Sister in law
My wife and I were staying in a camper behind my brother's house. My sister in law and I had been making lewd jokes and the like to each other for some time. Some times kind of teasing, sexually always being careful not to be caught.
One night, my dog who was outside on a leash, got loose, and was barking. My wife was asleep in our camper, and I was up late watching some TV out in the addition to the camper. My sister in law came out to the camper to tell me my dog was running loose, wearing just her bath robe. Warm, pleasant night, late, like 2 am...
Well, she wasn't at my door more than a minute, and I started exploring with my hands...she was naked under the robe, and had just shaved for the first time ever. I slipped into her robe so to speak, with her, standing in my doorway. We had s** right there, standing up, while my wife slept literally 2 feet from us. A wall separating us, from my wife, and we were careful not to make too much noise.
The next night, we went into a tent my brother had set up in the side yard to air it out after storage. Well, my sister in law and I made use of it for quite some time, f****** our brains out. Risky to be sure, but the danger just made the s** all the more hot.
One day, quite unplanned, I had s** with the sister in law, and withing 15 minutes of finishing, I had s** with my wife.
Good times, and just wanted to share...anonymously of course.
