This story is true and began some years ago. It seems time now to tell it here on Solo Touch.
Uncle George is my mother's kid brother who stayed with us one summer while he hunted for a place of his own. He has never married although he has always had a bunch of girl friends. Unlike many of my schoolmates I never fooled around with other kids but early on discovered the blessings of being uncut and began masturbating quite young.
My mother was a single parent and now I realize how tolerant she was when that habit began to reveal itself on my bed sheets and semen stained jockey briefs. She honored my right to privacy as I entered puberty and became a typically horny adolescent. My room was my domain at least until many years later Uncle George moved in for six weeks or so. The only available room for him was mine with an extra bed in it. So began a new chapter in my masturbation.
Uncle George fascinated me. He was lean and fit and very masculine and not at all shy about exposing all that to his curious younger nephew. It wasn't long before he caught me with a spontaneous hardon which I failed to conceal and he laughed and lying in just boxers on his bed began to tent them enormously with his own. I'd seen him naked often by then but never he or any male before with an erection.
He let it out of his shorts, in fact pulled them off, and and wide-eyed I compulsively began rubbing my jockey bound bulge. He laughed again and swung around sitting on the side of his bed facing me sitting opposite on the side of my bed and he openly began to casually masturbate. Men will be men he said and suggested I free myself up and join in.
Lust overcame my shyness but it all was more than I could handle and my load shot off almost instantly. I stayed hard watching Uncle George masturbate his beautiful uncut cock and balls and mightily ejaculate on his chest and belly. Uncle George became my masturbation mentor. I welcome comments on what seems to me a natural MM situation even though it's an uncle/nephew one.
