Late one night, I woke up and looked over at my beautiful wife. I couldn't resist, so I rolled over and tried to caress my wife awake for some late night fun. She was lying on her side with her back to me. I rapped my arm around her and slid my hand very gently down her bikini underwear and began gently rubbing her sweet spot. To my surprise, she did not wake up. Her legs were closed, and her knees were high towards her chest, so I thought I might get better access from behind. I slid my hand around and began gently caressing her. She was sound asleep and did not wake up. It must have been part of her dream as she was clearly, very excited. At first I thought she was faking it, so I decided to try a little test. Her behind had always been strictly off limits, and here was my opportunity. I tested the waters carefully. Usually, she would immediately push me away, but tonight, she laid motionless except for her heavy breathing. I couldn't hold back any longer. I began to have anal sex with her. Just as I was finishing, she woke up, startled. She immediately pulled away. I didn't know what to do or say, so I pretended to be asleep. She looked over, decided it must have been a dream, and went back to sleep. The next day, she smiled and said I must have been having some good dreams because I kept waking her up and groping her. I just smiled and agreed. They were some fantastic dreams.
