My cousin and I
When I was younger, I spent my summer vacations at my grandma's farm, where there were two houses, my grandma's, and my uncle's.
Me and my cousin Brad would spend the whole summer riding bikes, playing among the animals (cows, dogs, etc.), playing fight, burning stuff, and doing any other mischief boys would do. Brad is a year Younger than me.
At night, Id sleep at my grandma's and he on his own house. I can't remember when It started, but probably with a talk about dick size. He asked to see my dick, and I showed him. Not sexual intentions by that time, just curiosity. He didnt show his own, because he was shy, probably about his size.
Later in that summer, we would find any excuses to be alone and play showing dick. We started taking showers together, and play nude. His parents were fine because of the water saving.
I remember we found a magazine collection on our uncle's truck garage, not playboy, real porn, and spent times wondering If our cocks would get big as the guys in there.
Finaly, later in that summer, we started the movie watching phase. Nighttime, we sit in his couch, under a blanket, and he'd handle my dick. It wasnt realy jerkoff, just play with my foreskin, balls, etc. (Were both uncut)
Later, he also let me do the same to him, and slowly lost his shame.
At the end of this summer, we started betting blowjobs on our games. "If i Win this running you own me 5 blows". That meant that the loser has to put Winners dick in mouth and go up and down 5 times. It was more about humiliation for the loser than for realy please the Winner.
And as sudden as It stated, finished when we went back to routine. Ive started seeing girls, and had no more interest on guys, until I found that sub and all those Memories came back.
Hope you enjoy, and forgive my grammar, since english is my Second language. Feel free to ask any details in the comments, and please be kind.
