I caught my 14 y.o. brother beating his meat one day and threatened to tell mom and dad unless he let me watch him finish off. He agreed and I dont know who liked it best me or him. He used to bring his friends home too and they sat around with skin mags jerking off as I secretly watched them shoot their stuff.
I was 13 when I caught my bro who was a year younger jerking off. I did the same and threatened to tell on him unless he let me watch. He agreed and watching him made me really excited. After he came I went to my room and rubbed myself to climax. After that I made him do it every weekend while our parents were shopping. I don't which one of us found it more exciting....
