You noticed that you were gaining weight so you started running every day in the morning, even though one day you stopped in front of a gym wondering if you should sign up. A guy approached you and told you that he owned the place and that he could help you lose weight at no cost.
When you accepted, you both entered a special room in the gym, there were only you and him. He handed you some very tight clothing, just a sleeveless crop top and some shorts. Without realizing it, he started touching you while pretending to help you train and you both ended up making love.
Those "training" sections were repeated and you noticed that you started to lose weight, but he started giving you food as a reward to keep you on it. Now he invited you to a restaurant and bought you a lot of food.
"Keep eating... then we will have a training session." You knew what he meant and he watched you eat with a smile on his lips.
