of my boxer. Half of my dick was outside and at first i didnt notice but did notice my sister looking at me sometimes, the sitting was all quite and peaceful. after eating she went inside and i knew she was starring at my hard dick peeking outside of the boxer.
