I'm a man in my early 30's, fit, about 6 feet tall, average attractiveness, with an unusually thick and large cock. My name is Nate. I'm married to a lovely woman named Elizabeth, and I love her. I have a coworker named Jenny, who is a tall, leggy brunette, with long curly brown hair, a large mouth, small breasts, and a fit body. She has invited me to join her and her friends for Seattle's annual Naked Bike Ride. I've never been before. Secretly, I find Jenny very attractive, though I would never act on it, because I'm married. But secretly, I am very excited that I will get to see Jenny naked tonight. I arrive at her apartment, and she tells me that we will meet the rest of her friends at the start  of the ride. We're awkward and nervous, but there's nothing to do but move forward, so we both strip naked in her living room. I am shocked by how aroused I get at the sight of her naked body. I immediately get the biggest hard-on of my life. It's awkward...she makes a couple jokes to break the tension, but my boner just won't go away. I get embarrassed, and that only fuels my arousal more. Every comment she makes only gets me hotter and hotter. I start begging her to just give me a minute to calm down, but she's relentless in her teasing. I try to hold it in, but suddenly I tip over the edge, and I cum hard. Thick jets of cum spurting out of me, across the room, and all over Jenny's breasts, hair and face. I'm humiliated, but Jenny looks so hot covered in my cum, that my dick immediately gets hard again, to her astonishment. Tell with lots of detail, creative prose, dialogue, and build-up of tension.
