We were both 15-16 and I had a terrible crush on him, my best friend. I just knew that I wanted to touch him, to kiss him, to make out with him and, why not, hopefully to do something more adventurous, things I had only read about in naughty magazines. One day, I finally took the plunge when we showered together after a swim. Seeing him naked gave me an instant hard on —oh, to be 16 again!—, which of course he didn’t fail to notice. I dared touch him and, since he didn’t resist much, I fondled his body, worked my way towards his uncut dick and stroked it to make him hard. I don’t know where I got the courage to kneel in front if him and take his cock in my mouth. It was pure instinct, guided by sheer lust, and it just felt wonderful in my mouth, like it belonged there. I played with it, sucked it, licked it up and down and, naturally, he shot a huge load in my mouth, which I greedily swallowed. Beautiful. That was my very first blowjob, not reciprocated, and the rest is history.
Unfortunately, he did not share my feelings and he was actually quite embarrassed at what had happened. We never did it again and our friendship suffered. A few years later, we parted ways and we have not been in touch again. One-way puppy love, and fantastic memories.
