In high school. In the locker room the difference between my tiny boi dick and the manly (4 times bigger) equipment possessed by the well developed black studs made me feel sexually inferior already as a young man.
When my biggest crush, a really cute next door girl I’ve known for several years but never dared to kiss, started to ask questions about one of the black guys….is he nice, does he have a six pack, does he a steady girlfriend….and of course…you who change in the same locker room and showers at the same time…is he ahem…big..?
I answered all questions, without understanding why, also started to talk about his positive sides and how well built he was. Finally also proposing to introduce her to him at a coming party.
Her happy acceptance gave me what I later understand was my cuckold thrill. Humiliation by introducing my crush (being friend was better than nothing) to a boy way more masculine and with way more sex-appeal than m….and arousement when it took him 10 minutes of flirting before they were making out in front of all people.
I walked her home after the party and she told me all about how sexy and handsome he was and thanking me for being such a good friend.
Needless to say it was the first of many nights I wanked thinking of her riding him and moaning with delight.
I had an almost identical experience with a lovely virgin white girl I had a crush on in middle school when I was 15 and a virgin too.
My rival was an extremely handsome dazzlingly athletic black confident lad of 16 who had gone through an accelerated puberty in the 2 years prior. He was 6'3" in height, weighed 82kgs but already had the body of a sexually desirable young man; very strong, supple, beautifully defined muscle-wise with a well developed high-placed butt which I envied like crazy as I masturbated furiously in my bed as I vividly imagined him vigorously fucking the one-and-only love of my life--in the missionary position of course.
I noticed that my "girlfriend" always lowered her eyes when they met face-to-face and I would often catch her staring at his genital bulge which was big enough when he was wearing jeans, but totally eye-stopping when he was wearing swimming racers for training and competitions at our school baths. It made it worse for me that he was the school champion for not only the 200-meter medley but also anchored the 200 freestyle relay and was a fantastic diver from the 9 meter board.
Long story short, he secretly fell in love with my girlfriend and took her virginity unbeknown to me for fully 6 weeks during which he fucked her in her bedroom whenever her parents were out, including after school.
Throughout the whole 6 weeks my girlfriend remained cosy and affectionate towards me, but I somehow sensed she had been "taken". So during one of our quiet (and sexless) times together, I asked her about my strapping black rival who she increasingly obviously had eyes for.
She broke down in tears and out it all poured---how charming he was and how beautiful he was naked, how sexily he kissed her etc etc.
Strangely I was far from devastated but, to my surprise, as curious as heck about how and how often he fucked her, and of course how well hung he was.
On the latter subject I wasn't disappointed. Using her forearm as a ruler and girthometer she indicated that his erections were between 8 and 9 inches long and super-girthy. To top it off he was enviably uncircumcised (as against my being sadly circumcised) all of which I confirmed in the athletics changing room showers at the earliest opportunity.
Over the next few weeks I easily befriended my rival but never once asked him the details of the sex I told him I knew he was having with my girlfriend, who apart from telling me that she orgasmed easily with him was modestly unforthcoming on the issue except to relate that he "spurted a lot".
My erotic excitement from the experience of being betrayed by my girlfriend with such a spunky young black, who I also came to secretly lust for, quite naturally carried over into my somewhat wild sex-life (which soon included MFM threesomes) with both women and young men which began in my late teens. The story of how I eagerly set myself up to be cucked by my wife and my 19-year-old black lover is related in several posts of mine on this forum.
