I alluded to this story in another thread, but the full story is...
I was 18 and single when I started sleeping with a married 33 y/o co-worker. She had a killer body, horny as hell, and I was a virgin. She's the one who taught me that a guy's not supposed to cum until she's completely satisfied, and if it takes 2 hours or more, so be it. "Hold it in until I say OK". (That's why I've never been a 2 pop guy. I could go 3 hours or more...back in the day...but I couldn't work up a 2nd pop if my life depended on it). Anyway, we'd go in the car or back to her house for lunch, after work, church parking lots...anywhere and anytime we could. Her hub worked shifts, so sometimes days, sometimes nights. Eventually he got suspicious, but never did anything. One Friday night in January, when I thought he was working the overnight, I was out drinking with some buddies. Got good and drunk, and about midnight I decided I wanted to get laid. Didn't want to call and wake her 2 kids, so I drove to the house, walked up to her BR window, and tapped on the glass. What a surprise when a man's voice asked "who's there? what do you want?". Naturally, I ran back to the car, leaving a trail of footprints in the snow. As I'm driving away, my drunken brain came to the conclusion that "If hubby is working (which he obviously wasn't), then she must have another guy there! She's cheating on me!". So my drunken ass stops at a pay phone (you younger guys might not know the term) and I called her up! Naturally, hubby picked up, but instead of hanging up, I asked to speak to her, and he and I proceeded to get into some sort of argument, the details of which are long since forgotten. It all ended badly of course, as he proceeded to beat the shit out of her, then grabbed his rifle and came after me. You haven't lived until you've raced through the streets of Smithtown at midnight in a snowstorm with a really pissed off husband with a 30-06 chasing you.
Lesson learned: If you're married, never cheat with anyone who doesn't have at least as much to lose as you do. Single people sometimes do stupid things.
