I am a man in my late 20's. I'm about 6' tall, athletic build, with a long, thick cock. I am also an avid cyclist and have decided to do Seattle's naked bike ride for the firs time. I arrive at the park where the ride will start, completely naked, surrounded by hundreds of completely naked people. I had not counted on the fact that I would find the naked women around me so arousing, but almost immediately I get a massive erection, which starts drawing people's attention. Some people snicker, some seem impressed, some seem irritated, but it's completely out of my control. I keep getting more and more excited, and try to calm down my body but can't. The tipping point is when a naked teen girl walks up to me and starts berating me for getting off on what is supposed to be a community event. I try to explain that it's not intentional, but she won't listen and keeps getting more and more abusive towards me. I realize that her abuse, paired with her nakedness, is really starting to turn me on. I try to fight it but can't. The angrier she gets, the more turned on I get. I can feel my balls boiling, and I realize I'm going to cum soon. I try to fight it, but she won't give me a break, and finally it's too much for me. Without touching myself I have a massive orgasm, with huge jets of cums spurting out of me. It hits the girl square in the face and completely soaks her. Tell with creative prose, detailed descriptions of me and the girl, build tension slowly. Use lots of dialogue. Tell in present tense.
