My c-boy decides to advertise on the internet that he's selling his virginity to the highest bidder, thinking it's going to be some three-pump chump who will take about fifteen minutes of his time. Little does he know that your guy, the winner who bids $10mill+, has other plans.
My c-boy is at the gym and figures he's alone in the locker room, taking a shower. Your straight guy with a girlfriend sees, unbeknownst to my kid, and becomes curious, maybe even a bit obsessed, and seeks him out.
When they were younger, these kids were best friends, and one day your kid walked in on mine and realized he was a c-boy. He stopped talking to him altogether, and until mine moved away with his parents, he was devastated. Ten years later, mine is on the internet with a cam site, and yours decides to find out what he was missing. He then reaches out.
My c-boy is a porn star and yours is either another porn star, or a fan who runs into him one day at a party, where he takes the chance to introduce himself.
