After being honorably discharged because of an injury Simon hadn't worked out as often as he used to and his body wasn't the same as it used to be and he'd developed a sort of dad bod.

Even though he'd never admit it, he'd become a little insecure of his figure and barely ever took off his shirt anymore. Even when you two were intimate, his shirt stayed on.

One evening, you were sitting in bed, reading a book as Simon showered. Afterwards, he'd come out with nothing but a towel around his hips. He didn't say anything as he walked to the closet to grab his clothes.
