This was a long time back, probably 3-4 years ago. I was probably 19-20 (M) and she was the same age as me. I have been someone who had to supress his sexual urges for a long time. I was struggling with my personal life at the time.

Her & I, We've been good friends since childhood and we've always had that spark. We've also made out a few times before this but it was just first base. As I was hurt, upset and angry during this phase of my life, my sexual urges intensified and whenever she was around. This time around we started going second base. She knew my libido is higher these days.

We had a family gathering a day prior and everyone was leaving in the morning. Coincidentally it was just me and her upstairs and everyone downstairs were doing their chores. I went and took out my dick infront of her, this spontaneity turned me on and she noticed me going hard. Reluctantly so but she grabbed it and started blowing me. A few minutes in and we heard somebody coming upstairs and we stopped.

A week later I got to know that her parents are leaving someplace in the morning. I texted her prior night that I'll come over once they leave. I went to her place and I got a nice head. I was on the edge of bed and she was on her knees. She made me cum in her mouth and she went in washroom to spit it out.

The taboo feel of this orgasm turns me on everytime I think about it. Incest is pretty common where we come from. After that she tried proceeding things later on but I'm in a relationship now but I do think about it sometimes like this.
