I was 17 and riding the bus to my girlfriend's as I did every weekend, she lived about 2 hrs away from me. A dark-skinned guy in his 40s got on the bus, looked around and sat next to me. He chatted me up about where I was going and after I told him a little about my girlfriend, he lowered his voice and said "but you really want to suck a dick."
I'd gotten aroused by seeing cocks in porn before but I never had really thought concretely about having gay sex myself. Now this guy was in my personal space and then the moment passed when I could have said "I'm not interested". I swallowed awkwardly and he said "yeah, look down here." I looked and saw his cock stiffening in his pants... and the sudden possibility of being really able to do it made me really want to do it.
"We're at my stop now. You can come with me or stay on the bus, up to you." He stood up and started walking to the door. It was probably only just a minute to the bus stop, but it felt a lot longer... I felt almost sick with this weird pressure. I looked behind me and he was at the door looking at me. The bus slowed down, stopped and the door opened, he stepped out. After an endless second, I jerked myself up, ran for the door and caught up with him. We got to his apartment, he had me strip naked and then finally took the lead fully as he put his cock in my mouth. When he came, he held my head and shot it into my throat without ramming his dick in, I learned later to appreciate that 🙂
After it was over, I felt ok and not strange about myself, but I knew I definitely wanted more dick.
