This summer trip took a turn. My sister-in-law, my stepson, and I were soaking up the sun, sitting by the pool. That’s when she told me about having an affair and how fun and exciting it is to be a cheater. I was shocked, but extremely turned on. She wanted me to be a cheater, too… I wasn’t sure I could commit to something like that, but then she said what if we made it girl-on-girl? Kept it a “close secret.” The temptation won, and she and I snuck off to fuck in the shower. I’d never been with another woman. Getting eaten out and fingered by my sister-in-law… It all felt so wrong, so dirty. But it was a sensation I needed. Never in a million years did I think we’d get caught by my stepson. He didn’t know what to think, but one thing was certain – if we wanted him to keep this a secret, he’d have to join us…
