Manipulation, Deception, and Bizarre Cuckolding (?) Carousel [MF] x2

Now that it’s all over and I’ve been filled in on all the details, multiple times over, I wanted to write this out. This went down over the summer. It was and in some ways still is a confusing situation that has left me alternately perplexed, mad, hurt, and ridiculously turned on. I could probably write a book-length treatment of it, but I’ll try to just stick to a summary of sorts here.

So, rewind to this past May. My girlfriend and I are seniors about to graduate. We’d been dating for like two and a half years. She’s 21, I’m 22. She’s got a sort of all-american look thing going—shoulder-length blonde hair, light blue eyes, petite but shapely chest (b-cup?) and bubbly tight ass. She’s about 5’6”. I’m 6’, brown hair, relatively fit but nothing like an especially impressive body or anything, although I *do* have a nicely sized cock, at about 7.5”, maybe 8” inches on a good day and thick. My girlfriend, lets call her Lauren, is not a *prude* per se, but she’s definitely on the conservative side, sexually. Doesn’t like come anywhere near her face, and is a stickler about condoms.
