It's going to be long. Just warning you.
I'll start this off with a little bit of background. I've been seeing this girl for a while now. We're both in our early 20's. She's about 5'5" and rather petite. She weighs about an even 100lbs, reddish hair, soft features, she has some good C-cups and an ass that would blow your mind for someone of her size.
I wouldn't really call us boyfriend and girlfriend, although at first it seemed that's where it was headed, but it's pretty much taken the turn to nearly completely physical, which is fine for me, we're both good at fucking each other.
Now we've had plenty of sex together, we know what each other like. But this is the story that sticks out the most to me and she tends to bring it up from time to time, even called it "the fucking of her life." (hence the title)
