I got my botty eather like groceries (M)

So 2003 I'm still living with my parents. I got hurt at work so I'm staying at home. My friend ex is coming to visit me every Friday and also giving me some head. One day I'm in my bed she's doing a great job down there then she tells me to pick my leg up. So I pick them up she is going to town on my balls. She asked me again to pick up my legs so now I'm pretty much in "giving birth position". It was a bit weird but damn she was doing a great job, sucking wile massaging my balls, then will jerk me off wile licking my balls. I was in heaven… then it happened. I felt this sensation it made me jump I hit my head on the wall. She laughed and told me not to move. She told me to keep my legs up she started sucking me again and then again grabbed my dick like if it was going to run away and started licking my ass again. It was intense I never felt anything like it. It felt as if i was having an orgasm but with out cumming. I couldn't talk I was shaking she is jerking me off at the same time. I finally gave out and I started to cum. As she always did she started sucking my dick as if candy was coming out of it. She swallowed it all then she stands up looks at me trying to catch my breath, smiles and say I'll be back let me use the bathroom. I layed in bed wondering what the hell just happened. She came back got in the bed kissed and asked me how I liked it. I just said wow. Never had it done again.
