My wife and I were having sex when she was dragged off by her sister-in-law to go shopping, leaving me alone in the room with my cock erected. Then my mother-in-law knocked on the door and said she knew I was alone and came to check on me. I told her I was feeling uncomfortable mid-sex, and she gently took off her underwear, climbed onto the bed, and started sucking my cock. Her daughter's juices were still all over my cock. With a mother-in-law like her, I could never leave her daughter.
