[M]y camping trip turns wild when I [F]uck a married woman with an audience [cheating]

This happened well over 10 years ago. I was on a camping trip with 3 other guys. Unbeknownst to us, a small music festival was going on in town at the same time, making the park pretty busy. My female friend Chloe happened to be attending with her friend Kat. We all met up and did intros and they set up on the site next to ours. We are all early 20’s out of school.

Kat was/is a elementary school teacher. I think social studies is her favorite subject because she got really into a drunken talk to me about the rise of ancient western civilization. I don’t mean to be mean, but she is what I guess you would call a butterface? Smoking body, round ass, firm breasts, flat stomach, taller, long legs, brown hair… but looks wise kind of plain. She teaches in a rural country town. She’s married but they’re separated at the time of this story. He’s too much of a drinker, can’t hold down a job. I guess this was a tradition they had, and her husband is actually camping in the same park, I assume close by, with a few of his 90s jam band loving friends.
