Not many people responded, but thanks to those who have indicated you want to hear all about me from the start. It all started for me rather close to home.
I have 2 older brothers and as children we would often play games like "Cowboys and Indians" or "escaped prisoner" where I was always the fugitive who would soon be caught tied to a makeshift tree or post and then stripped naked by my brothers. Or else we would play Hospitals when again I would be the patient and I had to be naked while my 2 doctors had to examine me. These games must have planted the seeds of my exhibitionist behaviour since I was never shy about being seen in the nude. I don't remember what age I was when these games first began, but I do know that I was 10 when I had my first taste of cum.
My brothers were 15 and 12 at the time and we were playing one of our Hospital games as we often did when we were alone at home. I was laying on my bed, already naked and I had been thoroughly examined by both "doctors". Whenever we played this game they would always take my temperature by inserting the thermometer into my pussy and then they would have to examine me down there with their fingers and a torch (so thay could get a good close look, not to insert it in me!).
This particular day my oldest brother diagnosed me with some illness or other which he said required a special medicine and before my younger brother could hand me the usual imaginary pills, he told me to wait while they went off to prepare it. He inserted the thermometer back into my pussy and they left me laying there, telling me not to move.
It seemed like I had to lay there for ages and eventually they both returned and they had a tea cup with them. They showed me the special "medicine" in the tea cup that they had prepared for me. As I looked at the contents of the teacup I had no idea that the thick white liquid I was seeing for the first time was their cum.
My brothers took turns in feeding me their combined sperm with a real plastic medicine spoon and I remember thinking that it did not taste very nice, but that medicine was not supposed to taste nice, so that was OK. They fed it all to me and I could tell they were really pleased about this but at the time I didn't know why.
We played this game loads of times over the next couple of months and I would always be treated with what they called my "special medicine". Even though I would sometimes ask what it was or how they made it, they wouldn't tell me.
This game had been going on for about 4 or 5 months when one day it was just me and my younger brother playing. He decided that it as it was just the 2 of us he would be the patient this time and I was a nurse. I had seen both my brothers naked plenty of times before and I had seen them both with hard-ons too, but this time he told me to stroke his prick and he showed me how. After a few minutes he said that he was ready to give me my medicine and that I should go fetch a teacup. I was not sure what he was going to do but I do remember being fascinated and totally amazed when I finally saw my medicine coming out of his little cock!!!!
He fed it to me as always with the spoon and I took it. I was really intrigued about how this stuff could come out of his willie and so he explained to me what it was and how it worked. My first sex education lesson from my 12 year old brother! We never let on to my older brother that I knew it was their sperm I was being given to swallow, and we kept on playing our Hospital game and I kept on eating my brothers cum for many more months.
It was not too long after I learned where the white stuff came from that my younger brother persuaded me to give him a blow job, telling me that we didn't need the teacup but that I could take my medicine direct from his cock. I simply adored having his little prick in my mouth, rolling my tongue around his shaft and over his knob; and that first time when he shot his warm salty, sticky load directly in to my mouth I was hooked forever

My older brother only really played the game with us that one year (although he did in fact get a blow job from me when we were on holiday a few years later, along with a few of his friends - but that's another story altogether!). He had got himself a girlfriend and spent less and less time playing with his younger brother and sister.
My younger brother and I were much closer and he kept feeding me his cum for many more years

You will understand now why I was not phased by having my son feed his cum to me and his sister recently in the pancakes.
I can't remember when I started to like the taste of my special medicine, or if I just became accustomed to it, but I have always been eager to swallow it ever since those early days.
