i had this sixteen year old cousin and she was pretty shrewd for her age and pretty naughty too. when i was 13 i told her about this funny tickling feeling i got when i shinnied up trees. for the next few days she would try to get me to shinny up trees and light posts "to see how far up i could get". i couldn't get far because the tickling feeling was too much. one day we went to her house and down to the rec room. she told me to pretend i was shinnying but to do it on the arm of their couch. doing that i got the same wonderful almost too much for me feeling. she somehow knew i was ready and she told me to stand up and take my pants down, which i never would have done normally. i did it even though i felt embarrassed and i kept them down even when her 12 year old sister came downstairs and saw us. my cousin put my hand on my penis and told me what to do with it. i could hardly stand the feeling and would have to stop but she kept urging me to keep doing it. it happened in front of them, my legs got wobbly, my butt muscles tightened and i started gasping from the intense tickling in my penis, then a few pearly whitish drops burst out and landed on their carpet. When it was over a wave of shame came over me. i pulled up my pants and got away from there as fast as i could. it seems innocent now and it remains a family joke but i'm still amazed that julie knew enough about the power of male hormons that she could manipulate me into letting her and her sister watch my first ever ejaculation, which to me should have been a personal thing.
