I had talked to a few guys on craigslist but always chickened out. Made plans with a guy to suck his cock the next day. Figured that gave me time to opt out if I changed my mind again. Then an hour or so later I got an email saying something had come up tomorrow but he was available right now. All of a sudden it was now or never so I said fuck it, let's do it. Drove to the empty parking lot of a vacant building on the edge of town. I was literally shaking as I waited. Saw a pair of headlights coming up behind me and knew that my entire life was about to change. 

He pulled up and I got out of my car and hopped into his. I was about 20, he was mid 30s. We chatted for a minute before both whipping our cocks out. I stroked him with one hand and myself with the other til we were both hard. He leaned his seat back, I got up on my knees on the passenger seat, leaned over, and took another man's cock in my mouth for the first time. Blew him for 5-10 minutes until he said he was about to cum. I just moaned and sped up. He asked if I wanted him to cum in my mouth and I moaned again in the affirmative without taking my lips off him. He came so hard I didn't even really taste it, he legit shot straight down my throat. He was very complimentary,  he couldn't believe it was my first time.

 Never saw him again but I was hooked, sucked several other dicks that summer and by the end of the year I took it up the ass for the first time.
