STRAIGHT GUY GOES GAY (first time gay anal hardcore erotica)

I felt him push forward ever so slightly and put another inch of cock inside of me. I was glad that he used as much lube as he did because my ass wasn't putting up much resistance at this point. However, I think that he took that as a green light because he didn't wait very long before he slid most of the way in. Or at least I had thought he was most of the way in. Turns out it was really only more like half because over the next few minutes it felt like his dick just kept going, and going, and going until he bottomed out...
