I'm a man in my late 20's, I'm about 6' tall, fit, with a long, thick cock. I'm a high school English teacher, in my first year at a new school. I've decided to attend Seattle's annual Naked Bike Ride, it's my first time. I show up to the park where the ride will start, totally naked, my dick swinging free. I am awed at the sea of naked people gathering in the park waiting for the ride to start. As I set my bike against a nearby tree I'm shocked to bump into Claire, a sophomore girl from my English class, completely naked, except for a pair of prop fairy wings she's wearing. Claire is mid-height, brunette with long brown hair, she's a gynmast and her body looks lean and flexible. It also looks like she waxed her pussy for this event. Her breasts are still small, and her nipples are easily stimulated. I can't believe she's here, she's too young. It's awkward being naked together, but also I can't help but feel aroused. Since I'm naked there's no way to hide it, and her eyes go wide as she sees my large cock start to get erect. I get embarrassed and try to cover up, but i'm too big for that. The more she blushes and gets flustered, the more intense my arousal. Then i notice something dripping down her thighs... she's getting turned on too. Desperate to get out of the situation, I turn to leave, but slip on some mud and fall onto my back, accidentally kicking Claire's legs out from under her. In a total fluke, she falls on top on me and impales herself on my dick in the process. We both sit there in shock, trying not to move. Then suddenly, it's too much, and we both cum hard.
