I sucked my first cock and I have zero regrets cheating

I’m 19, been with my girlfriend for almost a year, and she has no clue. From the first time I watched bi porn, I couldn’t stop fantasizing about sucking cock. I’d be thinking about it constantly, the taste, the weight on my tongue, the moans I’d cause. Guilt ate at me, but the urge only grew stronger until I finally snapped.
Last weekend I made a discreet Grindr account, found a 28-year-old guy nearby, and drove to his place shaking with nerves and excitement. The second his thick cock sprang out, something in me broke. I dropped to my knees and took him in my mouth like I was starving.
I sucked him for almost forty minutes straight, sloppy and eager, gagging myself deeper every time he groaned. Spit ran down my chin while I worshipped every inch, balls, head, shaft. He called me a good boy and that made me throb harder. When he finally flooded my throat I swallowed every drop, then kept sucking gently until he was hard again just so I could keep going.
I left there knowing I’m never going back. I’m in love with sucking cock now. My girlfriend still thinks I’m her sweet straight boyfriend, but I’m already planning my next hookup. I’ve never felt more alive.
