This happened when I was 13, and had been masturbating for 8 years although I had ben ejaculating for only 6 months or so.
My friend Alan and I had been jerking off together after school at his house every day because he did not have brothers and sisters as I did, and his mother did not get home until after 6 o'clock. One day when we were in the middle of our first session, the bell rang. Alan put his pants and shirt on, went to answer the door, and I went to the bathroom with my clothes in my arms. It was our friend Brad who came over to hang out with his friend. He looked a little quizzical when he saw Alan barefooted. He got very curious when he saw me come out of the bathroom. His curiosity went into orbit when he saw Alan's briefs on the floor. He asked if he should leave and come back another day. Both Alan and I wishing to hide what we were doing said no, and Alan asked if he wanted a coke. He accepted. Alan asked if he wanted to play cards with us. He proposed that we play truth or dare. We agreed and he bean by asking the usual silly questions such as, do you skinny dip?
Both of us answered that we have. His next question was to Alan, and it was:
Do you jerk off?
Alan admitted he did. Next he asked me tha same question, but before I answered, I said to him that he should tell us if he jerked off. He admitted that he did, and I answered yes to his question.
That was sort of the end to the game, although he asked if we jerked off together. After hesitating we admitted we did. His next proposal was that the three of us should jerk off in a group. Alan and I agreed, we all stripped, lubed up, and did our things.
After we cleaned up, Brad suggested we get together at his house on Saturday and have a contest to see who could jerk off the most. We could have all day to ourselves because his parents and sister would be gone all day nd we would have his house to ourselves. We agreed, and that saturday Alan and I arrived about 9 o'clock. The three of us had an exhausting day.
