This happened almost six years ago, back when Craigslist personals was still a thing. I had always wondered what it would be like to be with a guy, and I started watching gay/bi porn to see if it was actually a turn on. It was.
I found myself jerking it to the thought of getting a blowjob from a guy and one day after smoking a shit ton of weed for courage and just enough “fuck it”, I replied to a post on the m4m personals. The poster simply wanted to come over and service a cock, that’s all. Sounded perfect to me and while I waited for him to arrive my heart was pounding and my cock was hard as rock in anticipation.
The guy arrived about fifteen minutes later and I let him inside. I was super stoned and nervous but super excited, and since I had answered the door only wearing tight boxer briefs he could see my excited state as well. I sat on the couch and he got down between my legs and massaged my cock and balls through my boxers and asked if it was my first time with another guy. I said yes and he smiled and slowly pulled down my boxers.
