My wife is so close with her best friend that we call them sisters. One day, her "sister" stopped by to drop something off at our house. We always flirt with each other, and this time was no exception. She went to give me a kiss, and this time I got full tongue. One thing led to another, and we ended up naked and having oral sex. Afterward, we had more sex, and then more oral sex. I still see my wife's "sister" all the time, but I get aroused thinking about the time I saw all of her! -Orion, 46
