I was 19 or 20, in college, and passed out drunk. I was molested by a horny classmate after a night of drinking. He sucked me and tried to get me to suck him. But like I said, I was out.
I knew something had happened to me because I was naked in my bed, and I never slept in the nude in those days.
About a week later he confessed what he did, and he said I would probably press charges. Instead I got horny listening to what he was saying. Weird, I know. But what do you do when your friend says he sucked your cock while you were unconscious? Well, I asked him to do it again while I'm awake. And I returned the favor. A few times, in fact.
I realized then that a cum was a cum regardless of how you got it. Could I have a romantic relationship with him? No way. Not into guys like that, but it was fun playing around.
By the way, we're still friends and keep in touch. But what happened in college stayed in college. He's married with a family, and dredging up the past for a thrill just isn't worth it.
It was the first time I ever saw an erect adult circumcised penis, and he had every right to be proud of it.
