She gave her Brother a blow job

Sophie sat on your knee and said "Bless me father for I have sinned. When I was 14 I gave my 16 year old brother a blow job."
You knew what she was talking about. But you just had to play along "You gave your brother a blow job. What is a blow job?"
With out any more prompting she was on her knees in front of you. Sophie then undone your fly and pulled your cock out. "A blow job is when a person sucks a man's cock untill it blows cum. This is how it is done."
After saying that she started licking the head of your cock before deep throating the shaft. You just sat there with out saying a word as she sucked and licked your cock.
When you blew your load she caught most of it. But a few stray drops escaped and landed on the hand she was using to hold your shaft.
After you finish cumming. You watch her release your cock and lick the last few drops of cum off of her hand.
Then she sat back on your lap as though nothing had just happened and started talking from where she had left off. I gave him a blow job once a week until our 18 year old brother caught us and then I had to suck both of them off once a week.
My older brother had a bigger cock and his cum tasted better.
