Too small shirt (Patreon)

Trying on a shirt that clearly wasn't made for a big guy like me I found it in my family home it have like a few years... Standing there and fighting just to get every button closed was a workout on its own. Once I finally managed it, the fabric stretched tightly over every inch of my soft belly, leaving absolutely nothing to the imagination. The moment I relaxed, the buttons started popping open one by one.
