My first taste of cum was my own, which I'd eat after jerking off, and I fantasised for many years about sucking a guy and swallowing. Growing up in a small rural town, outwardly straight, I had to wait until adulthood to spread my wings and live my dreams.
I joined a meeting website and found an older guy who was a total top and wanted to be sucked by a younger guy, and I knew I was ready. I went to his home and he led me to his bedroom, undressed me and himself, and rubbed his body and his hard cock against me then guided me to the bed. I willingly and eagerly went to work and for the first time, I was handling another man's hard cock, then licked it around the head and took it into my mouth, slid deep, and felt it press into my throat. It turned out that he was quite dominant and pushy, and held my head and started ramming his cock into my throat. It was quite overwhelming and I was struggling to not gag, and I took it in my hands to get some control. In that moment, I felt like I was a stranger to myself - sucking a cock, for real, after all these years of imagining, it was happening.
He soon started moaning and stiffened harder, and pushed into my throat. I realised now is the moment. He held my head, his cock pressing against my throat, and the first spurt of thick, warm liquid coated my throat and back of my tongue. I could not swallow with that thing pressed into my throat and I pulled back a little, gulped it down, and then came the second spurt which I immediately gulped down. Then he was cumming in waves and I was gulping in sync. I don't know how long he had gone since he last came, but he seemed to cum in bucket loads, and it seemed to last for minutes. I know it wasn't bucket loads or minutes, but when you're swallowing your first cum load, it's kind of surreal.
After some time the spurts stopped, he went slightly soft, sighed with pleasure, looked down and smiled. It was over, I'd sucked my first cock, and I hadn't spilled a drop.
What did it taste like? A little different to my own, tasted on the back of my tongue and in my throat, it seemed to fill my sinuses with a slightly bleachy smell/taste. It was not something I'd choose to use as salad dressing, but in that moment, it was pleasant. It was the taste of pleasure and of satisfying a man. It was the taste of a fantasy that became a reality. I was hooked, and it was my first of many cocks and cum loads, swallowed and never spilled. But I'll never forget my first.
