The nerd stupid guy who was acting as straight was playing against something dangerous. His dormant homosexuality was growing slowly deep inside his body but when he was trying to be a true straight macho the gay beast inside him woke up and he couldn't resist such a pleasure. Only bursting his shoes at the beginning and the rest of his clothes when he was with another men to f*ck, and maybe love.
My beloved Bruce Banner... getting angry, experimenting what he loves, losing control, feeling his muscles pumping out so tight, stretching and bursting the clothes, stomping and rumbling the ground, feeling the power of his growing body.
