Now joined by Sakura Hibiki, the newest addition to the gym who's trying to lose weight, he and Akemi decide to help her reach her goal while getting wrapped up in the daily misadventures of being in love with a beefcake trainer.

This one goes out to all my fellow Dumbbells fans. This story is meant to be a satire/parody of erotic fanfiction as a genre, whilst being an erotic fanfic itself. The goal wa to create a fun story that doesn't take itself so seriously that it's cringe. Feel free to discuss/criticize my writing. Quick notice before reading, ((Double Parenthesis)) indicate the Protagonist's thoughts. Enjoy!
