The first time I meet my sister-in-law, I couldn't keep my eyes off of her. She's very athletic with great, sexy, strong legs and large breasts. I was staring at her all night during dinner and after while talking and having a few drinks. She was staying with us to save on the price of a hotel while in town for our wedding. We all went to bed, but I had to get up to go to the bathroom. While on my way, my soon-to-be sister-in-law came out of her room wearing only her super sexy black bra and panties. We chatted for a few minutes, and she looked down and could see that I was getting excited. She smiled at me and thanked me for the compliment. Then we went into her room and took off our clothes. She said that she couldn't have sex with me, but she did let me touch her all over, and she pleasured me manually. To say the least, I look forward to any time she comes to visit. We have told my wife about what happened that night between us, but she thinks that it only happened once.
