Post-Prom Threesome [F18/M23/F18]

*Prologue*

This story is a solid ten years old. Its origin is from a girl I met on the now mostly defunct onlyundiesclub, basically a profile-based site where guys and girls posted pictures of themselves in their underwear with contact information. When it wasn’t widely known, it was a fucking goldmine.
Anywho, I met a girl we’ll call Katie from OUC. She was a bit on the heavy side, but with gigantic breasts. We’d hung out once before, some fooling around, mostly boobs and blowjobs. As time went on, we’d mostly chat on messengers and the phone. Kind of shifted to more of a friend thing.

*Story*

Katie calls me one afternoon to see if I’m up to anything. Having just graduated college and, due to lack of employment, moving back home to the suburbs left me with not often being up to much.

Katie: “A bunch of my friends are renting a beach house for after prom. I’m going to drive down there later, want to come?”

Me: “Yes.”

Kind of a no brainer, right?

She picks me up and we drive an hour and a half to her friends beach house.
