M4F Caught you cheating on my best friend

When I was moving to a new city, you and your fiance had been generous enough to let me move in, renting out the spare bedroom until I could advance at work enough to get my own place in the expensive real estate market.

It made sense. I was your fiance's oldest friend, and because of that you and I had built such a close relationship. Besides, you could always use a little extra help paying for the place.

And that relationship got closer. You were in grad school and I mostly worked from home if I didn't have client meetings, so we spent a lot of time just the two of us. We were closer than ever.

It was hard not to notice how gorgeous you were. Especially since you tended to lounge around in your pajamas a lot. Cotton night gowns that cut just beneath your round bubble butt and made it obvious you weren't wearing a bra. I couldn't help but stare, and on occasion, when I was coming back from the gym and peeling off my shirt, or walking out of the shower in just a towel, I thought I caught you looking too.

But of course, I respected you and my friend to much to do anything more than that.

Until that is you left your phone in the kitchen one day, and I saw all the explicit texts you'd been sending one of your classmates. Looks like you weren't the devoted and doting fiancee I thought... and if you're going to be a whore... who's to say you can't be mine?
