yeah im bigger than all three of my brothers and youngest of all (different dads) once when i was 13 they carried me outside and out behind the shed and stripped me down to nothing. then they held me down and one of them grabbed my cock and started jacking me off while they got naked. they said they were going to prove a point once and for all. "they were bigger because they were older." while one jacked my cock the others would beat off to get hard. at the same time i am getting hard too. after several minutes all of us are fully hard. then one at a time they put their dicks next to mine for comparison. mine was longer by several inches. and much thicker than theirs too. i was so embarassed i didnt know what to do. then they started beating mine off again so hard trying to make me cum. after several minutes i did and they all took turns "squeezin out the juice" as they called it. sometimes two at once. then when i was all out they made theirs do and shot it all over mine. then they just got dressed and went inside and left me outside whith no clothes. later they let me in just before my dad got home and made me swear not to say anything. for years after that i couldnt even take a shower without one of them coming in there to see it. sometime i would wake up to two of them holding me down while one of them jacked me off until i came.
