I was training this hot young girl. Her parents hired me to get her into shape. I think she is already in just the right shape with her bubble butt,  but I was not going to pass up an easy job. She seemed like a good girl until the other day. She started coming on to me,  and I was not ready for it. She was asking me to feel her ass and to make sure it was firming up because of the extra squats she had been doing. I did not want to touch her because I was not sure how old she was. She said she was 18,  so I gave her a little poke. She grabbed my hand and told me to feel it. Gracie got flustered and grabbed my cock and begged for it. Before I could really react,  she was on her knees sucking on it. She looked up at me with her deep blue eyes and ask if I wanted to go up to her room. When we got back,  I gave her a work out like no other. Her pussy and ass were so nice and smooth. She must have gotten a nice clean wax job. I was teasing her asshole with the tip of my dick until she demanded I fuck and cum inside her pussy. I think I am going to set up a different exercise for her everyday.
