Cheating fetish?

[favorite]

The thrill of the forbidden often turns me on. But I try not to do it again. My partner found out, and the aftermath was pretty rough.
But just the thought of it makes me pretty horny.

I've never been in a relationship, but the fantasy is one that I find quite hot. Having this loving relationship with someone, where I can get all the sex I want, yet still cheating on them. Even hotter if the person I'm cheating with would be considered much less then my partner in any way (like having a well hung boyfriend, but cheating with a guy with a small penis).
