Sucking Him Off

Been contemplating gay sex for some time. But had only experienced mutual masturbation in my teens with a friend back then.
Sat in the work's van having a a cup of coffee, at quiet spot as it was raining hard, I noticed an older guy playing with his cock sat in his car.
He knew I was there and lowered his Jean so I could see his dick more clearly.
Now or never was in my head. So when he signalled for me to join him, I got out of the van and sat next to him in his passenger seat.
He began stroking his cock again and asked me if I wanted to suck it.
Lowering my head, I first took hold of his cock and tossed him off for a few seconds, then opened my mouth to take in his cock, which was about five inches.
It felt hard, yet silky soft in my mouth, and it tasted much nicer than I'd envisaged.
I'm not sure how, but it all just came natural to me and I knew from the sounds he was making, I was sucking him off how he liked it.
I was even able to deep throat him, which surprised myself.
Really going for it, swirling my tongue all around his cock, I jacked him off and sucked at the same time and only a minute or two later he told me he was cumming.
As his cock spewed his cum, I carried on sucking and swallowing until he pulled out of my mouth.
Stroking his cock and balls, we spoke briefly about meeting up again.
I've agreed to go back to his, so I'll see, hopefully, what being fucked is all about.
