Yesterday morning. I was in bed next to my wife. I told her I was going to jack-off before we got up for the day. She reached over and said, "I'll help". "Great!", I said. At that moment, our daughter-in-law calls my wife's mobile phone. Our grandson is running a fever. The conversation went on forever. I grabbed the bottle of lube, squirted a bunch on my cock, and started stroking, focusing on the glans. When my wife finally finished the conversation, she rolled over and started playing with my balls while I stroked. I asked her to play roughly with my balls - pull, stretching, squeezing, etc. It didn't take long and I exploded all over my stomach. Wife grabbed the towel and cleaned me up.
