My friend and I joined a fitness club to start working out. One night when we were eating at a local restaurant we decided to go work out. His girlfriend Kelly was with him and wanted to go to. Kelly was tall for a girl, she was 5'10, 120 pounds, brown hair, brown eyes, 32B breast and tightest butt ever. I've always fantasized about Kelly, their was just something about her. When she would bend over I would peek down her shirt and when she would wear short skirts and sit down.
I would try to bend down with out her knowing and look up it. After eating we went to the fitness club and changed into to our gym clothes. Since it was late at night no one was in there. While working out I got the best views of Kelly and wanted her so bad. I started running on the treadmill for about fifteen minutes and noticed Jeff and Kelly were gone.
Immediately I walked into the restroom/changing room and heard somebody in one of the changing rooms making a lot of noise. I knew we were the only people there so it had to be them. They heard me open door and got really quite. I pretended to walk back out and shut it but stayed in the changing room area. I sneaked around the corner and peaked and saw Kelly laying naked on a bench with Jeff between her legs fucking her. I instantly got hard and kept on watching them. Kelly then got up and got in the doggie style position facing the door I was looking through. I knew she might could see me, but I still kept on watching.
After a few minutes of watching them Kelly looked right at me and made eye contact. I tried to hide behind the door, but peaked back around and she was starring right at me and smiled. They finally finished and Jeff started to put back on his clothes and I knew I would have to sneak back out fast. I walked out the door quickly and got back on the treadmill.
While I was walking on the treadmill Jeff walked over to me and had this smile on his face.
I stopped the treadmill and Jeff reached up and patted me on my back and said "Your turn buddy."
My heart started racing, I couldn't believe what he just said and.
He then told me that Kelly said "She saw me watching them and wanted two cocks."
I was still in shock and started walking towards the changing room.
Jeff yelled out to me "Take as long as you want."
I walked in the changing room and went to back room where I saw Kelly sitting there on the bench naked.
When she saw me she smiled and said "Get over here and fuck me."
