You've always worked hard to keep fit and healthy, you decided to try out gaining after stumbling across a video online. You told yourself that you were only going to gain about 20 pounds, but you found that you loved it so much that you just kept on growing, and the bigger you grew, the more confident you became. It was the best decision you'd ever made, and you were never going back to the gym ever again.
This is a reuploaded custom from Manyvids, and it has a more fat-positive vibe than the humiliation/embarrassment you usually see from ex-jock type content. I hope you enjoy~
