I've been lurking here for a while and enjoying the stories. Some surprisingly high quality writing can be found here! Well done, fellow perverts.
Anyway, this story is 100% true and un-embellished. (Unlike some on here I could point to…ahem.) It may not be quite as entertaining as I could make it, but this is the sub for true stories, and I've saved this one in the proverbial wank bank for years (there's a Proverb about the wank bank, right?), so thought I'd share.
This was in the summer after high school graduation, and my girlfriend and I were in the awkward want-to-stay-together-but-know-we-probably-won't stage that serious relationships go through at that age. We had been together about a year and become pretty inseparable. She was funny, although dark in temperament, and often in mood. She was my first and I was hers. Physically, she was dark featured, thin, with green eyes. Fairly flat chested, but with an awesome, large and well-proportioned ass.
