Keep Cumming

I went over to my buddies house to play some ball. To make a short story shorter, we did not play ball. His eighteen year old sister on the other hand loves to play ball, my balls to be exact. I heard some noises coming from the back room and did not know what was happening, so I went to check it out. Jessi was in the middle of rubbing one out. I could not resist. I had to watch. I lost my balance and fell into the room. She freaked out. I told her what was up and she blackmailed me. I did not mind though. I had to make her cum, so she would not tell her brother on me. I pounded her tight pussy. It got all puffy with pleasure and exploded cum all over my cock. She was a real juicy squirter, but so am I. I covered her face and hit the back of her throat with a huge load.
