For the last three years my son and his girlfriend travel to Florida to spend a week with his grandparents, my ex's. Marcus has been very open about sex and I use to buy his condoms and even took his girlfriend to get birth control as her parents would have freaked out. Each year on their last night there they would park by the beach and his girlfriend would give him head, or at least that is what he would tell me after each trip.

This year his girlfriend had clinicals and wasn't able to go. When he told his grandparents, they asked if I would come in her place. My in laws and I always got along, so I though what the hell. Flew down with my son and we rented a car. Had a great time and on the last night he drove over to the beach. We sat there looking at the water and talking. As soon as he was about to leave, I asked if this was his annual blow job time. He smiled with a cute smile and said yes. My mind was racing. I thought before I over think this, he has been so good to me this week, so I told him to turn around and park again. He had no idea I was about to make the offer I did. Once parked, I told him to unzip and I will do the rest. He unzipped and took out his cock. I sucked him dry. He came in my mouth three times. It has been a while since I gave head and asked if I did a good job. He told me I was perfect and if I wanted to do it again, I don't need to wait a year.

It was so wrong and I was worried I would be regret doing it, but I have no regrets. If he wants it again, I am willing to oblige.
