This is a story from when I was 18 years old. I was dating a gorgeous girl, dark hair, nice body, big breasts. We both lived at our parents houses so there wasn’t tons of opportunity to fool around.

One summer’s day we were out for a date. The sun was shining, it was a beautiful afternoon, and we were out for walk on a river path. It was busy, there were tons of people out - couples on dates, families with ice cream, old timers out for a bit of sun.

We were very horny, and would feel each other up a bit when we thought no one was looking. I’d grab her ass, she’d brush her hand against my package. We stopped and make out a bit but it was only adding to our pent up energy.

A section of the path was closed because the mud hadn’t been cleaned up yet from flooding earlier in the year. We snuck past the barricade and made our way to a few benches in an area cut into the riverbank, reinforced with concrete walls. We were only 20 feet from the busy pathway but weren’t visible to all the passers by.

We started kissing, and her hand made its way to my belt. She hurriedly undid my pants and I brought out my cock. I still remember how it felt hitting that open air under the hot sun. She glanced around, then took me in both hands and started stroking. I reached down her bra and caressed her soft breasts. She leaned over and spat on my big dick, using her spit for lubrication as she picked up the pace. We were nervous to get caught but the thrill of it played into our lust. She looked deep into my eyes as she worked me faster and faster with her small hands. I wasn’t super experienced so it wasn’t long until I felt an orgasm coming. I couldn’t hold back. My body contracted as I spurted pump after pump of hot cum everywhere. It spilled over her hands, and flowed over and down, back onto myself.

Moments later, before my euphoria had begun to subside, she was freaking out, throwing a sweater over my cum-covered cock. As my head returned to earth I turned and saw what she was seeing — a guy was standing 10 feet down the path away and had been watching us for god knows how long. He hurriedly shuffled away.

My girlfriend was very embarrassed. I felt some combination of shame, excitement and pride. Lucky guy certainly got a good show, my girlfriend was smoking hot and my cock was almost comically large on my thin frame. I calmed her down as we cleaned up, and we agreed not to speak of it again.
