Quince was glad to finally have a workout partner. He'd been seeing another man in the gym usually around the same time he went. Quince always struggled to get in the gym consistently, but they'd seen enough to exchange contact info and finally start planning. He was happy to finally have someone else counting on him to make it, prompting him to keep the schedule they made.
Quince hadn't thought his routine would change much, surprised his new friend pushed him harder. They were older, kept their head shaved, their body built with a barrel chest. They had more experience, taking Quince as their personal project.
Quince didn't think much about it, just trying to do his best to keep consistent. He didn't notice being forced to do more reps, spend longer on the machine. Even when they went out to eat after, his buddu ordered, making Quince eat more.
Quince didn't notice when he started being patronized by the man, compliments mixed in with orders. "Good job boy. Another rep son. Keep going for daddy, you're gonna look just like me". Quince was too exhausted to think on it, loving the positive reinforcement too much to care. He didn't see how his body changed, developing the same size and mass as the daddy.
It didn't take long until they were mistaken for father son, their relationship close to outsiders. It wouldn't be long until the relationship spread to other parts of their life, Quince slowly molded to suit the daddy's desires.
