Your story wasn't boring. A similar thing happened to me when I was in high school. One time this guy I knew named "Jake" asked me if I wanted to get together at his house and smoke some excellent dope he had, since his parents were away and he had the house to himself. I was very surprised at the invitation because he always came off as being a very macho kind of guy, very different than me who was quite effeminate and was generally shunned by the other boys who were constantly calling me "fag" and "queer" all the time. So, I went to his house, we smoked several joints, and got fucked up. It was a really hot day so Jake suggested we take off all our clothes, which we did. It was then I noticed that Jake had this really big dick which I couldn't help looking at. Jake said something like "You like what you see? Then go for it!" To make a long story short, we both ended up sucking each other off and we came in each others mouth. Jake turned out to be quite an experienced cocksucker. Like your friend, Jake also threaten me if I told anyone in school about our encounter. He said he'd really beat the shit out of me if I said anything so I never did.
You should be nicer to him. You ought to offer to suck his dick and let him come in your mouth and swallow it and let him see it. Then tell him you will be at his beck and call anytime he wants his dick sucked to orgasm.
