Some of the things I'd love if my wife cheated on me:

1. Getting home early after a long day at work to discover my wife getting fucked in our bed, just in time to witness him shooting cum from his bare cock into her juicy pussy.
2. Going to a local bar, sitting at the bar with her, and witness her openly flirting with men until she's got her hand on her crotch, getting his meat hard to the point we have to get in my truck so they can fuck.
3. Take her to an adult store and watch her jack off strange cocks through a gloryhole. If she really likes the cock, she slides a rubber on his meat and sucks him. If the cock is especially big, she also fucks him.
4. A continuation of #1, but after he's done shooting his load in her adulterous cunt, she begs me to eat her.
5. Similar to #1, but instead of 1 cock fucking her there are at least 2.

I have more, which I'll share soon. My dick needs to be stroked first.
