My friends grandmother
I was around nineteen when this happened. My friends grandparents had a house on a lake and we went there often to swim and hang out. We had finished up swimming for the day and my friend told me to shower up first so I did. I came out of the bathroom and went into the living room where is she was sitting, we were talking about the day and as soon as the bathroom door closed she got up and walked down there. I guess she was waiting for the shower to be on because she came walking back to me and told me she wanted to see my penis. I was thrown for a loop on that one but next thing I know she is kneeling down on the floor telling me to get my shorts pulled down. She then reached out and pulled them open herself, she told me to lift up my rear so they could slide down and within seconds she had my cock in her mouth. She sucked me off so fast and hard that it almost hurt but I came in like two minutes, she looked up at me and asked me if I could still hear the shower going. I told her I could not hear it anyways, she told me to go check by the door so I did and came back telling her it was still going so no worries. I figured that she was done but she told me to sit back down but then she changed her mind and told me to follow her and grabbed my hand.
We went to one of the bedrooms next to the bathroom and she could hear the shower still going. She sat on the edge of the bed and told me to come over to her. I walked over and even before I stopped she had her fingers in my waistband pulling it down and in one quick motion my cock was all the way in her mouth. She rocked back and forth until the shower stopped running then she stopped and told me to go back out in the living room.
I did not have a second orgasm but it was one of the most thrilling blow jobs of my life.
