How quick can she make me cum

We were visiting at my friends house, but it was almost time for the kids to come back from school. She was in a playfull mood, and decided that she wanted to see if she could make me cum before the kids got back. She was sucking, licking and tugging on my dick as much and as hard as she could................my timing was great..............as the kids walked in the gate I had a great orgasm. By the time they opened the door we were all dressed, and sitting in the lounge like good behaving adults..................
