I ended up having to teach the new office lady Ria, who is a bit of a natural airhead and has a big ass. My heart was racing as I took care of this suddenly cute junior colleague. One day, while working late with just the two of us, her plump ass spilled out from her tight skirt, making me fully erect. Even though I knew it was wrong, I ended up fucking her from behind and cumming inside. Regretting saying 'I did it' but acting like nothing happened the next day, I'm grateful to Ria for that, but when I see her big ass, I can't help myself...
