Making of a slut

It all started the summer after my 7th birthday! My father was in the military and was deployed and mom was a nurse and worked lots of hours. I did have 2 sisters that were 9 and 10 yrs older than me and were never around so I was watched by my 16 yr old Cousin John. I would be dropped off at his house at 7 am every morning and was picked up by 8 pm every night. The first few weeks were just average nothing happend would get there do the normal thing then get a bath and be ready for bed when my mom picked me up.
He had been watching me for about a month when he asked me if I wanted to play a game with him it would be our secret and I loved to play games so I was all for it. So the first day he took out his cock and told me that rub it up and down and it would get hard and if I did a good job it would have white stuff come out and if that happened I won. So I went to stroking for all I was worth and thought it was neat that it got real hard and after a bit he shot white stuff all over my hand and I was so excited I won. We played this game every day for a few months and I always won I was very excited that I was so good at this game.
We then progressed the game he said that he wanted me to put his cock in my mouth and see if I could get him to shoot the white stuff without using my hands.
